What is computer ?

Computers are technological devices that perform a variety of functions. A computer consists of many parts, such as a Monitor, central processing unit (CPU), Keyboard, Mouse Etc.

Computers process data that is input. They store data and produce output as well. Input is via a keyboard and mouse. Output is via display on a monitor or a printer.

How to use computers?

What happens when you start up your computer?

 "The BIOS screen"

Computer help:

The first thing you see, when you start up your computer is the BIOS screen

The BIOS (Basic Input/Output System) is a small program running in the background and usually the only time you ever notice, that it's there is during start up. The BIOS enables and controls the communication between your hardware and your operating system.

Maybe you noticed a command in the BIOS screen during start up saying "hit DEL if you want to run SETUP"

Warning!

If you don't know much about computers don't try and make any changes to your BIOS settings! If you make any wrong settings it can keep your computer from working right or even at all!

So....just enjoy looking at the black BIOS screen while you wait for your computer to start up (or go make yourself some coffee!) and leave any changes to the BIOS to the professionals / the technicians. Believe me - I DO!

The Windows start up screen

Then you'll see the Windows start up screen.

You just have to wait until your desktop shows and all your programs have loaded and you're good to go!

If you have a user account, the start up will include a login. If not, the start up will just continue and after a short while you'll see your desktop.

(OS) The Windows XP Desktop

Like previous versions of Windows, Windows XP uses a desktop for the standard interface. Think of the desktop as a workspace where you can access everything you need to operate your computer, such as system components, applications, the Internet, etc.

The desktop contains:

• Start button: one of the most important tools you will use while working with Windows XP. The Start button allows you to open menus and start applications.

• Taskbar: primarily used to switch between open windows and applications. Learn more about using the Taskbar in a later lesson.

• Icons (or graphical pictures): represent applications, files, and other parts of the operating system. By default Windows XP provides you with one desktop icon, the Recycle Bin. Learn more about the Recycle Bin in a later lesson.

 Your desktop's appearance may vary from the example shown below, especially if you bought a computer with XP preinstalled.

Mouse :

The Mouse is the device you will use for most of your interactions with your PC. It is primarily used to move the pointer arrow around the screen and to select and activate options.

The mouse buttons are used to interact with whatever is on the screen where the pointer is located. The left mouse button is the one you will use most often. Clicking this tells the PC to select an item and is called 'left-clicking'. To activate an item and use it, you will often need to click the button twice or 'double-click'.

If you click and hold the left button and move the mouse, this has the effect of 'dragging' a selected object about the screen until you release the button.

Left-clicking on text in a document will place a flashing cursor at that point, which allows you to begin typing there.

The right mouse button is usually used to bring up a small menu window that gives options specific to the selected object. To use a particular option you just left-click it.

Common right-click menu options for an object include: Open (activate, same as if you double-click), Cut (remove to be placed elsewhere), Copy (make a copy of this object) , Create Shortcut (create a shortcut link elsewhere to give quick access to this object), Delete (remove permanently), Rename (give a new name), andProperties (find out information).

You may have a third smaller button in the center of your mouse that can be rolled forwards and backwards. This mouse-wheel can be used to move up and down through documents.

The Keyboard :

Keyboards can come in a number of different layouts. QWERTY keyboards are so-called because the top line of letters, underneath the number line, begins with those six letters.

There are a number of other useful keys too. The Enter key confirms a selection, and pressing the Shift or Caps Lock keys activates uppercase letters when you type, or special characters on number keys.

There are a number of function keys beginning with F1, F2 and so on, and these are used to access different options in different programs. Other keys such as Home, Endand Page Up and Page Down allow you to quickly move about within a document.

The arrow keys move the text typing cursor up, down, left or right.

You may have a number keypad too. This acts as an alternative to the number keys above the main letter keys. Pressing the Num Lock button will switch between using the keypad as number keys, or arrow keys.

There are certain key combinations that can be used to perform particular tasks. See Keyboard Shortcuts for more information.

The Desktop

The Desktop is the main background on your screen when you are working on your PC. It consists of a background picture or 'wallpaper', any program shortcuts you have created, and the Taskbar. The Taskbar runs along the bottom of the screen (or the side, or top - you can click and drag it wherever you want to place it) and shows the date and time as well as giving you access to the Start menu. You can also put program shortcuts on the taskbar so that one click will activate a particular program. Left-clicking on the Start menu brings up the All Programs list of shortcuts to programs you have on your computer. These are often arranged in 'folders', so that you can find all the programs made by one company under a folder in their name. By holding the mouse pointer over a folder you will see a new list appear of whatever programs are within that folder. Some programs will have several related entries - so you might see a README (a document that has instructions for using the program), or an option to Uninstall (remove the program from your PC). You can access your Desktop settings by right-clicking anywhere on the background wallpaper and then clicking on Properties.

Windows

The operating system that runs all your programs and allows you to easily interact with your PC is called Windows for a good reason. It allows you to work with several different items and programs at once, all in their own 'window'. A window is like a smaller screen contained within a box on your main screen.

When you are working with a window it is brought to the 'front' of the screen, overlapping the Desktop and any other items behind it, so that you can focus on whatever is in the window.

In this way, you can have several windows open at the same time containing different programs that can be opened, closed, and re-arranged across the screen. This means you can do multiple tasks at the same time, such as playing your favorite music while writing an e-mail for example.

Files And Folders

Every item stored on your PC, whether it is a document, picture, song, game or whatever, is a file. A file can only be activated by programs that understand and are able to use it.

For example, you cannot use a music program to open a letter document. Each program on your computer understands what type of file it can or cannot use by the fact that every file has a filetype given to it.

This takes the form of a few extra letters or numbers added on to its name after a full stop. So for example, 'myletter.doc' is a file named 'myletter' with the filetype '.doc', meaning it will require a program that understands doc (document) files, such as Microsoft Word.

There are many different filetypes. Read Common File types for a list of the more common.

Any one single program or application can actually consist of many different files, all working together to achieve the same task.

This means modern computers can have millions of files spread across different locations. Folders help organize these files, so that for each particular program there can be one folder that contains all the files it needs in one place.

A folder can even contain other folders inside it called 'sub-folders'. For example, to organize your holiday pictures together you might have a folder called 'Holidays 2006' and then other sub-folders within that for each particular holiday destination, for example 'France 2006'.

You can create your own folders. You can also create shortcuts to make it easier to find particular files. Read Organize Your Files/Folders/Shortcuts to learn more.

You can take a look at an example of a folder now. On your Desktop you should see a shortcut icon called My Documents. Double-clicking this will open a new window showing the contents of the My Documents folder.

Common File Types:

If a file does not appear to have a filetype extension, open the folder it is stored in and click on Tools from the menu, then Folder Options. Click on the View tab and un-tick Hide extensions for known file types.

Benefits Of Organizing Files and Folders

Each program you install creates its own folder on your Hard Drive where it keeps most of its files. This helps your PC to find the right files to use when running a program.

Keeping files organized in folders can also help you when you are working with your PC. You can use folders to sort your files into separate categories, and place shortcuts to your favourite programs on the Desktop for easy access.

Knowing how to create, move, copy and delete folders and shortcuts can help you arrange your files much more efficiently, and allow you to easily find the files you are looking for.

Creating Folders

Double-click the My Documents icon on your Desktop. This is where your files and folders are stored.

To create your own folder, click File in the menu at the top of the window and selectNew then Folder. You could instead right-click on any of the white space in the window and select New then Folder to quickly achieve the same result.

You should see a folder entitled 'New Folder' appear. It should already be highlighted in which case you can start typing the name you want to give the folder, then press the Enter key to confirm. You can call the folder whatever you want, for the purpose of this example name it Test Folder.

If you ever need to change the name of a file or folder, just right-click it and selectRename.

Putting Files Into Your Test Folder

Double-click on your new folder to see its contents (at the moment it will be empty). To copy some files into the Test Folder, open a new window by double-clicking the My Documents icon again and navigating to the files you want to copy. For this example, just find some music or picture files you have.

To move these files into the new folder, you can just click and drag each one from the new window to the Test Folder in the old window. If you hold down the CTRL key as you click and drag, the files will be copied rather than permanently moved. To move a file back, just click and drag it back to its original folder.

You can select more than one file at once by holding CTRL and clicking once on each file you want. Then if you just drag one of the highlighted files they will all be moved. To quickly select all of the files in a folder, click to select the first one as normal, then hold down SHIFT and click once on the last file.

Instead of dragging, you can right-click on selected files and choose Cut, then right-click somewhere inside the new folder and Paste. If you choose Copy rather than Cutit will create copies rather than moving the original files.

Changing Folder Views

You can change how the files in a folder appear by using the View menu at the top of a window. Try experimenting with the different views (such as Thumbnails, Tiles, Icons, List, Details) to see which you prefer to work with. For example, the Detailsview gives you lots of information about the files, whilst the Thumbnails view is useful for collections of picture files as it displays a gallery of small thumbnail previews of the image.

Moving/Deleting/Copying Files And Folders

The menu that appears when you right-click on a file or folder gives you access to useful options such as Cut, Copy, Delete, Rename, as well as Properties which gives you more information about the files.

You can delete, cut, copy, paste and drag folders just as you can files. Remember that all files inside the folder will be moved or copied as well.

Creating Shortcuts to Files and Folders

From the menu that appears when you right-click a file or a folder, you should also see an option to Create Shortcut. If you click this option, a shortcut will be created which points to this file or folder.

If you double-click a shortcut, it has the same effect as double-clicking the folder or file the shortcut is pointing to. It is effectively a link which directs Windows to a certain file or folder.

For example, if you right-click on the Test Folder and Create Shortcut, a shortcut will appear. Shortcuts look like the file or folder they are pointing to, except that they have a small arrow in the bottom-left corner.

A shortcut like the one you have just have created for your Test Folder isn't of much use if it's in the same place as the original file or folder. Instead, drag (or Cut andPaste the shortcut like you would a file or folder, to somewhere more useful for example the Desktop. Alternatively, if you right-click a file or folder and select Send Tothen Desktop (Create Shortcut), this will automatically create a shortcut and place it on your desktop.

You could also create a separate folder on your desktop if you want to store your collection of shortcuts all in one place for easy access to your favourite files.

My Documents

My Documents is a folder on your computer that is automatically created for you, so that you can store all your own files in one place away from all the program and system folders, making them easier to find.

Double-click the My Documents shortcut on the Desktop and you will see a list of folders, within which are your files. To see what is inside a folder, double-click on it and the current window will change to show the contents.

You may see some other folders which have been automatically created for you to help you store certain types of files, such as My Music, My Pictures and My Videos. However, you do not have to use these, and you can store any of your files in any folder you want to. You don't even have to use My Documents, though it is usually easier if you do.

My Computer

Close any open windows by clicking the X button in the top-right. On your Desktop, double-click the My Computer shortcut and you will see a list of locations where files are stored on your PC's disk drives.

If you double-click the Local Disk (your Hard Disk, usually C: ) you can see all the folders that are stored on your Hard Disk - this will be the part of your PC where all your files are usually kept, unless you have extra disk drives.

The Program Files and Windows folders here are especially important, and should usually not be changed as they contain the files necessary for programs and Windows to run.

All files take up 'disk space' and your computer only has so much room to store them all. If you want to see how much of your Hard Disk you have used up so far, and how much space you have left, double-click My Computer again and this time, instead of double-clicking the Local Disk, right-click it and select Properties.

If you find you are running out of disk space, you should try to clean up some unnecessary files. Read Clean Out And Clean Up Files for more information.

If you decide you need a lot more space than you have, it is possible to buy extra Hard Drives and connect them to your computer.

If you right-click the My Computer icon on the Desktop rather than double-clicking it, and then click on Properties, you can see detailed information about your PC including your hardware devices and performance settings.

The Recycle Bin

When you delete a file, usually this just means it has been moved to the Recycle Bin. If you do not regularly empty your Bin, the files inside may take up valuable disk space.

Double click the Recycle Bin icon on your desktop to see which files are currently stored in there. If there are any files in the Bin that you want to keep and put back in the original place you deleted them from, right-click on the files and select Restore. If you are happy you no longer require any of the files in the Recycle Bin, you can remove them from your computer completely by right-clicking the Recycle Bin icon and selecting Empty recycle bin.

You should empty your Recycle Bin regularly, at least once a week..

Remove Temporary Files

Temporary or junk files are left over by programs and are usually no longer needed. They waste space and that may eventually slow your PC down.

Internet Explorer stores many of the files used on the web pages you visit so that next time you go to a site it doesn’t have to download the same files again. However, this can build up over time and take up a lot of disk space.

In Internet Explorer 6 click on Tools then Internet Options. Under the section Temporary Internet Files on the General tab, click Delete Files. Tick Delete all offline content and click OK. When finished, click OK to exit the Internet Options window.

In Internet Explorer 7 click on Tools then Internet Options and look for the section Browsing History and click the Delete button underneath. Next Click the Delete Filesbutton next to Temporary Internet Files.

The System Restore facility is a useful safety feature but it can also use up a lot of space, so occasionally it is worth clearing out the old restore points.

To do this, go to Control Panel, click on System then on the System Restore tab. Tick to turn off System Restore and click Apply, this will clear out all old restore points. Now un-tick to turn System Restore back on and use the slider to specify the amount of disk space you want it to use for future restore points.

Disk Cleanup

The Disk Cleanup system tool allows you to clean out Windows components and programs you no longer need, and remove temporary files.

From the Start menu, click on Programs> Accessories> SystemTools> Disk Cleanup.

The main Disk Cleanup window shows two tabs - Disk Cleanup and More Options. In the Disk Cleanup tab window, put a tick in the following boxes if you wish to clean out these unnecessary files:

• - Downloaded program files

• - Temporary internet files

• - Recycle bin

• - Temporary files

Click on the More Options tab and you can choose to get rid of unwanted Windows components, remove installed programs you no longer use, and remove all but the most recent System restore point.

When you have selected everything you want to clean up, click on OK then Yes to confirm you want to begin the Disk Cleanup process.

The Control Panel

The Control Panel is a collection of all the important options you will need when you want to change settings on your computer. You can find control icons for display, sound, Internet, hardware, programs, security and system settings. To access the Control Panel, click the Start menu and then click Control Panel.

Changing settings in the Control Panel can make big changes to your PC's setup. For example, the Appearance and Themes or Display options in the Control Panel can affect the quality of your screen and the size of text. Read Change Display Settings And Text Size for more information.

Click on your Start menu and then Help and Support for more help with using your PC and particular Windows features.

Alter your screen display settings

You can access your Display settings by right-clicking anywhere on the Desktop and then choosing Properties. You can also access these settings through theAppearance and Themes and Display icon in Control Panel.

You will now see the Display Properties window which has display settings arranged under five tabs - Themes, Desktop, Screen Saver, Appearance and Settings.

Themes

Under this tab you can choose a theme which will apply to all your Windows screen colours, icons and sounds.

Desktop

Click on this tab to choose a different desktop background image. Choose an image from the samples available, or Browse to locate another image on your computer.

You can also set the background at any time by right-clicking on an image in your web browser or in a folder, and selecting Set as Desktop Background.

Click Customize Desktop to open the Desktop Items window, which includes two tabs - General and Web.

On the General tab you can choose which shortcut icons to show on the desktop or use Desktop cleanup to remove items that haven't been used in a while.

The Web tab allows you to display a web page directly onto the desktop.

Screen Saver

Here you can choose a Screen saver which will appear when your computer has been idle for a specified amount of time.

These can help protect the image quality of the monitor if you regularly leave your PC for more than a few minutes. You can choose not to use a Screen saver if you find it annoying or if it interferes with other tasks.

If you select a Screen saver from the list you can see a preview and also set the idle time before it will start, and whether a password is required to use the PC when returning to the desktop - useful for privacy in an office or public environment.

You can also change the Power settings of your monitor here, including how long it should stay switched on if the PC is idle.

Appearance

Under this section you can change the style and colours of your Windows and buttons, and the size of your fonts.

Click on the drop-down arrow buttons to choose different settings, which will be previewed for you in the picture above the options.

The Font size option is useful if you find text too small to read - set to Large Fonts orExtra Large Fonts as required. Click on Advanced to choose size and colour settings for individual screen items such as windows, borders, icons and menus.

Settings

Under this tab you can set screen resolution and colour quality.

Resolution determines the number of pixels across and down the screen that are used to make up the display. The higher the setting, the more detailed your display.

A higher resolution gives you a larger screen area to work with, but if you find text and icons are now too small you may need to increase font size and use larger icons to compensate.

You can only go up to the highest resolution that your monitor can support. Experiment to find a resolution you are comfortable with.

The Color quality option should be set at Highest (32 bit) for the best quality display. Click on Troubleshoot to get Windows Help topics if you have display problems.

Clicking on the Advanced button will bring up a new window with several new tabs -General, Adapter, Monitor, Troubleshoot, Color Management, and a tab for your particular graphics card.

General

If you have set a high resolution, increasing the DPI (dots per inch) setting here will make all screen items including text appear larger.

Adapter

Information about your graphics card. Click Properties for details of the driver software you are currently using.

Monitor

Here you can increase the Screen refresh rate. Some people are more sensitive than others to the speed at which the monitor screen is updated, and may find low refresh rates can strain their eyes and cause headaches.

Tick Hide modes that this monitor cannot display, then choose the highest refresh rate using the drop-down menu. Note that LCD monitors do not have this problem, and users of these should instead set the refresh rate to the setting recommended in your monitor manual, usually 60 Hertz.

Troubleshoot

You can change your graphics card performance using the Hardware acceleration slider. Usually you will want to leave this set at Full, but if you are experiencing graphics problems you can try moving the slider down a notch.

Color Management

Allows designers and photographers to create colour profiles to improve quality for different screens and printers.

The final tab contains settings for your particular graphics card.

The advanced settings in this tab can be used for tweaking performance especially when running demanding 3D games. Useful guides for tweaking specific graphics card settings can be found at www.tweakguides.com.

You should also visit the web site of your graphics card manufacturer such as ATI or Nvidia, and download their latest driver software. Often, these driver updates contain fixes for graphics problems with certain programs or display configurations.

Alter your web browser Text Size

If you find text on web sites too small to read, you can change your settings through your browser menu by clicking on View (Page in Internet Explorer 7) then Text Size, and increase the size of the text. Depending on the way the web site was created, this may not work with all text on all pages. Sometimes web site text is programmed to stay at an exact size in order to keep it within a strict design layout.

uses of computers in schools & education ?

Computers are an integral part of schools now instead of being supplemental features. They can be used in a variety of ways to augment knowledge and application

Research

• This is the most common use for students in grades 4 through 12. When students have to write research papers on a specific topic, the computer provides the most easily accessible sources.

Faculty Usage

 Teachers at all levels use computers to administer assignments, keep track of grades or offer online instruction. Many teachers use online resources in their daily lessons.

Data Entry

• Basic keyboarding and word processing skills are taught on the computer. Knowledge of these is essential for school, college and career.

Intervention

• Computers are also being used to help learning disabled students. There are many interactive and tutorial programs online or available as software that help the challenged student with reading, math or other areas of weakness.

Virtual

• The use of computers has changed the face of distance education. Students can now be logged in at the same time, post assignments, and talk to each other on message boards while working on their college degrees.

Teacher Resource

• The Internet provides a wealth of resources for teachers like lesson plans, pre-made tests, study guides, worksheets, and other activities that only have to be downloaded and printed. There are also grade book programs and class record-keeping templates that are time-savers.

Advantages and Disadvantages of Computers in Education

Computers are the best way of teaching subjects to students. These days, all schools and colleges have computer labs where they receive practical training from their teachers. Computers assist teachers in teaching their students easily and quickly. With the help of computers and the broadband Internet facility, students can search for the concepts or things which they wish to know, by referring to relevant websites. The Internet is an ocean of information and surfing daily will increase the knowledge of these students greatly. Another advantage of computers is that the students will be able to gain knowledge of various subjects and things which are other than their school syllabus. Such form of receiving education is considered to be more effective than only learning from textbooks prescribed by the authorities. Understanding the role of computers in education is a must for all of us.

Use of computers in the classroom can help teachers to teach much more than they can do without them. The students can be shown charts, diagrams and figures while teaching practical oriented subjects such as Algebra, Geometry, Physics, Biology or Botany. Teachers can give many assignments to students which they can complete with the help of computer packages. Introduction of computers in educational institutes can help students learn different computer software and hardware, under the guidance of their teachers. For example, students will come to know which are the important parts of the computer, what are their functions and how does a computer actually work. They can learn the new packages and software tools early in life so that they can grasp vital concepts in higher studies comfortably. Importance of computer education is highlighted with the fact that computer literate students have a greater chance of grabbing the best jobs in the industry than those who do not have the required computer knowledge. Students need to be aware of all computer uses for their own benefit.

Use of computers in education does not end here. Many times, it happens that students are not able to enroll for degree courses which they are interested in due to lack of money or because the institute is far away from their residence. The introduction of distance learning has solved all these problems. The distance learning programs or online degree programs, which involve learning with the help of computers provides education at much affordable costs than the costs incurred on full-time training. Also, students living far off, in remote areas, need not travel several kilometers and come to the city as they can now learn from the comforts of their home provided they own a desktop computer with an Internet connection.

However, there are certain disadvantages of use of computers in education which we must beware of. Firstly, doing all calculations with the help of software and calculator can affect our own mathematical ability. In simple words, computers can make us a bit lazy and this can cause problems while giving examinations which are not conducted online, but need us to do all calculations by ourselves. With ready-made information available on the Internet, students will not take any interest in reading reference books and searching for information using other sources. Reading less can hamper their progress and educational future.

" From this article, on use of computers, we conclude that computers and education have become inseparable from each other. We also understood how has computer technology affected our lives in a positive way. By making wise use of computers, we can learn a lot of new things in a relatively short period. So, learn computers for a bright futur

What is the uses of computers in many careers ?

These days, employers require employees to accomplish many of their normal, daily duties by way of computers. So, lots of jobs require basic computer user skills. For example, many corporate employees use computers to perform one of more of the following tasks, regardless of their job titles.

Computers are used in every career ( Doctor, Engineer, Advocate, Police Dept. , Business, Edu. Dept.(Schools, Colleges) and many more.........

Today, computers are used in almost every aspect of our lives: in car engines, microwave ovens, video games, watches, telephones, desktops at home and work, mainframe computers in government and industry, and supercomputers expanding the frontiers of science and technology. The computer industry is one of the fastest growing segments of our economy and that growth promises to continue well into the next century.

To maintain a competitive edge, industry and commerce must continue to make creative scientific and engineering advances as well as produce high quality products. More than ever, there is a demand for a prepared work force with the scientific and technical training necessary to perform effectively on the job. Now is the time to plan your future in computing. -by computer
