Computer Hardware and Software

1.1 Computer Components

Computers come in all types and sizes. There are primarily two main sizes of computers. They are: Portable and Desktop.

The portable computers come in various sizes and are referred to as laptops, notebooks, and hand-held computers. These generally denote different sizes, the laptop being the largest, and the hand-held is the smallest size. We will talk about the desktop computer.

Computers are made of the following basic components:

1. Case with hardware inside:

1. Power Supply - The power supply comes with the case, but this component is mentioned separately since there are various types of power supplies. The one you should get depends on the requirements of your system.

2. Motherboard - This is where the core components of your computer reside which are listed below. Also the support cards for video, sound, networking and more are mounted into this board.

• Microprocessor - This is the brain of your computer. It performs commands and instructions and controls the operation of the computer.

• Memory - The RAM in your system is mounted on the motherboard. This is memory that must be powered on to retain its contents.

• Drive controllers - The drive controllers control the interface of your system to your hard drives. The controllers let your hard drives work by controlling their operation. On most systems, they are included on the motherboard, however you may add additional controllers for faster or other types of drives.

3. Disk drives - hardware on which you can store files. Disk drives are assigned a letter. For example, most users store their files on their hard disk, which is typically labelled "C:". On disk drives your files are permanently stored. Also, normally, your operating system is installed on hard disk. Hard disks use the magnetic recording techniques. Hard disks share the major benefits of magnetic storage -- the magnetic medium can be easily erased and rewritten, and it will "remember" the magnetic flux patterns stored onto the medium for many years. Hard disk has about 80 Gigabytes of memory capacity.

4. CD-ROM drive(s) - This is normally a read only drive (CD-ROM) where files are permanently stored. There are now read/write (CD-RW) drives that use special software to allow users to read from and write to these drives. CD has about 800 Megabytes of memory capacity.

5. Floppy drive(s) - A floppy is a small disk storage device that today typically has about 1.4 Megabytes of memory capacity. Floppy disk is labelled "A:".

6. Other possible file storage devices include DVD devices, Tape backup devices, and some others.

1. Monitor - This device which operates like a TV set lets the user see how the computer is responding to their commands.

2. Keyboard - This is where the user enters text commands into the computer.

3. Mouse - A point and click interface for entering commands, which works well in graphical environments.
