Computer Components

Computer Components : Computers come in all types and sizes. There are primarily two main sizes of computers. Portable
Desktop
The portable computer comes in various sizes and are referred to as laptops, notebooks, and hand-held computers. This document will mainly talk about the desktop computer although portable computer issues are also discussed in various areas.
Computer Components:
Computers are made of the following basic components:
Power Supply - The power supply comes with the case, but this component is mentioned separately since there are various types of power supplies. Motherboard - This is where the core components of your computer reside which are listed below. 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. 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. Hard disk drive(s) - This is where your files are permanently stored on your computer. Also, normally, your operating system is installed here.
CD-ROM drive(s) - This is normally a read only drive where files are permanently stored. There are now read/write CD-ROM drives that use special software to allow users to read from and write to these drives.
Floppy drive(s) - A floppy is a small disk storage device that today typically has about 1.4 Megabytes of memory capacity.
Other possible file storage devices include DVD devices, Tape backup devices, and some others.

Keyboard - This is where the user enters text commands into the computer.
Mouse - A point and click interface for entering commands which works well in graphical environments.

Ok, thats all about Computer Components

Standard Computer Components

A computer is made up of many components that must work together simultaneously to power the machine. Computer hardware varies in speed, performance and features and is usually aimed toward a specific type of user such as those who simply want to browse the web or more run more intensive applications. Having a basic understanding of standard computer components can be help when making buying decisions.

Computer Case

Computer cases hold all internal hardware components. Cases come in various sizes and colors. The size of your case will dictate which motherboard options you have. ATX (full size) cases support both ATX and micro-ATX motherboards. Micro-ATX cases are limited to micro-ATX motherboards. How many internal hard drives and disk drives you can install is also limited to the amount of hard drive and disk drive bays inside the case.

Motherboard

The motherboard is essentially the hub of the computer; it houses all of the chips and cards that power the machine. Because motherboards are designed to work for a specific kind of hardware, knowing what type of motherboard you're using and what is compatible with the motherboard is vital when building a new computer or making upgrade decisions.

Graphics Card

The graphics card, also referred to as the video card, renders the images displayed on your computer monitor. While most motherboards come with integrated video, graphics cards are faster and offer more features compatible with modern 3-D technology and disk-based technology such as Blu-ray. Although many factors are involved, interruptions in video playback and slowdown in 3-D applications is usually the result of integrated video that cannot keep up.

Hard Drive

The hard drive stores all content you save to your computer, along with the operating system. Hard drives come in internal or external variants, with external drives usually costing more because the setup is easier. Although hard drives vary in speed (measured by revolutions per minute or RPM), even the slowest drives are suitable for most applications.

Mouse & Keyboard

Probably the most recognizable peripherals, the mouse and keyboard are essential to any desktop computer. There are various keyboard designs and sizes available to suit office, gaming or web browsing use. The same is true for the mouse, with some having additional side buttons or extra buttons on the scroll wheel. Wireless mouse and keyboards are becoming more common as they have become more reliable as the technology has improved, resulting in increased battery life and fewer disconnections.
