A personal computer is made up of multiple physical components of computer hardware, upon which can be installed an operating system and a multitude of software to perform the operator's desired functions.

Typical PC hardware
Though a PC comes in many different form factors, a typical personal computer consists of a case or chassis in a tower shape (desktop) and the following parts:

-Motherboard - the body of the computer(not the mother).

-Power supply - Supplies power at appropriate voltages to the motherboard and internal disk drives.

-Video display controller - Produces the output for the visual display unit. This will either be built into the motherboard or attached in its own separate slot (PCI, PCI-E, PCI-E 2.0, or AGP), in the form of a graphics card.

-Removable media devices - e.i., CD, DVD, Blu-ray Disc, USB, Floppy Disk etc. that usually you put into the front of the CPU(common sense na lang).

-Internal storage - Hardware that keeps data inside the computer for later use and remains persistent even when the computer has no power.

-Sound card - Enables the computer to output sound to audio devices, as well as accept input from a microphone. Most sound cards, either built-in or added, have surround sound capabilities.

Other peripherals - Input and Output

-Text input devices (keyboard)
-Pointing devices (mouse)
-Gaming devices (joystick)
-Image, Video input devices (webcam)
-Audio input devices (microphone)

>>Image, Video output devices
* Printer
* Monitor
>>Audio output devices
* Speakers
* Headset

Any tangible(touchable) Mad parts of the computer can be considered as a hardware. Software rely so much on your
hardware that it is impossible (common sense) to run any application if you lack necessary hardware.

First they were bulky and massive. a size of a fridge can only be process 3kb. (FUNNY) Razz


Do you care about your hardware specs and want to have a greater one???

PostSubject: RAM and ROM??? are they the same?   Fri Jul 10, 2009 12:52 pm

The term memory identifies data storage that comes in the form of chips, and the word storage is used for memory that exists on tapes or disks. Moreover, the term memory is usually used as a shorthand for physical memory, which refers to the actual chips capable of holding data. Some computers also use virtual memory, which expands physical memory onto a hard disk.
Every computer comes with a certain amount of physical memory, usually referred to as main memory or RAM. You can think of main memory as an array of boxes, each of which can hold a single byte of information. A computer that has 1 megabyte of memory, therefore, can hold about 1 million bytes (or characters) of information.

Computer Hardware Guide

Computer hardware means the physical (internal and external) component of a computer and the digital circuits and computer chips inside the computer. In the recent times, the hardware has been evolved in that way that it can be controlled, configured and troubleshoots through the software. Most of the hardware has not been seen by the users as it has been embedded inside the computer. Hardware includes the internal and external components, storage controllers, removable media and communication and peripheral devices.

There are a large number of manufactures that develop the hardware components. Common hardware manufactures are Intel, Acer, Compaq, Toshiba, Samsung, HP, FujiTsu, Sonic View, Apple, Cisco and Asus. This article will provide you an overview of the most common hardware devices and their functionalities.


CPU stands for the central processing unit. It performs the calculations inside the computer that enables the computer to perform different kind of functions. It provides the data highly or bus system that moves the data between the different components of the motherboard. The speed of the data moving along the buses of the motherboard is measured in the MHz.


Motherboard is the hardware component inside the computer that provides the platform for many devices such as RAM, hard disk, peripheral devices, PC cards and controllers.


Processor is the heart of the computer that processes the instructions that are given by the user. Processor is manufactured by the different companies including Intel, AMD, Cyrix and Motorola.


RAM is the physical memory inside the computer and it stores the data temporarily. The computer’s performance depends on the RAM. More is the RAM, the better is the performance of the computer. RAM is used by the processor and other devices to store the data temporarily. There are two basic formats of the RAM SIMM and DIMM.

Video Card

Video card is an important component and it controls the display of the computer screen.

Sound Card

Sound card enables the computer to output the sound to the audio devices. Today most of the computer systems have built in sound cards in the motherboards.

LAN Card

LAN card or Network adapter is communication component inside the computer. Every computer in a network must have a LAN card to communicate with each other. Every LAN card is configured separately and a unique IP address is assigned to each LAN card.


Modem is a communication device that connects the computer with the internet. There are two types of modems internal and external.

Hard Disk

Hard disk is a storage device inside the computer. The common types of the hard disks include IDE and SCSI. Hard disk varies in sizes and capacity. An IDE hard disk is connected to the motherboard by using the Ribbon cable.


CD-ROM is a device that is used to read the data from the CD.


DVD-ROM is a device that is used to read the data from the DVD.

USB Device

A USB is a portable storage device.


Printer is a type of the peripheral device that is used to print the documents.


Scanner is a type of the peripheral devices that is used to scan the documents and images.


Monitor is a type of the hardware device that is used to display the video signals.


Keyboard is an input device that is used to give the input to the computer to process it.


Mouse is a pointing device that detects the motion of the mouse ball with the surface.
