A computer is a device where digital information is stored in the form of electronic information. At present, the number of computers used may surpass the number of users, so extensive is the utility of this extremely propitious device. There are four basic operations of a computer viz. 1.) Input 2.) Processing 3.) Storage 4.) Output. Although a basic idea of a computer might include components like keyboard, printer, scanner, monitor, speakers and so on, commonly known as the peripherals, The central processing unit (CPU) is considered to be “the computer”.
Hardware of a modern personal computer are as follows:
i. Motherboard:
A motherboard is the most important central component of a PC (Personal Computer). It is a printed circuit board (PCB) and is the main connector to the other crucial components of a system. It is also referred to as a main board or system board and is known as the logic board in case of Apple computers. It is casually called the mobo. The components attached to the motherboard that are of significance for the normal running of the PC are the Basic Input/Output System (BIOS), the memory, the Central Processing Unit (CPU), the graphics card, sound card, hard drives, disk drives and other external ports and peripherals.
ii. CPU:
The CPU is the primary element that carries out the instructions of the computer programs. The program is stored as a sequence of numbers in the computer memory. The function of the CPU is to retrieve an instruction from the program memory and decodes it and divides it into parts of information significant to the various parts of its own, executes the information and finally writes it back in another form of memory. This is the cycle of processes carried out by a CPU. It is fitted directly onto the motherboard via a socket interface and is usually accompanied with a fan to avoid overheating.
iii. RAM(Random Access Memory):
RAM is where the computer data is stored. It is a collection of integrated circuits that allow access to stored data in a random order. It processes information when we start a program it is loaded into the RAM to be run. There is a certain amount of RAM memory that the respective motherboard can take and accordingly add more RAM onto the RAM slots provided on your motherboard.
iv. Expansion Card:
An expansion card is a printed circuit board (PCB) that is inserted into an expansion slot of the motherboard. They expand on certain features that are not offered by the motherboard.
v. Optical Disk Drives:
Optical drives store data on optical discs like CDs, DVDs, and BDs (Blu-ray discs) which hold much more information than classic portable media options like the floppy disk.
vi. Hard disk drives:
It is the major storage device that stores digitally encoded data on rapidly rotating platters with magnetic surfaces. It is permanently fitted onto the CPU and stores massive amounts of data and helps retrieve it.
vii. BIOS (Basic Input/Output System)
The BIOS contains all codes required to control the keyboard, display screen, disk drives and a number of miscellaneous functions. It also configures correct settings for these components at the start up.
viii. Internal Bus:
This connects the CPU to all the internal expansion cards. It is manufactured and comes alongwith the motherboard.
ix. External Bus:
This connects the external peripherals like printers to the computer.
x. Chipset:
This is the main component on the motherboard and it passes information between each of the computer components.
xi. Sound Card:
The Sound card allows the output of sound via audio devices and also accept input from external audio source.
These are the basic components of a computer which are essential elements for the proper functionality the computer.
