The article will help us to understand the technicalities of Computer function. Beginners must know this, it is more useful to design the career in any of this parts. Two technical parts make a computer ready to use.
Hardware
Software
Hardware: Hardware is a physical component of computer, like in earlier blogs we have already discussed about the Input device, CPU, Out Device.
Parts of Computer:
- Keyboard - Keyboard generally (with 105 Keys) is used QWERTY mechanism, this mechanism is nothing but keys are set on board as like manual typewriter key board. Keys on the keyboard are - Numerical keys (0-9), Alphabetical Keys (A-Z), special characters (@#$%^&*), function keys (F1 - F12) and other supporting key like caps lock, tab, shift key, space bar, delete key and so on.
- Mouse - An input device, also an direct input, A mouse mainly is two finger operative device fits under our palm, a typical mouse has two buttons (left button and right button) and a scroll wheel, the display of mouse can be seen on screen as 2D cursor frequently blinking. now-a-days optical mouse are preferred as durable than track ball mouse.
- CPU - (Central Processing Unit) every computer has CPU, which consists of mother board (an universal card on which core components like processor, ICs and wiring are seen, mainly System board/Motherboard which holds the CPU, BIOS (Basic Input Output System), Random Access Memory and other parts, and has slots for expansion cards
BIOS - Basic Input Output System holds the basic information about the configuration of computer, it contains coded information used to boot (initial start) computer, this coded information is nothing but the information about your hardware and software parts.
Motherboard: Motherboard is basic circuit plate where lot of wiring and electronic components are connected, like Power Supply, Input Device, Output Device, storage device, microprocessor are connected to mother board, it consists of slots where different cards like graphic reader, RAM, internet, LAN are fixed. Buses: Like PCI bus: (Peripheral Componenet Interconnect), ISA bus (Industry Standard Architecture), USB (Universal Serial Bus), AGP (Advanced Graphic Port) are Slots on which different cards are fitted. Connectors to outer peripherals like Keyboard, Mouse, Game pad, Printer, Monitor, Modem, Plotter, Image scanner, Webcam, Speakers, Monitor, USB Ports, LAN Ports
What is microprocessor: Usually we all hear about the microprocessor like celeron, intel, AMT Athlon and so on, the words relates to microprocessor, its a brain of computers, it is associated with each and ever computer. Function of microprocessor it to regulate and monitor the functionality of hardware and software, each and every function of computer is regulated, the speed of microprocessor itself shows the configuration of computer. we all hear about P1, P2, P3, Dual Core, Core 2Duo with MHz(mega hertz) or Ghz (giga hertz) this technical words relates to the speed of working of computer and so on. "Intel inside" is the major partner to produce microprocessor, preferably every 9 of 10 computers holds microprocessor of Intel. While buying the computer, the basic configuration is to know about microprocessor technicality.
Monitor are of two types like CRT (Cathode Ray Tube) and (LCD) Liquid Crystal Display which is Flat screen monitors.
Printer are also of two types mainly, DMP (Dot Matrix Printer) and Laser/copier. DMP - mainly consists of 9-pin head used to print the data, which is noisy and more time consuming as compared to laser printer. Laser Printer - Rich quality printing like image, photo printing is done on this type of printers, it mainly consists of cartridge (Black/Colour) based technology, the mechanism is that ink is spread on paper through these cartridges.
These are basic hardware components associated with each basic computer. Apart from these there are additional components like Modem, Webcam, Hard Disk, Multimedia, LAN and so on.
