P1: Explain The Function Of computer Hardware Components - Mr Betiku
Transcript of P1: Explain The Function Of computer Hardware Components - Mr Betiku
Motherboard: A major piece of hardware and holds important components together such as the CPU and memory.
BIOS: Basic input/output system has certain instructions in which this will help to start up a pc.
Power Supply Unit: Brings power from the supplied power to allow parts to work inside the computer.
Fan And Heat Sink: Cools down overheated components which are extremly hot. Ports USB: Universal serial bus is a connector which is an input device that you plug into a USB slot. The USB has a faster speed connection which helps support devices that have low speed such as Eg, Keyboards.
Parallel: The parallel port for a PC. An example is a female port which has 25pins databus. Also the male port has 25pins on one of the ends the printer ribbon would be screwed or clipped into position
Serial: The serial port has the RS-232c standard. It has to have the 25pin male port although PCs will only use 9 of the pins which will be regularly changed by the 9-pin male port. Internal Memory RAM: Abbreviation for Random Access Memory. This is a memory chip which will provide a type of memory which will allow you to have the same access time for the allocations.
ROM: Abbreviation for Read Only Memory. It will not lose its data even when the power supply is not on therefore it can be used to store things such as instructions or data.
Cache: On the computer hard drive all web resources that are visited by the user will be stored. Whether or not the user accesses a cached page that has not been updated since the user last downloaded. Cache version will be shown. Specialised Cards Network Card: Network card is a computer component that will fit into a socket on the PC motherboard with the back of the card providing one or more Ethernet connection sockets. The card is required to connect a PC to the Internet using a wired connection. The card has a hard wired MAC address which identifies the device on the network. Modern PCs can also connect to the Internet wirelessly via a PC bus card or a USB device connection.
Graphic Cards: A graphics card is the component in your computer that handles generating the signals that are sent to the monitor. It is responsible for generating all the text and pictures that are displayed on your screen. Peripherals Output Devices: They need to be connected to a processor using appropriate cabling. Examples of output devices are printers, monitors and plotter.
Input Devices: Devices that can be used to inserted into a computer or other device slots. Examples of input devices are camera, keyboard or a scanner. Cabling Coaxial: The old way of cabling networks. Has recently been used in homes creating broadband services.
Optical: A cable that has a number of optical fibers connected together, which are normally covered in their own protective plastic covers. Optical cables are used to transfer digital and data signals.
Twisted Pair: A cable which is connected together by cables being twisted around each other. Twisted pair is mostly used in telephone lines or computer applications. Backing Storage Floppy Disk: A removable disk which is protected in a plastic case that is used to store data.
Pen Drives: A small device that can be used to easily transfer files between USB compatible systems. Plug it in to any USB port and it will be automatically detected by the Operating System.
Optical Media (CD's, DVD's): Storage media that hold content in digital form and that are written and read by a laser
Flash Memory Cards: An additional piece of memory which can be easily slotted in and taken out. They are used to store additional information.
Portable Drives: Devices that used to be located in the computer case, but recently bought as an option as additional memory.
Fixed Drives: Used to store operating system and not for storing applications which needs portability, Also it stores any application which requires very fast access to data.
