Introduction to information techonology

Modulation

- It is a process of varying one or more properties of high frequencies periodic waveform.


Demodulation

-It is an act of extracting the original information from the high frequencies periodic waveform.


Bandwidth

-It is a rate of transfer measured in bits per second.


TCP/IP

-Transmission Control Protocol enable computers to communicate over a network


Node


-It work as a connection point in the network.


Client


-It is a application or system that accesses the server.


Server

-It is a series of computer that links other computers with other electronic devices together. It is often across the network.


Network Operating Systems


- It is also known as the Dialoguer. It is a software that enables the server to manage data and other networking functions.

Disk Caching


-It is a part of the RAM to speed up the access of data on a disk.

File compression


-It is a practice of packaging a file so that the disk space will not be used much.

File Decompression


-We decompress files is to view the file that we compressed.

Internet Hard Drive


-It can store, access and share our digital pictures, music files and emails.

Optical Disc Drive


-It is a disk drive that use laser lights or electromagnetic waves to read or write data.

Solid-state Storage









-It is to store presistent data with the intention of accessing through the traditional block
