Types And Methods Of Data Transmission

Akopọ

Every photo you send, every page you load and every message you receive is far too big to push down a wire in one go. So your device chops the file into tiny labelled parcels called packets, fires them across the network by whatever route is free, and the receiving device snaps them back into order. Understanding that journey is the heart of this topic.

In this lesson you will learn the three parts of a packet and what each one carries, how packet switching moves parcels through a network, the difference between serial and parallel transmission and between simplex, half-duplex and full-duplex, and how the USB interface uses a high-speed serial connection to link your devices. By the end you should be able to pick the right method for a given scenario and justify it like an examiner.

Awọn Afojusun

  1. 1 (a) Understand that data is broken down into packets to be transmitted (b) Describe the structure of a packet (c) Describe the process of packet switching
  2. 2 (a) Describe how data is transmitted from one device to another using different methods of data transmission (b) Explain the suitability of each method of data transmission, for a given scenario
  3. 3 Understand the universal serial bus (USB) interface and explain how it is used to transmit data

Akọ̀wé Ẹ̀kọ́

Networks would collapse if every device tried to send a whole file in one unbroken stream: the wires and radio links simply cannot carry that much at once. Breaking data into packets lets many users share the same network at the same time, lets each packet take whichever route is free, and lets the receiver detect and re-request anything that arrives damaged. Exam questions on this topic reward precise description, so it pays to know exactly what a packet header carries and exactly how each transmission method behaves.
