A restore tool reverses the process and returns backed up files to their original form Communicating Digital Content Communicating Digital Content This module covers the basics of digital communications, different types of networks and network standards that enables devices to talk or communicate together. Also discussed in this module the different communication media specifically on wired and wireless type of media that users enjoy and enable them to connect real-real time and take them closer to each other. Upon completion of this module, you will be able to answer the following questions: Discuss the purpose of the components required for successful communications and identify various sending and receiving devices Differentiate among LANs, MANs, WANs, and PANs Differentiate between client/server and peer-to-peer networks Explain the purpose of communications software Describe the various network communications standards and protocols
Digital Communications Digital communication technology like mobile technology and online platforms has greatly influenced and expanded the way people interact and consume news and information. Today the world has become digital due to advanced technology. Improvement of information technologies and telecommunication system has enhanced communication, expanding the traditional scope of communication Digital communications describes a process in which two or more computers or devices transfer data, instructions, and information.
Since digital communication is not possible if there are no connected devices designed to the purpose of communicate, hence the network came out. Networks A network is a collection of computers and devices connected together via communications devices and transmission media Advantages of a network include:
Types of Computer Networks There are various types of computer networks available. We can categorize them according to their size as well as their purpose. The size of a network should be expressed by the geographic area and number of computers, which are a part of their networks. It includes devices housed in a single room to millions of devices. A local area network ( LAN ) is a network that connects computers and devices in a limited geographical area It’s a group of computer and peripheral devices which are connected in a limited area such as school, laboratory, home, and office building. It is a widely useful network for sharing resources like files, printers, games, and other application. The simplest type of LAN network is to connect computers and a printer in someone's home or office.
A wireless LAN ( WLAN ) is a LAN that uses no physical wires. This type does not use wires to connect devices, instead it uses radio signals from one wireless device that distribute the signal.
