9th class computer book chapter 6 is about Computer Network. A computer network is a system in which two or more computers are connected so that they can share information, data, files, programs or other resources with each other. In the modern era, the use of computer networks is common in every sector, be it schools, banks, offices or home systems. Thanks to this network, people communicate with each other, send and receive data, and carry out business or educational tasks easily.
9th class computer book chapter 6 helps students understand how computers around the world are connected to each other to form a global network that we call the Internet.
Types of 9th Class Computer Book Chapter 6
9th class computer book chapter 6 describes different types of networks. Each type of network differs in its scope and use.
(a) LAN (Local Area Network):
This is a network used in a small area such as a school, office or college. In this network, all the computers are in the same building or nearby area. It is fast and easy to manage.
(b) MAN (Metropolitan Area Network):
This is used in a large area such as a city or university campus. MAN is a larger network than LAN and smaller than WAN.
(c) WAN (Wide Area Network):
This is the largest network that extends from one country to another. The Internet is actually the world’s largest WAN through which computers around the world are connected.
(d) PAN (Personal Area Network):
This is a network around a person, such as a Bluetooth connection between a mobile and a laptop.
All these types show how important it is to understand the scope of the network in 9th class computer book chapter 6.
Components of a Computer Network
For any network to function, there are some essential parts or components that work together to enable the exchange of data.
(a) Nodes:
These are all the devices included in the network, such as computers, printers, or servers.
(b) Transmission Media:
This is the path through which data reaches from one computer to another, such as cables or wireless signals.
(c) Network Interface Card (NIC):
This is a special card that connects a computer to a network. Every computer has a NIC so that it can communicate with other computers.
(d) Switches and Routers:
A switch connects different devices within a network, while a router connects different networks together.
(e) Network Software:
This software manages all the network functions, such as the Network Operating System which controls the connections and data flow.
All these components are explained in detail in 9th class computer book chapter 6 so that students can understand the practical structure of the network.
