Computer Networking Chapter 1 Upto 4 Review Questions

A computer network is a group of computers that apply a ready of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes.

With respect to the Computer Noesis section in the major Government exams conducted, the Reckoner Networking forms an extremely important topic and questions are frequently asked from this concept.

In this article, we bring to you the detailed data about the unlike types of Figurer networks, their definition and functions forth with the different types of node devices.

Candidates can as well take the reference equally to what this concept is all nigh through the video given below. This will enable candidates to go a more interactive interface to understand the topic and go a improve assay of the concept.

What is a Computer Network?

Before moving forwards with the article and learning more than well-nigh the types of computer networks, information technology is of import for candidates to understand what is a network and how it affects the functioning of one or more computers connected with each other.

Definition – A grouping of computers which are connected to each other and follow similar usage protocols for the purpose of sharing information and having communications provided by the networking nodes is called a Reckoner Network.

A network may be small where it may include just one organization or peradventure as large as what one may want. The nodes may farther be classified into various types. These include:

• Personal Computers
• Servers
• Networking Hardware
• General Hosts

Networking can be classified into 3 types:

1. Types of Computer Networks
2. Topology
3. Interpreters

We shall hash out all three in detail further below in this article.

Types of Figurer Networks

At that place are five master types of Computer  Networks:

1. LAN (Local Area Network) –
   • Systems connected in a pocket-sized network like in a building or a pocket-sized office
   • It is inexpensive
   • It uses Ethernet or Token-band technology
   • Ii or more personal computers tin exist connected through wires or cables acting as nodes
   • Transfer of information is fast and is highly score
2. PAN (Personal Surface area Network) –
   • The smallest computer network
   • Devices may exist connected through Bluetooth or other infra-blood-red enables devices
   • Information technology has a connectivity range of upto 10 metres
   • It covers an area of upto 30 feet
   • Personal devices belonging to a single person tin can be connected to each other using PAN
3. Man (Metropolitan Area Network) –
   • A network that tin can be connected inside a city, for case, cablevision TV Connection
   • It can be in the form of Ethernet, ATM, Token-ring and FDDI
   • It has a college range
   • This blazon of network can be used to connect citizens with the various Organisations
4. WAN (Broad Area Network) –
   • A network which covers over a country or a larger range of people
   • Telephonic lines are likewise connected through WAN
   • Internet is the biggest WAN in the world
   • Mostly used by Government Organisations to manage data and information
5. VPN (Virtual Private Network): –
   • A network which is constructed by using public wires to connect to a private network
   • There are a number of systems which enable y'all to create networks using the Internet as a medium for transporting data
   • These systems use encryptions and other security mechanisms to ensure only authorised users tin can access

For a few candidates understanding the different computer networking terms may exist a bit tough and the same applies to other computer-related terminology, applications and software. So, to upgrade your Estimator Awareness, refer to the difference between articles given beneath:

• Difference Between RAM and ROM
• Departure Between MS Excel and MS Word
• Difference Betwixt IPV4 and IPV 6
• Difference Between Firewall and Antivirus
• Departure Between Www and Cyberspace
• Departure Between Notepad and WordPad
• Difference Between Virus and Malware

Network Topologies

Given below are the eight types of Network Topologies:

1. Point to Indicate Topology – Point to Point topology is the simplest topology that connects two nodes direct together with a mutual link.
2. Bus Topology – A bus topology is such that there is a single line to which all nodes are connected and the nodes connect only to the omnibus
3. Mesh Topology – This blazon of topology contains at least two nodes with two or more paths between them
4. Band Topology – In this topology every node has exactly two branches connected to information technology. The ring is broken and cannot piece of work if one of the nodes on the ring fails
5. Star Topology – In this network topology, the peripheral nodes are connected to a central node, which rebroadcasts all the transmissions received from any peripheral node to all peripheral nodes on the network, including the originating node
6. Tree Topology – In this type of topology nodes are continued in the form of a tree. The office of the primal node in this topology may be distributed
7. Line Topology – in this topology all the nodes are continued in a straight line
8. Hybrid Topology – When 2 more types of topologies combine together, they grade a Hybrid topology

Network Devices

Discussed below are a few important network devices from the examination betoken of view:

• Network Repeater – Used to generate incoming electrical, wireless or optical signals
• Network Hub – It is a small network device. Information technology joins multiple computers together to form a single network segment. On this segment, all computers tin can interact with each other
• Network Switch – Information technology is a small hardware device which joins multiple computers together with a single LAN
• Network Router – This device interfaces in multiple networks whose chore is to re-create packages from 1 network to another. Information technology provides connectivity within enterprises, betwixt Enterprises and the Cyberspace and within an ISP
• Network Span – It reads the outermost section of the data bundle to tell where the message is going. It reduces the traffic on other network segments.
• Modem – This device converts digital signals into analog signals. Information technology is always placed between a phone and a figurer organization

All the information given higher up will help candidates prepare themselves for the Computer Knowledge section in the upcoming Government exams and ace it.

Sample Questions – Computer Networks
