Computer Networking Quiz

Computer Networking connects more than one computer at a time. i.e it is used for sharing data and files from one computer to another computer. Computer Networking is used to connect two or more terminals or nodes for sharing their files from one place to another place. It is used to share files through hardware and software resources. People can share their data through hardware including modems, printers, and software too.

Terminal or Node

A Node or Terminal is a device or computer that is operated or controlled by the server on a large Network. Terminal or Node is also called Client. We can also be called a terminal or node a workstation.

Components of Computer Networking:

1. Sender
2. Receiver
3. Message
4. Medium
5. Protocol

1. Sender: A sender is a person who shares information from one computer to another computer through computer networks. He sends the information by using different protocols from one device to another.
2. Receiver: A receiver is a person who receives the information that is sent by the sender from their own computer using computer networks.
3. Message: Message the text or information that is sent by the sender to the receiver using different protocols on the computer networks.
4. Medium: Medium is the physical channel through which the data is sent to the receiver. Medium is the method through which the data can be sent either in the form of PowerPoint presentations, emails, social media, written documents, or others too.
5. Protocols: The protocol means a set of rules that are used to share data from one electronic device to another device using different mediums for sending messages. Protocols are a set of rules that are used to share information. It is like an agreement.

Types of Network Address:

There are two main different types of Network Addresses.

1. MAC(Media Access Control) Address:- Media Access Control Address is the home-like address that is used to reach from starting point to its destination. MAC address is a machine address. It is also called a physical address or unique address. This address is assigned by the manufacturer that is stored in the Hardware. MAC address cannot be changed by anyone user. MAC address is a 48-bit address or 6-byte address. We cannot separate addresses by using any punctuation sign. It is separated only by using the “_” sign. we cannot use any other sign to separate bits of the MAC address.
2. IP Address( Internet Protocol): IP stands for INTERNET PROTOCOL. An IP address is a unique address. This address uniquely identifies any connected device on the internet. If we don’t have an IP address we cannot access the internet. Internet Address is assigned by the ISP. ISP stands for Internet Service Provider. An IP address is 32-bit or 4-byte. IP addresses are classified into two categories.

1. IPV4: IPV4 stands for Internet Protocol Version 4. IPV4 is of 32 decimal bits.
2. IPV6:- IPV6 stands for Internet Protocol Version 6. IPV6 is of a 128-bit Hexadecimal address.

Transmission modes in Computer Networks:

Two main types of transmission modes in computer Networks are used to transmit the data from sender to receiver using different protocols.

1. Simplex: Simplex mode is a transmission mode that is also called uni-directional mode. In this mode, data is transferred in unidirectional which means data is transferred only one side at a time. In this mode, we cannot send and receive data at a time. It is the unidirectional mode. E.g. Radio, TV, Mouse, Printer, etc. All these modes are simplex or unidirectional modes.
2. Duplex(Bidirectional): In this mode, data is transmitted directly. Both the sender and receiver can send and receive data at a time without any problem. eg. Calling, Video calling, Telephone conversation, e

Networking Devices:

Networking devices that are used to transfer data from one channel to another channel are Modems, Analog Signals, Digital Signals, Routers, Switches, Hubs, Gateways, Bridges, repeaters, etc.

1. Modem: Modem as the name implies stands for Modulation-Demolution. It is used for converting analog signals into digital signals and Digital signals into analog signals.

Modulation: Modulation is the process that converts the digital signal to the analog computer signal. It converts the computer signal into a telephone signal. Digital signal includes only binary values. It includes the binary value that can be understood by the computer only. The binary language is the language of the computer.

Demodulation: It is the process of converting the analog signal to the digital signal. Analog signal includes Human voice, Audio, videos, etc. It is used for converting the signal from one state to another form.

2. Switch: Switch is used in LAN Local Area Network. It is used for connecting two or more computers on the same network by using a MAC address. A MAC address is a machine address, physical address, or unique address that is stored in the hardware.

3. Gateway: Gateway is used to link networks by using different protocols in computer networks. A gateway is used for making the interface from one network to another network.
