HTTP (Hypertext Transfer Protocol) is an application layer protocol that is used to establish a connection between a client and a server so that the client can transfer data to the server and vice versa. HTTP is divided into two categories i.e. Non-Persistent connection HTTP and Persistent connection HTTP. In this article, we will discuss ...
AAA (Authentication, Authorization, and Accounting) is a framework that allows access to network resources. User identification is the process of authentication and then what resources access is allowed to the user is decided by the authorization. Accounting is used to determine the usage of network resources. Introduction to AAA AAA stands for Authentication, Authorization, and ...
Virtual Circuits are also known as connection-oriented switching. Virtual circuit switching establishes a predetermined path before messages are sent. In contrast, a datagram is a packet-switching technique in which each packet, known as a datagram, is treated as a separate entity. Each packet carries destination information, which the switch uses to route the packet to ...
TELNET is an acronym for TErminaL-NETwork. It is a form of protocol that makes it possible for one computer to connect to a nearby computer. It is employed as a common TCP/IP protocol for the virtual terminal service provided by ISO. The local computer is the one that establishes the connection. A remote computer is ...
There exists a routing table in the Unix operating system consisting of several tuples that contain the I.P. (Internet Protocol) address of the network, the subnet mask, the IP address of the gateway, and the name of the interface. This information is required for forwarding packets to the exterior of the network for connecting to ...
The process of multiplexing involves selecting an input line from the ‘n’ input lines and transmitting that selected line to the output line. The multiplexer is a device used for performing multiplexing. The demultiplexer is used for demultiplexing. And the demultiplexing process is just the reverse of the multiplexing process. Multiplexers and Demultiplexers are abbreviated ...
Piggybacking is a process of attaching acknowledgment with the data packet to be sent. It is an efficient solution for reducing the bandwidth utilization of the network. TCP is a full-duplex communication protocol, so piggybacking is used to transmit packets. Introduction to Piggybacking Piggybacking is a process of attaching the acknowledgment with the data packet ...
UDP is an unreliable protocol. It does not create a dedicated path for transmitting packets. So it is a connectionless protocol. Its header size is very small i.e. 8 bytes only. What is UDP? User Datagram Protocol is abbreviated as UDP. UDP works on the transport layer. UDP is a connectionless and unreliable protocol. There ...
What Are Open Ports and How Do They Work? A port is a communication endpoint where all network communications begin and end. A port recognizes a specific process or service and is assigned a number based on its specialized function. Network ports allow devices to communicate with each other remotely over the internet, regulating how ...
Flooding is a technique of routing in computer networking, in which a sender node transmits packets via all the outgoing links. Flooding is similar to broadcasting in that it happens when sender packets are transferred without routing data to each network node attached. Since flooding naturally utilizes each route in the network, flooding algorithms are ...
