Networking

A network is a group of two or more computer systems linked together. There are many types of computer networks, including the following:
  • local-area networks (LANs): The computers are geographically close together (that is, in the same building).
  • wide-area networks (WANs): The computers are farther apart and are connected by telephone lines or radio waves.
  • campus-area networks (CANs): The computers are within a limited geographic area, such as a campus or military base.
  • metropolitan-area networks MANs): A data network designed for a town or city.
  • home-area networks (HANs): A network contained within a user's home that connects a person's digital devices.

Difference Between TCP and UDP?

What is the Difference Between TCP and UDP? TCP and UDP are both protocols used to send data over the internet but they do this in a slightly different way.

When information is sent as data packets through TCP, your browser will stitch these packets back together to present you, for example, with a web page that you requested. TCP will make sure that the packets are all received and in the right order before it servers you the page so it guarantees delivery. User Datagram Protocol (UDP) on the other hand, will not perform any of the error checking that TCP does making it significantly faster. This is why UDP is better for video streaming or gaming, for example, while TCP is the go-to protocol for your normal browsing. UDP TCP Reliability: UDP is less reliable as it is a connectionless protocol. When you send a message using UDP internet protocol, it is not guaranteed if it will reach the des...

Function of Application Layer

Function of the Application Layer (Layer-7) The application layer is responsible for integrating network services with the operating system. The application layer really provides the interface between the applications and the rest of the network. Different protocols are associated with the application layer, such as HTTPS, HTTP, TELNET, FTP, SMTP and many others. We talk about these protocols as being in the application layer, but in reality, most of these protocols actually extend down through the session layer.
