HTTP HTTP is also known as Hypertext Transfer Protocol, it is a network protocol to access the www(World Wide Web) data. HTTP allows the data you shared data in form of Audio, Hypertext, Vedio, etc. It is known as Hypertext because it jumps from one document to another. It is similar to FTP(File Transfer Protocol) …
OSI Model describes how computer applications can communicate over a network. It was first adopted in the 1980s by all companies like telecommunication and computer companies. In today’s Moden world OSI is not used, Modern technologies used simple TCP/IP models, but OSI 7 layer model is widely being used. OSI Model shows how the network …
Unicast, Multicast, And Broadcast Cast defines the streaming of packets(data) that is transmitted to the recipient from the client-side. 1. Unicast – One to One Transmission Unicast in Computer Networking is defined, when there is one-to-one data transmission, when there is only one sender and only one receiver then Unicast Transmission is used. For example, …
