Types of Network Protocol Network protocols are formal rules, procedures and formats that define communication between two or more devices over a network. Network protocols govern the end to end process of network communication. There are wide ranges of protocol used in network communication some are given below: File Transfer Protocol (FTP) – The File Transfer Protocol or FTP is a protocol used for transferring files from one computer to another computer. FTP is the preferred method of exchanging files because it is faster than other protocols like HTTP (Hyper Text Transfer Protocol) or POP (Post Office Protocol). Simple Mail Transfer Protocol (SMTP) – This protocol is used for sending e-mail messages between servers. Most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another. The messages can then be retrieved with an e-mail client using either POP or IMAP . POP is the short form of Post Office Protocol, a protocol used t...

Difference between Internet and Intranet? Internet refers to a global network that connects a large number of computers, by using routers. All computers on the internet communicate with one another using the Transmission Control Protocol/Internet Protocol (TCP/IP). Intranet is similar to internet but they differ in size and ownership. Intranet is also a computer network (especially LAN) which is privately owned by a particular individual or an organization. Intranet uses TCP/IP for sending and receiving information but it is accessible to organization members only.

What is Internet? Internet refers to a global network that connects a large number of computers, by using routers. All computers on the internet communicate with one another using the Transmission Control Protocol/Internet Protocol (TCP/IP). Evolution of Internet The foundation of the internet was given in the year 1969 when the US Department of Defence sponsored a project to connect itself with the different universities to share information with their colleagues in other U.S. cities. The project was named ARPANET (Advanced Research Projects Network) .The main motive behind this project was to develop a secure network that survives and works even after nuclear attack. By 1971 there were 30 universities participating in ARPANET. Computers in ARPANET use certain rules to communicate with each other. These set of rules are termed as Protocols. The protocol used by ARPANET was NCP (National Control Protocol). By the time NCP was out of use and TCP/IP came into the world of net...

What is computer network? A computer network is composed of multiple computers connected together for the purpose of communication, sharing data and resources, etc. The computers in a network may be linked through cables, telephone lines, radio waves or infrared light beams. Advantages of computer network: Communication - People use networks to communicate with each other by exchanging messages and information. We can take the example of a whatsapp group, video conferencing software like imo, skype, google duo, etc. In this type of software each all of us are connected with each other sharing our ideas, thoughts, discussing some topics, etc. Sharing of hardware resources - Networking of computers enables users to share hardware resources like scanners, printers, etc. Eg. Suppose there are two computer systems in your house if you want to give print then you need a printer. So what would you do, you will buy two printers for the two computer, no you will not do this because...
