define protocol and discuss any three types of protocol?
Answers
Answer:
protocol meaning is that it a set of mutually accepted and implemented rules at both ends of the communications channel for the proper exchange of information.
Types of Protocols:-
A protocol technologies is required for communication between computers. To connect different types of computers from a variety of computer vendors, protocols must be first standardized. The ARPA (Advanced Research Project Agency) part of the US Defense program was the first to introduce the concept of a standardized protocol. ARPA is a resource sharing network connecting different computers at universities and laboratories in the US. The concept of the protocol and its layer structure, emerged from the ARPA network. ARPA developed an integrated network using packet protocol and is also renowned for its development of packet switching.
TCP:-
Transmission control protocol is used for communication over a network. In TCP data is broken down into small packets and then sent to the destination. However, IP is making sure packets are transmitted to the right address.
Internet Protocol (IP):-
IP is also working with TCP. It is an addressing Protocol. IP addresses packets route them and show different nodes and network Unless it reaches its right destination. The IP protocol is developed in 1970.
FTP:-
File transfer protocol is basically used for transferring files to different networks. There may be a mass of files such as text files, multimedia files, etc. This way of file transfer is quicker than other methods.
SMTP:-
Simple mail transfer protocol manages the transmission and outgoing mail over the internet.
HTTP:-
HTTP is based on client and server model. HTTP is used for making a connection between the web client and web server. HTTP shows information in web pages.
Ethernet:-
Ethernet is a most important for LAN communication. Ethernet transmits the data in digital packets. If any computer wants to use this protocol they should contain Ethernet Network Interface Card (NIC). The card is implemented with unique address code fixed in the microchip.
Answer:
Protocol Definition: It is a digital language through which we communicate with others on the Internet. protocol meaning is that it a set of mutually accepted and implemented rules at both ends of the communications channel for the proper exchange of information. By adopting these rules, two devices can communicate with each other and can interchange information. We can't even think of using the Internet without Protocols. Each protocol is defined in different terms and different use with unique name. Message travel from sender to receiver via a medium (The medium is the physical path over which a message travels) using a protocol.
Protocols' are developed by industry wide organizations. All data of protocols are stored in binary information. Protocol language is a mixture of bits, characters, integers, etc.
Each of it has its own access method of exchanging data over a computer network, such as LAN, Internet, Intranet, etc. One of the most common and known protocol example is HTTP, that is used over the world wide web. there are different protocols used in internet that are
• TCP/IP (Transmission Control Protocol/Internet Protocol)
• ARP (Address Resolution Protocol)
• DHCP (Dynamic Host Configuration Protocol)
• DNS (Domain Name System)
• FTP (File Transfer Protocol)
HTTP is an application-layer protocol that is used for transferring files on the internet. It is used by web browsers and servers use to communicate.
There are different types of protocols and different uses of protocol.

Telnet
Telnet is an established with some rules which are used to connect to another computer. Telnet is mainly used for the remote login process. The computer which is requesting for a connection that is a local computer and which is accepting the connection that is a remote computer. If you give a command in a local computer that command is executed in the remote computer. Telnet is also based on client and server model.
Gopher
Gopher is an application layer protocol, which is used for searching and retrieving documents from remote sites. This is possible to start an online connection with other computers through gopher.
Transmission Control Procedure
As important as it is that there should be one accepted standard that allows all types of machines to communicate. There are several different protocols in use today. These are:
Character-orientated Protocols (COP)
Each character has its own meaning in character-orientated protocols. A character may be a data byte or a control byte during transmission. The main COP in use today is known as Bisync or binary synchronous. Each character sent is transmitted using the ASCII code. Control bytes obviously have values in ASCII of between 00 and 1F, whereas data bytes have values between 20 and 7F.
