what is protocol?

Answer 1

protocol


DEFINITION - In information technology, a protocol (from the Greek protocollon, which was a leaf of paper glued to a manuscript volume, describing its contents) is the special set of rules that end points in a telecommunication connection use when they communicate. Protocols exist at several levels in a telecommunication connection. For example, there are protocols for the data interchange at the hardware device level and protocols for data interchange at the application program level. In the standard model known as Open Systems Interconnection (OSI), there are one or more protocols at each layer in the telecommunication exchange that both ends of the exchange must recognize and observe. Protocols are often described in an industry or international standard.

On the Internet, there are the TCP/IP protocols, consisting of:

* Transmission Control Protocol (TCP), which uses a set of rules to exchange messages with other Internet points at the information packet level
* Internet Protocol (IP), which uses a set of rules to send and receive messages at the Internet address level
* Additional protocols that include the Hypertext Transfer Protocol (HTTP) and File Transfer Protocol (FTP), each with defined sets of rules to use with corresponding programs elsewhere on the Internet

There are many other Internet protocols, such as the Border Gateway Protocol (BGP) and the Dynamic Host Configuration Protocol (DHCP).

Also,

is a convention or standard that controls or enables the connection, communication, and data transfer between two computing endpoints. In its simplest form, a protocol can be defined as the rules governing the syntax, semantics, and synchronization of communication. Protocols may be implemented by hardware, software, or a combination of the two. At the lowest level, a protocol defines the behavior of a hardware connection.

Protocols should be distinguished from technical standards, which variously specify how to build a computer or related hardware device, or how the contents of a file are structured, or describe the static structure of a network interface. Protocols are generally used to define real-time communications behavior, while standards are used to govern the structure of information committed to long-term storage.

An agreed-upon format for transmitting data between two devices. The protocol determines the following:
# the type of error checking to be used

* data compression method, if any

# how the sending device will indicate that it has finished sending a message

* how the receiving device will indicate that it has received a message

There are a variety of standard protocols from which programmers can choose. Each has particular advantages and disadvantages; for example, some are simpler than others, some are more reliable, and some are faster.

From a user's point of view, the only interesting aspect about protocols is that your computer or device must support the right ones if you want to communicate with other computers. The protocol can be implemented either in hardware or in software.

Answer 3

Protocol is a set of rules that govern the network communications between two computers.

Without a protocol the two computers can get connected to each other but they cannot communicate ( perform data transfer).

It's like if we wanna communicate then we have to speak the same languge (protocol).

TCP/IP is the most commonly used protocol now a days.

Answer 5

It seems Kyoto Protocol is outdated. CO2 emissions have increased considerably. Steps should be taken to replace Kyoto Protocol with something more suitable for the future. Regarding India's take, India must watch the reactions of other countries and then react. That's what I think.

Answer 6

Protocol are a set of rules which govern the way two nodes communicate with each other the dictate the packet size, error checking and acknowledgement on packet delivery

Answer 7

it is a st of rules of communication which is used to make the communication possible between two networks.

for every topology and for every connection different protocol is used.

the main protocol which is used for Internet communication is tcp/ip.

the function of each protocol is depend on its use in the network.

Answer 8

There are many meanings of Protocol, you can find your in http://en.wikipedia.org/wiki/Protocol

Answer 9

its like a map or list of what ur going to follow, a blue print or a plan of preplanned action

Answer 10

a spl. set of rules in IT>
