How do you explain protocols?
Protocol, in computer science, a set of rules or procedures for transmitting data between electronic devices, such as computers. In order for computers to exchange information, there must be a preexisting agreement as to how the information will be structured and how each side will send and receive it.
What is communication protocol in computer?
A communication protocol is a system of rules that allow two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. Protocols may be implemented by hardware, software, or a combination of both.
What are the three types of communication protocols?
Types of Communications Internet Protocols (IP)Transmission Control Protocol (TCP) used for data transmission.User Datagram Protocol (UDP) used by programs to send short datagram messages.Internet Control Message Protocol (ICMP) messages used for diagnostic or error-generating purposes.
What is a communication protocol and explain the importance of using them?
A communications protocol is the phrase used to describe a set of rules that communication equipment adhere to when they send data to each other. If two devices are sending and receiving data but using different rules then the receiving device will not understand what was sent!
What is protocol in simple words?
English Language Learners Definition of protocol : a system of rules that explain the correct conduct and procedures to be followed in formal situations. : a plan for a scientific experiment or for medical treatment. formal : a document that describes the details of a treaty or formal agreement between countries.
Why do we need protocols?
Answer: Network protocols are needed because it include mechanisms for devices to identify and make connections with each other, as well as formatting rules that specify how data is packaged into messages sent and received.
What is the role of a protocol?
Protocol, by definition, involves the proper procedures or system of rules used to govern affairs of state or diplomatic occasions. A protocol officer is the person on your team that plans and orchestrates V.I.P. visits, ceremonies, meetings and special events.
What is use of protocol?
A protocol is a standard set of rules that allow electronic devices to communicate with each other. These rules include what type of data may be transmitted, what commands are used to send and receive data, and how data transfers are confirmed. You can think of a protocol as a spoken language.
How many types of protocols are there?
There are two common network protocols used to send data packets over a network. Together TCP as well as, UDP ahead the data packets through your device applying ports to different routers until they will connect with the last destination.
What are the key features of a protocol?
The key elements of protocol are syntax, semantics and timing.Syntax: Syntax refers the structure and format of the information data.Semantics: Semantics refers to the meaning of each section of bits. Timing: Timing refers to two characteristics: when data should be sent and how fast it should be sent.
What are the basic Internet protocols?
Common Internet protocols include TCP/IP (Transmission Control Protocol/Internet Protocol), UDP/IP (User Datagram Protocol/Internet Protocol), HTTP (HyperText Transfer Protocol) and FTP (File Transfer Protocol). TCP/IP is a stream protocol.
What is a IP protocol?
Internet Protocol (IP) – a set of rules that dictate how data should be delivered over the public network (Internet). Often works in conjunction with the transmission control protocol (TCP), which divides traffic into packets for efficient transport through the Internet; together they are referred to as TCP/IP.
What are the 4 parts of an IP address?
IP Address ComponentsAddress Class. Early in the development of IP, the IANA (Internet Assigned Numbers Authority) designated five classes of IP address: A, B, C, D, and E. Default Subnet Mask. The Network Field. The Host Field. Non-default Masks. The Subnet Field.
How many IP protocols are there?
There are two primary transport layer protocols: Transmission Control Protocol (TCP) and User Datagram Protocol (UDP).
How does the IP protocol work?
IP directs packets to a specific computer using an IP address. Converts binary packet data to network signals and back. (E.g. ethernet network card, modem for phone lines, etc.) The message would start at the top of the protocol stack on your computer and work it’s way downward.
What are the 5 layers of TCP IP?
The TCP/IP model is based on a five-layer model for networking. From bottom (the link) to top (the user application), these are the physical, data link, net- work, transport, and application layers. Not all layers are completely defined by the model, so these layers are “filled in” by external standards and protocols.
What is difference between TCP and IP?
TCP and IP are two separate computer network protocols. IP is the part that obtains the address to which data is sent. TCP is responsible for data delivery once that IP address has been found.
Why do we need IP addresses?
Internet Protocol (IP) addresses are the unique numbers assigned to every computer or device that is connected to the Internet. Among other important functions, they identify every device connected to the Internet, whether it is a web server, smartphone, mail server, or laptop.
Why do we need both IP and MAC address?
MAC Addresses handle the physical connection from computer to computer while IP Addresses handle the logical routeable connection from both computer to computer AND network to network.
Where do IP addresses come from?
One is how the computer talks to the internet at large, which is the IP address of your router. That IP address is generally assigned to the router by your internet service provider (ISP); the router, in turn, handles all the traffic from your computer out to the internet.
