Question: What Is The Main Function Of Protocol?

Why standard is important?

Standards provide people and organizations with a basis for mutual understanding, and are used as tools to facilitate communication, measurement, commerce and manufacturing.

Standards are everywhere and play an important role in the economy, by: facilitating business interaction..

How do I know if my IP is public or private?

Public IP address are the IP addresses which have to registered before use. IANA is responsible for register these IP addresses to the organizations. Private IP address are the IP addresses which are reserved by IANA and they are not routable in the internet. These addresses will be not assigned to any organizations.

How do I make my IP private?

What is my phone’s IP address? Navigate to Settings > About device > Status then scroll down. There, you’ll be able to see your Android phone’s public IP address along with other information such as MAC address.

What are the commonly used protocols?

Contents TCP/IP (Transmission Control Protocol/Internet Protocol) suite. ARP (Address Resolution Protocol) DHCP (Dynamic Host Configuration Protocol) DNS (Domain Name System) FTP (File Transfer Protocol) HTTP (Hyper Text Transfer Protocol) HTTPS (Hypertext Transfer Protocol Secure)More items…

What is the use of UDP protocol?

UDP (User Datagram Protocol) is a connectionless protocol of the internet protocol family that operates at the transport layer and was specified in 1980 in RFC (Request for Comments) 768. As a lean and almost delay-free alternative to TCP, UDP is used for the fast transmission of data packets in IP networks.

What is the main advantage of UDP?

What is the main advantage of UDP? Explanation: As UDP does not provide assurance of delivery of packet, reliability and other services, the overhead taken to provide these services is reduced in UDP’s operation. Thus, UDP provides low overhead, and higher speed.

What is an example of UDP?

Numerous key Internet applications use UDP, including: the Domain Name System (DNS), where queries must be fast and only consist of a single request followed by a single reply packet, the Simple Network Management Protocol (SNMP), the Routing Information Protocol (RIP) and the Dynamic Host Configuration Protocol (DHCP) …

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 two main functions of IP protocol?

An Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing.

What is a 192.168 IP address?

192.168. 1.1 is a common factory IP address for a consumer-grade router. If the router is used for connecting to the Internet then all computers and devices which access the Internet through it will use this address as their default gateway.

What is difference between public IP and Private IP?

Private IP Address and Public IP Address are used to uniquely identify a machine on the internet. Private IP address is used with a local network and public IP address is used outside the network. Public IP address is provided by ISP, Internet Service Provider.

What is the most important protocol?

Perhaps the most important computer protocol is OSI (Open Systems Interconnection), a set of guidelines for implementing networking communications between computers. Among the most important sets of Internet protocols are TCP/IP, HTTPS, SMTP, and DNS.

How do protocols work?

Because protocols like Internet Protocol often work together in layers, some data embedded inside a packet formatted for one protocol can be in the format of some other related protocol (a method called encapsulation). Protocols typically divide each packet into three parts—header, payload, and footer.

What is the purpose of communication protocols?

Communication protocols are formal descriptions of digital message formats and rules. They are required to exchange messages in or between computing systems and are required in telecommunications. Communications protocols cover authentication, error detection and correction, and signaling.

What is protocol and standard?

A protocol is a particular set of rules for having a conversation between two computers to convey a specific set of information. A standard (and in the networking arena, many protocols are standards) is a document that specifies something that has the overwhelming support and agreement of the standards making body.

What is the importance of protocol?

Computers make use of protocols as well, to enable them to communicate. Devices need to communicate. For example, a printer needs to send messages to a computer telling it that it has run out of paper or that it is ready to print while a computer needs to send the data it wants to print to the printer.

Where is UDP used?

UDP is commonly used for applications that are “lossy” (can handle some packet loss), such as streaming audio and video. It is also used for query-response applications, such as DNS queries.
