What are the 4 types of networks?
Types of Computer NetworkLocal Area Network (LAN)Metropolitan Area Network (MAN)Wide area network (WAN).
What is Layer 7 in networking?
Layer 7 refers to the top layer in the 7-layer OSI model of the Internet. It is also known as the “application layer.” It’s the top layer of the data processing that occurs just below the surface or behind the scenes of the software applications that users interact with.
What is TCP vs UDP?
TCP is a connection-oriented protocol and UDP is a connection-less protocol. TCP establishes a connection between a sender and receiver before data can be sent. UDP does not establish a connection before sending data.
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.
Why are protocols needed for communication?
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 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.
What are network protocols?
A network protocol is an established set of rules that determine how data is transmitted between different devices in the same network. Essentially, it allows connected devices to communicate with each other, regardless of any differences in their internal processes, structure or design.
What is communication protocol and its types?
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. The protocol defines the rules, syntax, semantics and synchronization of communication and possible error recovery methods.
How many types of network protocols are there?
three typesGenerally speaking, networks have three types of protocols — communication, such as Ethernet; management, such as the Simple Mail Transfer Protocol (SMTP); and security, such as Secure Shell (SSH).
What is protocol give example?
A protocol is a standard set of rules that allow electronic devices to communicate with each other. … Examples include wired networking (e.g., Ethernet), wireless networking (e.g., 802.11ac), and Internet communication (e.g., IP).
