What are the different types of network protocols?
There are three main types of network protocols.
These include network management protocols, network communication protocols and network security protocols: Communication protocols include basic data communication tools like TCP/IP and HTTP.
Security protocols include HTTPS, SFTP, and SSL..
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).
What are the 7 layers of security?
7 Layers of SecurityInformation Security Policies. These policies are the foundation of the security and well-being of our resources. … Physical Security. … Secure Networks and Systems. … Vulnerability Programs. … Strong Access Control Measures. … Protect and Backup Data. … Monitor and Test Your Systems.
What is TCP IP layers?
The TCP/IP model is not exactly similar to the OSI model. The TCP/IP model consists of five layers: the application layer, transport layer, network layer, data link layer and physical layer. … TCP/IP is a hierarchical protocol made up of interactive modules, and each of them provides specific functionality.
What are layer2 and Layer 3 protocols?
Generally speaking, Layer 2 is a broadcast Media Access Control (MAC) MAC level network, while Layer 3 is a segmented routing over internet protocol (IP) network. To better understand both layers, let’s dig a little deeper into the OSI model.
How many 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).

Which protocol is used in Web?
HTTPHTTP is a protocol which allows the fetching of resources, such as HTML documents. It is the foundation of any data exchange on the Web and it is a client-server protocol, which means requests are initiated by the recipient, usually the Web browser.
What are the types of network layer?
What are the network layers?Physical (e.g. cable, RJ45)Data Link (e.g. MAC, switches)Network (e.g. IP, routers)Transport (e.g. TCP, UDP, port numbers)Session (e.g. Syn/Ack)Presentation (e.g. encryption, ASCII, PNG, MIDI)Application (e.g. SNMP, HTTP, FTP)

What is Layer 7 in networking?
Layer 7 refers to the seventh and topmost layer of the Open Systems Interconnect (OSI) Model known as the application layer. This is the highest layer which supports end-user processes and applications. … This layer is wholly application-specific.
What is OSI model and layers?
The OSI Model Defined In the OSI reference model, the communications between a computing system are split into seven different abstraction layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
What are the most common network protocols?
TCP/IP and HTTP Because it is the most widely used network protocol, we will focus on it. Hypertext Transfer Protocol (HTTP, RFC 2616) is the server/client–based protocol used to transfer web pages across a network. A simple HTTP transaction is a good example of TCP/IP communication.
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.
