What are the 5 network protocols?

What are the 5 network protocols?

These are:

• Transmission Control Protocol (TCP)
• Internet Protocol (IP)
• User Datagram Protocol (UDP)
• Post office Protocol (POP)
• Simple mail transport Protocol (SMTP)
• File Transfer Protocol (FTP)
• Hyper Text Transfer Protocol (HTTP)
• Hyper Text Transfer Protocol Secure (HTTPS)

What is a network layer protocols give examples?

In network layer protocols, specifically in the IP, addresses identify network adapters. For example, a typical laptop today has one network interface that uses wired Ethernet, one network interface that uses wireless Ethernet, and possibly another one that uses a cellular data connection.

What are 4 types of networks?

A computer network is mainly of four types:

• LAN(Local Area Network)
• PAN(Personal Area Network)
• MAN(Metropolitan Area Network)
• WAN(Wide Area Network)

What are the protocols of the network layer?

The following are examples of protocols operating at the network layer.

• CLNS, Connectionless-mode Network Service.
• DDP, Datagram Delivery Protocol.
• EGP, Exterior Gateway Protocol.
• EIGRP, Enhanced Interior Gateway Routing Protocol.
• ICMP, Internet Control Message Protocol.
• IGMP, Internet Group Management Protocol.

What is network Garp?

Gratuitous Address Resolution Protocol (GARP) requests provide duplicate IP address detection. A GARP request is a broadcast request for a router’s own IP address. It is used primarily by a host to inform the network about its IP address.

Which is a protocol used in the network layer?

The Internet Protocol (IP) is one of the main protocols used at this layer, along with several other protocols for routing, testing, and encryption. Suppose Bob and Alice are connected to the same local area network (LAN), and Bob wants to send Alice a message.

Which is layer 3 in the OSI model?

The network layer is layer 3 in the OSI model, and it makes the Internet possible by connecting different networks. It is also called the Internet layer.

How is the network layer different from the internet layer?

At the network layer, networking software attaches a header to each packet when the packet is sent out over the Internet, and on the other end, networking software can use the header to understand how to handle the packet.

Which is the data link layer of a network?

Data link layer: Handles communications between devices on the same network. If layer 3 is like the address on a piece of mail, then layer 2 is like indicating the office number or apartment number at that address. Ethernet is the protocol most used here. 1.
