What are the types of network protocols?

Types of Protocols

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 are the two popular network layer protocols?

IP and IPX (Network Layer) Because of the growth in Internet-based networks, IP/TCP are becoming the leading protocols for most networks.

Is ICMP a Layer 2?

In other words, ICMP messages must be encapsulated in IP packets. Consider it as similar to ARP which could be considered to be “at the top” of layer 2, while using the Ethernet protocol to actually send packets. Therefore, in the topic on TCP/IP-based layered network, ICMP is shown as a layer 3 protocol.

Is ICMP a layer 4?

ICMP headers are at Layer 4, just like TCP and UDP, so many will answer “Layer 4.” Others argue ICMP is a Layer 3 protocol, since it assists IP (a Layer 3 protocol), and has no ports.

What OSI layer is DHCP?

Layer 2

Is DNS a layer 2 or 3?

DNS is a application layer protocol, because DNS query and answer is the application level communications. Application layer only understand the query and answer section in the DNS packet. so application layer DNS query/answer is encapsulated in layer 4 udp then layer 3 IP…..and so on.

What OSI layer is TLS?

Transport Layer Security

What layer is UDP?

transport-layer

What is TCP IP layers?

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 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.

What is TCP IP basics?

TCP/IP is an abbreviation for Transmission Control Protocol / Internet Protocol. It is a set of protocols that define how two or more computers can communicate with each other. The protocol is effectively a set of rules that describe how the data is passed between the computers.

What are the five layers?

The Five Layers

The Troposphere. . The Troposphere is the first layer above the Earth’s surface and the closest to the ground.
The Stratosphere. . This layer begins at around 50 km above ground level.
The Stratopause. .
The Mesosphere. .
The Thermosphere. .
The Exosphere. .

Which is the hottest layer of the atmosphere?

thermosphere

What layer are satellites?

You can consider most satellites to be in space, but in terms of the Earth’s atmosphere, they occupy regions called the thermosphere and the exosphere. The layer through which a satellite orbits depends on the satellite’s function and the kind of orbit it has.

Which layer has the highest pressure?

lowest layer

What layer does most weather occur in?

troposphere
