For example, if a router is unable to deliver a packet, it will send an ICMP message back to the packet's source. IGMP: The Internet Group Management Protocol (IGMP) sets up one-to-many network connections . IGMP helps set up multicasting, meaning multiple computers can receive data packets directed at one IP address.
How many layers are there in the Internet Protocol?
It contains 7 layers, with each layer representing a different category of networking functions. Protocols make these networking functions possible. For instance, the Internet Protocol (IP) is responsible for routing data by indicating where data packets * come from and what their destination is. IP makes network-to-network communications possible.

What happens if one computer uses IP and the other does not know this protocol?
But if one computer uses IP and the other does not know this protocol, they will be unable to communicate. On the Internet, there are different protocols for different types of processes. Protocols are often discussed in terms of which OSI model layer they belong to.
What is network protocol?
Network protocols are a set of rules, conventions, and data structures that dictate how devices exchange data across networks. In other words, network protocols can be equated to languages that two devices must understand for seamless communication of information, regardless of their infrastructure and design disparities.

What is DHCP in network?
Application layer network protocols. 1. DHCP: Dynamic Host Configuration Protocol. DHCP is a communication protocol that enables network administrators to automate the assignment of IP addresses in a network. In an IP network, every device connecting to the internet requires a unique IP.
Why does DNS not carry information?
DNS queries don't carry information pertaining to the client who initiated it. This is because the DNS server only sees the IP from where the query came from, making the server susceptible to manipulation from hackers.

What is DHCP in network?
Dynamic Host Control Protocol (DHCP) uses a server to allocate an IP address and other configuration information to network devices. As a result, the device is getting a permission slip from the DHCP server to use the network. DHCP enables users to send a request to the DHCP server whenever they connect to a network.
Who created NTP?

List of Network Protocols
- There are thousands of different network protocols, but they all perform one of three primary actions: 1. Communication 2. Network management 3. Security Each type is necessary to use network devices swiftly and safely, and they work together to facilitate that usage.
Communication
- Communication protocols allow different network devices to communicate with each other. They are used in both analog and digital communications and can be used for important processes, ranging from transferring files between devices to accessing the internet. Common types of communication protocols include the following: 1. Automation: These protocols are used to aut…
Network Management
- Network management protocols define and describe the various procedures needed to effectively operate a computer network. These protocols affect various devices on a single network — including computers, routers and servers — to ensure each one, and the network as a whole, perform optimally. The functions of network management protocols include the following: 1. Co…
Security
- Security protocols, also called cryptographic protocols, work to ensure that the network and the data sent over it are protected from unauthorized users. Common functions of security network protocols include the following: 1. Encryption: Encryption protocols protect data and secure areas by requiring users to input a secret key or password in order to access that information. 2. Entit…
