Ethernet protocol

Ethernet (/ˈiːθərnɛt/) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN).

What is the role of Ethernet protocol?

At its core, Ethernet is a protocol that allows computers (from servers to laptops) to talk to each other over wired networks that use devices like routers, switches and hubs to direct traffic. Ethernet works seamlessly with wireless protocols, too.

What layer is the Ethernet protocol?

Ethernet is a layer 2 data link protocol that is widely used with the TCP/IP protocol, which resides at layers 3 and 4.

What are the three types of Ethernet?

Mainly there are three types of ethernet cables used in LANs i.e., Coaxial cables, Twisted Pair cables, and Fiber optic cables.

What are the 7 protocols?

The OSI (Open Systems Interconnection) Reference Model defines seven layers of networking protocols. ... In this model, there are four layers, including:

Ethernet (Physical/Data Link Layers)
IP/IPX (Network Layer)
TCP/SPX (Transport Layer)
HTTP, FTP, Telnet, SMTP, and DNS(combined Session/Presentation/Application Layers)

Is EtherNet a TCP or UDP?

EtherNet/IP makes use of TCP port number 44818 for explicit messaging and UDP port number 2222 for implicit messaging.

What is purpose of protocol?

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.

What is Ethernet example?

Ethernet is defined as a trademark for a system that coordinates the components of a local area network. An example of Ethernet is the cable system that connects the computer network of a small business office.

What is the main purpose of a protocol?

Protocols provide us with a medium and set of rules to establish communication between different devices for the exchange of data and other services. Protocols are needed in every field like society, science & technology, Data Communication, media, etc.

Is Ethernet IP A protocol?

EtherNet/IP is one of several network protocols that operates under the common industrial protocol (CIP), an open application layer protocol. This protocol more recently has been extended to include CIP Security, which provides secure communications between devices on the factory floor.

Is Wi-Fi an Ethernet protocol?

A WiFi connection transmits data via wireless signals, while an Ethernet connection transmits data over cable. No cables are needed to access a WiFi connection, providing greater mobility for users who can connect to a network or the Internet while moving freely around a space.

Is TCP used in Ethernet?

TCP/IP – A TCP/IP protocol suite is the collection of communication protocols needed to communicate over Ethernet. The three most important components of the TCP/IP protocol suite are IP, TCP and UDP.

What type of Ethernet is fastest?

A CAT 8 cable, for example, is the fastest you can get right now, while a CAT 5 cable is the slowest. An Ethernet cable should also have shielding. The protective layer blocks data-slowing interference by suppressing electromagnetic interference (EMI) and crosstalk that can lower a cable's overall performance.

What are the 4 types of LAN?

What are the 4 types of network cables?

Four Types of Networking Cables:

Coaxial Cable. This system is rarely used.
Shielded Twisted Pair (STP) Cable. It is mostly used in business installations. ...
Fibre Optic Cable. It consists of several layers of protective materials that surround a centre glass core. ...
Unshielded Twisted Pair Cable.

What are the 3 main 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.

What are the 3 Internet protocols?

Internet Protocol (IP) User Datagram Protocol (UDP) Transmission Control Protocol (TCP)

What are the 4 types of protocol?

Transmission Control Protocol (TCP) Internet Protocol (IP) User Datagram Protocol (UDP) Post office Protocol (POP)

Is Ethernet and TCP IP same?

Ethernet TCP/IP is the standard Ethernet interface used to connect multiple locations in a network, such as computers in an office network. It can also be used to network other communications devices, such as scanners and PLCs on a factory floor.

Is Ethernet same as IP?

Ethernet is the physical networking (link layer) protocol where the connection is actually made, while Ethernet/IP is an industrial communications protocol (application layer). Ethernet/IP combines the physical Ethernet cabling, Internet Protocol (IP) for networking within it's application layer protocol.
