Understanding The Ethernet

Ethernet is one of the greatest innovations that happened to computer networks in recent history. It has opened the way for a lot of things that followed thereafter, including spc technology. Their combinations with wireless networks complement each other. Network users have benefited immensely from Ethernet. This has made it possible for businesses to backup data in offsite custody.

Introduction to Ethernet.

Ethernet is actually a method that connects devices to a network with access contention. This means that any device added to the network struggle to secure a link on that network so that it can be accessed by users. This is the underlying reason behind ethernet extender. this extenders bring sanity and organization in the network for harmonious communication to take place on the network

Ethernet is a great way of connecting computers on local area network, Wide area network or to the internet. This is has been made possible by utilizing the Data Link layer and the Physical layer as depicted by the OSI Model. The model demonstrates a methodical parsing of data such that two computers can communicate on the same network without data colliding. It logically changes the data that has been received from applications layer and converts it to electrical signal that can be transmitted over wires depicted as physical layer in OSI model.

When referring to data link layer, then MAC address should ring to your mind. This is an address that is used to determine host and destination computers. This done by inspecting the header information from the network layer to find out if it contains a destination MAC address. It is this MAC address that uniquely identifies all the network devices. This combination of numbers is very unique and no machine shares a similar number. That explains why many devices can be connected on the a bigger network even without IP addresses. It is important to mention that this address is detected by a switch and that where the it greatly differs with a hub.

This has formed the basis for network standards that work the world over. This enables Carrier Sense Multiple Access with Collision Detection. That means a single bandwidth can be shared by numerous devices simultaneous without causing any confusion. For instance computers on the same network can be communicating by sending requests to the server or receiving feedback from the server and each getting accurate response without conflicting with what other computers had requested.

Have you ever wondered what the case will be if every computer would its own line on the network. This would be impossible just like imagining every car having its road to avoid accidents. The same case with data communication, data is sent across a single network, naturally there will exist a collision is two computers sent data to each other and what is expected will be deadlock when this two sets of data meets along the line. For this to be avoided data communication has mechanisms through which it communicates. It actually checks the line if there is any data that has already been sent. If there is none the it allow the later to be dispatched and if there is any the it delays the later until the first to be sent is delivered then that is one the last one is released. This basically explains how Ethernet extender by use of a switch works.
