Ethernet and types of Network | LAN, WAN & Others | Computer Networking - Computer Work 22
Ethernet is a type of communication protocol developed at Xerox PARC in 1973 by Robert Metcalfe and others, connecting computers to a network via a wired network. It is a widely used LAN protocol, also known as the Alto Aloha Network. It connects computers within the local area network and the local area network. Many devices such as printers and laptops can be connected via LAN and WAN within buildings, homes, and even small spaces.
It provides a simple user interface that helps to connect various devices easily, such as switches, routers, and computers. A local area network (LAN) can be created with the help of a single router and a few Ethernet cables, allowing communication between all connected devices.

With cables and low-speed Ethernet devices, most Ethernet devices are compatible with back-to-back. However, the connection speed will be as fast as the normal minimum. For example, a computer will only be able to transfer and receive data at 10 mbps.
Wireless networks have replaced Ethernet in many areas; However, Ethernet is still the most common form of cable connection. Wi-Fi reduces the need to use the cable as it allows users to connect smartphones or laptops to a network without the required cable.
Different types of local area network
A local area network device with copper CAT5 / CAT6 cables is connected to a fiber optic cable via fiber optic media converters. The gap coated by the network will increase considerably with this fiber optic cable extension. There are many kinds of local area network networks mentioned below:
Fast local area network: this kind of Ethernet is typically supported by a twisted combine or CAT5 cable, capable of sending or receiving information at concerning a hundred Mbps. They care for 100Base and 10/100Base local area network on the fiber facet of the connective once any device like a camera, laptop, or alternative network is connected. Fiber optic cable and twisted combine cable victimization quick local area network to make connections. 100BASE-TX, 100BASE-FX, and 100BASE-T4 are 3 classes of quick local area networks.
Gigabit t local area network: This kind of local area network is an Associate in nursing upgrade from quick Ethernet, which uses fiber optic cable and twisted cable to make connections. It will transmit information at a rate of one thousand Mbps or 1Gbps. In the modern world, a gigabit local area network is extremely common. This kind of network conjointly uses CAT5e or alternative advanced cables, which might transmit information at a rate of ten Gbps.
The main purpose of developing a gigabit local area network was to totally meet user necessities, like quicker information transfer, quicker communication network, and more.
10-Gigabit Ethernet: this kind of network will transmit information at a price of ten Gigabit/second, which is taken into account to be the foremost advanced and quickest network. It uses CAT6a or CAT7 twisted cables and fiber optic cables similarly. This network is burnt up to ten, 000 meters with the assistance of fiber optic cable.
Switch Ethernet: this kind of network involves adding switches or harps, that help to boost network performance as every operation purpose on the network will have its own ten Mbps dedicated association rather than location sharing. Rather than employing a crossover cable, a regular network cable is employed once the button is employed on a network. On the newest local area network, supports ten00Mbps up to 10 Gbps and 10Mbps up to 100Mbps over a quick local area network.
Benefits of Ethernet
It is not too expensive to build an Ethernet network. Compared to other computer systems, it is less expensive.
The Ethernet network provides high data security as it uses data shortcuts for data security.
Also, the Gigabit network allows users to transfer data at a speed of 1-100Gbps.
In this network, the data transfer quality is maintained.
In this network, management and maintenance are easy.
The latest version of gigabit Ethernet and wireless Ethernet has the ability to transfer data at a speed of 1-100Gbps.
Ethernet malfunction
Requires decisive service; therefore, it is not considered the best of real-time applications.
The wireless Ethernet network limits you beyond distances and is best used for short distances.
When you create a wired Ethernet network that requires cables, harbors, switches, routers, it increases installation costs.
Data requires faster transfer to a compatible application, and data is much smaller.
In an Ethernet network, an acknowledgment is not sent by the recipient after receiving the package.
If you plan to set up a wireless Ethernet network, it may be difficult if you do not have experience in the network field.
Compared to a wireless Ethernet network, the wireless network is less secure.
The complete duplex data connection mode is not supported by version 100Base-T4.
Additionally, finding a problem is very difficult for an Ethernet network (if any), as it is not easy to determine which node or cable is causing the problem.
Ethernet History
In the early 1970s, Ethernet was developed several years from ALOHA net from the University of Hawaii. Then came the experiment, which culminated in a scientific paper in 1976, and was published by Metcalfe and David Boggs. Toward the end of 1977, a patent was granted by Xerox Corporation.
Ethernet as a standard was developed by Xerox, Intel, and Digital Equipment Corporation (DEC); first, these companies merged to develop Ethernet in 1979 and then published the first standard in 1980. Other technologies, including the CSMA / CD protocol, were also developed with the help of this process, later known as IEEE 802.3. This process also led to the creation of the token bus (802.4) and the token ring (802.5).
In 1983, IEEE technology became the standard, and before 802.11, 802.3 was born. Many modern PCs are beginning to integrate Ethernet cards into the motherboard, as with the introduction of single-chip Ethernet controls, the Ethernet card became more expensive. As a result, the use of Ethernet networks in the workplace was started by small companies but they are still being used with the help of four wireless four-wire-based networks
Until the early 1990s, creating an Ethernet connection with two twisted cables and fiber optic was not invented. That led to the development of the 100 MB / s standard in 1995.
