What is the Ethernet network adapter?
The Ethernet network adapter is a hardware device used to connect your computer to the local network (LAN). The Ethernet network adapter, which is sometimes called a network interface card (nothing), supports Ethernet standards for high -speed nets via cables. The primary function of this device is to transmit and receive data to and from a network center, switching or router.
Most computers come with the built -in Ethernet network adapter. Those who cannot have one added. This can be done by installing the adapter card on the computer using the PCI slot on the motherboard. Another option is to connect the Ethernet network adapter using a serial or USB port of the computer.
Ethernet adapters are characterized by their data transfer speed. Today, desktop and notebook computers usually use the Ethernet or Gigabit Ethernet or Gigabit adapter. These adapters promote 100 megabits per second and 1 Gigabit per second. High -performance workstations servers usually use 1 gigaBit per second Ethernet adapters.
Each Ethernet network adapter has a connector that receives a cable that carries data. The cable connects a computer with a network hub, switch or router. The cable can be made of copper wires or cables of optical fibers; Usually, network adapters with optical optical Ethernets are used only in special cases. For example, an optical fiber adapter would be used when the cable passes through an area where there is a lot of electric interference. Optical fiber adapters are also used when the computer is very far from the hub or switch.
The Ethernet network adapter in conjunction with the network and the control software works for sending and receiving data. For outgoing data, the adapter analyzes large blocks or streams into small pieces. Then they place these small pieces of data in packets called Ethernet framework. Each frame of Ethernet Mázhalovy with information abouttinged and source address. Network devices use the network device to direct the packet on the recipient's computer.
The second part of the Ethernet frame is useful load, which is basically a small piece of raw data. The last element of the Ethernet frame is a small amount of data called the CRC control sum. The CRC control sum is used to ensure that the data is not damaged during transmission.
with incoming data adapter Ethernet Network again works with the driver and software for network. In this case, the adapter extracts the useful load data from the Ethernet incoming images.
New use of Ethernet adapters are still appearing. For example, many company telephone systems are replaced by Voice Over IP systems, where telephone calls are transmitted via a company or internet data network. VoIP at each person includes the Ethernet network adapter and the phones are connected by using using theethenet wiring instead of the telephone cable.
