NIC stands for Network Interface Controller. Many terms describe the same device. Here, you will learn the different types of NICs and what they do. You can also find information about Ethernet and Gigabit LAN NICs. These devices are an integral part of your computer system. In addition, they allow you to connect to the internet. So, if you’re using a laptop or desktop computer, you should be familiar with these terms.
NIC
The National Informatics Centre, or NIC, is an institution in India that provides computer networking and related services. It develops application and system software, creates database systems, and establishes satellite-based computer communication networks. The organization is part of the government and is responsible for maintaining data related to various industries.
The National Informatics Centre is the topmost organization under the union government of India. It is the prime agency that uses informatics to make sure the government and other platforms operate effectively. This organization has offices in all 29 states and seven union territories.
Ethernet NIC
Ethernet NIC is a network interface card that enables computers to share large amounts of data. This computer connection is most commonly used in LAN, MAN, and WAN networks. An Ethernet NIC consists of a pair of ethernet cables. An Ethernet NIC also has jumpers that allow you to control communication operations without using any software.
This hardware device must join different computers and provide a secure connection. It also facilitates connecting external devices to a computer network. Ethernet NICs are relatively cheap and offer high-speed data transfer but require decent configuration. Moreover, a wired NIC requires a rigid wired connection.
Gigabit LAN NIC
A Gigabit Ethernet connection for a PC can deliver up to 900 Mbps of effective data transfer. However, this rate is limited by a variety of factors. These include disk drive speeds, bandwidth, and network protocol overhead. There are several ways to improve the speed of a Gigabit Ethernet connection.
Gigabit Ethernet uses the same 802.3 framing scheme as standard Ethernet but supports speeds of up to 1 Gbps. Gigabit Ethernet also uses a technology known as Carrier Sense Multiple Access (CSMA/CD) to detect collisions and handle transmissions. Because data packets may collide due to their high transmission rates, Gigabit Ethernet uses collision detection and handling to ensure data transmission is uninterrupted.
Fiber-optic LAN NIC
Fiber-optic LAN network interface cards can handle data transmission on fiber-optic lines. They can be as long as 200 kilometers and are based on the token ring protocol. This network can support thousands of clients and is commonly used in WAN and spine connections.
These cards come in two types – single-mode and multi-mode. Single-mode cards use a single-mode fiber and are commonly used in single-mode networks, while multi-mode cards use multiple light modes.
Wireless LAN NIC
Network Interface Cards (NICs) are small, computer-based devices that enable you to connect to the internet. They come in several different forms, including wireless and wired. Wireless NICs use radio waves to communicate. An antenna is usually attached to wireless NICs. Some NICs can also be called wireless LAN NICs, depending on the network standard.
A NIC works as a middleware between the computer and a network. It comprises several different components that enable it to function as a bridge between the computer and the network. The main components of a NIC include a processor and memory. It also has an Ethernet port for connecting to an Ethernet network.
