Ethernet – Tutorial:

Ethernet is a type of LAN referring to local area network technology and it is the most popular today. Ethernet defines the number of conductors a connection requires and the performance thresholds likely to be attained. This type of LAN technology also provides the structure for data transmission. The standard Ethernet network is able to transmit data up to the rate of 10 megabits per second (Mbps). There are other LAN types and they include Fast Ethernet, Fiber Distributed Data Interface, 10 Gigabit Ethernet, and Gigabit Ethernet or even LocalTalk. The reason Ethernet is popular is that it creates a balance in terms of ease of installation, cost, and speed. It is the most used LAN technology for computer networking today. Although Ethernet became available in 1980, it was later in 1983 standardized as IEEE 802. The standardization later replaced other LAN technologies like Token Ring, ARCNET, and FDDI.

What Does CSMA/CD do?

When two computers try sending data simultaneously, the data may become unusable. The two computers just halt sending the data then after some time, they begin the process again. A protocol known as Carrier Sense Multiple Access or CSMA helps resolve this issue associated with data collision detection.

Ethernet Cables:

When you look at Ethernet cables, they resemble those used in telephone installations and they feed or connect to hubs or switches which are a type of box for Ethernet networking. Each cable moves from network interface card (NIC) of the computer to a box or hub. This cable is referred to as 10BaseT, 100BaseT, or say 1000BaseT cable.

Types of Ethernet Cables:

10Base2 and 10Base5:

Also known as coaxial cables, 10Base2 and 10Base5 are cables similar to the ones you find in televisions; however, these ones are a little bit thin. 10Base2 cables are designed to offer a maximum transmission rate of 10Mbps with use of baseband signal. The cable length is 100 meters with a maximum of 2 segments. With 10Base5, they are same as 10Base2 but with a continuous cable segment, not more than 100 meters every segment.

10BaseT:

This refers to Ethernet cable with the maximum transmission rate of 10Mbps on a twisting pair cabling. They are designed of copper material and go from a PC to a switch or hub.

10BaseF:

These are different from the typical 10Mbps Ethernet cables in that they use fiber-optic cabling rather than the copper unshielded twisted-pair cabling or UTP cabling. They are similar to 10BaseT cables because every station it cabled or wired into a hub made of fiber optic on a star topology where they form the network. Their maximum length goes to 2 kilometers. Instead of transmitting electrical signals, 10BaseF cables transmit light pulses.

100BaseT:

These are a type of LAN cables representing an enhanced form of 10BaseT. They are used to transmit data at speeds of 100Mbps. 100BaseT cables are 10 times faster than typical Ethernet. And, just like the standard Ethernet, they also follow the CSMA/CD technique to eliminate collision.

1000BaseT:

These are gigabit Ethernet cables made of copper and they use four pairs of unshielded twisted pair cables category 5 to attain gigabit data rates.

Today, the 1000BaseT, 100BaseT, and 10BaseT cables use unshielded twisted pair category 5 or UTP-Cat5.
