First of all, we have to be familiar with the word "Ethernet" .. WHAT IS ETHERNET?
Ethernet is a type of network cabling and signaling specifications developed by Xerox in the late 1970. While Internet is a global network, Ethernet is a local area network (LAN). No computer should be an island. With Ethernet, file sharing and printer sharing among machines became possible. The term "ether" was coined by Greek philosopher Aristotle to describe the "divine element" in the heaven. In the 17th century, French philosopher and mathematician Rene Descartes theorized that the universe has no void; all space, including the heaven and the earth, is filled with ether, which is composed of very fine particles. In short, "ether" is said to be a kind of substance that exists everywhere. Although this is a misconception, network developers still adopted the term "ether" and therefore "Ethernet" means "a network of everywhere".
Standard of Ethernet.
There are several standards of Ethernet. The most popular is 10baseT. "10" stands for signaling speed: 10 mega bits per second. "Base" stands for Baseband which uses a single frequency so that all devices connected to a network can hear the transmissions. "T" stands for twisted pair cable, 10baseT can support up to 100 meters (328 feet) of twisted pair segmet with only one tranceiver per segment.

Twisted cable for Ethernet network system
- CROSSOVER cable - this type of cabling system is intended only for two PC (connect it directly to each Ethernet port). Note: when connecting more than 2 PC, use straight-thru cable.
- STRAIGHT-THRU cable - this type of cabling system is most recommended when you design more than two PC connected all together. The first end of the cable will be connected to the PC's NIC (network interface card) and the other end is at the network device (hub or switch).
Advantages of Ethernet
- Upgradability -- there are several network protocol such as FDDI (Fiber Distributed Data Interface) which is 10x faster than 10baseT but it's 14x greater expensive than Ethernet.
- Simplicity of Installation -- it is easy to install
- Wide availability -- this is most widely use, even a MAC have already its built-in Ethernet ports and today more and more PC offer this features.
- Connectivity to the backbone -- Ethernet is a local area network protocol for different sub-network. It has an ability to connect wherever in the local area network in which all sub-networks are connected.
