(1) 10-Mbps Ethernet,
10BASE5 (also known as thick ethernet or thicknet) was the original commercially available variant of Ethernet
For its physical layer it used cable similar to RG-8/U coaxial cable but with extra braided shielding
Disadvantages
Adding new stations to network was complicated by the need to accurately pierce the cable. The cable was stiff and difficult to bend around corners. One improper connection could take down the whole network and finding the source of the trouble was difficult.
(2) 100-Mbps or Fast Ethernet(Fast Ethernet is sometimes referred to as 100BASE-X where X is a placeholder for the FX and TX variants),
The 100 in the media type designation refers to the transmission speed of 100 Mbit/s. The "BASE" refers to baseband signalling. The TX, FX and T4 refer to the physical medium that carries the signal
100BASE-TX is the predominant form of Fast Ethernet, and runs over two wire-pairs inside a category 5 or above cable.
Like 10BASE-T, the active pairs in a standard connection are terminated on pins 1, 2, 3 and 6. Since a typical category 5 cable contains 4 pairs, it can support two 100BASE-TX links with a wiring adaptor.
Each network segment can have a maximum cabling distance of 100 metres (328 ft).
In its typical configuration, 100BASE-TX uses one pair of twisted wires in each direction, providing 100 Mbit/s of throughput in each direction (full-duplex).
(3) 1000-Mbps or Gigabit Ethernet gigabit Ethernet (GbE or 1 GigE) is a term describing various technologies for transmitting Ethernet frames at a rate of a gigabit per second (1,000,000,000 bits per second)
Half-duplex gigabit links connected through hubs are allowed by the specification,[1] but full-duplex usage with switches is much more common.
