Types of Computer Networks
Every computer connects to the Internet or to one another through a Metropolitan Area Network, a Wide Area Network or a Local Area Network. Each different kind of network provides a different purpose, allowing people to connect computers locally, such as with LAN, or to outside networks, as with WAN. The difference between the three is the title change, however, each network is linked together by the Internet connection allowing each network to communicate information.
The speed of a network depends on the type of Internet configuration standard the Ethernet system is making use of. When the Ethernet standard was built, it was capable of transferring information at speeds of 3 Mbps across networks. When Gigabit Ethernet was made 3 years after the original Ethernet Internet, the speeds of a 1 Gigabit Ethernet standard allowed computer systems to convey data faster and more efficiently. However, these faster speeds would mean newer technology was needed to keep up with the higher speeds.
Causes of Faster Speeds
Since speeds were quicker, networks had to transfer all the data at a faster rate without losing any of the data and without slowing down the transfer rate. The digital communication roads which these networks conveyed data across had to keep up with the rate at which data was transferred. To keep up with the transfer rates, Ethernet networks started to use fiber optics to send data across networks, allowing for more efficient data transfers. Capable of sending data over longer distances and without the risk of losing data, fiber optic systems were the preferred choice. Providing the needed highway for sending data across long distances, fiber optic networks were liked, even though they were more costly.
As with the quicker speeds and differing wiring of systems, networks relied on optical transceivers to convey and receive information produced by computers at quicker speeds. Transceivers played an important role: they provided aid for copper and fiber optic networks, allowing systems to make use of both kinds of configuration modes. Older transceivers were bigger and only provided support for one wiring system, such as Gigabit Transceivers that were larger than newer SFP modules, such as Cisco SFP modules. Compared to their older variations, the newer transceivers were smaller, better, and capable of offering support for the different Ethernet configurations and distances.
