1. Upstream and Downstream Bandwidth

Upstream type of Bandwidth, also called Upload Bandwidth determines the amount of data that can be sent (uploaded) to the Internet. This is very important for transmitting data and uploading files to the server.

Downstream or Download type of Bandwidth determines the amount of data that is received from the Internet. This is important for downloading the files from the Internet.

2. Basic Consumer Bandwidth, LAN Bandwidth, WAN Bandwidth solutions

Basic Consumer Internet access is most commonly provided by Dial-Up, DSL or Cable connections. Each of these types of connections allows certain amount of data to be transmitted in a fixed amount of time. For a Bandwidth rate of any of these connections check types of connections
LAN (Local Area Network) stands for a group of computers and associated devices that share a common communications line or wireless link. A local area network may have as few as two or three users (for example, in a home network) or as many as thousands of users (for example, in an FDDI network). The most widely used local area network connection technology is Ethernet. Others areToken Ring technology, FDDI and ARCNET. LAN can also use wireless technology. Bandwidth allowed in a specific LAN community depends on the type of connection technology used.

For Ethernet Bandwidth rate check types of connections

WAN (Wide Area Networks) are connections between business organizations and the outside world. A WAN may also be part of a private network that extends across multiple business locations in a city, across the country or even worldwide. Typically WAN represents LAN of the certain organization connected to the outside world. The most common WAN connection is a T1 line. In order to expand Bandwidth multiple T1 lines may be bond together. Another high bandwidth protocol for business connectivity is DS3 over fiber optic SONET service or a T3 line. One of the most popular solutions is Ethernet. Ethernet that runs on LAN can be extended to the WAN. In order to use WAN Ethernet you need to be in a building which a fiber optic cable has been run into and the carrier facilities are installed or at least you have to be near enough to get connected.
