In this way it is similar to DSL. The ADSL technology supports an approx downstream rate of 1.5 to 9Mbps and an upstream rate of 16 to 640Kbps.
Alt tag: A HTML tag that labels an image on a web page. These labels are especially useful for the vision impaired or those who choose not to download images. To view an 'alt tag', hover your mouse over an image on a web page for a few seconds and the alt tag should appear. Web designers are not required to include an alt tag on images, however it does improve the useability of their site.

Because it's almost universally understood by different computers and software, an ASCII file (also called a plain text file) is widely used for sharing text information or raw alphanumeric data.
Attachment/enclosure: A file sent with an email message. It could be a word processor or spreadsheet file, an image or an application. Note that these have to be "encoded" to travel over the Web. If you are having trouble reading an attachment, check that both yourself and the sender are using the same encoding methods in your email client. Also make sure that you have any software needed to read the file (you cannot read a Photoshop file unless you have Photoshop (or a program cablable or reading .psd files) installed on your computer for example).

Bandwidth: Data travels over the Internet as a stream of electronic pulses. The volume of data that can travel in a given time over a particular path on a network (in our case the Internet) is its "bandwidth". If you imagine the flow of data as a flow of water through a pipe, the bandwidth is the size of the pipe. The bigger the pipe, the more water (or data) can flow. Text and small images can be sent quite easily on low bandwidth pipes (like phone lines) whereas sound and video files require larger amounts of bandwidth to be transmitted. The bandwidth of a particular network path is limited to the "narrowest" link in the path. Bandwidth is also used to describe people's ability to deal with information. Someone with a lot of bandwidth can deal with a lot of information at once.
Baud: The 'baud rate' of a modem indicated the number of bits it can send or receive per second.
Binary File: Any file that is stored as binary numbers, the raw language of computers. Binary files will only run with the right software on the right computer.

bps: Bits Per Second. A measure of data transfer speed. Most often seen as Kbps and Mbps (Kilobits per second and Megabits per second). "k" is the digital equivalent of a thousand but, unlike metric measures where a "k" is 1,000, the "k" in digital terms means 1,024, or 2 10 . Similarly, "m" means million, but digitally, it's 1,048,576 bits, or 2 20 . So given a byte is 8 bits, a megabyte is 1,048,576 bytes or 8,388,608 bits. Ideally, a Dialup modem operates at 56 kbps whereas a Cable Modem operates at around 5000 kbps.
