browser
Software that searches for, displays, and downloads text, graphics,
sound, and video from the Internet. Microsoft Internet Explorer and
Netscape Navigator are two popular browsers.
buffer
A temporary storage area in memory. It acts as a holding area where
data with different transfer rates can be collected, then sent as a
steady stream to the device that processes data for permanent storage.
In CD recorders, the buffer helps to prevent buffer underruns.
buffer underrun
The inability of your computer to maintain the steady stream of data
required for CD recording. The CD recorder has an internal memory
buffer to protect against interruptions and slowdowns; however, if the
interruption is so long that the buffer is completely emptied, a buffer
underrun occurs, writing stops, and the CD can be damaged beyond
repair.
bug
A mistake in the design of computer software. Because of their
complexity, designs may have minor bugs. As soon as the
manufacturer becomes aware of the problem, modifications are made
to correct it. These modifications, called fixes or patches, can be
downloaded from the manufacturer’s Web site. If a major bug is
discovered, the manufacturer releases a new version of the software.
Visit the Compaq Web site (www.compaq.com) from time to time for
the latest information about your computer, including software
updates that you can download. And visit the manufacturer’s Web site
for any software or peripherals that you purchase for your computer.

bulletin board
An electronic notice board on the Internet where people can post
notices for others with similar interests. Professional organizations
and clubs often have bulletin boards for members to share
