The CPU (Central Processing Unit) is the brains of the computer; it processes the instructions
of your system's programs. The CPU is also known as the processor or microprocessor and can
be found on the motherboard of your computer.
The Direct Current interface to which you connect your computer's AC adapter.
A driver is software enabling you to use hardware devices. For example, in order for you to
be able to use a printer, you must first install its driver. Many drivers, such as the mouse
driver, come with the operating system.
Short for Digital Versatile Disc. A type of read-only CD with a minimum capacity of 4.7 GB
(maximum capacity can reach 17 GB). This high storage power makes it the ideal medium for
storing films.
A rewritable DVD, based on the DVD-R format, that can be used to write, erase and rewrite
a program or other data approximately 1,000 times.
See http://www.dvdrw.com for more information on the DVD-RW.
The DVD+RW is a slightly different rewritable DVD format, backed by a group of companies
known as the DVD+RW Consortium, which includes Sony. Its advantages include high-
compatibility, high capacity and easy-to-use functionality. Like the DVD-RW, it can be
rewritten about 1,000 times. However, a DVD+RW drive writes at a higher speed than a DVD-
RW drive.

more recent version of Ethernet, called 100BASE-T, provides data transfer rates of 100 Mbps.
