Cable Modem = A cable modem is used for connecting to the Internet and is much faster than a
typical dial-up modem. While a 56K modem can receive data at about 53 Kbps, cable modems support
data transfer rates of up to 30 Mbps. That's over 500 times faster. Unfortunately, most ISPs limit their
subscribers' transfer rates to less than 6 Mbps to conserve bandwidth.

CD_ROM =Stands for "Compact Disc Read-Only Memory." A CD-ROM is a CD that can be read by a
computer with an optical drive. The "ROM" part of the term means the data on the disc is "read-only,"
or cannot altered or erased. Because of this feature and their large capacity, CD-ROMs are a great media
format for retail software. The first CD-ROMs could hold about 600 MB of data, but now they can hold
up to 700 MB. CD-ROMs share the same technology as audio CDs, but they are formatted differently,
allowing them to store many types of data.

Bandwidth = Bandwidth refers to how much data you can send through a network or modem
connection. It is usually measured in bits per second, or "bps." You can think of bandwidth as a
highway with cars travelling on it. The highway is the network connection and the cars are the data. The
wider the highway, the more cars can travel on it at one time. Therefore more cars can get to their
destinations faster. The same principle applies to computer data -- the more bandwidth, the more
information that can be transferred within a given amount of time.

Cookie = In computer terminology, a cookie is data sent to your computer by a Web server that
records your actions on a certain Web site. It's a lot like a preference file for a typical computer
program. When you visit the site after being sent the cookie, the site will load certain pages according to
the information stored in the cookie.

For example, some sites can remember information like your user name and password, so you don't
have to re-enter it each time you visit the site. Cookies are what allow you to have personalized web
sites like "My Yahoo," where you can customize what is displayed on the page. While cookies have many
benefits, some people don't like to have their information recorded by Web sites that they visit. For this
reason, most Web browsers have an option to accept or deny cookies.

Data = Computer data is information processed or stored by a computer. This information may be in
the form of text documents, images, audio clips, software programs, or other types of data. Computer
data may be processed by the computer's CPU and is stored in files and folders on the computer's hard
disk.

Dial Up = A dial-up connection uses a modem to connect to an ISP or another computer. It uses
standard analog phone lines to transfer data up to 56 Kbps. Before the year 2000, dial-up was the
standard way to connect to Internet. However, most users now connect to the Internet is via a DSL or
cable modem connection. Both cable and DSL services provide a constant connection and support data
transfer speeds over 100 times faster than dial-up modems.

Dual Core = A dual-core processor is a CPU with two processors or "execution cores" in the same
integrated circuit. Each processor has its own cache and controller, which enables it to function as
efficiently as a single processor. However, because the two processors are linked together, they can
perform operations up to twice as fast as a single processor can.

The Intel Core Duo, the AMD X2, and the dual-core PowerPC G5 are all examples of CPUs that use
dual-core technologies. These CPUs each combine two processor cores on a single silicon chip. This is
different than a "dual processor" configuration, in which two physically separate CPUs work together.

Email = It's hard to remember what our lives were like without e-mail. Ranking up there with the Web
as one of the most useful features of the Internet, e-mail has become one of today's standard means of
communication. Billions of messages are sent each year.

E-mail is part of the standard TCP/IP set of protocols. Sending messages is typically done by SMTP
(Simple Mail Transfer Protocol) and receiving messages is handled by POP3 (Post Office Protocol 3), or
IMAP (Internet Message Access Protocol).

Though e-mail was originally developed for sending simple text messages, it has become more robust
in the last few years. Now, HTML-based e-mail can use the same code as Web pages to incorporate
formatted text, colors, and images into the message. Also, documents can be attached to e-mail
messages, allowing files to be transfered via the e-mail protocol. However, since e-mail was not
originally designed to handle large file transfers, transferring large documents (over 3 MB, for example)
is not allowed by most mail servers. So remember to keep your attachments small

Firewall = A computer firewall limits the data that can pass through it and protects a networked server
or any computer from damage by unauthorized users.

Firewalls can be either hardware or software-based. A router is a good example of a hardware device
that has a built-in firewall. Most routers can be configured to limit traffic from certain IP addresses or
block requests based on other criteria. Software programs that monitor and restrict external access to a
computer or network can also serve as firewalls. A network firewall only allows authorized traffic from
the Internet to flow in and out of the network.

Internet = The Internet spreads across the globe and consists of countless networks and computers,
allowing millions of people to share information. Data that travels long distances on the Internet is
transferred on huge lines known collectively as the Internet backbone. The internet is made up of many
subsets. The world wide web, email, irc chat are just a few of theses.

WWW = World Wide Web. A sub set of the Internet that can be accessed through a web browser often
mistaken for the internet.

Download = This is the process in which data is sent to your computer. Whenever you receive
information from the Internet, you are downloading it to your computer. For example, you might have
to download an upgrade for your computer's operating system in order to play a new game. Or you
might download a demo version of a program you are thinking about buying from the software
company's Web site. The opposite of this process, sending information to another computer, is called
uploading.
