Networks
• a system of interconnected computers
Local Area Network
(LAN) or Intranet
Local Area Networks connect computers together that
are in a small geographical area (such as James
Workman Middle School).
A LAN is an Intranet
•
Intranet isn't a misspelling of Internet. The
prefix "intra-" is Latin for "within." An intranet
works exactly like the Internet, except it's a
network confined within a company, school,
government or organization.
Wide Area Network
(WAN)
Wide Area Networks connect Local Area Networks
(such as all the school networks in PSUSD) into a
large network of computers.
The Internet
• a global system of interconnected
networks
Modem
•
Modem stands for “modulator-demodulator”
and allows one computer to connect to
another computer and transfer data. In order
for devices on a network to connect to the
Internet, the router must be connected to a
modem.
Router
• A router is a small box that allows
multiple computers to join the
same network. Connecting to a
router provides access to a local
area network (LAN).
Internet Service
Provider (ISP)
•
To connect to the Internet, you need an
Internet Service Provider or ISP. It is the
company that your parents pay a monthly fee
to in order to use the Internet. Some ISPs are
AT&T, Earthlink, Verizon, RoadRunner,
NetZero, Cable, etc...
Extensions
•
•
•
A filename extension is located at the end of the
main filename and separated from the main
filename by a dot or space and indicates the
encoding or file format of the file.
Some examples of filename extensions are: .png,
.jpeg, .gif, .txt, .fla, .swf, .doc, .mp3, .m4v, .zip
It’s important to leave the file extension on the
filename! It tells the computer which program or
application to use to open the file.
