A subscription to an ISP (Internet Service Provider): It is also called Internet Service
Provider (ISP): an organization that provides consumers with an access to the Internet

connection.

In this unit, I learned...
 A computer network allows users to multi-play games also to communicate, to exchange
information, to chat with each other and to share software and hardware resources.
 The mother wants to have the control over her family and she wants to know what they
are doing with their computers.
 More than that, she wants to be connected to her office so she could exchange documents
with her colleagues in order to correct the mistakes and to track changes.
Types of networks based on physical scope:
Common types of computer networks may be identified by their scale. E.g.:
A wide area network (WAN) is a
computer network that covers a large
geographic area such as a city, country, or
spans even intercontinental distances…
A Metropolitan area network (MAN) is a large
computer network that usually spans a city or
a large campus.
A local area network (LAN) is a network that
connects computers and devices in a limited
geographical area such as home, school,
computer laboratory, office building, or
closely positioned group of buildings.
 The computer network is two or more computers connected between them.
 Internet called also, network of networks, is the all computer resources linked
in metropolitan geographic area (A worldwide network).
 The web is one of Internet services. It’s constituted of web pages containing
text, images sound and video. These pages linked by hyperlinks.
 Every web page is identified by web address. A web address ( or URL
address) can have the following form:
http:/www.Computer_name/Folder/File_name.html
 The surfing on the web and the research of data can be:
 By address
 By search engine
 It’s possible to import texts and images from the web in order to use them off
line.
