5) Click on “save “button to validate.

Observation1: Surfing on the web and the research of data can be:

By address: if you know the website URL

By search engine: if you don’t know where to find the information than youwould rather use a search engine to search for possible links which can lead youto the right webpage which contains the information you look for.

Observation2: We can collect information from:

-books, news papers, magazines;

-other people: teachers, elders, mentors, encyclopedic scientist…

-TV; Radio; etc.

Today, thanks to the technological development there’s another source of information

which is Internet by surfing the web.

Internet and the Web?


The Web or the WWW an Internet service , one of the many services that Internet

provides like the e-mail, the chat, the videoconferencing, the social networking, the

File Transfer , etc.

Internet


The right hardware

a. A powerful computer with at least 8 megabytes (MB) of RAM and10 MB of free disk space.

b. A Modem (external)or (modem card internal device):is an electronic device that connects computers and identify the data being sentand received. (go back to the first unit).

c. A telephone line or a satellite transmission or any othertelecommunication system.

Wires, cables, optical fibers, satellite transmission are physical links ≠hyperlinks are abstract links between web pages and websites


A Browser: Is an application program used to display information located in theweb.A subscription to an ISP (Internet Service Provider): It is also called Internet Service

What is a computer network?

* Terminals, and communication devices: iPad; i phone; smart phones; e-book; PSP;…

**wires, cables, or a telecommunication system: are means of connection through wires or wirelessconnection.

A computer network allows also sharing software resources like files, folders, programs; toconsult them or make modifications.

• The son wants to remote play games with his sister each one from his own room.

Task 5: Complete the following definition with words from this list:information, exchange, computers, connected, communicate, wires, share

A computer network is a system of two or more ………………, terminals, and

communication devices* linked (……………..) by …………, cables, or a

telecommunication system** in order to …………….. software resources (data, files,

programs, applications) or hardware resources (printer or scanner, etc) and

…………………….information. It allows computers to ……………………. with each other.


























In this unit, I learned...

A computer network allows users to multi-play games also to communicate, to exchangeinformation, 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 theyare doing with their computers.

More than that, she wants to be connected to her office so she could exchange documentswith 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 acomputer network that covers a largegeographic area such as a city, country, orspans 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 linkedin metropolitan geographic area (A worldwide network).

The web is one of Internet services. It’s constituted of web pages containingtext, images sound and video. These pages linked by hyperlinks.

Every web page is identified by web address. A web address ( or URLaddress) 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 offline.
