3. What is Network ?
 A network is two or more computers, or
other electronic devices, connected
together so that they can exchange data.

Types of Create
Connection
connection between three computers
or more, or three machine or more,
and join three business apartment or
more that we can exchange data.
The simplest type of connection
between two computers or two
machine or join two business
apartment that we can exchange data.

General Types of
Network
This Network used between countries
for example join countries all over the
world.
This network using in local for
example for join multi office together
or join network between cities , this
network reduce cost than Global
network.

8. Types of Network
 LAN ( Local Area Network )
 MAN ( Metropolitan Area Network )
 WAN ( Wide Area Network )
 WLAN ( Wireless Local Area Network )

9. Local Area Network
 This is one of the original
categories of network, and one of
the simplest. LAN networks
connect computers together over
relatively small distances, such as
within a single building or within a
small group of buildings, This
network used between (100m –
1000m).
9

10. Metropolitan Area Network
 This is a network which is larger
than a LAN but smaller than a
WAN, and incorporates elements
of both. It typically spans a town
or city and is owned by a single
person or company, such as a
local council or a large company.
10

11. Wide Area Network
 This is another of the original categories of
network, and slightly more complex in nature.
WAN networks connect computers together
over large physical distances, remotely
connecting them over one huge network and
allowing them to communicate even when far
apart. The Internet is a WAN, and connects
computers all around the world together.

12. Wireless Local Area Network
 This is a LAN which works using
wireless network technology such as
Wi-Fi. This type of network is
becoming more popular as wireless
technology is further developed and is
used more in the home and by small
businesses. It means devices do not
need to rely on physical cables and
wires.

13. Advantages of Network
 Easily share files and data.
 Share resources such as printers and Internet connections
 Communicate with other network users (e-mail, instant messaging, video-
conferencing, etc.).
 Store data centrally .
 Keep all of our settings centrally .

14. Disadvantages of Network
 The computer is vulnerable to hackers.
 If the network breaks, many tasks become very difficult.
 Your computer can more easily be attacked by a virus.

15. What is Network Topology ?
 This is the basic Systemize of Network to create our networks easiest
and best form,
15
 Types of Network Topology:
1- Star
2- Ring
3- Bus
4- Mesh
5- Line
6- Tree
7- Fully connected

16. What is IP Address ?
 IP is abbreviation of ( Internet Protocol ), IP consisted four parts that each
of them consist of three numbers, between each other part have a dot( . ) ,
numbers will be prolonged from ( 0 to 250 ).
For example (192.198.0.1 ) or (168.10.10.10 )
 We have Two Types of IP ( Internet Protocol ) : -
1- Dynamic IP addresses ( Temporary )
2- Static IP addresses ( Permanency )

17. Conclusion:
 As a result in this presentation we learned that Network is the main way
to exchange data ,files and information between Computers and
electronic devices of cities and countries. And we learned types of
Network ,and advantages and disadvantages of network. And we knew
ways to create connection for Network. .
And we talked about Network topology and it types, and IP address.
