2. Networking
Computer network A collection of computing devices that are connected in various ways in order to communicate and share resources
Usually, the connections between computers in a network are made using physical wires or cables
However, some connections are wireless, using radio waves or infrared signals

3. Networking
The generic term node or host refers to any device on a network
Data transfer rate The speed with which data is moved from one place on a network to another
by : jigar M. Pandya

4. Client Server
Computer networks have opened up an entire frontier in the world of computing called the client/server model
by : jigar M. Pandya

5. Servers
File server A computer that stores and manages files for multiple users on a network
Web server A computer dedicated to responding to requests (from the browser client) for web pages

6. Types of Networks
Local-area network (LAN) A network that connects a relatively small number of machines in a relatively close geographical area
by : jigar M. Pandya

7. LAN
Various configurations, called topologies, have been used to administer LANs
Ring topology A configuration that connects all nodes in a closed loop on which messages travel in one direction
Star topology A configuration that centers around one node to which all others are connected and through which all messages are sent
Bus topology All nodes are connected to a single communication line that carries messages in both directions

9. Types of Networks
Metropolitan-area network (MAN) The communication infrastructures that have been developed in and around large cities
by : jigar M. Pandya

10. Types of Networks
Wide-area network (WAN) A network that connects two or more local-area networks over a potentially large geographic distance
Communication between networks is called internetworking
The Internet, as we know it today, is essentially the ultimate wide-area network, spanning the entire globe

11. Comparison Of LAN,MAN,WAN

12. So, who owns the Internet?
Well, nobody does. No single person or company owns the Internet or even controls it entirely. As a wide-area network, it is made up of many smaller networks. These smaller networks are often owned and managed by a person or organization. The Internet, then, is really defined by how connections can be made between these networks.

13. WLAN
Wireless Local Area Network
by : jigar M. Pandya

14. WLAN benefits Flexibility Installation on difficult-to-wire areas
increases working efficiency and productivity
extends the On-line period
Installation on difficult-to-wire areas
inside buildings
road crossings
Increased reliability
Note: Pay attention to security!
Reduced installation time
cabling time and convenient to users and difficult-to-wire cases
by : jigar M. Pandya

15. WLAN implementation problems
Lack of wireless networking experience for most IT engineer
Weak security policy
As a result, your WLAN may have
Poor performance (coverage, throughput, capacity, security)
Unstable service
Customer dissatisfaction

16. Campus Area Network (corporate area network (CAN).)
Campus Area Networks are usually a connection of many small LAN networks which are often used on university campuses and office buildings. Campus Area Networks allow for easy file sharing between different departments as all the files are usually shared on the server machines of each LAN network. This type of network offers a lot of simplicity in the transfer and downloading of files.

17. CAN

18. CAN CAN benefits are as follows: Cost-effective
Multidepartment network access
Single shared data
by : jigar M. Pandya

19. Storage Area Network
Storage Area Networks are primarily used as information databases. They are not usually used by large organizations  or similar entities. They are specifically used for the storage of information, and easy retrieval of specific pieces of data whenever required. Storage Area Networks are usually used by websites which offer downloading services.
