A computer network is composed of end devices, network media, and intermediary devices connected together. The number of computers that can be connected depends on the type of network, which is classified by geographical size as a personal area network (PAN), local area network (LAN), campus area network (CAN), metropolitan area network (MAN), wide area network (WAN), wireless local area network (WLAN), or peer-to-peer network. In a client/server network, servers provide centralized services and resources to client devices, while in a peer-to-peer network all devices can act as both clients and servers sharing resources directly.
This presentation briefly describes the different types of computer networks along with their advantages and disadvantages and comparison between them.
This presentation contains and will let you know about the various types of network and devices which are being used in the daily life. These devices are used as per the requirements in Office, Educational Institution, etc. This will help you in learning easily.

Types of Computer Networks bba 1st sem.pptxPankaj Chandel
There are various types of computer networks available. We can categorize them according to their size as well as their purpose.
The size of a network should be expressed by the geographic area and number of computers, which are a part of their networks. It includes devices housed in a single room to millions of devices spread across the world.
Some of the most popular network types are:
PAN
LAN
MAN
WAN
A computer network is defined as the interconnection of two or more computers. It is done to enable the computers to communicate and share available resources.
Components of computer network
Network benefits
Disadvantages of computer network
Classification by their geographical area
Network classification by their component role
Types of servers

2137ad Merindol Colony Interiors where refugee try to build a seemengly norm...luforfor
This are the interiors of the Merindol Colony in 2137ad after the Climate Change Collapse and the Apocalipse Wars. Merindol is a small Colony in the Italian Alps where there are around 4000 humans. The Colony values mainly around meritocracy and selection by effort.
2137ad - Characters that live in Merindol and are at the center of main storiesluforfor
Kurgan is a russian expatriate that is secretly in love with Sonia Contado. Henry is a british soldier that took refuge in Merindol Colony in 2137ad. He is the lover of Sonia Contado.
Hadj Ounis's most notable work is his sculpture titled "Metamorphosis." This piece showcases Ounis's mastery of form and texture, as he seamlessly combines metal and wood to create a dynamic and visually striking composition. The juxtaposition of the two materials creates a sense of tension and harmony, inviting viewers to contemplate the relationship between nature and industry.
9. Types of Network According to Geographical
Size
PAN (Personal Area Network)
LAN (Local Area Network)
CAN (Campus Area Network)
MAN (Metropolitan Area Network)
WAN (Wide Area Network)
WLAN (Wireless Local Area Network)
10. PAN (Personal
Area Network)
• A personal area network (PAN) is a
computer network for interconnecting
electronic devices centered on an
individual person's workspace. A PAN
provides data transmission among
devices such as computers,
smartphones, tablets and personal
digital assistants. PANs can be used for
communication among the personal
devices themselves, or for connecting
to a higher level network and the
Internet where one master device takes
up the role as gateway. A PAN may be
wireless or carried over wired
interfaces such as USB.
11. LAN (Local Area Network)
• is a network in which computers are relatively close together, such as within
the same office or building.
12. CAN (Campus Area Network)
• A campus area network (CAN) is
made up of an interconnection of
LANs within a limited
geographical area. The networking
equipment (switches, routers) and
transmission media (optical fiber,
copper plant, Cat5 cabling, etc.)
13. MAN (Metropolitan Area Network)
• is a network that’s smaller than a typical WAN but larger than a LAN.
• Typically, a MAN connects two or more LANs that are within the same city but are far
enough apart that the networks can’t be connected using a simple cable or wireless
connection.
14. WAN (Wide Area Network)
• is a network that spans a large geographic territory, such as an entire city or
region, or even an entire country. WANs are typically used to connect two or
more LANs that are relatively far apart.
16. WLAN (Wireless Local Area Network)
• a LAN based on WiFi wireless network technology
17. Intranet and Internet Specifications
• • Intranet: An intranet is a private network that is contained within an enterprise. It
may consist of many interlinked local area networks and also use leased lines in the
wide area network. • An intranet uses TCP/IP, HTTP, and other Internet protocols
and in general looks like a private version of the Internet. With tunneling,
companies can send private messages through the public network, using the public
network with special encryption/decryption and other security safeguards to
connect one part of their intranet to another.
• • Internet: is a worldwide system of computer networks - a network of networks in
which users at any one computer can, if they have permission, get information from
any other computer (and sometimes talk directly to users at other computers).
18. Client and Server
computer role in
networking
A network server is a computer
designed to act as central repository
and help in providing various resources
like hardware access, disk space, printer
access, etc,. to other computers in the
network.
A network server might not differ from
a workstation in hardware, but the
functionality it performs clearly
differentiates it from other
workstations. Network servers helps in
simplifying the different tasks for
system administrators including those
centering around management.
Any configuration or security updates
can be applied to a network server
instead of individually passing to
different computers connected to the
network.
19. Client and Server
computer role in
networking
A Client is a piece of computer
hardware or software that accesses
a service made available by a
server as part of the client–server
model of computer network
Client computers normally
request and receive information
over the network client. Client
computers also depends primarily
on the central server for
processing activities
20. Peer-to peer network
• A peer-to-peer network is a network where the
computers act as both workstations and servers.
• great for small, simple, and inexpensive networks.
• In a strict peer-to-peer networking setup, every
computer is an equal, a peer in the network.
• Each machine can have resources that are shared
with any other machine.
• There is no assigned role for any particular device,
and each of the devices usually runs similar
software. Any device can and will send requests to
any other
21. Client/Server
Networking
In this design, a small number of
computers are designated as
centralized servers and given the task
of providing services to a larger
number of user machines called clients
