1 Define network
According to (computerhope.com, 2021), a network is a collection of computers, servers,
mainframes, network devices, peripherals, and other pieces of hardware together to share data. The
Internet, for example, is a network that links millions of users worldwide. An example of a home
network with numerous PCs and other access points is shown to the right.
A network is mainly of four types:
o LAN (Local Area Network)
o PAN (Personal Area Network)
o MAN (Metropolitan Area Network)
o WAN (Wide Area Network)
2 Types of network
2.1 LAN (Local Area Network)
 A local area network (LAN) is a collection of computers connected in a limited area, or by a
building or an office.
 A local area network (LAN) connects two or more computers using a channel such as
twisted pair or coaxial cable.
 That's less expensive since it is made up of low-cost components such as hubs, storage
devices, and ethernet cables.
 In a Local Area Network, data is transmitted at an incredibly rapid rate.
 A higher level of security is provided by a Local Area Network.
6

 Advantages of LAN:
 Resource Sharing: A LAN allows computer resources such as printers, scanners,
modems, DVD-ROM drives, and hard drives to be shared across connected devices.
This lowers the cost of hardware and lowers the amount of money spent on it.
 Software Application Sharing: Systems acquiring differently licensed technology for
each client on a network, it is simple to use technology on several computers linked to
the network.
 Communication is simple and inexpensive: Data and messages may be readily shared
with other computers on the network.
 Data Can Be Centralized: The data of all network users can be saved on the
central/server computer's hard disk. This allows users to access data from any computer
on the network.
 Data Security: Because data is kept on the server computer, it will be easier to handle
data from a single location while also being more secure.
 Internet Sharing: A Local Area Network (LAN) allows all LAN users to share a local
network. A single web server is used to deliver the internet to all linked computers in
school laboratories and internet cafes.
7

 Disadvantages of LAN:
 Internet Sharing: A Local Area Network (LAN) allows all LAN users to share a local
network. A single web server is used to deliver the internet to all linked computers in
classrooms and internet cafes.
 Privacy Infringements: The LAN administrator has access to each LAN user's data files
and can inspect them. He may also view the LAN user's PC and internet history.
 Unauthorized users can get access to sensitive data at an office or campus if the LAN
administrator fails to properly safeguard a server hard drive.
 LAN Administrator Job: A LAN Administrator is required because issues such as
software installs, program errors, data loss, and cable disruptions occur in the Local Area
Network. These difficulties demand the attention of a LAN Administrator.
 LANs are limited in size; they can only cover a small region, such as a single office, a
new location, or a group of neighboring buildings.
2.2 PAN (Personal Area Network)
 A Personal Area Network (PAN) is a network that is set up within a single person and
generally has a total of 15 meters.
 The term "Personal Area Network" refers to a network that is used to link personal
computing devices.
 The Personal Area Network was initially proposed by Thomas Zimmerman, a researcher.
 The Personal Area Network (PAN) spans a 30 feet radius.
 Laptops, mobile phones, media players, and play stations are key traits smart devices that
are utilized to build a personal area network.
8

There are two types of Personal Area Network:
 Wired Personal Area Network.
 Wireless Personal Area Network.
 Wireless Personal Area Network: Wireless Personal Area Networks (WPANs) are created
by combining wireless technologies like WiFi and Bluetooth. It's a network with a short
range.
 Wired Personal Area Network: The USB is used to establish a wired Personal Area
Network.
 Advantages of PAN:
 There is no need for more space: A personal area network does not necessitate the use of
additional wiring or space. To link two devices, all you have to do is turn on Bluetooth
on both devices and start sharing data. Connecting a wireless keyboard and mouse to a
tablet through Bluetooth, for example.
 Connect to several devices at once: In a personal area network, multiple devices can be
linked to one device at the same time. To share files, you can link one phone to several
additional phones or tablets.
 Cost effective: This sort of network does not require any more cables. PAN is also a
cost-effective mode of communication because there are no additional data charges.
 Simple to use: It is simple to use. There is no need for a complicated setup.
 The network is robust and dependable if you utilize this sort of data connection within
10 meters.
 This network is safe because all devices must be approved before data can be shared. In
PAN, data hacking and third-party injection are not feasible.
 Infrared is a technology that is utilized in TV remotes, AC remotes, and other devices in
the office, conference, and meetings. Digital gadgets at workplaces, meetings and
conferences are connected via Bluetooth, infrared, and other forms of PAN.
 Data synchronization across devices: A single individual may synchronize several
devices, including downloading, uploading, and share information.
 Because it is a wireless network, users may move their devices around without affecting
data transfer. As a result, PAN is also transportable.
9

 Disadvantages of personal area network:
 The signal range is limited to a maximum of 10 meters, which makes long-distance
sharing difficult.
 Interfere with radio communications: Because personal area networks employ infrared,
they can interfere with radio signals, resulting in data loss.
 Sluggish data transfer: When compared to other types of networks, such as LANs,
Wireless and infrared get a slow data transfer rate (local area network).
 PAN employs microwave frequencies in various digital devices, which can harm the
human body, such as causing brain and heart issues.
 PAN is expensive in terms of communication equipment since it is utilized in digital
gadgets, which are expensive. This is another drawback of PAN. Smartphones, PDAs,
computers, and digital cameras are just a few examples.
 Infrared signals move in a straight path: Television remote controls employ infrared
signals, which have the drawback of traveling in a straight line. As a result, this is
another drawback of PAN.e in PAN.
Personal Area Network (PAN) Examples:
 Body Area Network: A network that travels with a person is known as a body area network.
A mobile network, for example, follows a person. Assume a person makes a network
connection and then establishes a connection with another device to transfer data.
 Offline Network: An offline network, often known as a home network, can be built within
the home. The purpose of a home network is to link devices such as printers, computers, and
televisions that are not wired.
 Small Home Office: It connects a range of internet-enabled devices and to a business
network via a virtual private network (VPN).
2.3 MAN (Metropolitan Area Network)
 A metropolitan area network (MAN) is a network that connects many LANs to build a
bigger network that spans a wider geographic region.
 MAN is used by government organizations to communicate with individuals and private
businesses.
 MAN connects several LANs via a central office line.
 RS-232, Frame Relay, ATM, ISDN, OC-3, ADSL, and other protocols are often used in
MAN.
 Its range is greater than that of a Local Area Network (LAN).
