1. The document discusses different types of computer networks including personal area networks (PAN), local area networks (LAN), wireless local area networks (WLAN), campus area networks (CAN), metropolitan area networks (MAN), wide area networks (WAN), enterprise private networks (EPN), and virtual private networks (VPN). 2. It defines each network type based on its size and connection method, such as PAN being the smallest and revolving around one person, LAN connecting computers within a building, and WAN connecting computers across long distances globally through the internet. 3. The key differences between network types are their size and reach, from personal electronic devices on PANs, to campuses on CAN

Learning Objectives:
After reading this Information sheet, student(s) must be able to:
1. What is a computer network?
2. What are the different network designs?
3. Describe the different network design.
Computer network refers to two or more computers that are connected with one another for
the purpose of communicating data electronically. Computers communicate with one another over
networks that are connected via wire or wireless communication methods. There are many different
types of networks, and there are many different types of network-connection methods as well. The
basic difference between these network types is their size and their method of connection.
Examples of computer network are as follows:
1. Personal Area Network (PAN)
2. Local Area Network (LAN)
3. Wireless Local Area Network (WLAN)
4. Campus Area Network (CAN)
5. Metropolitan Area Network (MAN)
1. Personal Area Network (PAN) is the smallest and most basic type of
network made up of a wireless modem, a computer or two, phones,
printers, tablets, etc., and revolves around one person in one building.
These types of networks are typically found in small offices or
residences, and are managed by one person or organization from a
single device.
2. Local Area Network (LAN) connect groups of computers and low-
voltage devices together across short distances (within a building or
between a group of two or three buildings in close proximity to each
other) to share information and resources. LANs are the most frequently discussed, most
common, one of the most original and the simplest type of networks. Using routers, LANs can
connect to wide area networks to rapidly and safely transfer data.

6. Wide Area Network (WAN)
7. Enterprise Private Network (EPN)
8. Virtual Private Network (VPN)

2. 3. Wireless Local Area Network (WLAN)
WLANs make use of wireless network technology, such as Wi-Fi
to function like a LAN,. Typically seen in the same types of
applications as LANs, these types of networks don’t require
devices that rely on physical cables to connect to the network.
4. Campus Area Network (CAN) is larger than LANs, but smaller
than metropolitan area networks (MANs,
explained below), these types of networks are typically seen in
universities, large K-12 school districts or small businesses. They can
be spread across several buildings that are fairly close to each other so
users can share resources.
5. Metropolitan Area Network (MAN) These types of networks
are larger than LANs but smaller than WANs – and incorporate
elements from both types of networks. MANs span an entire
geographic area (typically a town or city, but sometimes a
campus). Ownershi p and maintenance is handled by either a
single person or company (a local council, a large company,
etc.).
6. Wide Area Network (WAN) is slightly more complex than a LAN, a
WAN connects computers together across longer physical distances.
This allows computers and low-voltage devices to be remotely
connected to each other over one large network to communicate
even when they’re miles apart.
The Internet is the most basic example of a WAN, connecting all
computers together around the world. Because of a WAN’s vast
reach, it is typically owned and maintained by multiple administrators or the public.
7. Enterprise Private Network (EPN)
These types of networks are built and owned by businesses that
want to securely connect its various locations to share computer
resources.
8. Virtual Private Network (VPN)
By extending a private network across the Internet, a VPN lets
its users send and receive data as if their devices were connected to the private network – even
if they’re not. Through a virtual point-to-point connection, users can access a private network
remotely.
