What Are the Different Types of Computer Network and Network Types in Computers?

A computer networks is a group of computers and other devices that are connected so they can share information and resources like files, printers, or internet. These computers can be connected with wires or without wires (wireless). We use both hardware and software to make the network work.

There are different types of network in computer systems, and each type of computer network is made for a certain use, depending on the size and how far the computers are from each other.

Types of Computer Network

There are five main types of network in computer network systems:

1. Personal Area Network (PAN)
2. Local Area Network (LAN)
3. Campus Area Network (CAN)
4. Metropolitan Area Network (MAN)
5. Wide Area Network (WAN)

Let’s discuss each in detail!

1. Personal Area Network (PAN)

A Personal Area Network (PAN) is the smallest type of computer network. It connects devices around one person. You might already use it every day! For example, when your phone connects to your wireless earbuds, that’s a PAN.

This type of network connects devices like:

• Phones
• Tablets
• Laptops
• Smartwatches
• Printers

Features:

• Range: 1 to 100 meters
• Speed: Very fast
• Cost: Very low
• Used technologies: Bluetooth, IrDA, Zigbee

Types of PAN:

• Wired PAN: Uses cables like USB.
• Wireless PAN: Uses wireless tech like Bluetooth or Wi-Fi.

Why PAN is useful:

• Easy to set up and use
• Cheap and portable
• Doesn’t need much technical skill
• Great for personal use

2. Local Area Network (LAN)

A Local Area Network (LAN) is a very common type of network. It connects computers in a small area like a house, school, or office. If you’ve ever used Wi-Fi in a classroom or at home, you’ve used a LAN.

Features:

• Range: Up to 2 kilometers
• Speed: Very high
• Cost: Low
• Used technologies: Ethernet, Wi-Fi

Where we use LAN:

• Homes
• Schools
• Libraries
• Offices

Why LAN is helpful:

• Fast data transfer
• Private and secure
• Works with cables or wireless
• Easy to install and grow

3. Campus Area Network (CAN)

A Campus Area Network (CAN) is larger than a LAN but smaller than a MAN. It is used for connectivity for several buildings in a school or college campus. It is ideal for connecting a variety of departments in one location.

Features:

• Range: 1 to 5 kilometers
• Speed: High
• Cost: Medium
• Used technology: Ethernet

Where we use CAN:

• Colleges
• Universities
• Schools
• Campus offices

Why CAN is useful:

• Fast data sharing between buildings
• More secure since it’s managed by campus staff
• Cost-effective for large areas with many users

4. Metropolitan Area Network (MAN)

A Metropolitan Area Network (MAN) connects computers across a city or large town. It is larger than the Local Area Network (LAN) and Campus Area Network (CAN) but smaller than the Wide Area Network (WAN). A MAN might be used by several businesses, government buildings, or schools in different areas of a city to communicate with one another.

Features:

• Range: 5 to 50 kilometers
• Speed: Medium
• Cost: High
• Used technologies: FDDI, CDDI, ATM

Where we use MAN:

• Cities
• Large towns
• Multiple office buildings

Why MAN is helpful:

• High-speed internet across a city
• Good for many users
• Safer than WAN
• Easy to manage from one place

5. Wide Area Network (WAN)

A Wide Area Network (WAN) is the largest of all computer networks. WANs connect computers over very long distances, and sometimes internationally, that means literally across the world! The internet is the best-known example of a WAN.

Features:

• Range: More than 50 kilometers
• Speed: Low compared to LAN or MAN
• Cost: Very high
• Used technologies: Leased lines, Dial-up

Where we use WAN:

• Across countries
• Between branch offices
• In big global companies

Why WAN is important:

• Provides the ability to communicate and connect with individuals in remote areas.
• Able to store your data in one area and allow others to access it from anywhere.
• Helps businesses work in many locations
• Reduces travel and saves time

Why Should We Know the Types of Computer Network?

It’s essential to know the types of network in computer systems. Each type of computer network is optimal for specific circumstances. A PAN is optimal for personal usage, a WAN  is best for big businesses around the world. Knowing the difference helps you choose the right one for your home or workplace.

Also, when there’s a network problem, it’s easier to fix if you know which type of network you’re dealing with.

As technology grows, computer networks are becoming more important in our lives. Whether you’re watching a video, working online, or sending files, you’re using one of these types of network in computer systems.
