Types of computer network Doesn’t Have To Be Hard | Read it

a computer network is a word people use when they’re talking about connecting computers together so they can share data and all connect to the internet at the same time.

Networking key components that make up a simple easy to setup network think of a network as something similar to your body’s central nervous system at the top of the network is a brain.

That handles all the traffic coming through this is called a router a router the brain is connected to a spine that sends signals throughout your network this device is A switch is called and it distributes signals to all your computers and devices through network cables.

What is a router?

The router is nothing more than a fancy PC and I say fancy PC because this router has all the general components of a PC it has a processor it memory it has storage space like a hard drive or flash drive it has a network interface card on them a router has more than one network interface card

On it, almost all routers will have at least two network interface cards if not more the equipment that I got to work with when I was at the hospital as a network engineer.

Some of our routers there had hundreds of interfaces and we had hundreds of those devices so in data networking the router can have lots and lots and lots of network interface cards, either way, it’s still behaving very similar to a pc

Check out each of these components of a wired network.

The router has a smart little computer inside that identifies all of the computers and devices on your network and assigns a unique number to each one.

It is also called an IP address a router also connects to the internet outside your home via a modem that can be provided by your DSL or cable internet provider a router is always at work managing the tons of information your computers and devices send and receive and controlling which computers and devices get what information and win.

How does a send information from the internet to your computers?

The answer lies with that device we mentioned earlier switch a switch sends traffic through your networks to the places it needs to go every Netgear home router has a switch with four parts built right into it you can also get wireless routers from Netgear that use radio signals to do the same thing as a switch.

But these still have these four ports built into them so you can use wires with them too when you’re buying a router for use in a wired network pay attention to the speed of the built-in switch the fastest switches are called gigabit and they’re perfect for an application like streaming videos in your home.

Meanwhile, routers with switches called fast Ethernet are great for essential tasks like web surfing email and online gaming now say you have more than four items you’d like to plug into a router you need more ports.

A solution is easy you’ll need an additional switch which again is that thing that’s already built into your router in this case though you just need the switch portion and not another router because your network doesn’t need two routers after all.

Devices and how does it enable your computers to share information.

Netgear has switched with as few as five ports as well as some that feature 24 ports or more once again if you need the fastest speeds to go for a gigabit switch your smartypants Netgear router will recognize these new connections start sending data to them right away.

One more thing some people often confuse a switch with a related device called a hub which obsoletes you just need to know that hubs were replaced by switches because switches do the same thing but by a lot more speed and smarts.

The router a switch and network cables all come together to create a fast and reliable wired network that works a lot like your body’s nervous system fortunately I hope you understand how it all works.

Types of computer network

  • Network types depend on how big they are and how much area they cover geographically.
  • Now, most people who have a basic knowledge of networking are familiar with terms such as LAN and WAN.
  • But apart from those, there are some other network types that a lot of people are not familiar with.

Personal area network (PAN)

Now, it is a type of network that is used at the individual level. It is a small network used to connect devices such as smartphones, tablets, and laptops. And they connect using wireless technologies such as Bluetooth, infrared, and close communication or NFC.

But also connect by using a wired connection such as a USB cable.PAN is commonly used to transfer small files such as music photos, calendar appointments, etc.

Local area network (LAN)

A local area network is a group of devices such as computers, servers, switches, and printers that are located in the same building, such as in an office or a home.

In the words, close to each other, the most common type of LAN is an Ethernet LAN, where two or more computers are connected to Ethernet cables using a switch.

Wireless local area network (WLAN)


A wireless local area network is a local area network that uses wireless communication instead of wired communication. A wireless LAN is defined as at least two devices that use wireless communications to create local area networks.

A wireless LAN will typically have a Wi-Fi router or wireless access point for wireless devices such as laptops, tablets, wireless desktops, and smartphones, to communicate. So in simple terms, a wireless LAN is a LAN but without using a cable.

Campus area network (CAN)

A CAN is a network that connects two or more LANs in a limited area. CAN is a university that has multiple buildings in the same general area that are interconnected to form a larger network.

Therefore these buildings can have separate departments on the property of the university, each of which will have its LAN in its department. And then the building area is connected to form a campus area network.

Metropolitan area network (MAN)

Now, it is a larger network than CAN. It is a network that spans multiple buildings in a city or city MAN, typically connected using high-speed connections such as fiber optic cable. It is a high-speed network that gives the ability to share data and resources within the city.

Strong area network (SAN)

The SAN is a specialized high-speed network that stores and accesses large amounts of data. What is a SAN, is a dedicated network that is used for data storage. This network consists of multiple data storage.

This network consists of several disk arrays, switches, and servers. One of the main reasons for using a SAM is because SANs are not affected by network traffic such as bottlenecks that can happen in a local area network and because SANs are not part of a local area network, it has automatically partitioned a network.

Wide area network (WAN)


WAN is the largest type of network. WAN consists of multiple LANs, CAN, and MAN and is a network that is spread over a large geographical area such as a country. Continent or even the entire globe. A good example of that’s wide area network is the internet.

Advantages of computer network computer in the network

  • Computers network computers in the network can share hardware devices like printers, scanners, etc.
  • Computers in the network can share data files stored in the file server
  • Computers in the network can run the software installed in the file server.
  • Network users can exchange messages instantly.

Disadvantages of computer network

  • Data and information can be stolen by computer hackers.
  • If any computer is affected by the virus, there is a chance of spreading the virus to other computers.
  • Cables and file servers increase the cost of setting up a network.
  • The network stops working if the server breaks down.
  • Network managers and technicians are needed to run a large network.
