These days, computer networks play a crucial role in our technologies. Whether it is through homes, Schools, Offices, Banks, Hospitals or large companies Networking makes the devices communicate and exchange data. A network is the ability to connect computers, smartphones, storage devices, servers and printers with one another to exchange data.
On the other hand, not every network is meant for use at a particular place. The coverage area of networks varies from small areas to devices across cities, countries or the world. If they are aware of the network types, then it would be easier for students and beginners to understand computer networking while providing them with the knowledge necessary to build a solid foundation.
This guide will discuss the most common types of computer networks you can expect to see today for each category, what they are used for, and their major benefits — all in easy-to-understand language.
What Is a Computer Network?
Computer Network: — A computer network is a collection of systems that communicate with one another & utilise resources mutually. Such devices may be computers, mobile phones, servers, printers, routers and other networking hardware.
Wired technologies like Ethernet cables or wireless technologies like Wi-Fi can join networks.
A network has the following primary objectives:
- Sharing files and information
- Sharing hardware such as printers
- Accessing applications and services
- Communicating between devices
- Sharing an internet connection
- Managing data efficiently
The type is largely dependent upon the size and purpose of a network.
WHY DO WE NEED DIFFERENT NETWORK TYPES?
Networking requirements vary by the organization or environment. A home can be designed as smaller, requiring the simplest localised network and systems whereas a multinational company may require a protracted routing connecting offices in multiple countries.
Network classes are usually classified based on the factors:
- Geographic coverage
- Number of connected devices
- Purpose of the network
- Communication technology
- Ownership and management
Knowing these nuances leaves you to understand modern communication systems better.
Personal Area Network (PAN)
A PAN or Personal Area Network is a small network that covers devices owned by a single individual.
Like your smartphone when you connect wireless earphones, a smartwatch or a laptop to it – all of these are examples of a personal network.
Typically, PANs have a very short range and may utilize technologies like Bluetooth or USB.
Common Uses of PAN
- Connecting smartphones and smartwatches
- Connecting wireless headphones
- Sharing data between personal devices
- Connection of computer with peripheral devices
PANs: PANs are very basic and easy for use purposes in day to day life.
Local Area Network (LAN)
Another type is Local Area Network also called as LAN and it connects the devices within a limited geographical area.
LANs are widely used in homes, schools, offices, computer laboratories and small businesses.
For example, computers in an office may be connected to the same network so they can share files, printers, applications and internet access.
A LAN can be wired or wireless. We generally use the Ethernet for wired connection and Wi-Fi is used as a wireless LAN.
Benefits of LAN
- Fast communication
- Resource sharing
- Easy management
- File sharing
- Shared internet access
- Suitable for homes and offices
LAN is one of the most frequently used network types.
Metropolitan Area Network (MAN)
Metropolitan Area Network (MAN) As the name suggests, unlike LAN, a MAN is larger in size but smaller than Wide Area Network.
A MAN generally includes one city or a big metropolitan location. It can link various offices, educational institutions, and government buildings or facilities in a particular region.
Metropolitan Area Network- As the name suggests this network is used an organization having multiple branches in a specific city to connect the locations of this organization.
Over the normal LANs, more infrastructure is needed; hence a MAN will typically be owned by a corporation, service provider, or institution.
Wide Area Network (WAN)
WAN or Wide Area Network is a nework that covers larger geographical area. It has the power to connect devices and networks on a city, state, country, or continent-wide scale.
The Internet is the most widely recognized illustration of an overall system climate.
Organisations with offices in multiple cities or countries may use WAN technology to tie site locations together.
Features of WAN
- Covers large geographical areas
- Connects multiple LANs
- Can use leased communication links
- Supports communication between distant locations
- Useful for multinational organizations
Wide Area Network (WAN) — WANs are required for businesses to connect different locations that may be far apart and facilitate data sharing between local offices.
Wireless Local Area Network (WLAN)
Thus, a Wireless Local Area Network uses wireless communication like LAN but mainly does not support on physical network cables.
Examples of this wireless local area network include Wi-Fi networks at homes, schools, offices, hotels and public locations.
WLANs are comfortable and flexible which is the main benefit of using WLAN. This ability to move around in an area of the coverage range without being connected by a physical ethernet cable.
Advantages of WLAN
- Easy installation
- Mobility
- Reduced cabling
- Convenient device connection
- Suitable for modern workplaces
However, it should also be borne in mind that your wireless network requires a defense mechanism to ensure the safety of connected devices and information.
Storage Area Network (SAN)
A Storage Area Network (SAN) is an architecture specifically for providing access to consolidated storage as opposed to traditional SANs which normally emphasise higher speed networks and/or fault-tolerant databases.
SAN (Storage Area Network) SANs are generally used in data-centers and big organisations where bulk amount of data need to be stored and accessed efficiently.
Organizations can centralize storage in a single location (or multiple, if needed), rather than storing all information on each computer (like old device-to-device networks connected by a low-level network).
SANs can support:
- Centralized storage
- Data backup
- High-speed data access
- Storage management
- Business continuity
They are often more sophisticated than the networks used in homes or small offices.
Campus Area Network (CAN)
Konusal Alanda Versiyon Kontrolu (CAN)’ü tanımlayan bir yazım sizin küçük mesafede batasınızdan uzunsunuz.
CANs are used in universities, colleges, research centers and large corporate campuses.
An example of this would be a campus that connects among university, library, administrative offices, laboratories and academic buildings.
A CAN would serve as a more centralized communication link over a larger area than could be achieved with typical local-area networks (LAN).
Virtual Private Network (VPN)
A Virtual Private Network, more commonly called VPN, provides a secure connection to another network over the internet.
This requires creating a secure tunnel, using VPN technology (Virtual Private Network), through which data is passed and accessed from remote locations without any security threats. For example, organizations may use VPNs to enable employees to access organizational resources securely from outside the office.
VPNs — Remote Work & Secure Access.
But a VPN should not be regarded as the physical network like LAN or WAN in nature. Essentially, it is a technology that allows for secure virtual connections to be created.
When to Choose the Right Network?
The appropriate network is determined by the needs of either the user or the company.
Consider the following factors:
Area of Coverage
A LAN or WLAN should suffice for a small home/office. Is WAN technology required for larger geographical requirements?
Number of Devices
Network design is impacted by the number of computers, smartphones, servers and other devices.
Security Requirements
You need the necessary security controls, authentication, monitoring and access management for that critical business information.
Budget
A more complex networking infrastructure may call for additional equipment, maintenance and professional expertise.
Performance
There are many types of organizations that require networks built for high throughput and resiliency because they deal with big data.
