Different Types of Network

Choosing a career in information technology (IT) or a relevant field requires knowledge of computer networks. Insights about computer networks and their types can help you gain knowledge and build a dream career in this field. This knowledge also allows you to maintain and control them in the workplace.

Are you curious to know more about computer networks and their types? Read this blog to learn the different types of networks and the objectives of deploying these networks.

Understanding Computer Networks

A computer network is a computer system that helps devices connect. With a network, people can connect to the web, share or receive files, and communicate with others, depending on the type. Devices can connect with each other using wired or wireless networks.

Importance of Understanding Computer Networks and Types

Understanding the different types of networks is crucial to building a career in IT and software. Each network type controls a different level of user traffic. They differ from each other in size, location, and accessibility. This difference makes it necessary for the network type to align with the particular needs of a user or a business.

What are the Different Network Types?

Gaining insights on various network types is essential to know their functions and their importance in user needs. Below are the ten different types of networks that are useful in daily human life:

• Local Area Network

The Local Area Network (LAN) is the most common network type. A LAN helps users connect in a common area and over a short distance. Users get access to the same resources after connecting to a LAN. You can connect your mobile to the internet and connect smart devices with the same network.

• Personal Area Network

A personal area network (PAN) depends on wireless signals to connect devices in a small area up to 30 feet. PANs are essential for connecting Wi-Fi, Bluetooth, or other technologies to wirelessly connect devices like mobile phones, laptops, and desktops. A PAN also allows a business team to collaborate and ensure seamless file sharing.

• Metropolitan Area Network

A Metropolitan Area Network (MAN) is a type of network that provides network connectivity in an entire region. Wired networks, like data cables, cover the entire town or a portion of a city. Because wired connections are installed in MANS, the speed of data transmission is relatively high.

• Wide Area Network

A wide area network (WAN) is a broad network that is not restricted within a geographical region. Organisations or MNCs may use WANs to share a common network with broader connectivity. Because of the large distance, the speed of WAN data transfer is comparatively lower than that of MAN and LAN networks.

• Wireless Local Area Network

A wireless local area network (WLAN) is similar to a LAN since it transmits data in a smaller area. WLANs allow users to use their devices in different locations. However, they are less secure and comparatively weaker than other networks.

• Campus Area Network

A Campus area network (CAN) is smaller than a MAN but more significant than a LAN. The key objective of using a CAN is to connect the LANs covering each campus building. This network allows people on the campus to collaborate, use similar resources, and share data.

• Storage Area Network

A storage area network (SAN) is a special category of network used for warehousing data. Since it possesses specific functions, SANs are not considered the main network for an organisation. They allow companies to keep the storage infrastructure separate. For instance, a business team stores customer data in a separate network to maintain the high speed of its primary network.

• Virtual Private Network

A virtual private network (VPN) strengthens the connection between a user’s device and a network server. This type of network is useful for remote employees who connect to a business network from public internet connections. It also enhances security during the transfer of digital data between companies.

• Enterprise Private Network

Businesses build and operate enterprise private networks (EPNs) only for their internal use. Using an EPN, enterprises communicate with their workers and transfer data. However, anyone outside the company cannot access this private network. These networks can be customised to fit a business’s specific functions.

• System-Area Network

A system-area network provides connectivity in clusters. This type of network connects various devices and operates as a single system of networks. System-area networks are used for communication between computers, customising them to increase speed and focus on particular functions.

Objectives of Deploying a Computer Network

Now that you have understood the different types of networks, you must also know what are the objectives of using them:

• Cost Reduction: Computer networks allow users to save time and increase effectiveness. They allow users to access information in less time, which saves operational time and costs.
• Minimising Errors: Networks reduce errors by keeping all involved parties getting data from a single source, even if they are seeing it from varied regions.
• Resource Sharing: Computer networks also allow data to be accessible to each user irrespective of location. This helps the users with interdepartmental data processing.
• Performance management: When a company experiences growth, it can feel the data-related workload. Computer networks boost tier performance by offering the necessary processors.

Final Words

Computer networks ensure productivity, innovation, and security, and reduce costs. Understanding different types of networks is important, as each has distinct features for providing connectivity.
