What Are Computer Networks?

A group of linked devices that interact and share resources, including computers, printers, servers, routers, and switches, is referred to as a computer network. Networks are an essential component of contemporary technological infrastructure because they provide smooth communication, data transfer, and resource sharing amongst various devices.

Protocols and Communication in Computer Networks

Protocols, which are a collection of guidelines controlling data transfer, are used by computer networks. Transmission Control Protocol/Internet Protocol (TCP/IP), the most widely used communication protocol, enables data transfer between several devices, independent of their location.

Computer Network Types by Scale and Range

Based on their size, geographic reach, and coverage area, computer networks may be widely classified. The main categories of computer networks are listed below, each of which is appropriate for a certain set of requirements and uses.

1. LAN, or Local Area Network

A local area network, or LAN, is a collection of computers and other devices that are restricted to a certain area, such a house, workplace, or building. LANs are often used to link servers, printers, PCs, and other devices in a constrained space. They make it possible for devices to connect effectively by sharing resources like files, apps, and internet access.

• LAN Characteristics: Often covering a limited region, such as a school or a single building.
• Data Transfer Speed: Fast data transport, often between 100 Mbps and 10 Gbps.
• Connection Methods: Both cable (Ethernet) and wireless (Wi-Fi) connections are used to connect devices.
• Cost: Comparatively inexpensive setup and upkeep costs.
• Administration: Centralized administration, which often uses a server to regulate resources and access.

Best Uses for LANs

• Corporations, offices, and educational institutions use LANs to share printers and data.
• LANs are essential for multiplayer gaming in gaming communities.
• LANs make it easier for linked devices to communicate and transfer files quickly.

2. WAN, or Wide Area Network

Connecting many local area networks (LANs), sometimes spanning towns, nations, or even continents, a wide area network (WAN) covers a much greater geographic region. The biggest example of a WAN is the internet. WANs use satellite connections or leased telecom lines to interconnect geographically separated networks.

• WAN Characteristics: Large geographic regions are covered by WANs, which often link networks spanning towns, nations, or even continents.
• Speed: Slower data transmission rates, usually between 1 Mbps to 100 Gbps, in comparison to LANs.
• Management: WANs are usually administered by service providers and need expensive infrastructure.

Applications of WANs

• Big businesses with many office sites dispersed over various areas make use of WANs.
• Worldwide communication, online services, and resource sharing are made possible via the internet, which functions as a worldwide wide area network.
• WANs are essential for connecting data centers and cloud services together.

3. MAN, or Metropolitan Area Network

Usually found in a city or a large campus, a metropolitan area network (MAN) is intended to span a wider region than a local area network (LAN) but a smaller area than a wide area network (WAN). For businesses with many branches or sites in a metropolitan region, MANs are perfect.

• MAN Characteristics: Covering a medium-sized geographic region, such as a city or a sizable university.
• Speed: Usually works between 10 Mbps to 1 Gbps, which is faster than WANs.
• Ownership: May be run by a service provider or privately owned.
• Technology: Uses high-speed data transfer technology, such as fiber optics or leased lines.

Applications of MANs

• MANs are used by government agencies, corporations, and universities in urban areas to link many branches or offices.
• In a city, MANs are used to link cloud services or data centers.
• MANs are used by cable companies to disperse television signals.

4. PAN, or Personal Area Network

For personal devices like wearables, computers, tablets, and smartphones, a Personal Area Network (PAN) is a tiny network. PANs are often used to link Bluetooth-enabled devices and have a relatively narrow operating range, usually a few meters.

• PAN Characteristics: Covering a fairly narrow region, often within a 10-meter range.
• Connection Methods: Mostly used to link personal gadgets using wireless technologies such as infrared, Bluetooth, and Zigbee.
• Cost: An inexpensive, low-power network that is perfect for individual usage.

Applications for PAN

• Used to link a smartphone to a wristwatch, Bluetooth speakers, or wireless headphones.
• PANs are used between nearby personal devices to share files and print.
• Permits communication between Internet of Things (IoT) devices in a home automation system.

5. SAN, or Storage Area Network

A specialized network called a Storage Area Network (SAN) is used to provide users fast access to storage devices like tape libraries and hard drives. To guarantee that massive volumes of data can be effectively accessed and moved between servers and storage devices, SANs are often used in data centers.

• SAN Characteristics: Low latency access to storage devices and high-speed data transfer optimization.
• Communication Technologies: Makes use of communication technologies such as FCoE (Fibre Channel over Ethernet), iSCSI, and FC (Fibre Channel).
• Flexibility: Multiple servers may be connected to centralized storage via SANs, providing flexibility and scalability.

Applications of SAN

• Often used to handle and store vast volumes of data in business settings.
• Used for disaster recovery and data backup solutions.
• In settings that need high-performance applications, such as scientific computing and video editing, SANs are crucial.

6. VPN, or Virtual Private Network

In order to provide encrypted communication between distant users and corporate networks, a Virtual Private Network (VPN) is a private, secure network that spans a public network, such the internet. By hiding the user’s IP address and encrypting their internet activity, VPNs provide a safe connection.

• VPN Features: The ability to create an encrypted tunnel for data transfer, which offers privacy and security.
• Remote Access: May be used to safely link distant employees to the internal network of their business.
• Protocols: VPNs may be set up using a variety of protocols, including IPsec, L2TP, and OpenVPN.

Uses of VPNs

• Businesses often use VPNs to enable staff members to safely access company resources from distant locations.
• When using the internet, people utilize virtual private networks (VPNs) to preserve their privacy and get around regional limitations.
• VPNs are also necessary for military and government applications that need secure communication.
