Introduction to Networking Essentials: Types of Computer Network Devices
Whether you are just starting out setting up a computer network or you’re already familiar with the basics, it’s important to understand the different types of devices used to create and maintain computer networks. Networking devices are the foundation of any computer network and play an important role in maintaining the network.
In this article, we will explain the different types of computer network devices, their uses and how they interact with other network components. After reading this article, you should have a better understanding of how the components of a network work together.
Types of Computer Network Devices
The devices used to create and maintain a computer network can be divided into two main categories: hardware devices and software devices. The most common types of computer network devices are routers, switches, bridges, modems, hubs, firewalls, and wireless access points (WAPs).
Hardware Devices
Routers
Routers are the most essential hardware device in any computer network. A router connects multiple networks to create an internet connection and allows devices on the same network to communicate with each other. Routers are also used to control what type of traffic is allowed on a network and are responsible for forwarding data packets between computers on the same network.
Switches
Switches are used to connect multiple devices on the same network. They can be used to connect computers or other networking devices such as routers. Switches are responsible for forwarding data packets between devices on the same network.
Bridges
Bridges are used to connect two separate networks together. They are used to extend the range of a network and allow devices on one network to communicate with devices on another network.
Modems
Modems are used to connect a computer to the internet. They convert data signals into a form that can be transmitted over a telephone or cable line. Modems can also be used to connect two computers together and create a local network.
Hubs
Hubs are used to connect multiple devices on the same network. They are similar to switches but are less sophisticated and provide less features.
Firewalls
Firewalls are used to protect a network from malicious attacks. They can be either hardware or software and are responsible for monitoring and blocking any suspicious traffic.
Wireless Access Points (WAPs)
Wireless access points (WAPs) are used to create wireless networks. They allow devices to connect to the network without the need for cables.
Software Devices
Software devices are used to help manage and secure a network. The most common types of software devices are protocols, security software, and monitoring software.
Protocols
Protocols refer to the rules that are used to define how computers communicate with each other. The most commonly used protocols are TCP/IP (Transmission Control Protocol/Internet Protocol) and UDP (User Datagram Protocol). These protocols define how data is sent between computers on a network.
Security Software
Security software is used to protect a network from malicious attacks. It is responsible for monitoring and blocking any suspicious traffic and can be used to prevent data from being accessed without authorization.
Monitoring Software
Monitoring software is used to monitor the performance of a network. It is responsible for collecting data such as the amount of traffic flowing through the network and the speed of the connection. This data can then be used to improve the performance of the network.
Conclusion
These are the most common types of computer network devices used to create and maintain a computer network. Each device has its own specific purpose and they all work together to create a functional network. By understanding how these devices work together, you can set up and maintain a secure and efficient network.
