Computer networks are groups of interconnected computers that can communicate and exchange data with each other. They are an essential component of modern computing, enabling the sharing of resources, communication, and collaboration between different devices and users. Although most home networks have migrated to primarily wireless networking, those looking for high performance and high availability have started looking back at hard-wired networks using ethernet.
There are several different types of computer networks, each with its own characteristics and uses. Here are some common types you’ll learn about in our IT Career Program:
Local area networks (LANs):
These are small, privately owned networks that are typically used in a single location, such as an office or home.
Wide area networks (WANs):
These are larger networks that span multiple locations, often covering a large geographical area.
Personal area networks (PANs):
These are very small networks that typically cover only a few feet. Think about your phone and Bluetooth headphones, or mouse connected to a laptop.
Wireless networks:
These networks use wireless technology, such as Wi-Fi or Bluetooth, to connect devices without the need for physical cables.
Peer-to-peer networks:
In these networks, devices are directly connected to each other and can communicate and share resources without the need for a central server.
Client-server networks:
In these networks, devices are connected to a central server, which controls access to resources and manages communication between devices.
Each type of network has its own advantages and disadvantages, and the best choice for a given situation will depend on the needs and requirements of the users.
Overall, understanding the different types of computer networks and how they work is an important skill for anyone who uses or works with computers.
