what is a network security key

Definition of Network – A network can have a fairly broad definition. In its simplest form, it always involves two or more computers that are physically connected either by cable or through a Wi-Fi connection. By being linked, these computers can share their resources, files or Internet connection without having to manually connect on each occasion.

Networks can be a lot more complex when it comes to size. For example, a family home may have a network consisting of two home computers and a Wi-Fi connection (which the family uses for various additional devices such as smart TVs, streaming boxes, smartphones, etc.). However, an office building may have an extensive network consisting of thousands of computers physically connected by Ethernet cables. Some networks may even expand to cover larger geographic areas.

There are also four main types of networks, and knowing the difference between them is essential.

Why is network needed ?

Probably, the only network you’ll deliberately see every day is a home network, aka a local area network (LAN). Not everyone needs a home network. If you only have one computer and no other devices you want to take online or share resources, there’s no need for a network.

However, most people now have their own LAN setup at home, with multiple devices connected. It’s important to know whether wired or wireless is best for your home, or a combination of the two, as well as understanding how to set up a home network.

What are the types of networks ?

The most common types of networks include local area networks (LANs) and wide area networks (WANs). The other two main types of networks are metropolitan area networks (MAN) and wireless LANs (WLAN), with wireless WAN (WWAN) also a branch of the same principle. Here is a brief description of each of the four main types of networks.

There are four types of networks :

  1. Local Area Network – The most common type of network you’ll commonly encounter, a local area network involves connecting computers over a relatively small area. That area could be your home, office or school, among other places. Devices can connect via Ethernet cable or Wi-Fi.
  2. Wide Area Network – This type of network is spread over a large geographical area such as a city, state or country. The Internet is considered the largest wide area network globally, with a wide area network allowing smaller local area networks to connect to it. Businesses may also have a wide area network linking many of their offices together.
  3. Metropolitan Area Network – Metropolitan area network is larger than LAN but smaller than WAN. Large corporations or government bodies use it to tie together various resources in a business.
  4. Wireless LAN – A wireless LAN works like a local area network, but it does so through a wireless connection such as Wi-Fi or Bluetooth, rather than using Ethernet cables.

Network Security Key

A network security key is a code or passphrase that you enter to connect your computer or mobile device to a private network. For example, if your home Wi-Fi network is secure (as it should be), you enter a network security key to join it. The purpose of Network Security Key is to prevent unauthorized access to a network and keep your Wi-Fi network secure.

How to find your network security key ?

The fastest, easiest way to find your network security key is directly through your router.

  • Log in to your home router as an administrator. Menu systems vary between router brands, but most show your network SSID and network security key on the main page.
  • If your network security key doesn’t appear on the main screen, search for Connections, Wi-Fi, or similar in the navigation menu to locate the Wi-Fi connection settings screen. You’ll probably see a network security key there.
