A Complete Guide to Network Cards & Adaptors

If you have a laptop or desktop computer, chances are it has an ethernet port on the back. The ethernet cable plugs into this port and allows your computer to connect to the internet via a wired connection. You'll need wireless network cards & adaptors if you want to connect wirelessly. This will allow your computer to access WiFi networks without needing an ethernet cable — pop it in and start surfing!

What are network cards & adaptors?

Network cards

A network card is a hardware device that allows a computer to connect to a network. It's inserted into your computer's motherboard and then connected via cable to your router or modem. Network cards are also known as ethernet cards, NICs (Network Interface Cards), or wireless adapters for laptops.

A NIC is an expansion card that allows your computer to connect to a network. You can think of it as an adapter for the physical cables and wires that connect to your computer.

If you have a desktop computer, there's a good chance it came with at least one network card. However, using a laptop or tablet doesn't always come with built-in network cards; they use wireless adapters instead.

Network adapters

Network adapters are often used interchangeably with network cards, but they're not the same. Network adapters can be built into the motherboard or installed separately. They're often used in laptops or workstations where there isn't room for a card that plugs into a PCI slot.

What are the benefits of network cards & adaptors?

A network card, also known as an Ethernet card, is a computer component that connects your desktop or laptop to a local area network (LAN). The card allows you to connect multiple devices to the same network, which makes sharing information between computers and other devices much more accessible.

There are several advantages to using network cards & adaptors. First, it allows you to share files stored on each computer with everyone on the same network. You can also use the card to access shared printers and other peripherals.

Another benefit of using network cards & adaptors is that it enables you to set up your home or office network without buying expensive equipment such as routers or switches. A router is a device that lets all computers connected through it communicate with each other so they can share resources such as printers and Internet access; a switch allows computers to communicate directly with each other without going through an intermediary device like a router or hub (which is similar in function but less sophisticated).

Network cards & adaptors offer many benefits over other networking solutions because they are inexpensive and easy to install. They provide fast speeds for transferring data between computers and peripherals; they're compatible with most operating systems; they support wired and wireless connections; they don't require any particular software installation.

Ethernet vs. WiFi

There are two main types of network connections: Ethernet and WiFi.

Ethernet is a wired connection, meaning you must have the device (e.g., laptop or tablet) physically connected to the router via an Ethernet cable. You connect your computer or another device to the router using Ethernet by plugging one end into an available port on your modem/router, then running an additional cable from that port to wherever you want it installed.

If you don't want any cables running all over your home or office space, this option may not be ideal for you because it requires a lot of work to get everything set up.

WiFi is a wireless connection that allows users to connect their laptops or tablets directly with their networks without wires, making setup much more straightforward than an Ethernet network card.

Most modern routers will come equipped with built-in WiFi capabilities, so there's no need for additional equipment when setting up such networks. However, some older models might require different access points before getting started (these could range anywhere from $100-$400 depending on how many devices need connecting).

How do you set up network cards & adaptors?

After you have the network cards & adaptors, you must connect them to the computer and install them. To do so:

  • Install the network adapter by connecting its cable to your computer. Install any software with the card into your operating system if needed.
  • Connect a cable from one side of each port on your switch or hub to a port on your router or modem, then connect another cable from one side of each port on an additional switch or hub to link two or more computers together in a local area network (LAN).
  • Plug one end of an Ethernet cable into each router's port; this allows devices such as laptops, printers, and game consoles that use wireless connections through their adapters but need access over wired networks.

What is a wireless USB adapter?

A wireless USB adapter is a small device that plugs into a USB port on your computer or laptop. It allows you to connect to a wireless network without an internal card. The adapter is similar to a network card but is wireless and does not require any extra hardware or software for installation.

This makes it ideal for users who do not have spare PCI slots on their computers and laptops and those looking for an easy way to wirelessly connect to their home networks when they are out of their homes.


Network cards & adaptors both do the same thing. They allow your computer to connect to a wired/wireless network. The main difference is that a network adapter lets you connect wirelessly. At the same time, Ethernet requires an Ethernet cable running from your PC to another device, like an access point or router.
