This will teach you the basics of computer networking and how to share files on both Windows and Mac. Computer networking is easy to do once you understand what the different components are and how they work, and we'll walk you through everything you need to know. Check out the steps below to get started!

Steps

Part 1 of 5:Learning Computer Networking Basics

1Understand what computer networking is. Networking refers to connecting two or more computers to one another, usually for the purpose of sharing files between them. This concept also applies to network items (e.g., printers) which can be shared by any computers which are networked to the computer to which the printer is connected.

Networking usually requires that you enable settings on your computer which make it more vulnerable to outside interference. If you're going to network your computer, make sure it has a password.

Networking can also apply to wireless connections, such as the ones used to connect one computer to an Internet modem.

2Know the different components of a wireless connection. When connecting your computer to a wireless Internet connection (Wi-Fi), you'll need to know what the following terms mean:

Router — Connects to an Internet modem in order to broadcast a wireless Internet signal.

Modem — Bridges the connection between the hard-wired Internet cable and the router. Some routers and modems are built into the same unit.

SSID — The name of your wireless network.

Key — The password used to log into your wireless network.

3Learn how Ethernet works. You can use Ethernet cables to connect two computers to one another, to connect a computer directly to the modem or router, or to connect a computer to another network item such as a printer. Using Ethernet generally leads to a more consistent connection between two items, but can also be limiting due to the fact that not all computers support Ethernet.

Ethernet cables can be found in tech stores and in online locations such as Amazon.

If you're using a Mac laptop or some Microsoft notebook laptops, you most likely don't have an Ethernet port. You can solve this problem by buying a USB (Windows) or USB-C (Mac) Ethernet adapter and plugging it into your computer.

4Connect a computer to Wi-Fi. Connecting to Wi-Fi will vary slightly depending on your computer, but you'll usually click the Wi-Fi logo in your computer's taskbar or menu bar, click the name (SSID) for your preferred Wi-Fi network, enter the password for the network, and follow any on-screen instructions from there.

Always make sure you're in range of the Wi-Fi network when connecting. In most cases, this means being within around 100 feet of the router, though being closer when first connecting is best.

5Always use a password. As mentioned earlier, networking your computer places it in a vulnerable state in which others can view your files. If your computer uses a password, this isn't a problem; however, failing to use a password means that anyone on your network who has your computer's username can view your computer's files.

The same goes for your wireless network.

Part 4 of 5:Accessing Shared Files on Windows

1Make sure you're using the correct network. Both your computer and the computer to which you want to connect should be connected to the same Wi-Fi network in order for you to access their shared files.

If you're connected to the other computer via an Ethernet cable, you should be able to access the shared files.

If your router has different channels (e.g., 2.4 GHz and 5 GHz), it's okay for the computers to use different channels as long as they're using the same network name (SSID).

2Open File Explorer . Click the folder-shaped File Explorer app icon in the taskbar to do so.

You can also just press ⊞ Win+E, or type file explorer into Start and then click File Explorer when it appears.

3Click Network. It's on the left side of the File Explorer window, though you may need to place your cursor on the left-hand sidebar here and scroll down to view it. This will bring up a list of all your currently connected network items.

4Double-click the computer's name. You should see it in the main window. Doing so will open a login form.

If you don't see the computer's name, right-click a blank spot on the page and click Refresh. If the computer still doesn't appear, make sure file sharing is turned on for the computer.

5Enter the other computer's login information. In the pop-up window which appears, type in the other computer's username and password.

6Click OK. It's at the bottom of the window.

7Browse the other computer's shared folders. As long as you enter the correct username and password for the other computer, this will allow you to open any folders you see in the Network window.

You may even be able to add files and folders or edit the existing ones if the other computer allows it.
