- Each computer must have a network interface with an external jack to plug in the cable and
- Network settings on each computer are configured appropriately
To create dedicated cables with Ethernet, USB, serial or parallel cables, required:
Note: Phone lines and power cords cannot be used to connect two computers directly together.
Connect two cable computers through the central infrastructure
Instead of connecting cables directly between two computers, computers can be 'joined' indirectly through a central network device. This method requires two network cables, each of which is used to connect the computer to the central device. Some types of central devices that can be used for this type of network connection are:
The implementation of this method often requires additional costs for the purchase of additional cables and network infrastructure. However, you can choose this method if you want to expand your network in the future.
Most cable networks use Ethernet technology. While there are other ways that USB hubs or the use of power network and home phone networks can be used instead. However, traditional Ethernet solutions often offer higher reliability and performance.
Wireless connection of two computers
In recent years, wireless networking solutions have become more and more popular in network connections. As with cable-running solutions, there are also a number of wireless technologies that support the networking of two computers:
Wi-Fi connections can reach farther distances than other wireless connections listed below. Many new computers, especially laptops, now have Wi-Fi capability. Wi-Fi can be used with or without centralized network equipment. With a network of two computers, connecting to a Wi-Fi network will not require a centralized device (the mode used to connect is ad-hoc mode ) which is set up very simply.
Bluetooth technology supports high-speed wireless connections between two computers without the need for a centralized network device. Bluetooth is often used when connecting a computer to a handheld device such as a mobile phone. Most desktops and older computers do not have Bluetooth functionality. Bluetooth works best if both devices are placed in the same room at a close distance. You can choose a Bluetooth solution if you are interested in connecting to handheld devices and your computers lack Wi-Fi functionality.
Infrared connections existed on laptops for years before Wi-Fi and Bluetooth technology became popular. Infrared connections work only between two computers, do not require centralized equipment and are also quite fast. The connection setup process is very simple, you can choose this solution if your computers support it and you do not need to attempt to use Wi-Fi or Bluetooth connection.
If you find another type of wireless technology called HomeRF , you can ignore it because the technology has become obsolete a few years ago and is not suitable for home networking.
