What you should know before setting up a LAN
A LAN can enhance your small business’s capabilities and benefits. It’s a technology you’re probably already familiar with but don’t fully comprehend. We’re discussing a local area network (or LAN).
Do you have a computer and a laptop connected to a printer at home? Congrats! You now have a local area network. Simply put, a LAN is a collection of computers and devices in the same location that are linked to one another.
A Network’s Components
A network is made up of two or more computers, an Internet connection, and basic networking equipment like a router and peripherals (i.e., a keyboard and mouse).
Internet Access
The Internet is the lifeblood of the majority of businesses. For a monthly fee, a company can obtain Internet service from an Internet Service Provider (ISP). The ISP can assist the company in determining which speed options are best for it. Bandwidth is typically determined by the number of users and devices on the network, as well as the tasks for which employees will use the Internet. After installing Internet service at the business location, the user can connect to the Internet via a computer or computer network.
Router
A router connects multiple computers and assigns unique IP addresses to each device. Many ISPs include a basic router in their installation. Business-grade routers include advanced security features such as a firewall, anti-spam, anti-virus, and wireless options. These provide more customization options. This router also allows for the creation of a virtual private network (VPN), which allows employees to connect to the network while away from the office. If the ISP does not supply a router, there are several designed for small businesses or home offices that include special software that guides the user through the setup process, further simplifying the process of establishing a network.
A typical router has multiple ports for connecting multiple computers or other devices, allowing the user to share the Internet connection among those devices.
Cabling
To connect your router to the computer or to connect multiple computers, you’ll need an Ethernet or fibre optic cable. Which option is best for you is determined by your budget, bandwidth requirements, and security requirements. Fiber is more expensive, but it generally provides faster speeds, and because it transmits data via light rather than electrical signals (as Ethernet does), it is less susceptible to interference or being intercepted. Ethernet is becoming faster, with Category 6 (CAT6) cables capable of supporting transfer rates of up to 10Gbps, but it has distance limitations.
After a company has installed the necessary equipment and network components, a user can manage his or her network using a computer’s operating system (OS), such as Microsoft Windows, Linux, or Mac OS. Most operating systems include functionality for managing a small network, such as the ability to add users, files, and folders, as well as enable printer-sharing options. If the laptop or desktop is relatively new, completing the network setup should be relatively simple.
