Network Installation Equipment & Devices: Full Guide (2024)

wireless internet installation

Network installation devices comprise a variety of tools and devices essential for setting up and maintaining these networks.

Each of these devices has different functions within the network that complement each other for maximum network efficacy and efficiency.

Understanding the role of these devices will give you a better grasp of how a network functions and how important comprehensive installation and configuration practices are.

6 Essential Networking Tools, Equipment & Devices

1. Hub

A hub is the simplest device on a network but is also very central to its operation. A hub links multiple devices by funneling data packets and signals to all connected devices.

A hub can transmit digital and analog data, but it must be properly configured. It also amplifies signals that deteriorate after traveling through long cable runs in a function known as repeating.

A hub does not interfere with, filter, or address data packets or signals it transmits. That’s the job of the network switch.

2. Switch

A network switch connects devices within a network and forwards data packets between them. Its job is to increase network efficiency by using routing information to read the hardware address of an incoming packet or signal and send it to the correct device.

The physical form of the network switch is generally also “multiport,” which allows multiple devices to be linked onto the network.

A switch is a more intelligent tool than a hub in directing traffic. However, it is less intelligent than a router because it has limited configuration options. Unlike a network router, which can accept and interpret packets outside the network, switches concern themselves solely with intra-network packets.

3. Router

A router determines a data packet’s best route through the network to reach its destination. The router’s job is maintaining a list of known network addresses and having protocols to direct data packets when the address is unknown.

The router stores information about the network in a data set known as a routing table, which grows dynamically as the network exchanges information.

Here’s how it works: when the router receives a packet, it analyzes it to determine its data type, source address, and destination address. This information is logged, and new addresses are added to the routing table, which helps the router learn which routes on the network are most reliable for packets to travel through.

Network topology plays a role in how routers direct data, as the routes available to a packet depend on the network’s physical and digital layout. Routers can break large packets of data down into smaller packets if the network framework requires it. They can also forward data from one network to another.

Routers are separate from firewalls but just as important to overall network security. They can be configured only to allow traffic that system administrators approve. While they can forward data from one network to another and split Internet access across multiple devices, routers can only access the Internet if connected to a network modem.

4. Modem

“Modem” is an abbreviation for “modulators-demodulator.” A modem allows your computer or network to send and receive data over the Internet, which is why rebooting a modem often addresses Internet connectivity problems. It acts as a gatekeeper for a network’s Internet access.

The modem receives an analog signal from an Internet Service Provider over analog network cables–phone lines (old-school DSL), Cat-type cable, or fiber optic cables–and then converts it into digital signals that computers can receive and understand.

While a modem is necessary for internet access, a router and switch convey that access to multiple devices on the network.

5. Firewall

Network firewalls are devices that act as a secure buffer between the inside and outside of the network. They use special protocols to police all incoming and outgoing network traffic, communications, and transactions and ensure that malware, viruses, worms, hackers, and other security threats remain outside.

Firewalls are not the only security measure you should employ on a network, but they are essential to overall network security.

6. Network Server

Network servers act as a shared central point for all devices on a server. Servers share, store, and maintain data and files that devices can access in real time across the network.

Network servers keep this shared data safe by storing it on a secure hard drive with regular backups. Because access is shared, they facilitate collaboration between different users. 

These servers also:

  • Host multi-user applications, such as email client or proprietary software
  • Connect computers to shared devices like scanners or printers
  • Centralize resources for easy research and utilization
  • Control access to these resources through the use of network log-in and connections

A dedicated file server provides additional memory space and network stability for businesses that use especially data-heavy applications, such as graphic design or CAD programs.

Integration Techniques 

Strategic placement based on network design principles is crucial for integrating hub, switch, router, modem, firewall, and server into a cohesive network infrastructure.

Hubs connect end devices, switches facilitate fast data transfer, routers route traffic between networks, modems provide internet connectivity, firewalls monitor and filter traffic, and servers centralize resources.


Why do we need network equipment and cable for network installation? 

Network equipment, such as routers and switches, along with fiber optic cables, is essential for establishing connections between devices in a network. They serve as connectors that make installation possible.

They enable data transmission and facilitate communication between computers, servers, and other network devices, forming the backbone of modern networking infrastructure.

Can I install network equipment at home?

While it’s possible to attempt network installation at home, it’s highly recommended that you seek expert assistance. For a network installation, you will need more than a kit or cable stripper for crimping and cutting. Setting up a network involves complex configurations and troubleshooting, which requires sort of specialized knowledge and skills.

Hiring a professional installer ensures proper network installation, reduces the risk of errors, and ensures optimal network performance and reliability. The Network Installers is a one-stop shop for network installation. Contact us to help you with network installation, repairs, and maintenance.
