Wired networks: characteristics, types, advantages and disadvantages

The wired networks They are described as an arrangement that involves cabling to establish links to the Internet, to computers, and to other devices on the network. Data is transferred from one device to another using Ethernet cables.

The term “wired” is used to distinguish between connections that include wired and wireless. Unlike wireless devices that communicate over the air, a wired network uses physical cables to carry data between different devices and computer systems.

For as long as there has been dial-up, the way employees access data and applications has changed dramatically with the advent of new technology and faster Internet connections. In fact, the latest trends aim to cut the cables completely in favor of greater mobility and flexibility.

Although wireless mobility is a great advantage of access to information, a large number of entities give greater preference to the security of wired networks.



Today’s wired networks generally involve having Ethernet connections, which use a standardized network protocol and cables similar to landline telephone cables.

An Ethernet system uses a copper twisted pair cable or a coaxial cable-based transport system. Recent Ethernet wired networks achieve speeds of up to five gigabits per second.

The Ethernet cable used is unshielded twisted pair. It is used to connect different devices. However, it is bulky and expensive, making it less practical for use in the home.

A phone line, on the other hand, uses the telephone wiring found in most homes, and can provide fast services like DSL.

Finally, broadband systems provide cable Internet. They use the type of coaxial cable that cable television also uses.

Connect to a wired network

To make up most wired network connections, all you need to do is plug in a network cable.

If only two computers are planned to be connected, all that will be needed is a network interface card (NIC) in each computer and a cable to run between them.

If you want to connect multiple computers or other devices, you will need additional equipment: a router or switch, depending on your network setup. A cable will also be needed to connect each computer or device to the router.

Once you have all the equipment, all you need to do is set it up and configure the computers so they can communicate with each other.


twisted pair cable

It consists of two different conductor cables that are crimped with each other. Several of these pairs come bundled in a protective sleeve. It is the type of cable that is most used for transmission. The twisted pair is of two kinds:

Unshielded Twisted Pair (UTP)

This class of cable has the ability to block interference without having to rely on physical shielding to do this. It is used for telephone applications.

Shielded Twisted Pair (STP)

This variety of cable has a special jacket to prevent interference. It is used for high-speed transmissions and also in the data/voice conduits of telephone lines.

Coaxial cable

It has a plastic casing inside which there are two parallel conductors, each one with its own particular protection cover. It transfers data in two ways: baseband mode and broadband mode.

Cable television and analog television networks make extensive use of coaxial cables.

fiber optic cable

It uses the concept of light reflection through a glass or plastic core. The core is surrounded by a less dense covering of glass or plastic called the cladding. It is used for the transmission of large volumes of data.

Advantages and disadvantages

– Advantages

Greater security

The cables allow for greater security, reliability and control. Unauthorized users cannot access the network, which increases security.

Using physical connections might not seem so advanced, but it is the best option when data is valuable and sensitive.


Wired connections will always be faster and more consistent than wireless connections.

Wired networks achieve fairly high top speeds and have an easier time being able to maintain those top speeds.

less interference

Wired networks are less vulnerable to radio interference, thus resulting in fewer lost packets that would have to be retransmitted.

Because of this, a wired connection is preferred when using commercial applications where reliability is critical.

lower cost

The structure for a wired network can be quite cheap to install. Cables, switches, routers, and other devices can be considered cost-effective.

Also, the lifespan of hardware usually stands the test of time before needing an upgrade.

Higher productivity

Maintaining a wired network ensures that the network will not be bogged down with non-essential data traffic.

In addition, there is no risk that workers with their mobile phones will start browsing social networks while they are at work.

– Disadvantages

use of cables

The real drawback with wired networks is the physical cables. It is preferable to choose a wireless network if the sight of a cable causes discomfort.

On the other hand, running cables through walls is not a quick task and cables need to be managed properly to prevent their degradation.

lack of mobility

A wired network is a physical connection that works like a tether. This means that the reach of the cable is what determines how far the devices connected to the network can move.

Using a device in a different location requires additional cables and switches to be able to connect the device to the network.


Wired networks may take longer to configure because they require more components to complete the installation.


If you have a small network structure, there is no need for a server. However, as more devices are added to the network, a server is required to handle connectivity and workload.

When a wired network demands a server, its maintenance may cost more.
