Network engineers are in high demand, with over 650% job growth in less than a decade. There are plenty of reasons these are becoming crucial to businesses of all sizes.

They can help your scale more efficiently and end up saving you money. Wouldn’t that be nice?

However, that’s not all network engineers can offer. Read on to find out what network engineers actually do and how they could benefit your business.  

What Is a Network Engineer?

A network engineer is a highly skilled professional. They oversee the design, implementation, oversight, and maintenance of an organization’s computer network. 

The network supports in-house data, voice and video, and wireless transmission. Network engineers are also known as network architects.

The main goal of a network engineer is to maintain a secure environment. They also aim to provide an infrastructure that will offer the best performance to users.

Some organizations opt to have a wide array of network engineers working remotely. Even from several different countries. Doing so ensures their global connectivity rarely misfires.

What Do Network Engineers Work With?

Network engineers work with networks (who’d have thought?).

Yet, there are several different types of networks that they build and repair, let’s take a look at them.

Wired Computer Networks

A computer network connects several computers. They do so via nodes to enable secure data, voice, and video transmission from one computer to another. There are four types of computer networks:

Local Area Networks (LAN) is a group of computers connected in a small geographic location. LANs could be over one building or several such as a school or prison.

Personal Area Network (PAN). A PAN connects an individual’s personal devices and covers a small radius of about 10 meters. It can either be a wired or wireless connection.

Metropolitan Area Network (MAN) – covers a large geographical area and interconnects several LANs. (Usually within cities).

Wide Area Network (WAN). It spans over a larger geographical area than MAN extending to continents. The internet is an example of a WAN.

Further, networks connect in different layouts referred to as network topologies. Some of the common topologies are ring, bus, mesh, star, and line topologies.

An ideal computer network can use any of these topologies or a combination of several.

Wireless Networks

A wireless network with communication via a wireless connection between network nodes.

The following are the different types of wireless networks:

  • Wireless Personal Area Networks (WPAN)
  • Wireless Local Area Network (WLAN) 
  • Wireless Metropolitan Area Network (WLAN)
  • Wireless Wide Area Network (WLAN)
  • Cellular Network (also known as a mobile network)
  • Global Area Network – A network that allows a mobile to traverse several wireless LANs
  • Space Area Network – An example is NASA’s Space Network (This network provides communication between space crafts) – We doubt you’ll need to use this one!

What are the Roles of a Network Engineer?

Today, most businesses connect through at least one type of network. Whether it’s a local area network or a wide area network, they’re all connected. A network engineer comes in handy to ensure these networks are up and running.

There are several roles that a network engineer handles in a network. If your business needs help with any of these issues, using a network engineer is the way to solve them.
