Business IT Networks
What are business networks?
Small businesses and home offices tend to have networks in place which are similar to the one you have to access the internet at home. These are generally set up with either one or two local area networks (LANs), each of which is controlled by its own network router.
As businesses become larger, so do the number of LANs to support their connectivity needs. These can be accessed both through wired connections using Ethernet cabling for higher speed and better performance and through wireless connections using Wi-Fi for more convenience.
When businesses become larger still and are based in more than one location, internal connectivity can be set up between offices. This is referred to as a campus network when the buildings are nearby one another, and wide area networks (WANs) when they are spread across different cities or countries.
Business networks accessing the internet
Companies generally allow their employees access to the internet using their business network. Unfortunately, this can leave businesses exposed to malicious software and untrusted websites. To combat this, many businesses use internet content filtering software to block access to selected websites and domains which may violate the company’s acceptable use policy.
Employees may also be given remote access to the business network so they can work from home or other locations. This can be done using a virtual private network (VPN) which set up by the company and then configured on employees’ computers and is a convenient and secure way to offer more flexibility in the workplace.
