A network switch is an equipment that allows two or more IT devices, such as computers, to communicate with one another. Connecting multiple IT devices together creates a communications network. Compute, print, server, file storage, Internet access, and other IT resources can be shared across the network.

SSL Certificate

An SSL certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection. Without this certificate installed, the webite's content is exposed to hacking.


SSL, or secure sockets layer, is a protocol that allows Internet users to send encrypted messages across the Internet. It is generally used when transmitting confidential information (e.g. personal data or credit card details). A web address that begins with "https" indicates that an SSL connection is in use.
