It's no secret that information technology can improve productivity and organization. It enables employees to use efficient, time-saving tools to accomplish their daily tasks: word-processing tools, management software, information retrieval, task automation, and so on.

Although some companies use Linux or IOS to save money, most of these computers use a Windows-type operating system. The latter is particularly vulnerable to viruses and other cyber-attacks.
