Security Network Planning and Computer Disaster Recovery
Whether from a virus, hacking or simply a fire or flood or other act of nature- there may come a time when you will experience a catastrophic loss of computer data. We will will help you be properly prepared to recover and get back to business as quickly as possible.
Network security solution and Network Disaster Recovery is sometimes overlooked for software and database systems – until it is too late. Have you ever thought how your business would function if the computer systems and software vanished – it happens to someone every day. The Ever Growing Challenges of Data Storage is an article about the issues with storing, maintaining, backing up and recovering data on today’s massive storage media.

The Network Time Protocol – Used in Computer Networks
By description, this is a protocol designed for transfer of time around a computer network. It works through a hierarchy composed of several strata starting with Stratum 0 which provides the external source of time. Stratum 1 gets the accurate time from a hardware clock which can be got through GPS signals as they are the safest and most reliable. This is because of the many satellites that orbit the earth at any one time. The references are not limited to these as radio signals and broadcasts also provide a safe and relatively reliable source of time. The broadcasts vary with locations and are not as centralized as the GPS signals but they all provide related times, if not equal. Some common ones include MSF from the UK, JJY from Japan and WWVB from the USA.
Reliability being the main issue means that there is need for backup reference clocks in the unlikely event of a signal outage.
