One of the advantages of LCDs over cathode ray tube (CRT) monitors is lack of flicker. CRTs produced eye-fatiguing flicker if the refresh rate was set below 70 hertz (Hz).
The refresh rate that many LCD monitors use, however, are set to run at 60Hz. This is fine for flicker-free images on LCDs.
These flat-panel monitors use different technology for their display of images, so the old rules for flicker-free monitor operation no longer apply.
Anti-spyware protection
DO you need an anti-spyware program in addition to antivirus? Probably so.
While antivirus software makers have added anti-spyware protection to their packages, antivirus is still their forte, and the anti-spyware packages on the market have been protecting against spyware longer.
To get rid of spyware, download the free Windows Defender if you’re a Windows user. Also consider Ad-Aware.
External hard drive back-up
THE cheapest way to back up the data on your hard drive today is with another hard drive.
Either an external hard drive, which connects to your computer using a USB or FireWire port or an internal model will suffice.
Remember when budgeting for data storage to think about buying twice the amount you’ll need – half for your files and programs, and the other half for the backup of those files and programs.
Virtual computers cut cost
Microsoft has quietly unveiled Windows Server 2008. Intended primarily for businesses, Windows Server 2008 offers virtualisation for the first time in a Microsoft operating system.
Virtualisation, dubbed Hyper-V by Microsoft, allows one computer to act as though it is many. Each virtual computer is protected from the others on a machine.
Virtualisation helps companies save cost by reducing the number of computers they might otherwise devote to several tasks. – dpa
