THIS WEEK’S FOCUS: Computer Maintenance

FIVE WAYS TO SPEED UP YOUR PC

You read the title, so let’s get right to it:

  • Delete unnecessary files—Your computer runs faster when you have some free hard disk space. The easiest way to free up more space is to delete unnecessary files, via Windows XP’s Disk Cleanup tool.

  • Delete unused programs—Another great way to free up valuable hard disk space. Use the Add/Remove Programs utility from the Windows Control Panel.

  • Defragment your hard disk—Fragmented disks run slower, so you should run the Windows Disk Defragmenter utility at least once a month.

  • Fix hard disk errors—Keep your hard disk spinning smoothly by occasionally running the ScanDisk utility. This will find and fix any errors on the hard disk.

  • Reboot—Even though Windows XP appears to run smoothly for extended periods, you can still get memory leaks and unclosed utilities that will slow things down over time. Clear up all the loose ends by rebooting your machine occasionally, which starts everything fresh.

ON THIS DAY: THEORY OF RELATIVITY PUBLISHED (1916)

In 1916, Einstein’s Theory of General Relativity was published as an academic paper in the Annalen der Physik. Einstein’s theory showed that Newton’s Law of Gravitation was only approximately correct, breaking down in the presence of very strong gravitational fields.

FACT OF THE WEEK

Jupiter Research (http://www.jupiterresearch.com) says that 32 million U.S. households—about half of all online households—had broadband access in 2004. This number is expected to grow to 78% (88 million) by the end of 2010.
