16. Laptop PCs: basic troubleshooting and repair

Individuals who seek to get work done away from an external power source cite usable battery life as one of the key factors involved in how much work they can get done while on the go. Yet many of those same individuals don't know how much latitude they have in controlling power consumption while operating on battery power, nor do they always take the steps necessary to maximize battery lifetime. Over the long term, proper storage of your battery when not in active use can also extend its lifetime significantly as well.

18. MbPS Megabits (mb) per second. A bit is either a 0 or 1 (a digit) and a byte is a string of 8 bits. 8 mbps (megabits per second) equals 1 MB/sec (megabytes per second). Therefore 54 mbps is equal to a max of 6.75 MB/second.

19. Move Over External Hard Drives, NAS is Here! Network Attached Storage isn't new, but it's become affordable, and it has many advantages over the external hard drive. The NAS (Network Attached Storage) device is a lot like an external hard drive and connect similar to how network file servers connect. NAS devices are similar. They typically have a small, firmware-embedded Linux kernal, a web-hosted management interface, and support some number of hard drives.

20. RAID

RAID is the acronym for a Redundant Array of Independent Drives. RAID specifies several "levels," 0, 1, etc. Different levels provide different options. One level allows you to combine multiple smaller drives into one, huge volume. Another level offers tremendous performance boosts by "striping" data across multiple drives such that reads and writes are split across the drives. If one drive fails, the other takes over until the bad drive is replaced. Once replaced, the RAID subsystem automatically restores the mirror.

24. The Wonder of Network Print Servers

Network print servers are an inexpensive and great solution to a common home or office network.  Sure you can "share" printers attached to particular machines, but that creates a dependency on that machine being up and running.

With a network print server, that dependency disappears. People on the network can print without a particular machine being on and available.

They solve one other important problem, too.

27. Weak Wireless Signal

If you have a USB wireless device such as a wireless NIC, mouse controller, etc. that has a weak signal because of location, try adding a USB extension cable and placing the device in a more open location.

USB cables from stores such as Radio Shack, Best Buy, etc. are over priced 5 or 6 times what you can get on the internet.

For wireless network cards, you can also buy a range-extending antenna for the computer's WiFi card or router, or a wireless range extender.

29. Wireless Router & Security: A Step-By-Step Guide

Setting up a wireless router is easy. Essentially you turn your cable or DSL modem off and your wireless router on. Then, you connect the router to the modem with a cable, and turn the modem back on. You are more or less done. The wireless network wizard on your computer will pick up the router and, if your ISP does not have any special requirements, away-you-go, you are on the Internet.
