Modern PDAs can play music, games, videos, write documents, and connect to networks and databases -- nothing short of a desktop computer.

Although newer PDAs haverepparttar 133473 processing power of a computer, they still have some limitations. Inputting information is done by handwriting recognition or by a miniature keyboard. Skilled users can input 20 - 30 words per minute, less than halfrepparttar 133474 speed of a good typist on a full-size keyboard. PDAs with a color screen tend to run through battery life faster.

What to Look For

Setting up a Network -- Wired or Wireless?

To Wire or Not to Wire

Wireless networks are en vogue, but your installation wonít be successful unless you choserepparttar right type of network and set it up properly. Wired networks require that each computer be connected via a wire to a central location, called a switch or hub. This often involves installing cables through walls and ceilings and can present a challenge for anyone.

Ifrepparttar 133470 computers in your home or office are all within 500 feet of each other, a wireless network might be for you. A wireless network has no cables. It can connect computers on different floors of a building or even acrossrepparttar 133471 street. Aside fromrepparttar 133472 obvious benefit of not having wires, wireless networks are more convenient sincerepparttar 133473 setup, configuration, and reconfiguration can often be done within minutes, without extensive planning.

Wireless networks, however, are not as fast as wired networks. If you play computer games or want to view streaming video or other high-speed multimedia, a wireless network might not have enough capacity. But, if you just want to check e-mail and view web pages, a wireless network is a good choice. To install a wireless network, you need a Wireless Access Point and a wireless network card for each computer. You will need to buy a wireless network card for each desktop computer, although most newer laptops come equipped with one.

Security is not a large concern in a wired network, since someone would have to physically connect to a wired network to break in. In wireless networks, a car parked outside with a laptop could easily connect to your network if you donít have proper security in place. To prevent this from happening, encrypt your wireless network connections, or set a password to accessrepparttar 133474 network, or do both.
