However, laptops can get rather expensive so you should take care to choose a laptop withrepparttar 147754 right amount of features, but not so many that they needlessly inflaterepparttar 147755 price.

Here are 9 basic features that you should consider before you purchase your next laptop:

1. Weight and Size: When it comes to weight and size, you should consider thatrepparttar 147756 bigger a laptop is,repparttar 147757 heavier it is. A small enough size should be chosen, but not so small that it's uncomfortable. The smallerrepparttar 147758 laptop,repparttar 147759 more awkward it will be to type on that tiny keyboard.

2. Display: The display, or screen is directly tied in torepparttar 147760 size ofrepparttar 147761 laptop. You should chooserepparttar 147762 biggest display possible. Also, a decision has to be made between Active, and Passive Matrix.

Active Matrix is more expensive, but is recommended since pictures come out sharper and moving images play out smoother. Passive Matrix is cheaper, butrepparttar 147763 picture quality is not as good.

3. Batteries: There are 3 main types of Batteries. They are Li, NiMH, NiCad. What those letters stand for is not important. All you need to know is to always choose Li since they are higher quality, and provide a longer life. However, they are slightly more expensive. If one is strapped for money, then NiMH is acceptable. They're slightly cheaper, but must be recharged every hour or so. Under no circumstances should NiCad be chosen. They're extremely low quality, and have no staying power.

4. Hard-Drive: Most laptops start with at least 4.3 gigabytes, or GB, of hard drive space. However, you can get more hard-drive space if you think you’ll need it.

5. CD-DVD Drive: To be honest, a laptop doesn’t really need either one. But at least one should be added since most software comes in CD form nowadays. If you choose a DVD-ROM drive, then a CD-ROM drive won't be needed since a DVD-ROM drive can read CD-ROMs.

Wireless Network Security

Written by Lawrence Andrews

Working from home has its advantages, including no commute, a more flexible work schedule and fresh coffee and home-cooked meals whenever you want.

But working from home while using a wireless local area network (WLAN) may lead to theft of sensitive information and hacker or virus infiltration unless proper measures are taken. As WLANs send information over radio waves, someone with a receiver in your area could be picking uprepparttar transmission, thus gaining access to your computer.

They could load viruses on to your laptop which could be transferred torepparttar 147700 company's network when you go back to work.

Up to 75 per cent of WLAN users do not have standard security features installed, while 20 per cent are left completely open as default configurations are not secured, but made forrepparttar 147701 users to have their network up and running ASAP.

It is recommended that wireless router/access point setup be always done though a wired client.

Change default administrative password on wireless router/access point to a secured password.

Enable at least 128-bit WEP encryption on both card and access point. Change your WEP keys periodically. If equipment does not support at least 128-bit WEP encryption, consider replacing it.

Although there are security issues with WEP, it represents minimum level of security, and it should be enabled.

Changerepparttar 147702 default SSID on your router/access point to a hard to guess name. Setup your computer device to connect to this SSID by default.

Setup router/access point not to broadcastrepparttar 147703 SSID. The same SSID needs to be setup onrepparttar 147704 client side manually. This feature may not be available on all equipment.
