Five factors to focus on key differences and select the needs of people who use computers to do the most basic.

1. Price

Due to the rising cost of components and assembling a small laptop is more expensive than a desktop model with the same specifications. If it is necessary only for simple tasks like word processing and surfing the Internet, a laptop might be the right choice. But for games, or a project such as video editing or desktop publishing, which requires more memory, a desktop model, the expansion takes place.

2. Space

It may seem contradictory, but while desktop computers are becoming smaller, portable computers are in the other direction to go, because the greatest number of functions, they are invited to perform.

But a laptop is better protected from the road as a desktop, this is the obvious choice when space is very limited.
The question is whether the space, the computer will never occupy a dwelling to be sacrificed.

4. Ergonomics

the existing zone in which a laptop can be used comfortably, if someone wants to spend a long period of use, it will be? This may be an important factor when choosing between a laptop and desktop models. A serious case of the hand, wrist, back, neck or eye strain is to pay too high a price for portability and style.

5. Upgrade and / or repair costs

Laptops are less robust and harder to upgrade their desktop equivalents, although their costs down, it would not be a decisive consideration. Even more important is that the damage to a laptop keyboard or screen, for example, is much more serious than on a desktop, because the essential parts of work and travel have much less protection.

Threats to computers and networks have a problem, since computers were introduced to the general public. Today, any computer or network is connected to the Internet is at risk for different types of attacks. CERT (Computer Emergency Response Team at Carnegie Mellon funded) warns that:

“Intruders form groups and develop scripts, they share with each other as viciously system vulnerabilities. Intruders dedicate time to develop programs, the vulnerabilities exploited, and exchange information. They have their own publications, and they regularly hold conferences that deal specifically with the tools and techniques to defeat security measures in networked computer systems.

Computer Brief

There are four basic components for the system we’re sitting like a PC (personal computer) that you have on your desk at work or at home.

The first is called the BIOS. BIOS stands for Basic Input Output System. It performs all the tasks to run at boot time and allows the Windows operating system to boot. Access to the BIOS can disable an attacker can complete the computer and make it unusable.
