Laptop - what does it mean? (from Wiki)
A laptop, often called a notebook, is a portable personal computer with a clamshell form factor, suitable for mobile use.1 Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, in modern usage there is often no longer any difference.2 Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia.
A laptop combines the components and inputs of a desktop computer, including the display, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. Most modern-day laptops also have integrated webcams and built-in microphones. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter. Laptops are diverse devices and specialised kinds, such as rugged notebook or convertible computers, have been optimized for specific uses. The hardware specifications significantly vary between different types, makes, and models.
Portable computers, which later developed into modern laptops, were originally considered to be a small niche market, mostly for specialized field applications, such as in the military, for accountancy, or for sales representatives. As portable computers became closer to the modern laptop, they became widely used for a variety of purposes.3
The popularity of laptops is understandable due to their functionality and mobility. Because laptops are smaller than standard computers, iIt is something much more susceptible to damage - if you pour a cup of coffee, the risk of damage to the entire laptop is enormous. If you pour a cup of coffee on a desktop computer keyboard, you have to replace a keyboard - no need extra help. Laptop can accidentally drop it on the floor, it can be thrown off the desk by a cat, or child. Desktops due to their size are less susceptible to mechanical damage. A very important feature of laptops is their portability, which means that it should be fairly light. Behind this, however, it does not go design - lightweight plastic casing is not sufficiently robust. Servicing these devices is much more expensive and not count on the manufacturer's warranty - it does not cover mechanical damage.
Computer - necessary?
At present it is difficult to imagine life without a computer. It is necessary to work - in every office, in every bank, in every school and institution.

IT professionals is one of the richest group and possibly it won't change in the future. We are not able to imagine life without the Internet, we have to unlimited access to the virtual world. Remember that the smartphone and tablet devices are type of computers too - they have their own processors, graphics chips, etc. We are completely addicted from technology - that's true.
