The modern world is practically based on and composed of a lot of technological inventions. Technology remains basic and we seem to be lost without it. A clear example of the technical addiction is the use of the PC.
So far laptops and notebooks are the cutting-edge achievements in the field of computers, and they are undeniably conquering more users every day. When talking about laptops, which are also called notebook computers, we actually imply small PCs for mobile use.
We can virtually retrieve all the basic components in laptops from desktops. Thus, laptops have a display screen, a built in keyboard, a pointing device replacing the mouse and a battery power source.
The advantage of laptops is that they make one single unit that comprises all the other items, allowing for easy maneuvers and lots of mobility. The rechargeable batteries of laptops get their power from an AC/DC transcriber and their capacity enables them to be functional for several hours.
The very name of notebooks comes from the thin shape and small sizing of these computers. Laptops are usually 0.7 ? 1.5 inches thick and their dimensions range from 10×8 inches (13 inch display) to 15×11 inches (17 inch display) or up. Furthermore, they are not heavy, weighing between Iii and 12 pounds.
The design of most laptops as the flip form factor, is meant to protect the screen of the computer when it is closed.
Personal computers became feasible at the beginning of the 1970s and not long after those years the idea of portable PCs ? laptops, appeared. The person who imagined this was Alan Kay of Xerox PARC. In 1972 he put his idea on paper under the name of Dynabook.
By 1981, the first laptops were introduced on the market. The Osborne 1 and then, in the same year, the Epson HX-20 were the first portable computers commercially available. Since then laptops have developed and become more and more proficient.
Unfortunately, besides the obvious advantages of laptops, there are also some disadvantages. First we need to see the good parts to be able to investigate the flaws. The main and most important advantage of laptops is evidently their portability. In addition, laptops have the ability to work on battery power in the event of a power outage.
Furthermore, laptops use less electricity and generate a lower amount of heat as compared to desktops. Compatibility and standardization are the main flaws of laptops today. In spite of some accepted world standards for the making of the elements for the peripherals and add-in PC cards in backcloth computers, the internal components are a lot more difficult to standardize according to a unique international code.
