History of laptops

The concept of portable computers designed, as more and more for a laptop that can run on the execution time and do it in different places made noise. The laptops were introduced was a little slow and nonspecific laptops, and as we see today. It was too bulky, too small, no hard drive, and everything has failed RAM or hard disk.

In 1981, Osborne Computer Company introduced the first laptop; the first named Osborne This laptop when not in use and closed, like a sewing machine locked. It was operated by an electrical connection to a laptop battery backup option. He had two disk 5 ¼ "floppy (located on the right and left of the screen) and a modem connection. The biggest drawback was that the sample was 5 cm wide and cannot see a limited to 52 characters per line.

Then in 1983, entered the mobile PC Gavilan. Built strange and screen folded over the keyboard when closed. He weighed 9 pounds, and will work with nickel-cadmium batteries in about 9 hours. Three years later, in 1986, published the Radio Shack TRS - 80 Model 200 The model is more compact, has a larger screen and more efficient power of the laptop battery and contains embedded software. People use this template to create simple documents and it was high tech back then.

A year later, in 1987, IBM launched its version of a laptop by dialling 5155 laptop. It has been two-sided 5 ¼ "diskettes and 640 KB of RAM. In 5155, however, does not support graphics and limited treatment information based on text.

In 1988, the Compaq SLT/286 who have overcome the barrier of the graphics. However, this model strongly weighing 14 pounds, a 1.44-inch-processor was '286 '. NEC is the struggle with NEC UltraLite weighs only 4.4 kg and has a total area of ​​11.75 cm (W) x 1.4 "(H) x 8.3" (D).

Macintosh in the mobile arena in 1989 with the around16 laptop that weighed 9.8 pounds and had inch, 640 x 400 TFT display. Compensation has been a year of operation approximately 10 hours with a lead-acid battery. These first notebooks later, the Macintosh PowerBook line and the line now MacBook.

First, the 1990s saw the fastest, most elegant machines with more memory, more ports and connections, advanced displays, and weigh much less and very comfortable to wear. The line of Apple Macintosh PowerBook and IBM ThinkPad has been the biggest competitors on the market for a laptop.

Now the company of new laptops with faster processors and more features packed into smaller packages and notebooks have indeed come a long way from Osborne 1981 model. Of the 90, the technology has contributed significantly to the improved performance of laptops. And lasting laptop batteries and huge hard drives now replace the laptop makes a serious competitor in the market for office. In the summer of 1995 marked a watershed in the history of the laptop. In August this year, Microsoft released Windows 95th was the first time Microsoft has put a lot of control of power management, the operating system. This move had a lot in simplifying and stabilizing certain key aspects of the laptop design.
