C. THE LAPTOP
Portable computer or in English Laptop, notebook or Powerbook is a mobile computer that is relatively small and light, weighing in the range of 1-6 kg, depending on size, materials and specifications of the laptop.
In the 1970s, Alan Kay of the Xerox Palo Alto Research Center has a vision for a portable computer that does not require wires, about the size of a notebook. He called it the Dynabook. Kay's Dynabook belongs created with wireless network capabilities. And it started to work the wheel development of a portable computer that is actually what it is today.
In the era of 1979, William Moggridge of Grid Systems corporation created the first portable computer: The Grid Compass Computer 1109. Has 340 kilobytes of memory, a die-cast magnesium case and folding electroluminescent display a. Nasa buy a lot from him in the range of $ 800 perbiji, for use in the space program.
in 1983, Gavilan Computer produced a laptop computer that works well as MS-DOS in 8088 processor. Produced with 64K RAM, can up-grade to 128K. By asking around 9 pounds, has a touchpad / mouse next to the keyboard in front.
In 1984, Apple introduced the Apple IIc models. Apple IIc was a notebook-sized computer, but not the actual laptop. Has a 65C02 microprocessor, 128 kilobytes of memory and 5.25-inch floppy internal, two serial ports, mouse port, modem card, external power supply, and can be folded. The computer itself has a weight of 10 to 12 lb (5kg), but the monitor is a little heavier. Apple IIc has a 9-inch monochrome monitor and LCD panel optional. The combination of a computer / LCD panel has made a portable computer. Apple IIc marketed to the home and education, and reap success for about five years.
Other companies such as IBM, introduced the other laptops in the next year. The first portable computer was a commercial release of the IBM PC, unlike the Apple IIc, convertible PC is really a laptop computer. Such as Gavilan Computer introduced in 1986.
With the rapid technology advances Laptoppun Affected dampaknya.Laptop generation now has a variety of forms from small to large, from simple specifications to a very high specification
Current technological developments bring tremendous impact to the lifestyle of every person. Especially in the field of information technology in terms of both hardware and software. No denying computer development is quite impressive, formerly a computer that is only used for office purposes, now evolved into various fields such as design, gaming, and entertainment. At the beginning of the first computer is only limited in the table can be used alone or often referred to as the computer desktop (computer sits). With the continued development of human thinking and civilization, came the concept or the idea that computers are not just limited to use on the table, but should be used to move where (mobile).
Here is the beginning of phasing development of www.kaskus.us laptop cited are as follows:
This began the first phase of the idea in the 1970s by Alan Kay of the Xerox Palo Alto Research Center has a vision for a portable computer that does not require wires, about the size of a notebook.

In the era of the second phase in 1979, William Moggridge of Grid Systems corporation created the first portable computer: The Grid Compass Computer 1109. Has 340 kilobytes of memory, a die-cast magnesium case and folding electroluminescent display a. Nasa buy a lot from him in the range of $ 800 perbiji, for use in the space program.
The third phase in 1983, Gavilan Computer produced a laptop computer that works well as MS-DOS on the 8088 processor. Produced with 64K RAM, can up-grade to 128K. Weighing in at 9 pounds, has a touchpad / mouse next to the keyboard in front.
In the fourth stage of the 1984 Apple introduced the Apple IIc models. Apple IIc was a notebook-sized computer, but not the actual laptop. Has a 65C02 microprocessor, 128 kilobytes of memory and 5.25-inch floppy internal, two serial ports, mouse port, modem card, external power supply, and can be folded.
