Laptops are among the computers that have just entered the field of competition, so that the life cycle of this product dates back only three decades ago. Despite the short time that this group of laptops entered the field of competition, but The existence of this category has led to significant growth, which has been significant for the manufacturers of this device. Share this information about laptop history with your friends and relatives too.
Laptop history
If we want to tell you a little bit about the history of making laptops, we have to say that Alan Kai from Xerox was almost the first person to invent the design of a portable computer in the 1970s and make it available to others. . In his ideal design, he drew notebook-sized computers with the acronym Dynabook, which were easy to carry. These devices also had the ability to store all the information needed by each person.
Kai believed that these portable computers should be built in such a way that anyone could buy and use one for themselves. Kai’s ideas went so far as to even consider the possibilities and capabilities of a wireless network for the Dynamo Book. Despite such beliefs, Kai could not register his name as the first inventor of the laptop and achieve the necessary success in his work. Finally, the first laptop was made by an Englishman named William Magridge for Grid System Company in 1979. This computer had 340 KB of bubble memory and an electroluminescent display. The Grid invented no more than one-fifth the weight of the lightest utility computers, and NASA used it for the space shuttle program in the early 1980s.
After the invention of the first laptop, no laptop was able to compete in the market for a long time until in 1983, Gavilan Computer Company invented and invented a laptop with 64 KB of random access memory or RAM. Had given place. It also uses an 8088 microprocessor plus a touch mouse. The laptop had its own operating system and was accompanied by a portable printer, which weighed 4 kg and the printer weighed 6.4 kg. With all the available facilities, Gavilan failed in this project again.
The following year, in 1984, the main and most important computer industry company, the Apple IIc, was launched, which, although a computer the size of a notebook, was not considered a laptop. Apple had 128 KB of memory, a 25.5-inch floppy drive, two serial ports, a port for a mouse, a modem card, an external power supply, and a collapsible. It also weighed 5 kg and had a separate, heavy 9-inch monochrome display. Despite all the features mentioned, this computer was still relatively easy to carry and was well received during the period for working in homes and stores, and until five years later, the sales of this device were still at the top of sales. .
In 1986, IBM introduced its IBM PC Convertible PC, which, unlike the Apple IIc, was a real laptop with the same features as a real laptop. Like the Gavilan laptop, it used an 8088 microprocessor , but had 256 KB of memory, a 3.5-inch floppy drive, LCD display , parallel ports, and a printer series, and space for a built-in modem.
The personal computer was invented by IBM with a series of specially designed software, such as a text editor, calendar, calculator, and phonebook. It weighed about 4.5 kilograms and sold for $ 3,500. The success of this device was very complete and noisy. In a way, it can be said that at that time, it was considered the flagship of new business in the field of laptops. Toshiba then followed in IBM’s footsteps and strategies, followed by many companies with strong scientific and financial backing. Since then, many manufacturers have entered this field and each of them has contributed to the development of laptop technology within the limits of their ability and talent. It is better to follow us until the end of the article on the history of making laptops .
The structure and features of laptops
Laptops, like all computers, are commanded by a microprocessor, which is the command and command center of the computer. The laptop processor is selected or designed to have the lowest power consumption. In general, laptops have a screen that is approximately LCD. Their mouse is tactile and flat, yet for more precise tasks or those with regular mice, the mouse port can be seen and used in the corner of the laptop.
Laptops use AC power or batteries as a power supply, and the lower their power consumption and the greater the ability to store energy in the battery, the more practical the advantage for a laptop. Today, many ports are installed in laptops to connect laptops to the local network, telephone line, printer and other data transfer tools. In addition to the hard disk that sits inside each laptop except for some very small special laptops, peripheral drives compatible with other computers, such as floppy drives , drives, and read-only information or read-write, depending on the type of need. Very compact faces are placed on the laptop.
Some laptops also have only one side drive, but it is possible to add or replace that drive with another one. Hard disk drive, RAM, and other internal components of laptops are generally no different from similar components on other computers except in size. Laptop keyboards are typically similar to other keyboards and in some cases tactile.
The general appearance of laptops is folding, with one side of the screen and the other facing the keyboard and mouse. Other components, such as speakers and side drives, are embedded on either side, depending on the manufacturer’s design. The size of a laptop is normally measured by the size of its display. Lighter weight is also an important advantage that is highly regarded by buyers. Today, laptops are built in such a way that it is easy to upgrade them.
