Silberschatz and Galvin explained that one of the most important aspects of the operating system is the ability to multi-program. Part of the evolution in personal computer is the ability of the operating system to multi-tasking where different resources such as CPU, memory and peripheral devices are utilized effectively through a time sharing.
Such a device that changes the way we work, live, and play is a special one, indeed. A machine that has done all this and more now exists in nearly every business in the U. This incredible invention is the computer.
The electronic computer has been around for over a half-century, but its ancestors have been around for years. However, only in the last 40 years has it changed the American society. An early counting machine and relative of the computer can be traced back to BC. This device is known as the abacus.
Although ancient, the abacus is not archaic.

Jul 18, · Cosper (n.d.) stated that Personal Computer (PC) and the evolution of the operating system via personal computers started through the 70s and the 80s with the arrival of the Apple, and Microsoft operating systems. Microsoft Corporation, leading developer of personal-computer software systems and applications. The company also publishes books and multimedia titles, produces its own line of hybrid tablet computers, offers e-mail services, and sells electronic game systems, computer peripherals (input/output devices), and portable media players.
It is still used in math education and in some businesses for making quick calculations Long and Long 33C. This ancient device represents how far into history the desire of humans to use a machine for calculations goes.
Another early relative of the computer was created in the seventeenth century by Blaise Pascal, a French mathematician Long and Long 33C. Numbers were dialed on metal wheels on the front of the machine and the solution appeared in windows along the top Kindersley. All mechanical calculators used this counting- wheel design until it was replaced by the electronic calculator in the mids Long and Long 33C.
The next step involves a loom. In the weaver Joseph-Marie Jaquard invented a machine that would make the jobs of over worked weavers tolerable Long and Long 34C. His invention was known as the Jaquard loom.
Jaquards loom used holes punched in cards to direct the movement of the needle and thread Long and Long 34C. Later in the same century Charles Babbage stepped into the scope of computer history. Babbage was born in in British Teignmouth, Devonshire.
Nevertheless, in British scientists constructed the Difference Engine based on the designs of Babbage. The Analytical Engine was to be computer that could add, subtract, multiply, and divide in automatic sequence at a rate of 60 additions per second Long and Long 34C.
With the aid of a professor he got a job helping with tabulation of the census, a process that took eight years Long and Long 35C. This machine used cards encoded with data in the form of punched holes. Closed circuits, which indicated hole positions, could then be selected and counted qtd.
In addition, the machine represents the first use of punched cards as a set of operation instructions, an idea originating with Jaquard and perpetuated by the Analytical Engine.
The innovative Hollerith went on to form the Tabulating Machine Company.
For many years IBM marketed punched card machines mechanical computers only. All computers were mechanical until the mid-twentieth century. The years between the s and the s are known as the EAM Era.
More punched card devices were invented and added to equipment. This innovation led, of course, to more sophisticated capabilities Long and Long 36C. Inhowever, Dr.
Berry, invented the first electronic computing device. This was the invention that would set the course of the modern electronic computer into motion. Iowa State never patented the device and IBM claimed they would never be interested in an electronic computing device Long and Long 36C.Having presented briefly the structural characteristics of personal computers, we analyze the technological evolution of the central system, made up of the central processing unit (CPU) and random access memory (RAM), and the mass storage subsystem which represent the .
