Mainframes and Personal Computers

A dramatic transformation in the advancement of technology has continued to evolve since the 1950’s. As computers started out, they were very expensive to make, they were slow and the computers were very basic. Now in days people can carry computers in their backpack but in the 90s, the computers would take up a whole room. The reason their computers were so large was because they required magnetic drums to store memory for the computer and vacuum tubes as switches and amplifiers. Today, these devices are built into our computers and other time they made them more compact. Also, as time went on, we received faster and more advanced technology. We are still using computers from the 1950s today; they are just highly advanced versions of their

One of the microprocessors that were developed during the 1960’s was called Intel8742. The Intel8742 was an 8-bit microcontroller that had a central processing unit that run at a speed of 12MHz as well as having a RAM of almost 128 bytes. During this time it was known that computers were very much revolutionized in the size by making them smaller. The smaller the systems became the more production of newer central processing units were developed. Another system that was part of the newer version of central processing units is called personal computer systems.

By doing so, they were able to deliver quality and performance in hardware failure rates and performance as well as operating system stability and processing speed.

One of the main limitations that Personal Computers have is the sheer price of the parts, PC’s are expensive, and with the ability to constantly upgrade your system you can spend up to £2000 on a gaming pc with high spec hardware, another issue is that PC’s are not very portable due to the size of the overall system such as, the tower, the monitors, the keyboard and mouse and all of the

The PC industry is one of the most competitive industries in the world. The industry had started to develop fast in the 80 's when IBM launched its first PC series following which a number of "Clones" made their entry into the market. Along with these clones a number of smaller manufacturers also started entering the market. The reason for this emergence was mainly that IBM had conceded the rights to the 2 most important components of a PC i.e. the microprocessor and the Operating System to Intel and Microsoft respectively. This was due to their "Open Architecture" model. This caused the technology to be available to everyone.

The concept of computing has changed over years and continues to change even today. Earlier we had mainframes and computers that took entire rooms to process small amounts of data. These machines led to smaller servers and increased computing over with a much smaller physical presence.

As the number of pc’s increased through the American households its usefulness also increased. Although once used to do basic calculations the household computer was now able to do so much more in such little space. This was all possible due to the

Minicomputers: In terms of size and processing capacity, minicomputers lie in between mainframes and microcomputers. Minicomputers are also called mid-range systems or workstations. The term began to be popularly used in the 1960s to refer to relatively smaller third generation computers. They took up the space that would be needed for a refrigerator or two and used transistor and core memory technologies. The 12-bit PDP-8 minicomputer of the Digital Equipment Corporation was the first successful minicomputer.

The increased use of information and information systems has also created an increased dependency on this technology. The development of the personal computer in the late 1970’s – early 1980’s in itself was an emerging technology in its time. It provided the spark that set off a new revolution in technology and led to the

Many people have different experiences and ideas with and about computers, dependent on a variety of factors, including age and how far technology had advanced at certain points in their life. Some people are exposed to computers in the form of smart phones from birth, while others were born years before desktop computers even became standard household electronics. Most people are somewhere in the middle of those two. However, I was one of the people who was born prior to household computers and phones that did more than just make phone calls.

Almost everyone now a days has a computer, or uses them on a regular basis. When you are using a computer so much, and accessing the Internet all the time, sometimes you can slow down your computer, sometimes even get it to the point where it crashes, or on the rare rare occasion it will need to get a new operating system. It really just depends on how well you take care of your computer while you have it.

A personal computer (PC) is any general-purpose computer whose size, capabilities, and original sales price make it useful for individuals, and which is intended to be operated directly by an end-user with no intervening computer operator. PCs include any type of computer that is used in a "personal" manner. A personal computer may be a desktop computer, a laptop, a tablet PC, or a handheld PC (also called a palmtop). The most common microprocessors in personal computers are x86-compatible CPUs. Software applications for personal computers include word processing, spreadsheets, databases, Web browsers and e-mail clients, games, and myriad personal productivity and special-purpose software applications. Modern personal computers often have

Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.[2]Simple computers are small enough to fit into mobile devices, and can be powered by a small battery.
