Mainframe Computing ( Ibm Operator 's Console )

Mainframes are virtualization; it can run multiple operating system and application. A mainframe can handle multi-user operations responding according to the user’s request. Mainframes are popular for it security and reliability, an ordinary virus hardly affect a mainframe. a non-authorized user are unable to access the mainframe until the user is a granted permission to access.

The ENIAC was invented by John Mauchly and J.Presper Eckert, Jr.and built from 1943-1945. The ENIAC (Electronic Numerical Integrator and Calculator), often referred to as the first computer, was built to supply the need for faster calculations. It started the information age and led to the development of the first commercial computers (The ENIAC).

Subsequently, several disruptive innovations, at their inception, are not better than existing products – they are worse. Anyone who required a mainframe at the dawn of the Personal Computer age discovered that it was an underwhelming, disappointing alternative; yet, the improvements and iterations demonstrated by the product eventually expanded to capture those in the mainframe market. The initial prospect of fostering low-quality alternatives, thus, does not always live up to the best that

IBM was behind the inventions of the Automated Teller Machine (ATM); Floppy Disk; Electronic Keypunch; SABRE travel reservation system; PC; UPC codes; Dynamic Random Access Memory (DRAM);Watson Artificial Intelligence and Virtual Machine. (IBM Facebook, 2014)

The first desktop all-in-one personal computer was the HP 9830 (1972) the first known PC was IBM’s 5150 introduced in 1981. The PC was known for its CUI , it required the Disk Operating System (DOS) to operate it and it offered a broad list of business software solution such as word processors, spreadsheets, calendars etc.

Computer technology was well in the works before the 1980s, yet, it was in the 1980s that the leap to home computing was made and thus launched the careers of two of the most famous men in the computing industry, Bill Gates, founder of Microsoft, and Steve Jobs, of the Apple Corporation. However, it was IBM that won the race to producing the first personal computer. IBM introduced the first personal computer PC in August of 1991 (History of the PC). “The first PC was good but not spectacular (History of the PC). However, IBM used many third party developers and companies, which helped, make the IBM the preferred PC. The first PC ran off of Microsoft Dos operating system. This made the IBM easier to add features to, but also made it easier for other companies to come up with their own versions of the PC. Microsoft was not exclusive to IBM allowing room for competitors. Competition came from all different kinds of computer

Apple’s first computer was developed around the 1970’s. Since then they have surpass one of

IBM was founded in 1911. IBM (International Business Machines) is by far the world's largest information technology company in terms of revenue ($88 billion in 2000) and by most other measures, a position it has held for about the past 50 years. IBM products include hardware and software for a line of business servers, storage products, custom-designed microchips, and application software. ("What is IBM (International Business Machines)? - Definition from WhatIs.com," n.d.)

By 1953, IBM began operations. The computer chip followed in 1958 with the first interface arriving by 1964.

* In 1981, IBM entered PC market used Microsoft’s DOS OS and microprocessor and will be Apple best rival for the start on 1981. Jobs forced out in 1985.

IBM was already a big name in the market of mini, middle range and mainframe computers. The perspective and promising small computer market, greatly gaining ground due to Apple II and other few, was still a difficult task despite their multi-millionaire efforts.

The first ever computer was invented in the 1820s by Charlse Babbage. However the first electronic digital computer were developed between 1940 and 1945 in the United States and in the United Kingdom. They were gigantic, originally the size of a large room, and also need to be supply a large amount of power source which is equivalent as several hundred modern personal computers. The history of computer hardware covers the developments from simple devices to aid calculation, to mechanical calculators, punched card data processing and on to modern stored program computers. The tools or mechanical tool used to help in calculation are called calculators while the machine operator that help in calculations is called computer. At first the

During a press release April 7, 1964 IBM Board Chairman Thomas J. Watson Jr. announced this was the most important product in the company’s history. (unknown, IBM, 1964). IBM knew that this was a special system due to how the system support was on a wide array of applications and it was the first operating system to require direct-access storage devices. (Hosch, 2014) The system was so successful other manufactures start trying to reproduce a similar machine. The impact of this operating system goes without saying was a turning point in the history of operating systems, but what made this

The Multics operating system project undertaken at the Massachusetts Institute of Technology (MIT) in the 1960s was a novel and powerful approach that helped shape the subsequent course of computing technology. In particular, Multics served as the model for utility computing and the various kinds of on-demand software, platforms, and infrastructure services that exist today. Multics was the first instance of the cloud. Leaving networked computers inside, Multics also offered a novel approach to hierarchical file structures that served as a model for future security approaches.
