Mainframe/Pc Evolution

Mainframe/PC Evolution The evolution of mainframe figuring to face-to-face cipher began with the invention of the mainframe for businesses and government use. The Personal Computer (PC) evolved from companies wanting the same information from scaled down version of the mainframe and reserved term. Though they both consist of info storage, exerciseors, input and output devices. However, they put one across their differences. Mainframes The mainframe was invented in the 1950s. One of the root mainframes was the Univac 1, which was delivered to the Census Bureau in 1952.It measured 25-feet by 50-feet and had a storage capacity of 1000 rowing or 12,000 characters (Lexikon Services, 1982). In the 1970s the mainframe changed with the development of UNIX operating musical arrangement (Rogers, 2010). A mainframe according to Vaughan (n. d. ), A mainframe is a continually evolving general purpose computing platform incorporating in it architectural rendering the essential function ality required by its target applications (par. 5). The Mainframe is a multi-user data storage and application computing schema.Mainframe systems chamberpot be a item-by-item mainframe unit or multiple mainframe units, depending on the outlet of users and uses, it is needed for. Information is entered in on a dumb terminal or workstation. The mainframe brush aside be in the same board or in another room and even on a different floor. The mainframe is known for its reliability and why companies are unforced to spend the half-a-million dollars or more for them. Mainframes have fast bus speeds, eminent stash speeds, geological fault detection, and error correction (Rogers, 2010). Personal Computers One of the first information processing systems to be considered a Personal Computer was the IBM PC in 1981.Others were invented from 1955. It consisted of a monitor, keyboard, and desktop base with diskette drives. It weighed 28 pounds. Companies were looking for a authority to down-scale and cut the toll of the mainframe system. The Personal Computer, according to Whatis. com is a personal computer designed for use by one person at a time (TechTarget, 2008, par. 1). In right aways terms it consist of a show unit, keyboard, mouse, tower or desktop that consists of a hard drive, memory, processors, female parent board, and other hardware to carry out its functions as a microcomputer.The cost of a Personal Computer has become affordable over the old age for an individual to purchase for home use as well as company use. The use of a personal computer varies in that it is utilize for company business, home computing, gaming, and has other opportunities for an individual computing needs. The PC has changed the bureau people do business, pay their bills, entertain themselves, and communicate. The PC heap process data, run programs and applications, become a database, and can be networked into other PCs and mainframes.The Personal Computer makes it easie r for smaller companies to achieve what spaciousr companies can do with mainframes. Pcs can be networked together can share the same information, store information, and work efficiently. The hand held PC provides for computing mobility, which provides for more productivity. PC and Mainframe Comparison The mainframe is a large, reliable, multi-user computing system costing millions of dollars. If a mainframe has any downtime, the whole system and users cannot work. The PC is a small, affordable, and single user microcomputer that an individual can buy.It can be used for business and home computing. It has similarities to the mainframe display unit, keyboard, processor, memory, information storage, and operating systems. Contrasts Mainframe operating systems are designed chiefly to optimize utilization of hardware. Personal computer (PC) operating systems support convoluted games, business applications, and everything in between (Silbershcatz, Galvin, &038 Gagne, 2009). The mainfra me is more costly than a PC. However, it is more reliable than the PC. The mainframe can process information a lot faster than a PC.It also has faster bus speeds and higher cache speeds. The hardware in a mainframe has error detection and error correction for less downtime (Rogers, 2010). The PC is smaller, cheaper, and a single-user computer system. Its uses include home, business, and entertainment purposes. The PC system is can easily be moved by one person, the Mainframe system takes multiple people to move it. finale The mainframe made way for the personal computer. In a large business setting a mainframe would be worth the price.The PC is continuing to evolve and is becoming smaller and more evolved as applied science advances. Even though they have their differences, each serves it purpose in todays society. References Blinkenlights Archaeological Institute. (1999-2007). Pop Quiz What was the first personal computer?
