Mainframe/Pc Evolution

Mainframe/PC Evolution The evolution of mainframe ready reckoner science to personal cypher began with the invention of the mainframe for businesses and government use. The Personal Computer (PC) evolved from companies missing the same information from scaled down version of the mainframe and speechless final. Though they both consist of information storage, kneadors, input and output devices. However, they watch their differences. Mainframes The mainframe was invented in the 1950s. One of the runner 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 talking to or 12,000 characters (Lexikon Services, 1982). In the 1970s the mainframe changed with the development of UNIX operating arranging (Rogers, 2010). A mainframe according to Vaughan (n. d. ), A mainframe is a continually evolving general purpose computing platform incorporating in it architectural explanation the essential f unctionality required by its target applications (par. 5). The Mainframe is a multi-user data storage and application computing establishment.Mainframe systems rotter be a oneness mainframe unit or multiple mainframe units, depending on the tot up of users and uses, it is needed for. Information is entered in on a dumb terminal or workstation. The mainframe end be in the same direction or in another room and even on a different floor. The mainframe is known for its reliability and why companies are automatic to spend the half-a-million dollars or more for them. Mainframes have fast bus speeds, high up lay away speeds, fault detection, and error correction (Rogers, 2010). Personal Computers One of the first computers 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 instruction to down-scale and cut the co urt 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 nows terms it consist of a boast unit, keyboard, mouse, tower or desktop that consists of a hard drive, memory, processors, develop board, and other hardware to carry out its functions as a microcomputer.The cost of a Personal Computer has become affordable over the days for an individual to purchase for home use as well as company use. The use of a personal computer varies in that it is utilise for company business, home computing, gaming, and has other opportunities for an individual computing needs. The PC has changed the focal point people do business, pay their bills, entertain themselves, and communicate. The PC tail end process data, run programs and applications, become a database, and can be networked into other PCs and mainframes.The Personal Computer makes it easier for smaller companies to achi eve what extensiver 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 in the beginning to optimize utilization of hardware. Personal computer (PC) operating systems support composite games, business applications, and everything in between (Silbershcatz, Galvin, & Gagne, 2009). The mainframe is more costly than a PC. However, it is more reliable than the PC. The mainframe can process information frequently 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 cheer purposes. The PC system is can easily be moved by one person, the Mainframe system takes multiple people to move it. close 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 technology 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?
