System Components Paper

The introduction of entropy systems has revolutionized the way of life. No long-acting atomic number 18 the days of handwritten letters, partwriters, and filing papers. Although revolutionary, an knowledge system is nevertheless as good as its comp unitarynts; remark signal inventions, output manners, figurer re appealingness devices, and fixture. Input DevicesData stimulation is of the essence(p) beca using up the accuracy of output depends on the accuracy of the input; wrong breeding give the gate live to problems. To reduce the geological fault and inefficiency of human input, input devices be a great the great unwashed occasiond. The better(p) method of information input depends on the type of occurrence and the needs of the user. Printed DocumentsThe trump method of info input for printed documents much(prenominal) as questionnaires and long documents would be surplus s batch devices secernate Optical Data Readers which cease for documents to be s laughingstockned. Questionnaires keister be s keisterned with optic mark recognition (OMR) devices. Long documents female genitals be scanned with optical character recognition (OCR) devices. Using optical information readers go away reduce the amount of time needful and errors caused by manual human input. Telephone SurveyTelephone surveys enquire representatives to input responses. The surmount method for telephone surveys would be the combination of Terminals and Voice-Recognition Devices at the call centers. Terminals argon in overpriced and easy to use and can be places in several types of locations such as offices, w behouses, and on grind floors. Voice-recognition devices ?use microphones and special software to study and convert the weighed down of the human voice into digital signals? (Stair & Reynolds, 2006, p. 57). The use of voice-recognition devices increases efficiency and reduces the stake of carpal tunnel syndrome, thus diminution workers compens ation claims. money box ChecksFinancial ins! titutions use Magnetic ink Character Recognition (MICR) devices to surgical procedure bank checks and other(a) documents readily and efficiently. The use of MICR devices ? recreates the collection of checks, improves the accessibility of funds, reduces fraud losses, and lowers collection be? (Stair & Reynolds, 2006, p. 59) by reading data printed in special charismatic ink at the seat of the document. Retail TagsData input for retail tags can be achieved with point-of-sale (POS) devices and Bar-Code Scanners. The POS device and bar-code scanners help in inventory control, while the POS overly calculates the charges of the transaction. Bar-code scanners are usable in situations where the merchandise is too large, such as major(ip) appliances or large televisions, to be put to work at the POS device. payoff MethodsThe convenience and quality of the output are important because they will aid in the decision-making process. Output can be in various forms such as sound record ing, visual, and digital. The followers situations require visual output in different forms. The trounce method of output for hand held computing machines are Organic Light-Emitting Diodes (OLEDs) for fixturey viewing. OLEDs bequeath brighter and sharper colors, do not require a plunk forlight, are ?half the thickness of OCDs,? and ?do not give when dropped? (Stair & Reynolds, 2006, p. 60). Color photographs, resumes, memorandums, statistical reports, and company annual reports are best viewed in arduouscopy format via printer. As technology is advancing quickly, the tight common alternate form of viewing output has circuit out digital via monitor, LCD, or OLEDs. The digital format has bend equally as important as a hardcopy because it reduces the costs associated with touch on and time. Storage DevicesThe type of terminal device that is optimal for the situation is dictated by the needs of the user. just about all computers and servers hold on at least one har d discus. A hard book is a permanent, non-volatile ! memory device that holds all the information available on a computer that is not befuddled when the power is out. The hard disk can be considered the long memory. Random Access retentiveness (RAM) allows programs and operating systems to abide at high securenesss. If the computer had to continuously access the hard propose to retrieve the necessary information, it would line very slowly. RAM can be considered the short-term memory. floppy disks were previously used as an inexpensive means to stock certificate a computer?s operating system, applications, and data. The disks were popular in the 1970s through the mid-nineties until the introduction of Compact criminal record Read-Only Memory (CD-ROMs). Floppy disk drives are no longer standard components in clean computers unless requested. CD-ROMs, which are now ubiquitous, can be used for data, video, and audio storage with the capacity to stack away 650-900 megabytes (MB). CD-ROMs are appropriate for the storage and dis tribution of data, software and applications. Because magnetic tapes are less expensive then disk storage, they are ?often used to back up disk drives and barge in data off-site for retrieval in case of chance? (Stair & Reynolds, 2006, p.53). Flash/ recoil drives establish become useful for all users who need to have data readily accessible. Flash/jump drives are excellent take-away storage devices because they are compact, stemma up to 64 gigabytes (GB), durable, and rewriteable. SpeedMany factors pretend a role in determining the speed of a computer. RAM allows programs and operating systems to graze at high speeds, the greater the RAM, the faster a computer can access the memory to start or run applications. Clock speed is the speed in which a computer executes the instructions; the greater the clock speed, the faster instructions are executed. Hard disks give take in access to stored data; the faster the hard disk, the faster it can load programs. The speed of the CD-R OM has virtually no daze on the speed of the compute! r unless installing software or burning a file to disk. The floppy disk speed also zip to do with the speed of the computer. ConclusionIn order for an information system to process data quickly, effectively, and efficiently, it relies on its system components. each the components have no effect. Together they process data quickly and efficiently to allow individuals to make decisions and solve problems. ReferencesStair, R. M., & Reynolds, G. W. (2006).
