Implementation Methods for Outputs


Printed Output : The most common medium for computer outputs is paper- printed output. Printed output may be produced on impact printers, but increasingly it is printed on laser printers, which have become increasingly cost-effective. Internal outputs are typically printed on blank paper. External outputs are printed on preprinted forms. The layout of preprinted forms is predetermined, and the blank documents are mass-produced. The preprinted forms are run through the printer to add the variable business data. •

Screen Output : The fastest growing medium for computer outputs is the online display of information on a visual display device, such as CRT terminal or PC monitor. While screen outputs provide the system user with convenient access to information, the information is only temporary. When the information leaves the screen, that information is lost unless it is redisplayed. For this reason, printed output options are usually added to screen output designs.

Point-of-sale Terminals : Many of today’s retail and consumer transactions are enabled or enhanced by point-of-sale (POS) terminals. The classic example is the automated teller machine (ATM). POS terminals are both input and output devi”ces. ATMs displays account balances and print transaction receipts. POS cash registers displays prices and running totals as bar codes are scanned, and they also produce receipts.

Multimedia : Multimedia is a termed used to collectively describe any information presented in a format other than traditional numbers, codes, and words. This includes graphics, sound, pictures and animations.

Microfilm : Paper is bulky and requires considerable storage space. To overcome the storage problem, many businesses use microfilm as an output medium.
