Abstract
Different types of devices, for data entry and data output are evaluated and discussed. The effects of storage devices such as CD ROMS on apparent throughput of data in a system are evaluated.
Devices for Data Entry
Data Entry
Methods of data entry or input are many choosing the right method affects the accuracy of that data that is input. In the case of printed questionnaires, optical character recognition (OCR) devices and software can be implemented. Recent OCR technology has increased the accuracy of turning handwritten data into its digital equivalent.
Telephone surveys are best collected by data entry personnel typing the data into a keyboard in real time. Voice recognition can be used to collect essential survey data and pass it onto the data entry clerk to speed along the process.
Banks process their checks rapidly by using magnetic ink character recognition (MIRC). Magnetic ink is used to hold account data and verify authentication. This magnetic signature is easily and rapidly processed through machines that read MIRC on a mass scale.
Retailers can use tags with barcodes which hold the corresponding Universal Product Code (UPC). Used to facilitate a rapid checkout method for clerks and their customers, this data entry method also helps management keep accurate figures on inventory and sales related data collection to help the retailer make good business decisions.
Long documents are best copied by using scanning devices and software. Making exact copies removes human error and is also quicker. Once in digital format these documents are less cumbersome to deal with and can be easily edited.

Hand held computers should be able to connect to a desktop to transfer files or shuttle files from the field to the office for printing and viewing.
Printers are great for many things but must be accessed for particular duties they will have. Color photographs can be output on printers but color photo printers are best but specific in nature. Most standard printers are more than decent for rйsumйs and memorandums.
Statistical reports and annual company reports are best served by workstations. Workstations are more geared toward business applications and are built to handle heavy workloads.
Storing Data
Hard disks are the mainstay of any computer storage system. System software and the operating system are usually prenatally stored here as systems need these to operate.
Hard disks are now days extremely large pushing a terabyte of storage one just one unit. In the past years reliability has risen greatly. Hard disks are just the work horse
