How Computer Technology Ties into Information Technology
This paper will show how computer systems are an integral part of information technology. We will look at: the best methods of data input for given situations, in given situations what are the best methods of output, the different types of storage and their optimal use, and how certain components affect computer speed.
Accuracy of Data Input is Important
Now we will look at five different scenarios and what would be the best way to input data and why. Printed questionnaires or surveys are often part of research studies so the method used to input their data into the system needs to be as accurate as can be. Human data-entry devices (HDED) would not be a very reliable form of data-entry because most research studies put out hundreds if not thousands of surveys and for people to try to input all that data accurately would be almost impossible. Since almost all surveys are multiple choice the best choice for the input method is the optical mark reader. The optical mark reader is a source-data automation input device (SDAID) that scans the survey detecting marks on the answer grid.
Telephone surveys are another changing part of society, in the past phone surveys were handles by multitudes of phone operators asking questions and typing the responses into the computer. Times have changed and companies are seeing that the time of the human phone operator is over, not only can they be slow at data-entry but it is also easy for their data-entry to be mistake riddled. Every day more and more companies are instead using automated systems which use voice-recognition software. This software converts and enters the human voice into the system as data, making data-entry significantly faster.
Magnetic ink character readers are SDAIDs developed to read the magnetic ink on things like bank checks. One quick scan inputs the information into the system instead of the much slower process of using a HDED.
Today retail tags like many other things have gone electronic by having barcodes. This makes the barcode reader the best device for dealing with the retail tag. By scanning the barcode the reader retrieve all of the information about a given product, the price, inventory, and even when to reorder within seconds.
Today everyone knows how to use a scanner or optical character recognition sensor. Scanner come in many different shapes and sizes that allow the user to quickly scan anything from an image to a large document and save the data into the system.
Convenience and Quality of Output are Important
Today is all about "convenience and quality", everyone wants the very best but they also want it to be in the most convenient form. The hand-held computer is a testament to this, the power of a computer in the palm of your hand. The ideal output for this is an organic light-emitting diode (OLED) display. This type of display is brighter and faster than LCDs which makes it the better choice, but it also lighter, cheaper, and runs on less power making it the most convenient choice.
Although inkjet printers may cost more in the long term to run they are still less expensive than laser printers. Most at home computer users are looking for the "most bang for their buck" and since these are the same users who are printing out their own color photos and resumes inkjet print are the best option for output. businesses on the other hand are willing to spend more in the beginning to save more in the long run, thus making the laser printer the best output device for company paperwork such as memorandums, statistical reports, and company annual reports.

Different Types of Storage Devices are Optimal for Different Situations
This section will discuss different types of storage devices and when it is best to use each and why. First we come to random access memory (RAM) which is a part of the systems primary storage. The RAM is a small, quick access, volatile form of memory that the system temporarily stores data or process instructions into for instant access.
The hard disk or hard drive is a much larger, nonvolatile form of secondary storage that can store billions of bytes of data and programs within its disks. Hard drives have the advantage of being small, fast, inexpensive, and have the ability to store enormous amounts of data.
The floppy disk, while at one time it was floppy, is a small external storage device to store small amounts of data that may be transported from one system to another as needed.
Compact disk read only memory (CD-ROM) has made it easier to move billions of bytes of data from one system to another in a small read-only format.
The flash or jump drive has once again expanded our ability to move and or share data between not only different systems but between different users as also.…...
