The purpose of this paper is to explain the importance of accurate data input, the quality of output, and the use of different storage devices. This paper will shed light on which device is the best to use and when to use it for data storage. Another element to be discussed is the role of RAM, of clock speed, of a hard disk, of a CD ROM, and of a floppy disk and how each device determines computer speed. Through examination and exploration of each area one will achieve a better understanding of the importance of data input, data output, the advantages/disadvantage of storage options, and computer components.
Accuracy of Data
Printed Questionnaires – Scantron –an accurate because when people fill in the bubbled area it makes it easier for the computer to read the data and the results are computer generated.
Telephone Survey – Data Entry – because when a service representative is on the phone with the customer they would need to be use the computer to enter the data. This way when each question is asked the response can be computed at the same time and be saved in a secure document.
Bank Checks – encoding and routing numbers – because each number is linked the individuals account. There shouldn’t be two identical account numbers this way any confusion.
Retail Tags – bar codes- because bar codes can identify the item, price, department, and can also be used to track inventory.
Long Documents –Scanned and Photo copied – because it would reduce typing of the same document. For example, a scanned document can be uploaded to the computer in a matter of seconds, then emailed or faxed out. Making it a recorded document same as the original.
Convenience and Quality
Hand Held Computer – such as Palm Pilot, PDA, Blackberry, I Phone, you can send and receive in a matter of minutes by using text messaging, emails, printing, pictures, video, then you can also connect them to you home or office computer and download the stored information.
Color Photograph – Several methods such as: printing and scanning, are optimal options however, for convenience and quality a program such as: Picasa is a good program to use because it allows you to store and organize all your photos, allows you to edit, allows you to email, and allows you to print from your storage device.

Memorandum - although printing is a convent way to post necessary information, the fax and email are the best and fasted way to send the memorandum quickly and accurately.
Statistical Report – It would depend on the use of the report, for example, if it is being used for a presentation the best way would be to use a program similar to Power Point. By presenting the information in a presentation format this will allow many individuals access to the reports and will allow the presenter move forward and back quickly and conveniently without delay. Email would also be a great way to share the information with others.
Company Annual Report – Email would also be a great way to share the information with others and a printed document would work also.
Storage Devices
Hard Disk – the optimal situation for this device is to store the operating system for your computer. This device is a non-volatile which stores the data like a filing cabinet. This also allows a computer user to store their, documents, files, pictures, and other programs.
Floppy Disk – Floppies as they were called back in the day were use to store data, 3.5 were used say with the first computers, they moved up to 1.44floppy drive. They were the primary use for storage. They were mostly used to store data or back up programs say for example check disk or startup boot disks for an operating system. The only drawback became when they couldn’t hold enough information.
Ram- with out ram a computer would not boot up, Ram is volatile which means it is short-term memory and lost when the power is shut down. The more ram you have installed on your computer the faster it allows the computer to open programs, ram works with the CPU. It is used with random data.
CD Rom – great to use when downloading a program such as an operating system, listening to music, viewing pictures and using other types of programs. This device is also used to install programs.
Tape – is similar to a floppy drive or disk drive and is used to store or back up information.
Flash/Jump Drive – these devices are convenient and compact they hold a lot more data today. Some even have their own operating system stored on them to view various programs. Great for the transfer of school work, data information, pictures, music, etc.
Roles of the Computer Components
RAM - the higher the RAM that is installed on a computer will allow the computer to run several applications at the same time. It allows you to work with several open windows and programs at the same time. The more the ram the computer has the faster the program can run with another, ram works in conjunction with the CPU (eMag 2008).
Clock Speed – is the speed of the CPU, It is measured in MHZ. A setting in which manufactures preset the computer. It is the measure of how quickly the computer completes basic operations (Media 2006).
However, some people are known to over clock the computer to get more speed out of the CPU processor.
Data on a Hard Disk –the data on the disk doesn’t matter as far as the speed. What does impact the speed should be the speed of the Hard Disk, say for example a hard disk with 7200RPM, would slower then a 10,000 RPM Hard disk.
Data on a CD Rom – data is not stored on the CD Rom; it is stored on the CD disk, which the CD Rom writes to. The speed of the CD Rom will determine how fast the data is written to the CD.
Data on a Floppy Disk – floppies have a low rotation speed so they would affect the speed of the data transfer (United 2008).

I found the subject matter interesting. While writing and looking up information I learned many new concepts related to data input and accuracy of recorded information. During exploration I learned of many different storage options available on a computer. Another important aspect this paper examined is the role of computer components. Finally, I have become more familiar with computers, and some of the terminology associated with them.
