Data Input, Output, Storage and Access Methods The purpose of this paper is to highlight some best practices for data input and output. In addition, this paper will highlight appropriate uses of various storage means. Lastly, it will address the effect certain components of a computer have on its overall speed. Accuracy of Data Input There are various methods for entering data into a computer system. Depending on the medium in which the original data is contained, and how it is to be stored and used later, there can be great differences in input methods. Printed questionnaires, for example, would be best entered by re-typing the answers given. A voice recognition system may be best suited for surveys taken over the telephone as there are no other means to take input over a telephone. In the case of bank checks, image scanners can capture not only the handwriting and MICR numbers on the front, but they also can capture the signature of the party cashing the check, and the date/time stamp that was used at the time of payment. Retail tags could take advantage of barcode scanners as a means to input the data they carry. There are several data points on a retail tag such as price, color, size, manufacturer, etc. These all can be captured in a single bar code, allowing it all to be input at the same time. Long documents, such as house mortgages, pre-nuptial agreements and the like, are ideal candidates for scanning input as well. However, character recognition scanning software is probably more appropriate, so that instead of a ‘picture’ of the document, it takes the file format of an actual digital document (.doc or .pdf, for example). One data is actually entered into a computer, there is a means by which it must be extracted. Convenience and Quality of Data Output As there are various methods for data being put into a computer, there are also several means by which data output can be created and viewed. For example, a handheld computer’s output would best be via the device’s screen. The handheld is more of a convenience device that is rarely used for high quality documents or graphics creation. Color photographs are best put to paper specifically designed to accept photographic images and ink. For a resume, the best way is via a laser printer, for its sharpness, on to high quality bond paper for a feel of quality and professionalism.
1. Automation. While optical bar codes require a line of sight for readout, i.e., either careful orientation of tagged goods with respect to the reader, or manual intervention, RFID tags promise unsupervised readouts. This increases the level of automation possible, as tagged items do not need precise orientation during the readout process.
...radio frequency identification has been around more than 50 years and it has only recently received its well-needed attention. Radio frequency identification is a technology using radio waves to find and monitor objects, including goods and services in the supply chains. Walmart put RFID on the map by using it in their stores, vehicles and supply chain. RFID technology is only going to improve safety, convenience, and inventory management but widespread adoption in retail operations could take several years. The healthcare sector has already started to adopt RFID into their day-to-day work system. They are able to use the RFID method in many different areas to save time, money and more importantly waste. Barcodes and RFID work smoothly together as of right now but more companies and organizations will start to use RFID tags once cheap disposable tags are developed.
Although there are many technologies in tracking, for this research I will be discussing Radio Frequency Identification (RFID) and Universal Product Code. There are major differences and comparisons between these two technologies which define both. Though both of these technologies are widely used within numerous industries, they are used differently since they are so different. For example, the government (United States Postal System), military, private companies (such as Wal-Mart, Target and other companies), the healthcare system, and other industries all use these types of tracking technologies. Though some industries specifically use just one technology or though many use both. In my research, I will define both technologies, discuss the history, how they are used and what the future is of both products.
The Association for Automatic Identification and Mobility (2012) defines RFID as a universal term that is used to describe a system that transmits the identity of an object or person wirelessly, using radio waves. The function of an RFID system is to enable data to be transmitted by a portable device, called a tag, which is read by an RFID reader and processed according to the needs of a particular application (Association for Automatic Identification and Mobility, 2012). RFID tags are a small object that can be implanted or attached into products (clothing, shoes ect.), humans, or animals that enable storing and retrieving data possible. With no physical contact required, this type of data can be collected and read through clothing, the human body, and non-metallic materials. In recent years, RFID tags have been used in identifying animals for health or nonhealth reason...
Then go into Microsoft Word’s resume template (or on the Web) and print several different resumes the same way you printed yours. Spread them all out on a table. Does your resume appeal to you?...
In the using of IT, I will be able to type easily than the normal paper, for example, I will be able to re-correct my spelling mistakes using the Microsoft word while I can’t erase or correct using the normal paper and re-write it on the paper. Using the IT I will be able to link, do correction thousand words or replace.
Barcodes are very labor intensive as they must be scanned individually but RFID tags can read faster and with minimal human participation. Barcodes have less security than RFID as they might be easily hammer out and imitate. Barcodes works with same accuracy irrespective of...

The Von Neumann bottleneck is a limitation on material or data caused by the standard personal computer architecture. Earlier computers were fed programs and data for processing while they were running. Von Neumann created the idea behind the stored program computer, our current standard model. In the Von Neumann architecture, programs and data are detained or held in memory, the processor and memory are separate consequently data moves between the two. In that configuration, latency or dormancy is unavoidable. In recent years, processor speeds have increased considerably. Memory enhancements, in contrast, have mostly been in size or volume. This enhancement gives it the ability to store more data in less space; instead of focusing on transfer rates. As the speeds have increased, the processors now have spent an increasing amount of time idle, waiting for data to be fetched from the memory. All in all, No matter how fast or powerful a...
Barcodes are used everywhere around us. They are used to track products through shipment, track products at a store and speed up and enhance the checkout process, as well as allowing faster access to information. Barcodes began to be used heavily in the 1970’s. This began a great movement in the consumer industry, speeding up the checkout process and allowing easier inventory tracking. However, just like all technologies, barcodes have been enhanced many times over and are being replaced by better, more efficient systems (Bonsor).
The computer evolution has been an amazing one. There have been astonishing achievements in the computer industry, which dates back almost 2000 years. The earliest existence of the computer dates back to the first century, but the electronic computer has only been around for over a half-century. Throughout the last 40 years computers have changed drastically. They have greatly impacted the American lifestyle. A computer can be found in nearly every business and one out of every two households (Hall, 156). Our Society relies critically on computers for almost all of their daily operations and processes. Only once in a lifetime will a new invention like the computer come about.
Computers are one of the most popular kinds of electronic devices in the world today. Whether kid or adult, male or female, everyone wants to learn how to operate the computer. People use computers for different purposes such as typing papers, creating websites, making presentations, browsing on the internet, playing games, etc. In fact, many people are still confused about choosing what kind of computer they want to buy. In the world today, there are two types of computers: notebook/laptop and desktop. They both are actually very different in several ways. In this paper, I will compare the size, connectivity, power, and price of notebook and desktop computers. I can make these comparisons because I have both a notebook and a desktop computer in my apartment.
Computers are forever present in the workplace. Word processors-computer software packages that simplify the creational and modification of documents-have largely replaced the typewriter. Electronic mail has made it easy to send messages worldwide via computer communication networks. Office automation has become the term for linking workstations, printers, database system, and other tools by means of a local-area network. An eventual goal of office automation has been termed the 'paperless office.' Although such changes ultimately make office work much more efficient, they have not been without cost in terms of purchasing and frequently upgrading the necessary hardware and software and of training workers to use the new technology.
The input and output sections allow the computer to receive and send data, respectively. Different hardware architectures are required because of the specialized needs of systems and users. One user may need a system to display graphics extremely fast, while another system may have to be optimized for searching a database or conserving battery power in a laptop computer. In addition to the hardware design, the architects must consider what software programs will operate the system.
