It seems that in today's world nothing can be done without a computer, but upon a closer look, you will find that it is the hardware components and input and output devices that make a computer useful. What is it that determines the speed at which a computer can find a file? How do you get a report from your PC to the members of your next Board meeting? It is the hardware that is used with your computer that allows you to accomplish all of your business needs using your computer. Data input is the collection of raw data that is used to find needed information. Data input is an important part of any business, but different businesses have different needs when it comes to input devices. Some common business needs and the best data input solution to solve them are listed below: Printed questionnaires- An optical mark recognizer (OCR) would be best because it will read the answers chosen by the participant and turn it in to digital data. Telephone survey- A voice recognition device would be the best solution because it would allow the telephone survey answers to be converted for digital use. Bank checks- A magnetic ink character recognition device (MICR) is the best answer for banks because it was developed by banks to read a special magnetic ink with pertinent data to be converted in to digital information (Stair & Reynolds, 2006). Retail tags- For retail tags, bar code scanners allow for keeping track of inventory and for pricing and labeling. Long documents- Optical data readers are the best bet for allowing long documents to be scanned into digital data. Once a company has the input they need in digital form, they must have a tool that allows them to create high quality output of the information gathered. There are many output devices, but it is important to have the correct one for the job. Listed below are some examples of output and the best way to get it: Hand held computer- The best way to get output from a hand held is through the built in liquid crystal display (LCD) since there are no other built in output features. Color photograph- A color photo should be printed on a high resolution photo printer, or if it is a very large photo, a color plotter would be a good option. Resume- Since most resumes are printed at home, a personal ink jet printer is the way to go.
The first method I will look at is the rt method which is built upon collected data from surveys etc. Its main plus points being that it uses a much larger sample than the other methods because it takes less time to collate the results. It is also useful because it allows for further research to be added - it can be updated. There are a number of problems with this. The subjects may not feel comfortable and could answer just to please the experimenter. A big problem with the method is that it does not give enough range for the subject. They are restricted within the boundaries of the tick boxes. The researcher can only learn so much.
Printer – A printer is used to print different images from the computer that you want to, this could be important sop the user can print the image that they have created and they can scan it onto different hardware and make different items with this graphical image.
2. Identification. RFID tags also offer a much higher information density than bar codes, allowing manufacturers and vendors not only to store a generic product id...
There are many different types of student response systems. The most common student response system includes a set of handheld devices, otherwise called the input device, software to develop the questions and collect the data, and a projection system. Input devices come in three basic types with a variety of shapes and sizes. The first type is an input device that merely sends the student’s response to the computer software which collects the data, with no feedback to the students. The second type is an input device that sends and receives information, to indicate if the question was responded to ...
Computer hardware engineers research, develop, and test computer systems and components such as processors, circuit boards, memory devices, and many more (Bureau of Labor Statistics). They design new computer hardware, create blueprints of computer equipment to be built. Test the completed models of the computer hardware that they design. Update existing equipment so that it will work will new software. Oversee the manufacturing process for the computer hardware. Maintain knowledge of computer engineering trends and new technology(Bureau of Labor Statistics).
Obtaining information or rather measurements by a survey in this type of occupation would be one of the last type of methods that I would use. Simply and to sum up, not everyone answers or likes to complete surveys.
RFID data, for example, part and serial numbers, assembly dates and support history are put away on the tags and catches which help in maintenance of equipment. RFID technology as high value for asset management and inventory systems. A barcode is a visual representation of data that is checked and utilized for data. Bar code is simple to control equipment and tool inventory. In facilities supervisors can use barcodes to link work orders, purchase orders, spare parts and equipment which can be further used to track and collect costs.
Hand Held Devises a small LCD screen can easily and effectively provide a convient output. Just like having a Computer Monitor but smaller and lighter.
Building a computer can be a useful skill in today's world. It allows you to
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).
A processor is the chip inside a computer which carries out of the functions of the computer at various speeds. There are many processors on the market today. The two most well known companies that make processors are Intel and AMD. Intel produces the Pentium chip, with the most recent version of the Pentium chip being the Pentium 3. Intel also produces the Celeron processor (Intel processors). AMD produces the Athlon processor and the Duron processor (AMD presents).
The World Turning Digital: computer is seen in virtually all aspects of our lives. From the mobile phones we use, the Television we watch etc. Makes it pretty interesting to found out how this work.
Long ago, people were simple and didn’t have many technologies. They used to take so much time in planning their projects, researching, and saving and recording their studying. Look around, this world changed a lot. There are cars, airplanes, computers, and many other technologies. Technology can be found everywhere, and we use depend on it a lot. One of the most important technologies is computers and laptops. Many people use them today in their daily lives and it eases many things for them.
Computers are very complex and have many different uses. This makes for a very complex system of parts that work together to do what the user wants from the computer. The purpose of this paper is to explain a few main components of the computer. The components covered are going to be system units, Motherboards, Central Processing Units, and Memory. Many people are not familiar with these terms and their meaning. These components are commonly mistaken for one and other.
The central unit is the basic part of the computer and includes all the main computer parts. It is the heart of the computer system. It is responsible for executing, or running the software. The software programs are translated into a series of codes made up of 1s to 0s that the CPU can understand. Every code means a certain operation should take place.
