  • O Handheld Computer Wireless Data
    1,100 words
    Hardware Systems Many technologies are available to a business looking to create their own digital data. Nevertheless, some things must be well thought-out before buying equipment or software. The deciding factors of what will work best for an organization are dependent on the organization's current software, budget, skill-level of employees, available time, available data, and amount of data in need of digitizing. Because the process of data conversion, collection, and creation is often the cos...
  • Checks Data
    2,432 words
    Security of data Security of data involves the protection of data from anything that could destroy it, or introduce errors to it, as this may corrupt data. Things such as hazards, for example fires and floods, or another person gaining access to the data and damaging it, can destroy data. The security of data is very important, as many people store extremely important documents on their computers, for example bank or health records which may contain personal and confidential information about a ...
  • Second Generation Computers
    1,537 words
    The era of the First Generation computers began around 1945 and ended around 1957. These Machines featured components such as vacuum tubes, drum memories and had to be programmed in machine code. (That is the 1's and 0's computers understand) The Second Generation computers began around 1957 and ended around 1963. These computers had components such as transistors instead of vacuum tubes, magnetic core memories and higher level programming languages called assembly code was introduced. Third Gen...
  • Important The Use Of Computers In Chemistry
    832 words
    The Role of Computers in Chemistry Over the last few decades, the technology of computers has improved in leaps and bounds. Computers have become faster and easier to use, taking milliseconds to do the calculations which once had to be done by hand. There are several areas of chemistry where computers have played a significant role, a few of them I will discuss. In synthetic chemistry it is very important to know what compounds you have created. Chemists rely on spectroscopic techniques to analy...
  • Network Computers In A Single Line
    1,162 words
    The shape of a network can take many different forms and these topologies can be connected by a variety of means. The differing topologies are Mesh, Bus, Ring and Star and each one will be examined and the advantages and disadvantages explored. These networks can be connected via Ethernet, Token Ring, Fiber Distributed Data Interface (FDDI) or wireless. Each of the connection methods will also be analyzed and the differences will be explained. The term network topology refers to the physical lay...
  • Situation A Touch Input Device
    1,041 words
    Computers can be intimidating. Educating oneself about some of the basics of computers can lessen this intimidation. In addition, a computer user will be able to get the results that he or she is hoping for. Input devices, output devices, storage, and computer speed are a few areas that will be discussed further. In order to maintain accurate records or create precise results, data input should be done with the best possible input device. I will give examples of a few situations and explain whic...
  • Optical Disk Drives Use Lasers
    835 words
    Even before the first computer was conceptualized, data had already been stored on hard copy medium and used with a machine. As early as 1801, the punched card was used as a control device for mechanical looms. One and one-half centuries later, IBM joined punched cards to computers, encoding binary information as patterns of small rectangular holes. Today, punch cards are rarely used with computers. Instead, they are used for a handful of train tickets and election ballots. Although some may fin...
  • Computer Information
    1,063 words
    Over the last 10 years, computers have increased in speed and capacity while decreasing drastically in price. Computers that where once used in the corporate environment, are now slower than typical household computers. While this change occurred, telecommunications have improved to allow computers to communicate easily from remote locations, adding great opportunities for illegal activities. Data can be changed or destroyed, systems can be made to malfunction and long distance charges can be av...
  • Inputs Data Into The Computer
    1,862 words
    Computers The Computer that you know these days is a small thing that sits on a desk in your room that is composed of a monitor, keyboard, mouse and a small box. But computers have changed so much that if you seen old computer you would never recognize it. The first computer was built in the early 17 hundreds. You probably heard that the first computer was made in the 1950's but computers have been around for hundreds of years. All a computer is is something that calculates number. So these comp...
  • Test Administration And Interpretation
    584 words
    There are numerous benefits of computer-assisted testing. They can enhance test administration, scoring, interpretation, and integration. Test administration and scoring may be enhanced due to the standardization that is built in to computers. Another benefit is that each test taker receives the same presentation of test items and response sets. The availability of computerized testing devices allows people with a disabilities to complete tests with minimal assistance. This allows the test resul...

    ~Computing Through the Ages~"That's what's cool about working with computers. They don't argue, they remember everything and they don't drink all your beer", (Paul Leary). From the Abacus (16th century counting devise) to the laptop, auto computing has always been a desire for us humans. We are lazy, and we like to take the easy way out of problem solving. This is why we pay so much for someone, or something to do the work for us. Hence the computer. We " re going to start with the use of electr...
