...Norah Stanley NT 1110 July 12, 2014 INPUT AND OUTPUT DEVICES Chapter three of the textbook Computer Structure and Design is all about the different types of input and output devices that are found on many laptops and desktops. Input and output devices are ports that transfer information. Some examples of input and output ports are USB, HDMI and Network ports. I will discuss their functions and where they are located on the Dell Inspiron 3542 laptop. One of the most popular ports I use is the USB port. USB stands for universal serial bus. The three types of USB ports are USB 1.1, USB 2.0 and USB 3.0. Each port transfers data but at different speeds. The USB 1.1 ports has a top speed of 12 Mbps. The USB 2.0 has a top speed of 480 Mbps. The USB 3.0 has the fastest transfer speed of 4,800 Mbps. The Dell Inspiron 3542 has three USB ports. On the left side of the laptop, there is one USB 2.0 and one USB 3.0 port. The right side of the laptop has the other USB 2.0 port. Another port that is used to transfer information is the HDMI port. HDMI stands for high definition multimedia interface. The HDMI port and cord are used to transport digital video and audio from one device to another. Many smartphones, tablets, dvd and blu ray players laptops, high definition televisions, computer monitors and cameras have an HDMI port. Most of the electronic devices I mentioned usually come with one HDMI port. High Definition televisions are equipped with two or three...

...comes with everything you need to start. In Windows, many printers can be installed by connecting the printer to the computer and then letting PNP initiate the installation. Another option is to connect the printer and use add hardware wizard. However, if an installation DVD/CD-ROM comes with the printer the best approach is to insert the DVD/CD-ROM and follow the instructions. Finally, another alternative, if you need to perform a manual installation or to initiate automatic detection and setup of a new printer, is to use the “add a printer” control panel option. One of the ways you can find out in windows what printer is installed on the computer is in “devices and printer”. You can access this by going to start, click on the control panel, from there a window will pop up, click on hardware and sound, double click on devices and printers. You can add a printer in the add a printer tab. Once you hit the tab, the computer will ask you how printer is connected to the computer for example: “USB, wireless etc”. You will choose the driver that correspondence...

...Input-Output Devices in Aviation David Campbell Embry-Riddle Aeronautical University Computer input-output technology is being used increasingly more in the aviation field every day. This is especially true for communication between pilots in the air, and air traffic controllers on the ground, allowing them to communicate through text messages. Previously, the only way to communicate was by talking over the radio on VHF frequency. This technology is a great benefit to pilots and controllers reducing their work load. But some challenges lie ahead to fully integrate this system. Europe has been using this technology for a few years now while the United States is just recently out of the testing phase to implement this technology. (Eurocontrol.TV, 2010) The flight data processing system in Europe is trajectory based, and is constantly being updated throughout the flight. This gives flight controllers the most up to date information and gives them the ability to predict workloads for various control sectors. This technology allows controllers to view instrument data from the cockpit in real time. Commercial aircraft in the United States has just recently started using the global High Frequency Data Link (HFDL) network as a means to communicate with ATC. This gives controllers and pilots the ability to exchange text and data messages over a long range utilizing high-frequency radio signals. (Keller, 2012) “FANS is short for the Future Air Navigation System...

...can be input in several different manners. Data may be input through a keyboard which is a device that allows the user to type the information directly into the computer. The keyboard is the most common and most utilized input device. An example of when the keyboard would be the best input device is printed questionnaires. Answering a questionnaire or conducting a telephone survey could be accomplished quickly and easily by simply typing the necessary information into the computer. Bank Checks are best entered by utilizing scanning technology similar to barcode scanners which are used on retail tags. A scanner reads the bar code and enters the information which the bar code represents. This method eliminates human error and insures the information is entered correctly. If it is necessary to input a long document, an optical scanner is the best choice. The optical scanner scans the entire document, page by page, and sends the document to a file folder for storage on a computer or storage device or to a printer if a printed copy is necessary. This method is fast so it only takes a few seconds to scan a long document into a computer file. Convenience and ease of use is important in for output devices. Hand held computers output information through visual output to video monitor or screen. Photographs are best input utilizing files such as JPEG and a scanner. Resumes and memorandums may best be output to a printer of email. Statistical reports could best be output by using...

...What is the meaning behind Computer Input / Output Architecture and Organization? Input is the entering of data into a computer system, whereas output is the transferring of data to an external item, such as printer. “The input /output modules are the third critical element of a computer system. The CPU and Memory are the first and second most critical elements.” (C.A.O). “The computer system’s Input /Output architecture is its interface to the outside world. This architecture is designed to provide a systematic means of controlling interaction with the outside world and to provide the operating system with the information it needs to manage I/O activity effectively.” (C.O.A.L). There are three main techniques for I/O, which are Programmed, Interrupt-Driven, and Direct Memory Access (DMA). These three techniques are essential for I/O. The Programmed I/O happens under direct and continuous control of a program requesting the operation. The Interrupt-Driven is when a program issues a command and continues to execute, until it’s interrupted by the hardware to signal the end of the operations. Finally, the DMA is when a specialized processor takes over control of an operation to move a large block of data. All three play significant roles in the architecture of the I/O in a Computer. An organization will have to have a large inventory of assets for just the basic Input Devices, Output devices, and both Input/ Output Devices related to the architecture of a company. A company...

...Structure and Logic June 29, 2015 Module 2 Short Answer I/O devices are a vital part of any computer system. These devices enable the user to put data into the system (input) and receive a visual representation of what they put in (output). Some of the most vital I/O devices to make a system operable are the most common seen. One such device being the monitor. The monitor is the single most important output device to have on a system. The monitor allows for a visual display of all inputted data on the computer. Paired with the monitor, the keyboard and mouse are 2 input devices which allow the user to directly input data and various other information into the system. However, there are some input devices which are not necessary for normal use of the system. One such example being a webcam. Webcams allow for visual input into the system but is not vital for system functionality or performance. Due to the fact that a visual input device is not a normal form of input for a system. A modem is considered an I/O device for a variety of reasons. A modem allows for data input to the system directly from the internet and other systems, as well as allowing the system to output data to other systems. Another device that follows the dual functionality aspect is a printer. The printer is viewed mainly as an output device, allowing for data to be visually outputted to paper. The printer can also be considered an input device, depending on what type of printer you have. Currently printers...

...Abstract My understanding on IPOS (Input Output Processing Storage) A computer is an electronic device, operating under the control of instructions stored in its own memory, which can accept data (input), process the data according to specified rules (process), produce results (output), and store the results (storage) for future use. The IPOS cycle happens every time you use a computer its stands for Input, processing, output and storage. These are the steps in the IPOS cycle. First input is entered into the computer through an input device, second, the CPU (Central Processing Unit) of the computer processes the information. Third the computer can output the information as a finished product or forth it can save it in storage for a later use. Output devices are continuously changing as technology advances. The IPOS cycle is the process the computer goes through to receive input, process the data, output a display of the results and storage store the information for a later use. An input device like a keyboard enters information into the computer. An output device like a monitor displays the results or information from the computer. Storage device act like an input/output device with the additional quality of saving data to use at a later date. Input is anything we wish to embed in a system for some type of use. It is any type of data or instruction used by a computer. It is the process of sending information to the computer’s CPU (central processing unit). Different...

...business and personal life. In one’s personal life individuals use personal computers, cell phones, and other electronic devices to store and carry personal information. In the business world, information systems have become essential to the smooth, ceaseless operations associated with business. Regardless of the department, one works in accounting, marketing or human resources, understanding and using information systems properly is essential to one’s personal and business success. The information systems used in accounting are a complex combination of modern technology and traditional accounting restraints used to provide the necessary financial information to manage an organization. Benefits of computerized information systems in accounting include speed, and accuracy. However, the system also possesses disadvantages including less documentation, and complicating the process of determining where errors occur (Grudinsku & Burch, 1989, p. 325). The primary components of accounting information systems include input devices, processing, and output devices. Common input devices include computers, scanning devices, and data entry. When working with accounting information the “double entry” model of the fifteenth century is still in use today. Typical output devises include printers, computer monitors, and electronic communication devices. Together these devices are used to manage and track debt collection, finances, and analyze profit, and loss within a business. In the marketing...
