Cookies can be cleaned at the users convenience. 3. (10%) All computers perform five basic operations. Name and define each operation. Include two examples of each. Input operation is external instructions that are put into computer data form. Two examples of Input would be a video camera and the videos another would be a keyboard and the characters that are used. Processing operations are preformed by the CPU in order to process data so that it becomes information. Two examples of processing would be the editing of images and the addition of sounds. Storage operation is completed using Primary and Secondary storage. Primary storage being temporary and holds data that would be waiting to be processed and Secondary storage being devices that permanently holds data. Two examples of storage would be a hard drive and a USB flash drive. Output operation is when information is pushed from the computer system. Two examples of output would be a printer and speakers. Communications operation allows the functions of input, output, storage and processing to be completed from a distant area. Two examples of communications would be modem and wireless router. 4. (10%) Define the term ergonomics. Why is ergonomics important when a computer is designed? What purpose does ergonomics serve in an office or home setting? What are the consequences of a
When the user begins to interact with the computer, the software being used will send out a system call that will specify a task that a hardware component must perform in order for the software to continue functioning and send further requests,
Hard Disk is a non-volatile data storage device that is used to store and retrieve digital information using platters (rotating disks).
Output hardware is components of or devices linked to a computer, which allow the computer to transfer information to another computer system or the user of a computer system (Kroenke – pg74).
ii) Processor I/O : Data may be transferred to or from a peripheral device by

The selection of the appropriate type of input device for an IS depends on the user’s workflow. If the user moves around a lot as a nurse does, for example, an input device that allows data entry while moving from place to place is ideal. Headsets with speech input are often used in a mobile work environment. An output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information-processing system (such as a computer) to the outside world. The most common output device is the screen of the visual display unit. The processor is continually addressing the screen to send it signals whenever the results of an instruction have to be communicated to the user. Other output devices include printers, faxes, and speakers. The function of these devices is to translate the machine’s response to a usable form for the user (Sayles, 2017).
Input devices is mainly refereed to devices which are used to t provide data to the computer system in order for the computer to process. Without input devices, a computer user would not be able to feed instructions to, or send and store information in, a computer. Some of the example of Input Devices are as following:
____ is an area of a computer that temporarily holds data that is waiting to be processed, stored, or output.

My signature indicates that this document represents my own work. Outside of shared data, the information, thoughts and ideas are my own except as indicated in the references. I have submitted an electronic copy through Blackboard to be scanned by TurnItIn.com. In addition, I have not given aid to another student on this assignment.
Instructions. Your responses should demonstrate your understanding the course content and your analysis and critical thinking; you are not expected to just reiterate what is in the textbook, but to integrate the information and apply it to the specific question. Proper APA style must be used for any citations and references that you use. Place your answers within this document directly below each question and submit the completed exam to your Assignments Folder as an attached MS Word document. Total exam equals 15 points.
In summary, input and output devices are an essential part of business today. It is guaranteed that whether a company needs to print questionnaires, give telephone surveys, print checks, manage retail tags, or write long documents, that there are I/O devices running behind the scenes. Without these devices, users would not be able to communicate with computers in an information
Input, output, and connectivity are some of the most important considerations to make when choosing a computer. Without input and output our computers would not be able to function as they properly should, therefore making decisions on these sections are an important part in choosing a computer. In my last paper I broke down the main operating factors to consider when shopping for a computer: CPU, auxiliary storage, and RAM. These were the heart of the computer, but now we have to decide on the functionality that can be represented through input and output options. Through this paper we are going to try and rule out the obsolete
Furthermore, it can be seen that digital circuits utilise the converted information in two forms, combinational and sequential circuits. Combinational circuits operate as functions of input, with a consistent input reliably resulting in a consistent output e.g. an input of 01 into a circuit results in a 01 output, this process will remain, whenever this input is put into the circuit the 01 output will result (Lin, 2003). Sequential circuits differ in that their output can be affected by previous inputs and future inputs through the utilisation of memory elements that store previous logic values (Schibli & Lee, 2015). This data retention is achieved through Flip Flops, memory elements capable of storing a single bit of information in binary form (Godse & Godse, 2009). When grouped these form Registers whose sole purpose is the shifting and storing of binary data (Bakshi & Godse, 2009). As seen in figure 1.2, output Z is a function of the External Input and the memory states. The ‘function of input’ is ‘saved’ into the state, with the next signal from the external input being affected by the new internal input (Sequential Switching
• Output devices return processed data back to the user or to another computer system. The printer and monitor are examples of output devices.
