...Shawn Saint-Germain NT1110- Computer 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...

...Understanding the BIOS and POST Abdus-Salaam Sabir NT1110: Computer Structure and Logic_ Module 5_Short Answer August 22, 2015 Darius Banks Understanding the BIOS and POST Why is it necessary to use ROM for the BIOS and not RAM? The basic input/output system (BIOS) is an essential component of the mother- board. This boot firmware, also known as System BIOS, is the first code run by a computer when it is booted. It prepares the machine by testing it during boot- up and paves the way for the operating system to start. It tests and initializes components such as the processor, RAM, video card, magnetic disks, and optical disks. If any errors occur, the BIOS reports them as part of the testing stage, known as the power-on self-test (POST). The BIOS resides on a ROM chip and stores a setup program that you can access when the computer first boots up. From this program, a user can change settings in the BIOS and upgrade the BIOS as well. It is necessary to use ROM for the BIOS because the data in the RAM is cleared when the computer shuts down, but the data in the ROM is always there for the BIOS to use. The BIOS is typically placed in a ROM (Read-only memory) chip that comes with the computer. This ensures that the BIOS will always be available and will not be damaged by disk failures. It also makes it possible for a computer to boot itself. Read-only memory is computer memory on which data has been prerecorded. Once data has been written onto a ROM chip,...

The Control Panel for Windows7 on a Network Control Panel for a PC Control Panel The Control Panel is a part of the Microsoft Windows graphical user interface which allows users to view and manipulate basic system settings and controls via applets, such as adding hardware, adding and removing software, controlling user accounts, and changing accessibility options. Additional applets can be provided by third party software. The Control Panel has been an inherent part of the Microsoft Windows operating system since Windows 2.0, with many of the current applets being added in later versions. Beginning with Windows 95, the Control Panel is implemented as a special folder, i.e. the folder does not physically exist, but only contains shortcuts to various applets such as Add or Remove Programs and Internet Options. Physically, these applets are stored as .cpl files. For example, the Add or Remove Programs applet is stored under the name appwiz.cpl in the SYSTEM32 folder. In recent versions of Windows, the Control Panel has two views, Classic View and Category View, and it is possible to switch between these through an option that appears on either the left side or top of the window.

...NT1110 Computer Structure and Logic Short Answer 2.1 Input/Output Devices Professor Mo Suleiman October 4, 2014 In the wonderful world of computers, we need to tools to communicate with a computer. Of course, a base foundation is the Operating System. However, we do need tools that will allow end users to streamline a computer’s full potential and functionality. That is where input and output devices come into play. In computing, input and output devices refers to the way we as end users communicate with a computer. Input is defined as a way the data or information sent to a system, as in typing something on a keyboard. Outputs are the signals sent by the computer system to the outside end user. An input device is a piece of hardware that transfers information or data in the world for consumption from an end user to a computer. Critical input devices needed to communicate with a computer are a keyboard, and mouse. A keyboard is the sole way to input keys, or command instructions to a computer. Without a keyboard, a computer is useless to an end user. Another critical input device is a mouse. A mouse is a click and point device used to manipulate GUI interfaces within an operating system. A mouse is not necessary in sole computer programming, but in order to manipulate GUI based operating systems and programs, a mouse is needed to communicate to a computer. An output device is a piece of hardware a computer uses to communicate the results of data processing...

...Poindexter NT1110 Computer Structure and Logic I/O Devices 1/12/15 Mrs. Coleman What critical I/O devices are necessary to use a personal computer? Which ones are not necessary for normal day-to-day use and why? A monitor and a keyboard are the two I/O devices necessary to use a personal computer. The monitor is the most important output device. It allows one to see the information that is being sent out by the computer. You cannot send or receive data to or from a computer without a monitor. The keyboard is the most important input device. It is the primary method used to send information to a computer. Data entry cannot be performed without a keyboard. The keyboard can even be used to navigate the desktop if a mouse is not connected. A mouse, game controller, printer, and modem are devices not necessary for day-to-day use of a PC. You cannot connect to the internet without a modem. Having a mouse makes using a computer more efficient. Day-to-day use can still be achieved even without a mouse, game controller, printer and a modem. Why is a modem considered an I/O device? A modem is a device connected to a personal computer and other computers via a network through a telephone or cable line. I sends and receives information to and from servers connected to the network simultaneously. This makes a modem both an input and output device. Why may a printer be classified as an input device? The printer is essentially an output device. The computer sends...

The 1156 is the number of pins in the socket, its designed to take the 1156 pin processor. What processors is it used with? Intel Celeron, Pentium, Core i3, i5, i7, and Xeon What is its purpose on the motherboard? LGA 1156 socket allows the following connections to be made from the processor to the rest of the system. * PCI-Express 2.0 ×16 for communication with a graphics card * DMI for communication with the Platform Controller Hub (PCH). This consists of a PCI-Express 2.0 ×4 connection * FDI for communication with the PCH, this consists of two display connections * Two memory channels for communication with DDR3 SDRAM Basically the LGA 1156 socket connects the processor with the motherboard.
