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 come multi-functional in the form of a printer and a scanner. This would turn the printer unit into an input device, allowing for the input of visual data from important paper documents into the…...

...In this lab, you will demonstrate the ability to examine and investigate the different types of motherboards and CPUs used in a computer. Required Setup and Tools Photos of motherboards and CPUs are provided in the lab worksheet. However, if possible, the case cover of a desktop computer should be removed in order to get a look inside the system at the motherboard. The system should be unplugged and off when this work is done. You also need access to the Internet for research. Use the Lab 3 Worksheet to submit your responses. Recommended Procedures Task 1: Examine the Motherboard Procedure * Examine the following motherboard. One interesting thing you will see is the use of two BIOS chips. The M-BIOS chip is the Main BIOS chip and the B-BIOS chip is the Backup BIOS chip, which is used to rewrite the M-BIOS chip if it becomes corrupted. (Refer to the high-resolution images for closer inspection.) * Using the Internet, locate information on the LGA 1156 connector. What processors is it used with? What is its purpose on the motherboard? * Known as Socket H2, the LGA 1155 CPU socket is used with Intel's “2nd Generation Core* i7/i5/i3 series” of desktop microprocessors codenamed Sandy Bridge. This 1155-circuit socket is a replacement of its predecessor – the LGA 1156 Socket (or Socket H1) – which mates with the Nehalem* processor. * LGA stands for "land grid array" the 1156 is the number of pins in the socket.

Nt1110: Computer Structure and Logic Module 5 Short Answer

...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,...

...Computer Structure and Logic Lab 1 12/17/2015 The computer I am working on right now has Windows 7 Installed on it. Windows 7 is not perfect. Some features are underdeveloped. For example when typing the cursor will move through the document. And some annoyances remain intact. But overall, the final version appears to be a worthy replacement to Windows XP. In window 7 you can take the Screen and split it into two. This is a great feature when you are writing a paper and doing research at the same time. To do this just click on the middle of the tab bar and drag left or right, then take your other screen and go the opposite way. In windows 7 you can now pin Icons to the task bar. For example you can pin chrome to your task bar, to do so open chrome, it will appear in the task bar when it does right click on it. Click on pin to task bar, now you have easy access to chrome. Windows 7 started the “Peak”. You can take your mouse and hover your mouse over an icon on the task bar that is active, when you do this a small screen pops up and you can see what is in that tab. Desktop Gadgets can be added to windows 7. You can add the Weather or even a picture slideshow to the desktop, just right click on your desktop and click on gadgets. Double click on the gadget you want and it will appear on your desktop. The desktop I am using has an Intel Core Processor the CPU is running at 3.30 GHz. It has 8 GB of RAM wish it had at least 16.

This operating system has been a favorite of multimedia designers, graphic artists, and musicians since the 1990s. Not more than 10% of the U.S. population uses the Mac OS. Mac OS uses its own web browser named Safari as opposed to Internet Explorer. Linux is an ever-expanding group of operating systems that are similar to Unix in their design. Linux was designed as an alternative operating system to Windows.However Linux has a much larger market share when it comes to servers and other computer devices. The command-line functionality in most Linux distributions is in-depth and well documented, allowing a user to configure, and troubleshoot, just about anything from within the “shell” or command-line.

Algorithms and Logic for Computer Programming

...Programming Solution Part 3: Array Structure Proposal Wayne Murray Algorithms and Logic for Computer Programming (PRG 211) November 14, 2011 Professor Sprouse Array Structure Proposal In my proposal from week two I would want to find the total number of units per patient for each procedure code billed by the doctor. A parallel array consisting of a one-dimensional and a two-dimensional array in this case would be a good way to solve this problem in a simplified code format. An array would also allow all the data the user wants to input to be stored in the program for multiple queries to be run without having to re-input the data. So this module of the program will allow the user to input all the different procedure codes billed the provider and return a units-per-patient statistic for the searched procedure code. Assuming the data that the user will input is all for the same provider, the following variables will need to be declared: the procedure code, the number of patients, and the number of units billed. Two arrays will be declared as well, one for the procedure code and one for the number of patients and units. The procedure code variable and array must be setup with a string data type since there are some procedure codes that have alpha characters. The number of patients and the number of units variables, as well as their corresponding array will be setup as integer data types. Since both of those variables are of the same data type they can be combined......
