...An I/O tool can be either inner (set up in the computer case) or outer (set up away from case). Inner tools may be expansion cards placed in expansion slots on the motherboard, for example a network card, audio card, video capture card, and video card. Outer tools include keyboards, screens, mouse, printers, scanners, and digital cameras. You may connect an external tool to the system utilizing slots coming off the motherboard (serial, parallel, USB, IEEE 1394, etc), or a slot can be supplied by an expansion card. But, for all these various tools, some fundamental rules apply to support each of them. These rules are applied in several places and are summarized here to get a look at them. Look into these basic rules and ideas used when supporting I/O tools: Each and every I/O tool is managed by some software items. If we set up a new I/O tool in our computer, for example a modem or printer, we should set up these tools and the drivers to manage these tools. These device drivers should be written for the OS you are using. For instance the keyboard, which is managed by the system BIOS or device drivers embedded in the OS. With regards to setting up or supporting a tool, the producer knows best. The I/O tools are set up prior to the device drivers which are set up in the computer since the device driver finds the device at the driver set up time (often when the I/O or peripheral device is initially plugged into the computer). Some application software is often needed...

...some instances, you may save some money, and in all instances you'll have accomplished a project that you'll benefit from for years—a pretty great feeling in and of itself. That said, building is much more time consuming than buying, and your first time through, it can be daunting. This week's Night School series will walk you through building your first (or second, or third) computer from start to finish. Today, we'll be talking about the first step in any computer build: brainstorming what kind of machine you're looking to make and what that means for your hardware. The Types of Machines and their Ballpark Costs Much like we did in our original spec-crafting feature, the the first thing you need to do is come up with a very, very rough idea of what kind of performance you want from your machine. The easiest way to do that is to split builds it up into three general categories: Low Performance: If you're looking for a simple PC for web browsing, email checking, or video watching, a low performance machine is probably the way to go. These machines are small, don't draw a lot...

...In the text Lions of the West written by Robert Morgan talks about North America in 1831 involving the issues such as westward expansion and why it was either a good thing or a bad thing. In the text Robert Morgan gives his own opinion about the westward expansion whether it was a good thing or not. Robert Morgan’s central idea will be supported by what other authors have wrote in their text.Coming from Chief Joseph Speaks…, Reporting to the President, September 23- December 31, 1806, The Way to Rainy Mountain. Robert Morgan’s claim “There Is No True History of the Westward Expansion” was not reasonable.

...Step 1 User boots her computer and hears a sequence of six beeps. Step 2 a cause could be an expansion card has failed. Step 3 you would do a physical check and uninstall and reinstall any expansion cards that you have connected to the motherboard. When you do that restart the computer and see if you get that same beep sequence or any. Step 4 you should check run a test on all expansion cards.Step 5 once you ran many tests and you fixed to problem you then verify the computer is working. Step 6 you found that the expansion slots were a problem and you replaced them with new ones. Now your computer is working fine. Step 1 the user boot their computer and hear a sequence of ten beeps. Step 2 a cause could be by a damaged expansion card. Step 3 after pulling the cards out you still has a problem. Step 4 you then replace the motherboard and that should fix the problem.

...power switch allows normal OS shutdown unlike the back switch, which immediately cuts power. Second is the NLX, which is for low end personal computer, supports riser card which adds expansion slots. Third is the BTX which is compatible with all ATX functions but is designed for better airflow and cooling. By having an intake vent at the front and an exhaust vent on the back along with having the CPU and memory modules installed parallel to the direction of the airflow, the BTX achieves its cooling functions. Communication buses are also explained. They are copper tracing on the bottom of the mother board and they make up the bus system. Often described as highways. Buses connect to various components and allows power and data between the CPU, Hard Drive, key board, mouse, USB devices, sound cards and any other components. System bus is the largest and fastest bus, it connects to the mother board and it carries data between the CPU and the mother board and vice versa. There are various connectors on a mother board one of them is the power connector known as the p1 connector. P1 has a 20 pin connector or a 24 pin connector. The 40 pin IDE, 34 pin Floppy drive connector, SATA connectors and the 50 or 68 pin SCSI otherwise known as Scuzzy. Today’s computers uses PCI, PCIX, PCIe(express) and AGP expansion slots to connect peripheral devices and system of buses.PCI is fast, PCIX is faster, PCIe is the newest, fastest...

...Short Answer Computer Structure and Logic May 11th, 2016 Professor Martin Rachel Baldwin The major concepts of the motherboard include; peripherals, Interface cards, daughter cards: sound cards, video cards, network cards, hard drives, TV tuner cards, cards providing extra USB or FireWire slots and a variety of other components. A peripheral is a device that is used to put information into get information out of the country. The Daughter cards or daughterboard contains plug sockets connectors for other boards to attached to. Daughterboards only have internal connections. Next is the sound cards. The sound cards is an internal computer expansion card. It facilitates economical input of auto signals to and from a computer found under control of a computer programs. Video cards is a type of expansion card this also generates a feed of output images to the display. They are frequently advertised as dedicated graphics cards. Which is a big difference between the integrated graphics. Sometimes video cards are called graphic add- in- boards. Network cards is a computer hardware component that connects a computer to a computer network. (Wi-Fi connection) The hard drives is a data storage device used to store and retrieving digital information using one or more rigid(hard) rapidly rotating disks platters coated with megnetic material. TV tuner card is a kind of television that allows TV signals to be retrieved by a computer. Most TV tuners function as video capture cards which allows...

...analyze, and evaluate the significant influences that work for or against its strategic objectives (Sultz & Young, 2009). Strategically planning will help aid Sandwich Blitz with the decision of expanding and locating new locations. It allows for all management persons to get involved in the process. Although I believe that the expansions should be on small scale because this allows them time for growth if the new expansion takes off. The biggest STRENGTH of Sandwich Blitz is that they have the resources to open two additional locations if good locations can be found. Another strength would be, that they have the staff to move to these new locations. This also allows for low level management to get involved in the marketing of the new expansions. A major WEAKNESS of Sandwich Blitz is that due to the recent economic downturn, the larger park offices have been affected and this could affect business because people are probably not shopping in these areas too much. They would probably have to come up with cheaper menus and do specials to attract business which could be costly. The OPPORTUNITY for Sandwich Blitz would be that the expansion allows for more business especially if it is moved to another city. The new city may not have top competitors or mimics of Sandwich Blitz and this allows to them to enter another market. Another opportunity is that it can bring about new business and more customers for the franchise. It also gives them the opportunity to create new...

...add-on cards. Most desktop computers have a form factor that is some variant of ATX. A case designed for an ATX motherboard and power supply may take on several external forms, such as a vertical tower (designed to sit on the floor, height > width) or a flat desktop (height < width). Computer cases usually include: sheet metal enclosures for a power supply unit and drive bays; a rear panel that can accommodate peripheral connectors protruding from the motherboard and expansion slots; a power button, a reset button, and LEDs to indicate power status as well as hard drive and network activity. Major component locations * The motherboard is usually screwed to the case along its largest face, which could be the bottom or the side of the case depending on the form factor and orientation. * Form factors such as ATX provide a back panel with cut-out holes to expose I/O ports provided by integrated peripherals, as well as expansion slots which may optionally expose additional ports provided by expansion cards. * The power supply unit is often housed at the top rear of the case; it is usually attached with four screws...

...The Effect of Compiler Optimizations on Pentium 4 Power Consumption John S. Seng Dean M. Tullsen Dept. of Computer Science and Engineering University of California, San Diego La Jolla, CA 92093-0114 jseng,tullsen @cs.ucsd.edu Abstract This paper examines the effect of compiler optimizations on the energy usage and power consumption of the Intel Pentium 4 processor. We measure the effects of different levels of general optimization and specific optimization. We classify general optimizations as those compiler flags which enable a set of compiler optimizations. Specific optimizations are those which can be enabled and disabled individually. The three specific optimizations we study are loop unrolling, loop vectorization, and function inlining. The binaries used in this study are generated using the Intel C++ compiler, which allows fine-grained control over each of these specific optimizations. ¡ 1. Introduction The power consumption of general purpose microprocessors has reached a point where the problem has to be addressed at various levels of system design. Many circuit, architecture, and software algorithm techniques exist to reduce power, but one often overlooked area is the effect of the program code on power consumption. Some research has been done studying the effect of compiler optimizations on power consumption [8, 9]; this work has been generally limited to using architecture-level power models for power estimation. In this work we examine the effect of the compiler...

...components of a computer mother board are the processor, memory, chipset, expansion slots, and IO bank. The Processor is the brain of the computer. The processor is the chip where all of the computing is completed. The processor is usually removable and inserted into a socket. The processor can be attached directly to the mother board. The processor is normally protected by a heat sink which assists in removing heat and protects the processor from burning out. The memory is where the computers stores all of the information. The computer memory is usually installed on a board called a SIMMs. SIMMs stands for Single Inline Memory Module. Single Inline Memory Modules come in different sizes. These sizes include 2G, 4G, 8G, and up. You can have one memory installed on a board or you can have multiple memory installed. The amount of memory that is allowed on a board depends on various factors. These factors include the processor, the board itself, and the BIOS. The memory is usually removable. The chipset is a term that refers to a chip or a set of chips. The Chipset is a link between the processor and the outside world. The chipset controls the USB ports, keyboard, mouse, and hard drives. The Chipset generates the sound that the computer makes. The Chipset creates the images that you see in the screen. The Chipset is usually attached directly to the mother board and usually has heat sinks attached to them. The Expansion Slots are connectors that allow you to attach cards on the computer...

...Exploring the Motherboard and Busses Short Answer 7/29/15 Mr. Lanning Gene Jackson II The components of a motherboard are the cpu, bios, mass storage interfaces, serial and parallel ports, expansion slot and controllers for peripherals. The CPU controls the operations of the hardware and software. BIOS (basic input/output system) is software that controls basic computer hardware functions. Mass storage are things such as the RAM which temporarily stores files while the computer is functioning. The serial and parallel ports allow SETA and other connections to be hooked up to the motherboard. Expansion slots are for video cards and other such hardware that will increase your motherboards value and the controllers are for things such as keyboards or mouses. The improvement upon upgrading the motherboard would be limited because the motherboard is what holds the most important pieces of the computer together and doesn’t have much more significance other than that. It is more of a highway between all of the other functioning pieces. The buses communicate with the CPU and other devices in the computer. One set of buses connects the CPU to RAM and external caches. Another set of buses connects a large number of different I/O devices. These functions cannot be performed on a single bus because there are too many different functions to be performed. It would be a mess and confusing and could result in a overload on the bus components. 32 bit busses may still be necessary even...
