...Exploring the Motherboard and Buses NT1110 What are the major components of the motherboard? Provide a brief description of each component. The major components to the motherboard are the power supply, memory slots, expansion board slots, mass storage, I/O ports, and the CPU. The power supply is used to supply all of the computer with the appropriate power. The memory slots are used for inserting Random Access Memory cards into, to allow memory to be temporarily stored only when power is applied. If power is lost, the memory will be lost. Expansion board slot are used to support adapter cards such as PCI express, AGP, or PCI cards. These slots allow for many different additions onto the motherboard, graphics cards, addition USB ports, LAN cards, etc. Mass storage are simply nothing more than the hard drives and optical drives. The I/O ports are ports that come integrated to the motherboard, which means it cannot be removed. But the ports can be anything from mouse/keyboard hook ups, to integrated Ethernet ports. Finally the Central Processor Unit, CPU, the brain of the computer. This is where the calculations are all done and how fast they can be done is determined by the power of the CPU. Upgrading only the motherboard will give some performance improvement to a computer system. Why would the improvement be limited? The upgrade would be limited because the motherboard is merely nothing more than an information high way but you can direct the motherboard towards a path that...

...Current Marketing Situation The primary target market for UScoot is college students enrolled at Ole Miss. Parking on campus is getting worse and worse, and the situation is opening up a very large market for alternate transportation. Ole Miss is closing in on 20,000 students, and the university plans to continually increase enrollment, which will continually increase the size of UScoot’s target market. A secondary market for Uscoot will be campus employees. There are more than 2,500 Ole Miss employees, many of whom are searching for alternate transportation just as the students are, and as student enrollment rises, Ole Miss will have to employ even more people, and this will increase the size of the secondary market as well. Obviously, UScoot will available to anyone who wants to use the service, but the biggest portion of the business will definitely be centered around Ole Miss students. There are 38,000 residents in the city of Oxford, and these 38,000 residents represent the total market for UScoot. The size of the target market is between 15,000 and 20,000, which represents all students enrolled at the university. UScoot will only need to capture about 1% of this market to be profitable. It is not at all unreasonable to believe that UScoot can achieve this number of customers very quickly, and the potential for growth past that number is excellent as well. Enrollment will continue to rise, and the popularity of UScoot is bound to increase as more and more people learn...

For example, the device may allow seven devices to connect to one serial port. Hardware Expander Types: * Ethernet Port Expander Hardware * FireWire Port Expander Hardware * DB-25 Port Expander Hardware * Serial Port Expander Hardware * USB Port Expander Hardware * VGA Port Expander Hardware * DVI Port Expander Hardware * SCSI Port Expander Hardware * Audio Port Expander Hardware * Video Port Expander Hardware * Microphone Port Expander Hardware * RS-422 Port Expander Hardware * Modbus Serial Port Hardware * SATA Port Expander Hardware * SAS Port Expander Hardware * SSD Port Expander Hardware Port expanders are generic devices that can be used with any computer as long as the computer has the port for which you are trying to use and expander for. Now pretty much every computer from PC to MAC has all the same ports on them. It used to be that MAC was the only one using Firewire, but then it became available on the PCs. However, even since it became available on PCs, it has now been mostly phased out. Well, depending on what you are using it for there are different kinds of advantages and disadvantages. If you are using it on a desktop or home computer one of the advantages is the ability to allow more devices of a particular port type to be utilized at the same time. One disadvantage...

...Coming back home after a long and exhausting day at school, the one thing I desire is peace and quiet. I lay there, still in my bed. The only movement is in my wrists from the swift flicking of pages of the book ‘Twenties Girl’ written by Sophie Kinsella. The amity is so divine, so serene, so heavenly and tranquil. If anything could be as close to heaven, this would be it…. BRING! BRING! BRING! BRING! Suddenly the dream I considered reality, was viciously awoken by the sound of the ear-splitting entry phone. OH GOD! What I was dreading the most has finally arrived at my doorstep! I know you are thinking “Who’s at the door? A crazy old women? A mental asylum patient? A serial killer?!” But no. None of those. Unfortunately, it’s worse! My infuriating little cousin. I guess dear listeners, that by now you’ve figured what my topic is. Yes. Annoying children. You may think that I am a stone hearted, droning, inconsiderate teenager rambling on about annoying children. But the fact of the matter is that if there is one thing that I absolutely cannot tolerate, it is my peace being destructed by these aggravating, bothersome, petty children, and especially then, when there is a multitude of them. It’s been about three weeks now, since these rebellious guests attacked the harmony from within my peaceful home, which has thankfully, now been restored after the departure of these insolent beings. I was in my room, trying to concentrate on reading my book in peace and it felt impossible...

...“You can resign and go to SBS,” the drivers were told by Vincent Wijeysingha on Sunday, 2 December 2012 at 21:52 · The government has acted in our name as is its duty. It purged an industrial action and returned the nation to business as usual. The bus drivers from SMRT recklessly involved themselves in an illegal strike after refusing to bring their grievances to management or their trade union or seek the assistance of the Manpower Ministry. Twenty-nine have been deported, one hundred and fifty more issued a police warning and the five ringleaders will be tried. Industrial harmony has been restored, the tripartite relationship upheld, and public disorder averted. As fortunate citizens of this prosperous and stable nation, we can heave a sigh of relief. Those refractory foreigners got what they deserved. How dare they come to our land - which our government built from a fishing village - and demand such indulgences as suitable accommodation and an equal wage. Nobody promised them any of that: if they aren’t happy here they can fuck off back home. There are too many damn foreigners here as it is. The come here to steal our jobs, marry our women, clog the trains, explode housing prices, beat up taxi drivers, and drive Ferraris too fast. They dance outside Wisma Atria and jam the staircases at Lucky Plaza. Oh, and they smell. And talk too loudly. In strange accents. In short, they are audacious and unpleasant. Oh, and they smell. Did I mention that? They do. And they...

...Explain what a System Bus is and why it is needed ? By: Katina Howard Prof: CLIFTON-HOWELL Date: Jan.31, 2013 INTRO TO TECHNOLOGY A system bus is a single computer bus that connects the major components of a computer system. The technique was developed to reduce costs and improve modularity. It combines the functions of a data bus to carry information, an address bus to determine where it should be sent, and a control bus to determine its operation. Although popular in the 1970s and 1980s, modern computers use a variety of separate buses adapted to more specific needs. The System Bus provides even more modularity with reduced cost, memory and I/O buses (and the required control and power buses) were sometimes combined into a single unified system bus. The modularity and cost became important as computers became small enough to fit in a single cabinet (and customers expected similar price reductions). Digital Equipment Corporation (DEC) further reduced cost for mass-produced minicomputers, and memory-mapped I/O into the memory bus, so that the devices appeared to be memory locations. This was implemented in the Unibus of the PDP-11 around 1969, eliminating the need for a separate I/O Even computers such as the PDP-8 without memory-mapped I/O were soon implemented with a system bus, which allowed modules to be plugged into any slot. Some authors called this a new streamlined "model" of computer architecture. Many early microcomputers (with a CPU generally on a single integrated...
