Exploring the Motherboard and Busses

What are the major components of the motherboard? Provide a brief description of each component.
CPU: The central processing unit is basically the ‘brain’ of the computer. It is where all the computing takes place. Wiki states “Electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions (Central processing unit)”
BIOS Chip: Encrypted with code, it takes the computer through a boot up process until the OS is ready to take over. Upgrading only the motherboard will give some performance improvement to a computer system. Why would the improvement be limited? Upgrading the motherboard would give it a performance improvement but yes improvement would be limited. This is simply because there is much more than just the motherboard that makes up a computer. There is RAM, there is a hard drive. Also when upgrading the motherboard you have to make sure to upgrade the CPU and memory. What is the need for all the different busses found on a motherboard? Why can these busses not be replaced with a single bus? To understand why we need different busses, you need to understand what a bus is. A bus gives a path to a device so it can sent data to the CPU and other devices. There are more than one device that needs to send it information there for we can not just have one bus. We have to have multiple buses for multiple components. To give a more precise definition, “each device will have an access point to the bus using a particular kind of interface. The word interface refers not only to the physical port the devices plug into, but to the electrical operating parameters and the communication format as well. Typically, each bus has a uniquely shaped interface to

Busse Place

...In the Harvard Business School case, “Busse Place,” Collins Properties realized their investment property, Busse Place, was not meeting their revenue projections and needed to determine an appropriate course of action. Bill Fairchild, the Vice President of Asset Management at Collins Properties, would have to decide whether to continue to fund the project, attempt to restructure their CMBS loan, or default on the project altogether. Prior to making this decision his leasing agent, Marisa Sanchez, would have to assess the likelihood of being able to attain new tenants, and determine what rates and terms to offer each, then Fairchild could create a new pro forma analysis, to use as reference when making his ultimate decision as to which course of action to take. Sanchez had recently provided proposals to three prospective tenants. The first, Northwestern Trust Company, was the largest prospect. Securing Northwestern Trust Company would be crucial to the overall success of Busse Place, as they would occupy approximately 16% of the total rentable space, increasing the occupancy rate to 54%. Based on Sanchez’s assumptions regarding the current market conditions, she believed the average net present value of rent for the two newest tenants at Busse Place, was $2.03 higher than those from 1500 Higgens Rd. and $6.07 higher than those from Two Schuamberg Place. Additionally, Sanchez received information that her initial offer to Northwestern Trust Company was $1 to $2...

...EXPLORING THE MOTHERBOARD AND BUSSES/ MODULE-3/TANWEER HAROON/ROLAND DAVIS/6-22-2016 The major components of the computers motherboard are The Processor, The memory, The Expansion Slots and the IO Bank. The Processor is the brain of the computer, it’s where all the computing is done, it’s a small chip that resides in computers and its job is to input and provide output. The processor handles all the basic system instructions, such as the processing mouse, the keyboard, input and the running applications. The memory is the internal storage areas in the computers storage. Its device is used to store information for the immediate use in the computer. Computer memory operates at a high speed. The Chipset is a set of electronic in an integrated circuit that manages the data between the processor, the memory and the peripherals. The chipset is found on the computers motherboard where it’s designed to work with a specific family of microprocessors and because of it’s controlled communications between the processors and external devices. The chipset plays a crucial role in determining system performance. The Expansion slot is a socket on the motherboard that is used to insert an expansion card or circuit board that provides an additional feature to a computers such as advance graphics, sound, Ethernet, memory and video. Expansion packs are also referred to as a bus slot. Expansion slots for pc’s come in different sizes and that’s half and full size. The IO is the input and output...

...Unit 4 Writing Assignment – Motherboards and Busses 1. The improvement of the motherboard will be limited because of compatibility issue with other hardware. Other devices run at a different speed and have different processing requirement, for example the memory and hard drive; without upgrading these components too will limit the performance of the motherboard. 2. There is a need for the different busses to be on the motherboard for free flow of information processing by way of obtaining different sets of instructions. 3. A 64-bit OS has a higher functionality than a 32-bit, a 32-bit will be needed because of the backward compatibilities of the 64-bit. 4. The following requirements must and can be considered when building a PC: * DO NOT plug anything in unless the computer is fully turned off.  * DO NOT install anything unless you are grounded through a wrist strap * DO NOT over-tighten or strip any screws.  * Never force anything. If it does not fit or plug in then figure out why. * Wear surgical gloves while putting the PC together Next  Choose your components. You will need a:  Motherboard  CPU Memory  Hard drive  CPU Cooler  Graphics card.  Power Supply Unit.  The motherboard should be compatible with any CPU you choose. I recommend gigabyte motherboards.  Choose the CPU first, and then pick a motherboard it will work with.  After you got that selected you will need to find memory.

Motherboards and Busses

...Joe Bible computer structure and logic motherboards and busses week 4 Tuesday class 10-8-2013 unit 4 The title of the videos I watched were: An overview of motherboard types and also the video motherboard expansion slots and bus speeds. The two videos covered expansion slots the setup of a motherboard as well as bus speeds. The types of typical motherboards are standard atx and micro atx there is also mini itx nano itx and pico itx these last three are smaller to fit in smaller computers. They are mainly the same having similar power as well as similar mounting but have less expansion slots then the atx versions. Atx stands for Advanced technology extended and was standerized by intel in 1995 and can added and removed as needed. Atx boards are powered by a 20 or 24 pin connector. There are over 40 different types of motherboards but these are the most common now days. Expansion gets its on clock one MHz is equal to one million cycles per second one GHz is 1000 MHz. clock speed does not necessarily equal transfer rate. Throughput varies by bus verions 133 MB/s is 32 bit at 33MHz 266 MB/s is 32 bit at 66MHz or 64 bit at 33MHz and 533 MB/s is 64 bit at 66 MHz.

Busse Case

...In the case of F.J. Busse vs. Department of General Services, Busse was contracted by the General State Authority to build a fountain in Point State Park. When the area was nearly excavated, Hurricane Agnes deposited 6 inches of dirt onto the site. Busse submitted a change order for $85,000, but the General State Authority only granted Busse an extension of time. The GSA said that any funds recovered from federal reimbursement would be paid to Busse, but no funds were ever recovered. The court ruled that Busse was responsible for the cost of the dirt removal from the job site under the terms of the contract. The court said that even though neither party was responsible for the loss, the party who agreed to take the loss must be responsible for it. In this case, the court decided that Busse agreed to take this loss. In the contract, the provisions are quite vague with Busse agreeing to take the loss from “any other hazard”. The court used this to say that damage from a hurricane could be included under this. The court also ruled that the damage to the job site did not make fulfilling the terms of the contract impossible, but just more expensive. In this case, it does not seem that the court deemed the cost of the cleanup to be impractical, or much more costly than anticipated. I do not agree with the findings of this court. While the contract did leave Busse liable for a multitude of possible damages, I do not believe than a severe act of God like a hurricane should be included...

...Farhana Haque NT1110 4/21/15 Exploring the Motherboard and Busses The motherboard represents the logical foundation of the computer. Everything that makes a computer must be attached to the motherboard. The major components of a motherboard include I/O port cluster, memory slots and expansion slots, and mass storage interfaces. All of these components work together to make the computer run as efficiently as possible. The integrated I/O port cluster can be located in as many as three different places. All motherboards feature a rear port cluster, and many motherboards also have additional ports on the top of the motherboard that are routed to header cables accessible from the front and rear of the system. The most recent motherboard include serial (COM), parallel (LPT), PS/2 mouse, PS/2 keyboard, USB 2.0, Ethernet, audio, FireWire, VGA, and HDMI ports. Integrated ports provide efficiency when it comes to performance and installment, but may provide problems when it comes to repair. Modern motherboards include two or more memory slots. Memory slots vary in design according to the type of memory the system supports. Each memory slot includes locking levers that secure memory in place. Motherboards use expansion slots to provide support for additional I/O devices and high-speed video/graphics cards. The most common expansion slots on recent systems include PCI, AGP, and PCIe. Some systems also feature AMR or CNR slots for specific purposes. Mass storage interfaces include...

Exploring the Motherboard and Busses

...Exploring The Motherboard and Busses Gregory Henry 1136-E2-NT1110 Henderson, David 1. What are the major components of the motherboard? Provide a brief description of each component. The motherboard has a variety of components that make it up. The brains, and most important part is the CPU, or central processing unit. It is where all the calculations of the computer take place. The CPU is generally just one chip, called a microprocessor, which connects via small metallic pins directly to the motherboard. Each CPU contains two components, an ALU, which carries out all the arithmetic and logical operations of the computer, and the CU, which actually gives the computer instructions on how to do tasks and executes them. In terms of computer memory RAM is where data is kept from the operating system and applications so that they can quickly be used by the processor. However, once you turn your computer off all the data is lost. Think of it as short term memory. Long-term memory would be your Hard Drive. The hard drive can come in two forms. An HDD, which uses a rapidly spinning disk coated in magnetic material to store information. It has non-volatile memory, meaning it retains information when powered off. The other kind of hard drive is a Solid State Drive, or SSD. Solid State has significantly higher rates of transfer, better reliability, and lower latency access times. But that premium comes at a price, as SSDs are generally more expensive per bit of storage...

...Jonathan Nieh Law 434 Business Skills for Real Estate Lawyers Professor Habibi 3/2/2015 Case Study: South Park IV 1. Considering the recent upward trend of employment, the downward trend of vacancies in the area for industrial properties, the relatively good terms being offered for financing, and the recent upward trend of oil prices, I believe that this would be a good property for Laflin to acquire. 2. Laflin’s assumptions: vacancy rate of 5%, management fee of 4%, he needs only $15,000 for structural reserves, there will be no closing costs, and most importantly that either the current tenants will extend their leases for the same rates that they are currently being charged or that he will be able to re-rent the property for the current rate. His last assumption is incorrect, however, because the tenants indicated to him that they would only extend their leases if Laflin actually reduced their rents to $2 per square foot which would drop gross potential rents to $160,000. His vacancy rate seems very low as well considering the fact the average vacancy rate for Houston in 1989 was 13% and was much higher the previous few years. The management fee of 4% appears accurate as management fees typically range from 3-5%. However, his assumption that he would need only $15,000 for structural reserves seems rather low. Since current monthly rents are about $16,666, his structural reserves wouldn’t even be enough for one month’s rent. If it were me, I would have at...

...Exploring the Motherboard and Busses Major components of the motherboard are the CPU, I/O ports, memory slots, expansion slots, mass storage ports, and busses. The CPU is the brain of the computer. It processes all of the computers functions. I/O ports connect input and output devices to the computer. Memory slots allow RAM to be inserted and to add additional memory. Expansion slots allow additional boards to be connected like, video, sound, or network cards. Mass storage ports connect storage devices like hard drives, CD-ROM, AND DVD-ROM. Busses are tiny electrical paths to connect each component of the computer together. If you upgrade the motherboard to give it performance improvements, the improvements are going to be limited because the motherboard doesn’t really improve the overall power of the system. You have to upgrade more than just the motherboard to improve speed and other things. The need for all the different busses on a motherboard is that each on has its own data width, cycle rate, and device management. The data width and cycle rate is used to determine bandwidth or how much data can be transmitted at one time. The device management indicates the maximum number of supported devices and the difficulty of configuring them. These busses can’t be replaced by a single bus because there is not bus fast enough to handle all these jobs at the same time and still be sufficient. With 64-bit busses available, 32-bit busses are still provided because many...

What is the need for all the different busses found on a motherboard? Why can these busses not be replaced with a single bus? You need different busses on your motherboard because there is simply too much exchange or flow of data for just one bus therefore you assign them they’re own devices or jobs to keep the performance of the computer from slowing down. With 64-bit busses available, why should 32-bit busses be provided as well?

Basically the processor socket is the input socket for the processor, the ddr2 memory slots are for the ram (random access memory), and the heat sink acts as a radiator for the processor on the north bridge, the south bridge chip is the side of the motherboard that manages Legacy, Bios, IDE, ISA, USB, and PCI. The PCI slot is for adapters for optional video input or modems, the CMOS battery remembers the BIOS of the motherboard even when pc is turned off or unplugged, unless it is removed and the board is discharged while everything is unplugged and removed and the power button is held down for a certain amount of time depending on the manufacturer of the product, the port cluster is the I/O(input output) port holes of the motherboard, The SATA host adapter is for high speed connection usually on laptop HDDS but are now on desktops as well, the ATX12 power connector is a cluster of resistors and components that transfer the power prom the external source, and the mounting holes are the holes to mount the motherboard to the tower. Just upgrading the motherboard isn’t going to give you much more performance increases, other hardware is required such as more ram, a faster processor, a more efficient heat sink and fan and many other factors that go into more performance.
