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. These videos taught me a lot as I did not know any of this info. The videos taught me that although the cpu does most of the processing the motherboard handls thing such as memory espansion slots for grap hics video and so forth. What I have found confusing is why do they make different motherboards that use different voltage requirements. Why not just make a universal voltage requirement they never really explain this also they were a little vague on buses I know it has to do with the speed of your expansion slots but not very much else even after watching the video. You could use all this information if you were making your own computer from scratch…...

Motherboard and Busses

...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.

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.

...Video 1.04 Motherboards The motherboard determines what CPU you must buy and vice versa. There are 3 form factors of primary interest today, the ATX, the BTX, and the NLX. The ATX replace the older AT models. By making it smaller it made it easy to work on it. The ATX also has a soft power button on the front and when pressed while operating the computer it will not completely cut off until it does the OS shutdown process. There is also a power switch on the back that kills the power immediately. If you have the Wake on LAN configured to the CMOS, keyboard activity, or network activity, while the system is in standby it will repower the system. Buses are a communication system that transfers data between components inside a computer. • ATX Form Factor o Replaced older AT form factors o Smaller o Better Organized o Easier to work on o Support for wide variety of I/O device o Soft Power Button  Soft Power Button  Does not immediately cut power  Allows normal OS shutdown process o Wake On LAN  Configured in CMOS  Keyboard activity  Network activity • BTX Form Factor o 20 or 24-pin P1 power connection o Better air flow for better cooling  Intake vent at front  Exhaust vent in back  CPU heat sink fins and memory modules installed parallel to air flow • NLX Form Factor o Supports riser cards  Fit into expansion slots  Provide connectors for additional expansion cards  Also known as daughter boards • Communication Buses o Buses  Appear as......

...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...

...James Mason 4/13/15 NT1110 In the article about motherboards, there was a wide variety of topics covered. There was a brief history of the motherboard, as well as history on most all of pieces of hardware that is used on a motherboard. Also covered were some of the latest pieces of hardware, including some different terminology which relates specifically to them, differentiating them from older versions just by title. Lastly, and possibly most importantly, along with each topic was an explanation of what it does and how specifically it functions in regards to the other hardware of a motherboard. Some important topics covered were: • The importance of choosing a motherboard with an optimally matched chipset based on a desired CPU. • The importance of RAM and how it ultimately affects the overall speed of a CPU and chipset. • The importance choosing a proper video card or sound card depending on the use of the computer. • Bus speed is another important factor in computer speed, in particular, Front Side Bus, or FSB. Some important terms covered were: • Central Processing Units, or CPU’s, which is like the brain with the chipset being like the central nervous system, sending and receiving the information. • Peripheral Connections, or PCI, as well as the newer express version, PCIe, for things such as video or network adapters • Accelerated Graphics Port, or AGP, which is used solely for video cards. • Integrated Drive Electronics, or IDE, is how hard drives......

The purpose of this statement was to help black and white people come together and be peaceful all around the world. Plus he mention the dream he had one night when we as blacks and whites and different race would be around each other and live life beautifully but the racist stuff would have to stop. He gave a very powerful speech and it means a lot still to this day. 2. Give the context of the speech. Why was it given? What historical events led to the speech? The context of the speech was made in Washington D.C. and it was brought upon blacks fighting for their rights in America. It was given so every race could be aware of the horrible ways African American people were being treated. The historic events that led to the speech was in 1955 blacks where getting treated like they were not even human. Also they couldn’t walk into any bathroom; they had to go to the restrooms that said colored. They couldn’t vote so they had to fight for those rights. And some whites just didn’t agree with being in the same area or room the African Americans was in. 3. How do rhetorical patterns help the author support his or her argument? It helps real well.

Exploring Motherboard and Busses

...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......

Motherboard

...Motherboard, Short answer, 5/14/15, Ikhlas Abdulsaid, Daniel Witzel The motherboard represents the logical foundation of the computer. In other words, everything that makes a computer a computer must be attached to the motherboard. From the CPU to storage devices, from RAM to printer ports, the motherboard provides the connections that help them work together. The motherboard is essential to computer operation in large part because of the two major buses it contains: the system bus and the I/O bus. Together, these buses carry all the information between the different parts of the computer. The location and orientation of these buses varies depending on the type of form factor used. The form factor is the design of the motherboard, which the case and power supply must comply with. Motherboards can come with integrated I/O ports; these are usually found as a rear port cluster. The motherboard also has memory slots, which enable a user to add sticks of RAM, thus increasing the computer’s total resources. Of course, the motherboard also has expansion slots most commonly used by audio and video cards, although the slots can be uti- lized by many other types of cards as well. You also find mass storage ports for hard drives, CD-ROMs, and DVD-ROMs on the motherboard. Upgrading only the motherboard will improve the performance of the computer system limitedly because if you motherboard is pumping info at 100mph and your CPU and busses only max out at 50 mph, you will need to......

Exploring the Motherboard

...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......

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......
