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.
Answer the following questions:
• What are the major components of the motherboard? Provide a brief description of each component.
• Upgrading only the motherboard will give some performance improvement to a computer system. Why would the improvement be limited?
• What is the need for all the different busses found on a motherboard? Why can these busses not be replaced with a single bus?
• With 64-bit busses available, why should 32-bit busses be provided as well?
The motherboard of a computer is also known as the System Board. The circuit board is the platform on which all the hardware of the computer is connected. It is said to be the most important part of the computer. The expansion cards, and slots, BIOS chip, CMOS battery, jumpers and DIP switches, heat sink, PCI, Power connector, on board disk drive connectors, memory slots, keyboard connectors, Peripheral ports and connectors are all the things that one may find on the motherboard. The expansion cards are a typical part of nonintegrated system board. An example of this is a graphic card. Memory slots are one of the most important part of the system board. The number of memory chips on a motherboard depends on the type of CPU and its capacity. The slots are usually white and black and close in proximity to one another. The BIOS chip is also a very important part of the system board. It directs the CPU to other parts of the computer. BIOS and its manufacturers name are usually written on the chip. The CMOS battery or (complementary Metal Oxide Semiconductor) is a small battery on the system…...

...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......

...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......

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.

...Short answer 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......

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.

...Exploring the Motherboard and Busses Short Answer Assignment Instructor Haroon Margaret Harm 2/18/2016 1. What are the major components of the motherboard? CPU-Central Processing Unit- also known as the microprocessor or processor. It is the “brain” of the computer. It is responsible for fetching, decoding, and executing program instructions and mathematical and logical calculations. RAM-Random Access Memory- is volatile memory, meaning that it loses its contents once the power is turned off. Basically, it is the work place of the computer where active programs and data are loaded so that any time the processor requests them, it doesn’t have to fetch them from the hard disk which will take longer access time. BIOS-Basic Input Output System- consists of low-level software that controls the system hardware and acts as an interface between the operating system and the hardware. BIOS is all the drivers- it is the link between hardware and software in a system. CMOS-Complementary Metal Oxide Semiconductor- a small separate block of memory made from CMOS RAM chips, supported by a CMOS battery even when the power is off. It is used to store basic information about the PC’s configuration, for example, floppy disk and hard disk drive types, CPU, RAM size, date and time, serial port information, plug and play information, and power saving settings. Cache memory- a small block of high speed memory that enhances PC performance by pre-loading information from the main......

...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...

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 Short Answer 3.1 07/20/2015 Michael Huffman Brandon Rodgers When looking at a motherboard, it can be very confusing to say the least. Some of the things you may see on one include; * CPU socket- This socket is where you would place your selected CPU * PCI slots- These slots are the places where you would add expansion cards i.e. Sound, video or network cards * DIMM slots- this is where your selected RAM is placed. (preferably in pairs) * CMOS battery. This battery is in charge keeping all the little thigs going, keeping the system clock etc. Up to date. This goes bad, you will have problems. * Various jumper ports and powering pin ports. When looking to upgrade just the motherboard. You will have to take into account the possibility that your current CPU and other components listed above may not be compatible. Making sure it will fit into the chassis is very important due to the need for a ground. The minimum improvement may just be that. Better heat dissipation is a major improvement. But as before the throttle back with a slower out of date CPU would be a major non improvement. The many different busses are in place for the many different components that are out there for use. The need is simple, not every component is built the same so there couldn’t be a single buss. In a perfect world possibly. The data management or Bandwidth is controlled by these......
