...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 copper...

...Motherboard Answer the following questions 5 April 2015 Tanweer Haroon DeJong May The major components of the motherboard are as follows: memory and their slots which is the computer’s memory (RAM) and is one of the most important parts of the system board. The number of chips depends on the type of computer and its capacity. Expansion cards are a typical component of non-integrated system boards a graphic card is a perfect example, but this can be integrated into the motherboard. CPU and slots is the central processing unit and it’s a highly prolific part of the computer and is located on the right of a motherboard and can be identified as a result of the heat sink or cooling fan directly on it. BIOS chip directs the CPU with respect to how it relates with other parts of the computer. Its basic input and output system chip or integrated circuit is fixed on the board and is easily identifiable. CMOS battery, the complementary metal oxide semiconductor is a small battery on the system board that powers the CMOS memory. Power supply and connectors is the electrical unit of the system and if it’s bad the system will not work. Keyboard connector are located on the motherboard and there are two main types. The AT has a round connecting interface into the motherboard and the PS/2 connector is rectangular in shape and smaller. Modern motherboards come with both. Mouse connector its connecting port is located on the motherboard and its interface is usually round. Floppy...

...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 upgrade...

...Instructions on replacing motherboard If you are replacing the motherboard with the same model, you should not have to reload the chipset or have to re-install the operating system. This is not always the case but normally it is. If you have access to your personal data, you may want to back it up before replacing the motherboard just to be safe. If you are replacing the motherboard with a different model, then the chances are good that you will have to reload windows. You might be able to install just the chipset and be OK but if that doesn't work, then a re-install is needed. Below is instructions on replacing a motherboard. This is general instructions. Due to the numerous variations of computers, I am not able to go into detail but can give general instructions. For more specific instructions, consult the manufacturer of your computer. NOTE: Most if all cables and connections are easy to determine where they go. Most cables will only plug into one location only so there is no confusion where they plug in at. Also most connections are keyed so they will only go in one direction so you can't accidentally reverse them. However there are a few motherboards that uses cables that you may not be able to determine which one goes where. Before removing cables, check to see if there is more than one location that cable can plug into. You can also do the following to make sure you don't plug it in the wrong place. 1. Draw a diagram of the motherboard. 2. On the diagram...

...computer you must decide between the motherboard or cpu first. Not all motherboards will fit in all cases. There are a few motherboard form fators ATX, BTX, and NTX. The ATX motherboard feature standard locations for the keyboard, mouse, I/O, and video connectors. Some design improvements of the ATX are a single 20-pin connector for the power supply. The BTX was developed to take advantage of the serial ATA, USB 2.0, and PCI express. Some changes for the BTX are better component placement for the back panel I/O controllers and its smaller than the ATX form Factor. The NLX is used on low end computers and supports riser cards. Also provides more flecibilty for system level designs. * Wake on LAN – keyboard or network activity * Power switch – Immediately kills all power * Communication Buses Expansion Slots * Buses – copper tracing, connect various components, allow delivery of power and date * System Bus – Largest bus, Fastest Bus, Connects motherboard to CPU * Connectors – P1 power, 40-pin IDE, 34-pin floppy drive, SATA, 50 or 68 Pin SCSI * Expansion Slots * 8-bit ISA – Used in early computers, Two lane dirt road * 16-bit ISA – Next Generation * MCA * EISA * Vesa Local Bus * PCI – Fast (White and Longer) * PCIx – Faster * PCIe(express) – Fastest, expected to replace AGP * AGP- High Speed alternative to PCI, Used for video (Brown and shorter) Motherboard Form Factor * ATX – Smaller...

...Motherboard Replacement Process IT280 January 15, 2012 In the following paragraphs, you will learn how to remove and replace a motherboard. It can be a simple process if all the steps are followed completely. These steps will allow a computer techie to “do it yourself” since these are simple and easy steps. The first step of replacing a motherboard is to remove the old motherboard. You will then need to remove all connectors to the rest of the components for easy access of removing the old motherboard and not damaging the new one. Next, unplug the power supply and the data cable from the hard drives. Remove the PCI adapters and the video card. All of the adapters that mount in motherboard slots are secured to the back rail of the case with a single screw. You may as well take all the screws out at the same time and put them aside in a glass jar or any other small container to keep them from getting lost. Then remove the data cables from the old motherboard. Lastly, remove the small screws that are keeping the motherboard attached to the case. To easily install the new motherboard, you will need to make sure the I/O cover matches the new motherboard. If not, use the new one that came with the motherboard and punch out the correct ports and then install it in the case. Make sure that the motherboard and the holes match up with the case before screwing the cover into place. Then install the motherboard at an angle with the I/O core first making sure everything will line...

...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...

...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.

...What is a Motherboard? The Motherboard is the main circuit board inside the PC. It holds the CPU and memory, provides expansion slots for peripherals, and, whether directly or indirectly, connects to every part of the PC. The essential motherboard make-up includes the chipset (known as the “glue logic”), some code in ROM and the various wired interconnections between the components know as buses. The chipset is fundamental, and controls how the motherboard interacts with everything else in the system. A good chipset can be more important than the power of CPU or the amount of RAM. The ROM code includes the BIOS, which has user-changeable options for how the motherboard operates with integral and connected devices. The buses are the electrical wires that connect everything together. Motherboard designs use many different buses to link their various components. For instance, wide, high-speed buses are difficult and expensive to produce. The signals travel at such a rate that even distances of just a few centimetres cause timing problems, while the metal tracks on the circuit board act as miniature radio antennae, transmitting electromagnetic noise that introduces interference with signals elsewhere in the system. For these reasons, design engineers try to keep the fastest buses confined to the smallest area of the motherboard and use slower, more robust buses for other parts. Types of Slots on a Motherboard Motherboards are the backbone of a computer, holding different...

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.
