What is the socket on the motherboard into which an expansion card can be installed?
The sockets on the outside of a computer that plug into an expansion card are called ports. Depending on the expansion card, there can be a variety of ports including USB, audio and network ports.
What is the name for the routine that tests the motherboard?
The name for the routine that tests the motherboard memory disk controllers is POST-Power On Self-Test
What term is used to refer to the speed of a CPU?
CPU speed is measured in megahertz MHz and gigahertz GHz. Your typical processor is going to be in GHz if you have a super computer then it will be in MHz. The CPU speed can be deceiving so make sure you do your research on them.
What if a motherboard support dual channeling but you have four DIMMs available that differ in size?
If you install DIMMS in all four slots that don't match, the memory will still work, just not at top performance.
What is purpose of a CNR slot?
Communications and Network Riser (CNR) is a interface on a computer motherboard for interfacing a communication device or peripheral. There have been several competing configurations but none of them seem to have really taken the lead.
This article puts it a little better perspective:
= The Strange Case of the AMR/CNR/ACR Slot =
article by: Demir Cutts
=== === Nearly everything inside a PC is designed to be user-installable. The Audio Modem Riser (AMR), Communications and Networking Riser (CNR), and Advanced Communication Riser (ACR) slots are exceptions. Although their presence on many recent motherboards intrigues some upgraders, these slots were never intended as general-purpose expansion slots. All of them were designed to be used by OEM system builders, not by backyard mechanics. Here's what you need to know about AMR, CNR, and ACR slots ; AMR slot : Intel developed the AMR slot to provide an easy, standardized way to integrate modem and audio functions into finished systems at minimal cost, but OEM system builders ignored it in droves. Why? Mainly because the AMR slot took the place of a standard PCI slot, and most motherboard designers and system builders rightly preferred having an extra PCI slot to having an AMR slot of dubious utility. The AMR slot also had limited functionality and no support for Plug and Play. The result was that, although some motherboards included an AMR slot, very few AMR-compatible cards were ever developed and those that were achieved only limited distribution. We've seen exactly one AMR card. ; CNR slot : Intel's answer to the problems of AMR was to redesign the AMR slot. The CNR slot, can coexist with a standard PCI slot, allowing either a CNR card or a standard PCI card to use the slot position interchangeably. CNR also adds Plug and Play support and other features of interest to system designers. AMR and CNR are incompatible, at both the physical and electrical level. Although we have seen a few CNR cards, mostly modems and sound adapters, CNR cards are not much easier to find than AMR cards. ; ACR slot : AMR and CNR are both Intel technologies. AMD, VIA and the rest of the everyone-who-is-not-Intel camp came up with an alternative called the ACR slot, which is found on some Intel-free motherboards. The ACR slot is physically a standard PCI slot connector, which you can recognize because it's turned 90 degrees to the other PCI connectors on the motherboard. In theory, the ACR slot offers several advantages over the AMR/CNR slot, including its use of standard connectors and its additional flexibility because of the greater number of available pins. In practice, we've never seen or even heard of a card designed to fit that slot, so it is effectively a wasted connector. Intel warns that the AMR and CNR interfaces are not rigidly defined, so it is quite possible that any given AMR or CNR card simply will not work in a particular AMR or CNR slot. If your motherboard has an AMR, CNR, or ACR slot, we suggest you pretend it's not there.
Is motherboard device a input or output?
A motherboard takes both input and output. For example, it may take inputs from a keyboard or mouse, and output video from an integrated graphics card.
In a more general sense, the motherboard is the device which connects all of the pieces of the computer together; All of the data sent between devices is routed through the motherboard. In effect, every one of these data transmissions can be viewed as input and output (input data from one device to the mobo, output the data from the mobo to another device).
What is a 20 pin ATX power connector?
The atx 12 connector is one of the motherboard power connectors and used for 12 volt power connect for cpu voltage regulator.
Working principle of keyboard?
the keboard work as:
Inside the keyboard, there are metallic plate, circuit board (key matrix) and processor, which are responsible for transferring information from the keyboard to the computer. Depending upon the working principle, there are two main types of keys, namely, capacitive and hard-contact. Let's discuss in brief about the functioning of capacitive and hard contact key.
Capacitive Key
On the underside of a capacitive key, a metal plunger is fixed, which helps in activating the circuit flow. When a capacitive key is pressed, the metal plunger applies a gentle pressure to the circuit board. The pressure is identified by the computer and the circuit flow is initiated, resulting in the transfer of information from the circuit to the currently installed software.
Hard Contact Key
A hard contact key is attached with a metallic plate that helps in connecting the circuit board. When the hard contact key is pressed, it pushes a metallic plate, which in turn touches the metallic portion of the circuit plate. This overall process of completing a circuit results in a circuit flow, allowing the transfer of the message to the central processing unit (CPU), which is further transmitted to the software.
In both the key types, the circuit signals the processor to read and/or identify the character that has been pressed. For example, in a hard contact key, the processor reads that pressing 'shift' and 'a' keys at the same time corresponds to 'A'. Hence accordingly, the letter, sign or symbol is displayed on the screen. Releasing the pressed key breaks the circuit flow, after which the key retains its original position. The communication between a computer keyboard and main computer is bi-directional, meaning that message or information can be sent within each other.

Correction: a socket T is a LGA 775 package which means that it has a 775 pin CPU which fit into a 775 contact(not pin receiver) socket on the motherboard. A socket N is a mPGA478B package meaning a 478 pin CPU that will fit in a motherboard with a 478 pin hole receiver socket. ~Yagon~
What components go on the motherboard?
1. AGP(accelerated graphics port) edit: now replaced with PCIx (PCI Express) ex 2010
2. Chip set
3. CPU (central processing unit)
4. bios edit: now replaced with the UEFI firmware ex 2014
AGP or Accelerated Graphics Port slots are used for graphics cards. Display quality is significantly enhanced when using AGP video cards.
Does a PCI expansion card just slot in a PC's motherboard?
A PCI card is supplied with an edge connector which fits snugly into a PCI slot on the motherboard. Firm pressure is needed to ensure the card makes a good connection with the slot. There is also a metal plate along another edge of the card which allows the user to fix the card to the computer case with a screw. Before the card is inserted into the PCI slot the blank plate in the back of the case next to the slot must be removed. Most PCI cards provide connectors on the metal plate to allow external devices to be linked up to the computer; these might be display monitors, joysticks, audio connections etc.
What does the motherboard hold?
The motherboard holds most of the essential circuitry needed for the computer. It contains the CPU, the chipset, the buses, the memory, voltage regulators, the BIOS, the CMOS battery, and various controllers. The motherboard may or may not have integrated graphics. If not, the machine will need a separate video card.
What is latest graphic card price and model number?

What are the three approaches to selecting a motherboard?
1. Select the board that provides the most room for expansion.
2. Select the board that best suits the needs of the computer's current configuration.
3. Select a motherboard that meets your present need with moderate room for expansion.
Why is it best to install drives into a computer case before you install the motherboard?
Because you might drop the drives on your motherboard while installing.
What is part of the motherboard and connects the processor to main memory?
Front side bus, which is part of the mother board
What are the parts of a motherboard and its function?
- CPU Socket - This holds the CPU or central processing unit of the computer. A CPU does most of the heavy lifting and thinking inside of a computer.
- RAM slots - These hold the RAM, or Random Access Memory. RAM is the workbench in your computer, holding all of your open programs for you.
- North Bridge - This chip is usually located right beneath the CPU socket and its usual functions are to communicate effectively between the CPU, RAM, Graphics Chips, and South Bridge on your computer.
- South Bridge - This chip handles all the communication between all the other input/output devices on your computer (USB ports, mouse, keyboard, speakers, etc.) and the North Bridge
- PCIe, PCI, AGP and ISA card slots - These slots are used to expand the capabilities of your motherboard, from TV tuners for watching TV to a better sound card for your 7.1 channel surround sound system.
- Front Panel pin out - This is usually a group of 9 pins that connects the power and reset buttons, and the power and hard drive lights on the front of your computer to the motherboard.
- USB and audio pin-outs - These connect to a cable that runs to the front of your computer so that you can have front facing USB and audio ports.
- Back IO Connector - This is usually where you plug in most of your stuff on your computer and usually has your keyboard and mouse ports, USB ports, Video connector, audio jacks, network jack, among others.
- SATA, IDE, and Floppy connectors - These connect up to the main storage devices on your computer, including your hard drive, DVD/CD drive, and of course, the floppy drive on the front of your computer.
- BIOS - This holds the information your motherboard needs to start itself, and also keeps track of the current time.
Which motherboard is best for graphics software?
This is a tough question to answer for a couple of reasons. First off: There are a lot of motherboards to choose from and there isn't really 1 out there that is absolutely the best. Intense graphics design requires some of the best hardware you can get and the motherboard is only 1 of many things to decide on. The Video Card, Processor and RAM are probably the most important things you will need to choose. The higher the frequency of the FSB (Front Side Bus) the less likely it will be a bottleneck for your graphics. If you are willing to pay a lot of money for a really nice system I could suggest some kind of dual processor board, a PNY video card, and a lot of fast RAM. A good recourse for motherboards is www.mbreview.com There you will be able to find some excellent reviews on the latest motherboards. Some of my favorite brands are AOpen, Chaintech and MSI. They seem to be very reliable.
Asus, Gigabyte and Intel are three very good mb makers. If you're looking for extreme high-end, Gigabyte has a new MB with FOUR x16 slots, taking SLI to a new level.
If you are looking at using Vista, it's the video card(s) that need the attention, because available RAM is limited to less than 4MB, so the big factor is to get onboard (unshared) memory on your graphics card -- you don't want shared memory, which is going to subtract from RAM available to the CPU. With Win7, this is less of a problem.
If you like AMD, the Gigabyte GA-MA790GP-UD4H looks pretty good on the high end. It has 128mb of "side-port" memory that, as I understand it, is dedicated to graphics. I don't think it's a bit deal but it is a plus.
What is a 20 Pin P1 Connector?
Many different connectors can have 20 pins. Some examples of these are:
- ATX power supply connectors
- JTAG cables (used for programming embedded devices)
- A proprietary OBDII connector found in some BMW vehicles
- HDMI cables / connectors (used for high-definition video)
- Very old Apple floppy drives
What must be true before motherboard?
A motherboard must be modified to accept a particular type of memory, especially when dealing with multi-channel memory. On most motherboards, several types of modes can be configured to run at the same time. It is best to read the manual that came with your motherboard to find out how to correctly configure yours.
What is the difference between a motherboard and a daughter board?
The motherboard is the base board into which the others connect. It is central to the function of the system interconnecting all the rest while the daughter boards typically provide functions non-essential to the system being logically functional (with the exception that sometimes a processor itself is on a daughterboard).
Will a ddr3 1066 RAM work in a ddr3 1800 slot?
Of course, it could be run. It doesn't actually matter what type of ddr3 ram it is but what matters is the slot type and the ram type. DDR1 DDR2 DDR3 all have different slots. So as far as I think, It is going to work. Check it out and tell me..
