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.
Where can you get a driver for Pinnacle Miro DC10?
A Google search produces some links to the Pinnacle sys website and some for a Linux driver. The Pinnacle sys site shows only win 9x drivers and a link to a Linux 3rd party driver. It also calls this a legacy product. If that driver doesn't work, the outlook is grim.
Electronic instructions that the computer hardware uses?
When a computer starts up it needs to check various things that may stop the computer from starting properly. These instructions are contained in the micro-processor that is installed as part of the computer. These instructions are long, detailed, and what most people normally do not worry about
Discuss the hardware support required to support demand paging?
For every memory access operation, the page table needs to be consulted to check whether the corresponding page is resident or not and whether the program has read or write privileges for accessing the page. These checks would have to be performed in hardware. A TLB could serve as a cache and improve the performance of the lookup operation.
Is Intel Graphics Media Accelerator 4500 MHD good for gaming?
Hey X4500 is allright ! I played Far Cry 2 , NFS undercover and Kane n Lange they all worked on medium graphics wheras Fifa09 was working not very well ! So buy it if u plan to buy a 3d card in future !!!
What are the three common components of computer?
central processing unit comprising of arithmetic logic unit and control unit, and RAM i.e.the internal memory
Where does a computer store the program when its power is on?
Set of instructions are called programs. All the programs given to computer are first stored in backing storage device like hard disk, magnetic disk, CDs, DVDs. When user wish to run these instructions, these are loaded in Computer Primary Memory i.e. RAM. Form RAM these instructions are read by processor and run.

How do ZIF sockets make it easier to remove and replace the processor?
"ZIF" is an anconym for "Zero Insersion Force".
For any processor, or other integrated circuit designed for insertion into a socket, the force required to insert or remove it is proportional to the number of pins on the chip. As each pin needs a secure connection to it's socket, the force required on modern processors, having close to a thousand pins; to insert into or remove from a socket reliably and without damage; would be extremely high and would likely cause physical damage if done by hand.
A ZIF socket utilizes a clamping mechanism whereby the socket contacts can be opened using a lever. This allows a processor, with hundreds of fragile pins, to simply be dropped into the socket with no force. Then, the ZIF socket is clamped or "locked" using the lever which firmly clamps all pins tightly.
In this manner, a ZIF socket makes difficult and potentially damaging insertion or removal of a processor or other integrated circuit, a simple, easy, and safe task.
Microsoft Office 2003 & 2007 (excel and word) to be exact.
An absolute loader is the simplest type of loader scheme that fits the general model of loaders. The assembler produces the output in the same way as in the "complier and go loader" . The assembler outputs the machine language translation of the source program.
Disadvantage:
- The programmer has to specify the address to the assembler that where the program is to be loaded.
- It is very difficult to realocate in case of multiple subroutine.
- Programmer has to remember the address of each subroutine and use that absolute address explicitly in other subroutines to perform subroutine linkage
Connections inside the computer case can cause a system to appear dead or reboot itself?
I would make sure all connections are secure tightly and well connected. Also make sure all outer connections like the connection from the monitor to the box is well connected.
Maybe the RAM sticks are not sitting tightly or check the cables to the hard drive that are well connected.
What is the main computing part on the PC?
The CPU (Central Processing Unit) is either a AMD or Intel processor. If you are using a desktop you will be able to locate it on the motherboard. Its under the heat sink/fan on your motherboard. Carefully remove your heat sink and you will find your cpu.
How do you decide which expansion card is the video card?
The main way to tell which expansion card is the video card is to look at the plug. If it has a VGA socket, a display port socket, HDMI, etc., then you will know it is a video card. You may identify some of the chips on the card as being RAM, or you might find a fan on it, but these features are not exclusive to video cards. If that is the place where you plug your monitor, then it is a video card, unless of course you are plugging directly into the motherboard.
Is a fork an example of a wedge?
No, a fence is not an example of a wedge. A fence post could be a wedge if it is pointed and designed to be pounded into the ground.
I Don't get your question, my VGA port works perfectly.
It was first conceived in 1972 by Alan Kay. The first flip form laptop was built in 1982 - it was the Grid Compass 1100.
