What is AMR in motherboard?

The audio/modem riser (AMR ) is a riser expansion slot found on the motherboards of some Pentium III, Pentium 4, Duron, and Athlon personal computers. It was designed by Intel to interface with chipsets and provide analog functionality, such as sound cards and modems, on an expansion card.

What is CNR motherboard?

Communications and networking riser (CNR) is a slot found on certain PC motherboards and used for specialized networking, audio, and telephony equipment. A motherboard manufacturer can choose to provide audio, networking, or modem functionality in any combination on a CNR card.

What is the full form of AMR in computer?

The Adaptive Multi-Rate (AMR, AMR-NB or GSM-AMR) audio codec is an audio compression format optimized for speech coding.

What is PCIe slot?

A PCIe or PCI express slot is the point of connection between your PC’s “peripheral components” and the motherboard.

What is ISA slot in computer?

Stands for “Industry Standard Architecture.” ISA is a type of bus used in PCs for adding expansion cards. For example, an ISA slot may be used to add a video card, a network card, or an extra serial port. Today, most computers only support PCI and AGP expansion cards.

What does PCI stand for PC?

Peripheral Component Interconnect
Peripheral Component Interconnect, or PCI, is the most common way to attach add-on controller cards and other devices to a computer motherboard. This type of connector originated in the early 1990s, and is still in use today.

Who uses AMR?

AMR audio files were originally created for use on 3G phones. This file format has been around for a while; it was developed by Ericsson in the 1990s. AMR files can be opened by several media players, including Apple QuickTime Player, RealNetworks RealPlayer, and VLC Media Player.

Is PCIe better than SSD?

Unlike SATA based SSDs, PCIe can allow more bandwidth through faster signalling and multiple lanes. Due to the direct connection to peripherals, SSDs based on PCIe perform much better than the SATA counterparts that uses cables to connect to the motherboard, which in turn results in high latency.

Is ISA still used?

Even though ISA disappeared from consumer desktops many years ago, it is still used in industrial PCs, where certain specialized expansion cards that never transitioned to PCI and PCI Express are used.

When did Amr come out for motherboard?

Released September 8, 1998, AMR is short for audio/modem riser and allows OEMs to make one card with the functionality of either a Modem or audio or both as one card. This specification allows for the motherboard to be manufactured at a lower cost and free up industry standard expansion slots in the system for other additional plug-in…

What does Amr stand for in computer category?

AMR Updated: 06/22/2018by Computer Hope Released September 8, 1998, AMR, short for audio/modem riser, allows OEMsto make one card with the functionality of either a Modem or audio or both as one card.

When was the audio modem riser ( AMR ) introduced?

The AMR slot was first introduced by Intel in 1998 as a way to allow motherboard manufacturers to use an analog input/output (I/O) system for audio and modem functions on an expansion board. Also known as an AMR slot.

Where is the AMR slot on a computer?

In the past, an internal modem was installed in one of several slot s inside the computer chassis and an external modem was plugged into a serial port at the rear of the computer. With AMR design, the slot can now be used for other purposes.
