How many types of land line modem?
Soft modems and dial up modems are some of the more dated modems that were created. They are considered to be land line modems since they used wired connections and ports.
What is riser and trade in architecture?
trade and riser are the terms used for stair case. trade is used for the breadth of and riser is used for height of stairs.
What are cellular modems used for?
There are three types of cellular modems - cell phones, aircards, and cellular routers. All three of these have the same purpose which is to connect a computer to the internet.
What is irq2 used for?
IRQ2 is used by old modems, and older video cards as an alternativeÊ IRQ for the third serial port or fourth serial port. It is used to cascade the second interrupt controller to the first.
Which types of cards are used for remote communications via phone lines?
modem cards
What are PC Cards?
These are slots (mostly in laptops) which lets you add features to your computer. I've seen network cards, modems, tv tuners, etc. be available for these slots. USB ports are making these slots used less and less.
What types of devices can be added using a PC card?
Theoretically, any type of device that can be installed in a computer can be connected through a PC card. In practice, it is used most often for network cards and modems. Video cards, SCSI controllers, USB hubs, GPS receivers, CompactFlash readers, and sound cards are all possible, but far less common than networking equipment for PC card / CardBus slots.
What are the advantages and disadvantages of modems?
Advantage: Modems not expensive. Higher transmission speed. Telephone can still be used. :)
What is the amr slot on a motherboard used for?
"AMRStands for (Audio/Modem Raiser) Which is used to convert analog audio to digital audio the card is said to be raiser because it raises the audio"Edit: That is incorrect. AMR stands for "Audio/Modem Riser". The AMR slot's purpose was similar to that of the, then standard, ISA slots, but specifically designed to accommodate smaller, inexpensive modem riser cards, audio riser cards and network riser cards. Intel introduced them on September 1998 as a way to reduce the total cost of computer systems by dividing the logic between the riser cards and their respective controllers on the motherboards.Later, Intel replaced AMR slots with CNR (communication and networking riser) slots. Though the two are similar, they slightly differ structurally and CNR cards also differed in two other areas: CNR supported Plug & Play cards and they offered the option to be either software based (via the CPU) or controlled by hardware acceleration (dedicated ASIC). To my knowledge though, riser cards that work in AMR slots also work in CNR slots. Neither slot gained popular acceptance by users, either initially or in time. This was likely because the riser cards relied on the CPU to handle alot of their workload, noticably slowing it down. So that's probably why you won't find AMR-compatible cards anywhere today. In 2000, ACR (Advanced Communications Riser) slots replaced both AMR and CNR, but ultimately integrated components made all three slots obselete.Sources:Wikipedia.orgAndrews, Jean. A+ Guide to Managing and Maintaining Your PC, 7th edition.Boston, MA: Cengage Learning, 2010. Print.Note:Nothing is "raised" (as suggested earlier by another user). The reason AMR slots accommodated audio cards is likely because it was it was a low priority component (in terms of the bus traffic going to the south bridge and CPU). Regardless of this, analog to digital audio conversions occur on integrated circuits on the sound card and doesn't raise the volume or any other aspect of the audio data (or data on modem/network cards for that matter).
Which RG rating of coax is used for cable modems?
Cable modems use RG-6 coax cables.
What are Different Types of Credit Cards used in India?
the Punjab card
Analog extensions on a private branch exchange are used typically to support which types of device?
Fax machines standard phone instruments PBX management modems
