Micro Channel architecture, or the Micro Channel bus , was a proprietary 16- or 32-bit parallel computer bus introduced by IBM in 1987 which was used on PS/2 and other computers until the mid-1990s.
What is bus EISA bus?
Extended Industry Standard Architecture (EISA) is a bus architecture that extends the Industry Standard Architecture (ISA) from 16 bits to 32 bits . ... EISA was designed to compete with IBM’s Micro Channel Architecture (MCA) – a patented 16 and 32-bit parallel computer bus for IBM’s PS/2 computers.
Which processor is used in PC at?

What is an ISA bus used for?
An Industry Standard Architecture bus (ISA bus) is a computer bus that allows additional expansion cards to be connected to a computer’s motherboard . It is a standard bus architecture for IBM compatibles.
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.
How is bus bandwidth calculated?
Calculating bandwidth for a data bus is like the following in a text I read: “The bus cycle speed is 200 MHz with 4 transmits of 64 bits per clock cycle. The bus bandwidth is then 200*4*64/8 =800*64/8 MBytes per second which is 6400 MBytes per second.”
What is System bus?
The computer system bus is the method by which data is communicated between all the internal pieces of a computer . It connects the processor to the RAM, to the hard drive, to the video processor, to the I/O drives, and to all the other components of the computer.
What are the 3 types of CPU?
- Single-core CPU. It is the oldest type of CPU which is available and employed in most of the personal and official computers. ...
- Dual-core CPU. ...
- Quad-core CPU. ...
- Hexa Core processors. ...
- Octa-core processors. ...
- Deca-core processor.
Which is better RAM or processor?
RAM is essentially the core of any computer or smartphone and in most cases, more is always better . RAM is as significant at the processor. A right amount of RAM on your smartphone or computer optimizes performance and the ability to support various types of software.
What is the full form of IBM PC?
IBM, in full International Business Machines Corporation , leading American computer manufacturer, with a major share of the market both in the United States and abroad. Its headquarters are in Armonk, New York.
How does a PCI bus work?
PCI is a 32-bits bus, and so has 32 lines to transmit data . At the beginning of a transaction, the bus is used to specify a 32-bits address. Once the address is specified, many data cycles can go through. The address is not re-transmitted but is auto-incremented at each data cycle.
What is the difference between PCI E x16 expansion slot and AGP expansion slot?
A PCI-Express interface only works with a PCI-Express graphics card. An AGP interface only works with an AGP graphics card. The main difference is speed . PCI-Express is newer, and the highest PCI-Express speed is x16.
What is full form ISA?
Industry Standard Architecture (ISA) is a computer bus standard for IBM PC compatible computers introduced with the IBM Personal Computer to support its Intel 8088 microprocessors 8-bit external data bus and extended to 16 bits for the IBM Personal Computer Intel 80286 processor.
Is RISC-V better than ARM?
In general, the RISC approach is more successful in reducing overall power consumption , sometimes at the expense of lower performance. However, the lines of difference are narrowing. ARM has added more complex instructions to increase processor performance (at the expense of higher power consumption).
Is RISC dead?
EDIT: Its really, really difficult for me to consider ARM a real RISC machine. ... RISC vs CISC debate is dead , and has been for decades. ARM just takes good designs, just as all the other CPU designers do. If its a good design, it goes into the chip.
Does ISA bus supports plug and play?
ISA PnP or (legacy) Plug & Play ISA was a plug-and-play system that used a combination of modifications to hardware, the system BIOS, and operating system software to automatically manage resource allocations. It was superseded by the PCI bus during the mid-1990s.
