What is MCA architecture?
What is MCA architecture?
Micro Channel Architecture (MCA) is a proprietary 32 and 16-bit bus developed for IBM’s PS/2 computers. Introduced in 1987, the MCA was designed to replace the smaller AT and industry standard architecture (ISA). In 1988, Intel developed its version of the MCA chip, known as the i82310.
What is the expansion of MCA?
Master of Computer Applications or MCA is a professional degree in computer science. MCA is a two year long professional post-graduate degree course for students who deeply want to learn computer application development.
What is the advantage of MCA bus?
MCA busmasters can even use the bus to talk directly to each other at speeds faster than the system CPU, without any other system intervention. Arbitration enhancement also provides that we have better system throughput since control is passed more efficiently.
What is EISA in computer?
The Extended Industry Standard Architecture (in practice almost always shortened to EISA and frequently pronounced “eee-suh”) is a bus standard for IBM PC compatible computers. The bus mastering support is also enhanced to provide access to 4 GB of memory.
What is the use of MCA course?
“MCA (Master of Computer Applications) is a professional master’s degree in computer science. It focuses on providing a theoretical as well as practical training to students in the related field.” Computer Applications is a use of computer to solve a problem or to accomplish a particular job.
What does bus mean in computing?
A bus is a high-speed internal connection. Buses are used to send control signals and data between the processor and other components. Three types of bus are used. Address bus – carries memory addresses from the processor to other components such as primary storage and input/output devices.
What is taught in MCA?
MCA course provides in-depth and extensive knowledge about various aspects of computer applications. Students are taught everything related to software, hardware, and networking with the studies of IT, Data structures & Mathematics. MSc Computer Science provides core competence in various aspects of Computer Science.
What is the difference between ISA and EISA?
The EISA bus is compatible with older ISA buses with 8-bit or 16-bit data paths. EISA connectors are 16-bit superset connectors for ISA system boards, providing more signals and enhanced performance. The main difference between MCA and EISA is that EISA/ISA buses are backward compatible.
What are the salient features of PCI bus?
What are the features of PCI (peripheral component interconnect) bus?
- Singling Environment : Support both 3.3 and 5 volt signaling environments.
- Reliability: It offers the ability to replace modules without disturbing a system’s operation called as hot plug and hot swap.
- Speed: It can transfer up to 132 MB per second.
What is VESA in computer?
VESA is an acronym that stands for the Video Electronics Standards Association. The VLB is an older local bus architecture popular on 486 computer systems in 1993 and 1994. PCI and AGP bus architectures have completely replaced the VLB.
What are PCI expansion slots?
PCI: The PCI slot is the most common form of internal expansion for a PC. AGP: This type of expansion slot was specifically designed to deal with graphics adapters. In fact, AGP stands for Accelerated Graphics Port. Older PCs may sport this expansion slot, but the best video cards use PCI Express.
What is a Micro Channel Architecture (MCA)?
Stands for “Micro Channel Architecture.” It is an expansion bus created by IBM that was used in the company’s PS/2 desktop computers. An expansion bus allows additional cards to be connected to the computer’s motherboard, expanding the number of I/O ports. These include SCSI, USB, Firewire, AGP, and DVI connections, as well as many others.
What is a Micro Channel bus?
Micro Channel architecture From Wikipedia, the free encyclopedia 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. Its name is commonly abbreviated as “MCA”, although not by IBM.
What is a micro channel card?
A lot of the Micro Channel cards that were developed used the CHIPS P82C612 MCA interface controller; allowing MCA implementations to become a lot easier. The Micro Channel was primarily a 32-bit bus, but the system also supported a 16-bit mode designed to lower the cost of connectors and logic in Intel-based machines like the IBM PS/2 .
What factors led to the development of Micro Channel?
The development of Micro Channel was driven by both technical and business pressures. The IBM AT bus, which later became known as the Industry Standard Architecture (ISA) bus, had a number of technical design limitations, including: A slow bus speed. A limited number of interrupts, fixed in hardware.
