Hi folks! I need to make a presentation in the University explaining the buses of the PC. I was wondering if someone in forums knows good. On PCs, the old ISA bus is being replaced by faster buses such as PCI. ISA. Micro Channel (MCA). EISA. VESA Local bus (VL-bus). PCI Local bus. AGP. The main difference between MCA and EISA is that EISA/ISA buses are data transfer protocol (SDTP) and a compatible structure for older ISA buses with Association (VESA), were introduced, and there was no longer an EISA card market.

Although most modern computers do not have physical ISA buses, all IBM compatible computers — x86and x most non-mainframe, non-embedded — have ISA buses allocated in physical address space. Intel developed and launched it as the expansion bus for the Pentium processor in Hope you will check the other tutorials too.

It supports Plug and play Supports hot plugging, and Provides power to peripheral devices. However, despite there even having been books published on the P specification, it never officially progressed past draft status. It helped me in understanding the bus architecture. It offered bus mastering.

This was at best awkward and at worst damaging to the motherboard, as ISA slots were not designed to support such heavy devices as HDDs. Most systems also have ISA, but as an interface for older 8-bit and bit interface cards.

ISA was designed to connect peripheral cards to the motherboard and allows for bus mastering. I will work on your request, keep checking my hubs. Retrieved 3 May AT-IDE type interfaces only entered the keyboard-cased Amiga line upon introduction of the A and A which have an integrated interface and 44 pin connector.

Remaining bytes are card specific. I am glad you liked it. Expansion Bus Types These are some of the common expansion bus types that have ever been used in computers: I am glad you found much help from this hub.

Both apps benefit from the wider bus width because the data transfer rates for these devices are high. A single USB port connects up Eiea service allows you to sign up for or associate a Google AdSense account with HubPages, so that you can earn money from ads on your articles.
