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.

You are welcome Marikoh, I am happy that you learnt something from this article.

It supports Plug and play Supports hot plugging, and Provides power to peripheral devices. It was developed by apple with the name firewire. I am glad you like it. This is an external bus standard that supports data transfer rates of 12 Mbps. besa

Data transfer rates are 12Mbps full speed, 1. Thanks fidel for appreciating the work done.

What is Extended Industry Standard Architecture (EISA)? – Definition from Techopedia

Thank you very much, if you don’t mind. This article is based on material taken from the Free On-line Dictionary of Computing prior to 1 November and incorporated under the “relicensing” terms of the GFDLversion 1. This allows data to be sent to or from specific memory locations. Good articlegood writing, good enough to be understood by any users at any level.

The USB also supports hot plugging or insertion ability to connect a device without turning the PC of and plug and play You connect a device and start using it without configuration. I have a short time for finding that please help me: Sync field, packet id, Information field, and CRC. Chapter 4 Making Connections. Share buttons are a little bit lower.


Registration Forgot your password? From Wikipedia, the free encyclopedia. It extends the XT-bus by adding a second shorter edge connector in-line with the eight-bit XT-bus connector, which is unchanged, retaining compatibility with most 8-bit cards.

Not only this but it also helped me in preparing notes: January Learn how and when to remove this template message. To use this website, you must agree to our Privacy Policyincluding cookie policy. A single USB port connects up to peripheral devicessuch as mice, modems, and keyboards.

Burd, Chp — Englander, Chp 7 p. However, with the popularity of the AT-architecture and the bit ISA bus, manufacturers introduced specialized pin connectors that integrated the two sockets into one unit. Retrieved 3 May Azirap, I am glad you learnt something from this tutorial. A PIC transaction takes place between ubs master a device takes control of the system busesand a target a device that only responds to access requests. I am glad you got what you wanted from this article.

Comments are not for promoting your articles or other sites. This was at best awkward and at worst damaging to the motherboard, as ISA slots were not designed to support such heavy devices prohocols HDDs.

Industry Standard Architecture

The earliest versions of the ATA standard featured a few simple protocols and a basic command set comparable to the command sets of MFM and RLL controllers which preceded ATA controllersbut the latest ATA standards have much more complex protocols and instruction sets that include optional commands and protocols providing such advanced optional-use features as sizable hidden system storage areas, password security locking, and programmable geometry translation.

Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. One 8-bit and five bit ISA slots on a motherboard. Microsoft ‘s PC 99 specification recommended that ISA slots be removed entirely, though the system architecture still required ISA to be present in some vestigial way internally to handle the floppy driveserial portsetc.


We are going to check different computer bus architectures that are found in computers.

I am very pleased to learn about computer buses. Thanks a lot cablemanagements, for reading and commenting.

Bus Interface ISA (Industry Standard Architecture) VESA local bus

Expansion Bus Types These are some of the common expansion bus types that have ever been used in computers: Thanks a lot Juzzman, for reading and commenting on my work. This is the most common type of early expansion bus, which was protpcols for use in the original IBM PC.

I am glad you found much help from this hub. Remaining bytes are card specific. Now concerning your question, the processor relies on the timing signal which syncronizes the activities taking place in the computer. Your opinion here Did you get anything useful out of this hub? What are the characteristics of a bus?

The AT bus was backward compatible with its 8-bit predecessor and allowed 8-bit cards be used in bit expansion slots. Peripheral Component Interconnect PCI is one of the latest developments in bus architecture and is the current standard for PC expansion cards.
