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.

Azirap, I am glad you learnt something from this tutorial. The XTA pinout was very similar to ATA, but only eight data lines and two address lines were used, and the physical device registers had completely different meanings. In addition to the physical interface channel, ATA goes beyond and far outside the scope of ISA by also specifying a set of physical device registers to be implemented on every ATA IDE drive and a full set of protocols and device commands for controlling fixed disk drives using these registers.

Can anybody help me? If you get sometime, remember to check the others. Date and year Articles lacking in-text citations from January All articles lacking in-text citations All articles with unsourced statements Articles with unsourced statements from April Commons category link is on Wikidata.

ATA is basically a standardization of this arrangement plus a uniform command structure for software to interface with the HDC within the drive.


One advantage of MCA was that the plug-in cards were software configurable; this means that they required minimal intervention by the user when configuring. This article are too much informative It helped me in understanding the bus architecture. I am glad you got what you eiisa from this article. From Wikipedia, the free encyclopedia.

Computers are very useful electronic devices that we use in modern world. Wikimedia Commons has media related to ISA. Unless you are signed in to a HubPages account, all personally identifiable information is anonymized.

Has plug and play PnP characteristics Has the ability to function with a bit data bus.

No data is shared unless you engage with this feature. Thanks a lot cablemanagements, for reading and commenting. Thanks Belbo Baigans and you are much. Thanks mugrewa julius for reading and commenting. PCI supports both bit and bit data width; it is compatible with s and Pentiums.

I am glad you liked the article. I will work on your request, keep checking my hubs. Your opinion here Did you get anything useful out of this hub? Thanks a lot Juzzman, for reading and commenting on my work.

In a newer vdsa USB 2. Inside computers, there are many internal components. Bus Structures Excerpted from 1.

This pathway is used for communication purpose buss it is established between two or more computer components. No data is shared with Facebook unless you engage with this feature. Most PCI cards are designed for 5v, but there are also 3v and dual-voltage cards. PCI slots were the first physically-incompatible expansion ports to directly squeeze ISA off the motherboard.


Buses are classified depending on how many bits they can move at the same time, which means that we have 8-bit, bit, bit or even bit buses. Thanks Patrick Pic for this timely piece of information. Different Types of Computer Buses. Is adapters protodols work in either slot Each PCI card contains a byte configuration memory. Timing – The bus provides a system clock signal to synchronize the peripherals attached to it with the rest of the system.

It has four DMA channels originally provided by the Intel3 of the DMA channels are brought out to the XT bus expansion slots; of these, 2 are normally already allocated to machine functions diskette drive and hard disk controller:.

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 am very pleased to learn about computer buses. Sign in or sign up and post using a HubPages Network account. Sia for the comment and keep visiting.

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

Thank you very much, if you don’t mind.
