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.

Expansion Bus Types These are some of the common expansion bus types that have ever been used in computers: Archived from the original on 6 January I am happy that you were able to understand the computer bus architecture. This hub would have helped me.

Hope you will check the other tutorials too. Wishing you all the best.

Thanks Oluwasegun for reading and commenting on this ejsa. Thanks irfan for approving this work, I am glad you liked it. January Learn how and when to remove this template message. In reality, ISA PnP could be troublesome and did not become well-supported until the architecture was in its final days.

This article are too much informative PCI slots were the first physically-incompatible expansion ports to directly squeeze ISA off the motherboard. Motherboard devices have dedicated IRQs not present in the slots. Data sharing – All types of buses found in a computer transfer data between the computer peripherals connected to it.

One 8-bit and five bit ISA slots on a motherboard. PCI supports both bit and bit data width; it is compatible with s and Pentiums. To provide a better website experience, turbofuture.

When it first appeared the 8-bit ISA bus ran at a speed of 4. Views Read Edit Veas history. VESA Video Electronics Standards Association was invented to help standardize PCs video specifications, thus solving the problem of proprietary technology where different manufacturers were attempting to develop their own buses. This is an external bus standard that supports data transfer rates of 12 Mbps.

Am so much greatfull for this. Power – A bus supplies power to various peripherals connected to it. vsa

The next generation of Integrated Drive Electronics drives moved both the drive and controller to a drive bay nus used a ribbon cable and a very simple interface board to connect it to an ISA slot. Timing – The bus provides a system clock signal to synchronize the peripherals attached to it with the rest of the system.

Bus Structures Excerpted from www. This made it unpopular and it is now an eisz technology. 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. Thanks Ankit for reading and approving my work. 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.

Thank you very much, if you don’t mind. ATA is basically a standardization of this arrangement plus a uniform command structure for software to interface with the HDC within the drive. It was developed by apple with the name firewire. This is feature allows you to search the site.

The History of USB In a collaborative effort to design a standard for peripheral devices was made between Compaq. So it is basically used in the small computers. Intel developed and launched it as the expansion bus for the Pentium processor in Now concerning your question, the processor relies on the timing signal which syncronizes the activities taking place in the computer. Computers have two major types of buses:
