🎰 Motherboard Expansion Slots and Bus Speeds - CompTIA A+ 220-901 - 1.2 - YouTube

In computing, the expansion card, expansion board, adapter card or accessory card is a printed circuit board that can be inserted into an electrical connector, or expansion slot, on a computer motherboard, backplane or riser card to add functionality to a computer system via the expansion bus.
The XT bus architecture uses a single Intel 8259 PIC, giving eight vectorized and prioritized interrupt lines. It has four DMA channels originally provided by the Intel 8237, 3 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 bus of a motherboard allows communication between different components, and standardized expansion slots provide a way to easily upgrade our computers. In this video, you’ll learn about the bus architectures and how to use expansion slots to customize our PCs.

PCI & ISA Slot Computers by EVS Computers

ISA was replaced with more advanced bus called PCI. PCI. The first type of expansion slot we need to be familiar with is the PCI orPeripheral Component Interconnect expansion slot. Although it is now being replaced with newer bus, we can still find it in many older computers. Image 228.2 – PCI Slots. PCI slots are usually colored white.

These assorted types of slots and expansion cards are ordinarily harmonious with each other. If a card and slot are designed to accept a wider bus or a faster bus speed, then it would typically default to a lower setting. PCIe, PCI Express, introduced lately as a standard for connecting devices to computers. The software is compatible with PCI.

Join Mike Meyers for an in-depth discussion in this video, The expansion bus, part of CompTIA A+ (220-901) Cert Prep: 2 Core Hardware.
The Altair 8800 was the first slot-type expansion card bus added to a microcomputer. It was developed in 1974-1975 by IBM Corp. The expansion slot opening is generally located on the back of a PC and provides an electrical connection to the motherboard for an expansion card. Screws are then used to attach the card to the slot for added security.
Magma’s 3 Slot PCI Expansion System provides a simple, cost-effective solution for expanding the capability of practically any computer, especially as PCI Express becomes the industry standard, the number of available PCI slots has been reduced or completely eliminated.

PCI Expansion SlotsThe server has five peripheral component interconnect (PCI) expansion slots. Four of the PCI slots support hot-plug PCI adapters. The remaining, non-hot-plug PCI slot supports only a short adapter. Many adapters provide bus-master capabilities, which enable the adapters to perform operations without interrupting the system.

Expansion slots for PCs come in two basic sizes: half-and full-size. Half-size slots are also called 8-bit slots because they can transfer 8 bits at a time. Full-size slots are sometimes called 16-bit slots. In addition, modern PCs include PCI slots for expansion boards that connect directly to the PCI bus.

Expansion Bus Chapter 5 Overview • In this chapter, you will learn to – Identify the structure and function of the expansion bus – Explain classic system resources – Identify the modern expansion bus slots – Install expansion cards properly – Troubleshoot expansion card problems Structure and Function of the Expansion Bus Connections
Your computer may have interface bus standards built in that have no external connectors. The expansion slots in a PC or Mac are typically PCI (Peripheral Component Interconnect), which displaced the older ISA standard in PCs and NuBus slots in Macs.
