Expansion Slots on Motherboard

An expansion slot on a motherboard is a socket for an expansion card to be connected. Different types of expansion slots are available to accommodate different types of expansion cards. The three most common types of expansion slots are ISA, PCI, and AGP.

Types of Motherboard Expansion Slot

a) ISA:
- ISA stands for Industry Standard Architecture.
- It was the first type of expansion slot introduced in the mid-1980s.
- It was used to connect slower peripherals such as modems and sound cards.
- It is no longer used in modern computers.

b) PCI:
- PCI stands for Peripheral Component Interconnect.
- It was introduced in the early 1990s.
- It is a faster and more versatile slot than ISA.
- It can be used to connect a wide range of peripherals such as sound cards, network cards, and video cards.

c) AGP:
- AGP stands for Accelerated Graphics Port.
- It was introduced in the late 1990s.
- It was specifically designed to connect video cards.
- It is no longer used in modern computers.

d) ATX:
- ATX stands for Advanced Technology Extended.
- It is not an expansion slot but rather a form factor for motherboards.
- It defines the physical size and layout of the motherboard.
- It provides additional power and cooling capabilities compared to older form factors like AT.

Answer:
The correct answer is option 'C', AGP. AGP is not a type of motherboard expansion slot anymore as it has been replaced by PCI Express (PCIe) which is a faster and more versatile slot for connecting video cards.
