1.	The full form of PCI in the context of microcontrollers is:1. Peripheral Component Interconnect2. Personal Computer Interface3. Personal Computer Information4. Peripheral and Component Information
Answer» Correct Answer - Option 1 : Peripheral Component Interconnect PCI stands for Peripheral Component Interconnect In computer architecture, a bus is a subsystem that transfers data or power between computer components inside a computer or between computers. A bus can logically connect several peripherals over the same set of wires. Each bus defines its set of connectors to physically plug devices, cards or cables together. Types of Buses: 1. Peripheral Component Interconnect (PCI) Bus: It specifies a computer bus forattaching peripheral devices to a computer motherboard. These devices can be in the form ofintegrated circuitsfitted on the motherboard itself orexpansion cardsthat fit in sockets. It is designed to support a single as well as microprocessor systems. It has ahigh bandwidth. Itdelivers better system performancefor high-speed I/O subsystems (e.g. graphic display adapters, disk controllers, etc.) 2. Universal Serial (US) Bus:It provides a serial bus standard for connecting devices, usually to computers such as personal computers. It has an asymmetric design, consisting of a host controller and multiple devices connected in a tree-like fashion using special hub devices, called USB hubs.

Answer» Correct Answer - Option 1 : Peripheral Component Interconnect

PCI stands for Peripheral Component Interconnect

In computer architecture, a bus is a subsystem that transfers data or power between computer components inside a computer or between computers. A bus can logically connect several peripherals over the same set of wires. Each bus defines its set of connectors to physically plug devices, cards or cables together.

Types of Buses:

1. Peripheral Component Interconnect (PCI) Bus:

It specifies a computer bus forattaching peripheral devices to a computer motherboard.
These devices can be in the form ofintegrated circuitsfitted on the motherboard itself orexpansion cardsthat fit in sockets.
It is designed to support a single as well as microprocessor systems.
It has ahigh bandwidth.
Itdelivers better system performancefor high-speed I/O subsystems (e.g. graphic display adapters, disk controllers, etc.)

2. Universal Serial (US) Bus:It provides a serial bus standard for connecting devices, usually to computers such as personal computers. It has an asymmetric design, consisting of a host controller and multiple devices connected in a tree-like fashion using special hub devices, called USB hubs.
