Unit 1.1 - Hardware and Software

Define hardware and its role in computer systems.
Identify the main internal components of a computer, including the CPU, processor, and motherboard.
Differentiate between RAM and ROM and their functions in a computer system.
List common hardware components, such as graphics cards, sound cards, NICs, cameras, and storage devices.
Explain the functions of input and output devices in a computer system.

Hardware refers to physical components of a computer system such as the keyboard, mouse, monitor, motherboard, processor, and storage devices.
Hardware is responsible for inputting, processing, storing, and outputting data in a computer system.
The main internal components of a computer include the CPU (Central Processing Unit), motherboard, RAM (Random Access Memory), and storage devices such as hard disk drives (HDD) or solid-state drives (SSD).
RAM (Random Access Memory) is a volatile memory that temporarily stores data and instructions while the computer is running. ROM (Read-Only Memory) is a non-volatile memory that contains firmware, such as the BIOS, and cannot be modified.
Common hardware components include graphics cards, sound cards, NICs (Network Interface Cards), cameras, and storage devices such as HDD or SSD.
Input devices such as keyboards and mice allow users to input data into a computer system, while output devices such as monitors and printers display or output data from a computer system.
