2. What is a computer hardware? Name basic hardware components of a computer system.

Computer hardware refers to the physical components of a computer system that you can see and touch. These components work together to enable the computer to perform tasks. Here are the basic hardware components of a computer system:

Basic Hardware Components

1. Central Processing Unit (CPU): The primary component that processes instructions and performs calculations. Often called the "brain" of the computer.

2. Motherboard: The main circuit board that houses the CPU, memory, and other essential components, providing connections for communication between them.

3. Memory (RAM): Random Access Memory temporarily stores data and instructions that the CPU needs while performing tasks. It is volatile, meaning it loses its content when the power is turned off.

4. Storage Devices:

   • Hard Disk Drive (HDD): A traditional storage device that uses spinning disks to read/write data.
   • Solid State Drive (SSD): A faster storage device that uses flash memory to store data, with no moving parts.

5. Power Supply Unit (PSU): Converts electrical power from an outlet into usable power for the computer's components.

6. Input Devices: Hardware used to enter data into the computer. Common examples include:

   • Keyboard: For typing text and commands.
   • Mouse: For navigating the user interface.

7. Output Devices: Hardware that conveys information to the user. Common examples include:

   • Monitor: Displays visual output from the computer.
   • Printer: Produces a physical copy of digital documents.

8. Graphics Processing Unit (GPU): A specialized processor designed to handle graphics rendering, often used for gaming, video editing, and other graphics-intensive tasks.

9. Network Interface Card (NIC): Allows the computer to connect to a network (wired or wireless) for internet access and communication with other devices.

10. Cooling System: Includes fans or liquid cooling solutions to dissipate heat generated by the CPU and other components.

These components work together to enable the functionality and performance of a computer system.
