The computer's block diagram illustrates its main components and connections. Input devices receive data, which the CPU processes. The CPU comprises the ALU, Control Unit, and registers. Memory holds data and instructions, while output devices display results. Learn more - https://goglobalways.com/blog/a-block-diagram-of-the-digital-computer-system/

2. A computer's block diagram is a visual
representation of its major components and how
they are interconnected. It provides a high-level
overview of the computer's architecture and
helps to understand how data flows and is
processed within the system.

3. Input Devices:
These devices allow users to interact with the
computer and provide input data and
instructions. Common input devices include:
Keyboard: Used for typing text and entering
commands.
Mouse: Used for pointing and clicking on graphical
user interfaces.
Touchscreen: A display with touch-sensitive
capabilities.
Scanner: Used to convert physical documents or
images into digital format.

4. Central Processing Unit (CPU):
Arithmetic Logic Unit (ALU): Performs arithmetic
(addition, subtraction, multiplication, division) and
logical (AND, OR, NOT) operations on data.
Control Unit: Coordinates and manages the
execution of instructions, fetching them from
memory and decoding them to control other
components.
Registers: Small, fast storage locations within the
CPU used to temporarily hold data and intermediate
results during processing.
The CPU is the core processing unit of the computer
responsible for executing instructions and performing
calculations. It consists of several key components:

5. Cache:
The cache is a small, high-speed memory located close to the CPU.
It stores frequently accessed data and instructions to reduce the
time it takes for the CPU to access data from the main memory
(RAM).

6. Main Memory (RAM - Random Access Memory):
Volatile memory that holds data and instructions
currently in use by the CPU. When the computer
is powered off, the data in RAM is lost.
Secondary Storage: Non-volatile memory used
for long-term storage of data even when the
computer is powered off. Examples include hard
disk drives (HDD) and solid-state drives (SSD).
The computer's memory holds both data and
instructions necessary for the CPU to process. It
consists of different types of memory:
Memory:

7. Monitor/Display: Shows visual output,
such as text, images, and videos.
Printer: Produces hard copies of
documents and images.
Speakers: Output audio and sound.
These devices display or present information
processed by the computer to the user.
Common output devices include:
Output Devices:

The block diagram of computer provides a simplified view
of the computer's architecture, and real computers can
have more complex arrangements and specialized
components depending on their intended use and design.
