This document provides an overview of computer organization and architecture. It discusses the functional units of a computer, including the CPU, memory, I/O devices, and bus. It also covers topics like instruction set architecture, memory hierarchy, instruction execution cycle, pipelining, parallelism, performance evaluation, Von Neumann and Harvard architectures, Boolean algebra, logic gates, combinational and sequential circuits, ALU, registers, I/O interface, interrupts, DMA, storage devices, RAID, and backup systems. The document concludes with the differences between computer organization and architecture.

1. Title:
Computer Organization and
Architecture

2. Introduction
Computer organization and
architecture are the two
fundamental concepts that
underpin the operation of modern
computers.This presentation
provides a comprehensive overview
of the key concepts,principles,and
components involved in these
areas.

3. Computer Organization
This section discusses the
functional units of a computer,
including the CPU,memory,I/O
devices,and bus.It also covers the
instruction set architecture and the
memory
hierarchy.
ComputerArchitecture
This section covers the instruction
execution cycle,pipelining,
parallelism,and performance
evaluation.It also discusses the Von
Neumann and Harvard architectures.

4. Differences between Computer Organization and
Computer Architecture
Computer Organization Computer Architecture
Computer Organization deals with a structural
relationship.
Computer Architecture deals with the functional
behavior of computer systems.
Computer Organization consists of physical units
like circuit designs, peripherals, and adders.
Computer Architecture comprises logical functions
such as instruction sets, registers, data types, and
addressing modes.
Computer Organization handles the segments of
the network in a system.
Architecture coordinates the hardware and
software of the system.
For designing a computer, an organization is
decided after its architecture.
For designing a computer, its architecture is fixed
first.
Computer Organization is frequently called
microarchitecture.
Computer Architecture is also called Instruction Set
Architecture (ISA).

5. Digital Logic
This section covers the Boolean algebra, logic
gates, and combinational and sequential
circuits. It also discusses the ALU and registers.
Input/Output Systems
Th is section covers th e I
/
O interface, interrupts,
DMA, and storage devices. It also discusses
the RAID and backup systems.

6. Conclusion
This presentation has provided a comprehensive overview of
the fundamentals of computer organization and architecture.
We have covered the key components,principles,and
concepts that underpin the operation of modern computers.
Thank you for your attention.
