Study Notes
Computing Platform
- Fundamental hardware and software infrastructure supporting software applications.
- Logic operations are jobs expressed in a number of steps to achieve a defined goal.
Theory of Computation
- Focuses on understanding how computers solve problems and handle information.
- Investigates the limits and capabilities of computer systems.
- Aims to develop new algorithms and computational models.
Capabilities and Limitations of Humans
-
Capabilities:
- Machines recognize and process multiple languages to perform useful tasks based on given instructions.
-
Limitations:
- Human factors causing errors include physical, psychological, intellectual, environmental, and social factors.
Capabilities and Limitations of Computers
-
Capabilities:
- Self-directing with abilities to store, retrieve information, perform mathematical operations, and solve complex formulas with high precision.
-
Limitations:
- Computers can only execute pre-programmed tasks, cannot think independently, and cannot correct input data errors.
Branches of the Theory of Computation
- Encompasses three key areas:
- Automata Theory
- Computability Theory
- Complexity Theory
Automata Theory
- Founded by Alan Turing, recognized as the father of modern computer science.
- Studies abstract machines like Turing machines, even before physical computers existed.
Computer Architecture
- Model of Computation: Defines allowable operations and their costs.
- Algorithms: Step-by-step instructions for computer processing.
-
Types of Computer Architecture:
- Van Neumann Architecture: Single memory for both data and instructions.
- Harvard Architecture: Separate storage for data and instructions.
- Modified Harvard Architecture: Combination of Van Neumann and Harvard architectures.
- RISC and CISC: Different architectures for handling instructions.
Components of Computer Architecture
- CPU: Executes and manages data.
- Memory Hierarchy: Includes cache, RAM, and storage devices.
- I/O System: Facilitates communication between computers and external devices (e.g., keyboards, printers).
- Storage Architecture: Manages how data is stored and retrieved.
- Instruction Pipelining: Breaks down instruction execution into stages.
- Parallel Processing: Divides tasks into subtasks for concurrent execution.
Cloud Computing
- Enables access to applications and database resources via the Internet.
- Allows configuration and customization of applications from anywhere.
-
Deployment Models:
- Public Cloud: General access, less secure.
- Private Cloud: Limited to organizational access, more secure.
- Hybrid Cloud: Combination of public and private access.
- Community Cloud: Shared access among a group of organizations.
Cloud Service Models
- Infrastructure as a Service (IaaS): Offers control over infrastructure.
- Platform as a Service (PaaS): Provides a platform for building applications.
- Software as a Service (SaaS): Delivers complete software applications online.
Advantages & Disadvantages of Cloud Computing
- Provides flexibility and remote accessibility but may involve concerns about security and control depending on the model chosen.
