Types of Computing Overview

Definition of Computing

• The act of using computer systems to perform calculations, process data, and solve problems.
• Encompasses both hardware (physical components) and software (programs and applications).

Types of Computing

1. Personal Computing

   • Designed for individual use.
   • Involves PCs, laptops, and tablets.

2. Mobile Computing

   • Utilizes portable devices such as smartphones and tablets.
   • Focuses on mobility and wireless communication.

3. Cloud Computing

   • Provides on-demand access to shared computing resources over the internet.
   • Types include Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

4. High-Performance Computing (HPC)

   • Utilizes supercomputers and clusters for complex computations.
   • Common in research, simulations, and large data analysis.

5. Distributed Computing

   • Systems that work together over a network to achieve a common goal.
   • Includes grid computing and peer-to-peer networks.

Key Concepts

• Algorithms: A set of rules or steps used for calculations and problem-solving.
