Study Notes
Computer Systems
- A system is a set of components working together to achieve specific objectives, providing a service.
Computers
- Computers are electronic machines that automatically compute problems at high speeds.
- They are not just laptops and desktops: Computers include tablets, smartphones, and even embedded systems within cars.
- Computers help us process and analyze large volumes of data, automate tasks, communicate globally, and innovate.
- Key uses of computers include:
- Data processing and analysis for decision-making.
- Automating tasks for increased efficiency.
- Communication and connectivity using various tools.
- Innovation and creation of multimedia content.
- Research and access to vast amounts of information.
- Revolutionizing education with online learning resources.
- Entertainment, healthcare, finance, e-commerce, weather prediction, space exploration, agriculture, and social interaction.
- The development of electronics is key to the evolution of computers.
- Moore's Law: The number of transistors on an integrated circuit (IC) doubles roughly every two years.
- Problems that can be solved by a computer are called computable problems.
- Decidability relates to solving decision problems, which are problems with a yes/no answer.
- Some problems are uncomputable or undecidable because they cannot be solved by computers.
