Study Notes
Computer Basics
- A computer can perform both computations and logical decisions.
- Common components of computer hardware include keyboard, mouse, and CD-ROM; compilers are not hardware.
- The Arithmetic and Logic Unit (ALU) is responsible for arithmetic calculations and logic decisions.
Programming Languages
- C is considered a high-level programming language, developed by Dennis Ritchie.
- Java, a versatile language, is primarily used for large-scale enterprise applications.
- Object-oriented programming promotes reusable software components.
Operating Systems and Functions
- Operating systems manage transitions between jobs and oversee computer resources.
- Batch processing systems do not perform multiple tasks simultaneously; they process jobs in batches.
Programming Concepts
- Multitasking refers to running multiple activities in parallel within a program.
- The C Standard Library provides pre-written functions for common programming tasks.
- Structured programming encourages clear and modular coding.
Computer Architecture
- CPU (Central Processing Unit) supervises and coordinates other computer sections.
- Secondary storage units, such as hard drives, store data long-term.
Internet and Networking
- The World Wide Web is primarily used to view multimedia documents.
- Packet switching allows multiple users to send and receive data concurrently on the Internet without centralized control.
True/False Facts
- A computer’s primary role is to perform computations and logical decisions (True).
- Secondary storage is slower than primary memory (False).
- The C programming language is designed to be hardware-independent (False).
Fill in the Blanks Concepts
- Computer processes data via programs, using an input unit to gather data from peripherals.
- Machine languages consist of strings of numbers providing specific instructions.
- Functions in C perform specific tasks within a program.
- Objects in object-oriented programming represent reusable software components.
Trends in Computing
- Hardware capacity doubles approximately every year or two, indicating rapid technological advancements.
- Distributed computing refers to computing spread across multiple networks.
Additional Notes
- Java was created to support dynamic and interactive web content.
- The ALU is integral for performing arithmetic calculations and logical decisions within a computer.
