Study Notes
Introduction to Computers
- A computer is an electronic device that takes input, processes it according to stored instructions, and provides output.
- Basic functions of a computer include Input (I/P), Process, and Output (O/P).
- Key components include Input Devices (peripherals), the Central Processing Unit (CPU), and Output Devices.
System Components
- Input Devices: Keyboard, Mouse, Track Pad, Scanner, Microphone.
- Processing Unit: Central Processing Unit (CPU) with Control Unit (CU) and Arithmetic Logic Unit (ALU).
- Output Devices: Monitor, Printer, Projector, Headphones/Speakers.
- Internal components include the motherboard, BIOS, power supply, cooling systems, hard drive configurations, and internal memory (RAM, ROM, cache).
Computer Architectures
-
Von Neumann Architecture:
- A foundational model for computer structure; uses stored-program concept with instruction and data in the same memory.
- Fetch execute cycle consists of a series of stages: Memory Address Register (MAR) fetches instructions, and decoded instructions are executed by the CPU.
-
Non-Uniform Memory Access (NUMA):
- Developed in the 1990s for multiprocessor systems; memory access speed varies based on proximity to the processor.
-
Quantum Computing Architecture:
- Based on qubits; offers exponential computational power and potential applications in cryptography and complex problem-solving.
-
Parallel Computing Architecture:
- Involves multiple processors working simultaneously, prevalent in supercomputers.
-
Distributed Computing Architecture:
- Spreads computations across multiple geographic nodes; commonly used in cloud and grid computing.
-
System-on-a-Chip (SoC) Architecture:
- Integrates all components into a single chip; widely used in mobile devices.
Evolution of Computers
-
First Generation (1940-1956): Utilized vacuum tubes; input via punched cards; examples include ENIAC, which had limited storage and required manual program configuration.
-
Second Generation (1956-1963): Introduced transistors; smaller size and reduced computing time compared to the first generation.
-
Third Generation (1963-1971): Used Integrated Circuit technology; smaller size, less power consumption, and easier commercial use.
-
Fourth Generation (1972-2010): Based on microprocessor technology; resulted in drastically smaller and portable machines with improved reliability and cost-effectiveness.
-
Fifth Generation (2010-present): Includes advancements like artificial intelligence and quantum computation; characterized by high capabilities and multitasking ability.
