Study Notes
Turing Machine
- Invented by Alan Turing in 1936.
- Designed to simulate basic computer algorithms.
- Consists of a tape, head, and an internal state.
- Can process various symbols, such as 0, 1, and blank.
- Can read, write, and move the tape left or right.
Von Neumann Model
- Proposed by John Von Neumann around 1944-1945.
- Key idea: programs and data are logically the same and should be stored in memory.
- Divided computer hardware into three subsystems:
- Central Processing Unit (CPU)
- Main Memory
- Input/Output Subsystem
CPU (Central Processing Unit)
- The main processing component of a computer.
- Sometimes called a processor.
- Contains:
- Arithmetic Logic Unit (ALU): performs arithmetic and logical operations.
- Control Unit: manages the execution of instructions.
- Registers: fast storage locations used during processing.
- Today's CPUs often have multiple cores (dual-core, quad-core) for parallel processing.
- Measured by clock speed (MHz or GHz), indicating instructions per second.
- Other factors like architecture, memory, and bus speed affect overall performance.
Main Memory
- Collection of storage locations, each with a unique address.
- Data is transferred to and from memory in groups of bits called words.
- Important for exchanging information between the subsystems.
Data Storage
- Different data types (numbers, text, audio, image, video) are stored in computers as a uniform bit pattern.
- Numerical data is converted to binary representation.
- Integers can be stored using:
- Unsigned representation: for non-negative values.
- Sign-and-magnitude representation: for both positive and negative values.
- Two's complement representation: the standard method for storing integers today.
- Real numbers use floating-point representation.
- Text is stored using various encoding systems (ASCII, Unicode).
- Audio is stored using sampling, quantization, and encoding.
- Images are stored using:
- Raster graphics: pixels arranged in a grid.
- Vector graphics: mathematical descriptions of lines and shapes.
- Video is stored as a sequence of images (frames) over time.
Subsystem Interconnection
- Bus: an electronic path for data transfer.
- Bus width: number of wires in a bus, affecting data transfer capacity.
- Bus speed: speed of data transfer, measured by bandwidth.
- Wider buses and higher speeds provide greater throughput.
