Study Notes
Architecture of Computers
- Architecture of computers is a branch of computer science that focuses on the design and organization of computers. It encompasses hardware, software, and their interaction.
- Computers consist of various fundamental units, including the Central Processing Unit (CPU), memory, and input/output (I/O) units.
Central Processing Unit (CPU)
- The CPU is the core of the computer, responsible for executing instructions.
- It comprises an Arithmetic Logic Unit (ALU) for mathematical and logical operations, and a Control Unit (CU) to manage the instruction flow.
Memory
- Memory stores both instructions and data temporarily during program execution.
- Different types of memory exist, with some used for faster access by the CPU.
- Memory can be described as being "unified" where instructions and data are stored in the same space, in contrast to the "separated" approach where instructions are stored in one part of the memory and data are stored in another.
Input/Output (I/O) Units
- I/O units enable the computer to interact with the outside world.
- Examples include keyboards, screens, and disk drives.
Von Neumann Architecture
- A significant design for computer architecture.
- Data and instructions share the same memory space, a key feature of this architecture.
Harvard Architecture
- An alternative computer architecture.
- Data and instructions are stored in separate memory units.
- It permits concurrent access to instructions and data, potentially leading to improved performance for certain applications.
Difference between Von Neumann and Harvard Architecture
- Von Neumann architecture has a unified memory, while Harvard architecture has separate memory for instructions and data.
- Von Neumann's architecture is less complex, but the Harvard architecture allows for concurrent access to instructions and data, which can improve performance under certain circumstances.
