Study Notes

Computer Storage

Primary Storage: Temporary storage for data currently in use; allows quick access to the CPU.
Secondary Storage: Permanent storage that retains data even when the computer is off; slower access compared to primary storage but essential for large data storage.

Virtual Memory (VM)

Definition of VM: Uses a portion of secondary storage to extend the available memory when RAM is full.
Purpose: Provides the illusion of additional RAM, enabling more applications to run simultaneously.

Local Area Network (LAN)

LAN Characteristics: Covers a small geographical area, typically within a single building, using a star topology for easy management and failure isolation.
Network Protocol: TCP/IP operates using a layered architecture, improving organization and standardization.

Pseudocode Algorithms

Exponential Output: To output 12 squared, use print(12 ** 2).
Odd or Even Check: Use modulo operator to check parity; if number % 2 == 0 then.
Measurement Difference: Use subtraction to find difference; difference = measurement1 - measurement2.

Computer Components

Memory Address Register (MAR): Stores a single address of data to be accessed from memory.
Memory Data Register (MDR): Stores data that is currently being transferred to or from the memory.
Cache: Holds frequently used instructions and data for quick access by the CPU.
Program Counter: Keeps track of the address of the next instruction to be executed.
Random Access Memory (RAM): Stores all currently running data and instructions for the CPU.

Registers

Example of Additional Register: Program Status Register (PSR); it indicates the status of the program or the operation being performed.

True/False Statements about VM

True Statements:
- A section of primary storage can be partitioned to act as virtual memory.
- Virtual Memory is needed when RAM is full or nearly full.
False Statements:
- Data from ROM is not transferred into VM (rather, VM acts as an extension of RAM).
- Data from VM is transferred back to RAM or accessed directly, not back to secondary storage when needed.
