Boolean Logic Quiz: Test Your Computer Technology Knowledge

Study Notes

Generations of Computers

First generation (1940-1956): Vacuum tubes used for circuitry and magnetic drums for memory.
Second generation (1956-1963): Transistors replaced vacuum tubes, leading to smaller, faster, and cheaper computers.
Third generation (1964-1971): Integrated circuits miniaturized circuits, improving performance and energy efficiency.
Fourth generation (1971-present): Microprocessors emerged, making computers more accessible to the public and enabling personal computing.
Fifth generation (Present and beyond): Focus on artificial intelligence and machine learning, incorporating advanced computing techniques.

Basic Operations in Boolean Algebra

AND operation: Results true only if both operands are true.
OR operation: Results true if at least one operand is true.
NOT operation: Inverts the value of the operand (true becomes false and vice versa).
XOR operation: Results true if exactly one operand is true.
NAND and NOR operations: Negations of AND and OR, respectively, providing additional logical functions.

Data Types in Instruction Set Architecture (ISA)

Integer: Whole numbers, typically signed or unsigned, of various sizes (e.g., 32-bit, 64-bit).
Floating-point: Decimals represented in a scientific notation format, allowing for fractional values.
Characters: Single characters represented using encoding schemes like ASCII or Unicode.
Boolean: Represents true or false values for control logic.
Pointers: Memory addresses referencing data locations.

Types of Addresses in Instruction Set Architecture (ISA)

Immediate Addressing: Operands specified directly within the instruction.
Direct Addressing: Address of the operand specified directly as part of the instruction.
Indirect Addressing: Address refers to another memory location to find the operand.
Register Addressing: Operand stored in a CPU register specified in the instruction.
Indexed Addressing: Base address offset by a specific value for accessing data structures.

Components of the Instruction Set in Instruction Set Architecture (ISA)

Data types: Define the format of data the processor can handle.
Instruction formats: Specifies how instructions are structured, including opcode and operands.
Addressing modes: Defines ways to access operands stored in memory or registers.
Control instructions: Manage the flow of execution (e.g., jumps and branches).

Different States in Instruction Set Architecture (ISA)

User Mode: Limited access to system resources, protecting system stability.
Supervisor Mode: Also known as kernel mode, providing full access to all system resources.
Interrupt Mode: Handles interrupts from hardware to manage events requiring immediate attention.

Two Types of Operands in Computer Hardware

Register Operands: Located within CPU registers.
Memory Operands: Located in system memory, requiring addressing modes for access.

Two Main Categories of Numbers

Whole numbers: Non-fractional numbers, including both positive and negative integers.
Real numbers: Includes both rational and irrational numbers, typically represented as floating-point values.

Four Supporting Procedures in Computer Hardware

Fetch: Retrieves instructions from memory for execution.
Decode: Interprets the fetched instructions to understand the required operations.
Execute: Performs the specified operations using the necessary data.
Write-back: Saves the results of the executed instructions back to memory or registers.

Four Components Involved in Translating and Starting a Program

Compiler: Translates high-level code into machine code.
Linker: Combines different code modules into a single executable.
Loader: Loads the executable into memory for execution.
Operating system: Manages resources and coordinates the execution of programs.

Three Special Operating Modes

Normal Mode: Standard operating mode for typical applications.
Protected Mode: Enhances protection by isolating processes and managing memory access.
Real Mode: Directly accesses hardware without protection features, primarily used in legacy systems.

Three Types of Context Switch

User-to-Kernel switch: Transition from a user process to the operating system for handling system calls.
Kernel-to-User switch: Transition back to a user process after the completion of a system call.
Inter-process switch: Switching between different processes running in the operating system.
