Internal Components of a Computer Study Guide

Internal Computer Components Overview

  • Internal components of a computer are categorized into four primary groups:
    • CPU - Central Process Unit (unidad Central de Procesamiento): The primary execution and processing engine.
    • Tarjetas: Expansion boards and main connection circuitry.
    • Memorias: High-speed memory chips located on the motherboard.
    • Almacenamiento: Data storage systems.

CPU - Central Process Unit (Unidad Central de Procesamiento)

  • General Functions and Classification:
    • Known as the brain of the computer (Cerebro de la computadora).
    • Functions as the central location where all data is processed.
  • Core Structural Components:
    • Composed of two fundamental internal units:
    • Unidad de control (Control Unit)
    • Unidad aritmética y lógica (Arithmetic Logic Unit)
  • Unidad de Control (Control Unit):
    • Controls all hardware and system resources of the computer.
    • Directs the flow of data through the CPU, as well as to and from other connected devices.
    • Contains the instructions required to execute computer operations and tasks.
  • Unidad Aritmética y Lógica (Arithmetic Logic Unit):
    • Handles data that is represented and stored in the computer as numbers.
    • Performs data processing which largely consists of comparing numbers and performing mathematical operations.

System Cards and Motherboard (Tarjetas)

  • Purpose of System Cards:
    • Designed to expand, control, and enhance the overall operation and performance of the computer.
  • Tarjeta Madre (Motherboard):
    • Represents the main board (placa principal) of the computer system.
    • Contains all printed circuits (circuitos impresos) of the machine.
    • Connects all other internal elements.
    • Enables direct communication and connection between its integrated elements and all other external or internal components.

System Memory Architecture (Memorias)

  • General Memory Characteristics:
    • Consists of microchip sets physically located on the motherboard (chips ubicados en la tarjeta madre).
    • Features high-speed read and write capabilities for active programs and data while in use.
  • Memoria ROM (Read Only Memory):
    • Classified strictly as read-only memory (Memoria de lectura solamente).
    • Stores a pre-programmed set of instructions that allows the computer to boot up and initialize correctly (iniciar correctamente).
  • Memoria RAM (Random Access Memory):
    • Main function is to host programs and data while they are actively being used (alojar programas y datos mientras se están utilizando).
    • The term "random" (aleatorio) means any memory address can be accessed directly at any moment, resulting in high operational speed.
    • Without random access capability, computer processing speed would be severely degraded.
  • Memoria Flash:
    • A specialized type of permanent memory.
    • Integrated into portable digital devices for media and data storage.
    • Specifically utilized in:
    • Digital cameras (cámaras)
    • Portable media players (reproductores portátiles)
    • USB flash drives (USB)
    • Video game consoles (consolas de juegos)

Data Storage (Almacenamiento)

  • Primary Purpose:
    • Storage components are tasked with saving and maintaining the data produced during the active operation and functioning of the system (guardar los datos que se producen durante el funcionamiento del equipo).
