Introduction to Personal Computer Hardware Lecture

Overview

• Module 1 focuses on an introduction to personal computer hardware.
• The lecture includes a practical demonstration with an actual PC.
• The focus is on understanding the components inside the computer, including input and output devices.

Computer Case and Components

• Cases can have side panels held by screws or push tabs.
• Older models may include components like disc drives, which are rare in new computers.
• Cases can be made of glass, metal, or hard plastic, often depending on aesthetics and cost.

Power Supply

• Essential for computer operation; different specifications based on components.
• Types of power supplies: AT, ATX (common), and EPS (for high-end use like gaming).
• Power supplies have various connectors for different components.

Internal Components

• Motherboard: The main circuit board, likened to the nervous system. Includes:
  • CPU (Central Processing Unit): The brain of the computer.
  • RAM (Random Access Memory): Allows for multitasking and efficient performance.
  • Expansion slots: For video cards, sound cards, etc.
• CPU: Delicate component that requires careful installation.
• Cooling System: Essential for CPU, includes fans or water cooling. Thermal paste recommended.

Hard Drives

• HDD (Hard Disk Drive): Traditional drives with metal platters.
• SSD (Solid State Drive): Faster, flash-based storage used for operating systems.
• Newer drives like SSD are more common in modern builds.

Connectors and Ports

• SATA: Used for connecting hard drives and optical drives.
• PCIe: For high-speed components like GPUs.
• USB and Ethernet Ports: Common connectivity options.

Peripheral Devices

• Input Devices: Keyboards, mice, and newer tech like touchscreens and styluses.
• Output Devices: Monitors, projectors, and printers.

Practical Application

• The course includes "check your understanding" quizzes and reading assignments.
• Emphasis on hands-on learning by assembling and disassembling components.
• Importance of understanding power and cooling requirements for different builds.

Exam and Certification Notes

• Information will be relevant for the CompTIA certification test, focusing on hardware components.
• Practice exams will be available to help prepare for certification exams.

Administrative Notes

• Course modules and materials are available on a platform managed by Cisco.
• Exams and quizzes are part of the learning path but aren't immediately due.

Additional Resources

• Check Canvas and the associated online platform for more resources and the recording of this session.
• Instructor open for questions via email for further clarification and help.
