ICT Fundamentals Assessment

ICT Fundamentals 131 Assessment

• The assessment consists of 4 questions, with a total of 100 marks.
• The assignment should be typed and printed, and a hard copy should be submitted.

CPU and Temperature

• A CPU temperature of 67 degrees Celsius is excessive and can cause overheating.
• Two devices that may need to be changed or upgraded to correct the temperature of the CPU are:
  • CPU cooler
  • Thermal paste

CPU Terminology

• CPU stands for Central Processing Unit.
• Two major brands of CPU in the market today are:
  • Intel
  • AMD

CPU Units

• A CPU has five major units responsible for data processing:
  • Control Unit
  • Arithmetic Logic Unit (ALU)
  • Registers
  • Cache
  • Bus

CPU Cache and RAM

• CPU cache is a small, fast memory that stores frequently accessed data.
• RAM (Random Access Memory) is a larger, slower memory that stores data temporarily.

IT Roles

• Three IT roles are:
  • Computer Technician
  • Network Administrator
  • Software Developer

Qualities of a Good Technician

• Three qualities of a good technician are:
  • Troubleshooting skills
  • Attention to detail
  • Communication skills

Printers

• Four types of printers are:
  • Inkjet
  • Laser
  • Dot Matrix
  • 3D

Printer Differences

• The differences between printers include:
  • Print quality
  • Speed
  • Cost
  • Technology used

Application Software and Operating System Software

• Application software is designed to perform specific tasks, such as word processing or gaming.
• Operating system software manages the computer's hardware and provides a platform for running applications.

Local and Network Printers

• A local printer is connected directly to a computer.
• A network printer is connected to a network and can be accessed by multiple devices.

Wireless Printer Connections

• Three ways to connect a wireless printer are:
  • Wi-Fi
  • Bluetooth
  • Infrared

Computer Components

• The green board in the picture is a motherboard.
• Eight internal components that are missing in the motherboard for making a complete internal computer are:
  • CPU
  • RAM
  • Power supply
  • Hard drive
  • Graphics card
  • Sound card
  • Network card
  • Optical drive

Purpose of Computer Components

• Each component has a specific purpose, such as:
  • CPU: executes instructions
  • RAM: temporarily stores data
  • Power supply: provides power to components
  • Hard drive: stores data
  • Graphics card: handles graphics processing
  • Sound card: handles audio processing
  • Network card: handles network connections
  • Optical drive: reads and writes optical discs

Firmware and Hardware

• Hardware refers to the physical components of a computer.
• Firmware is software that is permanently stored in read-only memory (ROM).

UEFI and BIOS

• UEFI (Unified Extensible Firmware Interface) is a firmware that provides a more modern and secure way of booting a computer.
• Two factors that make UEFI different from BIOS are:
  • UEFI uses a graphical interface, while BIOS uses a text-based interface.
  • UEFI provides better security features than BIOS.
