Understanding ICT Systems: Internal Hardware

This video introduces ICT systems, focusing on hardware components. It distinguishes between internal and external hardware, emphasizing the critical role of internal components like the CPU, RAM, and storage devices. The video explains the CPU's function as a central processing unit, detailing its processes of fetching, decoding, and executing instructions. It compares HDDs and SSDs, highlighting their differences in speed, reliability, and usage. Finally, the video discusses RAM's role in temporary data storage and its importance in modern computing.

What are the four key components of an ICT system?

• CPU, RAM, HDD, SSD

• Monitor, Keyboard, Mouse, Printer

• Hardware, Software, Data, Users

• Input, Output, Processing, Storage

Which of the following is NOT considered internal hardware?

• Motherboard

• Monitor

• RAM

• CPU

What is the primary function of the CPU in a computer system?

• Store data permanently

• Execute instructions and process data

• Provide power to the system

• Connect external devices

Which type of storage retains data even when the power is turned off?

• HDD

• ROM

• RAM

• Cache

What is a key advantage of SSDs over HDDs?

• Higher data transfer rates

• Lower cost

• Larger physical size

• More moving parts

How does RAM differ from ROM?

• RAM is slower than ROM

• RAM is used for permanent storage, ROM is temporary

• RAM is rewritable, ROM is not

• RAM is non-volatile, ROM is volatile

What is the primary role of RAM in a computer system?

• Provide temporary storage for active processes

• Store data permanently

• Connect external devices

• Manage power supply

In the context of gaming, what role does RAM play?

• Provides temporary storage for game operations

• Processes graphics

• Stores game data permanently

• Connects to the internet

What happens to data stored in RAM when the power is turned off?

• It is saved to the hard drive

• It is permanently deleted

• It remains intact

• It is transferred to ROM

Why is it important to save your work frequently when using applications like Microsoft Word?

• To reduce memory usage

• To ensure data is stored in RAM

• To prevent data loss in case of power failure

• To increase processing speed
