Technology Systems

In Technology Systems, I learned how computers and digital devices work.

This included learning about the main parts of a computer system and understanding how hardware and software work together.

I studied areas such as:

• Computer hardware
• Input devices
• Output devices
• Storage
• Processors
• Memory
• Operating systems
• Networks
• Computer performance

This unit improved my technical understanding of computers.

I learned about different computer hardware components.

These include:

• CPU
• RAM
• Storage devices
• Motherboard
• Graphics card
• Power supply
• Cooling systems

I learned that each component has a different purpose.

For example, the CPU processes instructions, RAM stores temporary data and storage devices keep files for longer periods.

I learned about input devices such as:

• Keyboard
• Mouse
• Microphone
• Camera
• Barcode reader
• Scanner

I also learned about output devices such as:

• Monitor
• Printer
• Speakers
• Projector

This helped me understand how users communicate with computer systems.

I learned about the role of an operating system.

An operating system manages the computer and allows hardware and software to work together.

Examples include:

• Windows
• macOS
• Linux
• Android
• iOS

I also learned about functions such as:

• File management
• Memory management
• User accounts
• Security
• Multitasking
• Device management

I learned that a device driver is software that allows the operating system to communicate with a specific hardware device.

For example, a printer or graphics card may need a driver so that the computer can use it correctly.

I learned the difference between RAM and permanent storage.

RAM is temporary memory that is used while programs are running.

Storage devices such as SSDs and hard drives keep files even after the computer is switched off.

I also learned about virtual memory and how it can be used when RAM becomes full.

I learned that computer performance can be affected by:

• CPU speed
• Number of processor cores
• Amount of RAM
• Storage type
• Graphics performance
• Cooling
• Software
• Number of programs running

This helped me understand why some computers are faster than others.
