What are specifications of digital devices and their impact upon usability?
Specifications are a detailed description of the design and capabilities of a device; usability is the degree to which a digital device is easy and efficient for users.
What are characteristics of development trends in emerging mobile devices?
Technological convergence – bringing related technologies together in a single device; examples include smartphones, wearables, and drones.
How is the suitability of emerging mobile devices determined to meet client (user) needs?
It depends on what the client wants and needs the device for.
How is the usability of digital devices determined for specified client requirements?
It depends on what the client wants and needs the device for.
Function of the CPU
The CPU is the brain of the computer; it performs processing and calculations, executes instructions stored in memory, performs arithmetic and logical operations, and manages overall computer operations.
Function of the Motherboard
The motherboard is the main circuit board; it connects all components allowing communication, houses CPU socket, RAM slots, expansion slots, and peripheral connectors.
Function of the Power Supply
The power supply converts AC power to DC power and provides necessary voltage/current to all computer components.
Function of the Display
The display (monitor) is an output device that visually presents information processed by the computer, converting digital signals into a visual format for user interaction.
Function of RAM
RAM is volatile memory that temporarily stores data and instructions the CPU needs quickly, allowing faster access than storage devices.
Function of GPU
The GPU is a specialized processor for rendering graphics and images, offloading work from the CPU for faster, efficient visual data processing.
HDD
Hard disk drive
- stores data permanently using magnetic storage
- contains spinning platters with magnetic coating
- moving mechanical arm
- used for long-term storage
SSD
Solid State Drive
- stores data permanently using flash memory chips
- no moving parts
Outdated software on new hardware
- software feels slow
- older software might run too fast, causing instability, errors or making software unusable
- leads to system crashes or errors
- security vulnerabilities could be exploited
Modern software on outdated hardware
- long loading times and very low frame rates
- limited resolutions and a poor visual experience
