2 study sections · pause after each one and recall the key ideaComputers come in many sizes and power classes, each suited to a purpose — from tiny embedded controllers inside appliances to supercomputers that model the weather.
Key points- Supercomputers: fastest, used for research, simulations, weather forecasting.
- Mainframes: process huge volumes of transactions for banks and governments.
- Servers: provide services (files, web pages, email) to other computers on a network.
- Personal computers: desktops and laptops for general use.
- Mobile devices: smartphones and tablets — portable, sensor-rich, always connected.
- Embedded/dedicated devices: built into cars, washing machines and TVs to do one job.
- Server — a computer that provides services to client computers.
- Embedded computer — a computer built into another device with a fixed function.
EXAM TIP
match the computer type to a scenario ("a bank processing millions of debit orders overnight" → mainframe).
