1. Multifunctional devices

   • Could also be known as All In One devices (AIO)

2. Differences between buying a desktop and a laptop

   • Desktop is not portable but has more storage, faster and better specs and is customisable and has a larger screen.
   • Laptops are portable but they have less storage, slower and worse specs, they are hard to customise and have a smaller screen

3. Internal PC components

   • Motherboard - the backbone of the computer that brings everything together
   • Central Processing unit - Acts as the control centre
   • Random Access Memory - Computers short term memory
   • Hard disk drive - used as storage with moving parts so it is slower
   • Solid state drive - used as quicker storage then HDD because of no moving parts
   • Power supply unit - they convert power for the computer to use

4. Mainframes and supercomputers

   • Mainframes - Mainframes go through 1000s of transactions per second, for instance, Bank Transactions
   • Supercomputers - Supercomputers use lots of power to calculate a single calculation, for instance, scientific calculations

5. System-on-chip - Usually contain internal components like CPU, RAM and a battery. Because of these being so close together the processing speed is increased because the signal has less space to travel.

6. Peer-to-peer network - a group of computers that are linked to gather with equal permissions and responsibilities.

7. Client/server network - where computers are linked together through a central server.
