| Input Devices | Devices that the consumer uses to input information into the computer. e.g Keyboards, Mice, Microphones, Scanners. |
| Output Devices | Devices that output information to the consumer. e.g Monitors, Speakers, Printers. |
| Non-Volatile Memory | Types of memory storage that holds data and information after power is turned off. e.g Solid State Drives, Magnetic Disks, ROM, CD-ROM. |
| Volatile Memory | Type of memory storage that loses all data it is holding after the power is turned off. e.g RAM, Cache. |
| Secondary Storage | Secondary Storage is anything that stores data permanently. It can also be external. e.g Magnetic Storage, Optical Storage. |
| Magnetic Storage | It's a magnetic disk that uses moving read and write heads that contain electromagnets. These create a magnetic charge for 0 (off) or 1 (on). |
| Advantages of Magnetic Storage | > Very large data capacity > Stores and retrieves data faster than optical drives > Non-Volatile > Cheaper than other methods > Can be easily replaced or upgraded |
| Disadvantages of Magnetic Storage | > Hard drives use moving parts and will fail > Crashes can damage surface of the disk, leads to loss of data > Use a large amount of power compared to other storages types. > Can be noisy |
| RAM | (Random Access Memory) is an example of Volatile memory. It works as a bridge between the hard drive and the processor to speed up the processing process. Using RAM is faster |
| CPU | (Central Processing Unit) Often referred to as the computer's brain, this processes all information and performs functions in the computer. |
| Order the way the memory flows from the disk storage to the CPU | Storage > Virtual Memory > RAM > Cache > CPU |
