Topic 1 - Digital devices (part 1)
Cards in this deck (16)
- 1Define peripheral devicesPeripheral devices are devices that can be connected to a computer. They can either be internal or external
- 2What are the 3 types of peripheral devices?- Input: Devices that provide data for the computer
- Output: Devices that display data from the computer
- Storage: Devices that can store data - 3Give 5 examples of output peripheral devices- Monitor
- Projector
- Printer (any)
- Speaker/microphone
- Headset - 4Give 5 examples of input devices- Scanner
- Mouse
- Keyboard
- Joystick
- Bar code reader - 5What is the differenece between memory and storageAlthough both of them store data they do it for different purposes and in different ways. Storage (secondary memory) are known as peripheral devices that store data for long terms. While memory (primary memory) store data for shorter terms.
- 6Provide 3 memory device (primary memrory) examples- ROM (Read Only Memory)
- RAM (Random Access Memory)
- Virtual memory - 7What is RAM?Random Access Memory stores data temporarily and it is volatile
- 8What is ROM?Read Only Memory stores data permenantly and is non-volatile
- 9What is virtual memory?A portion of the HHD designed to function as additional RAM to store data and not overload the RAM
- 10Give 5 examples of storage devices- Flash drive
- Memory card
- Magnetic Tape
- Any drive
- Disks - 11What does reading and writing data to storage devices mean?Writing data to a storage device is actually storing or saving it while reading data is retrieving it
- 12What are the 2 storage devices that read/write or store data?- Storage medium are the devices that actually store the data
- Storage devices are the devices that write to, read from or store to the media - 13State 3 characteristics of HHDs- High data access speeds
- Large storage capacity
- Store data of metal or glass rotating disks - 14State 3 characteristics of SSDs- *Solid* state drives have no moving parts
- More expensive
- Use flash memory and electronic circuits to store data
- Even higher data access speeds - 15State 3 characteristics of optical disk drives- Save data as patterns
- Data is read from them using light beams
- Portable - 16What are the 2 types of storage media?Recorable/write once (R)
Rewritable (R/W)
