Data Types

Data Types

1. Analogue Data

   • Is the use of values that change very smoothly
     • It is used for reading values that move constantly for example in an analogue clock the seconds hands shows the time smoothly or in the sound waves
       • some other examples are microphones, headphones,loud speaker,and sensors this are analogue devices but they use analogue data.

2. Digital Data

   • This data jumps from one value to the next in a step by step sequence, also it is not continuous or smooth
     • An example could be a digital clock because we can see clearly the step by step it pass for changing seconds
       • Also the computers/ laptops/ ipads, mobile phones, MP3 player and the digital camera are digital devices that why they use digital data

3. Binary

   • All computer data is a number known as binary digit
     • It is represented by the numbers 1and 0
       • The differents combinations of 1 and 0 are used to represented all the differents kinds of data processed and store by a digital devices

4. ADC

   • It is the convert of analogue data make by an analogue device to digital data so a computer can use it

5. DAC

   • Is the convert of digital data to analogue data so the data pass from numbers to sound waves
