TAM Model (Technology Acceptance Model). Technology Term needs to be defined according to the researcher opinion. Or to agree with some other definition that has been stated in previous research.

The Technology Acceptance Model was developed by (Davis et al., 1989), most utilized in studying the technology acceptance model (Al-Gahtani, 2001) . The model has been tested widely with varied sample size and situation and proved to be valid and reliable model deliberating new technology implementation and its use (Davis and Venkatesh, 1996). Many extensions to original TAM have been proposed (Lu et al., 2003; Venkatesh et al., 2002; Venkatesh and Davis, 2000).

The TAM has also been shown to work well with other scales to improve measurment. It is often useful to add a scale from the literature that is more specific to the type of technology or use you have in mind.
