ABSTRACT This paper aims to provide an overview on the emergence and development of the technology acceptance model (TAM) by Fred Davis by summarizing its evolution, its key applications, extensions, limitations and criticisms addressed to him. This model is an example of how users accept and use technology, for which researchers have different opinions about its theoretical assumptions and practical effectiveness. This article presents the theory and the technology acceptance models that have been developed based on this theory (TAM2, TAM3 and UTAUT). The focus is predominantly on constructs models and hypotheses to be tested in order to validate their use in different contexts.
Keywords: technology, models and theories, using the system.

1. Introduction
Theories and models of acceptance of new technology helps create an appropriate theoretical framework and experimentation that can demonstrate appropriate use of technology and systems. The literature contains several studies on the application of technology acceptance model, including synthesis and meta-analysis. These studies mainly analyze users' perceptions of the determinants of technology acceptance and causal relationships between these factors and behavioral intentions to use. In Romania among those who used the technology acceptance models include Balog and Pribeanu (2009, 2010) and Balog (2012, 2013).
In this article is presented and analyzed theory of technology acceptance (TAM) and models that have been developed based on this theory. Therefore, the first section describes the technology acceptance model (TAM), section 2 briefly describes how they were developed and validated perceived usefulness and perceived ease of use of the TAM model. In section 3 will be presented developments and major extensions TAM model proposed in the original TAM model. The paper concludes with limitations and criticisms of the technology acceptance model (TAM).
2. Technology acceptance model (TAM)
Technology acceptance model (TAM) is an information systems theory developed in order to make predictions about technology acceptance. This model suggests that when users are presented with a new technology, a number of factors influence their decision about how and when they will use. TAM is based on the causal relationship belief - attitude - intention - behavior within the theory of reasoned action (TRA).
The starting point for the development of the technology acceptance model (TAM) by Fred Davis was the...
