Assume the following rules of associativity and precedence for expressions:

Precedence Highest *, /, not +, –, &, mod – (unary) =, /=, < , <=, >=, > and Lowest or, xor

Associativity Left to right

Show the order of evaluation of the following expressions by parenthesizing all subexpressions and placing a superscript on the right parenthesis to indicate order.

For example, for the expression a + b * c + d

the order of evaluation would be represented as ((a + (b * c)^1 )^2 + d)^3

Draw parse trees for the following expressions in exercise 9: a., d., and f.

a. a * b - 1 + c
d. -a or c = d
f. -a + b

The technology acceptance model (tam) is a two-factor model that describes user acceptance of new or replacement technology solutions (davis, 1989). this evaluation model has withstood the test of time and is widely used. the model is based upon perceptions and beliefs of individuals and measures two types of factors: (a) perceived ease of use and (b) perceived usefulness. prepare an analysis (briefing paper) (5 to 7 strong paragraphs) in which you explain how cybersecurity researchers could use the tam model to explore the factors which affect employee acceptance of biometrics used for access to facilities and/or computing systems. what research questions might they ask? what measurements would be needed? post your briefing paper as a reply to this topic. remember to cite your sources (3 minimum) and include a reference list at the end of your posting.
