Q4: ... is a malicious technique of tricking a Web user into clicking on something different from what the user perceives they are clicking on, thus potentially revealing confidential information or taking control of their computer?
Answer: Clickjacking
Explanation: Clickjacking is a malicious technique of tricking web user into revealing confedential information while clicking on seemingly innocrous web pages. A clickjack takes the form of embedered code or a script that can use without the user's knowledge by clicking on a button that appear to perform another function term clicking was coined by jeremiah grossman and robert hausen in 2008.

Q9: The period of second generation computer was
1.1946-1958
2.1940-1960
3.1959-1964
4.1965-1975
Ans.(3) 1959-1964
Explanation: By 1948 the invention of transistor greatly changed the computer development. the transistor replaced the large cumbersome vaccum tube in television, radios and computer. As a result size of electronic machinary has been shrinking existence. from 1955 onward transister replace vaccum tubes in a computer design, giving rise to the second "generation" of computer.
