The term is often written without a hyphen as "open source software".

Il : The 'right to use' a piece of software is termed as copyright. Which of the above statement(s) islare CORRECT? (1) Both I and II (2) Neither I nor II (3) II only (4) I only Notes: Information technology (IT) is the application of computers to store, study, retrieve, transmit, and manipulate data, or information, often in the context of a business or other enterprise. IT is considered a subset of information and communications technology (ICT) Copyright is a legal right created by the law of a country that grants the author of an original work exclusive right for its use and distribution.

(1) Secondary Storage; Main Memory (RAM); Cache Memory; CPU Registers (2) CPU Registers; Cache Memory; Secondary Storage; Main Memory (RAM) (3) CPU Registers; Cache Memory; Main Memory (RAM); Secondary Storage (4) Cache Memory; CPU Registers; Main Memory (RAM); Secondary Storage Answer 3 3. Which of the following is a characteristic of Web2.0 applications? (1) Multiple users schedule their time to use Web2.0 applications one by one. (2) Web2.0 applications are focused on the ability for people to collaborate and share information online.

6 Which of the following statement(s) islare TRUE? S1: The decimal number 11 is larger than the hexadecimal number 11. S2: In the binary number 1110.101, the fractional part has the decimal value as 0.625 (1) S1 only (2) S2 only (3) Both S1 and S2 (4) Neither S1 nor S2 Answer: 2 Notes To convert Hexadecimal number to Decimal number, multiply every digit with 16 power of digit location. Then, sum all the multipliers. Decimal representation of hexadecimal number 11 = 1x161+1x160 = 16+1 = 17 To convert decimal fraction to binary, begin with the decimal fraction and multiply by 2 Because .625 x 2 1.25, the first binary digit to the right of the point is a 1. Because .25 x 2 0.50, the second binary digit to the right of the point is a 0. Because .50 x 2 = 1.00, the third binary digit to the right of the point is a 1. In fact, we do not need to multiply the fraction again, because we had 0 as the fractional part of our result there. Hence the representation of .625 = .101 (base 2).
