Solutions
S1. Ans.(d)
Sol. Input, output and processing devices are basic units of a Computer System.
S2. Ans.(c)
Sol. Abacus used ‘set of beads’ to represent the unit of data
S3. Ans.(d)
Sol. Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. The system can then be said to feed back into itself.
S4. Ans.(d)
Sol. The continued improvement in fourth generation allowed the networking of computers for the sharing of data. Local Area Networks(LAN) and Wide Area Network(WAN), were potential benefits, in that they could be implemented in corporations and everybody could share data over it. Then the internet and World Wide Web appeared on the computer scene and fomented the Hi-Tech revolution of 90's.
S5. Ans.(d)
Sol. EBCDIC Code is a binary code for alphabetic and numeric characters that IBM developed for its larger operating systems. It is the code for text files that is used in IBM's OS/390 operating system for its S/390 servers and that thousands of corporations use for their legacy applications and databases.
S6. Ans.(c)
Sol. A pixel is the smallest portion of an image or display that a computer is capable of printing or displaying.
S7. Ans.(a)
Sol. Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which are data structures that contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. Java is an object oriented programing language.
S8. Ans.(d)
Sol. A computer program is a collection of instructions that performs a specific task when executed by a computer. A computer requires programs to function, and typically executes the program's instructions in a central processing unit.
S9. Ans.(a)
Sol. ADP is a data file format created by Microsoft Access.
S10. Ans.(a)
Sol. Ada Lovelace found a language of her own and wrote the world’s first computer program, long before the advent of the first computer.
S11. Ans.(c)
Sol. A software bug is an error, flaw, failure or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways.
S12. Ans.(c)
Sol. A binary number consist of combinations of only '0' and '1'.
S13. Ans.(b)
Sol. In computer architecture, a bus is a communication system that transfers data between components inside a computer, or between computers. Early computer buses were parallel electrical wires with multiple connections, but the term is now used for any physical arrangement that provides the same logical function as a parallel electrical bus. Modern computer buses can use both parallel and bit serial connections.
S14. Ans.(c)
Sol. Disk Defragmenter is a utility in Microsoft Windows designed to increase access speed by rearranging files stored on a disk to occupy contiguous storage locations, a technique called defragmentation.
S15. Ans.(d)
Sol. Drop Down menu is also called drop down list or pull down list.
