1. D. wait, signal
Semaphore S is an integer variable that is accessed through standard atomic operations i.e. wait() and signal().
2. a) banker’s algorithm
3. b) starvation
4. b) thread
In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system.
5. c) Interleaving
6. a) Redundant Array of Independent Disks
7. b) Pipelining
8. d) All of these
9. b) Cache
10. a) serial communication transmission of data
RS-232, Recommended Standard 232 is a standard introduced in 1960 for serial communication transmission of data.
11. c) Direct Memory Access
12. b) Three
A CD made of three layers. Most of a CD is made from a tough, brittle plastic called polycarbonate. Sandwiched in the middle there is a thin layer of aluminum. Finally, on top of the aluminum, is a protective layer of plastic and lacquer.
13. b) Saturation
Emitter-coupled logic (ECL) is the fastest of all logic families and therefore is used in
applications where very high speed is essential. High speeds have become possible in
ECL because the transistors are used in difference amplifier configuration, in which
they are never driven into saturation and thereby the storage time is eliminated.
14 b) 230 bytes
15. d) Dn =log2n + 1
16. a) internal nodes on extended tree
17. c) Quick sort
18. a) Arrays
19. a)O(n log(n))
20. c)Time and space
21. c) end
printf statement will print end because string is terminated at “\0” and in array after d, we have null character.
22. d) Header file
23. b) Extern
Keyword extern is used for declaring extern variables in c. This modifier is used with all data types like int, float, double, array, pointer, structure, function etc. It is default storage class of all global variables as well all functions. The extern keyword means "declare without defining".
24. a) : :
Scope resolution operator
25.a) java.lang
The Package java.lang. The java.lang package contains classes that are fundamental to the design of the Java language. The most important classes are Object , which is the root of the class hierarchy, and Class , instances of which represent classes at run time.

26. b)Global variables creates collisions in namespace.
27. c) 42 -43
Explanation: Unary not operator, ~, inverts all of the bits of its operand. 42 in binary is 00101010 in using ~ operator on var1 and assigning it to var2 we get inverted value of 42 i:e 11010101 which is -43 in decimal.
28. d) Number
Number is an abstract class containing subclasses Double, Float, Byte, Short, Integer and Long.
29. a) Public
Access specifier of interface is either public or no specifier. When no access specifier is used then default access specifier is used due to which interface is available only to other members of the package in which it is declared, when declared public it can be used by any code.
30. a) equals()
The equals() method compares two objects for equality and returns true if they are equal. The equals() method provided in the Object class uses the identity operator ( == ) to determine whether two objects are equal.
31. c) data members
32. a) NMI
Hardware interrupt is caused by any peripheral device by sending a signal through a specified pin to the microprocessor. The 8086 has two hardware interrupt pins, i.e. NMI and INTR. NMI is a non-maskable interrupt and INTR is a maskable interrupt having lower priority.
33. b) 0024H
34. b) intel 4004
The Intel 4004 is a 4-bit central processing unit (CPU) released by Intel Corporation in 1971. It was the first commercially available microprocessor by Intel.
35. d) All the above
36. d) NAND

40. a) Initial, Repeatable, Defined, Managed, Optimized.
41. b) Process
42. a) Coupling
In software engineering, coupling is the degree of interdependence between software modules; a measure of how closely connected two routines or modules are; the strength of the relationships between modules. Coupling is usually contrasted with cohesion. Low coupling often correlates with high cohesion, and vice versa.
