D)64 bits

Accepted Answer

A

Question 2

An instance of a value type variable is allocated memory on_______.
A)Stack
B)Heap
C)Both a&b
D)None of these

Accepted Answer

Value type variables are allocated memory on the stack, whereas reference types are allocated on the heap. This is a fundamental characteristic of how .NET manages memory for different types of objects.

Question 3

An instance of a reference type variable is allocated memory on_______.
A)Stack
B)Heap
C)Both a&b
D)None of these

Accepted Answer

Instances of reference types are allocated on the heap, while their references (or variables) are stored on the stack.

Question 4

The size of long is___________.
A)8 bits
B)16 bits
C)32 bits
D)64 bits

Accepted Answer

The size of a long in many modern computing environments is 64 bits. However, it's important to note that this can vary depending on the system architecture and the programming language in question. In the context of C and C++ on a 64-bit system, for example, long is typically 64 bits.

Question 5

________________ access modifier is applied to a method or a data member, it can be accessed by all classes in the same namespace and derived class in other namespace.
A)Public
B)Protected
C)Internal
D)Protected internal

Accepted Answer

Protected internal access modifier allows a member to be accessed by classes within its containing assembly (similar to internal) and also by derived classes located in other assemblies (similar to protected). This combination makes it uniquely capable of the described accessibility.

Question 6

The first type of streams is specially used to represent _________
A)Binary data
B)text
C)data
D)derived

Accepted Answer

The first type of streams is specially used to represent text, which is why option B is correct. Streams in computing can be used for various types of data, but when referring to the "first type," it typically means text streams, which are designed for reading and writing text data.

Question 7

The second type of streams is used to represent __________
A)Data
B)text
C)binary data
D)derived

Accepted Answer

The second type of streams is used to represent binary data, which includes any form of data that is not purely text, such as images, audio, video, and other types of multimedia, as well as executable files.

Question 8

All IO classes that represent streams are derived from the ______ class.
A)Data
B)Stream
C)another
D)none

Accepted Answer

All IO classes that represent streams in many programming environments, especially in .NET framework, are derived from the base class named "Stream" or a similar concept, which provides a generic view of a sequence of bytes.

Question 9

The stream class has been designed to provide functional features for ________ and __________.
A)Creating, manipulating
B)displaying, manipulating
C)Creating, displaying
D)printing, creating

Accepted Answer

The stream class in programming languages like C++ is designed to provide functional features for creating and manipulating streams of data, such as files or input/output streams.

Question 10

The file steam class is designed specifically for reading and writing_______________ files.
A)Class files
B)binary data
C)program
D)none

Accepted Answer

The FileStream class in .NET is designed specifically for reading and writing binary data to and from a file. This makes it suitable for handling all types of files, including images, documents, and any other form of binary data.

Question 11

A buffer is a block of bytes in memory used to ___________
A)Class data
B)binary data
C)cache data
D)data

Accepted Answer

The answer of A buffer is a block of bytes...

Question 12

The Buffered Stream class is a ________ of the Stream class.
A)Base class
B)binary class
C)Derived class
D)class

Accepted Answer

The Buffered Stream class is a derived class of the Stream class, meaning it extends or inherits from the Stream class to provide additional functionalities such as buffering capabilities.

Question 13

The text files are helpful in __________ and ____________ textual data.
A)Storing, displaying
B)storing, retrieving
C)Retrieving, displaying
D)displaying, retrieving

Accepted Answer

Storing and retrieving textual data is the main purpose of text files.

Question 14

A machine on a network is called ________
A)Node
B)data
C)address
D)store

Accepted Answer

A machine on a network is referred to as a "Node." Nodes can be computers, printers, or any other device capable of sending or receiving data on the network.

Question 15

The node is also called as ______________
A)Data
B)class
C)host
D)cache

Accepted Answer

A node in networking is referred to as a connection point, which can be a computer or device that is capable of sending, receiving, or forwarding information over a communications channel, thus "host" is the correct term.

Question 16

The various possible values of dock property are_________
A)TOP, Left
B)Fill, right
C)Side, upright
D)Both (a) and (B)

Accepted Answer

The dock property in many GUI frameworks, such as Windows Forms in .NET, allows a control to be docked to the top, bottom, left, right, or filled in its parent container. Therefore, both options A (TOP, Left) and B (Fill, right) are correct representations of possible values for the dock property. Option C (Side, upright) does not correspond to standard values of the dock property.

Question 17

The ADO.NET provides greater case of ___________
A)Programming
B)higher dependency
C)Improve data source
D)both (a) and (b)

Accepted Answer

The answer of The ADO.NET provides greater case of ___________
A)Programming
B)higher...

Question 18

Only ___________ amount of processing time is needed for data conversion.
A)Large
B)small
C)none
D)allocated time

Accepted Answer

A small amount of processing time is needed for data conversion, as it is typically a straightforward process that doesn't require extensive computational resources.
