Correct answer is (b) Dynamic

The CC (Carbon Copy) field allows you to specify recipients who are not direct addressees (listed in the "To" field). This field is optional. The BCC (Blind Carbon Copy) Field is similar to CC, expect the recipients are secret. Each BCC recipient will receive the e-mail, but will not see who else received a copy.

1. Reduced corruption, 

2. High transparency, 

3. Increased convenience, 

4. Reduction in overall cost, 

5. Expanded reach of government.

A root kit is a collection of tools that are used to obtain administrator-level access to a computer or a network of computers. A root kit could be installed on your computer by a cyber criminal exploiting a vulnerability or security hole in a legitimate application on your PC and may contain spyware that monitors and records keystrokes.

A webpage is a page of a Website. A web that page can be copied and or send to a friend for review whereas websites are collections of multiple page that must be navigated to view other content.

Websites that displays marks of public Examinations and Entrance Examinations changes when different register numbers are given. Such websites are called as Dynamic Websites.

Eg : Websites of Government and Entranace Exams.

Web pages are called Static websites as the y remain the same whenever it is visited. Examples of static websites are website owned by Small business organizations, School websites etc

Correct answer is  (a) chrome

Correct answer is (a) website

(c) Apple Inc

Correct answer is (b) Apple

The output is “04802828159”. That is the string “0480″ concatenates(joins) the number 2828159. The output is a string, not a number.

Differences between CUI and GUI are as follows:

Kernel is like heart of operating system which plays a vital role in modern OS. Kernel is a program that manages I/O requests and translate them into data processing instructions for CPU and other components. It is a part of the OS that loads first and it remains in the main memory.

Linux is an open source operating system, means anyone can download it and use it without any fees. 

It is similar to Unix in its working and difficult to understand. It is an OS that controls your computer system.

(a) True, The value is case sensitive

 Correct answer is (b) isNaN()

1. Monitors the performance of the system, enables software to communicate with hardware, enables applications, software to be loaded; gives prompts and error reports to the users. 

2. Command-driven user interface means CUI, by which a user gives instructions via typing command onto the computer.

(c) Apple is not an OS while it is the name of a company

Even though a function is defined within the body section, it will not be executed, if it is not called is True.

Christy should use tolower case() function.

Difference between hard and soft real-time OS are as follows:

True 

In time-sharing OS, a small amount of time is allocated for the processing simultaneously.

(b) Real-time operating systems can respond more quickly or predictably to an event than any other OS.

Symbian is the operating system developed and sold by Symbian Ltd.

True 

Operating system is a set of programs that control internal computer operations and make best use of hardware.

The identifiers are case sensitive is True.

(d) C++, It is a programming language others are browsers.

(a) <inputtype=”button”value=”Message” onClick=”Message()">

(b) <input types”button” value=”Message” onMouseEnter=”Message()”>

Some characteristics of modern operating system are as follows: 

1. Microkernel Architecture 

Provide a communication facility between the client program and the various services that are also running in user space. 

2. Multl-Threadlng 

It is a process, which can be divided into threads, that can run simultaneously. In other words, it is the ability of an OS to execute different parts of a program called threads, simultaneously by more than one user at a time. 

(a) Thread 

It is a dispatchable unit of work. It includes a processor context program counter, stack pointer and its own data storage for the stack. It executes sequentially and is interruptible. It is a light weight process. In other words, it is the smallest sequence of program instructions in execution. Threads are managed by OS scheduler. 

(b)  Process 

Process is a collection of one or more threads. Each process have its own address in memory, i.e. each process allocates separate memory area. Switching from one process to another require some time for saving and loading registers, memory maps, updating lists etc.

3. Symmetric Multi-Processing 

In this processing, stand-alone computers with multiple processors that share the common memory and I/O facilities are connected by a communication bus. All processors can perform the same functions. 

4. Object-Oriented Design 

It is used for adding modular extensions to a small kernel. Also, it enable programmers to customise an OS without disrupting system integrity.

To declare a function the keyword function is used.

(d) All the three statements are correct

Server Scripts are the scripts that are executed by the web server.

In JavaScript, a variable is declared using the keyword var.

Client Scripts are the scripts that are executed by the browser.

Correct answer is (a) 0 1 2

if(n== 10)

{

// Execute code block #1

}

else if (n == 20)

{

// Execute code block #2\

}

else if (n == 30)

{

// Execute code block #3

else

{

// If all else fails,

execute block #4

}

Correct answer is  (d) For

Correct answer is (a) while

}

Correct answer is (a) if else

Correct answer is  (d) switch

(d) default structure

(c) while loop

Correct answer is (d) do while

Correct answer is (c) continue

Correct answer is (b) First
