    Which of these is used to compile java codes?  - ProProfs

    Which of these is used to compile java codes? 

    • Jar

    • Java

    • Javadoc

    • Javac

    Correct Answer
    A. Javac
    Explanation
    Javac is used to compile Java codes. Javac is the Java compiler that converts Java source code into bytecode, which can then be executed by the Java Virtual Machine (JVM). It is a command-line tool that takes the source code files as input and produces the corresponding bytecode files as output. Javac is an essential tool in the Java development process, as it ensures that the code is syntactically and semantically correct before it can be executed.

    • Java Decompilation Kit

    • None of the above

    Correct Answer
    A. Java Developer Kit
    Explanation
    The correct answer is Java Developer Kit. JDK stands for Java Developer Kit, which is a software development kit used by developers to create, compile, and run Java applications. It includes tools such as the Java compiler, debugger, and other utilities that are necessary for Java development. The Java Developer Kit is essential for anyone who wants to develop Java applications.

    What is a JVM?  - ProProfs

    What is a JVM? 

    • Assembler

    • Debugger

    • Interpreter

    • Compiler

    Correct Answer
    A. Interpreter
    Explanation
    A JVM (Java Virtual Machine) is an interpreter that executes Java bytecode. It converts the bytecode into machine code, which can be understood and executed by the underlying operating system. The JVM acts as a runtime environment for Java applications, allowing them to be platform-independent. It interprets the bytecode line by line and executes the instructions accordingly, making it the correct answer in this case.

    How many bits are in a single IP address? - ProProfs

    How many bits are in a single IP address?

    • 8

    • 16

    • 32

    • 64

    Correct Answer
    A. 32
    Explanation
    An IP address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It consists of a series of 32 bits, which are typically represented as four sets of numbers separated by periods. Each set can range from 0 to 255, which is equivalent to 8 bits. Therefore, a single IP address contains 32 bits.

    How many ports of TCP/IP are reserved for specific protocols? - ProProfs

    How many ports of TCP/IP are reserved for specific protocols?

    • 1024

    • 2048

    • 4096

    • 8192

    Correct Answer
    A. 1024
    Explanation
    The correct answer is 1024. In TCP/IP, there are 1024 ports reserved for specific protocols. These ports are used to establish communication between devices over the internet. Each port is assigned to a specific protocol or service, allowing different applications to communicate with each other. By reserving these ports, it ensures that there is no conflict or interference between different protocols or services using the same port number.

    Which of these consist of data and methods? - ProProfs

    Which of these consist of data and methods?

    • Variable

    • Class

    • Vectors

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    All of the options mentioned consist of both data and methods. A variable is a named storage location that holds a value, and it can also have associated methods. A class is a blueprint for creating objects, and it contains both member variables (data) and member functions (methods). Vectors are a type of data structure that can hold multiple values, and they also have associated methods for manipulating and accessing the data. Therefore, all of the given options consist of both data and methods.
