Intro. to Java Programming UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Application Program Interface (API) - CORRECT ANSWER - Also known as a library,
contains predefined classes and interfaces for developing Java programs
Assembler - CORRECT ANSWER - A program to convert assembly language into
machine language
Assembly Language - CORRECT ANSWER - Low-Level language created to ease the
code writing.
Bit - CORRECT ANSWER - A unit of measurement of information, 0 & 1 create digits
known as the binary number system.
Block - CORRECT ANSWER - Curly braces {}, every class has class blocking that
groups the data and methods of the class.
Block Comment - CORRECT ANSWER - (/*) Creates a block comment, computers will
read the first (/*) and ignore all text until the final (*/). (for multiply line instructions or
comments)
Bus - CORRECT ANSWER - Subsystem of computer components that power and data
flow through.
Byte - CORRECT ANSWER - a sequence of 8 bits (enough to represent one character of
alphanumeric data) processed as a single unit of information
Bytecode - CORRECT ANSWER - Is similar to machine instructions but is architecture
neutral and can run on any platform that has a JVM.
,Bytecode Verifier - CORRECT ANSWER - Checks the validity of the Bytecode and to
ensure that the Bytecode does not violate Java's security restrictions.
Cable Modem - CORRECT ANSWER - Uses the cable TV line maintained by the cable
company and is generally faster than DSL
Central Processing Unit (CPU) - CORRECT ANSWER - The part of a computer (a
microprocessor chip) that does most of the data processing. 2 parts; Control Unit and
Arithmetic/LogicUnit.
Class Loader - CORRECT ANSWER - Is a part of the Java Runtime Environment that
dynamically loads Java classes into the Java Virtual Machine. Usually classes are only loaded on
demand. The Java run time system does not need to know about files and file systems because of
class loaders.
Comment - CORRECT ANSWER - Help programmers to communicate and understand
the program. (//) single line comment. (/**/) multiply line comment
Compiler - CORRECT ANSWER - Is a computer program (or set of programs) that
transforms source code written in a programming language into another computer language (the
target language, often having a binary form known as object code). The most common reason for
wanting to transform source code is to create an executable program.
Console - CORRECT ANSWER - Is an old computer term that refers to the text entry and
display device of the computer.
Dot Pitch - CORRECT ANSWER - The amount of space between pixels, measured in
millimeters. The smaller the dot pitch the sharper the display.
Digital Subscriber Line (DSL) - CORRECT ANSWER - Is a family of technologies that
provide Internet access by transmitting digital data over the wires of a local telephone network.
, Encoding Scheme - CORRECT ANSWER - Is a set of rules that govern how a computer
translates characters, numbers, and symbols into data the computer can actually work with.
Hardware - CORRECT ANSWER - In general hardware comprises the visible physical
elements of the computer.
High-Level Language - CORRECT ANSWER - Is a programming language with strong
abstraction from the details of the computer. In comparison to low-level programming languages,
it may use natural language elements, be easier to use, or may automate (or even hide entirely)
significant areas of computing systems (e.g. memory management), making the process of
developing a program simpler and more understandable relative to a lower-level language.
Integrated Development Environment (IDE) - CORRECT ANSWER - Is a software
application that provides comprehensive facilities to computer programmers for software
development. An IDE normally consists of a source code editor, build automation tools and a
debugger.
Interpreter - CORRECT ANSWER - Changes the source code into machine code for
execution.
Java Command - CORRECT ANSWER - ...
Java Language Specification - CORRECT ANSWER - Is a technical definition of the Java
programming language's syntax and semantics.
Java Virtual Machine (JVM) - CORRECT ANSWER - Iis a virtual machine that can
execute Java bytecode. It is the code execution component of the Java platform.
Javac Command - CORRECT ANSWER - ...
