Java Terms Exam 2025 Questions
and Answers
Application Program Interface (API) - ANSWER✔✔-Stands for "Application
Programming Interface." An API is a set of commands, functions, protocols, and objects
that programmers can use to create software or interact with an external system. It
provides developers with standard commands for performing common operations so
they do not have to write the code from scratch.
Assembler - ANSWER✔✔-An assembler is a program that converts assembly language
into machine code. It takes the basic commands and operations from assembly code and
converts them into binary code that can be recognized by a specific type of processor.
Assembly Language - ANSWER✔✔-An assembly language is a low-level programming
language designed for a specific type of processor. It may be produced by compiling
source code from a high-level programming language (such as C/C++) but can also be
written from scratch. Assembly code can be converted to machine code using an
assembler.
,Bit - ANSWER✔✔-A bit (short for "binary digit") is the smallest unit of measurement
used to quantify computer data. It contains a single binary value of 0 or 1.
Block - ANSWER✔✔-A block in Java is a group of one or more statements enclosed in
braces. A block begins with an opening brace ({) and ends with a closing brace (}).
Between the opening and closing braces, you can code one or more statements. For
example: { int i, j; i = 100; j = 200; } A block is itself a type of statement.
Block Comment - ANSWER✔✔-A block comment method is declared as follows: /*
*block comment describing the overview of the code. */ Single-line comments are short
comments that may be written in a single line. ... Documentation comments, written
before the declaration, are used to explain Java interfaces, classes, constructors, methods
and fields
Bus - ANSWER✔✔-While the wheels on the bus may go "round and round," data on a
computer's bus goes up and down. Each bus inside a computer consists of set of wires
that allow data to be passed back and forth. Most computers have several buses that
transmit data to different parts of the machine. Each bus has a certain size, measured in
bits (such as 32-bit or 64-bit), that determines how much data can travel across the bus
at one time. Buses also have a certain speed, measured in megahertz, which determines
how fast the data can travel.
, Byte - ANSWER✔✔-A byte is a unit of measurement used to measure data. One byte
contains eight binary bits, or a series of eight zeros and ones. Therefore, each byte can
be used to represent 2^8 or 256 different values.
Bytecode - ANSWER✔✔-Bytecode is program code that has been compiled from source
code into low-level code designed for a software interpreter. It may be executed by a
virtual machine (such as a JVM) or further compiled into machine code, which is
recognized by the processor.
Bytecode verifier - ANSWER✔✔-Bytecode Verification. When a class loader presents
the bytecodes of a newly loaded Java platform class to the virtual machine, these
bytecodes are first inspected by a verifier. The verifier checks that the instructions
cannot perform actions that are obviously damaging.
Cable modem - ANSWER✔✔-A cable modem is a peripheral device used to connect to
the Internet. It operates over coax cable TV lines and provides high-speed Internet
access. Since cable modems offer an always-on connection and fast data transfer rates,
they are considered broadband devices.
Central Processing Unit (CPU) - ANSWER✔✔-Stands for "Central Processing Unit." The
CPU is the primary component of a computer that processes instructions. It runs the
operating system and applications, constantly receiving input from the user or active
software programs. It processes the data and produces output, which may stored by an
application or displayed on the screen.
