CSE 2221 EXAM Q&A 2026 STUDY GUIDE
GRADED A+
◉CPU . Answer: Central Processing Unit: The CPU performs
arithmetic, logic, and other operations to transform data input into more
usable information output. The CPU locates and executes the program
instructions; it carries out arithmetic operations such as addition,
subtraction, multiplication, and division; it fetches data from external
memory or devices and places processed data into storage.
◉IDE . Answer: Integrated Development Environment: A software
application that helps programmers develop software code efficiently.
Ex: Eclipse.
◉JVM . Answer: Java Virtual Machine: The runtime engine of the Java
Platform, which allows any program written in Java or other language
compiled into Java bytecode to run on any computer that has a native
JVM. Simulates a real CPU.
◉GUI . Answer: Graphical User Interface: A system of interactive
visual components for a computer or system software is called a GUI
(graphical user interface). GUI is the interface that uses graphical
elements to let people interact as per requirement with electronic devices
including computers, laptops, tablets, and smartphones.
, ◉RSS . Answer: Really Simple Syndication: a format for storing online
information in a way that makes that information readable by lots of
different kinds of software; allows users and applications to access
updates to websites in a standardized, computer-readable format.
◉XML . Answer: Extensible Markup Language: A metalanguage that
allows users to define and store data in a shareable manner. XML
supports information exchange between computer systems such as
websites, databases, and third-party applications.
◉Compiler . Answer: Translates high-level language program into the
more detailed instructions required by the CPU. In this case compiled
Java programs contain instructions for the JVM.
◉Java has two attributes that makes it beginner friendly... . Answer:
Safety and portability.
◉Process of Running Program . Answer: 1. Editor
2. Source File
3. Compiler
4. Class Files
5. Virtual Machine
6. Running Program
