Unit, GHz (gigahertz)
What is a bit? What is a byte? - Answers A bit is a binary digit 0 or 1. A byte is a sequence of 8 bits.
What is memory? - Answers storage and retrieval of information
What does RAM stand for? - Answers random access memory.
What unit is used to measure memory size? What unit is used to measure disk size? - Answers GB, GB or
TB
What is the primary difference between memory and storage devices. - Answers temporary storage of
data versus permanent storage of data.
What language does the CPU understand? - Answers machine language
What is an assembly language? - Answers referred to as a low-level language, because it is close in
nature to machine language. It was created in the early days of computing as an alternative to machine
language.
What is an assembler? - Answers used to translate assemble-language programs into machine code.
What is an interpreter? - Answers a program used to translate your source code into executable
machine code statement by statement executing as it goes.
What is a compiler? - Answers a program used to translate your entire source code into executable
machine code before executing.
What is the difference between an interpreted language and a compiled language? - Answers the first
translates and executes the program one statement at a time while the second translates the entire
source program into machine-language file for execution.
What is an operating system? - Answers the software that supports a computer's basic functions, such as
scheduling tasks, executing applications, and controlling peripherals.
List some popular operating systems. - Answers Microsoft Windows, Mac OS and Linux
, What are the major responsibilities of an operating system? - Answers Controlling and monitoring
system activities, allocating and assigning system resources and scheduling operations.
Multiprogramming - Answers allowing multiple programs to run in main memory at the same time while
sharing the same CPU
Multithreading - Answers allows multiple commands to run simultaneously within one program
multiprocessing - Answers running multiple programs concurrently using multiple processors
Java - Answers An object-oriented programming language designed specifically for programs
(particularly multimedia) to be used over the Internet allowing programmers to create small programs
or applications to enhance websites.

purposes in the program
Java keywords - Answers class, public, static, void
Is Java case sensitive? - Answers yes
What is the case for Java keywords? - Answers lowercase
What is a comment? - Answers not a programming statement and is ignored by the compiler but there
to help programmers to communicate and understand the program
