2026 QUESTIONS WITH VERIFIED
ANSWERS
Shareware - correct answer -software that is available free of charge and often distributed
informally for evaluation, after which a fee may be requested for continued use.
Freeware - correct answer -Software that is given away free of charge, but whose author still
retains all rights.
Public Domain Software - correct answer -No EULA and no intellectual property protections and
is available for anyone to download and use at their own discretion.
Complier - correct answer -Translates source code into machine language. A compiler checks
source code for errors before translating it into object code. e.g. C, C++, C#, and Java programs
Interpreter - correct answer -Translate and execute source code into machine language one line
at a time. If the interpreter finds an error, the process is terminated at the statement containing
the error and displays an error message. e.g., Python and Pearl
,C++ - correct answer -Uses a vocabulary and a set of rules for instructing a computer to perform
certain tasks.
Python - correct answer -An easy-to-use programming language that does not require a
compiler for debugging.
JavaScript - correct answer -A programming language designed to enable user engagement with
dynamic elements on web pages.
Tcl (Tool Command Language) - correct answer -Often used in rapid prototyping and the
creation of GUIs, it is a simple and compact language but is also very powerful.
PHP (Hypertext Preprocessor) - correct answer -An all-purpose language that is especially
suitable for web development.
Algorithm - correct answer -a step-by-step procedure for solving a problem
Database Management System (DBMS) - correct answer -Converts large amounts of data into a
usable format to help users make business decisions
DBMS Two Major Layer - correct answer -Application layer and database management layer
, Application Layer - correct answer -Communicates with the end user and can be fairly complex.
(Consists of programs and services within a server that queries the database on behalf of the
client)
Database Table (Datasheet) - correct answer -a collection of related records that contain fields
to organize data
Common Database Models - correct answer -Flat-File, Relational, Hierarchical, and Object-
Oriented
Flat-file database - correct answer -Store data in a plain text. Each line of text file holds one
record. It cannot contain multiple tables.
Hierarchical Database - correct answer -One of the oldest database models. Data is organized in
a tree structure. There is one parent for each record, with optional nodes, forming sub-trees
called segments. Access to the data is predictable and restricted to the paths in the trees.
Relational databases - correct answer -Contain database tables that can be joined together in
logical ways.
