COMPREHENSIVE TEST PAPER QUESTIONS
WITH VERIFIED SOLUTIONS RESOURCE
●● Benchmarking
Answer: Running a program on many data sets to be sure its
performance falls within required limits; timing the same algorithm on
two different machines.
●● Code library
Answer: A collection of thoroughly tested object code for various useful
tasks.
●● Coding
Answer: The process of translating the detailed designs into computer
code.
●● Divide-and-conquer
Answer: A program design strategy in which tasks are broken down into
subtasks, which are broken down into sub-subtasks, and so on, until each
piece is small enough to code comfortably. These pieces work together
to accomplish the total job.
,●● Empirical testing
Answer: Designing a special set of test cases and running the program
using these test data.
●● Executable module
Answer: The resulting object code after a linker inserts requested code
from code libraries.
●● External documentation
Answer: Any materials assembled to clarify the program's design and
implementation.
●● Feasibility study
Answer: A step in the software development life cycle that evaluates a
proposed project and compares the costs and benefits of various
solutions.
●● Integrated development environment (IDE)
Answer: A collection of programs that support software development,
such as debuggers, editors, toolkits, and libraries, that lets programmers
perform several tasks within the shell of a single application.
●● Integration testing
,Answer: After unit testing, integration testing is done to see that the
modules communicate the necessary data between and among
themselves and that all modules work together smoothly.
●● Internal documentation
Answer: Documentation that is part of the program code itself.
●● Logic error
Answer: An error in the algorithm used to solve a problem.
●● Object code
Answer: Machine language instructions.
●● Pair programming
Answer: Involves two programmers at a single workstation. At any
given point in time, one is writing code and the other is actively
observing, watching for possible errors
but also thinking about the overall approach.
●● Problem specification
Answer: A step in the software development life cycle that involves
developing a clear, concise, and unambiguous statement of the exact
problem the software
, is to solve.
●● Procedural language
Answer: A program written in a procedural language consists of
sequences of statements that manipulate data items.
●● Program design phase
Answer: A step in the software development life cycle that plans the
structure of the software to be written.
●● Program maintenance
Answer: The process of adapting an existing software product due to
errors, new system requirements, or changing user needs.
●● Program verification
Answer: Used to prove that if the input data to a program satisfies
certain conditions, then, after the program has been run on these data,
the output data satisfies certain other conditions.
●● Regression testing
Answer: If anything is changed on an already-tested module, regression
testing is done to be sure that this change has not introduced a new error
into code that was previously correct.
