COMPUTER SCIENCE AN OVERVIEW
CHAPTERS 1 TO 8 FINAL PAPER 2026 SOLVED
QUESTIONS WITH FULL SOLUTION ALREADY
PASSED
◉ cyclical redundancy check.
Answer: a code added to data that is used to detect errors occurring
during transmission, storage, or retrieval
◉ data models.
Answer: the analysis of data objects and their relationships to other
data objects. Often the first step in database design.
◉ database relationships.
Answer: a situation existing between two relational database tables;
one table has a foreign key that references the primary key of the
other table. Relationships allow relational databases to split and
store data in different tables, while linking disparate data items
◉ decryption.
Answer: process of taking encoded or encrypted text and converting
it back into text that you or the computer can read and understand.
, ◉ defragmentation.
Answer: process that reduces amount of fragmentation by physically
organizing the contents of a mass storage device into the smallest
number of contiguous regions (fragments).
◉ direct access.
Answer: retrieving data immediately from any part of a computer
file without having to read the file from the beginning.
◉ Easy Cache.
Answer: takes real-time snapshot of every page, post, category, link,
etc. Snapshots are then stored (cached) into folder of your choice, so
they can be referenced and served to the visitor later, in order to
save database processing time that has been slowing your website
down.
◉ encryption.
Answer: activity of converting data or information into code
◉ ethernet.
Answer: a network protocol that controls how data is transmitted
over a LAN (local area network)
