, SECTION I — IT FUNDAMENTALS, HARDWARE,
Questions 1 – 97
SOFT WARE, NET WORKS & SECURITY
1. A protocol provides the rules by which:
A. data is stored on hard drives
B. networks communicate with each other
C. software applications are compiled
D. printers process documents
CORRECT ANSWER B
RATIONALE Protocols are standardized rules governing how data is transmitted and received
across networks — TCP/IP is the most common, required for all Internet
communication.
2. The bus in a computer system permits information to move between each component
through:
A. wireless signals
B. electrical channels that enable communication among electronic components
C. magnetic storage
D. optical fibers
CORRECT ANSWER B
RATIONALE The bus is a set of parallel electrical pathways that carry data, addresses, and
control signals between the CPU, memory, and peripheral components.
,3. In a packet-switched network, a message's pathway is established:
A. before transmission begins and maintained throughout
B. only as it is sent, based on availability and traffic
C. permanently for all future transmissions
D. only during off-peak hours
CORRECT ANSWER B
RATIONALE Packet-switched networks (like the Internet) break messages into packets that
travel independently via the best available routes. Circuit-switched (A) requires a
dedicated path.
4. RAM is ________ memory, meaning data stored in it disappears when the computer is
turned off.
A. non-volatile
B. volatile
C. permanent
D. static
CORRECT ANSWER B
RATIONALE RAM (Random Access Memory) is volatile — it requires power to maintain stored
data. When the computer shuts down, all data in RAM is lost. Hard drives provide
non-volatile storage.
, 5. The IPOS cycle stands for:
A. Input-Processing-Output-Storage
B. Internet-Protocol-Operating-System
C. Integration-Programming-Output-Security
D. Input-Programming-Operating-Storage
CORRECT ANSWER A
RATIONALE The IPOS (Input-Processing-Output-Storage) cycle describes the fundamental
operations of a computer system. Data is input, processed, output for the user,
and stored for future use.
6. The system unit is a critical component of all computer-based systems and consists of:
A. only the monitor and keyboard
B. most of the hardware the computer needs to run
C. only software applications
D. network cables and routers
CORRECT ANSWER B
RATIONALE The system unit houses the motherboard, CPU, RAM, hard drive, power supply,
and expansion components — the core hardware required for computer
operation.
