A university lab uses Windows, macOS, and Linux workstations. Which statement BEST reflects the functional differences among these operating systems?
Linux is closed-source while Windows and macOS are open-source
Windows excels in creative tools; macOS in gaming; Linux in enterprise servers
macOS tightly integrates with hardware, Windows provides broad compatibility, Linux offers high flexibility
All three OSs share identical system call structures
Firmware differs from drivers because:
Firmware resides in permanent memory and initializes hardware before OS loads
Drivers are burned into chips, while firmware is installed by users
Firmware only manages printers, while drivers manage all devices
Drivers contain OS kernels, firmware contains application APIs
Which step in the boot process comes immediately after the POST (Power-On Self-Test)?
OS initialization
Kernel loading into RAM
BIOS/UEFI firmware activation
User login prompt
A software developer uses APIs when building an application. Which function do APIs serve in this context?
Directly modify kernel scheduling
Provide standardized access to system calls
Replace drivers during boot-up
Increase RAM allocation for apps
Cloud computing relies on virtualization mainly because:
It allows physical storage devices to be permanently replaced with binary files
It enables multiple users and services to share underlying hardware efficiently
It removes the need for encryption in distributed systems
It guarantees zero-latency connections across WANs
In communication systems, which setup allows both sender and receiver to transmit simultaneously?
Simplex
Half-duplex
Full-duplex
Multiplex
A network in a university campus connecting multiple buildings with fiber optics is BEST classified as:
LAN
WAN
MAN
PAN
Which protocol ensures reliable, ordered delivery of data packets across the internet?
HTTP
FTP
TCP/IP
DNS
A company adopts a star topology for its office LAN. What is the PRIMARY disadvantage?
Data collisions increase with more devices
Failure of the central hub disrupts all communication
Data always travels slower than in ring topologies
Network expansion is impossible
Which of the following is NOT a wireless transmission medium?
Radio waves
Infrared
Optical fiber
Microwaves
An e-commerce platform ensures customer credit card details are encrypted during transmission. Which protocol achieves this?
FTP
HTTP
HTTPS
DHCP
In virtualization, a hosted hypervisor differs from a bare-metal hypervisor because:
Hosted hypervisors run directly on hardware, while bare-metal requires OS
Hosted hypervisors run as an application on top of a traditional OS
Bare-metal hypervisors cannot allocate CPU cores dynamically
Bare-metal hypervisors only support Linux guests
Which is the BEST example of software/application virtualization?
Running multiple web servers on one physical machine
Running Windows-only software on macOS using a virtual environment
Combining multiple SSDs into one pool
Dividing network traffic into VLANs
Why are international standards (IEEE, ISO, ITU) critical in protocol design?
They prevent cloud providers from monopolizing services
They ensure global interoperability and compatibility
They eliminate the need for encryption
They simplify proprietary system designs
An IT admin sets up DHCP in a company’s LAN. What is its primary function?
Encrypt data packets
Assign IP addresses automatically
Resolve domain names
Manage email transmission
A multimedia file in AVI format is significantly larger than in MP4 format. Why?
AVI is a compressed lossy format
AVI is uncompressed and retains higher quality
MP4 cannot store multiple tracks
AVI files do not support video playback
Which character encoding is MOST appropriate for multilingual applications?
ASCII
Unicode UTF-8
Morse Code
Hexadecimal
Improper data format selection can lead to:
Increased system security
Miscommunication between systems and inefficiencies
Faster transmission rates
Higher storage compatibility

Discrete
Continuous
Boolean
Integer
The hexadecimal value “2F” in decimal is:
31
45
47
29
Which situation BEST illustrates floating-point precision issues?
