Answer

Binary

Answer

Octal

Answer

Decimal

Question 3

A digital image is stored in a file that retains all original data without any loss. Later, the file is compressed using a technique that discards some data to reduce file size, but the image quality is lower. Which type of compression was applied?

Accepted Answer

Lossy compression. Lossy compression permanently removes data to reduce file size, resulting in quality loss. Lossless compression retains all data. JPEG is a lossy format.

Answer

Archive compression

Answer

Lossless compression

Answer

File compression

Question 4

A user notices that their computer runs slowly when multiple applications are open simultaneously. Which hardware component is most likely insufficient for the current workload?

Accepted Answer

RAM. RAM (Random Access Memory) is volatile memory used to store data for running programs. Insufficient RAM causes the system to use slower storage (paging), slowing performance.

Answer

GPU

Answer

CPU

Answer

Hard drive

Question 5

An IT professional is explaining to a client the difference between an HDD and an SSD. Which statement best describes a key advantage of an SSD over an HDD?

Accepted Answer

SSDs are more resilient to physical shock because they have no moving parts.. SSDs use flash memory and have no moving parts, making them faster, more durable, and quieter than HDDs, which use spinning platters and mechanical arms.

Answer

SSDs require a constant power supply to retain data.

Answer

SSDs provide larger storage capacities at a lower cost per gigabyte.

Answer

SSDs use laser technology to read and write data.

Question 6

A technician is troubleshooting a computer that fails to boot. The technician checks the system's low-level software stored on a chip on the motherboard. Which type of software is being inspected?

Accepted Answer

Firmware. Firmware is software embedded in hardware devices, such as BIOS/UEFI on the motherboard, which initializes hardware during boot.

Answer

Device driver

Answer

Application software

Answer

Operating system

Question 7

A company wants to use a cloud service where they can deploy their own applications on virtual machines without managing the underlying hardware. Which cloud service model best fits this requirement?

Accepted Answer

Infrastructure as a Service (IaaS). IaaS (Infrastructure as a Service) provides virtualized computing resources. The customer manages OS and apps, while the provider manages the hardware.

Answer

Software as a Service (SaaS)

Answer

Function as a Service (FaaS)

Answer

Platform as a Service (PaaS)

Question 8

A student is converting the hexadecimal number 2F to decimal. What is the correct decimal value?

Accepted Answer

47. Hexadecimal 2F: 2*16 + 15 = 32 + 15 = 47.

Answer

59

Answer

32

Answer

63

Question 9

A network technician needs to perform a bitwise AND operation on two binary numbers: 10110110 and 11001101. What is the result in decimal?

Accepted Answer

132. Perform AND bitwise: 10110110 AND 11001101 = 10000100 (binary) = 132 decimal.

Answer

172

Answer

196

Answer

128

Question 10

A file is compressed using a lossless algorithm. Which of the following file types is most likely the result?

Accepted Answer

PNG. PNG uses lossless compression. JPEG is lossy. MP3 is lossy audio. ZIP is a lossless archive format. The question asks for a file type (not archive).

Answer

MP3

Answer

JPEG

Answer

ZIP

Question 11

An IT specialist is explaining ASCII and Unicode to a trainee. Which statement accurately describes a difference between ASCII and Unicode?

Accepted Answer

Unicode can represent characters from multiple languages, while ASCII is limited to English.. ASCII uses 7 bits and can represent 128 characters. Unicode is a variable-width encoding that supports characters from many languages.

Answer

ASCII uses 8 bits per character and supports 256 characters.

Answer

Unicode uses 16 bits per character, while ASCII uses 7 bits.

Answer

ASCII is a variable-width encoding, while Unicode uses a fixed width.

Question 12

Which of the following best describes the role of an operating system?

Accepted Answer

It manages hardware resources and provides a platform for applications.. An OS manages hardware resources and provides services for application software. It acts as an intermediary between user and hardware.

Answer

It runs only one application at a time.

Answer

It is responsible for data backup and recovery.

Answer

It connects the computer to the internet.

Question 13

A company is choosing between public, private, and hybrid cloud deployments. Which TWO statements correctly describe characteristics of these cloud models? (Select TWO.)

Accepted Answer

In a public cloud, resources are shared among multiple organizations.. Public cloud resources are shared across multiple tenants. Private cloud is dedicated to a single organization. Hybrid combines both.

Answer

Public cloud offers the highest level of control over security.

Answer

Private cloud requires no upfront capital expenditure.

Answer

0 XOR 1 = 1. XOR outputs 1 when inputs differ. 1 XOR 0 = 1. Also, 0 XOR 1 = 1. So both pairs produce 1.

Answer

1 XOR 0 = 0

Answer

1 XOR 1 = 1

Answer

0 XOR 1 = 0
