You are installing two hard disk drives on a computer. Which of the following possible combinations can be used? Each correct answer represents a complete solution. Choose of that apply.
- A.
Install the second hard disk drive on the primary IQE Controller. Designate one drive as Master and the other as Slave
- B.
Install the second hard drive disk on the secondary IDE controller ensuring that the first drive is on primary IDE controller. Designate both drives as Master
- C.
Install the second hard disk drive on the secondary IDE controller ensuring that the first hard disk is on the primary controller. Designate the second hard disk drive as Slave
- D.
Install both the hard disk drives as the Primary IDE Controller. Designate both drives as Secondary
Correct Answer(s)
A. Install the second hard disk drive on the primary IQE Controller. Designate one drive as Master and the other as Slave
B. Install the second hard drive disk on the secondary IDE controller ensuring that the first drive is on primary IDE controller. Designate both drives as MasterExplanation
The correct answer is to install the second hard disk drive on the primary IQE Controller and designate one drive as Master and the other as Slave. This is because the primary IQE Controller is designed to handle multiple drives, with one drive being the Master and the other being the Slave. Additionally, installing the second hard drive disk on the secondary IDE controller and designating both drives as Master is also a correct solution. This is because the secondary IDE controller can also handle multiple drives, and designating both drives as Master allows them to be recognized and accessed by the computer.Rate this question:

Which of the following sleep mode is the most power hungry mode?
- A.
S1
- B.
S2
- C.
S0
- D.
S3
Correct Answer
A. S1Explanation
S1 sleep mode is the most power hungry mode because it is a fully powered state where the CPU and other components are still running, consuming a significant amount of power. In this mode, the system is idle but ready to respond quickly to any input or task, resulting in higher power consumption compared to the other sleep modes. S2, S0, and S3 sleep modes are all lower power states with varying levels of power consumption and responsiveness.Rate this question:

Which of the following software displays advertisements, whether or not the user has consented?
- A.
Trojan Horse
- B.
Honeypot
- C.

Adware
Correct Answer
D. AdwareExplanation
Adware is a type of software that displays advertisements, regardless of whether the user has given consent or not. Unlike other types of software mentioned in the question, such as Trojan Horse, Honeypot, and Spyware, which have different purposes, adware specifically focuses on delivering advertisements to users. This can be in the form of pop-up ads, banners, or even redirecting web pages. Adware is often bundled with other software and installed without the user's knowledge or explicit consent, making it an intrusive and unwanted form of software.Rate this question:

Which of the following protocols transmits error messages and network statistics?
- A.
ICMP
- B.
DHCP
- C.
TCP
- D.
NNTP
Correct Answer
A. ICMPExplanation
ICMP (Internet Control Message Protocol) is the correct answer because it is specifically designed to transmit error messages and network statistics. ICMP is used by network devices to send error messages, such as "destination unreachable" or "time exceeded," back to the source IP address. It is also used for network diagnostics and troubleshooting, providing information about network connectivity, latency, and other statistics. DHCP (Dynamic Host Configuration Protocol) is responsible for assigning IP addresses to devices on a network. TCP (Transmission Control Protocol) is responsible for establishing reliable connections between devices. NNTP (Network News Transfer Protocol) is used for distributing, querying, and retrieving news articles.Rate this question:
