The correct is Trojan

Key Points

• A Trojan, named after the historical "Trojan horse," is a type of malicious software that disguises itself as a standard, trusted program. Users are often tricked into loading and executing Trojans on their systems because they appear to be useful or interesting software.
• Unlike computer viruses and worms, Trojans are not able to replicate themselves, but once installed, they can deliver their payload.
• This payload can range from stealing sensitive data (such as credit card information or personal identification) to taking over the computer's system resources to use them for illegal activities (like participating in a Distributed Denial of Service attack).
• So, Trojans represent programs that look legitimate and harmless at first glance (this could be software updates, email attachments, or download links), but when they are run or installed, they perform illicit activities secretly, doing harm to user data, privacy, or the computer system itself.

 Additional Information

• Viruses: A computer virus is a type of malicious software that, when executed, replicates itself by modifying other computer programs and inserting its own code. It often spreads to other computers by attaching itself to various programs and executing code when a user launches one of those infected programs.
• Worms: Worms are a type of malware similar to viruses, but they distinguishingly spread without user action. They typically spread across networks by exploiting operating system vulnerabilities, although they can also be spread through email attachments.
• Spyware: Spyware is software that aims to gather information about a person or organization without their knowledge and that may send such information to another entity without the user's consent, or asserts control over a device without the user's knowledge.
• Ransomware: Ransomware is a type of malicious software designed to block access to a computer system or computer files until a sum of money is paid. Most ransomware scams involve hackers encrypting users' data and then selling it back to its owner in exchange for cryptocurrency.
• Rootkits: Rootkits are a type of stealthy malware that's designed to provide continuous privileged access to a computer while actively hiding its existence. The term rootkit represents a combination of words "root" (the traditional name of the privileged account on Unix operating systems) and "kit" (which refers to the software tools that carry out the tool's action).
• Adware: While not always harmful, adware is often intrusive. This type of software automatically generates and shows advertisements when a program is running. While often just annoying, adware can slow down systems and sometimes come bundled with spyware which can violate user privacy.
• Keyloggers: A keylogger is a type of surveillance technology used to monitor and record each keystroke typed on a specific computer's keyboard.

The correct answer is A, C, and D.

Key Points

• Advantages of Computer Networks:
  • File Transfer and Resource Sharing: Networks enable the rapid transfer of large files, including programs and data, and allow shared access to devices such as printers, scanners, and CD-ROM drives. This streamlines operations and optimizes resource use
  • Speed: Transferring and sharing files via a network is quick, saving time and ensuring file integrity is maintained
  • Communication and Collaboration: Networks facilitate various communication methods like email, newsgroups, and video conferencing. They also support collaborative work, allowing multiple users to work on the same project or document simultaneously
  • Increased Storage Capacity: Networks allow computers to share storage space. Data can be stored on off-site servers with regular backups, enhancing storage capacity and data protection.
  • Remote Access: Users can access files and data remotely, even from mobile devices, reducing the need to carry storage devices for data transfer.
  • Centralized Software Management: Networks enable easy sharing of software, with networkable versions of software being more cost-effective than individual licenses. This can significantly reduce costs for large organizations by networking their computers.

The Correct answer is Light fidelity 

Key Points

• Li-Fi:
