Correct answer

Answer: (a)A.

Preventing unauthorised access to computer via the internet

Why this answer is correct

The correct answer is Preventing unauthorised access to computer via the internet.

Key Points

  • A firewall is a security system designed to protect computers and networks by preventing unauthorized access from external sources, such as hackers or malware.
  • It acts as a barrier between a trusted internal network and untrusted external networks, such as the internet.
  • Firewalls monitor and filter incoming and outgoing network traffic based on predefined security rules.
  • They can be implemented as hardware devices, software applications, or a combination of both.
  • By blocking suspicious or malicious traffic, firewalls help safeguard sensitive data and maintain system integrity.

Additional Information

  • Types of Firewalls:
  • Packet Filtering Firewalls: Analyze packets of data and allow or block them based on predefined rules.
  • Stateful Inspection Firewalls: Monitor the state of active connections and make decisions based on context.
  • Proxy Firewalls: Act as intermediaries between users and the internet, filtering requests and responses.
  • Next-Generation Firewalls (NGFWs): Include additional features like intrusion prevention systems (IPS) and deep packet inspection.
  • Key Terminologies:
  • Intrusion Prevention System (IPS): A technology integrated into advanced firewalls to detect and block malicious activities.
  • Network Address Translation (NAT): A feature used by firewalls to mask internal IP addresses from external networks.
  • Demilitarized Zone (DMZ): A separate network segment created by firewalls to host public-facing services securely.
  • Advantages of Firewalls:
  • Prevents unauthorized access and safeguards against cyber threats.
  • Monitors network traffic to detect and block malicious activities.
  • Enhances security for home and enterprise networks.
  • Limitations of Firewalls:
  • Cannot protect against internal threats or attacks from trusted devices.
  • Requires regular updates to stay effective against evolving threats.
  • May cause slight network latency due to traffic monitoring.

View answer & explanation

Correct answer

Answer: (d)D.

Linker

Why this answer is correct

The correct answer is Linker.

Key Points

  • A Linker is classified as a system software, not an application software.
  • System software like Linker is used to manage and control computer hardware and serves as a platform for other software.
  • The primary function of a Linker is to combine multiple object files (produced by the compiler) into a single executable file.
  • Application software, on the other hand, includes programs designed for end-users, such as spreadsheets (e.g., MS Excel), presentation tools (e.g., MS PowerPoint), and design software (e.g., AutoCAD).
  • Linkers are essential in software development and programming but do not directly serve end-user tasks or applications.

Additional Information

  • Application Software:
  • Application software is designed to help users perform specific tasks, such as word processing, spreadsheet management, and graphic design.
  • Examples include MS PowerPoint, MS Excel, AutoCAD, web browsers, and media players.
  • Application software is user-oriented and directly interacts with the end-user.
  • System Software:
  • System software acts as an intermediary between hardware and application software.
  • Examples include operating systems (e.g., Windows, Linux), compilers, and linkers.
  • System software is primarily designed for managing system resources and enabling the functionality of application software.
  • Linker:
  • A linker is a system software tool used in programming to combine object files into a single executable file.
  • It resolves references between different modules and ensures the program runs correctly.
  • Linkers are a critical part of the software development process, typically used in languages like C, C++, and assembly.
  • Compiler:
  • A compiler is another system software used to translate high-level programming code into machine code.
  • It works alongside the linker to create executable programs.
  • While compilers convert source code into object code, linkers bring together multiple object code files.

  • Firewall
  • A firewall is a network security device that monitors and controls incoming and outgoing network traffic.
  • Firewalls help protect systems from unauthorized access by blocking harmful traffic.
  • Unlike malware, firewalls are defensive tools rather than malicious software.
  • Hacking
  • Hacking refers to the unauthorized access to or manipulation of computer systems or networks.
  • It is a method, not a type of software.
  • Ethical hacking is the legitimate use of hacking techniques to improve security systems.
  • Password Cracking
  • Password cracking is the process of recovering passwords from data stored in or transmitted by a computer system.
  • It is a technique used by hackers to gain unauthorized access, not a form of software.
