What type of communication occurs between a computer and a keyboard?

  • AFull-Duplex
  • BSimplex
  • CHalf-Duplex
  • DMultiplex
Permalink
Correct Answer: Option B ā€” Simplex
Explanation: Simplex communication is a one-way communication method in which data flows in only one direction. In the case of a keyboard and a computer, the keyboard sends input signals to the computer, but it does not receive data back for communication purposes. Therefore, this interaction is commonly classified as simplex communication in computer networking and data communication concepts.

Which protocol is commonly used to create a secure and encrypted communication channel over the Internet?

  • AHTTPS (SSL/TLS)
  • BFTP
  • CDHCP
  • DTelnet
Permalink
Correct Answer: Option A ā€” HTTPS (SSL/TLS)
Explanation: HTTPS (HyperText Transfer Protocol Secure) uses SSL/TLS encryption to protect data exchanged between a user's browser and a web server. It ensures confidentiality, integrity, and authentication of information, preventing attackers from intercepting or modifying sensitive data such as passwords, payment details, and personal information while it is transmitted over potentially insecure networks.

What is the main purpose of a Firewall in a computer network?

  • ATo prevent unauthorized access
  • BTo remove all viruses from a computer
  • CTo increase internet speed
  • DTo store network Data
Permalink
Correct Answer: Option A ā€” To prevent unauthorized access
Explanation: A Firewall is a network security system that monitors and controls incoming and outgoing traffic based on predefined security rules. Its primary purpose is to prevent unauthorized users, hackers, or malicious programs from accessing a computer or network. While a firewall can help block some threats, it is not a substitute for antivirus software and does not increase network speed.

Which bus is primarily responsible for transferring data between the CPU and memory?

  • AAddress Bus
  • BExpansion Bus
  • CControl Bus
  • DData Bus
Permalink
Correct Answer: Option D ā€” Data Bus
Explanation: The Data Bus is used to transfer actual data between the CPU, memory, and other hardware components. It carries information in both directions, allowing the processor to read data from memory and write data back to it. The width of the data bus affects how much data can be transferred at one time, influencing overall system performance and speed.

Which sorting algorithm generally provides the best average-case performance for large datasets?

  • AQuick Sort
  • BMerge Sort
  • CBubble Sort
  • DSelection Sort
Permalink
Correct Answer: Option A ā€” Quick Sort
Explanation: Quick Sort is often considered the fastest sorting algorithm in the average case because it has an average time complexity of O(n log n) and requires relatively low memory. It works by selecting a pivot element and partitioning the array into smaller subarrays. Although its worst-case complexity is O(nĀ²), careful pivot selection usually results in very efficient performance in real-world applications.

Which memory type is most commonly used to store firmware in embedded systems?

  • ARAM
  • BVirtual Memory
  • CCache Memory
  • DROM
Permalink
Correct Answer: Option D ā€” ROM
Explanation: ROM (Read-Only Memory) is commonly used to store firmware in embedded systems because it retains data even when power is turned off. Firmware contains essential instructions required for hardware initialization and operation. Unlike RAM, ROM provides non-volatile storage, making it reliable for permanent system software and device control programs.
