B Correct answer
Explanation

DIN 5 connectors, also known as 180-degree 5-pin DIN connectors, were famously used on early IBM PC and compatible computer keyboards, such as the Model F and Model M keyboards.

Multiple choice

Which of the following connections to the computer is correct for the devices-keyboard, mouse and printer, respectively?

  1. Parallel port, PS2, serial port

  2. PS2, serial port, PS2

  3. PS2, PS2, parallel port

  4. Serial port, parallel port, PS2
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Keyboards and mice traditionally connect via PS/2 ports, while printers use parallel ports. Option C correctly matches keyboard-PS2, mouse-PS2, printer-parallel port. Other options either mismatch the ports or incorrectly assign serial ports to these devices.

Multiple choice

A Correct answer
Explanation

486 DX included a built-in math co-processor,  which is also called numeric co-processor but 486 SX does not have such co-processor.

Multiple choice

Refer to the exhibit. Which term correctly identifies the device type that is included in the area B?

  1. Source

  2. End

  3. Transfer

  4. Intermediary
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Intermediary devices sit between the source and destination in a network communication path. These devices (like routers, switches, or proxies) forward or process traffic as it moves across the network, unlike endpoints which are the actual sources or destinations of the communication. Source and End refer to the communicating endpoints, while Transfer is not a standard networking device classification.
