A set of standards for physically connecting and transferring data between computers and peripheral devices:

  1. Small Computer System Interface

  2. Small Connection System Interface

  3. Secure Connection Server Interface

  4. Small Connection Sys Interface


Correct Option: B

AI Explanation

To answer this question, you need to understand the concept of standards for physically connecting and transferring data between computers and peripheral devices.

Let's go through each option to understand why it is correct or incorrect:

Option A) Small Computer System Interface (SCSI) - This option is incorrect because SCSI is a set of standards for connecting and transferring data between computers and peripheral devices, but it is not the correct answer in this context.

Option B) Small Connection System Interface - This option is the correct answer. It correctly describes a set of standards for physically connecting and transferring data between computers and peripheral devices.

Option C) Secure Connection Server Interface - This option is incorrect because there is no such widely recognized set of standards with this name for connecting and transferring data between computers and peripheral devices.

Option D) Small Connection Sys Interface - This option is incorrect because it does not provide a complete or accurate description of the set of standards for physically connecting and transferring data between computers and peripheral devices.

The correct answer is B) Small Connection System Interface because it accurately describes the set of standards for physically connecting and transferring data between computers and peripheral devices.
