Question

The unit used to measure the speed and direction of movement of a computer mouse is called......

• A. Mashboard
• B. RSTP
• C. Mickey
• D. SDP

Hint:

The unit is named after the mouse itself, playfully borrowing the name of a famous cartoon mouse.

Answer 1

The Correct Option is C

This is a piece of computer hardware trivia about how a mouse's tiny movements are measured internally. The correct term is a real, if unusual sounding, unit used in engineering documentation for pointing devices.

1. Mashboard: This is not a recognised computing term related to mouse movement.
2. RSTP: RSTP stands for Rapid Spanning Tree Protocol, a networking protocol used to prevent loops in Ethernet networks. It has nothing to do with mouse movement.
3. Mickey: A mickey is the actual unit used to describe the smallest detectable movement of a computer mouse, roughly one two hundredth of an inch. Mouse sensitivity is often expressed in "mickeys per inch," and the unit is playfully named after the cartoon character Mickey Mouse, tying back to the mouse's own name.
4. SDP: SDP commonly refers to Session Description Protocol, used for streaming media sessions, which is unrelated to mouse hardware.

Of the four options, only "mickey" is a real, documented measurement unit in mouse hardware specifications, describing how far and in what direction the mouse has moved.

Let's summarize:

• A mickey measures the smallest unit of movement a mouse sensor can detect, about one two hundredth of an inch.
• The other three options are unrelated terms borrowed from networking or streaming, or are not real technical terms at all.

The correct answer is Mickey.
