The answer to this is Optical mouse.
The reason the answer is optical mouse is because the optical mouse is a computer mouse which uses a light source, typically a light-emitting diode, and a light detector, such as an array of photodiodes, to detect movement relative to a surface.

Answer:
It is not valid
Explanation:
I'll assume the question relates to cell referencing in Microsoft Excel.
To reference a cell in Excel, we make use of the following steps:

Hence, 7b is invalid.

In relation to computer processors, a core
is the processing kinda like a brain we ppl have, this is the unit that receives instructions and performs
calculations, or actions, based on those instructions like when you click something. A set of
instructions can allow a software program perform a specific function.
Processors can have a single core or multiple cores that do many different things.
Hopefully i helped you, please mark brainly if possible.</span><span />
