Question

question 3 of 10
which phrase is the best definition of a transistor?

a. an efficient electrical switch that is made of semiconducting material

b. a fast electronic device that stores and processes data

c. a simple data storage area for primary computer memory

d. a large microchip that works as a central processing unit

Explanation:

• Option B describes a general computing device, not specifically a transistor.
• Option C refers to primary memory components like RAM cells, not transistors.
• Option D defines a central processing unit (CPU), which contains transistors but is not a transistor itself.
• Option A accurately describes a transistor: it is a semiconductor-based device that acts as an efficient electrical switch (and amplifier), which is its core function.

Answer:

A. An efficient electrical switch that is made of semiconducting material
