Question

open ended questions: answer the following questions in complete sentences. 11. explain why computers use abstraction when dealing with electricity in wires. 12. describe how a transistor helps a computer decide if a wire is “on” or “off.” 13. why do computers need to use many transistors, not just one or two?

Explanation:

1. Computers use abstraction when dealing with electricity in wires to simplify complex electrical phenomena. By representing electrical states as binary values (0s and 1s), they can focus on logical operations rather than the physical - level details of electricity flow and electrical properties, making it easier to design, program, and understand computer systems.
2. A transistor acts as an electronic switch. When a small electrical signal is applied to its control terminal, it can either allow a large amount of current to flow through it (corresponding to the "on" state of the wire) or block the current flow (corresponding to the "off" state of the wire), enabling the computer to perform binary - based logic operations.
3. Computers need many transistors because each transistor can perform only simple operations like switching or basic logic functions. To perform complex tasks such as running operating systems, executing programs, and handling data, a large number of transistors are combined to form complex circuits like logic gates, memory cells, and processing units.

Answer:

1. Computers use abstraction for electricity in wires to simplify complex electrical processes and focus on logical operations by representing electrical states as binary values.
2. A transistor acts as an electronic switch, allowing or blocking current flow to determine if a wire is "on" or "off".
3. Computers need many transistors as each can perform only simple operations and complex tasks require combinations of numerous transistors to form complex circuits.
