Step-by-step explanation:
The field of computing has undergone significant changes since Dorothy first started at Langley.
When Dorothy first started, computers were large and expensive, filling entire rooms. They were primarily used by the military and businesses for record keeping and data processing.
However, over time, computers became smaller, more powerful, and more affordable. The development of digital computers and the invention of the transistor paved the way for the rapid evolution of computing technology. Today, we have powerful desktop and laptop machines that are capable of performing complex tasks.
