Final answer:
The answer to the question is 'Computer scientists and engineers'. They play vital roles in creating and maintaining the computing systems that are integral to technological solutions, and they work at major tech companies.
Step-by-step explanation:
The correct answer to fill in the space provided is Computer scientists and engineers. These professionals are responsible for designing and operating the software, inputting data, constructing the hardware, and maintaining its operation. Computer scientists develop programs for various applications, such as aiding those with physical challenges through artificial limb control or vehicle operation. Engineers, on the other hand, look at computing on a physical level where electronic changes take place in the hardware. Both groups of specialists work together to create automated systems that are used in everyday life and can often be found in companies like Microsoft, Apple, and Hewlett Packard.
