What are the main purposes of industrial computing, input devices, system software, and the E12 series? How do serial and parallel transmissions differ?

Here are the answers to the questions:

1. The main purpose of industrial computing is to

   • B. control and monitor industrial processes Industrial computing systems are designed to automate, monitor, and control machinery and processes in industrial environments.

2. A device used to enter data into a computer system is a/an

   • C. Scanner A scanner is an input device that converts physical documents or images into digital data for a computer. A plotter, speaker, and projector are output devices.

3. System software is mainly responsible for

   • B. managing hardware resources System software, such as an operating system, manages the computer's hardware and software resources, providing a platform for application software to run.

4. The number of resistors per decade in the E12 series is

   • A. 12 The "E" in E-series stands for "preferred values," and the number (e.g., 12 in E12) indicates how many standard values are available per decade (a factor of 10).

5. A device driver is required so that the operating system can

   • A. detect and control connected devices A device driver is a software program that allows the operating system to communicate with and operate a specific hardware device.

6. Serial transmission differs from parallel transmission because serial transmission

   • A. sends bits one after another on a single line Serial transmission sends data bits sequentially over a single communication channel, while parallel transmission sends multiple bits simultaneously over multiple channels.

7. In a relational database, a record corresponds to a

   • B. complete row in a table In a relational database, a record (or tuple) is a single entry in a table, representing a complete set of related data, which is stored as a row.

I cannot answer question 8 as the options are not visible in the image.
