The operating system (OS) of an information system contains the software that executes the critical functions of the information system. The OS manages the computer's memory, processes, and all of its software and hardware. It allows different programs to run simultaneously and access the computer's memory, central processing unit, and storage. a. True
b. False

a. True

Explanation:

An information system (IS) can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.

Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information systems in order to perform their duties, functions or tasks and to manage their operations effectively. For example, all organizations make use of information systems for supply chain management, process financial accounts, manage their workforce, and as a marketing channels to reach their customers or potential customers.

Additionally, an information system comprises of five (5) main components;

1. Hardware.

2. Software.

3. Database.

4. Human resources.

5. Telecommunications.

An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.

This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.

On a related note, the software application that executes the critical functions of an information system (IS) are contained in its operating system (OS).

Basically, the computer's memory, processes, softwares and hardwares are typically being managed by the operating system (OS). Thus, an OS makes it possible for different programs to run simultaneously (more than one software program running concurrently) and access the computer's memory, central processing unit (CPU), and storage.
