A workstation operating system, such as Windows 10 or macOS, is most likely used to provide the graphical user interface (GUI) for a workplace employee. These operating systems are designed for daily use by employees, providing a user-friendly environment for running applications, accessing files, and performing tasks.

A. Hypervisor is used for managing virtual machines, not for providing a GUI for end users.

B. Firmware operates at a lower level, controlling hardware, and does not provide a user GUI.

C. Server operating systems manage network resources and services but are not typically used directly by employees for everyday tasks.

Float is a data type that can store decimal or fractional numbers, such as 3.14, 0.5, or -2.75. Float would be the best data type to use for storing monetary values because monetary values often involve decimals, such as $1.99, 0.25,or-5.50. Integer is a data type that can only store whole numbers, such as 1, 0, or -2. Integer would not be suitable for storing monetary values that have decimals. The other options are not data types that can store numerical values.

 Password complexity and password history are two practices that are being employed by the IT department to establish a new password policy for employees. Password complexity is the requirement that passwords must contain a combination of different types of characters, such as letters, numbers, and symbols. Password complexity makes passwords harder to guess or crack by attackers. Password history is the record of the previous passwords used by a user. Password history prevents users from reusing the same passwords over and over again, which reduces the risk of compromise. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 208.

Processing is the process that is being performed by the GPU on the graphics card. A GPU (graphics processing unit) is a specialized processor that is designed to handle graphics-related tasks, such as rendering images, videos, animations, or games. A GPU can perform parallel computations faster and more efficiently than a CPU (central processing unit), which is the main processor of a computer. A GPU can be integrated into the motherboard or installed as a separate component on a graphics card. A graphics card is an expansion card that connects to a slot on the motherboard and provides video output to a display device, such as a monitor or projector. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 35.
