The System Management Unit (SMU) is an advanced internal subsystem introduced in late 2004 with the iMac G5 and Power Mac G5 series computers. It manages the functions previously governed by the PMU (Power Management Unit) as well as additional cooling functions.
In 2017, an online poll of social media users in the UK was reported to show that PowerPoint "remains as popular with young tech-savvy users as it is with the Baby Boomers," with about four out of five saying that "PowerPoint was a great tool for making presentations," in part because "PowerPoint, with its capacity to be highly visual, bridges ...

In computing, a presentation program (also called presentation software) is a software package used to display information in the form of a slide show.

The systems formalised the concept of a collection of related units called a coherent system of units. In a coherent system, base units combine to define derived units without extra factors. [4]: 2 For example, using metre per second is coherent in a system that uses metre for length and second for time, but kilometre per hour is not coherent.
Hardware derived its name from the fact it is hard or rigid with respect to changes, whereas software is soft because it is easy to change. Hardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware.
Systems can be isolated, closed, or open. A system is a group of interacting or interrelated elements that act according to a set of rules to form a unified whole. [1] A system, surrounded and influenced by its environment, is described by its boundaries, structure and purpose and is expressed in its functioning.
The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. A CU typically uses a binary decoder to convert coded instructions into timing and control signals that direct the operation of the other units (memory, arithmetic logic unit and input and output devices, etc.).
An ICD is the umbrella document over the system interfaces; examples of what these interface specifications should describe include: The inputs and outputs of a single system, documented in individual SIRS (Software Interface Requirements Specifications) and HIRS (Hardware Interface Requirements Specifications) documents, would fall under "The Wikipedia Interface Control Document".
