A combination circuit would be needed for security because if you had a strait circuit if any one of those sensors or the keypad was ripped off the circuit will now let the flow of electricity be possible but with a combination circuit it helps eliminate that problem because even if on flow path is cut off, other paths are still available <span />

HACTEHA [7]

The answer is;

Current  

Voltage  

Power/Wattage  

Circuit

Water moving through pipes is like electricity flowing in a circuit. The flow of electricity is an actual flow of electrons. That movement of electrons is what is known as current. Think of current as the volume of water flowing through a water pipe. The electrons need some force or pressure to move, and so is water in a pipe. The voltage is that electromotive force; the pressure that pushes the electrons in a system. The power measured in Watts is the rate at which the energy is consumed. For the current to flow the circuit must be complete. Otherwise we cannot say that we have power if the circuit is not closed.

Which statement about broadcasting a slideshow online is true?
9966 [12]

Answer: PowerPoint has a free, built-in service for broadcasting online.

Explanation:

The statement that's true about the broadcast of a slideshow online is that PowerPoint has a free, built-in service for broadcasting online.

Option 1 is wrong as all transitions are not properly displayed to the audience when broadcasting online.

Option 2 is wrong as broadcasting as slideshow online is an option for most PowerPoint users.

Option 3 is wrong because when broadcasting online, third party desktop sharing software isn't necessarily an option and it isn't a must that it must be used.

Therefore, the correct option is 4.

The operating systems, and utility programs that perform system
Phantasy [73]

Answer:

System softwares.

Explanation:

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer how to perform a specific task and to solve a particular problem.

Basically, softwares are categorized into two (2) main categories and these are;

I. Utility software.

II. System software.

The operating systems, and utility programs that perform system maintenance and protection tasks such as error correction and backup are called system softwares.

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.

Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.

On the other hand, a utility software can be defined as a software application or program designed to add more functionality to a computer system, as well as to improve its performance efficiently. Some examples of commonly used utility tools in computer are file and folder backup tools, file management, antivirus, hard disk diagnostics, registry cleaner, network performance monitor, screensavers etc.
