Group of answer choices.
A. Computing devices translate digital to analog information in order to process the information.
B. Computing devices are electronic.
C. The CPU processes commands.
D. The memory uses binary numbers
Answer:
A. Computing devices translate digital to analog information in order to process the information.
Explanation:
Computing is the process of using computer hardware and software to manage, process and transmit data in order to complete a goal-oriented task.
The true statements about computers are;
I. Computing devices are electronic: the components and parts which makes up a computer system are mainly powered by a power supply unit and motherboard that typically comprises of electronic components such as capacitors, resistors, diodes etc.
II. The CPU processes commands: the central processing unit (CPU) is responsible for converting or transforming the data from an input device into a usable format and sent to the output device.
III. The memory uses binary numbers: computer only understand ones and zeros.
Answer:
Neither A nor B
Explanation:
<em>Reserve capacity</em> is the number of minutes that a new, fully charged battery can discharge continuously and maintain a terminal voltage equal to or greater than 1.75 volts per cell.
<em>An ampere-hour </em>is an electric charge unit and its abbreviation is Ah.
It measures the amount of electric charge flowing through a battery in the case that amount supplies a current of 1 amp for 1 hour.

Answer:
Yes. Pseudocode is an improvement over the IPO chart because it lays out the sequence of steps for a particular program
Explanation:
The input–process–output (IPO) chart is a widely used approach in systems analysis and software engineering for describing the structure of an information processing program or other process. The chart has three components (Input, Process and Output), and you write the description of each component in plain English, not code or mathematical formulas.
Pseudocode is a procedure for solving a problem in terms of the actions to be executed and the order in which those actions are to be executed.
Pseudocode is an improvement over the IPO chart because it shows the step by step sequence to be followed by a particular program unlike the IPO chart which just break the program into Input, Process and Output.
