Primary storage refers to your RAM it is internal storage.

Secondary storage is any storage that is not the primary storage that permanently stores data. Examples are hard drive, tape disk drive, floppy disk drive  and compact disk drive. 

Off-line storage refers to any device that stores data that is not permanently attached to the computer. Example flash drives, The data remains on the storage device and can be connected to a different computer.

Which two statements are true about algorithms?
DENIUS [597]

Answer:

I. Algorithms can be written using pseudocode.

II. Algorithms can be visualized using flowcharts.

Explanation:

An algorithm can be defined as a standard formula or procedures which comprises of set of finite steps or instructions for solving a problem on a computer. The time complexity is a measure of the amount of time required by an algorithm to run till its completion of the task with respect to the length of the input.

The two statements which are true about algorithms are;

I. Algorithms can be written using pseudocode. A pseudocode refers to the description of the steps contained in an algorithm using a plain or natural language.

II. Algorithms can be visualized using flowcharts. A flowchart can be defined as a graphical representation of an algorithm for a process or workflow.

Basically, a flowchart make use of standard symbols such as arrows, rectangle, diamond and an oval to graphically represent the steps associated with a system, process or workflow sequentially i.e from the beginning (start) to the end (finish).

Define a function calc_pyramid_volume with parameters base_length, base_width, and pyramid_height, that returns the volume of a
Sever21 [200]

The missing segment of the code illustrates the use of functions.

Functions are also referred to as <em>procedures or methods</em>; they are set of instructions that act as one.

The code segment that complete the code in the question is as follows:

<em>def calc_pyramid_volume(length, width, height): </em>

<em>    baseArea = length * width </em>

<em>    Volume = baseArea * height * 1/3 </em>

<em>    return Volume</em>

<em />

<em />

The first line of the code segment declares the function itself

<em>def calc_pyramid_volume(length, width, height):</em>

Then, the base area of the pyramid is calculated

<em>    baseArea = length * width</em>

Then, the volume of the pyramid is calculated

<em>    Volume = baseArea * height * 1/3</em>

Lastly, the volume is returned to the main method

<em>    return Volume</em>

So, the complete code (without comments) is:

<em>def calc_pyramid_volume(length, width, height): </em>

<em>    baseArea = length * width </em>

<em>    Volume = baseArea * height * 1/3 </em>

<em>    return Volume </em>

<em>     </em>

<em>length = float(input()) </em>

<em>width = float(input()) </em>

<em>height = float(input()) </em>

<em>print('Volume for', length, width, height, "is:", calc_pyramid_volume(length, width, height))</em>

<em />
