True. An encryption scheme doesn't care what it is encrypting, be it compressed or uncompressed.

Note that an encrypted file will look like random data to most compression algorithms, so it makes sense to first compress, then encrypt, to get the maximum efficiency from the compression.

The following pseudocode is an example of ____.do stepAdo stepBif conditionC is true thendo stepDelsedo stepEendifwhile conditio
rewona [7]

Answer:

Option d pretest

Explanation:

Given the pseudocode:

  1. do stepA
  2. do stepB
  3. if conditionC is true
  4. then do stepD
  5. else
  6. do stepE
  7. end if
  8. while conditionF is true
  9. do stepG
  10. end while

The pseudocode above shows that there is a pretest before some codes are executed. For example, line 3 check if condition is true then only execute stepD otherwise execute stepE. Line 8 check if conditionF is true then repeatedly execute stepG. These are examples of pretest a condition will must be met (pretest passed) before a block of codes can be executed. This pretest can be seen in if-else statements and also the while condition.

The component that allows you to make a paper-based copy of a body of text is the _____.
ANTONII [103]
The correct answer is: Scanner

The scanner is a piece of technology which unlike the printer is an input device which basically scans the top-view of any flat surface (usually paper but is definitely not limited to it) introduced in its effective range using light. The data scanned is then transfered to the Central Processing Unit for futher processing. The processed image can then be outputted and seen on the monitor's display. Once available for printing, the Central Processing Unit will just send the processed image into the printer ad voila, your scanned image is now printed in a piece of paper!

Today, scanners come with printers as a bundle. It is a perfect combination since the printer will just print the image anyway.

Which operating system function has a steeper learning curve and can potentially break the system without careful use of its ope
grandymaker [24]

Answer:

4. Command line interface (CLI)

Explanation:

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.

A Command line interface (CLI) refers to a text-based user interface that allow users to operate a software application or program, as well as manage and execute operating system functions by typing standard line of commands into the text-based user interface with a real-time response.

Basically, the CLI is solely text-based and as such requires a thorough knowledge and understanding of global commands, as well as administrative privileges in some cases.

<em>Hence, the operating system function which has a steeper learning curve (more difficult to learn) and can potentially break the system without careful use of its operations is the Command line interface (CLI). </em>
