That should be the replace function which performs word replacements in documents.

<span>Not a valid IPv6 address
A valid IPv6 address consist of 8 groups of 4 hexadecimal numbers separated by colons ":". But that can make for a rather long address of 39 characters. So you're allowed to abbreviate an IPv6 address by getting rid of superfluous zeros. The superfluous zeros are leading zeros in each group of 4 digits, but you have to leave at least one digit in each group. The final elimination of 1 or more groups of all zeros is to use a double colon "::" to replace one or more groups of all zeros. But you can only do that once. Otherwise, it results in an ambiguous IP address. For the example of 2001:1d5::30a::1, there are two such omissions, meaning that the address can be any of
2001:1d5:0:30a:0:0:0:1
2001:1d5:0:0:30a:0:0:1
2001:1d5:0:0:0:30a:0:1
And since you can't determine which it is, it's not a valid IP address.</span>
Answer:
Root
Explanation:
Linux is an open source operating system which receives command from the user and communicates with the hardware, and in Linux the root directory is the top level directory that contains all other directory, it is not recommended to create files and folders in the root directory because the commands the user enters may change files that the operation system may depend on for usage.
Answer and Explanation:
The compression rate says by how much the text was compressed from the original as a percentage. Don't forget that the compressed version of the text is the compressed text size + dictionary size.
From the given picture:
compressed text size = 17 bytes
dictionary size = 26 bytes
compressed text size + dictionary size = 17 + 26 = 43 bytes
original test size = 58 bytes
compression rate as percentage = (43 / 58) * 100 = 74.14% ( rounded to two decimal )
Space savings = 100 - compression rate
= 100 - 74.14 = 25.86%
Is this a "good" compression rate? Why or why not?
Compression data is a heuristic problem. It’s hard to say the exact compression rate that is good or bad. If you feel satisfied by ~ 26% of compression, then it is a good compression rate.
The compression rate above frees up 26% space for you, so that you can put additional information
without losing information. In that way it is a good compression rate.
