A small hard drive typically has only one platter, but each side of it has a magnetic coating. Bigger drives have a series of platters stacked on a central spindle, with a small gap in between them. The platters rotate at up to 10,000 revolutions per minute so the read-write heads can access any part of them.

I think putting hyperlink in essential pages is a good idea as it may guide a user
If you want the best possible print, you need to upload the best quality digital file. Sometimes photos might look just fine when you look at them on your computer screen, and you might wonder what’s up with us when we say we can’t print them. Photos that don’t have sufficient resolution will look all blurry and pixilated (blocky with jagged edges) when printed.
Answer:
A Caesar Cipher is a basic encryption type.
Explanation:
Its implementation is very easy and straightforward. It uses a one-to-one of characters in a character set. The input needed is the plain-text message and the encryption number.
For example, using the character set A-Z, encrypting the text CS IS COOL using the key of 3 generates FV LV FRRO. What has been done here is to take each character in the plain-text message and move it by "encryption number steps" in the character set.
Answer:
448 strings
Explanation:
Each bit string can be filled by two ways either 0 or 1. If the bit strings of length contain the substring '111000' we therefore need a substring of length 6.
The selection of bits starts from the 1st bit to 7th bit enclosing the substring 111000 and ensuring that the length 6 are all filled. So, there will be 7 ways to contain this substring.
The total ways to contain this substring = 7*2^6 =448
Therefore 448 strings of length 12 contain the substring '111000'.
