Answer:
Total time = 190 ms
Explanation:
The requests missing in question are:
Requests ( A, 80) , (B,75) , (C,82) , (D,90) , (E,45)
Number of movements = | 70 - 45 | + | 45 - 0 | + | 0 - 75 | + | 75 - 80 | + | 80 - 82 | + | 82 - 90 |
= 35 + 45 + 75 + 5 + 2 + 8
= 70 + 80 + 10
= 160
Time taken for seek = 160 * 1 ms = 160 ms
Time taken for servicing request = Number of tracks * Time for each track = 5*6 = 30
Total time = 160 + 30 = 190 ms.
Answer:
The appropriate answer will be "Doctype
".
Explanation:
- Probably the DOCTYPE would not be a component or perhaps an HTML tag. It allows the app or developer to know how and where to view the text, by suggesting the HTML (and perhaps another XML language) edition or specification would be used.
- A document type specification, or DOCTYPE, seems to be a guideline associating a specific SGML as well as an XML document with either the concept of a document.
