Consider a file system on a disk that has both logical and physical block sizes of 512 bytes. Assume that the information about each file is already in memory (i. e. the file control block and its metadata are in memory but everything else (such as the data or index blocks) are not). For each of the three allocation strategies (contiguous, linked, and indexed), answer these questions:

(a) How is the logical-to-physical address mapping accomplished in this system? (For the indexed allocation, assume that a file is always less than 512 blocks long.)
Contiguous:
Linked:
Indexed:

(b) If we are currently at logical block 10 (i. e. the last block accessed was block 10) and want to access logical block 4, how many physical blocks must be read from the disk?

What computer network component allows data transfers from one computer to another through a telephone line?

Write a full class definition for a class named player , and containing the following members: a data member name of type string .a data member score of type int .a member function called setname that accepts a parameter and assigns it to name . the function returns no value. a member function called setscore that accepts a parameter and assigns it to score . the function returns no value. a member function called getname that accepts no parameters and returns the value of name .a member function called getscore that accepts no parameters and returns the value of score .this is what i have, aparently this is wrong: class player{private: string name; int score; public: void player: : setname (string n){name =n; }void player: : setscore (int s){score = s; }string player: : getname (){return name; }int player: : getscore (){return score; }};

Why were most movies from the late 1890s until the early 1930s only filmed in black and white? there were only a few people who could afford the technology to produce color motion pictures back then. audiences did not want color motion pictures until later. the film used to make color motion pictures often overheated, which was a safety hazard, so it was generally not allowed. color films had to be hand-colored, frame by frame.
