This task aims to spotlight on data compression and data rate. Answer the following questions: Two students are trying to download two files from the internet, student (A) is downloading File (A) which has the size of 110 MB while student (B) is trying to download the second one, file (B), which has the size of 50 MB. Student (A) is using internet of download speed of 400 Kbps while student (B) is using internet of download speed of 200 Kbps. 1. How long does it take to download file (A) by student (A), express your answer in seconds and minutes? 2. How long does it take to download file (B) by student B, express your answer in seconds and minutes? 3. Which student will download his file first? 4. Both students finished downloading them and decided to compress the files before storing them to CD. Student (A) compressed the file to 40 MB file, what is the compression ratio? 5. Student (B) used the same application which was used by student (A) to compress his file, what is the size of the compressed file of student B?

On a 16 GB hard disk drive (HDD), each cluster consists of 32 sectors and each sector has a fixed size of 512 bytes. A text file with a size of 150,000 bytes is to be stored. a. i.How many clusters does the text file take up in memory? ii.What is the size of the slack space, in bytes, once the file has been stored?
Part A: Using a writing speed of 800 Mbits/s, how long would it take to store a 40 GB raw video file on a blue ray disk? How small would the 40 GB raw video file become if it is compressed with a compression ratio of 8. Part B: Taking the speed of the radio signal as 3×100 meters per second, calculate the time taken for a signal to reach a GPS receiver from a GPS satellite at a position 20000 km distant from the receiver. Assume that the speed of the signal is unchanged over the whole path length. Express your answer in milliseconds.

Where does fragmentation come in? Differentiate between internal and external fragmentation.
Suppose a file system uses the Block bitmap to indicate allocation status of blocks in the File Contents region, and the FCB bitmap to indicate usage status of FCBs. The Block bitmap uses N blocks, whereas the FCB bitmap uses 1 block. (a) If the File Contents region is 32Gbytes and the block size is 4Kbytes, how many blocks (N) should be allocated to the Block bitmap? (b) Also, if each FCB is 128 bytes, how many blocks should be allocated to the FCB table (A table which stores FCBs)? (2) [ ts] Inode Structure In an i-node based file system implementation, the i-node typically stores 12 direct block pointers, one 1-indirect block pointer, one 2-indirect block pointer, and one 3-indirect block pointer. Recall that an indirect block is a disk block storing an array of disk block addresses (i.e. pointers). The pointers in a 1-indirect block point to disk blocks that store file data. The pointers in a 2-indirect (or 3-indirect) block point to other 1-indirect (or 2-indirect) blocks. Suppose…
