A hard disk has four surfaces (that's top and bottom of two platters). Each track has 2,048 sectors and there are 131,072 (217)
marysya [2.9K]

Answer:

128 GB

Explanation:

Here, we are interested in calculating the total capacity of the disk.

From the question, we can identify the following;

Number of surfaces = 4

Tracks per surface = 131,072

Number of sectors = 2,048

Each Block size = 512 bytes

Mathematically;

Total data capacity of the disk = no of tracks * no of sectors * block size

= 131,072 * 2048 * 512 bytes

= 2^17 * 2^11 * 2^9 bytes = 2^37 bytes

1 GB = 2^30 bytes

So 2^37 = 2^7 * 2^30

= 128 GB

How many bits does it take to store a 3-minute song using an audio encoding method that samples at the rate of 40,000 bits/secon
blondinia [14]

Answer:

115200000 bits

Explanation:

Given Data:

Total Time = 3 minute = 3 x 60 sec = 180 sec

Sampling rate = 40,000 bits / sample

Each sample contain bits = 16 bits /sample

Total bits of song = ?

Solution

Total bits of song = Total Time x Sampling rate x Each sample contain bits

                             = 180 sec x 40,000 bits / sec x 16 bits /sample

                             = 115200000 bits

                             =  115200000/8 bits

                             = 14400000 bytes

                             = 144 MB

There are total samples in one second are 40000. Total time of the song is 180 seconds and one sample contains 16 bits. so the total bits in the song are 144 MB.

Explanation:

A spreadsheet program is a computerized version of a paper accounting worksheet where everyone can easily use the sheet according to their need. For example, a spreadsheet can be used as a data entry sheet, as arithmetic operations. Data entry in paper accounting was done manually with paper whereas spreadsheet has cells in it to record the entries. Similarly, other operations such as recording the data, performing analytical operations were part of old system and these are now used in spreadsheet as a basic function.  In short, the spreadsheet is a very friendly application where values can be analyzed, stored, and modified as per requirements. These all defined tasks are part of paper based accounting now done using computer program.
