If there are twenty 256-byte records per block, each block holds 5,120 bytes of data, and uses 500+5,120, or 5,620 bytes of track space when non-data overhead is taken into account. a) Find number of blocks&records that can fit on a 50,000 byte track. b) If there are fifty 256-byte records per block, each block holds 12,800 bytes of data, and uses 12,800+500 bytes of track space, find number of blocks&records that can fit on a 50,000 byte track. Analyze the connection between block factor and disk storage usage
