Estimate the record length and number of records of the physical file for storing 100 logical messages, where the message size is 4096 bytes and the number of segments of a logical message is 3. One record should store one logical message. The sector length of the file system is 512 bytes.

• Record length=((4096 + 976 + 8 x 3 + 36 x 1) / 1) / 512 x 512 = 5632
• Number of records =100 x 1 + 1=101

: Rounded up to the nearest integer.
