Question: OS Given a magnetic tape data storage system with Inter Record Gap (IRG) length of 1 cm, where each data record requires a tape length

OS

Given a magnetic tape data storage system with Inter Record Gap (IRG) length of 1 cm, where each data record requires a tape length of 0.2 cm. Each file starts and ends with a data block and there exits gaps between these blocks.

(i).

Calculate the length of the tape required to keep 200 records using 10 records per block.

(ii).

Calculate the length of the tape required to keep 200 records using 25 records per block.

(iii).

Calculate the length of the tape required to keep 200 records using 50 records per block.

(iv).

Distinguish the effect of the 4(b)(i), 4(b)(ii) and 4(b)(iii), towards small- sized files (with 15 records average for each file).
