It was composed under the leadership of a noted Indian Sanskritist, V.S. Sukthankar.
 The elements considered:

 (i) They selected the verses that appeared common to most versions.
 (ii) There were several common elements in the Sanskrit versions of the story, evident in manuscripts found all over the subcontinent.
 (iii) When issues of social history were explored for the first by historians in the nineteenth and twentieth centuries, they tended to take these texts at face value-believing that everything that was laid down in these text was actually practiced.
 (iv) The studies indicated that the ideas contained in normative Sanskrit texts were, on the whole, recognized as authoritative: they were also questioned and occasionally even rejected.

The huge obstacle in nation building at the time of India’s independence was to shape a nation that was united, yet accommodative of the diversity in our society. India was a land of continental size and diversity. Its people spoke different languages and followed different culture and religions. At that time it was widely believed that a country full of such kinds of diversity could not remain together for long.

Historians have diverse opinions regarding the existence of rulers in the Harappan society. While some historians believe that the Harappan society had no rulers, other claim that there were rulers. Historians who believe in the existence of rulers claim that the elaborate town planning and use of same weights and measures across the IVC indicate that it were rulers who set standards and implemented such complex decisions.

Functions that were probably performed by the rulers of the Harappan society were:

• During excavations, archaeologist have found the remains of planned Harappan cities. The bricks used on making houses were of standardized ratio and were used in all Harappan cities. There was a well planned drainage system in place. There are indications of complex decisions being taken and implemented in Harappan society. There was a uniformity of Harappan artefacts such as pottery, seals, weight and measures. Thus, one of the functions of the ruler was to set guidelines for making houses and other commodities.
• In the IVC, settlements were strategically set up in specific locations for various reasons. One such case is the setting up of settlements near the source of raw materials so that it is easy to produce various ornaments and craft products. Thus, another function of the ruler could be of maintain production centers and chalking out strategies to procure raw materials from distance lands.
• Another function of the ruler may have to mobilise the work force for procuring bricks and required materials for constructing houses and other buildings.
• The Harappan established flourishing trade relations with far off lands like Oman, Mesopotamia and Bahrain. The presence of uniformity in seals, weights and measures indicate that the rulers looked after the economy of their territory.

Advantages of Network:
These are main advantages of Computer Networks:

1. Central Storage of Data –
   Files can be stored on a central node (the file server) that can be shared and made available to each and every user in an organization.
2. Anyone can connect to a computer network –
   There is a negligible range of abilities required to connect to a modern computer network. The effortlessness of joining makes it workable for even youthful kids to start exploiting the data.
3. Faster Problem solving –
   Since an extensive procedure is disintegrated into a few littler procedures and each is taken care of by all the associated gadgets, an explicit issue can be settled in lesser time.

Disadvantages of Network:
These are main disadvantages of Computer Networks:

1. It lacks robustness –
   If a PC system’s principle server separates, the whole framework would end up futile. Also, if it has a bridging device or a central linking server that fails, the entire network would also come to a standstill. To manage these issues, gigantic systems ought to have a ground-breaking PC to fill in as document server to influence setting to up and keeping up the system less demanding.
2. It lacks independence –
   PC organizing includes a procedure that is worked utilizing PCs, so individuals will depend a greater amount of PC work, rather than applying an exertion for their jobs that needs to be done. Beside this, they will be subject to the primary document server, which implies that, in the event that it separates, the framework would end up futile, making clients inactive.
3. Virus and Malware –
   On the off chance that even one PC on a system gets contaminated with an infection, there is a possibility for alternate frameworks to get tainted as well. Infections can spread on a system effectively, in view of the between availability of different gadgets.4. Lack of Independence
4. Cost of network –
   The expense of executing the system including cabling and equipment can be expensive.
