Why did the IEEE 802 committee split into smaller subcommittees? How are the subcommittees identified?

What will be an ideal response?

Although the original intent of the IEEE in forming the 802 committee was to define a single, universal standard for networking, the IEEE discovered that it needed multiple standards, so it split the 802 committee into smaller subcommittees with names like 802.3 or 802.11. Each of these subcommittees worked on developing standards for one particular area of networking.
