2. Need for Standards
•
make or break networking products
•
Interoperability
•
Vendor independence is designing or manufacturing
products.
•
Should have a common ground where manufacturer's
obey the standardization

3. List of Standards
•
There are several Standards, but most common ones
are
•
ISO (International organization of Standardization)
•
IEEE (Institute of Electrical and Electronic Engineers)

4. ISO
•
OSI Model is developed by ISO for Networking
•
ANSI is the member of ISO that develops standards
from programming language to Disk drives

5. IEEE
•
IEEE Society has more than 3 Lakh members
•
Computer Soceity of IEEE alone has more than 1 Lakh
members
•
