1.1.1 Scope
This standard defines Ethernet local area, access and metropolitan area networks. Ethernet is specified at
selected speeds of operation; and uses a common media access control (MAC) specification and
management information base (MIB). The Carrier Sense Multiple Access with Collision Detection
(CSMA/CD) MAC protocol specifies shared medium (half duplex) operation, as well as full…
1 Scope
1 This document specifies requirements for implementations of the C++ programming language. The first such
requirement is that they implement the language, so this document also defines C++. Other requirements
and relaxations of the first requirement appear at various places within this document.
2 C++ is a general purpose programming language based on the C programming language as…
