a)Green computing, also called green technology, is the environmentally responsible use of computers and related resources. Such practices include the implementation of energy-efficient central processing units (CPUs), servers and peripherals as well as reduced resource consumption and proper disposal of electronic waste (e-waste).
b) i)Develope a sustainable green computing plan.
ii)Recycle.
iii)Make environmentally sound purchase decisions.
iv)Reduce paper consumption.
v)Converse energy.

PART B:
a) 1) In computer networks and telecommunications, a dedicated line is a communications cable or other facility dedicated to a specific application, in contrast with a shared resource such as the telephone network or the Internet.
2)Integrated Services for Digital Network (ISDN) is a set of communication standards for simultaneous digital transmission of voice, video, data, and other network services over the traditional circuits of the public switched telephone network. It was first defined in 1988 in the CCITT red book. Prior to ISDN, the telephone system was viewed as a way to transport voice, with some special services available for data. The key feature of ISDN is that it integrates speech and data on the same lines, adding features that were not available in the classic telephone system. There are several kinds of access interfaces to ISDN defined as Basic Rate Interface (BRI), Primary Rate Interface (PRI), Narrowband ISDN (N-ISDN), and Broadband ISDN (B-ISDN).
3)Digital subscriber line (DSL, originally digital subscriber loop) is a family of technologies that provide Internet access by transmitting digitaldata over the wires of a local telephone network. In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line (ADSL), the most commonly installed DSL technology. DSL service is delivered simultaneously with wired telephone service on the same telephone line. This is possible because DSL uses higher frequency bands for data. On the customer premises, a DSL filter on each non-DSL outlet blocks any high frequency interference, to enable simultaneous use of the voice and DSL services.
4)Fiber-To-The-Premises (FTTP) is a technology for providing Internet access by running fiber optic cable directly from an Internet Service Provider (ISP) to a user's home or business. It facilitates much faster speeds than dial-up and most coaxial cable Internet connections, and generally needs to be serviced less. It's also considered one of the most "future proof" types of Internet technology, since there are no foreseeable devices that could use more bandwidththan can be sent via fiber optic cables. Despite its benefits, it is difficult and expensive to install.
5)T-carrier, sometimes abbreviated as T-CXR, refers to one of several digital transmission systems developed by Bell Labs. T-carriers are used in North America, South Korea, and Kyoto.
6)Asynchronous Transfer Mode (ATM) is, according to the ATM Forum, "a telecommunications concept defined by ANSI and ITU (formerly CCITT) standards for carriage of a complete range of user traffic, including voice, data, and video signals". ATM was developed to meet the needs of the Broadband Integrated Services Digital Network, as defined in the late 1980s,[and designed to unify telecommunication and computer networks. It was designed for a network that must handle both traditional high-throughput data traffic (e.g., file transfers), and real-time, low-latency content such as voice and video.
