Net neutrality is the practice of keeping Internet service providers from offering tiered service and controlling the ability to block out competition by restricting certain pipelines within the Internet. By blocking these pipelines, the provider creates an unfair transfer of packets across the Internet, diminishing the quality of service.
Linux Gazette carries a regular column called Layer 8 Linux Security. [9] Layers 8, 9, and 10 are sometimes used to represent individuals, organizations, and governments for the user layer of service-oriented architectures. See OSI User Layers figure for details. User-in-the-loop is a serious concept including Layer 8 as a system-level model.
Total Delivered Cost (TDC) is the amount of money it takes for a company to manufacture and deliver a product. Its components are: Its components are: Total Manufacturing Cost : Costs incurred up to and inclusive of the production of finished and wrapped pallets or unit loads , fit for introduction into the warehousing and distribution chain .
A cost estimate is the approximation of the cost of a program, project, or operation. The cost estimate is the product of the cost estimating process. The cost estimate has a single total value and may have identifiable component values. A problem with a cost overrun can be avoided with a credible, reliable, and accurate cost estimate. A cost ...
A service-level agreement can track multiple performance metrics. In this context, these metrics are called service level indicators (SLIs). The target value of a given SLI is called a service-level objective (SLO). In IT-service management, a common case is a call center or service desk. SLAs in such cases usually refer to the following SLIs:
If there are no intermediaries then this is known as a zero-level distribution system or direct marketing. A level one (sometimes called one-tier) channel has a single intermediary. A level two (alternatively a two-tier) channel has two intermediaries, and so on. This flow is typically represented as being manufacturer to retailer to consumer ...

At each level N, two entities at the communicating devices (layer N peers) exchange protocol data units (PDUs) by means of a layer N protocol. Each PDU contains a payload, called the service data unit (SDU), along with protocol-related headers or footers. Data processing by two communicating OSI-compatible devices proceeds as follows:
