• A technique also know as "wireless cable", that transmits analog or digital video over a range of 30 miles.
• A wireless cable system capable of being encoded for pay-per-view and subscriber services.
• Terrestrial microwave system used to distribute high-bandwidth services to end-users at homes and offices. Advantage of MMDS over satellite-based services is in its ability to include local content programming.

NETWORK ARCHITECTURE

• The communication equipment, protocols and transmission links that constitute a network, and the methods by which they are arranged.
• Set of design principles defining the protocol, functions and logical components of a network and how they should perform.
• A formalized definition of the structure and protocols of a computer network.
• The basic layout of a computer and its attached systems, such as terminals and the paths between them.
• The underlying structure of a computer network, including hardware, functional layers, interfaces, and protocols, used to establish communication and ensure the reliable transfer of information. Network architectures are designed to provide both philosophical and physical standards for the complexities of establishing communications links and transferring information without conflict.
• The types and characteristics of the network components; for example, routers, switches, cables, and how they are connected.

• Two or more devices (or people) that communicate with each other and share resources.
• This is the inter- or intra-exchange of services or information between different individuals, groups, companies, or institutions.

NOC
Network Operations Center .

• A place from which a telecommunications or data network is supervised, monitored, and maintained.
• Is the organization responsible for the day-to-day operations of the Internet's component networks.
• Also called a datacenter. An NOC is a physical center from where networks are managed. Typically, a NOC/datacenter has hundreds or even thousands of Web servers with multiple connections to the backbone, and power backup systems.

Novell, Unix, Linux, SCO, Windows

• A computer operating system (software) that is designed direct the overall activity of workstations, personal computers, and terminals that are connected via a network.
• Operating system designed to pass information and communicate between more than one computer.
• Network operating systems are usually in two parts; server and client/requester. The requester puts the workstation on the server machine and makes disks, software, ports and other facilities available to a node on request. Each device's services requested by a PC are accessed via the requester software.
• The software that controls the operation of the network. A NOS enables users to communicate and to share files and peripherals.
• Software that controls the operations of a network; controls the attached computer systems, peripherals, and communication between them.

• When all types and brands of hardware and software equipment are interchangeable and able to function together.
• The ability to run applications on a range of leading hardware, database platforms, and migrate from one to another, without changing the look and feel of your applications.

• Largest software company whose primary business is database products.
• Historically, Oracle has targeted high-end workstations and minicomputers as the server platforms to run its database systems.
• Its relational database was the first to support the SQL language, which has since become the industry standard.
• Oracle is a relational database management system (RDBMS) developed and copyrighted by the Oracle Corporation.

OSS
Operations Support System

• Network management system supporting a specific management function, such as alarm surveillance and provisioning, in a carrier network. Many OSSs are large centralized systems running on mainframes or minicomputers.
• Methods and procedures that support the daily operation of a carrier's infrastructure, including order processing, equipment assignment, etc.

PAGING

• Wireless text messaging services.
• A one-way alert or alphanumeric message service. Messages are normally left via a bureau with a human or automatic operator.

PROGRAMMING LANGUAGE
Pascal, C, Per,l Java, BASIC, COBOL, C++, Fortran

• In essence, programming languages are translators that take words and symbols and convert them to binary codes that the CPU can understand.
• A computer, human-created language used to write instructions for a computer.
• The "Rosetta Stone" for computers. Programming language is what translates instructions from humans to computers.
• A language designed for programming computers.
• It is a set of syntactic and semantic rules used to define computer programs.

QoS
Quality of Service

• A guarantee of timely and safe delivery of packets over a network.
• Measure of performance for a transmission system that reflects its transmission quality and service availability.
• On the Internet and in other networks, QoS (Quality of Service) is the idea that transmission rates, error rates, and other characteristics can be measured, improved, and, to some extent, guaranteed in advance.
• QoS is of particular concern for the continuous transmission of high-bandwidth video and multimedia information. Transmitting this kind of content dependably is difficult in public networks using ordinary "best effort" protocols.

• A communications device between networks that determines the best path between them for optimal performance.
• A device that determines the next network point to which a data packet should be forwarded enroute toward its destination. The router is connected to at least two networks and determines which way to send each data packet based on its current understanding of the state of the networks it is connected to. Routers create or maintain a table of the available routes and use this information to determine the best route for a given data packet.
