SNMPSimple Network Management Protocol is the Internet standard protocol developed to managenodes (servers, workstations, routers, switches, hubs, etc.) on IP networks. It enables networkadministrators to manage network performance, find and solve network problems, and planfor network growth. SNMP works by sending Protocol Data Units (PDUs) messages todifferent parts of a network. Agents, SNMP-compliant devices, store data about themselvesin Management Information Bases (MIBs) and return this data to the SNMP requesters.Square pixelsSee Aspect ratio – of pixelsSRAMSee RAMSSDSee Flash MemoryStandard platformA computer and operating system built for general-purpose use. It cannot be used onits own but must be fitted with any, or many, of the very wide range of specific applicationsoftware and additional hardware packages available. For example, the same standardplatform may be used for accounting, word processing and graphics but each runs froma different software applications package and may need special hardware.SThe term has become somewhat confusing in that a standard platform can be anythingfrom a PC to a super computer. Also some applications are mutually exclusive – whenthe computer’s hardware is configured for one it has to be re-configured to run another.It is then arguable whether this is still a standard platform or has it metamorphosed intoa dedicated system?Standards (television)A digital television standard defines the picture format (pixels per line and active lines),vertical refresh rate and whether the vertical scan is interlaced or progressive.
