Network management refers to the activities, methods, procedures, and tools that pertain to the operation, administration, maintenance, and provisioning of networked systems.
* Operation deals with keeping the network (and the services that the network provides) up and running smoothly. It includes monitoring the network to spot problems as soon as possible, ideally before users are affected.
* Administration deals with keeping track of resources in the network and how they are assigned. It includes all the "housekeeping" that is necessary to keep the network under control.
* Maintenance is concerned with performing repairs and upgrades - for example, when equipment must be replaced, when a router needs a patch for an operating system image, when a new switch is added to a network. Maintenance also involves corrective and preventive measures to make the managed network run "better", such as adjusting device configuration parameters.
* Provisioning is concerned with configuring resources in the network to support a given service. For example, this might include setting up the network so that a new customer can receive voice service.

Description:
MORE : More is a filter for paging through text one screenful at a time. This version is especially primitive. Users should realize that less(1) provides more(1) emulation and extensive enhancements.
LESS : Less is a program similar to more (1), but which allows backward movement in the file as well asforward movement. Also, less does not have to read the entire input file before starting, so with large input files it starts up faster than text editors like vi (1).
LS : List information about the FILEs (the current directory by default). Sort entries alphabetically if none of -cftuvSUX nor --sort. Mandatory arguments to long options are mandatory for short options too.
-a, --all do not ignore entries starting with . -l use a long listing format
CUDA (an acronym for Compute Unified Device Architecture) is a parallel computing architecture developed by NVIDIA. CUDA is the computing engine in NVIDIA graphics processing units or GPUs that is accessible to software developers through industry standard programming languages. Programmers use 'C for CUDA' (C with NVIDIA extensions), compiled through a PathScale Open64 C compiler, to code algorithms for execution on the GPU. CUDA architecture supports a range of computational interfaces including OpenCL and DirectX Compute.

A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by the customer or designer after manufacturing—hence "field-programmable". The FPGA configuration is generally specified using a hardware description language (HDL), similar to that used for an application-specific integrated circuit (ASIC) (circuit diagrams were previously used to specify the configuration, as they were for ASICs, but this is increasingly rare). FPGAs can be used to implement any logical function that an ASIC could perform. The ability to update the functionality after shipping, and the low non-recurring engineering costs relative to an ASIC design (not withstanding the generally higher unit cost), offer advantages for many applications.

About This Tutorial : In this tutorial you will learn how to implement power saving feature for a Network File Server (NAS), SAMBA, or a Media Server. For local and home backup solutions it is not necessary to keep the Network File Server Up and Running all the time. Anytime you need a backup, you can remotely turn it on and server will go to sleep whenever your file transferring is finished.
Happy Energy Saving !
Part 1: Enable Wake-On-Lan (WOL) feature It would let you turn on or awake a system from sleep state, by sending a magic packet to the network interface card.
Part 2: Enable Auto Sleep feature Turns off a system in absent of network activity.
Part 3: Sending the Magic Packet For WOL Turns on remotley the server by command or GUI.
