Network Monitoring

The term network monitoring describes the use of a system that always monitors a computer network for slow or failing systems and that notifies the network administrator in case of outages via email, pager or other alarms. It is a subset of the functions occupied in network management.

While an interruption detection system monitors a network for threats from the outside, a network monitoring system monitors the network for troubles due to overloaded and/or crashed servers, network connections or other devices.

usually measured metrics are response time and availability (or uptime), although both consistency and reliability metrics are starting to increase popularity.Status request failures, such as when a connection cannot be established, it times-out, or the document or message cannot be retrieved, usually produce an action from the monitoring system. These actions vary: an alarm may be sent out to the resident (SMS, email,...) sysadmin, automatic failover systems may be activated to remove the disturbed server from duty until it can be repaired, etcetera.Monitoring the performance of a network uplink is also known as network traffic measurement, and more software is listed there.

Linux is a computer operating system like unix,windows etc.. Linux is one of the most famous examples of free software and open source development; its underlying source code can be freely modified, used, and redistributed by anyone.The Linux kernel was first released to the community on 17 September 1991, for the Intel x86 PC architecture. The kernel was enlarged with system utilities and libraries from the GNU project to create a usable operating system, which later led to the alternate term GNU/Linux.Linux is now packaged for different uses in Linux distributions, which contain the sometimes customized kernel along with a variety of other software packages tailored to different requirements.

Inkjet Printer

Inkjet printers are a type of computer printer that operates by propelling minute droplets of liquid ink onto paper. They are the most general type of computer printer for the general consumer due to their low cost, high quality of output, capability of printing in vivid color, and ease of use

In the personal and small business computer market, inkjet printers presently predominate. Inkjets are usually cheap, quiet, reasonably fast, and many models can produce high quality output. Like most modern technologies, the present-day inkjet has built on the progress made by many earlier versions. Among many contributors, Epson, Hewlett-Packard and Canon can claim a substantial share of credit for the growth of the modern inkjet. In the worldwide consumer market, four manufacturers account for the majority of inkjet printer sales: Canon, Hewlett-Packard, Epson, and Lexmark.
