It is a collection of routers under the control of a single administrative authority and that uses a common Interior Gateway Protocol

The HELLO protocol uses time instead of distance to determine optimal routing. It is an alternative to the Routing

Information Protocol.

Distributed systems work in a network. They can share the network resources, communicate with each other.

A test plan is the master document that contains all details pertaining to testing of the application. Its contents include:

Testing scope - what is included and what is not included in the testing of the current project 

Assumptions - what are the assumptions that are made for this project 

Milestones - major dates like when testing is going to begin, when it is planned to end, what is the trace review date, what is the production date etc. 

Resources - the resources working on this project along with their contact details 

Defect tracking mechanism - what defect tracking tool will be used, what is the SLA for fixing Critical to Low level IRs etc. 

Test management procedures - who will be notified when there is a critical IR, what reports will be sent daily, if status calls will be held daily or weekly, where will it be held, who is required to join etc. 

Work allocation - resource distribution if more projects are being tested 

Entry and exit criterion - when can a project be accepted for testing (eg. only when smoke testing passes) and when can a project be termed as testing complete (eg. when all testcases are executed and all high level bugs are fixed)

The Quality Factor is also defined, as Q. So it is a number, which reflects the lossness of a circuit. higher the Q, the lower are the losses.

the quality factor is measurement of efficiency (or effectiveness) of a device or circuitry. In literal sense quality factor means qualitative performance of a device.

Testing is a process used for revealing defects in s/w and for establishing that the s/w has attained a specific degree of quality.

The s/w testing group’s main objective is to ensure that the s/w is doing what it is supposed to do as well as the s/w is not doing what it is not supposed to do. With this objective, it is clear that it is necessary to have a separate group for testing the s/w other than the group which developed it.

Also, bugs in the s/w can cause severe monetary as well as other loss to the organization. So it is important to allocate some budget for the testing group.
