Technical Questions

Cloud computing :: 

Cloud computing is an information technology (IT) paradigm that enables ubiquitous access to shared pools of configurable system resources and higher-level services that can be rapidly provisioned with minimal management effort, often over the Internet.

Server virtualization :

Server virtualization is a virtualization technique that involves partitioning a physical server into a number of small, virtual servers with the help of virtualization software. In server virtualization, each virtual server runs multiple operating system instances at the same time.

Server virtualization is more for a good reason. It offers the potential to dramatically save space and improve server efficiency. Vendors are in fierce competition to offer the most advanced tools that they hope will earn them the virtualization crown.

Hence, the given statement that 'Cloud computing uses Server virtualization.' is TRUE.

In Computers ::

A network is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another to allow the sharing of data.

An excellent example of a network is the Internet, which connects millions of people all over the world. Below is an example image of a home network with multiple computers and other network devices all connected to each other and the Internet.

Ex:: LAN, WAN, MAN, WLAN,...

In Business view::

Networking is defined as the act of making contact and exchanging information with other people, groups and institutions to develop mutually beneficial relationships.

VOIP is an acronym for Voice Over Internet Protocol, or in more common terms phone service over the Internet.

Voice over Internet Protocol is a category of hardware and software that enables people to use the Internet as the transmission medium for telephone calls by sending voice data in packets using IP rather than by traditional circuit transmissions of the PSTN.

Here in the given options, Skype is the only voice service that enables us to talk over internet.

Statement coverage is a white box test design technique which involves execution of all the executable statements in the source code at least once. It is used to calculate and measure the number of statements in the source code which can be executed given the requirements.

Code review is a software quality assurance activity in which one or several humans check a program mainly by viewing and reading parts of its source code, and they do so after implementation or as an interruption of implementation.

Impact Analysis is used in software testing to define all the risks associated with any kind of changes in a product being tested.

Impact Analysis is nothing but analyzing the impact of changes in the deployed product or application. It gives the information about the areas of the system that may be affected due to the change in the particular section or features of the application.

Why Impact Analysis is done :

1. It is done to understand the possible outcome of implementing the change. Inducing too much functionality into a product can reduce the overall performance of the product.

2. To identify all the files, documents and models that might have to be modified if team decides to implement the change in product

3. To estimate the effort needed behind implementing the change

4. To identify the task required to implement the change

5. It will list the dependencies on a specific element

The impact is analyzed on Requirements, Design & Architecture, impact on Test and impact on schedule.

A bootstrap is the process of starting up a computer. It also refers to the program that initializes the operating system (OS) during start-up.

It referred to a bootstrap load button that was used to initiate a hardwired bootstrap program, or smaller program that executed a larger program such as the OS.
