Technology Questions

“In software testing, a test harness or automated test framework is a collection of software and test data configured to test a program unit by running it under varying conditions and monitor its behavior and outputs. It has two main parts: the test execution engine and the test script repository.”

bcoz the static method does not contains the 'this' reference.

The Asynchronous Transfer Mode or ATM is a connection technology that works by transmitting data into organized 53 bytes (small) packages through a physical environment with a high efficiency. Packing data into small cells reduces transportation delay so the speeds reached by this technology are very high; it can reach even 10 Gb per second.

It is a way to convert the original text of the stored procedure into encrypted form. The stored procedure gets obfuscated and the output of this is not visible to

Hub is device to connect two devices, switch is a network bridge which processes and routes data approirately over network layer of OSI Reference model

WDM is conceptually the same as FDM, except that the multiplexing and demultiplexing  involve light signals transmitted through fiber optics channel.

Star schema: A highly de-normalized technique. A star schema has one fact table and is associated with numerous dimensions table and depicts a star.

Snow flake schema: The normalized principles applied star schema is known as Snow flake schema. Every dimension table is associated with sub dimension table.

Differences:

- A dimension table will not have parent table in star schema, whereas snow flake schemas have one or more parent tables.

- The dimensional table itself consists of hierarchies of dimensions in star schema, where as hierarchies are split into different tables in snow flake schema. The drilling down data from top most hierarchies to the lowermost hierarchies can be done.

- Web browser functions are to provide the resources or information to the user when asked by them. 

- It processes the user inputs in the form of URL like https://www.google.com in the browser and allows the access to that page. 

- URL is used to identify the resources and fetch them from the server and displays it to the client. 

- It allows the user to interact with the web pages and dynamic content like surveys, forms, etc. 

- It also allows the user to navigate through the complete web page and see its source code in the HTML format. 

- It provides security to the data and the resources that are available on the web that is by using the secure methods.
