I think this is a best intro to Scrum

As its name implies, exploratory testing is about exploring, finding out about the software, what it does, what it doesn’t do, what works and what doesn’t work. The tester is constantly making decisions about what to test next and where to spend the (limited) time. This is an approach that is most useful when there are no or poor specifications and when time is severely limited. Exploratory testing is a hands-on approach in which testers are involved in minimum planning and maximum test execution. The planning involves the creation of a test charter, a short declaration of the scope of a short (1 to 2 hour) time-boxed test effort, the objectives and possible approaches to be used.

So in this case communication becomes so difficult and painful. To speak the language of testing, you need to learn its vocabulary. Find below a huge collection of testing vocabulary:

What is a RESTful API? REST (Representational State Transfer) is a simple stateless architecture that uses HTTP protocol. In a Client-Server Application most of the web services use REST API so that clients, third party applications can access its resources using URI (Uniform Resource Identifier) How do we do the Performance testing of RESTful API’s?

Testing SOAP/REST Web Services Using JMeter Representational State Transfer (REST) uses the HTTP request method with the most popular being: GET, POST, PUT and DELETE. The responses return status codes indicating success or failure, along with any applicable headers, and JSON representing the affected fields (or nothing) in the message-body. Read below and you can easily learn how to write a JMeter script with one of these methods!

Definition: End-to-end testing is a methodology used to test whether the flow of an application is performing as designed from start to finish. The purpose of carrying out end-to-end tests is to identify system dependencies and to ensure that the right information is passed between various system components and systems. For example, a simplified end-to-end testing of an email application might involve: 1. Logging in to the application 2. Accessing the inbox 3. Opening and closing the mailbox 4. Composing, forwarding or replying to email 5. Checking the sent items 6. Logging out of the application

A relational database is a collection of data items organized as a set of formally-described tables from which data can be accessed or reassembled in many different ways without having to reorganize the database tables.

User Acceptance Testing (UAT), also called beta testing, is one sure way to reduce or eliminate change requests, and drastically reduce project costs. UAT is an effective process with a high rate of return for those who take the time to implement and follow its discipline.

Post based on my past QA job in 3VR company. America and Canada using NTSC, which stands for National television system committee. This was the first colour tv broadcast system. NTSC is also used in Asia, including Japan. Western Europe and Australia using PAL, or phase alternating line format. PAL was developed in the early 1960's. The increased bandwidth allows for better picture quality. Eastern Europe and France use SECAM, or sequential couleur avec memoire (sequential color with memory). SECAM uses the same bandwidth as PAL but transmits the colour information sequentially.

I was involved in test implemented to app feature "Search" in one of my projects called "Address Book" (contacts). And I do understand how important correct search algorithms form is and today will slightly share my knowledge with you. Today the "Search" functionality part of many programs and web services. Some searches involve looking for an entry in a database, such as looking up your record in the IRS (Internal Revenue Service) database. Other search algorithms trawl through a virtual space, such as those hunting for the best chess moves. Although programmers can choose from numerous search types, they select the algorithm that best matches the size and structure of the database to provide a user-friendly experience.
