Technology Questions

The main attributes are discussed below:

Maintainability: For each new release need to update the test automation suites.

Reliability: Accuracy and repeatability of the test automation.

Flexibility: Ease of working with all the different kinds of automation test ware. 

Efficiency: Total cost related to the effort needed for the automation.

Portability: Ability of the automated test to run on different environments.

Robustness: Effectiveness of automation on an unstable or rapidly changing system. 

Usability: Extent to which automation can be used by different types of user.

A foreign key is a reference to another table. It is used to establish relationships between tables. For example, relationship between employee and professor table. One employee can have multiple professors. The Primary key of employee becomes foreign key of professor.
Example:
create table employee ( id number NOT NULL, professor_id NOT NULL, Name varchar(200) Constraint prim_id Foreign key(id) references professor(professor_id) );

bcoz interface does not contains any initializers and constructors to initialize its data members.

TTL is a value in data packet of Internet Protocol. It communicates to the network router whether or not the packet should be in the network for too long or discarded. Usually, data packets might not be transmitted to their intended destination within a stipulated period of time. The TTL value is set by a system default value which is an 8-bit binary digit field in the header of the packet. The purpose of TTL is, it would specify certain time limit in seconds, for transmitting the packet header. When the time is exhausted, the packet would be discarded. Each router receives the subtracts count, when the packet is discarded, and when it becomes zero, the router detects the discarded packets and sends a message, Internet Control Message Protocol message back to the originating host.

 .htaccess is a configuration file running on Apache server.These .htaccess file used to change the functionality and features of apache web  server .

 e.g   .htaccess file used for url rewrite .

An Interactive report allows the user to participate in retrieving and present data at each level.while classical report doesn't have access to interact.

Unwrapping is also called as unpacking or unboxing.

Getting the private data stored in the object by using methods is called unpacking or unwrapping.

1 : InnoDB provides us row level locking while MyISAM provides us table level locking.

2 : InnoDB offers foreign key constraints wheres in MyISAM does not have foreign key constraints.

3 : InnoDB does not have full text search wheres MyISAM provides us full text search.
