There are two types of locks:

1. Binary lock- A binary lock has two values or states: locked and unlocked like or 1 and 0, for simplicity). A different lock is allied with each database item X.

2. Shared and exclusive locks- The binary locking scheme is defined above is too restrictive in general due to the most one transaction can take hold on a given item. Several transactions must be allowed to access the same item X if they all access X for reading purposes only. But, if a transaction is to transcribe an item X, it should have exclusive access to X.

You can learn programming languages which are mostly used in Bioinformatics either in IT field. After that you have a chance to got both field opportunity.

Degree is helpful for your Job and knowledge because in diploma courses you have a limited period to learn but in degree have a sufficient time. Most companies hires candidates through degree courses.

The sequences that remain negligibly affected during evolution nd are least affected along the different line of orgnisms for example the tata box region common among all the eukaryotic and prokaryotic cells is uneffected and has remained non mutatedfrom time being.

In computer programming, event-driven programming is aprogramming paradigm in which the flow of the program is determined by events such as user actions (mouse clicks, key presses), sensor outputs, or messages from other programs/threads.

Conformation is an arrangement of atoms by free rotation with single bond. Configuration is an arrangement of parts or elements in a particular form, figure or combination.

Program is divided into parts is known as objects. Oops provides security using data hiding. Data cannot move easily from function to function, it can be kept public or private so we can control the access of data. Oops has access specifier a named public, private and protected etc. Example of oops language: c++, Java, VB.NET, C#.NET. It is used for code reusability, simplicity.
