Information technology is an essential service required by all industries to manage their operations. In house IT service is very expensive. It is always better to have an outsourced IT service team to manage an organization which saves cost, manpower and time. Your outsourced partner will ensure how well your IT services will be managed. So choosing a right partner is very much important.
There are several services provided and maintained by IT service providers such as data backup facility, cloud computing, video conferencing, online security, setting up virtual office, server consolidation, handling connectivity, IT procurement and many more.
Data storage is one of the key aspects of IT. A data storage device is a device for storing data. Recording can be done using virtually any form of energy, spanning from manual muscle power in handwriting, to acoustic vibrations in phonographic recording, to electromagnetic energy modulating magnetic tape and optical discs.

A storage device may hold information, process information, or both. A device that only holds information is a recording medium. Devices that process information may either access a separate portable recording medium or a permanent component to store or retrieve data.
Electronic data storage system requires electrical power to store and retrieve that data. Most storage devices that do not require vision and a brain to read data fall into this category. Electromagnetic data may be stored in either an analog data or digital data format on a variety of media. This type of data is considered to be electronically encoded data, whether it is electronically stored in a semiconductor device, for it is certain that a semiconductor device was used to record it on its medium. Most electronically processed data storage media are considered permanent (non-volatile) storage, that is, the data will remain stored when power is removed from the device. In contrast, most electronically stored information within most types of semiconductor (computer chips) microcircuits are volatile memory, for it vanishes if power is removed.

A database management system is a software application that interacts with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is designed to permit the definition, creation, querying, update, and administration of databases. Well-known DBMSs include MySQL, PostgreSQ, Microsoft SQL Server, Oracle, Sybase and IBM DB2. A database is not generally portable across different DBMSs, but different DBMS can interoperate by using standards such as SQL and ODBC or JDBC to allow a single application to work with more than one DBMS.
