IT is the process of storing data, retrieving, processing and even manipulating the data by the use of a computer or any other electronic means. The stored data is in the form of electronic images of even numbers and pictures.It services is the process of ensuring that these process are working efficiently and we shall see this in some short while.
Big institutions normally have the in-house IT experts to help in the handling of these kind of data. For one to be an IT expert, he or she needs to a minimum of a bachelor degree from a recognized institution of higher learning. The article will only be confined to the Jobs that IT personnel normally do.
There is the need to store data. The data is normally stored in given formats, such that the retrieval requires special permissions or even the pattern can only be understood by them that are involved in the designing and storage process. The data is mainly stored by in the databases and as such, specialized person is needed to design the required database. The designing process is not a walk in the park due to the required expertise and also the need the logistics.
We will focus on the retrieving concept of the already stored database. The stored data is normally in form of numerals and even some are in pictures. Care and already established procedures need to be followed in ensuring that the retrieval process is fine and that it does not hurt other data and items already stored in the database. To fine tune the retrieval process, the data is normally stored in packets and each packet has got its own unique identifier such that, the it can be called or even retrieved using the said identifier. Thus, when retrieving the said data, you only need to have the key, call the packet and you have the data in your hands.
Manipulation is the other issue in ensuring that the data is fine. There are endless ways of doing data manipulations. For example, it can be manipulated by the use of the data analysis or it can even be by the form of transcribing and coding. When meaning is found and the data stored in another format, we say that the data is being manipulated.Manipulation is mostly done in the last stages where the data is being used. Manipulation is normally done in an attempt to get the meaning of words, phrases and audio files.
There is also data transmission. Data can be transmitted through the internet medium or even through other means like the use of wires. Transmitting improves the idea of sharing data and information. Through transmission, security is guaranteed through encapsulation and also providing other security features.
