The storage, retrieval and manipulation of data by use of digital medium or electronic means is some of the answers that IT services seeks to answer. The stored data is in the form of electronic images of even numbers and pictures.We can hence say that, IT services is the process of ensuring that these processes are working normally or are working efficiently.
IT services are mostly found in big institutions and mainly they involve data storage, protection, retrieving and even manipulation. 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.
Storage of data is always an aspect in this. 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 not stored in the normal computer programs, but special people need to come on board to help in the designing process. The process of designing is a complex one since it requires full concentration and off course expertise.
Retrieving the already stored data in the database. The data is normally stored in terms of texts and figures. 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. When one wants to retrieve the data, he only types or calls the key relating to the given data packet.
Manipulation is the other issue in ensuring that the data is fine. There are endless ways of doing data manipulations. Data manipulation can involve getting the meaning of the words or even in getting the meanings of certain words through such things as data analysis or even transcribing the audio voices. When the above has been done, the data is said to have been manipulated.Manipulation is always the last stage in the whole process. Changing the form of the data is always done to get the meaning behind the pictures or even words.
The last point involves transporting of data. There are many ways of transmitting the data like the use of digital medium or even the use of other means like for example use of connecting cables. This is important since it ensures sharing of data between more than one computers, organizations and even countries. There is security in the transmission process through coating of the data and provision of passwords.
