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 said data is information that is in form of pictures, or even numbers.It services is the process of ensuring that these process are working efficiently and we shall see this in some short while.
IT services are mostly found in big institutions and mainly they involve data storage, protection, retrieving and even manipulation. IT personnel are always one of the most smartest people with at least a minimum qualification from recognized universities. The article will mainly focus on the kind of the things that these IT personnels normally are supposed to do.
To begin with, there is the need for data storage. Storing data means that, the data is in some patterns or even sequences such that it cannot be retrieved without the consent of the relevant person. The data is mainly stored by in the databases and as such, specialized person is needed to design the required database. 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 stored data is normally in form of numerals and even some are in pictures. This means a lot of care need to be taken in the retrieving process so that it does not affect the other data that is stored in the same 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 a lot and different ways of ensuring that the data is changed from its original form. 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. In all this, we say that the data is being 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.
There is the moving of data from one station or computer to the other. Data can be transmitted in various means like for example the use of internet or even by the use of cables in networking. Transmitting improves the idea of sharing data and information. There is security in the transmission process through coating of the data and provision of passwords.
