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.We can hence say that, IT services is the process of ensuring that these processes are working normally or are working efficiently.
Big institutions normally have the in-house IT experts to help in the handling of these kind of data. IT experts are always learned individuals with minim of bachelor degrees from recognized institutions. The article will only be confined to the Jobs that IT personnel normally do.
To begin with, there is the need for data storage. 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 requires high skills and also the logistics required are quite expensive.
The other aspect that IT services seeks to answer the retrieval of the already stored data. he data that stored is normally in terms of texts and figures. This means that, such data must be retrieved in a given manner that it does not affect other information that is stored in the same database. To ensure this is achieved, the data are always in packets and each packet has got a specific identifier called a key. When one wants to retrieve the data, he only types or calls the key relating to the given data packet.
Can decide to do data manipulation. There are a lot and different ways of ensuring that the data is changed from its original form. For instance, a person can do data analysis incase the data is in figures and numbers or even find the meaning of the words used in the audio voices if the the file is in terms of the sound. When the above has been done, the data is said to have been manipulated.Manipulation is mostly done in the last stages where the data is being used. 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. Through the data transmission, it is possible for one to get the information shared between different organization. There is security in the transmission process through coating of the data and provision of passwords.
