<u>The first tools that analyzed and extracted data from floppy disks and hard disks were MS-DOS tools for </u><u>IBM</u><u> PC file systems</u>. A file system is a structured representation of data and a set of metadata describing this data. The file system of the IBM supports stream input/output and storage management, providing a structure over all information stored in the system.

All of the following changes have created an urgent need for centralization except The number of qualified software programmers and PC repair technicians is dwindling
<h3><u>
Explanation:</u></h3>
When the processing tasks are carried out on a centralized server it refers to the Centralization. In this type of architecture all the computer systems will be connected to a single server in which all the computational work are performed. The client machines that are connected to the central server will get the resources for computing from the centralized server.
The main reasons for the purpose of centralization includes the following such as the development in the internet that required many computer networks, the basic functioning of the business in which the needed applications are fed on the intranets, the cost associated in the maintenance of personal computers on the single network.
