PART I. ENGLISH (5 points ):
Data networks developed as a result of business applications that were written for microcomputers. At that
time microcomputers were not connected as mainframe computer terminals were, so there was no efficient
way of sharing data among multiple microcomputers. It became apparent that sharing data through the use
of floppy disks was not an efficient or cost-effective manner in which to operate businesses. Sneakernet
created multiple copies of the data. Each time a file was modified it would have to be shared again with all
other people who needed that file. If two people modified the file and then tried to share it, one of the sets of
changes would be lost. Businesses needed a solution that would successfully address the following three
problems:
• How to avoid duplication of equipment and resources
• How to communicate efficiently
• How to set up and manage a network
Businesses realized that networking technology could increase productivity while saving money. Networks
were added and expanded almost as rapidly as new network technologies and products were introduced. In
the early 1980s networking saw a tremendous expansion, even though the early development of networking
was disorganized. In the mid-1980s, the network technologies that had emerged had been created with a
variety of different hardware and software implementations. Each company that created network hardware
and software used its own company standards. These individual standards were developed because of
competition with other companies. Consequently, many of the new network technologies were incompatible
with each other. It became increasingly difficult for networks that used different specifications to
communicate with each other. This often required the old network equipment to be removed to implement
the new equipment.
