Is the database simple or the network technology simple? Please, great gods
The computer science level three exam included two parts: database system and computer network technology. For database systems, the knowledge points were relatively scattered. It was relatively more complicated to master the knowledge of the SQL language, the principle of the relationship database, and the design of the database. On the other hand, computer network technology mainly involved network protocol, network topography, network security, and other aspects of knowledge. Relatively speaking, the knowledge points were more concentrated and less difficult. Therefore, in terms of learning difficulty, computer network technology might be easier. However, both database systems and computer network technology required sufficient practice and practice to master the relevant knowledge and skills. Therefore, no matter which part was chosen as the test content, one needed to study and prepare carefully.

Simple and clean
The word "wrap up" originally referred to the process of making bamboo slips in ancient times. In the pre-Qin era, people used bamboo slips to record information. However, the surface of the bamboo slips had a layer of bamboo green that was watery and oily. It was not easy to engrave words on them and was easy to be eaten by insects. In order to solve this problem, the ancients put the bamboo slips on the fire to make them dry, easy to engrave, and prevent insects from eating them. This process of roasting bamboo slips was called "wrapping up". Later, this term was also used to describe the completion of the filming of the film and television works.
