Answer:
Case-based reasoning.
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.
In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.
This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.
Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.
Case-based reasoning is a problem-solving technique where each problem in a database is stored with a description and keywords that identify it. It is typically based on cognitive science and artificial intelligence.
Answer:
Yes
Explanation:
Depending on the ethernet standard used, the IEEE 802.3 is faster than the WIFI (IEEE 802.11ac).
The ethernet protocol on cabled networks are of different speed based on ethernet standard which ranges from 10 Mega-bits to 100 Giga-bits per second. This protocol is found in the physical layer of the OSI model.
The wifi 802.11ac also known as wifi 5 is a wireless connection medium in the physical layer of the OSI model. It has a range of aggregate speed capacity of 433 mega-bits per second to 6.77 giga-bits per second.
