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:
Issue the Dcdiag on all domain controller servers.
Explanation:
Active directory is a database that holds information of client's authentication for service access in a server. Domain controllers in servers holds these active directories, to replicate client's credentials for quick response to access to the server.
When a server domain can not contact the active directory domain controller, the Dcdiag command is issued on the server to check for connectivity issue to the DNS, AD replication, SYSVOL replication etc.
Answer:
Telecommunication is also known as telecom(s), is the exchange of information over significant distances by electronic means, referring to all types of voice, data, and video transmission. This is a broad term that includes a spacious telecommunication field called the electromagnetic wireless range of technologies and communications infrastructures, such as wired phones; mobile devices, such as cellphones; microwave communications; fiber optics; satellites; radio and television broadcasting; the internet; and telegraphs.
A complete, single telecommunications circuit consists of two stations, each equipped with a transmitter and a receiver. The transmitter and receiver at any station may be combined into a single device called a transceiver. The medium of signal transmission can be via electrical wire or cable -- also known as copper -- optical fiber, electromagnetic fields, or light. The free space transmission and reception of data by means of communications. information
