Answer:
columns, rows
Explanation:
In Computer programming, a atabase schema refers to the logical design of the database while the database instance refers to a snapshot of the data found in a database at a given instant in time.
Basically, in database management, the term "schema" is used to denote a representation of data while the term "instance" is used to denote an instance of time.
A database schema is a structure which is typically used to represent the logical design of the database and as such represents how data are stored or organized and the relationships existing in a database management system. There are two (2) main categories of a database schema; physical database schema and logical database schema.
Also, a database instance is a snapshot of the data in the database at a given instant in time and as such represents an operational database by following the conditions, validation and constraints set for a database management system.
These data can be stored or organized in a database management system through the use of multiple-column record formats.
In a multiple-column record of a data file, columns represent different variables and rows represent different cases (respondents) such as experimental data, independent observations etc.
Answer:
1)PERFORMANCE
2)RANGE
Explanation:
A mesh network can be regarded as local network topology whereby infrastructure nodes connect dynamically and directly, with other different nodes ,cooperate with one another so that data can be efficiently route from/to clients. It could be a Wireless mesh network or wired one.
Wireless mesh network, utilize
only one node which is physically wired to a network connection such as DSL internet modem. Then the one wired node will now be responsible for sharing of its internet connection in wireless firm with all other nodes arround the vicinity. Then the nodes will now share the connection in wireless firm to nodes which are closest to them, and with this wireless connection wide range of area can be convered which is one advantage of wireless mesh network, other one is performance, wireless has greater performance than wired one.
Some of the benefits derived from configuring a wireless mesh network is
1)PERFORMANCE
2)RANGE
Answer:
"Cyberspace
" is the right answer.
Explanation:
- Cyberspace seems to be an interactive computational environment, unconstrained by distance and perhaps other functional disabilities. William Gibson developed the word for representing a sophisticated augmented reality infrastructure in his story Neuromancer.
- The virtual space generated over the network through synchronized computing devices.
So that the above would be the correct answer.
The answer most likely B NOT SURE )
