◉ Hierarchical Database
Answer: Organizes data by using tree-like or organizational chart
type structure.
*Main data points can have multiple sub-data points (Parent/child
structure)-Subpoints can only have one main data point.
* Records can be broken up so one portion is in one location and
another is in another section.
Ex: Employee database could list all employees, but a child relation
could contain info about employee position, pay level,
responsibilities. Another child relation could include info about
employee projects. Sub data is always specific to main data point.
◉ Tuples
Answer: Records represented by rows.
◉ Unshielded Twisted Pair (UTP)
Answer: Most commonly used network connections. Looks just as it
sounds, wires twisted together in a pair.
, ◉ Fiber Optic Cable
Answer: Transmits via light pulses as opposed to electromagnetic
ones.
◉ Twisted Pair
Answer: Network connection commonly used in the past. It is still
seen a lot today because it was used extensively in the phone
systems. Is cheap and and already in place.
**transmits using electromagnetic waves.
◉ Coaxial Cable
Answer: Commonly used network connection.
*Transmits using electromagnetic waves.
◉ Bandwidth
Answer: Transfer rate permissible over the media, and is described
as bps or b/s (bits per second).
**Modern bandwidth is described in millions/billions bits per
second (i.e. Mbps or Gbps)
*Older tech limited to thousands, (i.e. 56 Kbps)
◉ Network Hub
Answer: Device that connects multiple computers together.
