Answer

Abstraction enables GPS system to facilitate the utilization of well defined interfaces while offering room to add additional levels of functionality which are complex to handle.

Explanation

GPS system applies abstraction to be able to arrange level of complexity on which a user will interact with the system. For example, it establishes a link of satellite positioned and timed systems to allow a radio receiver obtain a signal in four dimension after synchronizing the data of latitude, longitude, attitude and time.

Answer:

Abstraction is used in GPS system <u><em>to provide better interfaces while adding the extra functionalities that are complex to manage</em></u>.

Further Explanation:

Global Positioning System (GPS): GPS is a satellite positioning system that uses satellites to provide <em>location, time synchronization</em> and <em>velocity</em> for air, <em>land </em>and <em>sea</em>.

The five main uses of GPS are:

  1. Location: Finding a position
  2. Navigation: When travelling from one position to other
  3. Mapping: For creating maps of different locations of universe
  4. Tracking: For monitoring the movement
  5. Timing: To find the time measurement

The applications of GPS are include:

  • Entertainment
  • Health and Fitness
  • Construction
  • Transportation
  • Emergency Response

In GPS, abstraction is used to reduce the design complexity of the computer system.

____ twisted pair is the least quality twisted pair wire that should be used in a data/voice application.
xxMikexx [17]

Answer:

Category 5 (Cat 5) twisted pair is the least quality twisted pair wire that should be used.

Explanation:

The reason is as follows:

  1. Category 1 twisted pair is not suitable for transmitting data but comes in handy for telephone communications. Hence, it should not be used in a data/voice application.
  2. Category 2 twisted pair is suitable for data transmission, however, it can only transmit at 4Mbps which is very slow. Hence, it should not be used in a data/voice application.
  3. Category 3 twisted pair can transmit data with speed reaching 10Mbps which is slow for voice/data communication.
  4. Category 4 twisted pair can transmit data with speed reaching 16Mbps and is used in token ring networks. It is slow for communicating in a voice/data application.
  5. Category 5 twisted pair is the least qualified to be used in a voice/data application because it can transmit data at speeds that reach 100Mbps.

Hence, Cat 5 or Category 5 twisted pair is the least quality twisted pair that should be used in a data/voice application.

Referential integrity constraints are concerned with checking INSERT and UPDATE operations that affect the parent child relation
Jet001 [13]

Answer:

a) true

Explanation:

In Computer programming, integrity constraints can be defined as a set of standard rules that ensures quality information and database are maintained.

Basically, there are four (4) types of integrity constraints and these are;

1. Key constraints.

2. Domain constraints.

3. Entity integrity constraints.

4. Referential integrity constraints.

Referential integrity is a property of data which states that each foreign key value must match a primary key value in another relation or the foreign key value must be null.

For instance, when a foreign key in Table A points to the primary key of Table B, according to the referential integrity constraints, all the value of the foreign key in Table A must be null or match the primary key in Table B.

Hence, the referential Integrity constraints ensures that the relationship between the data in a table is consistent and valid.

Hence, referential integrity constraints are concerned with checking INSERT and UPDATE operations that affect the parent child relationships.

<em>This ultimately implies that, referential Integrity are rules used in database management systems (DBMS) to ensure relationships between tables when records are changed is VALID (INSERT and UPDATE).</em>

<em>In a nutshell, it always ensures a primary key must have a matching foreign key or it becomes null. </em>

Users need to be able to make use of _____ , such as rumors, unconfirmed reports, and stories, when solving problems.
jekas [21]

Answer:

Informal information

Explanation:

The informal information system is employee based system design to meet personnel and vocational needs and to help in the solution of work-related problems. it also funnels information upward through indirect channels.

However, one of the most important reasons for why informal communication is critical to businesses is that it allows employees to give feedback to their superiors.

Thus, the informal or grapevine communication promotes social relationship among the participants. It helps to build up unity, integrity and solidarity among them and boosts up their morale. Grapevine or informal communication is faster than the formal communication.
