Answer:
computer is an electronic machine which work on the basic principle" ipo"(input process and output.
it's characteristics are
Accuracy
Computers perform calculations with 100% accuracy. Errors may occur due to data inconsistency or inaccuracy.
Diligence
A computer can perform millions of tasks or calculations with the same consistency and accuracy. It doesn’t feel any fatigue or lack of concentration. Its memory also makes it superior to that of human beings.
Versatility
Versatility refers to the capability of a computer to perform different kinds of works with same accuracy and efficiency.
Reliability
A computer is reliable as it gives consistent result for similar set of data i.e., if we give same set of input any number of times, we will get the same result.
Answer:
Option D is correct.
Explanation:
A high-level safety violation could be anticipated to have a serious or disastrous negative impact on organisational activities, organisational assets.

Answer:
Network.
Explanation:
The Transmission Control Protocol/Internet Protocol (TCP/IP) model is a standard networking protocol which allows network devices such as routers, switches, and host computers to interconnect and communicate with one another over a network. The Transmission Control Protocol/Internet Protocol (TCP/IP) model comprises of four (4) layers and these includes;
I. Application layer.
II. Transport layer.
III. Internet layer.
IV. Network layer.
The network layer in the Transmission Control Protocol/Internet Protocol (TCP/IP) model is responsible for delivering data between two nodes.
Basically, this layer known as network layer is the fourth layer of the Transmission Control Protocol/Internet Protocol (TCP/IP) model and it is typically responsible for the transmission of packets from one network device to another.
