Answer:
Physical layer
Explanation:
OSI model stands for Open Systems Interconnection. The seven layers of OSI model architecture starts from the Hardware Layers (Layers in Hardware Systems) to Software Layers (Layers in Software Systems) and includes the following;
1. Physical Layer
2. Data link Layer
3. Network Layer
4. Transport Layer
5. Session Layer
6. Presentation Layer
7. Application Layer
Each layer has its unique functionality which is responsible for the proper functioning of the communication services.
In the OSI model, the physical layer is the first and lowest layer. Just like its name physical, it addresses and provides information about the physical characteristics such as type of connector, cable type, length of cable, etc., of a network.
This ultimately implies that, the physical layer of the network (OSI) model layer provides information about the physical dimensions of a network connector such as a RJ45. A RJ45 is used for connecting a CAT-5 or CAT-6 cable to a networking device.
The best I can say is to try it again until it works. Either that or you could somehow contact the company that made that app and explain what's been going on.
Answer:
Option A, Option B, and Option C are correct.
Explanation:
The foregoing provide instructions for the design of flowcharts indicating the ultimate state for all records, describing their operational operations, information, data flows as well as processing methods to also be recorded and then displaying information inserted or extracted from such a database as going via a processing activity (computer program).
So, the following are the reason that describes the other options are incorrect according to the scenario.
Answer:
The bird's-eye view that satellites have allows them to see large areas of Earth at one time. This ability means satellites can collect more data, more quickly, than instruments on the ground.
