The three effects on the overall system performance that might result are:
- No Space - this is when the Ram memory can be full due to different reasons.
- The speed of the hard disk.
- Hard disk space.
<h3>What is Memory Deallocation?</h3>
Operating system is known to be one that tends to share or allocates memory for the jobs that need to be processed.
Once the processing is said to be completed and no other jobs is known to be waiting for the memory space, this is the time that one can be able to use to release the said memory.
Note that the Releasing the allocated memory space is said to be deallocation.
Hence, The three effects on the overall system performance that might result are:
- No Space - this is when the Ram memory can be full due to different reasons.
- The speed of the hard disk.
- Hard disk space.

Answer:
Programming & Software Development
Explanation:
Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.
Some of the models used in the software development life cycle (SDLC) are;
I. A waterfall model.
II. An incremental model.
III. A spiral model.
Also, programming refers to a software development process which typically involves writing the sets of instructions (codes) that are responsible for the proper functioning of a software.
In this scenario, Brian is a computer engineer who writes security software for a banking system.
Thus, the pathway in the Information Technology career cluster that Brian's job falls into is Programming & Software Development.
1. Based on Scenario A, the packets should be encapsulated in multiple frames to minimize the re-transmission overhead.
This is because there will be the need to re-transmit the packets because the network environment is not reliable and accurate. Therefore, a single frame may be too costly when the need for re-transmission arises.
2. Based on Scenario B, the packets should be encapsulated in a single frame because of the high level of network reliability and accuracy.
There will not be further need to re-transmit the packets in a highly reliable and accurate network environment. This environment makes a single frame better.
Encapsulation involves the process of wrapping code and data together within a class so that data is protected and access to code is restricted.
With encapsulation, each layer:
- provides a service to the layer above it
- communicates with a corresponding receiving node
Thus, in a reliable and accurate network environment, single frames should be used to enhance transmission and minimize re-transmission overhead.
