The stage that precedes the implementation stage of SDLC is testing and it involves checking the functionality of the system.
System design involves the process of determining an overall system architecture, which typically comprises the following:
Hardware.End users.Physical processing components.Software.Communication channel.Generally, there are seven (7) main stages in the systems development life cycle (SDLC) model and these include:
1. Planning.
2. Analysis.
3. Design.
4. Development.
5. Testing.
6. Implementation.
7. Maintenance.
From the above, we can deduce that the stage which precedes the implementation stage of SDLC is testing.
During the testing stage of SDLC, a quality assurance (QA) expert checks the system to determine whether or not it is functioning properly before it is deployed for operation, which is where the system can be used.

which scenario describes a function provided by the transport layer?
The scenario that best describes a function provided by the transport layer of the open systems interconnection (OSI) model is: C. A student has two web browser windows open in order to access two web sites. The transport layer ensures the correct web page is delivered to the correct browser window.
OSI model is an acronym for open systems interconnection and it comprises seven (7) main layers, which typically starts from the hardware layers (layers in hardware systems) to the software layers (layers in software systems) and they include the following in sequential order;

(b) When a computer systems RAM becomes full it can use virtual memory.
Explain what happens if the computer does not have any virtual memory.
Answer:
it won't be able to run
Explanation:
because computer runs on physical memory
If a computer does not have any virtual memory, the consequences of running out of physical RAM can be quite problematic.
When the RAM becomes full, the operating system relies on virtual memory as a way to supplement the physical memory shortage. Without virtual memory, the system would have no way to manage or accommodate the excess data that needs to be stored temporarily.
As a result, the computer would likely start experiencing severe slowdowns, freezing, or crashing when attempting to run applications that require more memory than is available.
In extreme cases, the system might even become unresponsive or display error messages indicating a lack of memory. Virtual memory acts as a safety net, allowing the computer to continue functioning by utilizing a portion of the hard drive as temporary memory storage when physical RAM is exhausted.
Without this essential feature, the computer's ability to multitask and handle memory-intensive tasks would be severely hindered.
