The implementation stage of the SDLC is when the system is moved into operation where it can be used. What stage PRECEDES the implementation stage and what happens in this preceding stage
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.

Based on the information that is given, a steep reduction in the memory that's available is known as a memory leak.
A memory leak simply means a form of resource leak which occurs when a computer program manages memory allocations incorrectly in such a way that the memory that isn't needed anymore aren't released.
It should be noted that a memory leak is also a steady reduction in memory available on the heap to the point where it's exhausted. It can also be when an object that is stored in memory can't be accessed by the running code.

A ______ error occurs when the program's grammar and punctuation is correct, but something happens to halt the program before it is finished.
1. Runtime
2. Syntax
3. Logical
Answer:
Logical error
Explanation:
Answer:
Runtime
Explanation:
The program stops execution before the end of the instructions has been reached. It is not due to poor grammar/punctuation which would be a syntax error. A logical error would be due to an error in the programmer's logic but would not cause the program to terminate abnormally. This is also not the case.

A NAND gate is a type of logic gate that produces an output of false only when both of its two inputs are true. Otherwise, the gate produces an output of true. Which of the following Boolean expressions correctly models a NAND gate with inputs P and Q?
a. (NOT P) AND (NOT Q).
b. (NOT P) AND Q.c. NOT (P AND Q).d. NOT (P OR Q).
A NAND gate combines the NOT gate and the AND gate.
For inputs P and Q, the boolean expression for the NAND gate is c. NOT (P AND Q)
The NAND gate means:
NOT AND
Assume the inputs are x and y, then the formula would be:
NOT (x AND y)
In this case, the input variables are P and Q.
So, we replace x and y with P and Q, respectively.
The formula becomes NOT (P AND Q)
Hence, the correct expression is (c)

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;
Physical LayerData link LayerNetwork LayerTransport LayerSession LayerPresentation LayerApplication LayerThe transport layer accept data packets from session layer, breaks them into smaller units and then transmits (sends) them to the network layer, without any duplication of data.
In this scenario, a function provided by the transport layer of the open systems interconnection (OSI) model is transportation (transmission) of the correct web page (data) to the correct browser window (software application), especially through the use of source and destination port numbers assigned to the software application.

(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.

In Java, a reference variable is ________ because it can reference objects of types different from its own, as long as those types are related to its type through inheritance.
Answer:
polymorphic
Explanation:
An example of polymorphic reference, suppose you have 3 classes: Main, Product and SpecificProduct. If SpecificProduct extends Product this means it is a product class but with something else to complement.
Say you want to reference an object of product in the main class, you can do it the classic way:
Product pd = new Product();
Or you can do it polymorphic, like this:
Product pd = new SpecificProduct();
The program will accept just fine because SpecificProduct is extending Product. When you do it like this, we say the reference you made was a polymorphic reference
