Answer:
D. Routing and Switching
Explanation:
The purpose of a network is to connect computers and peripherals using switches and routers. These two let the devices connected to your network communicate with each other as well as talk to other networks.
Routers are used to tie multiple networks together. For example, you would use a router to connect your networked computers to the Internet and thereby share an Internet connection among many users. The router will act as a dispatcher, choosing the best route for your information to travel so that you receive it quickly.
Switches are used to connect multiple devices on the same network within a building or campus. For example, a switch can connect your computers, printers and servers, creating a network of shared resources. The switch would serve as a controller, allowing the various devices to share information and talk to each other. Through information sharing and resource allocation, switches save you money and increase productivity.

A general-use dimmer switch is required to be counted as ? where installed in a single-gang box on a circuit wired with 12 awg copper conductors.
Answer:
2 conductors.
Explanation:
A dimmer switch is an electrical switching or control device used to control the power or voltage to a compatible dimmer bulb.
It reduces the ambience if light bulbs by uniformly increasing the resistance of the switch when the knob is rotated to a lesser point. It is a circuit breaker as two conductors are connected to its terminals and a variable voltage resistor determines the flow of current between them.
Final answer:
A general-use dimmer switch is counted as a single device in a single-gang box wired with 12 AWG copper conductors, acting by increasing total resistance in the circuit.
Explanation:
A general-use dimmer switch should be counted as a single device when installed in a single-gang box on a circuit wired with 12 AWG copper conductors. The dimmer switch alters the flow of electric current to the lighting fixture, which in turn adjusts the intensity of the light the fixture produces.
When incorporating a dimmer switch, it's important to consider the total resistance in the circuit, as adding a dimmer generally increases the resistance and thus affects the circuit's overall performance.

Which is true about POP3 and IMAP for incoming email?
Both keep email on an email server by default
IMAP keeps email on an email server by default
Neither keep email on an email server by default
POP3 keeps email on an email server by default.
Answer:
IMAP keeps email on an email server by default
Explanation:
IMAP and POP3 both are email receiving protocols. These protocols used to access the emails from the email server to client inbox.
In POP3 (Post Office Protocol 3) emails are received in the user inbox. This protocol removes the emails from email servers and keep in user inbox.
While in IMAP (Internet Message Access Protocol) the message is directly access form the email server, it will not stored on the local user device.
So, the IMAP is the only protocol in which email are kept saved on email serve by default.

Answer:
"Algorithm" is the correct answer to this question.
Explanation:
An algorithm is an incredibly Well-definable way, that fixes the computer problem. In the computer, if there are multiple types of problems so, it will use a single algorithm to solve it. It is known as an optimization method, which is the most effective way over a certain function.
In the programming language, every function is called the algorithm, that executes any task in steps. It is also used as a mathematical method for several applications in computer science.Final answer:
The central concept in computer science as proposed by Norman Gibbs and Allen Tucker is the algorithm, reflecting the importance of problem-solving strategies set by instructions, exemplified by Alan Turing's contributions to the field.
Explanation:
According to the definition of computer science proposed by Norman Gibbs and Allen Tucker, the central concept in computer science is the algorithm. An algorithm is a problem-solving strategy characterized by a specific set of instructions. This is reflective of the legacy of Alan Turing's seminal work, wherein the Universal Turing Machine could perform computations based on a given algorithm. Turing is considered the father of theoretical computer science and artificial intelligence, with the concept of the modern computer deriving from his theories.
Thinking, as a form of computation, parallels the way a computer processes data through software to produce outputs. The IEEE Computer Society's vision reinforces the centrality of advancing the theory and practice of algorithms and computation. Together, these components come to define the pursuit of computer science as a discipline deeply rooted in complex problem-solving and the creation of solutions.

Answer: Hard drive
Explanation:
Lin is booting up his computer, and during the boot process, the computer powers down. After several unsuccessful attempts to boot his computer, he decides that he needs to start the troubleshooting process. Lin thinks that the problem could be in the power supply, so he uses a power supply tester. The test shows that the power supply is functioning properly.
What should Lin check next in the troubleshooting process?
a.
Processor
b.
Motherboard
c.
RAM
d.
Hard drive
Answer:
A. Processor.
Explanation:
When a computer system works working or does not boot, it is mostly ask a result of power supply failure.
The system does not come on, that is, the fan and screen does not come up and the caps lock indicator is not blinking. The power supply shows that the power is good.
When the processor is not sitting properly and when the motherboard has failed, the signs mentioned above are observed.
Not to escalate the problem, test for the processor status as a probable cause with another functional and compatible processor before the motherboard.
Final answer:
After testing the power supply, the next step is to inspect the motherboard and then possibly the processor, as they are critical to the computer's boot process, and issues with them can lead to power-down scenarios during boot.
Explanation:
Since Lin has already tested the power supply and confirmed it is functional, the next step in the troubleshooting process would be to check the components most essential for the computer's boot process. An abrupt power down during boot can be caused by a variety of hardware issues. The logical step following the power supply would typically be to check the motherboard as it is a central hub connecting all other components. Issues with the motherboard can prevent the computer from completing the boot process. If the motherboard has diagnostic LEDs or beep codes, Lin should check those to identify any potential issues. It's also possible that the processor (CPU) is overheating or failing, which could cause the system to shut down to prevent damage. However, problems with the RAM or hard drive usually don't lead to abrupt power loss; they generally result in error messages or system instability rather than power issues.

A computer record is used to store all the information about one transaction, but several such records must be used to store the information about one employee, one inventory part, and so forth, on a master filea.trueb.false
Answer:
True
Explanation:
A single file can be used to record/ store all the information regarding a transaction because in a transaction there are less complexities. a simple transaction involves an exchange/communication between a buyer and a seller which involves exchange in finances between the buyer and the seller.
An employee can be involved in several activities like work activities and multiple transactions while a single inventory part record is different from an employee's record and any other form of transaction. hence separate files have to be created for each of these activities.
To have an easy access to this information when needed a master file is created to store all the individual files.
