When you modify or delete data present in a database, you are ________?
What port does rdp use by default and from what range of numbers should you select a private port number?
By default, RDP (Remote Desktop Protocol) uses port 3389. For selecting private port numbers, you should use the range from 49152 to 65535.
Remote Desktop Protocol (RDP) is a network protocol used to remotely connect to another computer. By default, RDP uses port 3389. This port number acts like an apartment number in a building, making sure that traffic is directed to the correct application on a server.
When selecting a private port number, it's crucial to choose from the range of 49152 to 65535, which is known as the dynamic or private port range. These port numbers are not assigned to any specific services and are available for any application to use.
Ports play a significant role in how applications communicate over networks, with different ports designated for different services like HTTP (port 80) and FTP (port 21), although these can sometimes be customized by administrators as needed.

You live "out in the middle of nowhere" and feel there is no need to protect your internet connection because there is no one that lives near you. one day you are unable to connect to the internet. after calling tech support you find that someone has hacked into your router and has changed all the settings. fortunately the hacker only wanted to use your internet connection and did not view any information on your computer. your decision to leave your router unprotected risked the integrity of the information on your computer. select yes or no.
Users reside "inside the middle of nowhere" and think that and no need to secure their connection to the internet so nobody lives next door, and the further discussion can be defined as follows:
In this, the user can't access the internet one day, upon calling technical assistance, we discover that someone has hacks through the router and altered all of its settings. Fortunately, the hacker was only interested in your internet access and did not look at any of your computer's data. So, the choice to leave your connection unencrypted exposed yourself to hazards to authenticity on your computer's data.Therefore, the given statement is "False".

What is the ratio between total bits required for such a cache implementation over the data storage bits?
What is a series of instruction or commands that a computer follows; used to create software
A program is an established set of instructions that a computer tracks to perform a task. The program is put into a storage area manageable to the computer and memory can also comprise the information that the instruction operates on. The computer program changes to one instruction and accomplishes it and then gets the following instruction. Programs can be considered as interactive or batch in relations of what drives them and how constantly they run. An interactive program obtains data from an interactive user or perhaps from another program that put on an interactive user. A batch program tracks and does it work and then stops and can be in progress by interactive users who appeal their interactive program to run the batch program.

The ampacity of a No. 12 aluminum wire with RHW insulation installed in a raceway that has 19 other wires is
A. 7 A.
B. 5 A.
C. 10 A.
D. 15 A.
The ampacity of a No. 12 aluminum wire with RHW insulation installed in a raceway with 19 other wires is most accurately 7 A, as the NEC dictates derating to 50% for more than 9 conductors, which is 7.5 A. We typically select the nearest standard size of overcurrent protection device below this value, giving us 7 A in this case.
Explanation:The student is asking about the ampacity of a No. 12 aluminum wire with RHW insulation when installed in a raceway with 19 other wires. The term ampacity refers to the maximum current an electrical conductor can handle before deteriorating under the heat caused by electrical resistance, which is an important consideration in electrical wiring installations. According to the National Electrical Code (NEC), the base ampacity of No. 12 aluminum wire is generally 15 amps. However, when multiple wires are bundled together, as in a raceway, the ampacity must be derated due to the reduced ability to dissipate heat.
For 4-6 current-carrying conductors, the NEC suggests derating to 80%, 7-9 to 70%, and more than 9 to 50%. Therefore, with 20 conductors, the ampacity would be derated to 50% of 15 A, which is 7.5 A. But in practice, we use the nearest standard size of overcurrent protection device below the ampacity after derating, which usually brings us to either 7 or 5 amperes. Options 10 A and 15 A would be too high and disregard the need for derating. Thus, the most accurate answer, based on NEC guidelines, would likely be 7 A. Still, official guidelines and local regulations should be consulted to determine the exact ampacity as it may vary based on specific conditions.
Based on the NEC guidelines, the ampacity for No. 12 aluminum wire with RHW insulation must be derated when in a raceway with multiple wires. Normally, it is 15 A, but with 20 wires, it would typically be derated to 80%, which closest matches option A, 7 A.
The ampacity of a No. 12 aluminum wire with RHW insulation installed in a raceway with other wires will be de-rated according to the National Electrical Code (NEC). The NEC provides a table for the allowable ampacities of conductors, but they must be adjusted when multiple conductors are bundled together, as they generate more heat and can handle less current.
For No. 12 aluminum wire with RHW insulation, the typical ampacity is 15 A when not in a bundle. However, the NEC states that for more than 3 wires in a conduit, the ampacity must be derated to 80% of this value. Since there are a total of 20 wires in this case, the ampacity would have to be derated further.
Unfortunately, the question does not provide the exact de-rating factor needed for a bundle of 20 wires; the NEC must be consulted directly for specific de-rating factors. Nevertheless, the closest answer from the provided options, based on the typical 80% de-rate, would be 7 A (Answer A).
Access points take ________ from wireless devices and send them on to devices on the wired lan.
E-mail is ________ communication, which means users do not have to communicate at the same time.
Answer: Asynchronous
Explanation:
Asynchronous communication is not based on clock signal rather the communication takes place in non -regular manner by specific synchronized clock.Texting, blogging, vlogging,emailing etc are the examples of asynchronous communication.This can take place from different place at any time.Therefore, E-mail is example of asynchronous communication which permits user to communicate through mails at any point of time
