Write a recursive function called sum_values that takes in a list of integers and an index of one element in the list and returns the sum of all values/elements in the list starting with the element with the provided index and ending with the last element in the list.
Answer:
Explanation:
The following code is written in the Java programming language and actually takes in three parameters, the first is the list with all of the int values. The second parameter is the starting point where the adding needs to start. Lastly is the int finalSum which is the variable where the values are all going to be added in order to calculate a final int value. Once the recursive function finishes going through the list it exits the function and prints out the finalSum value.
public static void sum_Values(ArrayList<Integer> myList, int startingPoint, int finalSum) {
if (myList.size() == startingPoint) {
System.out.println(finalSum);
return;
} else {
finalSum += myList.get(startingPoint);
sum_Values(myList, startingPoint+1, finalSum);
}
}

Memory compression is a useful alternative to paging:_______.
a. when the compression algorithm is can achieve the best possible compression ratio.
b. when the system has slow magnetic disks but not faster SSDs.
c. when the speed of the compression algorithm fastest.
d. even when the system has faster SSDs.
Answer:
d. even when the system has faster SSDs.
Explanation:
Given that Memory compression and Paging are both means of performing memory management in different ways.
However, Memory compression is a useful alternative to paging "even when the system has faster SSDs."
This is because Memory compression enhances the productivity of Radom Access Memory, RAM, which in turn increases the performance level of a computer.
Also, paging requires consistent writing on Disks, which has been found to degrade disks most especially solid-state drives, SSDs.

The type of wireless access that uses a modem to connect to cell towers is called ___
broadband.
Answer:
What are the Wireless Broadband Technologies?
What are the Wireless Broadband Technologies?
Wireless broadband services are similar to wired broadband in that they connect to an internet backbone usually a fiber-optic trunk; however they don’t use cables to connect to the last mile or business/residences. Instead they use Wireless Fidelity (Wi-Fi) connections or radio waves. A computer or mobile device has a wireless adapter that translates data into a radio signal and transmits the signal using an antenna. A wireless router receives the signal, decodes it and then sends it to the Internet through a wired Ethernet connection.
Fixed wireless is a type of high-speed Internet access where connections to service providers use radio signals rather than cables. Fixed wireless offers connections speeds between 1 and 10 mbps and use transmission towers similar to cell phone towers that communicate to a resident’s transceiver equipment that, as the name implies is fixed at the premise. The transceiver equipment communicates with the providers’ ground stations.
Wireless fidelity (Wi-Fi) is a fixed, short-range technology that is often used in combination with DSL, fixed wireless, fiber, or cable modem service to connect devices within a home or business to the Internet using a radio link between the location and the service provider’s facility. Wi-Fi service can be available in your home or at community locations (airports, coffee shops, schools, businesses, etc.) and are often called “hotspots.” A Wi-Fi network uses radio waves, similar to two-way radio communications. A computer has a wireless adapter that translates data into a radio signal and transmits it using an antenna. A router receives the signal, decodes it, and then sends the information to the Internet using a physical connection, usually via an Ethernet cable, a cable that carries the broadband signal between the modem, router, computer, and other wired Internet capable devices.
Mobile Wireless (3G, 4G)
Mobile wireless is high-speed wireless broadband connection that is accessible from random locations. The locations depend on the provider’s cellular towers and monthly service plans. Many technologies make up wireless networks, but no matter the technology or acronyms you read or hear, mobile wireless networks are radio systems.
Mobile wireless services are continually being upgraded to provide data transmission speeds considered to be broadband. The faster mobile wireless networks are referred to as 3G or 4G.The “G” stands for “generation,” meaning 3rd and 4th generation or the evolution of broadband cellular networks; supposedly, each generation provides a faster more secure wireless network. A mobile wireless service requires a base station that is connected to a high capacity landline data transmission network to reach the Internet. In other words, it’s never wired OR wireless; ultimately, it has to be both. Wireless broadband in common usage means that the so-called “last mile” connection to the user is done via radio signals from a tower to a cell phone or other wireless devices (e.g., a tablet).
Long Term Evolution (LTE)
LTE is a 4G technology provides increased peak data rates, reduced latency, scalable bandwidth capacity than 4G predecessors. LTE can manage multi-cast and broadcast streams and handle quick-moving mobile phones. It uses an IP-based network architecture that allows for seamless handovers for voice and data to older model cell towers.
Satellite
Satellite broadband is sometimes the only option available to users in very rural or sparsely populated areas. Like telephone and television services, satellites orbiting the earth provide necessary links for broadband. With satellite service, you must have a clear view of the southern sky. Satellite service can be disrupted by weather conditions and changes in line of sight to the orbiting satellite. Satellite may have a higher monthly service charge than other broadband options and the need to purchase more home or business equipment compared to the other options. Because satellites are located a significant distance from customers, there are issues of “latency” and therefore a noticeable time lag between sending and receiving data by the end customer.
Downstream and upstream speeds for satellite broadband depend on several factors, including the provider and service package purchased the consumer’s line of sight to the orbiting satellite, and the weather. Satellite speeds may be slower than DSL and cable modem, but they can be about 10 times faster than the download speed with dial-up Internet access. Service can be disrupted in extreme weather conditions.

HP Deskjet 2630.Microsoft Windows 10 (32-bit)Write code that creates a text area displaying 10 rows and 15 columns. The text area should be capable of displaying scroll bars, when necessary. It should also perform word style line wrapping.
Answer:
<textarea wrap="hard" cols="30" rows="5"></textarea>
Explanation:
A textarea element or tag is a form tag element of a HTML file. It is used to ask for input value from a user in a webpage. The textarea tag has an opening and a closing tag.
The 'cols' attribute is used to set the column length while the 'rows' attribute sets the row length of the textarea element. The 'wrap' attribute has three options namely; soft, hard, and off. 'soft' adds the textarea wrapping, 'hard' sets off the box wrapping but only wraps each line, while the 'off' option removes all wrapping in the tag.

A boundary marks the inside and outside of a system and sets the system apart from its environment.
A. True
B. False
Answer:
True
Explanation:
The system boundary can be regarded as a conceptual line that demacate
the system that is under study from 'everything else'. which is the environment. The environment consist of things that can influence the system but not part of the system. when the system is small , its boundary will be sharper. Some Large systems usually have multiple boundaries.boundary can as well be regarded as the point of contact which gives room for meeting between a system its environment , it is also point subsystems meet each other. It should be noted that boundary marks the inside and outside of a system and sets the system apart from its environment.

How do I fix my mistake in the code, do not give me a bs answer like “I don’t know sorry” if you do not know just move on because I will report it like I have before.
The problem lies within your if statement. You're using a single equals sign when you should be using two.
if (operation == 1)
Two equal signs is a comparison operator. It checks to see if one value equals another value. In your case, its checking if operation equals 1. But, this only solves half the problem. Operation is a string and you need to compare it to a string.
if (operation == "1")
