Answer:
Used for everything from accessing the internet or printing a document to downloading an attachment from an email, networks are the backbone of business today. They can refer to a small handful of devices within a single room to millions of devices spread across the entire globe, and can be defined based on purpose and/or size.
We put together this handy reference guide to explain the types of networks in use today, and what they’re used for.
11 Types of Networks in Use Today
1. Personal Area Network (PAN)
The smallest and most basic type of network, a PAN is made up of a wireless modem, a computer or two, phones, printers, tablets, etc., and revolves around one person in one building. These types of networks are typically found in small offices or residences, and are managed by one person or organization from a single device.
2. Local Area Network (LAN)
We’re confident that you’ve heard of these types of networks before – LANs are the most frequently discussed networks, one of the most common, one of the most original and one of the simplest types of networks. LANs connect groups of computers and low-voltage devices together across short distances (within a building or between a group of two or three buildings in close proximity to each other) to share information and resources. Enterprises typically manage and maintain LANs.
Using routers, LANs can connect to wide area networks (WANs, explained below) to rapidly and safely transfer data.
3. Wireless Local Area Network (WLAN)
Functioning like a LAN, WLANs make use of wireless network technology, such as Wi-Fi. Typically seen in the same types of applications as LANs, these types of networks don’t require that devices rely on physical cables to connect to the network.
4. Campus Area Network (CAN)
Larger than LANs, but smaller than metropolitan area networks (MANs, explained below), these types of networks are typically seen in universities, large K-12 school districts or small businesses. They can be spread across several buildings that are fairly close to each other so users can share resources.
5. Metropolitan Area Network (MAN)
These types of networks are larger than LANs but smaller than WANs – and incorporate elements from both types of networks. MANs span an entire geographic area (typically a town or city, but sometimes a campus). Ownership and maintenance is handled by either a single person or company (a local council, a large company, etc.).
6. Wide Area Network (WAN)
Slightly more complex than a LAN, a WAN connects computers together across longer physical distances. This allows computers and low-voltage devices to be remotely connected to each other over one large network to communicate even when they’re miles apart.
The Internet is the most basic example of a WAN, connecting all computers together around the world. Because of a WAN’s vast reach, it is typically owned and maintained by multiple administrators or the public.
7. Storage-Area Network (SAN)
As a dedicated high-speed network that connects shared pools of storage devices to several servers, these types of networks don’t rely on a LAN or WAN. Instead, they move storage resources away from the network and place them into their own high-performance network. SANs can be accessed in the same fashion as a drive attached to a server. Types of storage-area networks include converged, virtual and unified SANs.
8. System-Area Network (also known as SAN)
This term is fairly new within the past two decades. It is used to explain a relatively local network that is designed to provide high-speed connection in server-to-server applications (cluster environments), storage area networks (called “SANs” as well) and processor-to-processor applications. The computers connected on a SAN operate as a single system at very high speeds.
9. Passive Optical Local Area Network (POLAN)
As an alternative to traditional switch-based Ethernet LANs, POLAN technology can be integrated into structured cabling to overcome concerns about supporting traditional Ethernet protocols and network applications such as PoE (Power over Ethernet). A point-to-multipoint LAN architecture, POLAN uses optical splitters to split an optical signal from one strand of singlemode optical fiber into multiple signals to serve users and devices.
10. Enterprise Private Network (EPN)
These types of networks are built and owned by businesses that want to securely connect its various locations to share computer resources.
11. Virtual Private Network (VPN)
By extending a private network across the Internet, a VPN lets its users send and receive data as if their devices were connected to the private network – even if they’re not. Through a virtual point-to-point connection, users can access a private network remotely.

The advantage of returning a structure type from a function when compared to returning a fundamental type is that a. the function can return multiple values b. the function can return an object c. the function doesn’t need to include a return statement d. all of the above e. a and b only
Answer:
The advantage of returning a structure type from a function when compared to returning a fundamental type is that
e. a and b only.
Explanation:
One advantage of returning a structure type from a function vis-a-vis returning a fundamental type is that the function can return multiple values. The second advantage is that the function can return can an object. This implies that a function in a structure type can be passed from one function to another.

Copy the code above into your program but write all the other code for this assignment yourself. Do not copy any code from another source.
Write a function called has_duplicates that takes a string parameter and returns True if the string has any repeated characters. Otherwise, it should return False.
Implement has_duplicates by creating a histogram using the histogram function above. Your implementation should use the counts in the histogram to decide if there are any duplicates.
Write a loop over the strings in the provided test_dups list. Print each string in the list and whether or not it has any duplicates based on the return value of has_duplicates for that string. For example, the output for "aaa" and "abc" would be the following.
aaa has duplicates
abc has no duplicates
Print a line like one of the above for each of the strings in test_dups.

In the welding operations of a bicycle manufacturer, a bike frame has a long flow time. The set up for the bike frame is a 7 hour long operation. After the setup, the processing takes 6 hour(s). Finally, the bike frame waits in a storage space for 7 hours before sold. Determine the value-added percentage of the flow time for this bike frame. Round your answer to the nearest whole number for percentage and do NOT include the "%" sign in the answer. For example, if your answer is 17.7%, please answer 18. If your answer is 17.4%, please answer 17. No "%" sign. No letter. No symbols. No explanation. Just an integer number.
Answer:
Bike Frame Flow Time
The value-added percentage of the flow time for this bike frame is:
= 46.
Explanation:
a) Data and Calculations:
Bike Frame Flow Time:
Setup time = 7 hours
Processing time = 6 hours
Storage time = 7 hours
Flow time of the bike frame = 13 hours (7 + 6)
Value-added percentage of the flow time for this bike frame = 6/13 * 100
= 46%
b) Flow time represents the amount of time a bicycle frame spends in the manufacturing process from setup to end. It is called the total processing time. Unless there is one path through the process, the flow time equals the length of the longest process path. The storage time is not included in the flow time since it is not a manufacturing process.

Page scaling mode helps increase or reduce the size of the worksheet to fit within the set number of pages to be printed. Which option re-scales
a worksheet vertically?
To re-scale a worksheet vertically, select the number of pages in the height text box in the____group.
Answer:
Scale to fit.
Explanation:
The scale to fit group can be found in the page layout tab as it is used to deal with display of functionalities of a document and spreadsheet program. The scale to fit requires input in the width option which will dictate the width of the page in which to place the documents on. By specifying 1 for the width, this means that the document will be rescaled to fit on a single page. The automatic option may be selected for the height option which will allow the program to make an auto Decison in the shrinkage depending on the stated width value.

. In the select algorithm that finds the median we divide the input elements into groups of 5. Will the algorithm work in linear time if we divide it into groups of 7? How about 3? Explain your answer--- the asymptotic run time in either case.
Answer:
we have that it grows more quickly than linear.
Explanation:
It will still work if they are divided into groups of 77, because we will still know that the median of medians is less than at least 44 elements from half of the \lceil n / 7 \rceil⌈n/7⌉ groups, so, it is greater than roughly 4n / 144n/14 of the elements.
Similarly, it is less than roughly 4n / 144n/14 of the elements. So, we are never calling it recursively on more than 10n / 1410n/14 elements. T(n) \le T(n / 7) + T(10n / 14) + O(n)T(n)≤T(n/7)+T(10n/14)+O(n). So, we can show by substitution this is linear.
We guess T(n) < cnT(n)<cn for n < kn<k. Then, for m \ge km≥k,
\begin{aligned} T(m) & \le T(m / 7) + T(10m / 14) + O(m) \\ & \le cm(1 / 7 + 10 / 14) + O(m), \end{aligned}
T(m)
≤T(m/7)+T(10m/14)+O(m)
≤cm(1/7+10/14)+O(m),
therefore, as long as we have that the constant hidden in the big-Oh notation is less than c / 7c/7, we have the desired result.
Suppose now that we use groups of size 33 instead. So, For similar reasons, we have that the recurrence we are able to get is T(n) = T(\lceil n / 3 \rceil) + T(4n / 6) + O(n) \ge T(n / 3) + T(2n / 3) + O(n)T(n)=T(⌈n/3⌉)+T(4n/6)+O(n)≥T(n/3)+T(2n/3)+O(n) So, we will show it is \ge cn \lg n≥cnlgn.
\begin{aligned} T(m) & \ge c(m / 3)\lg (m / 3) + c(2m / 3) \lg (2m / 3) + O(m) \\ & \ge cm\lg m + O(m), \end{aligned}
T(m)
≥c(m/3)lg(m/3)+c(2m/3)lg(2m/3)+O(m)
≥cmlgm+O(m),
therefore, we have that it grows more quickly than linear.
