Answer:
The capacity of the disk is "40 GB".
Explanation:
Given value:
[tex]\to \text{cylinder}= 10,000\\\\\to \frac{sector}{track} = 400\\\\\to \frac{bytes}{sector} = 512\\[/tex]
[tex]\text{Calculating the size of track} = \frac{bytes}{sector} \times \frac{sector}{track}[/tex]
[tex]= 512 \times 400 \\\\ = 204,800 \ \ Or \ \ 200 \ K[/tex]
[tex]\text{Calculating the size of surface} = \frac{byte}{track} \times \ cylinder[/tex]
[tex]= 2000 \ K \times 10,000 \\\\ = 20, 000,000 \ K[/tex]
[tex]\text{Calculating the capacity of a disk} = \frac{byte}{surface} \times \frac{surface}{disk}[/tex]
[tex]= 20, 000,000 \ K \times 2 \\\\ = 40, 000,000 \ K \\\\= 40 \ GB[/tex]
Cache memory is often used to speed up the runtime. It will enable us to improve performance unless we can store information, that is retrieved constantly in memory space.
Hit Cache: when the Processor relates to representing database data, Cache Hit results. Miss Cache: when this Processor responds to a non-present cache data, this will trigger its miss of cache.It doesn't have to retrieve the Main Memory through secondary storage.Which statement is true? A. Pseudocode uses shapes such as rectangles and diamonds to plan a program. B. You only use comments for pseudo code. C. A flowchart uses comments that can be kept as a permanent part of a program. D. A comment line begins with # Please hurry also you can only choose one answer so idk which one thank you
Answer:
D) A comment line begins with #
Explanation:
Comments are used in programming to explain what a line or block of code is doing.
It helps the programmer easily remember what their code was about when they come back to it having left it for a while.
Also comments help other programmers understand code written by one programmer.
A comment or an in-line comment usually begins with #. That way the computer skips it and doesn't regard it as a line of code.
Answer: D. A comment line begins with #.
Explanation:
In the text, it stated, "The easiest way to add a comment is to start the line with the pound sign (#)."
(Comments are notes that allow you to write anything without affecting the code itself. Comments can be utilized to indicate when and how you later changed a program, and provide a description of the changes.)

Explain why the expected value of an F ratio is 1.00 when the null hypothesis is true if there is no treatment effect the numerator.
Answer:
The reason is that the f ratio is balanced due to the numerator and denominator having equal sources of variability.
Explanation:
The expected value of an F ratio is 1.00 when the null hypothesis is true because in a scenario where there is no treatment effect, we have both the numerator and the denominator of the F ratio both measuring equal sources of variability.
Whenever this happens then the F ratio will be balanced and also it will have a value that is near 1.00.

Explanation:
correct answer edge 2020
# the main part of your program that calls the function poem() userWord and rhymeWord. Hence, option C is correct.
What is rhymeWord?Rhyming words all have the same last consonant. Simply put, it is the repetition of similar sounds. When two words have similar sounds, usually those that follow the final stressed syllable of each word, the words are said to rhyme. Cat-hat, rotten-forgotten, and heard-bird are some examples of words that rhyme; they all have similar sounds after the final stressed syllable.
If the last sounds of two or more words are the same or similar, then the words will rhyme. Some words that rhyme are goat, boat, moat, float, and coat. To determine whether two words rhyme, use your ears to listen while you speak the words. If two words have a similar or matching sound, they rhyme.
Thus, option C is correct.

what product and service type should I choose in quickbooks online if I do not want to track inventory
Answer:
is that what you're looking for
In QuickBooks Online, it’s easy to track how much you make and spend on each product or service. You can also enter these products and services you sell as items so you can quickly add them to sales forms. This gives you more detailed financial reports and helps you complete transactions faster.
Here's how to add services and products you don't plan to track inventory for (also known as non-inventory items).
Note: If you want to track product quantities, add them as inventory items instead.
Answer:
Non-inventory: Products or items you buy or sell, but don't need to track quantities. For example, nuts and bolts you use for installation jobs but don't sell directly.
Using the programming language of your choice, implement the Binary Search algorithm for a target value = 9 on the Array A: [9, 11, 70, 25, 20, 0, 36, 24]. What is the primary condition to implement a Binary Search Algorithm? Explain the growth rate of the algorithm
Answer:
myArray = [9, 11, 70, 25, 20, 0, 36, 24]
myvalue = 20
def binary_search(mylist, value):
sorted(mylist)
mid = mylist[round(len(mylist) / 2)]
if value == mid:
return mylist.index(mid)
elif value < mid:
for index, s_one in enumerate(mylist[ : (mylist.index(mid))]):
if s_one == value:

If process P0 is switched to process P1, state for P0 will be saved into ____, and state from ___ will be reloaded.
Answer:
1. PCB0
2. PCB1
Explanation:
Given that PCB is often referred to as Process Control Block, is a form of data structure that is applicable and utilized by the computer operating systems to store all the information concerning a process.
This process is carried out in a way that when Process P0 is initialized, the operating system established a related process that takes the computer processing unit from Process P0 and allocates it to Process P1, the Operating System, in turn, will save P0's PCB, and then reload P1's PCB.
Hence, If process P0 is switched to process P1, the state for P0 will be saved into "PCB0" and the state from "PCB1" will be reloaded.

You use the same five shell functions every day and are looking for a way to ensure they are available as soon as you log into your account. What can you do?a. Make them residual system variables.b. Make them permanent environment variables.c. Load them via your login script.d. Make them permanent functions by adding them to the function directory.
Answer:
.c. Load them via your login script.
Explanation:
Given that using functions in shell scripts enhances programming output and login script comprises the functions and statements required to effectively execute at any given time the user logs into their account.
Hence the moment these functions are formulated, they are then executed through a single command statement thereby reducing the time of re-writing another set of code repeatedly in every program.
Therefore, in this case, what you can do is to "Load them via your login script."

How is a UDP socket fully identified? What about a TCP socket? What is the difference between the full identification of both sockets?
Answer:
Following are the solution to this question:
Explanation:
Two tuples were fully identified only with UDP socket.:
< IP address assigned, the port for destination >
Its two tuples have been used in UDP as demux, buttons to identify its UDP socket.
The IP address for the destination:
Its received data is directly provided by the IP address of its port.
Port number of the destination:
The function of the IP address of its port number whenever you obtain a UDP segment would be to control the IP addresses of a segment or send that segment to a port with the same IP address. Its port number for endpoint allows demultiplexing incoming information from its IP.
TCP socket is completely recognized by the following four tuples:
< source IP, port source, IP source, port location >
It tuples are being used to label the sockets by using a demultiplexing (demux) key.
IP address source:
The IP address is being used to identify the unique host that links to. It can assume that perhaps the source IP address shows us all the source Addresses of the sender.
Port number of source:
Its port number amount allows us to identify which section is arriving at which port.
IP address destination:
Its IP address of a destination is the IP address of a port accepting incoming information.
Port number of the destination:
It is port numbers number allows us to identify the facilities or section should be sent to.
Differentiation between TCP and UDP identifier:
As TCP ports (4 tuples) and UDP ports (2 tuples) are using demux keys to define socks, however, demux keys in UDP are unique from others in TCP for both the following reasons:
TCP uses a separate socket for every contact between both the server and client whereas UDP utilizes its same sockets to process all clients accessed by UDP servers with all communications, it maintains TCP is much more dependable and hence has to hold a different port.
Even so, UDP doesn't accomplish things apart from multicasting and demodulation, but no separate port is necessary by each link. Therefore the TCP socket becomes connection-driven as well as the UDP socket is direct link-free.
There are different ways' to identify the Socket. The presence or absence of a connection needs that the identifier format of each socket are known to be very different.
The TCP socket is identified by the quadruple. This includes;
Source IP addressSource port numberDestination IP addressDestination port numberAn UDP socket is identified by the tuple such as
Destination IP addressDestination port number
There are some difference between TCP socket and UDP socket. They are;
TCP is known to be a connection-oriented protocol but the UDP is a connectionless protocol. Another difference between TCP and UDP is speed. TCP is said to be slower than UDP. UDP is said to be faster, simpler, and efficient protocol than TCP.

Determine if the input numbers are Armstrong numbers. Input: Your program should read lines from standard input. Each line has a positive integer. Output: Print out True if the number is an Armstrong number, or False if not. Test 1 Test Input 351 Expected Output False
Answer:
Written in Python
number = int(input("Enter a number: "))
computesum = 0
lent = len(str(number))
for digit in str(number):
computesum += int(digit)**lent
if number == computesum:
print("true")
else:
print("false")
Explanation:
This line prompts user for Input input
number = int(input("Enter a number: "))
This line initialises the sum of the nth power of the digits to 0
computesum = 0
This line gets the length of input (i.e. number of digits)
lent = len(str(number))
The following iteration iterates through the digit to check for Armstrong numbers
for digit in str(number):
computesum += int(digit)**lent
This checks if the input number equals the computed sum
if number == computesum:
print("true") --- if yes, "true" is printed
else:
print("false") --- if otherwise, "false" is printed

During periods when the internet is not slowed by congestion, the number of internet searches is probably close to the socially efficient number. how can we tell this this is true?
Answer:
We can this is true because the number of internet searches that are being done at that time is just enough to meet the actual capacity of the internet facility.
Explanation: Socially efficient number is that number that is just enough to meet the actual capacity of a given system such as an internet connectivity or internet facility.
When the number of internet searches are just enough not to cause congestion in the search engines or internet facility,it can be said that the socially efficient number has been achieved.

Explanation:
Clyde Clerk is reviewing his firm’s expense reimbursement policies with the new salesperson, Trav Farr. "Our reimbursement policies depend on the situation. You see, first we determine if it is a local trip. If it is, we only pay mileage of 18.5 cents a mile. If the trip was a one-day trip, we pay mileage and then check the times of departure and return. To be reimbursed for breakfast, you must leave by 7:00 a.m., lunch by 11:00 a.m., and have dinner by 5:00 p.m. To receive reimbursement for breakfast, you must return later than 10:00 a.m., lunch later than 2:00 p.m., and have dinner by 7:00 p.m. On a trip lasting more than one day, we allow hotel, taxi, and airfare, as well as meal allowances. The same times apply for meal expenses." Write structured English for Clyde’s narrative of the reimbursement policies. Draw a decision tree.
Answer:
The answer is described in the image.
Explanation:
The firm is responsible for all expenses made by it's employees, so for a local trip, the cost of gas relative to the mileage covered during the journey is paid for ( 18 cents per mileage).
If it is not a local trip, then it is a one-day trip, so the firm pays for the mileage and the cost of the meals not taken in the company, which depends on the departure and return/arrival time. If the departure and return time is 7am to 10am, the employee is paid for breakfast, if the departure and return is 11am to 2pm then the employee is paid for lunch, and for dinner, 5pm to 7pm.
