True; synchronous means existing or occurring at the same time (I really don't know if that's a question but oh well)

What additional features on your router would you implement if you were setting up a small wired and wireless network
olganol [36]

Answer:

Explanation: The following features will be implemented:

1) Guest networks,

2) Networked attached storage,

3) MAC filtering

A guest Wi-Fi network is essentially a separate access point on your router. All of your home gadgets are connected to one point and joined as a network, and the guest network is a different point that provides access to the Internet, but not to your home network. As the name implies, it's for guests to connect to.

Network Attached Storage

is dedicated file storage that enables multiple users and heterogeneous client devices to retrieve data from centralized disk capacity. Users on a local area network (LAN) access the shared storage via a standard Ethernet connection.

MAC address filtering allows you to define a list of devices and only allow those devices on your Wi-Fi network.

Angelina_Jolie [31]

Explanation:

Emily solved for a part when she should have solved for the whole. 875,000 should be the numerator of the equivalent ratio. 70 x 12,500 is 875,000. So the answer is 100 x 12,500 which is 1,250,000.

enot [183]

Answer:

a. Programmed decisions

Explanation:

We basically have two types of decision:

  • Programmed decision
  • Non-Programmed decision

Programmed Decision: used for frequent situations of the organization; both internal and external. This decision results in the formulation of rules, procedures, and policies that can be applied in the future.

Non-Programmed Decision: used for unique and ill-structured situations of the organization; both internal and external. They are one-shot decisions. They have been handled by techniques such as judgment, intuition, and creativity.

1. Extract title Write a function extract_title that takes one parameter, the filename of a GenBank formatted file, and returns
trapecia [35]

Answer:

def extract_title(file):

   import re

   a =''

   with open(file,'r') as file:

       for line in file:

           a += line

       m = re.search("^(TITLE)(.*?)(JOURNAL)", a, re.M + re.S)

       print(m.groups()[1])

extract_title('new.txt')

Explanation:

The programming language used is python 3.

The function is first defined and the regular expression module is imported.

A variable is initialized to an empty string that will hold the content of the GenBank formatted file.

The file is opened and every line in the file is assigned to the string variable. The WITH statement allows files to be closed automatically.

Regular expression is used to capture all the files between TITLE and JOURNAL in a group.

The group is printed and the function is called.

I have attached a picture of the code in action.

Write a function called count_occurrences that takes two strings. The second string should only be one character long. The funct
iVinArrow [24]

Answer:

Here is the Python function:

def count_occurrences (string1 , string2):  # method that takes two strings as parameter and returns how many times second string occurs in first

   count = 0  #counts number of occurrence of string2 in string1

   for word in string1:  #iterates through each word of the string1

       for character in word:  #iterates through each character of each word in string1

           if character == string2:  # checks if the character in string1 is equal to the character of string2

               count = count + 1  #adds 1 to the count of string2 in string1

   return count  #returns number of times the string2 occurs in string1

#in order to check the working of the function add the following lines to the code:    

first_str = input("Enter the first string: ")  #prompts user to enter first string

second_str = input("Enter the second string (one character long): ") #prompts user to enter second string which should be one character long

occurrence = count_occurrences(first_str,second_str)  #calls count_occurrences method by passing both strings to it

print(second_str,"occurs",occurrence,"times in",first_str) #prints how many times the second_str occurs in the first_str on output screen

Explanation:

The program is well explained in the comments added to each statement of the above code. I will explain the program with an example:

Suppose

string1 = "hello world"

string2 = 'l'

So the method count_occurrences() should return how many times l occurs in hello world.

count is used to count the number of occurrences of l in hello world. It is initialized to 0.

The first loop iterates through each word of string1. The first word of string1 is "hello"

The second loop iterates through each character/letter of each word. So the first letter of "hello" word is 'h'.

The if condition if character == string2: checks if the character is equal to string2 i.e. l.

character = "h"

string2 = "l"

The are not equal so the program moves to the next character of word hello which is e. The if condition again evaluates to false because e is not equal to l. So the program moves to the next character of word hello which is l.

This time the if condition evaluates to true because

character = "l"

string2 = "l"

character == string2

l == l

So the if part is executed which has the following statement:

count = count + 1

So the count is added to 1. count was 0 previously. Now

count = 1

Next the program moves to the next character of word hello which is l. This time the if condition evaluates to true because the character l matches with string2. So count is again incremented to 1. count = 2.

Next the program moves to the next character of word hello which is o. The if condition evaluates to false as o does not match with string2 i.e. l. So the count remains 2.

Next the first loop moves to the next word of the string1 = "world". The inner (second) for loop iterates through each character of "world" from "w" to "d" and checks if any character is equal to string2. Only one character is equal to string2 in "world". So count is incremented to 1. Hence count = 3

After the loop ends the statement return count returns the number of times string2 occurs in the string1. So the output is:

l occurs 3 times in hello world
