While interoperability and unrestricted connectivity is an important trend in networking, the reality is that many diverse systems with different hardware and software exist. Programming that serves to "glue together" or mediate between two separate and usually already existing programs is known as:
Answer:
Middleware
Explanation:
In today's technology like networking, software development, web development, etc, there is a need for connectivity. The problem at hand is the variation of the tech brands which results in the difference in operating systems, applications, and connectivity protocols. This problem is solved with the introduction of Middleware.
Middleware is the solution to conflicting software applications, interconnectivity between various tech platforms. It promotes cross-platform interactions.
Why operating system is pivotal in teaching and learning
Answer:
Without it information flow is impossible
Explanation:
The word 'pivotal' also means crucial or vital, and so we need to consider what an operating system actually does.
Remember, merely having all the hardware of a computer would not allow you to run (install and use) programs. It is by means of an operating system that teaching programs can be installed, and it is also by means of an operating system learning can take place.
For example, a student can decode (learn) instructions/lessons from his teacher via a software program; and the software program needs an operating system to open (run) the program.

The first electric, general-purpose computer, ENIAC, was programmed by calculating algorithms on paper entering code directly into the computer flipping switches by hand using MS-DOS as the operating system
Complete Question:
The first electric, general-purpose computer, ENIAC, was programmed by?
Group of answer choices.
A. Calculating algorithms on paper.
B. Entering code directly into the computer.
C. Flipping switches by hand.
D. Using MS-DOS as the operating system.
Answer:
C. Flipping switches by hand.
Explanation:
The first electric, general-purpose computer, ENIAC, was programmed by flipping switches by hand.
ENIAC is an acronym for Electronic Numerical Integrator and Computer, it was developed in 1945 by John Mauchly and J. Presber Eckert. ENIAC was used for solving numerical problems or calculation-related tasks by the process of reprogramming.
In order to give the ENIAC a series of machine instructions to follow in the execution of a task, the programmers had to undergo the cumbersome procedure of connecting, removing, reconnecting cables and flipping switches by hand because data couldn't be stored in memory.
the base on which the number n=(34)? is written if it has a value of n= (22)10
If I'm understanding the question correctly, you are looking for an integer b (b ≠ 0, b ≠ 1) such that
[tex]34_b = 22_{10}[/tex]
In other words, you're solving for b such that
3×b ¹ + 4×b ⁰ = 22
or
3b + 4 = 22
Solving this is trivial:
3b + 4 = 22
3b = 18
b = 6
So we have
34₆ = 22₁₀
Review the given requirements using the checklist and discover possible problems with them. The following requirements are for a library system which is an interactive system providing access to a large document database and which allows the automated ordering and electronic delivery of documents to local and remote end-users. Some requirements for this system are: Req. 1 The user interface shall be html. Users shall access the system via standard web browsers such as Netscape and Internet Explorer. Req. 2 The system shall primarily an end-user system. Users shall use the system within the constraints of the permissions assigned by the administrator to identify, locate, order and receive documents. Req. 3 Users shall communicate with the system mainly via the html interface. Req. 4 User shall provide input to the system via the html interface. Req. 5 The system shall give output to the user via the html interface, email and print. The print output shall mainly be documents.
Answer:
Redundancy
Req. 1 and Req. 3 are seemed to say the same thing. We need to remove the first sentence in Req. 1
Conflict and understandability
Req. 1 states that access is through web browser while Req. 4 states that access is via html. We have to re-write the Req. 3 to make it clear that users do not actually have to write directly html to communicate with the system.
Completeness
Req. 5 states that print out will “mainly” be documents. What else might be printed? What other inputs will be produced?
Either remove mainly or clarify other print out.
What version of html or web browser is assumed in Req. 1 and Req. 3?

Show using a cross-product construction that the class of regular languages is closed under set difference. You do not need an inductive proof, but you should convincingly explain why your construction works.
Answer:
The class definition for Javascript:
var Class = {
arguments of the class object are initialized here;
}
This class definition for Python:
class "class_name"( object ):
def __init__(self, arguments are passed are and initialized after the closing parenthesis)
Explanation:
Object-oriented programming languages are vital tools in creating data structures that are meant to be changeable, unindexed but directly accessible knowing the key value, and has unique membership.
This clearly is an adoption of the set data structure rule in creating a data structure blueprint that can be instantiated anytime in the code.
Write the program to compute how many gallons of paint are needed to cover the given square feet of walls. Assume 1 gallon can cover 350.0 square feet. So gallons =the square feet divided by 350.0. If the input is 250.0, the output should be: 0.714285714286
Answer:
Here is the Python and C++ program.
Python program:
gallons_paint=0.0 #declare and initialize gallons_paint
wall_area = float(input()) #prompts user to enter wall area
gallons_paint = wall_area / 350 #formula to compute gallons of paint needed to cover the given square feet of walls
print(gallons_paint) #display the result
C++ program:
#include <iostream> //to use input output functions
using namespace std; //to identify objects like cin cout
int main(){ //start of main() function body
float wall_area,gallons_paint=0; //declare variables
cin>>wall_area; //reads input wall area from user
gallons_paint=wall_area/350; //formula to compute gallons of paint needed to cover the given square feet of walls
cout<<gallons_paint;} //print the result
Explanation:
The program prompts the user to enter the area of wall and stores the input value in wall_area
Suppose the user enters 250 as wall area
The the formula gallons_paint=wall_area/350; works as follows:
gallons_paint = wall_area/350;
= 250/350
= 0.71428
gallons_paint = 0.71428
So the output is:
0.71428
The screenshot of the program along with its output is attached.
What is also known as computer Network?
What are the constraints for designing small and large files and how these are resolved in different file system
Answer:
space management and buffering speed.
Explanation:
There are different types of file management systems in a computer system, examples of which are NTFS, FAT, WAFL, etc, and are governed by protocols like NFS, TFTP, FTP, etc.
These file systems are used in storages like the hard disk drive, CD and DVD, solid-state drive, etc, to organize or manage the files from boot setup, device drivers to permission-seasoned user files.
Files in storage range from small to large files, for which the schema of the file system must adjust to manage and allocate free space to other files in the future. The file system is also able to index the location of a file for retrieval to a cache memory, making buffering faster.

A user in an apartment building on a wireless network is no longer able to print to the network printer. The user has been able to print to the printer in the past and nothing on the network has changed. A technician notices that the user has a different IP address scheme than what was originally setup and is able to browse the Internet using that IP address scheme. What should he do?
Answer:
The technician should either provide a route from the user's IP scheme to the printer or change the user's IP scheme to be within the same scheme as the printer.
Explanation:
The most likely reason the user is unable to print to the printer is that the user's computer cannot path the current address to the address of the printer. Without the printer being on the same subnet as the user's computer, the computer has no way of being able to tell where the printer is.
The two solutions to this are to either add a route to the user's computer explicitly telling the user's computer where to trace to find the printer or to change the user's computer to match the IP scheme of the printer.

Write a recursive function sumSquares(num) that given an integer num, returns the sum of squares of numbers from 1 to num. For example: sumSquares(3) should return 1^2 2^2 3^2
Answer:
Here is the recursive function sumSquares(num) that takes an integer num as parameter and returns the sum of squares of numbers from 1 to num.
def sumSquares(num):
if(num >= 0): # checks if the value of num is less than or equal to 0
if (num==0): #if value of num is 0
return 0 #returns 0 if value of num is 0
else: #if value of num is greater than 0
return sumSquares(num - 1)+ num * num #recursively calls the sumSquares method to return the sum of squares of numbers from 1 to num
else: # if a user enters a negative num
(print("The number if not positive")) #prints this message
exit() # exits after displaying that number if not positive message
#below print statement is used in order to check the working of the function
print(sumSquares(3)) #calls function and passes value 3 for num
Explanation:
The program works as follows:
The function sumSquares(num) that takes an integer num as parameter and returns the sum of squares of numbers from 1 to num
The first if condition checks if value of num is positive. If this condition evaluates to true then the another if statement inside this if statement is executed which checks if the value of num is 0. If this condition evaluates to true then the program returns 0. However if this condition evaluates to false then the else part executes which has the following statement:
return sumSquares(num - 1) + num * num
For example num = 3
so the above recursive statement works as follows:
sumSquares(3-1) + 3 * 3
sumSquares(2) + 9
Note that the sumSquares() method is called again and the value 2 is passed as num. As 2 is greater than 0. So again the recursive statement executes:
sumSquares(2 - 1) + 2 * 2 + 9
sumSquares(1) + 4 + 9
sumSquares(1) + 13
sumSquare() method is called again and the value 1 is passed as num. As 1 is greater than 0. So again the recursive statement executes:
sumSquares(1 - 1) + 1 * 1 + 13
sumSquares(0) + 1 + 13
sumSquares(0) + 14
sumSquare() method is called again and the value 0 is passed as num
As the value of num=0 So the if (num == 0): condition evaluates to true and the statement returns 0 executes which returns 0:
sumSquares(0) + 14
0 + 14
Hence the output is:
14
The screenshot of the program along with its output is attached.

Will the Python code below print something? And will it terminate?
def print_n(s, n):
if n > 0:
print(s)
print_n(s, n-1)
return n
n = 3
while print_n("hi", n):
print_n("there!", n)
n = 0
a. no and no
b. yes and no
c. no and yes
d. yes and yes
e. syntax error
Answer:
Yes and Yes
Explanation:
When programs are written without indentation; it becomes a problem to read;
I'll rewrite your program as follows:
def print_n(s, n):
if n > 0:
print(s)
print_n(s, n-1)
return n
n = 3
while print_n("hi", n):
print_n("there!", n)
n = 0
Using the above as a point of reference,
Yes, the program will run and Yes, it'll terminate;
Because n is initialized to 3 at line 6 (where the main starts);
The following is passed to the function; s = "hi" and n=3
This prints "hi", three times
s = "there" and n=3 is then passed to the function print_n, afterwards;
The function then prints "there" three times
Then, the program terminates

A direct-mapped cache holds 64KB of useful data (not including tag or control bits). Assuming that the block size is 32-byte and the address is 32-bit, find the number of bits needed for tag, index, and byte select fields of the address.
Answer:
A) Number of bits for byte = 6 bits
B) number of bits for index = 17 bits
C) number of bits for tag = 15 bits
Explanation:
Given data :
cache size = 64 kB
block size = 32 -byte
block address = 32 -bit
number of blocks in cache memory
cache size / block size = 64 kb / 32 b = 2^11 hence the number of blocks in cache memory = 11 bits = block offset
A) Number of bits for byte
[tex]log _{2} (6)^2[/tex] = 6 bits
B) number of bits for index
block offset + byte number
= 11 + 6 = 17 bits
c ) number of bits for tag
= 32 - number of bits for index
= 32 - 17 = 15 bits
