Apple built the Apple 1 in 1976. The personal computer had a circuit board that was placed into a wooden box, to become the first computer built by Steve Jobs and Steve Wozniak. This was the company’s first personal computer.

Answer:

Apple Computers

Explanation:

In 1976 Apple was founded, with partners Steve Jobs (still active today) and Steve Wozniak, who, while not as well-known as the partner, did almost all the hard work of development. A curiosity is that Apple was only founded because the Apple I project (developed by the two in their spare time) was rejected by Atari and HP.

The Apple I was sold already assembled. The board was sold “naked”, mounted on a wooden board and packed in a cardboard box, so it was common for Apple I to be installed inside handcrafted wooden boxes.

Write a program that takes a single integer input from the user and stores it in a variable. Your program should increase the va

Allushta [10]

Answer:

Question is answered using python:

num = int(input("User Input: "))

for i in range(3):

num = num+1

print("Number is now "+str(num))

for i in range(3):

num = num-1

print("Number is now "+str(num))

Explanation:

This line prompts user for input

num = int(input("User Input: "))

The following iterates from 1 to 3

for i in range(3):

This increments user input each time

num = num+1

This prints the value of num after increment

print("Number is now "+str(num))

The following iterates from 1 to 3

for i in range(3):

This decrements the value of num

num = num-1

This prints the value of num after decrement

print("Number is now "+str(num))

FTP requires confirmation that a file was successfully transmitted to a client, but it has no built-in mechanism to track this i

Sholpan [36]

Answer:

Transmission Control Protocol (TCP)

Explanation:

FTP: FTP stand for File Transfer Protocol. It is an internet protocol for transferring files between computers on a computer network over TCP/IP connections. It is based on client server architecture in which a client asks for a file and the server (local or remote) sends it. FTP uses TCP to ensure all the data packets are transmitted correctly to the proper destination.

Transmission Control Protocol: It is a protocol used in the Transport Layer of the TCP/IP model. The basic role of this layer is to ensure end-to-end delivery of data from the source to the destination. TCP is a connection oriented protocol that works with the Internet Protocol and provides ordered, guaranteed and error free delivery of data from source to destination. This is how application programs communicate and exchange data through an IP network. It is connection oriented protocol means connection between client and server is setup before data transmission. At source host TCP divides streams of bytes in segments. Then it allocates sequence number to each segment. At destination end it reorders the delivered segments. Then it sends an acknowledgment to sender as a signal that the correct segments have been received. TCP also employs error detection that ensure reliability. TCP also manages flow control and congestion control to avoid data packets loss or delay and to ensure that a sender does not send packets faster than the receiver can receive.

In mathematics, the notation n! represents the factorial of the nonnegative integer n. The factorial of n is the product of all

hram777 [196]

Answer:

The program to this question can be given as:

Program:

factorial=1 #declare a variable.

number=int(input("Enter a positive integer:")) #input a number.

while (number>0): #loop

factorial= factorial*number # holding value in factorial variable

number=number-1

print('=',factorial) #print value.

Output:

Enter a positive integer:6

= 720

Explanation:

The description of the above python program can be given as:

In the above program firstly we define a variable that is "factorial". In this variable, we assign a value that is 1 and it is used to calculate the factorial value.
We define a variable "number". The number variable is used to take input from the user.
Then we define a loop in the loop we calculate the factorial and hold the value in the factorial value in the last we print the value.

Recall the problem of finding the number of inversions. As in the text, we are given a sequence of n numbers a1, . . . , an, whi

Kay [80]

Answer:

The algorithm is very similar to the algorithm of counting inversions. The only change is that here we separate the counting of significant inversions from the merge-sort process.

Algorithm:

Let A = (a1, a2, . . . , an).

Function CountSigInv(A[1...n])

if n = 1 return 0; //base case

Let L := A[1...floor(n/2)]; // Get the first half of A

Let R := A[floor(n/2)+1...n]; // Get the second half of A

//Recurse on L. Return B, the sorted L,

//and x, the number of significant inversions in $L$

Let B, x := CountSigInv(L);

Let C, y := CountSigInv(R); //Do the counting of significant split inversions

Let i := 1;

Let j := 1;

Let z := 0;

// to count the number of significant split inversions while(i <= length(B) and j <= length(C)) if(B[i] > 2*C[j]) z += length(B)-i+1; j += 1; else i += 1;

//the normal merge-sort process i := 1; j := 1;

//the sorted A to be output Let D[1...n] be an array of length n, and every entry is initialized with 0; for k = 1 to n if B[i] < C[j] D[k] = B[i]; i += 1; else D[k] = C[j]; j += 1; return D, (x + y + z);

Runtime Analysis: At each level, both the counting of significant split inversions and the normal merge-sort process take O(n) time, because we take a linear scan in both cases. Also, at each level, we break the problem into two subproblems and the size of each subproblem is n/2. Hence, the recurrence relation is T(n) = 2T(n/2) + O(n). So in total, the time complexity is O(n log n).
