Task 1:

float75 = float(75)

string75 = "75"

# you cannot add together a number and a string because a string has no inherent numerical value like a number does.

Task 2:

num = float(input("Enter a number"))

print(num**2)

Task 3:

num = int(input("Enter an integer: "))

print("When you divide "+str(num)+" by 7, the quotient is "+str(num//7)+" and the remainder is "+str(num%7)+".")

Task 4:

gigs = int(input("How many gigabytes does your flashdrive hold? "))

print("A flashdrive with "+str(gigs)+ " gigabyte(s) holds "+str(gigs*8589934592)+" bit(s).")

For task 4, you might have to change the number 8589934592 to something else. I'm not entirely sure how many bits are in a gigabyte. I hope this helps though.

Different types of connections are..

-A network is two or more devices connected through links.

-There are two possible types of connections: point-to-point and multipoint.

-A point-to-point connection provides a dedicated link between two devices.

Explain the different types of topologies

-Star network…
In star topology each device in the network is connected to a central device called hub. Unlike Mesh topology, star topology doesn't allow direct communication.

-Ring network…
A number of repeaters are used for Ring topology with large number of nodes, because if someone wants to send some data to the last node in the ring topology

-Bus network…
In bus topology there is a main cable and all the devices are connected to this main cable through drop lines. There is a device called tap that connects the drop

-tree topology…
Tree topologies have a root node, and all other nodes are connected which form a hierarchy. So it is also known as hierarchical topology. This topology integrates

Different type of networks

-Computer network…
Virtual Private Network (VPN). By extending a private network across the Internet, a VPN lets its users send and receive data.

-LAN…
Using routers, LANs can connect to wide area networks (WANs, explained below) to rapidly and safely transfer data. 3. Wireless Local Area Network (WLAN).

-Wide area network…
Wide area network, or WAN. In terms of purpose, many networks can be considered general purpose, which means they are used for everything from sending files etc.

-Metropolitan area network…
MAN or Metropolitan area Network covers a larger area than that of a LAN and smaller area as compared to WAN. It connects two or more computers that are apart.

-Wireless LAN…
WLAN (Wireless Local Area Network) helps you to link single or multiple devices using wireless communication within a limited area like home, school, or office

-Wireless network…
A Wireless Local Area Network or WLAN is a network that is used to connect different devices without using wires etc.

-Storage area network…
Storage Area Network is a type of network which allows consolidated, block-level data storage. It is mainly used to make storage last longer etc.

-Personal area network…
PAN can be used for establishing communication among these personal devices for connecting to a digital network and the internet.

-Campus area network…
A Metropolitan Area Network or MAN is consisting of a computer network across an entire city, college campus, or a small region. This type of network is large.

Explain your own understand about protocol and standards

A protocol defines a set of rules used by two or more parties to interact between themselves. A standard is a formalized protocol accepted by most of the parties that implement it.

explain layers in OSI model

Physical, Data Link, Network, Transport, Session, Presentation, and Application.

Explain layers in tcp/ip model

Four layers of TCP/IP model are 1) Application Layer 2) Transport Layer 3) Internet Layer 4) Network Interface. ... It is also known as a network layer. Transport layer builds on the network layer in order to provide data transport from a process on a source system machine to a process on a destination system.

what are the peer to peer processing

In peer-to-peer (P2P) networking, a group of computers are linked together with equal permissions and responsibilities for processing data. Unlike traditional client-server networking, no devices in a P2P network are designated solely to serve or to receive data

8.11 LAB: Count characters - functions Write a program whose input is a character and a string, and whose output indicates the n

Shkiper50 [21]

Answer:

#include<iostream>

using namespace std;

int CountCharacters(char userChar, const string inputstr){

int k = 0;

int iter = 0;

for (iter = 0; iter < inputstr.size(); iter++){

if (inputstr[iter] == userChar){

++k; }}

return k;}

int main(){

string str;

char userChar[1];

cout<<"Char: "; cin>>userChar;

cin.ignore();

cout<<"String: "; getline(cin, str);

cout<<CountCharacters(userChar[0],str);

return 0;}

Explanation:

Written in C++:

The function is defined here:

int CountCharacters(char userChar, const string inputstr){

This initializes a count variable k to 0

int k = 0;

This initializes an iterating variable iter to 0

int iter = 0;

This iterates through the characters of the string being passed to the function

for (iter = 0; iter < inputstr.size(); iter++){

This checks for matching characters

if (inputstr[iter] == userChar){

If found, k is incremented by 1

++k; }}

This returns the total count

return k;}

The main begins here

int main(){

This declares a string variable

string str;

This declares a character variable

char userChar[1];

This gets input for the character variable

cout<<"Char: "; cin>>userChar;

This lets the user get another input

cin.ignore();

This gets input for the string variable

cout<<"String: "; getline(cin, str);

This calls the function and return the count of character in the string

cout<<CountCharacters(userChar[0],str);

Which orientation style has more height than width?

gayaneshka [121]

Answer:

"Portrait orientation" would be the correct answer.

Explanation:

The vertical picture, communication as well as gadget architecture would be considered as Portrait orientation. A webpage featuring portrait orientation seems to be usually larger than large containing lettering, memo abases as well as numerous types of content publications.
One such volume fraction also becomes perfect for impressionism depicting an individual from either the top.

Thus the above is the correct answer.

which feature will configuring a SOHO network in which all ports on the public untrusted network will be forwarded to one workst

Ugo [173]

Answer:

Demilitarized zone (DMZ).

Explanation:

Demilitarized zone is a kind of security assurance scheme used by network administrator to detect network breach even before it gets to the secured network.

The private LAN is protected with a firewall and a DMZ is configured to allow access by untrusted users, on another workstation, which is a duplicate of the companies private local address.
