Answer:

First of all, people have been trading goods since civilization began. In the 1st century BC, there was the transportation of goods from China to Europe. The goods transportation took place along the Silk Road. The Silk Road route was very long in distance. This was a remarkable development in the history of Globalization. This is because, for the first time ever, goods were sold across continents.

Globalization kept on growing gradually since 1st BC. Another significant development took place in the 7th century AD. This was the time when the religion of Islam spread. Most noteworthy, Arab merchants led to a rapid expansion of international trade. By the 9th century, there was the domination of Muslim traders on international trade. Furthermore, the focus of trade at this time was spices.

True Global trade began in the Age of Discovery in the 15th century. The Eastern and Western continents were connected by European merchants. There was the discovery of America in this period. Consequently, global trade reached America from Europe.

From the 19th century, there was a domination of Great Britain all over the world. There was a rapid spread of international trade. The British developed powerful ships and trains. Consequently, the speed of transportation greatly increased. The rate of production of goods also significantly increased. Communication also got faster which was better for Global trade.

Finally, in 20th and 21st -Century Globalization took its ultimate form. Above all, the development of technology and the internet took place. This was a massive aid for Globalization. Hence, E-commerce plays a huge role in Globalization.

Convert infix to postfix

static String convertInfixToPostfix(String expression)

{

String calculation = new String("");

Stack<Character> operands = new Stack<>();

Stack<Character> operators = new Stack<>();

for (int i = 0; i<expression.length(); ++i)

{

char c = expression.charAt(i);

if (Character.isLetterOrDigit(c))

operands.push(c);

else if (c == '(')

operators.push(c);

else if (c == ')')

{

while (!operators.isEmpty() && operators.peek() != '(')

operands.push(operators.pop());

if (!operators.isEmpty() && operators.peek() != '(')

return NULL;

else

operators.pop();

}

else

{

while (!operators.isEmpty() && checkSymbol(c) <= checkSymbol(operators.peek()))

operands.push(operators.pop());

operators.push(c);

}

while (!operators.isEmpty())

operands.push(operators.pop());

while (!operands.isEmpty())

calculation+=operands.pop();

calculation=calculation.reverse();

return calculation;

}

Explanation:

Create the checkSymbol function to see what symbol is being passed to the stack.
Create the convertInfixToPostfix function that keeps track of the operands and the operators stack.
Use conditional statements to check whether the character being passed is a letter, digit, symbol or a bracket.
While the operators is not empty, keep pushing the character to the operators stack.
At last reverse and return the calculation which has all the results.

denis23 [38]

Answer:

The <u>ARPANET </u>network became functional in 1969, linking scientific and academic researchers across the United States.

Explanation:

ARPA Net is the network that has become functional in 1969 in united States. The basic purpose of this network is to link all the researchers and scientists across united states. The full form of ARPANet is Advanced Research Project Agency Network.

The importance of this network is increase because small chunks of data that are called packets has been proposed for data transmission in the network. The data is divided into small packets and send it over the network, at destination point these packets are combined together and become orignal information.

A network administrator is planning redundant devices and cabling in a switched network to support high availability. Which bene

a_sh-v [17]

Answer:

Redundant paths can be available without causing logical Layer 2 loops.

Explanation:

Spanning Tree Protocol is used to allow redundancy in the Layer 2 switched networks without creating cycles/circles also called loops.
These loops are called physical loops.
When two parts of the switched network are connected via two or more Layer 2 switches this result in a loop.
This affects the performance of the network as the result of broadcast packets flooding.
STP puts one port of the switch to forward mode and the rest of the ports within the same part of the network to the blocking mode to avoid broadcast packet flooding. STP puts all the ports that are allowing redundant paths to block mode and the one port that is left after this is placed in forward mode.
Spanning Tree Algorithm is used by STP to determine the optimal path of switch to the network.
Bridge Protocol Data Units are used to share the information about the optimal path determined by the spanning tree algorithm with other switches.
This information helps STP to eliminate the redundant paths.
So this is how STP tracks all the links in the switched network and eliminates redundant loops by allowing only one active path to the destination while blocking all other paths.

This program will store roster and rating information for a soccer team. Coaches rate players during tryouts to ensure a balance

aleksandr82 [10.1K]

Answer:

Question Options :

(1) Prompt the user to input five pairs of numbers: A player’s jersey number (0 – 99) and the player’s rating (1 – 9). Store the jersey numbers in one int array and the ratings in another int array. Output these array(i.e., output the roster).

(2) Implement a menu of options for a user to modify the roster. Each option is represented by a single character. The program initially outputs the menu, and outputs the menu after a user chooses an option. The program ends when the user chooses the option to Quit. For this step, the other options do nothing. (2 pt)

(3) Implement the “Output roster” menu option. (1 pt)

(4) Implement the “Add player” menu option. Prompt the user for a new player’s jersey number and rating. Append the values to the two arrays. (1 pt)

(5) Implement the “Delete player” menu option. Prompt the user for a player’s jersey number. Remove the player from the roster (delete the jersey number and rating). (2 pts)

(6) Implement the “Update player rating” menu option. Prompt the user for a player’s jersey number. Prompt again for a new rating for the player, and then change that player’s rating. (1 pt)

(7) Implement the “Output players above a rating” menu option. Prompt the user for a rating. Print the jersey number and rating for all players with ratings above the entered value. (2 pts)
