E-commerce, the online buying and selling of goods and services, has significantly impacted trade, employment, and unemployment. This research essay provides a comprehensive analysis of its effects.

Contrary to popular belief, e-commerce has led to the growth and expansion of trade by breaking down geographical barriers and providing access to global markets for businesses, particularly SMEs. It has also created job opportunities in areas such as operations, logistics, customer service, web development, and digital marketing.

While certain sectors have experienced disruption, traditional businesses can adapt and benefit from e-commerce by adopting omni-channel strategies. The retail industry, in particular, has undergone significant transformation. E-commerce has empowered small businesses, allowing them to compete with larger enterprises and fostered entrepreneurial growth and innovation. However, there have been job displacements in some areas, necessitating individuals to transition and acquire new skills.

Introduction to Computer

Computers are the machines that can perform tasks or calculations according to set of instructions or programs. The term computer is derived from the word compute which means to calculate. Computer is an electronic device that can perform arithmetic and logical calculations faster. The first fully electronic computers, introduced in 1940s, were huge machines that required teams of people to operate. Compared to those early machines, today's computers are not only thousand times faster, they can fit on your desk, lap and even pocket. You must appreciate the impact of computer in our day-to-day life. The computer has been useful in reservation of tickets in Airlines and Railways, payment of telephone and electricity bills, deposits etc.

Advantages of computer

Computers are very fast due to which thousands of job can be performed within a short period of time.

Complex mathematical problems and logical operations can be solved by using this computer.

As computer is a versatile device, multiple task like communication, graphics, documentation can be done.

A huge amount of data can be stored and retrieved as it has high storage capacity.

Disadvantages of computer

Computers are machine hence, they have no brain so they work according to the program instructions set inside it.

It is an electronic device and it uses electrical sources to work, so it is very risky to store data and information on the computer independently because some electrical and electronic damages may damage the data. So we have to make regular backup of the data.

Since computers are very expensive device, it becomes beyond the capacity of general user. But now a day its price is going down than past.

Computers require dustless and temperature maintained environment for best performance

The phrase simply implies that computer can be used for communication and information in schools.

It should be noted that a computer is an electronic machine that can be used to make one's work easier and faster.

With respect to teaching and learning, the phrase implies that computer is vital in schools. It can be used to enhance learning.

case 1:

letter_grade = 'D';

break;

case 2:

letter_grade = 'C';

break;

case 3:

letter_grade = 'B';

break;

case 4:

letter_grade = 'A';

default:

std::cout << "Invalid GPA." << std::endl;

return 0;

}

std::cout << "Your GPA is " << gpa << ", your letter grade is " << letter_grade << std::endl;

Answer:

The primary difference between WPA2-Personal and WPA2-Enterprise is in how the authentication process is handled.

WPA2-Personal uses a pre-shared key (PSK) method for authentication, where all users share the same password. This method is suitable for small home networks where there are a limited number of users.

On the other hand, WPA2-Enterprise uses a more complex method of authentication, such as the Extensible Authentication Protocol (EAP), to authenticate each individual user on the network. This method is more suitable for larger organizations with many users, as it provides greater security and control over network access. Additionally, WPA2-Enterprise requires the use of an authentication server, such as a RADIUS server, to manage user authentication.

The total number of AC cycles completed in one second is referred to as the current's frequency. Therefore, the correct answer is frequency. (option c)

Define AC current: Explain that AC (alternating current) is a type of electrical current in which the direction of the electric charge periodically changes, oscillating back and forth.

Understand cycles: Describe that a cycle represents one complete oscillation of the AC waveform, starting from zero, reaching a positive peak, returning to zero, and then reaching a negative peak.

Introduce frequency: Define frequency as the measurement of how often a cycle is completed in a given time period, specifically, the number of cycles completed in one second.

Unit of measurement: Explain that the unit of measurement for frequency is hertz (Hz), named after Heinrich Hertz, a German physicist. One hertz represents one cycle per second.

Relate frequency to AC current: Clarify that the total number of AC cycles completed in one second is directly related to the frequency of the AC current.

Importance of frequency: Discuss the significance of frequency in electrical engineering and power systems. Mention that it affects the behavior of electrical devices, the design of power transmission systems, and the synchronization of different AC sources.

Frequency measurement: Explain that specialized instruments like frequency meters or digital multimeters with frequency measurement capabilities are used to accurately measure the frequency of an AC current.

Emphasize the correct answer: Reiterate that the current's frequency represents the total number of AC cycles completed in one second and is the appropriate choice from the given options.

By understanding the relationship between AC cycles and frequency, we can recognize that the total number of AC cycles completed in one second is referred to as the current's frequency. This knowledge is crucial for various aspects of electrical engineering and power systems. Therefore, the correct answer is frequency. (option c)

Explanation:

The sum of their ages is √961 = 31

If Joe is x years old, the equation that follows is:

x + (x+5) + (x+5+6) = 31

This simplifies to

3x = 31 - 11 - 5 = 15

so x=5

From that you can find

Joe = x = 5

Kate = x+5 = 10

Jody = x+5+6 = 16

The program illustrates the use of conditional statements. Conditional statements in programming are statements that may or may not be executed. Their execution depends on the truth value of the condition.

The program in Python, where comments are used to explain each line is as follows

#This gets input from the user

#This checks if user input is GR_APPLES or GR_BANANAS

if(userItem == "GR_APPLES" or userItem == "GR_BANANAS"):

#If yes, the program prints Fruit
