Answer and Explanation:
In coding, an expression is used to represent values. It may contain variables and/or constant.
Examples of expressions are:
[tex]a - b[/tex] [tex]a * 2[/tex] [tex]4 - 3[/tex]
Variables are literally memory locations. They are used to storing values, and they assume the values they store during program execution.
At any point in the program, the value of the variable can be changed.
Lastly, there are guidelines that follow naming variables (depending on the programming language).
Examples of accepted variable names (in C++) are:
num, num_1, num1
Assignment operator
This is the = sign. It is used for assigning values to variables.
Examples of how it is used are:
[tex]num1 = a - b[/tex]
[tex]num\_1 = a*2[/tex]
[tex]num = 4 - 3[/tex]
The following is a wrong usage of the operator
[tex]4 - 3 = num[/tex]

A programmer for a weather website needs to display the proportion of days with freezing temperatures in a given month.
Their algorithm will operate on a list of temperatures for each day in the month. It must keep track of how many temperatures are below or equal to 32. Once it's done processing the list, it must display the ratio of freezing days over total days.
Which of these correctly expresses that algorithm in pseudocode?
A.
numFreezing ← 0
numDays ← 0
FOR EACH temp IN temps {
IF (temp ≤ 32) {
numFreezing ← numFreezing + 1
}
numDays ← numDays + 1
DISPLAY(numFreezing/numDays)
}
B.
numFreezing ← 0
numDays ← 0
FOR EACH temp IN temps {
IF (temp ≤ 32) {
numFreezing ← numFreezing + 1
}
numDays ← numDays + 1
}
DISPLAY(numFreezing/numDays)
C.
numFreezing ← 0
numDays ← 0
FOR EACH temp IN temps {
IF (temp < 32) {
numFreezing ← numFreezing + 1
}
numDays ← numDays + 1
}
DISPLAY(numFreezing/numDays)
D.
numFreezing ← 0
numDays ← 0
FOR EACH temp IN temps {
IF (temp ≤ 32) {
numFreezing ← numFreezing + 1
numDays ← numDays + 1
}
}
DISPLAY(numFreezing/numDays)
Answer:
B.
Explanation:
The correct Pseudocode for this scenario would be B. This code makes two variables for the number of total days (numDays) and number of freezing days (numFreezing). Then it loops through the entire data set and checks if each temp is less than or equal to 32 degrees. If it is, it adds it to numFreezing, if it is not then it skips this step, but still adds 1 to the total number of days after each loop. Once the entire loop is done it prints out the ratio, unlike answer A which prints out the ratio for every iteration of the loop.
numFreezing ← 0
numDays ← 0
FOR EACH temp IN temps {
IF (temp ≤ 32) {
numFreezing ← numFreezing + 1
}
numDays ← numDays + 1
}
DISPLAY(numFreezing/numDays)

Answer:
This is called an address bar
Explanation:
It tells your computer where to send the data and what website you are trying to communicate with.
:)
Choose the word that matches each definition. 1. IP Address 2. Server 3. Port Each term is only used once._____________ a number used within a computer to identify a specific process ____________ a numerical reference to a particular device in a network ___________ a computer that handles requests and returns data to other computers in a network
Port a number used within a computer to identify a specific process.
IP Address a numerical reference to a particular device in a network.
Server a computer that handles requests and returns data to other computers in a network.
Explanation:A port number is a number used to uniquely identify a particular process, application or program on a computer. From the networking parlance, it is a logical address that uniquely identifies a process, protocol or application communicating with other process, protocol or application over a network. For example;
i. a file transfer protocol (FTP) could use a port number of 20 or 21.
ii. a simple mail transfer protocol (SMTP) could use a port number of 25
Internet Protocol (IP) address is a numerical reference or label assigned to a particular device in a network which helps to uniquely identify the device on the network. IP addresses (version 4) are expressed as a group of four numbers separated by a dot. For example, an IP address may look like this: 192.168.0.90
A server is a computer that receives requests from other computers, processes these requests and returns some data to the other computers in a network. In reality, these servers and the computers they serve can actually be some applications or programs. Servers provide resources, data, services or programs to other computers over a network.
Answer:
IP address: an Internet Protocol (IP) address is a numerical reference to a particular device in a network
port: a number used within a computer to identify a specific process
server: a computer that handles requests and returns data to other computers in a network

Recently mobile phones have been used to pay for goods in stores and supermarkets.
One methodof payment involves holding the phone close to a reader in the store.Discuss the advantages and disadvantages of this method of payment compared with other methods of credit/debit card transactions.
Answer:
The advantages of using mobile phones to pay for goods in stores are;
1) The ability to pay for goods and/or services without having to carry a physical wallet, thereby making payments faster, more convenient, and safer as the contents of a money wallet or purse cannot be seen
2) The generation of security codes for each transactions, the use of PIN input and finger sprint scanning for payment, ensures access to payment authorization is limited and requires definitive authentication and that payment transactions will not need to be scrutinized by merchants to detect fraudulent transactions
3) Paying with the mobile phone increases privacy as the card used for payment will be known only to the person doing the payment, thereby a person can use a credit card with low limit without displaying them
The disadvantages of using mobile phones to pay for goods in stores includes;
1) The possibility of breach in security of the mobile phone during payment. Sensitive information of the mobile phone can be collected during payment and then used in other places without the permission of the owner of the phone
2) Mobile phone payment may not be suitable to people who prefer card or cash payment
3) The different mobile phone payment applications and platforms are not entirely compatible and can lead to payment challenges
