Question 2

Real-life problem

Premise: If an individual bought bread, then he/she went to the store
Premise: The individual bought bread
Conclusion: He/she went to the store
So, for this, the truth table will be represented as:

For the given problem, the logic problem will be represented as:

Question 3

A data transfer often talks about the movement of digital data from one place to another, from a hard drive to a USB flash drive at a specific point in time. It is commonly used for measuring how fast data is going to be transferred from one location to another. For example, ISP often provides an Internet Connection with a maximum rate of data transfer of only 1.5 Mbps. It is measured in terms of either bit per second or bytes per second. A bit is used for measuring speed, while Byte is used for measuring size (Comer, 2018).

The rate of data transfer can be tested using various online tools. Most of them are known as internet speed tests. These tools are mostly used in order to get the broadband speed promised by the Internet providers. Various speeds are measured, such as speed of downloading, uploading, and also latency. Download speed talks about the time taken to transfer a file from the Internet to the user’s home network or computer. Uploading speed is referring to as time is taken for uploading a file to the internet. At the same time, latency, also known as ping, depicts the delay in the transfer of data from a server to the user's computer.

A slow rate of data transfer is the result of the computer’s hard drive, so this can be fortunately increased. Some of the ways to enhance it are:

? Changing the file system used for formatting the drive from FAT32 to NTFS.

? Tweaking the settings of the system to perform better

? Turning off the compression of the disk

? Another method is the upgradation of USB 2.0 to USB 3.0 or new versions.

In the case of a hard drive, the data transfer rate is of two types: External rate of transfer and internal transfer rate. External is also known as curst data transfer rate or interface rate that means the speed at which the data is moving between the internal buffer and system memory. On the other hand, the internal transfer rate is also referred to as the maximum or minimum sustained rate of transfer (Bhati & Venkataram, 2017). This means the speed of data is often read and written to the hard disk. The external rate of transfer is faster than the internal just because it is purely electronic and hence not relying on the efficiency of actual physical elements.

Question 4

A set is the collection of objects. Objects in this assortment are additionally supposed to be the set components or individuals. The most important point of this is members must define it clearly and exactly. An explicit definition of the member is not able to identify the set. For example, months of the colder time of year season is indicating a set, yet a few months are not determining a set. Consequently, sets are frequently named with the assistance of capital letters (Rodionov & Zakharov, 2018). Set names are given in curly braces and separated with the help of commas. Such a representation is known as Roster or Tabular form. X= {December, January, February}

It can also be represented using a Venn Diagram.

According to the set theory, the union of two sets can be helpful to get a new set containing members of the union sets. The below example can represent this:

A= {Orange, Apple, Lemon, Avocado, Strawberry}
B= {Lemon, Avocado, Apricot, Grape}

The union will be hence depicted by A U B.

A U B= {Apple, Lemon, Avocado, Orange, Strawberry, Grapefruit, Apricot}

The Venn diagram will be hence:

In SQL Server, the UNION operator is concatenating the result sets obtained from two tables and hence eliminating the duplicated rows from the outcome. In fact, here, this is acting just like a union operator in the Set Theory. If, B and A sets are defined using SQL server’s tables then, in this context, first, create the table and then add the expressions similar to A and B.

The union of these tables will result in:

Change in the order of tables in the query will not result in any alteration.

On the other hand, the intersection of two sets is generating a set containing the common members of the intersected sets.

A∩ B = {Lemon, Avocado}

In SQL Server, the INTERSECT operator is implementing the logic of intersection in the Set Theory to tables. So, the intersection of both tables A and B can be given as:

Question 5

Hexadecimal or hex with base 16 system is mainly used for simplifying the representation of binary. This hence means that an 8-bit binary number can be written with the help of two different hex digits, one for each nibble or group of 4-bits. Hexadecimal is utilized in the following manner:

? Defining the memory location: Hex has the potential to characterize every byte as two hex digits can only be compared to eight digits at the time of using binary.

? Defining colours on the web pages: Each primary colour, such as green, blue and red, is attributed by two hex digits (Massengale, 2019). The format that is used is #RRGGBB.

? Displaying an error message: Hex is used for defining the error location in the memory. This one is hence used by the programmers to find and fix the errors.

? Representing MAC addresses: There are 12-digit hex numbers in a MAC address. The format used is either in the form MM: MM: MM: SS: SS: SS or MMMM-MMSS-SSSS. The first 6-digits of the MAC address is hence showing the adapter manufacturer's ID, while the last 6-digits represent the adapter's serial number.

Question 6

For the given scenario, it can be observed that here three inputs are present they are: employees are satisfied, management is good, and people are working hard. From the scenario, it can be said that if the management is good and employees are highly satisfied with the work environment, then automatically, the companies can foster their business. However, if the management is good, but employees are less or not satisfied, then the organization will suffer a huge loss. If all the conditions are satisfied, then, obviously, the organization will be in profit. So, the overall scenario can be presented in the truth table. Once the truth table has been created, the logic diagram can also be created easily.

So, the logic gate for this truth table would be:

In this context, the "OR" operator has been applied. It is observed that if all the inputs are false, then the output will also be false. Similarly, when two false conditions are combined with one true value, then the result will be true itself. That means that if the management is not working well and employees are not satisfied but still working with great dedication, then also the organization is gaining a huge revenue because of high productivity level. Similarly, if all three inputs are false, then the firm automatically fails to provide the best service, and there will be a huge loss in revenue.


Comprehensively, it can be said that binary and ASCII codes are mostly used for transmitting data. These are codes to transmit data often used by smaller and less-powerful computers for representing both textual data and also non-input device commands. So, the unit discussed these concepts profoundly. The unit also consisted of some descriptive parts related to the computing world. The study also depicted the use of a truth table and logic gates for inferring a premise. This also discussed the relationship between set theory and relational databases. In this direction, the researcher used UNION and INTERSECTION operation.
