Can we distinguish between data and information? Is there a difference between these two terms? In life, these two terms are often used interchangeably. However, they are not the same. With the development of computers, data processing has become decidedly linked to information technology. In this article, we will explore the following: In business, it … Read more
Have you been wondering what a switch, router, modem, or network adapter is? These devices are fundamental parts of a computer network. Even though connecting to the internet may seem easy, it is these devices that make connectivity and communication between computing devices possible. They are used n different network topologies. In this article, we … Read more
Arrays are one of the most useful data structures used in programming. They allow us to enter and process blocks of data of the same type together. In programming, and specifically in Pascal, arrays are generally used with loops to process repetitive data, reducing the number of lines of code. In this article, we will … Read more
In this introduction, we will explore what a Mobile Network is. We will examine the technologies behind the different mobile networks (2G, 3G, 4G, and 5G). So, whether you’re a casual user or a technology enthusiast, join us as we embark on a journey to unravel the fascinating world of mobile networks. What is a … Read more
Intranet, extranet, and Internet are three distinct networking concepts that play crucial roles in connecting people and resources in today’s digital age. Each serves a different purpose and has unique characteristics. In this article, we will be looking at the following: Have you ever thought of the development the cellphone has gone through? Learn more … Read more
There are different types of wired and wireless transmission media. These are used to set up the different types of networks that exist today. Let’s embark on a journey to learn about what transmission media are, the types of transmission media, and how they have revolutionized the way we interact and exchange data in the … Read more
In this article, we explore the for and while loops in Pascal programming. Loops make our lives easier and are great tools in programming when we have many repetitive processes to run. In this article, we will explore: What are the for and while loops used for? In Pascal programming, the for and while loops allow … Read more
The case statement in Pascal is similar to the if-then-else decision-making condition in that it allows you to generate several different answers, which the user’s input will influence. It can be much simpler to implement than the if statement. In this article, we seek to make CSEC students aware of the case decision in Pascal … Read more
Control structures, conditions, or decision-making in Pascal are necessary to cater to different eventualities. These structures require the program to test and run different outcomes based on the results of those tests. In programming, decision-making is usually indicated by if-then-else or switch statements. In this lesson, we will explore two algorithms and Pascal programming examples … Read more
In recent years, wireless network technologies have replaced the older wired technologies as a way to connect computing devices. They are easier to connect to and use than their wired counterparts. They are also easier and less expensive to set up and use on the go. This makes them highly attractive to computer users on … Read more
