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
If you have ever used a computer, there is a good chance that you have also used a network. Companies often use networks to share resources between computers easily. There are many different types of networks. In this article, we will explore: What is a network? A network is a group of computers that you … Read more
Regardless of how good a programmer you are, you will encounter many types of programming errors in your code. Errors appear at different stages in the program implementation phase. To a novice programmer, it is important for you to be able to read and understand these error messages so that you will be able to … Read more
Programming operators are symbols that tell a compiler what mathematical or logical manipulation is to be performed on the data entered. In programming, as in mathematics, there are many operations that may be performed. However, the operators used in mathematics are not all the same as those used in programming. In this article, we will … Read more
As with any other programming language, Pascal variables are meant to hold data of different types that are expected to change while the program is being run. The types of variables used in Pascal programs are char, string, integer, real and boolean. To initialize a variable, we write the variable name followed by a colon … Read more
