An equality comparator is a hardware electronic circuit made from logic gates that takes two binary numbers as input determines whether these are equal or not. Equality comparators and magnitude comparators (used to determine whether a binary input is larger,…
Calculating the square value of a number is a very straightforward process which consists of multiplying this number by itself. For instance: 152 = 15 x 15 = 225 The reverse operation which consists of calculating the square root of…
In this blog post, we will write a computer program to create and maintain a multimedia library of books, CDs and DVDs. The aim of this programming task is to demonstrate some key Object-Oriented Programming concepts such as: Creating Classes…
The aim of this challenge is to implement a Class in Python to maintain an MP3 Playlist. This class could be used when developing the software for a music App on a smartphone or an mp3 player. This MP3 playlist…
One of the key features of any e-commerce website is the shopping basket. It is used to let the end-users add products to their basket before proceeding to checkout. In this Python challenge we will create a Shopping Basket class…
In this blog post we will experiment using some of the key functions from the random library. Many Python games will involve some degree of “randomness” for the game to be more realistic and unpredictable. Flipping a coin, throwing a…
In the 1980’s, when IBM introduced the IBM PC which was built with the Intel 8088 microprocessor, they needed an operating system. They approached Microsoft who provided IBM with the “Microsoft Disk Operating System”: MS-DOS. A Disk Operating System is…
In this blog post we will design an electronic circuit using logics gates (combined into D-Type flip-flop circuits) to create a 4-bit binary counter. This approach will help us understand how a program counter may be designed within the CPU…
In the middle of last winter, eight guests were invited to a luxurious retreat at the Duke of York Grand Hotel. On the last day of their three-day getaway, the guests were free to vacate to their own occupations. Mrs…
In this blog post we will investigate how to create some basic classes and objects that could be used in a range of programming projects. Classes and Objects are the building blocks of Object-Oriented programs. You can find out about…
