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…
The aim of this challenge is to implement a Bubble sort algorithm on a list of 10 values using LMC. We will be using our online LMC simulator to test our code online LMC simulator: Executing the Code We will…
The aim of this challenge is to write a program in LMC that will fill in the memory/RAM with the value 999, from memory location 50 onwards (up to memory location 99). Note that even though such a program may…
In computer science, self-modifying code is code that alters its own instructions while it is executing. Getting code that overwrites itself can seem dubious, rather risky and hence unrecommended. However in some cases, it is a technique that can be…
Drone displays/light shows are performed by synchronized and choreographed collections of drones that position themselves to recreate various aerial formations. Each drone is equipped with LED lights that can change colour during the display. The first drone display was presented…
Take the Quiz! (open full screen) Can you recognise the different types of cables used in IT? Do you know what are the main wireless technologies used to connect IT equipment? Take the quiz to check your knowledge of wired…
LED Dice Our aim is to create an LED Dice using a breadboard and 7 LEDs disposed as follows: We will then use three buttons/switches to control the 7 LEDs of the dice to recreate the following patterns: Octal Number…
