The computer itself the hardware cannot do anything. The ingredient that enables a computer to perform a specific task is software, which consists of electronic instructions. These instructions tell the machine’s physical components what to do; without them, a computer could not do anything at all.
System Software:
The program directly related to the hardware of the computer and which perform the fundamental task are termed as system software.
Several programs may be included in system software but the following are essential for any computer.
Language Translators
A Particular translator is required to execute any high-level language program.
Each language has a different language translator, while the function of each translator is to convert the high-level program into machine code.
These translators are categorized into the following groups.
Interpreter:
These translators translate only one instruction at a time and execute it. After execution, the translation is erased from memory and the next instruction is loaded for translation. Therefore translation is required again if the program is executed again.
It is a limitation of interpreters that it forgets translation after the execution of the instruction.
A GWBASIC interpreter is required to run GWBASIC programs.
Each programming language has its separate interpreter if it is designed.
Compiler
These translators are used to translate the entire program at once and store their translated program on disk.
The original program is called “Source Program” while its translated program is called “Object Program”.
These translators can not execute an object program.
The object program has to go through some other stages to be able to execute.
Assembler
The assemblers are language translators for low-level symbolic language programs.
Assemblers can translate a source program into an object program.
An assembler translates one source instruction into exactly one machine code.
The linking process is required on the object program to be able to execute it.
Each low-level symbolic language has its assembler.

Decolonizing Universal Design for LearningFrederic Fovet
UDL has gained in popularity over the last decade both in the K-12 and the post-secondary sectors. The usefulness of UDL to create inclusive learning experiences for the full array of diverse learners has been well documented in the literature, and there is now increasing scholarship examining the process of integrating UDL strategically across organisations. One concern, however, remains under-reported and under-researched. Much of the scholarship on UDL ironically remains while and Eurocentric. Even if UDL, as a discourse, considers the decolonization of the curriculum, it is abundantly clear that the research and advocacy related to UDL originates almost exclusively from the Global North and from a Euro-Caucasian authorship. It is argued that it is high time for the way UDL has been monopolized by Global North scholars and practitioners to be challenged. Voices discussing and framing UDL, from the Global South and Indigenous communities, must be amplified and showcased in order to rectify this glaring imbalance and contradiction.
This session represents an opportunity for the author to reflect on a volume he has just finished editing entitled Decolonizing UDL and to highlight and share insights into the key innovations, promising practices, and calls for change, originating from the Global South and Indigenous Communities, that have woven the canvas of this book. The session seeks to create a space for critical dialogue, for the challenging of existing power dynamics within the UDL scholarship, and for the emergence of transformative voices from underrepresented communities. The workshop will use the UDL principles scrupulously to engage participants in diverse ways (challenging single story approaches to the narrative that surrounds UDL implementation) , as well as offer multiple means of action and expression for them to gain ownership over the key themes and concerns of the session (by encouraging a broad range of interventions, contributions, and stances).
Artificial Intelligence (AI) has revolutionized the creation of images and videos, enabling the generation of highly realistic and imaginative visual content. Utilizing advanced techniques like Generative Adversarial Networks (GANs) and neural style transfer, AI can transform simple sketches into detailed artwork or blend various styles into unique visual masterpieces. GANs, in particular, function by pitting two neural networks against each other, resulting in the production of remarkably lifelike images. AI's ability to analyze and learn from vast datasets allows it to create visuals that not only mimic human creativity but also push the boundaries of artistic expression, making it a powerful tool in digital media and entertainment industries.
