Four Functions Of A Computer
This presentation describes the four basic functions of computers and identifies hardware components that specialize in each of the four functions.
Fundamental elements of computer
The core of a computer system is the system unit, which houses key components like the motherboard, disk drives, and power supply. The system unit comes in different case types like desktop and tower cases. The most important component inside is the motherboard, which connects all other components like the CPU. The CPU or central processing unit interprets and executes instructions and is the computer's brain. Main memory, like RAM, interacts directly with the CPU millions of times per second to hold active programs and data. Secondary memory, like hard disks, floppy disks, and CDs, is used for long-term storage. Other components include video cards for display, modems for internet connectivity, power supplies, and cables connecting internal
Difference between hardware and software computer hardware vs software
This document discusses the difference between computer hardware and software. Computer hardware refers to the physical devices that can be seen and touched, such as a monitor, keyboard, mouse, and storage devices. Computer software refers to sets of instructions and code that tell the computer hardware how to perform tasks; software cannot usually be seen or touched. Some key differences are that hardware can fail over time due to wear, while software failures tend to be due to bugs and can be fixed; hardware is physical while software is logical; and hardware is used to run software programs.
Basics of Computer
A computer is a machine that allows users to enter data, process information, and produce output like documents, pictures, and music. It uses hardware components that can be touched like a CPU, monitor, keyboard, and mouse, as well as software programs and operating systems to perform tasks. The document then explains the basic parts and functions of a computer system including inputs, processors, memory, outputs, file management, desktop interface, start menu, and booting process.
Informationprocessingcycle 120516065809-phpapp01
The document discusses the information processing cycle which includes four main steps: (1) input - entering data using devices like keyboards, mice, and scanners; (2) processing - the CPU performs operations on the data; (3) storage - data and programs are stored on storage devices like hard drives; (4) output - processed data is output using devices like monitors, printers, and speakers. The document provides examples of input, storage, and output devices and explains their functions within the information processing cycle.
Semantical Cognitive Scheduling
This document discusses semantical cognitive scheduling, which aims to improve process scheduling by considering the current state of the operating system. It proposes assigning a utility value to each process-state pair based on the semantical progress gained from running that process in that state. This allows the scheduler to maximize total utility by considering the current system state. Obtaining utility values can be done through machine learning, user feedback, or from software vendors. While the general problem of finding the optimal scheduling order is hard, complexity can be reduced by assuming the number of states is bounded. Dynamic programming and greedy approaches are proposed to find high-utility schedules in polynomial time by exploiting this bounded state space assumption.

Abstract The ABM methodology is a favorable approach to model and analyze complex social phenomena that may involve non-linear feedback loops. It has been applied successfully to model a number of social phenomena involving different social processes and organizational structures. Availability of cheap computing power and rich software resources has made ABM a widely used and hence more popular methodology. A modeler using ABM however have be careful about choosing the right amount of detail (less and more both can be problematic) and validating (internal and external) the model. Interpreting and analyzing results is also an involved task. In this paper, we have demonstrated how ABM can be applied to model and analyze the voting preference formation and resultant voting decisions of individuals in a population. The model assumes a two party system. We designed three versions of the simulation and observed the results for a large number of runs with different parameter variations. The results obtained present interesting picture and resultant inferences.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
