Introduction to Computer System-ppt.pptx
A computer is an electronic device that can process and store data. It is made up of various hardware components, such as a central processing unit (CPU), memory, storage devices, input/output devices, and communication interfaces.
The CPU is the brain of the computer and performs most of the processing tasks. It retrieves data from memory, performs calculations, and executes instructions. Memory, also known as RAM (Random Access Memory), is used to store data and instructions temporarily while they are being processed by the CPU.
cental processing unit and all its components
A computer system consists of interconnected hardware and software components that work together to perform tasks. The document outlines the key components of a computer system, including input devices, processing units like the CPU and memory, and output devices. It describes the functions of a computer system like input, processing, output and storage. It also discusses different types of computer systems and provides an overview of the information processing cycle that computers use to receive, process and output data.
History, classification and components of computers
A computer is a programmable machine that receives input, stores and manipulates data, and provides output. It has several core components: a central processing unit that executes instructions, memory to store data and programs, input and output devices to enter and display information, and mass storage to permanently save large amounts of data. Computers can be classified based on their size and function, ranging from personal computers for individual use to servers that provide network services to embedded computers inside devices to supercomputers for intensive data processing.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Recycled Concrete Aggregate in Construction Part III
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

- 3. 1) super computer – the fastest, largest , most powerful and most expensive computer 2) main frame computer – this is a little smaller and less powerful than the super computer, but ,like the super computer it is also expensive 3)personal computer – this is the computer that most people use in their daily lives. This computer is much smaller , less powerful and less expensive than the super computer and the main frame computer .
- 4. Input : information and programs are entered into the computer through input devices such as the keyboards , disks, or through other computers via network connections or modems connected to the internet. The input device also retrieves information off disks. output : output devices displays information on the screen (monitor) or the printer and sends information to the computer . they also display messages about what errors may have occurred and brings up message or dialog box asking for more information to be input . The output devices also saves information on the disk for future use . Processing : The CPU or central processing unit is sometimes called the control unit and directs the operation of input and out devices . The co processor or arithmetic logic unit does arithmetic and comparisons . The memory or RAM temporarily stores informations( files and programs) while you are using or working on RAM.
- 5. Hardware : Physical components that make up a computer system . Software : Computer programs and related datavthat provide the instructions for telling computer hardware what to do and how to do it .
