It provides details on the structure and operation of these different memory and storage technologies.
Secondary Storage Devices
Secondary Storage DevicesWe Learn - A Continuous Learning Forum from Welingkar's Distance Learning Program.
Secondary storage devices are used to store data semi-permanently as primary storage is volatile. Common secondary devices include floppy disks, hard disks, CDs/DVDs, pen drives, and magnetic tapes. Floppy disks use magnetic material coated plastic disks to store data in tracks and sectors, allowing direct access. Hard disks have multiple rigid platters that spin rapidly, containing data on both sides. Data is read and written by heads positioned very close to surfaces. Pen drives use flash memory and a USB interface for portable storage. DVDs can store more data than CDs due to higher density encoding and multilayer capabilities.Working of Volatile and Non-Volatile memory
Secondary storage devices such as hard disks, optical discs, and solid-state storage are used to permanently store programs and data on a computer system. Hard disks use rigid materials and can hold greater amounts of data than floppy disks. Optical discs such as CDs, DVDs, and Blu-ray discs are commonly used for multimedia and installing applications. Various file allocation methods such as linked lists are used to organize files on these secondary storage devices. Encoding schemes like RLL and ZBR are used to efficiently store data by increasing density. Networking protocols and models like TCP/IP and OSI provide communication standards between storage devices, computers, and across networks.
DIRECT ACCESS STORAGE DEVICES
Direct access storage devices (DASDs) include magnetic disks, optical storage devices, and flash memory. Magnetic disks can be fixed-head or movable-head. Movable-head disks use a disk pack of stacked platters and read/write heads that move together to access data located in cylinders. Optical storage uses lasers to read microscopic pits on disks like CDs, DVDs, and Blu-ray discs, allowing more data storage than magnetic disks. Flash memory uses transistors to store data in blocks that must be erased before being rewritten.

Hardware
The document discusses various hardware components of a computer system including:
1. The central processing unit (CPU) which executes programs and manages other hardware. Multi-core processors have multiple processors to work on different programs faster than a single core.
2. Memory comes in different types for different purposes such as RAM for temporary storage and ROM to start the machine. Secondary storage like hard drives provide larger but slower storage.
3. Input devices such as keyboards, mice, and touchscreens allow input into the system. Output devices like monitors, printers, and speakers allow the system to produce output.
Intro computers
Computer systems have four main parts - hardware, software, data, and users. Hardware includes physical components like processors and memory, while software provides instructions. Data is stored information, and users interact with the system. Computers use processors to manipulate data according to program instructions stored temporarily in primary memory like RAM, and more permanently in secondary storage like hard disks. Memory hierarchies allow for faster access to smaller amounts of frequently used data in components like cache. Optical disks provide large but read-only secondary storage, while magnetic disks allow for rewriting and portability.
Computer memory
Computer memory comes in a memory hierarchy from fastest and smallest to slower and larger. At the top are CPU registers for temporary storage, followed by cache memory for faster access. Main memory (RAM) is volatile storage inside the computer. Secondary storage devices like hard disks and optical disks provide non-volatile storage of large amounts of data. Memory and storage technologies use electrical charges, magnetic fields, or pits and lands on optical media to store binary data representing 0s and 1s.
Week4 final
This document discusses different types of storage devices and how they function, including their relative speeds, capacities, and uses. It begins by explaining the hierarchy of storage devices from fastest to slowest: registers, cache, RAM, hard disks, optical disks, magnetic tapes, and solid state storage. The document then covers specific storage technologies like hard disk drives, optical disks (CDs, DVDs, Blu-ray), magnetic tapes, solid state drives, smart cards, and flash memory. It compares their performance and how operating systems manage storage using techniques like formatting, file systems, defragmentation, and compression.
memory unit
This document discusses computer memory and storage devices. It describes the main types of memory, including RAM, ROM, PROM, and EPROM. It also outlines various storage devices such as magnetic disks, optical disks, hard disks, floppy disks, CDs, DVDs, and Blu-ray discs.

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Medical image analysis has witnessed significant advancements with deep learning techniques. In the domain of brain tumor segmentation, the ability to
precisely delineate tumor boundaries from magnetic resonance imaging (MRI)
scans holds profound implications for diagnosis. This study presents an ensemble convolutional neural network (CNN) with transfer learning, integrating
the state-of-the-art Deeplabv3+ architecture with the ResNet18 backbone. The
model is rigorously trained and evaluated, exhibiting remarkable performance
metrics, including an impressive global accuracy of 99.286%, a high-class accuracy of 82.191%, a mean intersection over union (IoU) of 79.900%, a weighted
IoU of 98.620%, and a Boundary F1 (BF) score of 83.303%. Notably, a detailed comparative analysis with existing methods showcases the superiority of
our proposed model. These findings underscore the model’s competence in precise brain tumor localization, underscoring its potential to revolutionize medical
image analysis and enhance healthcare outcomes. This research paves the way
for future exploration and optimization of advanced CNN models in medical
imaging, emphasizing addressing false positives and resource efficiency.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

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.
