Methods of memory allocation include contiguous allocation, where each file occupies contiguous disk blocks, linked allocation, where each file is stored as a linked list of disk blocks that can be scattered, and indexed allocation. Contiguous allocation allows for simple random access but is wasteful of space and does not allow files to grow, while linked allocation manages space efficiently but does not allow random access and requires mapping between blocks.

It discusses fixed and variable partitioning for static allocation, as well as first-fit, next-fit, best-fit, and worst-fit algorithms for dynamic allocation. The document also covers fragmentation, base-limit registers, swapping, paging, and segmentation for virtual memory management. The key aspects of paging include using page tables to map virtual to physical addresses, allowing sharing and abstracting physical organization. Segmentation divides memory into logical segments specified by segment tables.
file system in operating system
The document discusses different aspects of file systems and file structures. It describes files as collections of data that have long-term existence, can be shared between processes, and organized hierarchically. File systems provide storage for files and functions to manipulate them, maintaining attributes. Common file structures include sequential, indexed sequential, and direct/hashed files. The document also outlines the components of a file system software architecture and operations performed on directories.
Bus and memory transfer
This document discusses common bus systems for transferring data between registers in a computer. It explains that a bus structure uses common lines and control signals to connect one register at a time to transfer information.

File allocation methods (1)
The document discusses various file allocation methods and disk scheduling algorithms. There are three main file allocation methods - contiguous allocation, linked allocation, and indexed allocation. Contiguous allocation suffers from fragmentation but allows fast sequential access. Linked allocation does not have external fragmentation but is slower. Indexed allocation supports direct access but has higher overhead. For disk scheduling, algorithms like FCFS, SSTF, SCAN, CSCAN, and LOOK are described. SSTF provides lowest seek time while SCAN and CSCAN have higher throughput but longer wait times.
Operating system memory management
Operating System
Topic Memory Management
for Btech/Bsc (C.S)/BCA...
Memory management is the functionality of an operating system which handles or manages primary memory. Memory management keeps track of each and every memory location either it is allocated to some process or it is free. It checks how much memory is to be allocated to processes. It decides which process will get memory at what time. It tracks whenever some memory gets freed or unallocated and correspondingly it updates the status.
Virtual memory
Virtual memory allows programs to access more memory than the physical memory available on a computer by storing unused portions of memory on disk. It was first developed in 1959-1962 at the University of Manchester. Key aspects of virtual memory include: dividing memory into pages that can be swapped between disk and physical memory as needed, using page tables to map virtual to physical addresses, and page replacement algorithms like LRU to determine which pages to swap out. Virtual memory provides benefits like running more programs simultaneously but can reduce performance due to disk access times.
Disk management
This document discusses disk formatting and partitioning. It explains that low-level formatting divides a disk into sectors that can be read and written to by adding headers, data, and trailers. Logical formatting then creates a file system by adding data structures to map free and allocated space. Disks can also be used as raw disks without a file system for things like swap space. Boot blocks contain bootstrap programs to initialize the system and load the operating system from a fixed location on the boot disk. Disk controllers can manage bad blocks by marking them or replacing them with spare sectors.

Registers
Registers are small amounts of fast memory within the CPU that temporarily store data and instructions during program execution. There are different types of registers that serve specific purposes, including general purpose registers like the accumulator (AX) and base address (BX) registers, pointer registers like the base pointer (BP) and stack pointer (SP), index registers like the source (SI) and destination (DI) registers, segment registers that define memory areas for code, data and stacks, and flag registers that store status information. Registers provide fast access and storage of commonly used values to speed up CPU operations.
Os presentation
A page fault occurs when the operating system cannot find requested data in virtual memory. This can happen if the virtual memory mapping becomes corrupt. When a page fault happens, the OS must transfer the missing page from slower secondary storage to primary memory. While common with virtual memory, each fault slows processing as secondary storage access is thousands of times slower than primary memory. Installing more system RAM can reduce faults by requiring less virtual memory usage. The OS handles most faults transparently but invalid faults may crash programs unable to relocate data. Page replacement prevents over-allocation by modifying the fault routine to include swapping out unmodified pages to free space for new pages.
Flynns classification
Michael Flynn proposed a taxonomy in 1966 to classify computer architectures based on the number of instruction streams and data streams. The four classifications are: SISD (single instruction, single data stream), SIMD (single instruction, multiple data streams), MISD (multiple instructions, single data stream), and MIMD (multiple instructions, multiple data streams). SISD corresponds to the traditional von Neumann architecture, SIMD is used for array processing, MIMD describes most modern parallel computers, and MISD has never been implemented.

Chapter 12 discusses mass storage systems and their role in operating systems. It describes the physical structure of disks and tapes and how they are accessed. Disks are organized into logical blocks that are mapped to physical sectors. Disks connect to computers via I/O buses and controllers. RAID systems improve reliability through redundancy across multiple disks. Operating systems provide services for disk scheduling, management, and swap space. Tertiary storage uses tape drives and removable disks to archive less frequently used data in large installations.

Parallel processing
Parallel computing is a type of computation in which many calculations or the execution of processes are carried out simultaneously. Large problems can often be divided into smaller ones, which can then be solved at the same time. There are several different forms of parallel computing: bit-level, instruction-level, data, and task parallelism. Parallelism has been employed for many years, mainly in high-performance computing, but interest in it has grown lately due to the physical constraints preventing frequency scaling. As power consumption (and consequently heat generation) by computers has become a concern in recent years, parallel computing has become the dominant paradigm in computer architecture, mainly in the form of multi-core processors.
OS - Process Concepts
Gives an overview about Process, PCB, Process States, Process Operations, Scheduling, Schedulers, Interprocess communication, shared memory and message passing systems
Instruction codes
An instruction code consists of an operation code and operand(s) that specify the operation to perform and data to use. Operation codes are binary codes that define operations like addition, subtraction, etc. Early computers stored programs and data in separate memory sections and used a single accumulator register. Modern computers have multiple registers for temporary storage and performing operations faster than using only memory. Computer instructions encode an operation code and operand fields to specify the basic operations to perform on data stored in registers or memory.
Program Threats
This document discusses various types of program threats including logic bombs, viruses, worms, and trojan horses. It focuses on viruses, defining them as code fragments embedded in legitimate programs that can spread via email or macros. The document categorizes viruses and provides examples, noting that file viruses append to files, boot sector viruses infect boot sectors, macro viruses spread through documents, and polymorphic/encrypted viruses aim to avoid detection. In summary, it defines computer viruses, explains how they spread, and outlines several categories of viruses along with examples.
Virtual memory
The document discusses the concept of virtual memory. Virtual memory allows a program to access more memory than what is physically available in RAM by storing unused portions of the program on disk. When a program requests data that is not currently in RAM, it triggers a page fault that causes the needed page to be swapped from disk into RAM. This allows the illusion of more memory than physically available through swapping pages between RAM and disk as needed by the program during execution.
SSM
Secondary storage management involves tracking portions (groups of contiguous blocks) assigned to files using a File Allocation Table (FAT). There are two main approaches to file allocation - preallocation which requires estimating maximum file sizes up front, and dynamic allocation which allocates portions as needed. Common file allocation methods include contiguous, chained, and indexed allocation, each with advantages and disadvantages for sequential vs random access performance and fragmentation. Free space on disks is managed using techniques like bit tables, chained free portions lists, or indexes to track available blocks.
Allocation methods continuous method.47
The document discusses different allocation methods for managing disk space for files in an operating system. It describes contiguous, linked, and indexed allocation. Contiguous allocation allocates files in contiguous blocks, simplifying access but wasting space. Linked allocation uses pointers to non-contiguous blocks, avoiding fragmentation. Indexed allocation uses an index block to store block addresses, requiring multiple accesses to retrieve a block.

Allocation Methods-R.D.Sivakumar
There are three major methods for storing files on disks: contiguous, linked, and indexed allocation. Contiguous allocation stores all blocks of a file together, providing fast sequential access but risks fragmentation. Linked allocation uses pointers between blocks, avoiding fragmentation but using more space for pointers. Indexed allocation combines all file indexes into common blocks, similar to file allocation tables used in DOS that store indexes in a separate table for faster random access. The optimal method depends on file size and access patterns.
Contigious
This document discusses different file allocation methods for managing disk space, including contiguous, linked, indexed, and inode allocation. It also covers free space management techniques like bit vectors and linked lists. Inode allocation combines direct indexing, single and double indirect indexing to support very large files over 4GB by organizing file metadata and block pointers in inodes.

Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
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.

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.

memory allocation methods
- 1. METHODS OF MEMORY ALLOCATION • An allocation method refers to how disk blocks are allocated for files: • Contiguous allocation • Linked allocation • Indexed allocation
- 2. CONTIGUOUS ALLOCATIION • Each file occupies a set of contiguous blocks on the disk • Simple – only starting location (block #) and length (number of blocks) are required • Random access • Wasteful of space (dynamic storage-allocation problem) • Files cannot grow
- 3. Contiguous allocation of disk space
- 4. LINKED ALLOCATION • Each file is a linked list of disk blocks: blocks may be scattered anywhere on the disk. • Simple – need only starting address • Free-space management system – no waste of space • No random access • Mapping block = pointer
- 5. Linked allocation of disk space
