Available in PDF, EPUB and Kindle. Book excerpt: A good understanding of storage devices and file systems helps investigators locate information during the investigation process. A forensic investigator must have knowledge of the structure and functioning of storage devices used in various computing devices. In the book "Understanding Hard Disks and File Systems," you will learn about storage devices such as hard disk drives and SSDs. You will understand more about the components and characteristics of disk drives in a better way. Further, we will understand the logical structure of these storage devices and the distribution of data on the disk. Computer hardware is nothing without the operating system and software. In the next chapter of this book, we will learn about how different operating system works. We will understand the booting process of Windows, Linux, and Mac operating systems in a concise manner. we will look into file systems in these operating systems. Furthermore, we will examine file systems using forensics tools such as Autopsy and the sleuth kit. As storage technology is advancing, we have got various new technology to store our digital data. Redundant Array of Independent Disks (RAID) and Network-Attached Storage (NAS) are helping organizations and individuals store their information in an efficient way. Hence, we will also go through NAS and RAID storage systems. There we will learn more about the architecture and working of these storage systems. In Digital Forensics Investigations, investigators in search of the remnants of deleted files, use Hex Editors which shows the physical contents of the disk including the files, folders, and partitions. So we will spend some of our time learning character encoding and hexadecimal notation. Further, at the end of this book, we will learn to analyze PDF, JPEG, and other document formats using Hex editors to find any malicious segment embedded in them.

Download or read book Understanding the Linux Kernel written by Daniel Pierre Bovet and published by "O'Reilly Media, Inc.". This book was released on 2002 with total page 786 pages. Available in PDF, EPUB and Kindle. Book excerpt: To thoroughly understand what makes Linux tick and why it's so efficient, you need to delve deep into the heart of the operating system--into the Linux kernel itself. The kernel is Linux--in the case of the Linux operating system, it's the only bit of software to which the term "Linux" applies. The kernel handles all the requests or completed I/O operations and determines which programs will share its processing time, and in what order. Responsible for the sophisticated memory management of the whole system, the Linux kernel is the force behind the legendary Linux efficiency. The new edition of Understanding the Linux Kernel takes you on a guided tour through the most significant data structures, many algorithms, and programming tricks used in the kernel. Probing beyond the superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Relevant segments of code are dissected and discussed line by line. The book covers more than just the functioning of the code, it explains the theoretical underpinnings for why Linux does things the way it does. The new edition of the book has been updated to cover version 2.4 of the kernel, which is quite different from version 2.2: the virtual memory system is entirely new, support for multiprocessor systems is improved, and whole new classes of hardware devices have been added. The authors explore each new feature in detail. Other topics in the book include: Memory management including file buffering, process swapping, and Direct memory Access (DMA) The Virtual Filesystem and the Second Extended Filesystem Process creation and scheduling Signals, interrupts, and the essential interfaces to device drivers Timing Synchronization in the kernel Interprocess Communication (IPC) Program execution Understanding the Linux Kernel, Second Edition will acquaint you with all the inner workings of Linux, but is more than just an academic exercise. You'll learn what conditions bring out Linux's best performance, and you'll see how it meets the challenge of providing good system response during process scheduling, file access, and memory management in a wide variety of environments. If knowledge is power, then this book will help you make the most of your Linux system.

Book excerpt: A Primer for Computational Biology aims to provide life scientists and students the skills necessary for research in a data-rich world. The text covers accessing and using remote servers via the command-line, writing programs and pipelines for data analysis, and provides useful vocabulary for interdisciplinary work. The book is broken into three parts: Introduction to Unix/Linux: The command-line is the "natural environment" of scientific computing, and this part covers a wide range of topics, including logging in, working with files and directories, installing programs and writing scripts, and the powerful "pipe" operator for file and data manipulation. Programming in Python: Python is both a premier language for learning and a common choice in scientific software development. This part covers the basic concepts in programming (data types, if-statements and loops, functions) via examples of DNA-sequence analysis. This part also covers more complex subjects in software development such as objects and classes, modules, and APIs. Programming in R: The R language specializes in statistical data analysis, and is also quite useful for visualizing large datasets. This third part covers the basics of R as a programming language (data types, if-statements, functions, loops and when to use them) as well as techniques for large-scale, multi-test analyses. Other topics include S3 classes and data visualization with ggplot2.

Download or read book ExFAT and FAT File Systems Internals written by Dr Keshava Munegowda and published by . This book was released on 2021-05-06 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main focus of this book is to introduce the internals of ExFAT File system to the reader and also to compare with the internals of the TexFAT File system in depth. But, as a prerequisite to cover the essential file system details, this Book starts with introduction of the internals of FAT series file systems such as FAT 12, FAT16 and FAT32. These FAT series file systems are compared with each other in terms of features and limitations and then this book covers the internal details of the ExFAT File system and its differentiating features with respect to the FAT32 File system. The Transactional features of TFAT and TexFAT File systems are also discussed in detail. This book also discusses how to optimize the FAT and ExFAT File systems for SSDs (Solid State Drives). The data structures used to represent files/directories and the algorithms used to manage file system operations of FAT series file systems, ExFAT, TFAT and TexFAT File systems are explained in detail. The snapshots of on-disk structures of files, directories and data of the files/directories are also given along with explanations so that readers will get the feel of exact internals of how the files/directories are represented and how the on-disk updates are performed by the file system operations. Even though the FAT file system is available since the HDDs (Hard Disk Drives) era and the specification of FAT File system is available, But, in this book, the reader may find the FAT file system explanation with respect to SSDs. The example scenarios of the FAT File system data corruptions are also demonstrated. The on-disk layout snapshots of FAT and other file systems help the reader to understand the file systems internals easily.This book is written with the assumption that the reader need not have any file system knowledge as a prerequisite. Intended audience for this book are computer and information science beginners / students, computer and Information technology (IT) professionals working on file systems of HDD / SSDs / Flash memories and the professionals who are interested in doing forensic analysis on-disk file system patterns on storage devices.
