Essays on File System

An operating system forms the core of a computer in that it coordinates the processes of the computer, its memory, and all of the computer’s hardware and software. It likewise permits the user to connect with the computer even without prior knowledge of how to interpret the language of the computer. A computer without an operating system is non-functional. In most cases, there are some diverse computer programs functioning simultaneously, and they all must access the memory, storage, and the central processing unit (CPU) of the computer. The operating system harmonizes all the programs to make sure every ...

Executive Summary

The modern business environment is characterized by the increased use of information technology and data comprise an essential component of the modern information systems. Database management systems are softwares that were developed with the objective of creating, storing and retrieval of data with ease. The database management systems commonly abbreviated as (DBMS) are software systems that can easily be updated with new information with ease. They have been essential in the use of information systems because they link the end applications with the end users of a database. Additionally, unlike the traditional methods of filing where data was easily ...

Abstract

Digital forensics is a critical component of forensic discipline that includes crimes and misconducts with respect to computer systems. The use of computers to investigate online crimes led to the development of this new field known as Digital forensics. The field provides new ideas for understanding and betterment of concepts and directing future concepts in Digital Forensics. Over the last few years, with the advent of latest electronic devices such as mobile phones, tablets and laptops, the concept has gained popularity over the span of few years. This has resulted in a shift of thefts from real time to ...

Question 1

Network file system (NFS) was originally developed in 1984 by Sun microsystems. It is a distributed file system that allows a client to view, store or update file on the server remotely. It employs the open network computing remote procedure technology in implementing the desired functions. It can thus be used by anyone connected to the network to effect the changes that are desired in the network (KITAMURA, 2012). The NFS system enables the administrator to stage portions of the file system on the server. The file mounted can be accessed by the clients depending on the privileges accorded ...

Virtualization

Introduction This report aims at exploring the differences between hypervisor based and container-based virtualization technologies. In the report, the differences to be explored will touch on the implementations, the applications, the advantages and disadvantages of either technology. The report will also look at the different applications that are using the technologies.

Virtualizations: Virtualization is the practice of creation virtual resource, i.e., servers, storage devices, networks or even operating system to enable execution of applications that require a different execution environment. Virtualization is meant to increase IT agility, scalability and flexibility through faster deployment, increased performance and greater availability leading ...

Cloud Security Solutions

Private and public cloud solutions have been gaining much popularity however there are security issues that have gained a higher priority. Cloud security is a vital part of CIA (Confidentiality, Integrity, and Availability) triad for data security. The cloud functionality in itself is robust and well-paying for customers; however operational security is a concern that is being addressed by vendors. The adaptation of cloud technology has been rapid and fast paced. Cloud security issues over the cloud environment have hindered the growth of cloud industry resulting in a far lesser growth as was expected of the new technology (Donovan).

Emergence of Cloud Security Standards

Question 1: does distributed file systems eliminate need for backup

Distributed file systems are implemented over several computer servers that are located in different places enabling sharing of data across the various computer networks. The file system allows implementation of replication and access transparencies. However, the distribution process does not eliminate the need for data backup. Data backup is necessary because in distributed file systems data being shared may exist only in one computer and if lost, all other computers will not be able to access the same data (Girone, 2015). Distributed file system share data when needed by another computer, however, this does not provide for data redundancy. ...

It is estimated that the world produces over 500 million tons of paper with writing and printing papers which are mostly found in offices accounting for the largest percentage of the total paper consumption. In 2011 alone, the world saw approximately 400 million tons of paper being produced and consumed (Statista.com). Big contributors of paper consumption are the United States, China and Japan. The three countries alone account for almost half of the world’s paper production and consumption. The United States is the leading country in as far as paper export is concerned while Germany is the world’ ...
