Abstract

Fault Tolerance Techniques facilitate systems to carry out tasks in the incidence of faults. A checkpoint is a local state of a process saved on stable storage. In a distributed system, since the processes in the system do not share memory; a global state of the system is defined as a combination of local states, one from each process. In case of a fault in distributed systems, checkpointing enables the execution of a program to be resumed from a previous consistent global state rather than resuming the execution from the commencement. In this way, the sum of constructive processing vanished because of the fault is appreciably reduced. In this paper, we talk about various issues related to the checkpointing for distributed systems and mobile computing environments. We also confer various types of checkpointing: coordinated checkpointing, asynchronous checkpointing, communication induced checkpointing and message logging based checkpointing. We also present a survey of some checkpointing algorithms for distributed systems.

Abstract

Privacy and security are the main concern of any social media networking sites such as Facebook, Twitter Instagram and LinkedIn etc. The primary purpose of these sites is to allow people to share interests, activities, real-life connections. Nowadays social networking sites are the main source of communication and on the other hand these sites are the peak targets for misusing the data and information. This is the fact that the maximum numbers of users are not aware about cyber threats and their lack of knowledge leads to further increase in cyber-crimes is a major challenge. Users should aware in the concerned of security and privacy during creating the account on social media, to read the instruction and follow it. There is some setting in social media platform to secure the message and share to only authorize users. Various governments and businesses are taking a variety of steps to combat cybercrime. Despite many steps, cyber security remains a major issue for many people. This paper focuses on the issues that cyber security faces in the modern era. It also covers the most up-to-date information on cyber security tactics, ethics, and trends that are transforming the face of cyber security.
