Dhotre, I. (2009). Operating Systems. Technical Publications.
In his book title “Operating systems” Dhotre explains the designs and processes that determine the existence of deadlock. One of the solutions developed in this situation is to let the operator know of the existence of a deadlock and employ manual recovery methods. He continues to outline the automatic recovery methods. In general, the author has outlines two mechanisms for total recovery from deadlock. First, one or more processes are aborted to break the cycle of waiting. Secondly, the preemptive mechanism done on one or more of the deadlocked processes will release ...

This might sound to be a far-fetched theme, but in a business empire, the ultimate goal is to make a profit and remain marketable and supreme over one’s ...

Abstract

Much as mobile payments are comfortable to carry out, there is the danger of money being stolen by cyber thieves. Criminals use plenty of malware tools like Heartbleed bug or Trojan viruses to gain access to sensitive information for further manipulation. SMS interceptors allow thieves to receive the authentication text messages sent by banks on a per-lo-in principle. As far the level of safety goes, Android platforms are second safest to Apple analogues based on a walled garden App Store and a closed operating system, yet not even this product can keep mobile users safe when their inquisitiveness and desire to download ...

I have always been fascinated by computers and technology when my parents bought me a computer. I spent most of my time trying to figure out it how it operates by searching the internet for answers. At first I thought it was as simple as just clicking icons and programs, but through my newly developed interest in technology I got to understand how complex technology is. With rapid technological advancements, I learned that it was impossible to learn all the complex elements that enable computers work. However, I developed an interest in computer networks. The fact that computers can communicate ...

Introduction to the problem

The last decade has seen an increased improvement in the technology sector. At every instance, new technological advances are emerging. As technology brings in new, faster and more efficient processes, the security threats also increase, as well. For example, years back, computers were just stand-alone systems not interconnected in any way. With time, there was a need to create systems that would be interconnected through local area connection for ease of sharing information and resources. Further to the technological developments, the world became a global village whereby millions of computers are interconnected across the globe. Interestingly, as the computers shifted from, ...

Abstract

The use of encryption and decryption techniques for securing communication is as old as the art of communication. Technically, a code is used instead of data which is a signal for intent to keep data secret. In order to recover the contents from an encrypted signal, accurate decryption key is needed. The key is basically an algorithm that is used to reverse the work of the encryption technique and get original form of data. There is always a potential threat from hackers to decode encrypted signal, to avoid such issues specialized intellectuals have worked hard and defended these threats by developing more ...

Careers in the Information Communications Technology field are becoming dynamic. Many confuse the job descriptions that are found in this field.

Apple Corporation has maintained its position as Microsoft Corporation’s rival in operating system development and computer specifications offerings since its inception in the 1970s. Apple was the brainchild of Steve Wozniak, Steven Jobs and Bill Fernandez. Both Wozniak and Fernandez was already working on a personal computer, which they first built using parts from discarded piles from companies around the Santa Clara area. This first computer was named “cream soda computer”, after the drink they were consuming upon the creation of the first concept. Through Steve, Woz saw the potential of his MOS 6502 Processor and insisted Woz to ...

The Universal Serial Bus (USB) is a simple mechanism that allows plug and play abilities and supports quick, fast and easy transfer of data between removable and other hardware devices. However, the devices are also extremely effective in carrying, installing and running malware, viruses and other malicious payloads with very limited user and system interaction. They thus pose a great threat to information security as attested by a paper titled “A Survey of USB Exploit Mechanisms, Profiling Stuxnet and the possible adaptive measures that could have made it more effective” by Kevin Orrey. The attack threats from USBs include USB Dumpers, USB ...

The Top-Down Approach

Network Architecture and Design:
The Top-Down Approach

Network architecture and design are many times two separate stages in a network implementation project. McCabe (2007) identifies network architecture as a higher level concept of a network. He says that it focuses on more general relationships between the major components of a network. For example, "addressing and routing, network management, performance, and security." (p. 211). The design stage of the project normally starts after the higher level architectural plan has been approved. This is where the real detailed work starts and the nuts and bolts start to come together.
In designing your network, ...

Access control models

Access control models are the mechanisms that are used to regulate the access of users to a computer system or information systems. This paper will discuss three access models and discuss the environments in which they best operate in.

The first access model is the role based access control (RBAC). This access control model does not have a specific environment in which it operates. This is to say that it can be implemented in an operating system, application level or network level, or in database level. The privileges that are users have on the network depend on the role that the ...
