Current and Future issues in Operating system
Abstract
Last few decades the use of computer system has been rapidly increased in our lives because of tremendous use in different fields and provide an outstanding way to solve problems. The major reason why computer systems are important parts and successful because of stunning use of graphical Operating systems that are running on such machines. Advancement in computer systems design and the trend to multiple processors manufacturing is becoming more and more powerful for that purpose it is also important to maintain operating systems updated for efficiently and smarter use of hardware components. This paper highlights the current and future issues in operating system, currently computer users

The first computer was created for calculations only but in these days advancement in computer technology has made us fully confident in solving different types of problems within less amount of time. The program (OS) that is running on that machine has played an important role in computer technology. The use of an Operating system is everywhere, it is a master program that is responsible for allocating resources and control execution of process. In these days computers are not called by the name of manufacturers but they are called to be Mac PC or window PC etc. Therefore, changes in programs (Operating systems) have great effects for computer users. Last changes in operating systems like the giant rise from command-line interface to current graphical user interface that made many common tasks easier for the computer users. However, the progress in operating systems is becoming more and more dynamic and classy but still there is remains a lot of work to make them fully confident to take full functionalities of advance computer hardware. In this paper we will highlight some of the key issues that operating system faces and that remain in the world of operating systems as an unconquered challenge. First, in related works we will focus on smart card operating systems and after that we will focus on current issues in operating systems such as security, memory management …show more content…
In this section of paper, we will focus on smart card operating system such as CAMILLE. It is designed by the University of Lille [2] and Gemplus Research Labs for smart cards devices. The basic purpose of CAMMILE is to support different types of resources used in smart card devices. The basic architecture of CAMMILLE is very close to MIT Exo-Kernel principles and concepts [3]. CAMMILE has four different types of properties for applications such as security, interoperability, portability and extensibility [4]. Embedded code is represented in language called FAC, ADE [5] and source code can be written in widespread languages. CAMMILE shows simple representation of hardware
In CRC, a sequence of redundant bits, called cyclic redundancy check bits, are appended to the end of data unit so that the resulting data unit becomes exactly divisible by a second, predetermined binary number. Error correction code (ECC) techniques have been widely used to correct transient errors and improve the reliability of memories.here we were tried for FFT. Figure 7:synthesis diagram of SOS based ECC for FFT. The figure 7 is desinged by using verilog language with xilinix synthesis tool.for this design we had to use 4 to 8 bit Fault FFT with ECC Concept. The ECC codes utilize the less area than previous module.
This polymorphic instance generates Fibonacci pseudonoise (PN) bit sequences. The selected pattern is repeated until the user-specified number of total bits is generated. Use this instance to specify a PN sequence order based on which the VI selects a primitive polynomial that returns an m-sequence. Use this instance to specify the primitive polynomial that determines the connection structure of the linear feedback shift register (LFSR). total bits specifies the total number of pseudorandom bits to be generated.

It also support bit locker drive encryption, which encrypt window hard disk to keep documents and passwords as well. Also help to protect desktop against viruses and other malware with Microsoft security essential. It also supports parent’s control which is also an essential part.
Each configuration has its advantages and disadvantages; complexity or flexibility, cost (hardware and software), performance, scalability and user load. We have software that is designated with a site license, meaning that we can run unlimited instances at our physical address. We have other software packages that are licensed to an individual user’s device. Multiple variables must be considered in deciding how software is loaded and presented to the user base. Each software package has it individual licensing and system requirements.
In this modern world the need for designing and developing an application with good secure features is very high. I have also learned what an error exceptional handling is and why is it important in code review. I have also learned that in developing a software product or in the software development life cycle process, a software product must be teste in earlier stages and very frequently. This recalled my knowledge of secure software development life cycle. One must know the importance of secure software development life cycle.
Unit 2 – P3 and D1 Intro: Throughout this assignment, I will be discussing about how to manage and maintain an operating system for e.g. removing files that may contain viruses and cleaning files that are unnecessary in the operating system. I will also be talking about the benefits and drawbacks of each software utilities and I will be explaining and defining what each of the definitions actually mean. There are four essential categories that I will be focusing on and this will be explained later on. Security
Brief Summary of the lecture contents, lab activity, group discussion and reading materials Week five, we continue learning key components of web programming, and this week we are going to be trained in two of the most sensitive and important practices on internet nowadays; online payments and security practices. We will be installing, configuring and operating eComerce applications, really important especially if you wan to be a good programmer and/or system administrator. After reading the material provided and becoming familiar with the topics we had to use this model to create some server script.
Following is a report completed for the executives of Frist World Bank Savings and Loan, with the objective to provide information on appropriate kernel options including the pros and cons of each. The importance of a software management plan, the use of installing anti-virus software on our Linus servers, monitoring and logging techniques used in a typical Linux infrastructure are all included within. Additionally, a description and explanation of the importance of a suitable backup plan is described. First let’s discuss each option and understand each. The kernel is highly configurable, it represents an opportunity to better secure our systems.
If there are so many programs, and the resources are limited, this software called (kernel) also decides when and how long a program should run. It is also called scheduling. It might be very complex to access the hardware directly, since there’re so many different hardware designs for the same type of components. Usually kernels implement somehow level of hardware abstraction to hide the underlying complexity from applications and provide a uniform interface. This also helps application developers to develop

Technology and Its Control Over Society In many of his pieces, writings, and novels, Ray Bradbury reflects the immense reliance and close connection that humanity has with technology. He also depicts the dangerous effects that could come from having this relationship, such as a loss of independency and self-control over one’s mind and actions. If humanity were to continue to allow technology to have this disastrous power and control, society’s downfall is certain and destined to come.
Quantum Computing: A Leap Forward in Processing Power We live in the information age, defined by the computers and technology that reign over modern society. Computer technology progresses rapidly every year, enabling modern day computers to process data using smaller and faster components than ever before. However, we are quickly approaching the limits of traditional computing technology. Typical computers process data with transistors.1 Transistors act as tiny switches in one of two definite states: ON or OFF.
Future… it always seems so far away from me. As a younger generation of this complex world, I used to not think that I am part of this community to make the world a better place to live in. However, as I grow to become more matured, I will ask myself sometimes, what can we as the younger generation do to contribute to this community. Can we really go beyond the standards set for us by the pioneers?
