Computer Operating System Security Its Design And Different Aspect Of It

The Operating System manages the flow of data and tells the processor what component needs to be doing. It does this my relaying one piece of information at a time but done so fast it seems it is doing it all at the same time. It does this by giving the information to the processer in computer language, so it can understand.

Connectivity on operating systems can vary to what the user wants the system to connect to. This means that the user is able to connect the system to any device which they may require. If the user wanted to connect a printer to the Pc or Mac then they user can do that. Many devices are able to connect to the computer via a Wireless and bluetooth connection, this would save space and save the user using cables around the computer system.

Operating systems have the responsibility to ensure that users do not access the system illegally. They also perform different tasks such as managing system resources, communicate between software and hardware, monitoring performance and operate utilities and applications.

The article, which addresses security loopholes in modern computing environments, by Loscocco et al highlights what is and has been being done security wise in the past and how secure these implementations were and going forward what should be done to ensure in depth security which guarantees system wide security (1998). The article first explains features of secure operating system and why current systems implemented under the notion of application space security ultimately failed to safe guard the integrity and confidentiality of our assets. The article then continued with general examples of access control and cryptography implemented in the application space with no or little support from operating system and showed their vulnerabilities to attacks such as tampering, bypassing and spoofing. The article supplied real-life examples to support the evidence that building security in the application space without secure operating system is meaningless. The article raised concrete examples on mobile code security, Kerberos network authentication service, IPSEC and SSL network security protocols and firewall. The paper finally put an interesting remark that security implemented in application space without secure operating system is like “building a house in a pile of sand” and it also emphasized that secure operating system without better security on the

System software:The programs that control and manage the basic operations of a computer are generally referred to as system software. System software typically includes the following types of programs: operating systems, utility programs, software development

Operating System is a main computer program that communicates with the hardware to help the computer run.

ANSWER: Operating system exist on the grounds that they offer a sensible approach to tackle the issue of making a usable processing framework. The major objective of computer systems is to execute user programs and to make user issues simpler. Computer hardware is developed to this objective. Since exposed hardware alone is not simple to utilize, application programs are produced. These programs require basic operations, for example, those controlling the I/O devices. The regular capacities of controlling and assigning assets are then brought together into one bit of software: the operating system. Another way we

In this paper I will discuss the comparison of memory from each one of these, UNIX®, Linux®, Mac®, and Microsoft® Windows® operating systems. Each one is different from one to another. They can either be an open source operating system or closed operating system. Reading this paper, will shed some light on things people do not even understand what the operating system and memory management does.

b) 1) Take the commands one by one from the main memory and execute the necessary commands and commands.

An operating system is a set of programs that manage computer hardware resources and provide common services for application software. (Operating Systems) Without the operating system, a computer could not function. Applications would not be able to operate

Process management creates processes, and implements multitasking by switching the active process on the processor.

This paper will elaborate on the major differences of the main Operating Systems (OS), which are UNIX/Linux, Mac®, Microsoft® Windows®. The areas of discussion for this paper will be on Memory Management, Process Management, File Management, and Security for each operating system. Operating Systems (OS) for a computer is the main processing software program used to allow the computer processor to communicate with the software and hardware I/O devices. Computers as SUN, SUSE use UNIX/Linux operating system, Mac® (Macintosh) computer uses Apple operating system, and Personal Computers (PC)

Network operating system works on a server and it allows the server to manage other functions on a computer. The main purpose of a

Operating system is a platform that is found between the hardware and the user that is responsible for management and sharing of resources of the computers. Operating system has a basic function definition; it is a program making the power of the computer to be available to users by use of hardware control. Computers cannot work if there is no operating system installed in them since it hosts many applications running inside the computer while handling operations of the computer hardware. Operating systems are of many different types having various functions. This paper therefore, tends to analyze the functions of operating system.
