A key requirement of the software design of a computer-based system is to transform basic requirements into an architecture that describes the software 's top-level structure and identifies its components. Accomplishment of this requirement is through architectural design, providing a blueprint for developing the framework of the software (Mattsson, Lundell, Lings, & Fitzgerald, 2009). The establishment of the framework involves examining the software requirements document and designing a model

four main types of network operating systems, which are Windows Server, Linux, OSX and UNIX. These different types of operating systems could all be used in Kate’s computers but some will be more efficient for what Kate’s business will need. Windows operating system was developed by Microsoft to run on personal computers, so can be used by anybody for their various different uses, which is why it is the

the Intel processor, introduced Windows, its own graphical operating system. Apple litigated for years, in vain, to stop Microsoft from copying the “look and feel” of its operating system, though the Mac OS itself drew... ...million copies of the program and defeated rival operating systems such as CP/M, which it displaced in the early 1980s, and later IBM OS/2. Microsoft deepened its position in operating systems with Windows, a graphical user interface whose third version, released in 1990, gained

components. Operating Systems and Application Software When computers started out, customised programs used to be written and run at a very primitive level. This involved manipulation of bits and bytes using numeric instructions called “machine code”. Eventually, symbolic languages were developed that made this manipulation easier. However, as computers became more complex, it seemed senseless for each program to repeat the same code that handled “low level” tasks like reading and writing to disk, altering

Introduction To Programming Language WHAT IS PROGRAMMING? “COMPUTER PROGRAMMING IS THE ART OF MAKING A COMPUTER DO WHAT YOU WANT IT TO DO” A program is aaa collection of instructions written in any programming language. They tell a computer how to perform a some task. It is just like a recipe which tells us how to prepare a particular dish and also describes all its ingredients and the steps to follow. Programming is also very similar in concept. WHAT IS LANGUAGE? Language is the medium

1. During the install, the option to sync with NTP (Network Time Protocol) server was checked. From a security perspective, why is it important for a system to keep accurate time? UNIX systems base their notion of time on interrupts generated by the hardware clock. Delays in processing these interrupts because UNIX systems clocks to lose time slowly but erratically. These small changes in timekeeping are what the time scientist call jitter. The Time protocol provided a server's notion of time in

“windows” displaying the contents of electronic folders and files with the click of a mouse button, rather than typing commands and directory paths at a text prompt. Subsequent versions introduced more functionality including Windows File Manager, Program Manager, and print manager along with a much powerful interface. Microsoft developed Windows packages that mainly aimed for businesses. In 1995 windows released the full version of ‘Windows 95” and offered built in internet support including the world

Analysis of Internet Protocols and Infrastructure Introduction: Network: Anything reticulated or decussated at equal distances, with interstices between the intersections. - A Dictionary of the English Language SECTION : 1 1.1 WHAT IS A NETWORK? A) What is a network? A network is simply a collection of machines connected in some way that allows them to communicate with each other and share information. To do this the machines have to be connected

configurable, which makes identifying the trojan by the port number difficult. There are no control mechanisms available which can prevent a trojan from using an specific port. If a trojan does use the port 80, for instance, a novice user could imagine the program is a webserver, and may even simply ignore the port. 10. When you identify a known software vulnerability, where can you go to assess the risk impact of the software vulnerability? Nessus can detect thousands of problems, and it classifies each as
