Microsoft Strategic Management

Background It’s the 1970s. At work, we rely on typewriters. If we need to copy a document, we likely use a mimeograph or carbon paper. Few have heard of microcomputers, but two young computer enthusiasts, a nineteen year old kid and his twenty-two year old business partner (Bill Gates and Paul Allen) sold their first program to a little computer company in Albuquerque, New Mexico. The program was called BASIC, and it was the start of this company we call Microsoft. We see that personal computing is a path to the future. In 1975, Gates and Allen form a partnership called Microsoft. Like most start-ups, Microsoft begins small, but has a huge vision—a computer on every desktop and in every…

Operating System Integration

There is no universal definition of what is an operating system. An “operating system (OS) is a set of basic programming instructions to computer hardware, forming a layer of programming code in which most other functions of the computer are built” (Palmer and Walters, 2). Another definition of operating system “is a program that acts as an intermediary between a user of a computer and the computer hardware” (Silberschatz, Abraham, et al. 3). All other software runs under the operating system’s control, accessing the hardware through the operating system and following rules imposed by the operating system. Because the operating system serves as a hardware/software interface, application programmers and users rarely if ever must communicate directly with the hardware, and…

Image Morphing

Morphing is a special effect in motion pictures and animations that changes (or morphs) one image into another through a seamless transition. Most often it is used to depict one person turning into another through technological means or as part of a fantasy or surreal sequence. Traditionally such a depiction would be achieved through cross-fading techniques on film. Since the early 1990s, this has been replaced by computer software to create more realistic transitions. | Three frames form a morph from George W. Bush to Arnold Schwarzenegger showing the midpoint between the two extremes Though the 1986 movie The Golden Child implemented very crude morphing effects from animal to human and back, the first movie to employ detailed morphing was…

Open vs Closed Systems

The state of Kansas defines OSS (Open Sourced Software) as software for which the source code is freely and publicly available, though the specific licensing agreements vary as to what one is allowed to do with that code. The book defines open source operating systems as those made available in source-code format rather than binary code. Closed source is exactly the opposite. Closed source is proprietary software that is only made available in binary code which is very difficult to reverse engineer. Open-source code is exactly what the programmer developed including all of the comments and notes. Open-source is most commonly confused with free software although the difference is very miniscule however strongly opposed. When all of these ideas are…

Memory Management Comparison

When discussing the differences in memory management practices between Windows and Linux environments, an understanding of what they do is necessary. Memory management systems are core aspects of operating systems. Managing a memory hierarchy of random access memory (RAM) and available hard disks is only its basic function. They perform other critical tasks such as the allocation and de-allocation of memory for processes that take care of logistics and implementing virtual memory via the hard disk to perform as additional RAM. Maximum optimization of the memory system is crucial as it greatly affects the overall speed and performance of the system. An important concept in memory management is virtual memory. The basic idea behind this is providing an application the…

1.0 Introduction Meaning of open source software Open source software (OSS) is defined as computer software for which the source code and certain other rights normally reserved for copyright holders are provided under a software license that meets the Open Source Definition or that is in the public domain. This permits users to use, change, and improve the software, and to redistribute it in modified or unmodified forms. Meaning of hardware A computer’s hardware consists of the physical components necessary to operate and interact with a computer. Since a computer’s primary language is binary, devices are necessary to convert our input into that language. The binary code coming out of the computer must also be translated into something usable for…

Open and Closed Source and What It Means

Open-Source means it is free. No one owns it, so there is no source code, no key code, and no licensing to purchase. When Linus Torvalds created Linux, he determined that the more people or, the more minds delving into the software can make the system more creative, more improved, and the possibilities are endless. Thus, he gave Linux to the world as a free open-source operating system (“Damicon; Linking The Left Brain And The Right Brain: Open Vs. Closed Source”, 2003-2009). Open-Source is defined by the code or source code is accessible to person or persons who essentially use it or in IT definition: end-user. The user can revise and refashion or change it, as long as he or…

Operating System Security Flaws

As basic users, security is one feature that most of us overlook when it comes to operating systems until it is too late. In this paper we will discuss the security flaws within the Windows Operating system, and then discuss countermeasures to fix the system flaw. We will first look at some known flaws in Windows 7 and Windows 8. An Information Security Engineer at Google had decided to reveal a flaw that affected two of Microsoft’s newest operating systems that allowed attackers to obtain higher privileges on an unpatched computer. The vulnerability was caused due to an error within the ‘win32k.sys’ when it processes certain objects and it can be exploited to cause a crash or perform arbitrary code…

History Of Data Processing

Data processing is a shop that works in many different working fields. One thing you do in data processing is learning to computer programming. In my shop we are learning to program in Visual Basic and QuickBasic. Programming is used to tell a computer what to do. Using code you can make programs that can answer math problems, which would take someone, days to calculate in a brief second. In data processing we also learn to word process. Word processing is taking written text and being able to save and manipulate the text as desired. We also use databases in organizing large sums of information. Another thing we learn to do is make web sites, using Hypertext Markup Language (HTML)….
