Major Computer System Failures Caused by Software Bugs In early 2006 problems in a state's financial monitoring software resulted in incorrect election candidate financial reports being made available to the public. The state's election finance reporting web site was shut down until the software was repaired. Trading on a major Asian stock exchange was brought to a halt in November of 2005, reportedly due to an error in a system software upgrade. The problem was rectified and trading resumed
MySQL Workbench vs. SQL Server 2008 MySQL Workbench and SQL Server 2008 have the same common goal, but how each program approaches that goal is different. There are some things that MySQL Workbench can do that SQL Server cannot. But, of course, Oracle can do everything. There are some general differences between MySQL and SQL Server for example: look, feel, methods, security, backup and recovery. These are the things this paper will discuss. MySQL Workbench offers a MySQL Enterprise Backup GUI interface
BoundsChecker Introduction: BoundsChecker is a utility for checking applications for bugs like memory overwrites, reading not initialized memory, use of dangling pointers and much more.It is a memory checking and API call validation tool used for C++ software development with Microsoft Visual C++. BoundsChecker is an indispensable tool for Windows programming. It finds errors very efficiently (including tons in Microsoft's code!!). Its main focus is on finding memory leaks. Creation and Version History:
Linux Networking Capabilities Linux is a Unix clone written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX compliance. It has all the features expected in a modern fully-fledged Unix, including true multitasking, virtual memory, shared libraries, demand loading, shared copy-on-write executables, proper memory management and TCP/IP networking. It runs mainly on 386/486/586-based PCs, using the hardware facilities of the
In today’s society software plays a major part of our lives. The kind of software depends on what we are trying to accomplish. Can life exist without it? Yes! But it would be difficult. Simply put we are a nation of instant gratification; we want what we want when we want it. However understanding the different roles software play in everyday life is how we identify with our computers. Let’s start by defining a few words the definition for Software means computer instructions or data
Compiler Compiler, in computer science, computer program that translates source code, instructions in a program written by a software engineer, into object code, those same instructions written in a language the computer's central processing unit (CPU) can read and interpret. Software engineers write source code using high level programming languages that people can understand. Computers cannot directly execute source code, but need a compiler to translate these instructions into a low level language
Task 1.2 Explain the hardware, software and peripheral components of a computer system and the functional relation between these components. Hardware Hardware refers to tangible objects like disks, disk drives, display screens, keyboards, printers, boards, power supply and system unit (graphic cards, sound cards, memory, motherboard and chips). The motherboard store many components (microprocessor, RAM, controller…) and connect every other equipment. The microprocessor is the brain of the computer
SDLC (Software Development Life Cycle) is a process which consists of series of well-planned actions to develop or make changes in the software products. This chapter provides description on the SDLC basics, SDLC models and their application in the software industry. This gives directions for the quality stakeholders of any Software project and the product or project managers. SDLC, Software Development Life Cycle is a process generally deployed by software industry to design, develop and test high
Software Testing Software development follows a specific life cycle that starts with designing a solution to a problem and implementing it. Software testing is part of this software life cycle that involves verifying if each unit implemented meets the specifications of the design. Even with careful testing of hundreds or thousands of variables and code statements, users of software find bugs. “Software testing is arguably the least understood part of the development process” and is also a “time-consuming
Kevin Mitnick Hacking has been around since the birth of computers. When the term hacking was first used, its meaning was not that of how we think of it today. At the origins of computing, a hacker was considered to be just a "creative programmer (Baase, 2003)." Early forms of computer games as well as the beginnings of operating systems were discovered and created by these original hackers. These hackers plunged into systems as a way of an intellectual challenge and to aspire to gain knowledge
Pascal programming language was designed in 1968, and published in 1970. It is a small and efficient language intended to encourage good programming practices using structured programming and data structuring. Pascal was developed by Niklaus Wirth. The language was named in honor of the French mathematician and philosopher Blaise Pascal. In 1641, Pascal created the first arithmetical machine. Some say it was the first computer. Wirth improved the instrument eight years later. In 1650, Pascal left
Reflection of software engineering in Software Development Lifecycle (SDLC) The software engineering provides techniques to facilitate the development of computer projects. It deals with systematic and disciplined approach to the work and use of appropriate tools and optimum solutions for the problems to be solved. Software engineering uses the design principles and best practices for building quality software In a nutshell, it is the use of technologies and practices from computer science, design
Introduction Decades of operating system development and a collection of systems and features from many other systems combined with many unique ideas and implementations resulted in the development of Apple, Inc.'s OS X family. It is necessary to examine the older systems of OS X as well the progress of the system to understand the different technologies and how they interact. To secure and troubleshoot problems it is of great importance to understand the how and often the why of OS X technology
Procedural Programming Procedural programming works like a step by step guide. You have to create a sequence of instructions which tells the computer what to do first, second, third and so on. Examples of a procedural programming language would be Pascal, Turbo Pascal and Basic. Procedural programming would be used when it is necessary to complete steps in a program and is only used when a user is about to do a certain task. An example of a procedural programming scenario would be that if a user
Living in a modern society, technology continues to advance in ways that many would think impossible many years ago. Technology continues to aid the human race in many ways; such as making communication possible across continents within seconds, helping develop new medicines for previously incurable diseases, and completely tasks that would take hours to do by hand. However, technology does not just develop on its own as an intelligent being, but it continues to be molded by those that work in the
E.2.3.13 My selection of 8051 microcontroller was on the basis of following features: Speed, packaging, power consumption, RAM & ROM, I/O pins, chip timer, ease of up gradation to higher performance versions, cost per unit. Availability of a debugger, an emulator, a C- language compiler which is code-efficient, an assembler, and obviously technical support. It should be readily available. In fact the 8051 is the most procurable 8-bit microcontroller. C.E.2.3.14 The circuit diagram I have
capability of a computing system. Without a high performance, energy-efficient interconnect, an Exascale system would be more like the millions of individual computers in a data center, rather than a supercomputer. Programming tools, compilers, debuggers, and performance enhancement tools will all play a big part in how productive a scientist is when working with an Exascale system. Without increasing programming
One of the hottest topics in privacy is regarding our phone conversation with others. It doesn't take a whole lot these days to be in someone's business, in their conversation, breaking the law of privacy with out spending that much time and money. "…Compared to an average monthly phone bill of seventy dollars, the option to wiretap the average phone line is probably worth less than twelve cents a month to police and spy agencies."1 These days, when information is transferred from one person to another

Online chat may refer to any kind of communication over the Internet that offers a real-time transmission of text messages from sender to receiver. Chat messages are generally short in order to enable other participants to respond quickly. Thereby, a feeling similar to a spoken conversation is created, which distinguishes chatting from other text-based online communication forms such as Internet forums and email. Online chat may address point-to-point communications as well as multicast communications
