WSH v Perl
Windows Script Host (WSH) and Practical Extraction and Report Language (Perl) are two types of programming language used for script writing. (Perl, 2006)
The Windows Scripting Host is a tool that provides access to objects in the Windows operating system, such as files, folders, and network items, to two built-in scripting engines. These scripting engines are for the VBScript and JScript scripting languages, which are derivatives of the full-blown Visual Basic and Java programming languages. Because VBScript and JScript are scripting languages, the programs that you can develop with them are much simpler and smaller than those that you'd develop with the full-blown programming languages. Furthermore, the scripting languages aren't as robust as the full-blown programming languages. (Schultz, 2000)
WSH is language-independent in the sense that it can make use of different Active Scripting language engines. (Windows Script Host, 2006) And although WSH enables you to run programs written in these languages, it is not a language itself. Basically, WSH is a host for users to write and execute scripts, written in a multitude of languages, in a stable environment. Another scripting host that most are familiar with is Microsoft¡¦s Internet Explorer. IE enables scripts that use the HTML object model to be displayed in a user friendly way.
An unusual aspect of WSH is that it was developed to be a general-purpose. This means that when using WSH the user has no restrictions on programming language. Windows Script Host¡¦s abilities can be divided into the following categories:
« The ability to intrinsically carry out system administration tasks.
« The ability to use COM objects to carry out system administration tasks.
« The ability to add standard programming features to WSH-compatible scripting languages.
« The ability to run command-line tools.
(Microsoft TechNet, 2006)
Windows Script Host comes with Windows, meaning that most computers already have the capability to start script writing straight out of the box. However, due to the smaller memory footprint, WSH should only be used to perform quick and easy tasks. Running your scripts via WSH is incredibly easy; because it is built in with most operating systems, the user simply double-clicks the script icon and the scripts run. WSH can be run in two separate modes within Windows. The first of these modes is the protected-mode Windows-based host, or Wscript. By running scripts in Wscript, results will appear as ¡§pop-ups¡¨ on the desktop. The other mode, real-mode command shell-based host (Cscript), allows the user to run scripts from the command line interface.

One of the important components of software engineering is the platforms. There are many various types of computing platforms. A few of these include AmigaOS, Linux, Windows, Solaris. These examples are just a few of many different computing platforms. The types of computing platforms can be differentiated into three different categories, which include operating-system examples, software frame work examples, and also hardware examples. Each of the different platforms has slightly different requirements and means of maintenance. Even the required standards for the platforms differentiate depending on which platform being used. Platforms are a vital part of systems and for applications, and are available in many various forms. The basis of this paper is mainly to observe the differences and similarities of four of these platforms. The particular platforms being compared and contrasted with each other include: Linux, Microsoft Windows, UNIX, and Macintosh. The purpose is to look at the purpose of each of these platforms and also to perceive the advantages and disadvantages of each.
The Ada language is the result of the most extensive and most expensive language design effort ever undertaken. The United States Department of Defense (DoD) was concerned in the 1970¡¦s by the number of different programming languages being used for its projects, some of which were proprietary and/or obsolete. Up until 1974, half of the applications at the DoD were embedded systems. An embedded system is one where the computer hardware is embedded in the device it controls. More than 450 programming languages were used to implement different DoD projects, and none of them were standardized. As a result of this, software was rarely reused. For these reasons, the Army, Navy, and Air Force proposed to develop a high-level language for embedded systems (The Ada Programming Language). In 1975 the Higher Order Language Working Group (HOLWG) was formed with the intent of reducing this number by finding or creating a programming language generally suitable for the department's requirements.
As the internet is becoming faster and faster, an operating system (OS) is needed to manage the data in computers. An Operating system can be considered to be a set of programed codes that are created to control hardware such as computers. In 1985 Windows was established as an operating system and a year earlier Mac OS was established, and they have dominated the market of the computer programs since that time. Although, many companies have provided other operating systems, most users still prefer Mac as the most secured system and windows as it provides more multiple functions. This essay will demonstrate the differences between windows
The programming language C++ can be used in many ways. It has exploded into the gaming community allowing PC game programmers to have access to a stabile, yet powerful, programming language, utilizing as little code as possible. It has also been used in other commercial software, such as word processors, audio players, screen savers, and other computer desktop tools.
Most programming languages—such as C, C++, and Fortran—use compilers, but some—such as BASIC and LISP—use interpreters. An interpreter analyzes and executes each line of source code one-by-one. Interpreters produce initial results faster than compilers, but the source code must be re-interpreted with every use and interpreted languages are usually not as sophisticated as compiled languages.
Many different types of programming languages are used to write programs for computers. The languages are called "codes". Some of the languages include C++, Visual Basic, Java, XML, Perl, HTML, and COBOL. Each of the languages differs from each other, and each is used for specific program jobs. HTML and JAVA are languages used to build web pages for the Internet. Perl and XML can produce codes that block students from getting on certain inappropriate web pages on their school server. One of the most prominent programming languages of the day would have to be C++.
The following report details some of the more common malicious code specifically viruses, explaining some of the damage, which these very powerful viruses can inflict on to any computer that it is not well prepared for this kinds of attacks.
The language itself borrows much syntax from C and C++ but has a much simpler object model and does away with low level tools like programmer-manipulable pointers.
Along with XML comes a family of helpful resources designed to automate frequently used tasks and offers services to make writing the language efficient and user friendly.
Malicious code, also known as malware, installed on a computer provides an attacker with the control over this machine. Therefore, malware can be defined as “a set of instructions that run on your computer and make your system do something that an attacker wants to do”. It is more common to see malicious code to be implemented in binary executable files. However, it can be implemented in almost any computer language. Attackers have used a huge number of scripting languages, word processing macro languages and a h...
Computer programming servers the purpose of finding a sequence of instructions that are able to automate the performance of specific tasks or solve defined problems. Programming process therefore requires expertise in a variety of other subjects such as the knowledge of application domains, formal logic and specified algorithms. Computer programming is usually regarded as one phase in a software development process within software engineering.
Within this report is information on how Java Script is used on the Internet. This report will contain information that will help you learn about Java Script and its uses on the Internet. It mentions what Java Script is, where it originated and what some of its uses are.JavaScript is a loosely typed scripting language that resembles the programming language C. It is designed to be an extension to HTML and is usually included within HTML scripts. Java Script is object-oriented and has block-structuring features. The main feature of Java Script is that it lets you build interactive web pages.
