URL refers to the global address of a resource or document. A URL can be divided into four components: a scheme, a host, a path and a query string. A scheme represents the protocol (http, https, ftp, mailto, file etc.) to be used for accessing the information from the internet and to establish secure and smooth communication. A host or domain name (www.yahoo.com) represents the destination location for the URL. A host name consists of subdomain, second-level domain and top-level domain. In Figure 13.1, the term ‘www’ represents the subdomain, the text ‘yahoo’ indicates the domain name and the term ‘com’ represents the top-level domain. The components of domain names are separated by dots and preceded with a double slash. The path name includes the files and directory that represents the location of files in the server and are separated by slashes (/project/test.html). A query string is placed after the path and gives a string of information to the file for some purpose and contains the parameter list, which includes name and value pair (param1=value1). Each query string is preceded by a question mark and separated with an ampersand (&). The components of the URL are represented in Figure 13.1.
Implementation of Distributed Algorithms for Finite Element Analysis on a Network of Workstations

Based on information stored in the knowledge base of connectivity, the data distribution pattern can be visualized using a hidden line removal scheme. Data distribution can be displayed graphically in an interactive environment. Solid models are passed through a hidden-line filter to minimize image cluttering and improve picture quality. The net result is that all the elements belonging to the same subdomain are shown in the same color. This is helpful in the development of the domain decomposition algorithm itself. If the domain decomposition results in excessive scattering of subdomains, the algorithm needs to be improved. In our implementation, X window system (Chuang and Adeli, 1993), a network-transparent graphic window system for workstations, has been used to display the resulting image of the decomposed FE mesh.
The Internet and TCP/IP
Published in Goff Hill, The Cable and Telecommunications Professionals' Reference, 2012
The discussion so far has involved numeric IP addresses, which most users find uninformative and unappealing. For this reason, applications such as Web browsing and e-mail usually use domain names, for example, www.charityappeal.org. The top-level domain name is at the right of the domain name (“org” in this case), preceded by the second-level subdomain (“charityappeal”). The top-level domain names, and the subdomain names, are separated by dots. Application layer services resolve or translate domain names into IP addresses by making a call to a library “resolve” function. The domain name is passed as a parameter, and this function accesses the local Domain Name System (DNS) server (or name server) to carry out the translation. If this is not possible, this server accesses DNS servers at higher levels in the DNS hierarchy until the domain name is resolved.

Figure 1 illustrates the generation of a 2D curvilinear mesh for an ABCD square region with a single ideally round pore. This approach is referred to as a method of mechanical analogy [30]. First, a rectilinear mesh with nodes and total of nodes is constructed (Figure 1a). The domain is then subdivided into subdomains. As shown in Figure 1, for the case considered, with EFGH being the central subdomain and the others being framed by line segments. In this example, we transform the square EFGH into a circle, assigning displacements at the subdomain boundary. The node coordinates of the line segments are set analytically and represent kinematic boundary conditions. The coordinates of subdomain nodes are calculated by solving an elastic problem defined relative to the unknown displacements as
