Pemrograman socket merupakan pemrograman yang digunakan untuk melakukan komunikasi proses (process-to-process) dalam sebuah jaringan. Selain komunikasi proses, dalam sebuah jaringan komputer juga melakukan komunikasi host (host-to-host). Dalam pengujian pemrograman socket dapat dilakukan dengan menggunakan jenis  socket networking  sock_stream pada client ke server dengan menggunakan alamat proses (IP dan Port) pada komputer yang sama dengan direktori yang sama dan yang berbeda serta dengan komputer lain yang berbeda. Untuk pengujian, akan dibuat server dan client yang akan melakukan komunikasi proses. Pada server dan client, socket yang digunakan adalah AF_INET. Pada komunikasi proses di server, mula-mula dilakukan proses pembuatan socket dengan fungsi call socket(), kemudian server mengikat socket yang dibuat tadi dengan jaringan berdasarkan nomor local address dan port dengan fungsi call bind(). 

Hospital is one of type effort for service that is now stays in very tightening emulation climate. Struggle to create recuring business with customeroccupies central point in the effort hospital to exeed at long-range emulation. Service quality and cutomer value becomes thing which necessary for hospital. This research analysis factors influence customer satisfaction to create hospital service reference enthusiasm in Hospital PKU Muhamadiyah Gubug Kabupaten Grobogan.Research problem is existence of gap or debate at antecedent research would consequence and from customer satisfaction. Other problems is thehappening of downdraft of number of outpatients continually at last four months and existence of improvement of number sighs from patient. Respondent in this research 120 patients with sampling method applies acidental sampling. This research applies analysis Structural Equation Modeling (SEM) what implemented through program AMOS as a means of assists its the analysis.Result of research proves that service quality, cutomer value and excellence of product has positive influence and signifikan to customersatisfaction. Hereinafter, customer satisfaction of influence positive and signifikan to hospital service reference enthusiasm. Excelsior service quality and cutomer value has customer satisfaction of excelsior and causes home service reference enthusiasm which excelsior.

This study intent to search several variables’ effect which is probably able to rise loyalty and firm performance. The study used several customer of WAN HAI Ltd in Midle of Java as sample. Data analyze instrument used by the writer is AMOS 4.Data analyze result shows that the research model has well appropriateness andall hypothesis of the study are able to be evidenced. Summary said that satisfaction,reputation, price, are positively effected to loyalty, and loyalty are positively effected tofirms performance.Result of research proves that satisfaction, reputation, and price has positive influence and significant to loyalty. Loyalty has positive influence and signifaicant to firm performance. Managerial implication given to the company is suggestion or input to management to concern the price factors, as it is the most dominant factor effected to loyalty. The research’s limitation is that it is case study so that the result is not able to be generalized

When creating databases for GIS-applications often existing maps are scanned and vectorised for used. However, vectorisation becomes obsolete when GIS-objects can be referred to both in theme and geometry in a raster environment. This article shows to use model spatial data raster and vector for GIS - applications in both the graphical and image structure. Geographical data must first be converted into a computer- readable format before it can be used in a GIS. Spatial data are "elements that can be stored in map form." These elements correspond to a uniquely defined location on the Earth's surface. Spatial data have also been describe as “any data concerning phenomenon a really distributed” in two or more dimensions. (Peuquet and Marble, I990.) Data model is the rules to convert real geographical variation into discrete objects. There are two main GIS data models - vector and raster. Each of the two data models has specific types of data, analysis and displays that can handle better than the other system. The vector model represents geographical reality as a series of discrete objects or features, classified as points, line's or areas (polygons). The geographical co-ordinates describing the locations of these features are stored in the computer database which lies at the heart of the GIS. In the raster model a regular grid of cells, or pixels, is used to encode the features found on the earth's surface. Each pixel has a number associated with it representing; the value of a geographical phenomenon, such as terrain elevation, soil type or biomass. Layers of raster grids covering the same region can be built up to represent further variables.
