Centralization And Desentralization


Centralization
Centralization is focusing all authority to a small number of managers or yangberada at the top of the organization structure. Maybe now I'll take pembacauntuk look back or in ancient times. If we look at the development of science and information systems teknologiinformasi, most enterprise applications are built ad-hoc development dala sehinggatidak wonder we often encounter the phenomenon of patchy application system. Dandalam company or department in ancient times often build their own system-sendiriuntuk supporting functional activities, such as accounting and financial information systems, marketing and sales systeminformasi, operational information systems, and so forth. In awalnyapara companies do not feel that this system brings problems. Therefore, systemini still used. However, in line with the times and teknologiinformasi developments and business world, many companies are beginning to realize that the system is already tidakcocok because of the problems in the company when they want to drain sebuahdata or information from one to the other. Communication error occurs due to technical differences such problems adanyasejumlah standards, protocols, technologies, methods and other lain.Oleh Therefore, companies began to glance at the concept of the centralized system because they sangatmembutuhkan a large system a unified and integrated with each other and others. Ataukarakteristik feature of the system of centralization are as follows:
Strategies, policies and approach to information management policies seragamdan standard for all organizational units with a tendency to be top down governance  Decisions related to the type of system, type of application, database standards, hakakses, hardware specifications and infrastructure, and other determined by the centre Information technology units have centre power and authority a much larger and higher than the unit similiar that exist in different branches of the company or business unit Computing power is likely to be placed at the center of a number of marked with installed a powerful servers and warehouse file the consolidation of data berisiseluruh cabang.Selain offices, the centralized system has several advantages, namely:
Guarantee the formation of a holistic and coherent system across tataranorganisasi because it is standardized and centralized Exchange of file and information can be easily karenakeseragaman technology primary and secondary data storage. The potential  anarchy as a phenomenon  patchy and kesulitanmembangun interface of a number of systems that spread to direduksiseminimum possible, and other sebagainyaTetapi not just the excess, system centralization it also has a lot kelemahandimana this weakness very annoying and impede progress perusahaan.Kelemahan-weakness among other:
The tendency is excessive control and information management are too strict hinggaterjadi a fairly rigid and hierarchical Focus was focused more on  conformity  or adherence to standard procedures, thereby reducing a number of initiatives that sometimes can be benefit for company,
Because usually leads to a certain standard, often perludikeluarkan cost is relatively much more expensive than the non-standard. Because information technology comprises a number of components that are diverse, not necessarily the individual components selected are the best (karenayang important for management is the similarity standard so terkadangkinerja or diminished performance), Sometimes found in the development of sophisticated new technologies danberguna for the company, but due to the company's standard specifications beyond those opportunities just released, Nature or  the characteristics of the development of information technology that completely open system and open standard' create a centralized system yet tentumemiliki competitive advantage compared to other approaches, Assumptions are always used in the centralized system is kesamaanfasilitas and performance across the company's business units, but for the archipelago like Indonesia and infrastructure issues digitaldivide 'major obstacles that often hinder the effectiveness kinerjasistem, and so forth
Decentralization
A decentralized organization is one in which decision making is not confined to a few top executives but rather is throughout the organization, with managers at various levels making key operating decisions relating to their sphere of responsibility. Decentralization is a matter of degree, since all organizations are decentralized to some extent out of necessity. At one extreme, a strongly decentralized organization is one in which even the lowest-level managers and employees are empowered to make decisions. At the other extreme, in a strongly decentralized organization, lower-level managers have little freedom to make decisions. Although most organizations fall somewhere between these two extremes, there is a pronounced trend toward more and more decentralization.

Advantages/Benefits of Decentralization:
Decentralization has many advantages/benefits, including:
  1. Top management is relieved of much day-to-day problem solving and is left free to concentrate on strategy, on higher level decision making, and coordinating activities.
  2. Decentralization provides lower level managers with vital experience in making decisions. Without such experience, they would be ill-prepared to make decisions when they are promoted into higher level positions.
  3. Added responsibility and decision making authority often result in increased job satisfaction. Responsibility and the authority, that goes with it makes the job more interesting and provides greater incentives for people to put out their best efforts.
  4. Lower level managers generally have more detailed and up to date information about local conditions than top managers. Therefore the decisions of lower level management are often based on better information.
  5. It is difficult to evaluate a manager's performance if the manager is not given much latitude in what he or she can do.
Disadvantages of Decentralization:
Decentralization has four major disadvantages:
  1. Lower level managers may make decisions without fully understanding the "big picture." While top level managers typically have less detailed information about local operations than the lower level managers, they usually have more information about the company as a whole and should have a better understanding of the company's strategy.
  2. In a truly decentralized organization, there may be a lack of coordination among autonomous managers. This problem can be reduced by clearly defining the company's strategy and communicating it effectively throughout the organization.
  3. Lower-level managers may have objectives that are different from the objectives of the entire organization. For example, some managers may be more interested in increasing the sizes of their departments than in increasing the profits of the company.                    To some degree, this problem can be overcome by designing performance evaluation system that motivate managers to make decisions that are in the best interests of the organization.
  4. In a strongly decentralized organization, it may be more difficult to effectively spread innovative ideas. Someone in one part of the organization may have a traffic idea that would benefit other parts of the organizations, but without strong central direction the idea may not be shared with, and adopted by other parts of the organization.

Server And Client


Server
In most common use, a server is a physical computer (a computer hardware system) dedicated to running one or more services (as a host), to serve the needs of the users of other computers on the network. Depending on the computing service that it offers it could be a database server, file server, mail server, print server, web server, gaming server, or some other kind of server. In the context of client-server architecture, a server is a computer program running to serve the requests of other programs, the "clients". Thus, the "server" performs some computational task on behalf of "clients". The clients either run on the same computer or connect through the network. In the context of Internet Protocol (IP) networking, a server is a program that operates as a socket listener.  Servers often provide essential services across a network, either to private users inside a large organization or to public users via the Internet.

Usage

The term server is used quite broadly in information technology. Despite the many server-branded products available (such as server versions of hardware, software or operating systems), in theory any computerised process that shares a resource to one or more client processes is a server. To illustrate this, take the common example of file sharing. While the existence of files on a machine does not classify it as a server, the mechanism which shares these files to clients by the operating system is the server. Similarly, consider a web server application (such as the multiplatform "Apache HTTP Server"). This web server software can be run on any capable computer. For example, while a laptop or personal computer is not typically known as a server, they can in these situations fulfill the role of one, and hence be labelled as one. It is, in this case, the machine's role that places it in the category of server. In the hardware sense, the word server typically designates computer models intended for hosting software applications under the heavy demand of a network environment. In this client–server configuration one or more machines, either a computer or a computer appliance, share information with each other with one acting as a host for the other. While nearly any personal computer is capable of acting as a network server, a dedicated server will contain features making it more suitable for production environments. These features may include a faster CPU, increased high-performance RAM, and increased storage capacity in the form of a larger or multiple hard drives. Servers also typically have fault tolerant features, such as redundancy in power supplies, storage (as in RAID), and network connections. Servers became common in the early 1990s as businesses increasingly began using personal computers to provide services formerly hosted on larger mainframes or minicomputers. Early file servers housed multiple CD-ROM drives, which were used to host large database applications. Between the 1990s and 2000s an increase in the use of dedicated hardware saw the advent of self-contained server appliances. One well-known product is the Google Search Appliance, a unit that combines hardware and software in an out-of-the-box packaging. Simpler examples of such appliances include switches, routers, gateways, and print server, all of which are available in a near plug-and-play configuration. Modern operating systems such as Microsoft Windows or Linux distributions rightfully seem to be designed with a client–server architecture in mind. These operating systems attempt to abstract hardware, allowing a wide variety of software to work with components of the computer. In a sense, the operating system can be seen as serving hardware to the software, which in all but low-level programming languages must interact using an API. These operating systems may be able to run programs in the background called either services or daemons. Such programs, such as the aforementioned Apache HTTP Server software, may wait in a sleep state for their necessity to become apparent. Since any software that provides services can be called a server, modern personal computers can be seen as a forest of servers and clients operating in parallel. The Internet itself is also a forest of servers and clients. Merely requesting a web page from a few kilometers away involves satisfying a stack of protocols that involve many examples of hardware and software servers. The least of these are the routers, modems, domain name servers, and various other servers necessary to provide us the world wide web.

Client
 Client is an application or system that accesses a service made available by a server. The server is often (but not always) on another computer system, in which case the client accesses the service by way of a network.[1] The term was first applied to devices that were not capable of running their own stand-alone programs, but could interact with remote computers via a network. These dumb terminals were clients of the time-sharing mainframe computer. The client–server model is still used today. Client and server can run on the same machine and connect via Unix domain sockets, or other inter-process communication techniques such as shared memory, or named pipes. Using Internet sockets a user may connect to a service operating on a possibly remote system through the Internet protocol suite. Servers set up listening sockets, and clients initiate connections that a server may accept. Web browsers are clients that connect to web servers and retrieve web pages for display. Most people use email clients to retrieve their email from their internet service provider's mail storage servers. Online chat uses a variety of clients, which vary depending on the chat protocol being used. Multiplayer online games may run as Game Clients on each local computer. Increasingly, existing large client applications are being switched to websites, making the browser a sort of universal client. This avoids the hassle of downloading a large piece of software onto any computer you want to use the application on. An example of this is the rise of webmail. In personal computers and computer workstations, the difference between client and server operating system is often just a matter of marketing - the server version may contain more operating system components, allow more simultaneous logins, and may be more expensive, while the client version may contain more end-user software.
Fat
A fat client, also known as a rich client or thick client, is a client that performs the bulk of any data processing operations itself, and does not necessarily rely on the server. The fat client is most common in the form of a personal computer, as the personal computers or laptops can operate independently.Programming languages and/or development tools for rich clients typically include Delphi, .NET Framework, Java and Visual Studio.

Thin
            A thin client is a minimal sort of client. Thin clients use the resources of the host computer. Athin client's job is generally just to graphically display pictures provided by an application server, which performs the bulk of any required data processing. Programming environments for thin clients include JavaScript/AJAX (client side automation), ASP, JSP, Ruby on Rails, Python's Django, PHP and other (depends on server-side backend and uses HTML pages or rich media like Flash, Flex or Silverlight on client).
