Modern Computer Network

Modern network
Today's modern network programming based on client / server model. In most cases, the server typically sends data, while the client received it. A discussion of the model Client / Server will not be separated from the concept of a distributed system. For client / server is the basic model of a distributed system.
Client-Server is a network architecture which separates the client (usually applications using GUI) to the server. Each client can request data or information from the server.

Wireless Hotspot
Now we can turn a smartphone into a wireless access poimt. The more recent, the easier the process, but the price is also more expensive. Android 2.2 (Froyo) support Wi-Fi hotspot and tethering. Hotspot allows us to create a wireless access point 3G or 4G (depending on smartphones) with multiple devices (laptops, tablets) can be connected. The number of supported devices depending on the model smartphone. Wi-Fi hotspot capability is also available on the iPhone (starting iOS 4.3) and the windows phone 7.5

Bluetooth TetheringUsing Bluetooth to share an Internet connection with a smartphone is less known. Some tethering applications provide options such as Wi-Fi or Bluetooth that makes you may have to root your smartphone to do so. In this way brings us to the "alternative connection" or tethering a smartphone and laptop without the consent of the operator.
Connection Alternatives
One alternative application called Android Wifi Tether. To install (or most of the applications the like), you need to root or jailbreak your smartphone. His rooting process vary, depending on the model of your smartphone. If you do rooting or jailbreak, your smartphone will void the warranty. Besides, you probably will not find this app in the Android Market because some operators block. To get it, you must do a "side loading", namely men-dowload it from the developer's website. USB tethering other applications that work without root access is PdaNet.
Fifth generation computer (future) Many advances in the field of computer design and semkain technology enables the creation of fifth-generation computers. Two engineering advances which are mainly parallel processing capabilities, which will replace the non-Neumann model. Non Neumann model will be replaced with a system that is able to coordinate many CPUs to work in unison. Another advancement is the superconducting technology that allows the flow of electrically without any obstacles, which will accelerate the speed of information. Japan is a country well known in the jargon of socialization and the fifth generation computer project. ICOT institute (Institute for New Computer Technology) was also formed to make it happen. Many news stating that the project has failed, but some other information that the success of this fifth generation computer project will bring new changes in the world paradigm of computerization. We are waiting for information is more valid and fruitful.
