power supply for the Intel Platform one day in the future.Programmable substances: computers with random shapesIntel researchers are also studying how to use millions of tiny intelligent components called catom to make materials that can change shapes. If it is used to replace existing materials used by components such as the housing, display, and keyboard of a computing device, this technology can change the physical shape of the device to adapt to specific usage. For example, when a mobile co

SSL (Secure Socket Layer) is a standard for Secure Web communication proposed by Netscape. In general network protocol applications, data is packaged several times from top to bottom in the machine, and then enters the network. If these packets are intercepted, it is easy to obtain the data in the network protocol.
SSL is the protocol generated to encrypt the data. It can be understood as a layer between the bit and the application layer and TCP/IP. The data is e
