This option has a lot of disadvantages, the main one being high requirements for the bandwidth of data transmission channels. Today we will try to connect to a graphical Linux desktop using RDP (Remote Desktop Protocol). VNC is based on the transmission of arrays of pixels using the Remote Framebuffer (RFB) protocol, while RDP allows more complex graphics primitives and high-level commands to be sent. ...

Nonlinear differential equations, discreteness of space-time and epsilon product


All the content of this article is the result of solving the problem of level first year University course in mathematical analysis. Here we introduce a new work for lattice functions (we will call it Epsilon-multiplication), which gives us the opportunity to see an interesting connection between the integral-differential equations (including nonlinear) and recurrence relations. This allows an unusual angle to look at some methods of their solution. But, what I find particularly interesting is...
