Diffusion and Osmosis

Diffusion and Osmosis are the two activities that preforms the role of transporting materials to or from the cell. Both are the passive transportation, that means such spontaneous process that does not needs any energy. The first one (diffusion) is the movements of molecules from the region of higher concentration ot the lower concentration trough […]

Difference Between Shared Memory and Message Passing Process Communication

Shared memory and message passing are the two methods of establishing interprocess communication. Interprocess communication is communication between the two processes of the operating system. Interprocess communication always takes place between the cooperating processes. These processes can affect the execution of other processes in the system. Or it can get affected by the other processes […]

Cancer Cells
