Compression mechanism is a decision to find the process of break-even point. The error in the application of tolerances required, the compression can indeed reduce the amount of data required. However, the implementation of data compression algorithm, the calculation inevitably introduces extra energy overhead.In mechanics, compression is the application of balanced inward (pushing) forces to different points on a material or structure, that is, forces with no net sum or torque directed so as to reduce its size in one or more directions. It is contrasted with tension or traction, the application of balanced outward (pulling) forces; and with shearing forces, directed so as to displace layers of the material parallel to each other. The compressive strength of materials and structures is an important engineering consideration.
