“memory” to refer to RAM (Random Access Memory). A computer uses RAM to hold temporary instructions and data needed to complete tasks. This enables the computer’s CPU (Central Processing Unit), to access instructions and data stored in memory very quickly. A good example of this is when the CPU loads an application program – such as a word processing or page layout program – into memory, thereby allowing the application program to work as quickly and efficiently as possible. In practical terms, having the program loaded into memory means you can get work done more quickly with less time spent waiting for the computer to perform tasks.

During the functioning of a computer. The first stage (things to work upon) is called input stage, the second stage (the actual work being performed) is called process stage and the third stage (the result) is called output stage. Certain input is needed to accomplish a task, a process is carried out on the input to obtain the output. Every task follows this Input-Process-Output cycle (IPO cycle in short). A computer follows the I-P-O cycle that is; it needs certain input, carries out a process and produces the output.

In materials science, a dislocation or Taylor's dislocation is a crystallographic defect or irregularity within a crystal structure. ... Some types of dislocations can be visualized as being caused by the termination of a plane of atoms in the middle of a crystal.

matter becomes a conductor of elctricity when it have free electrons. the free electrons helps in the easy conduction of electricity

In materials science, a slip system describes the set of symmetrically identical slip planes and associated family of slip directions for which dislocation motion can easily occur and lead to plastic deformation.

No microscope is powerful enough to see the structure of an atom, though recent work has developed methods of seeing individual atoms and molecules with atomic force microscopes.

The unit cell of a ccp arrangement of atoms is the face-centered cubic (fcc) unit cell. ... The 74% packing efficiency is the maximum density possible in unit cells constructed of spheres of only one size. Most crystalline forms of metallic elements are hcp, fcc, or bcc

Space lattice: It the Three dimensional arrangement of points in space. Unit cell: It is a smallest geometrical figure which on translational repetition, in the 3d gives the crystal structure
