Static Testing, a software testing technique in which the software is tested without executing the code. This Techniques provide a powerful way to improve the quality and productivity of software development by assisting engineers to recognize and fix their own defects early in the software development process.

It has two parts as listed below:

Review - Typically used to find and eliminate errors or ambiguities in documents such as requirements, design, test cases, etc.

Static analysis - The code written by developers are analysed (usually by tools) for structural defects that may lead to defects.

In this software is tested without executing the code by doing Review, Walk Through, Inspection or Analysis etc.

Hence, Error guessing is not a static software testing technique.

The two major types of computer chips are Microprocessor and Primary memory chips.

An amorphous or non-crystalline solid is a solid that lacks the long-range order that is characteristic of a crystal. In Brief, An amorphous solid is any noncrystalline solid in which the atoms and molecules are not organized in a definite lattice pattern. Such solids include glass, plastic, and gel.

Quartz glass (SiO2) is an amorphous solid due to its short range order of constituent particles. Note Quartz is a crystalline solid while quartz glass is an amorphous solid.
