The 2 main types of timber are Softwoods and Hardwoods.
The two main types of rocket engines are Solid fuel rocket engines and Liquid fuel rocket engines.
ROM (Read only Memory) and RAM (Random access memory). However, there are loads more types of computer memory than these two.
the two basic types of diseases are viral and bacterial
There are two main categories of variables in Java. They are primitive and non primitive. Primitive data types are the basic data types like int, float, char etc. These are not objects. The other non primitive data types are all types of Java Objects. Example: String, ArrayList etc.
Biologists use two main types of electron microscopes. Transmission electron microscopes (TEMs) shine a beam of electrons through a thin specimen. Scanning electron microscopes (SEMs) scan a narrow beam of electrons back and forth across the surface of a specimen.
Two types of electron microscopes are the scanning electron microscope, or SEM, and transmission electron microscope, or TEM.

Electron microscopes use beams of electrons to produce magnified images. There are two main types: transmission electron microscopes (TEM) and scanning electron microscopes (SEM). They are capable of achieving much higher magnifications and resolutions compared to light microscopes.

An optical, and an electron microscope.
Two types of microscopes that view the surface of an object are stereo microscopes, which provide a three-dimensional view, and scanning electron microscopes (SEM), which provide high-resolution images by scanning the surface with a focused beam of electrons.
There are a variety of microscope types, but two large and different types are electron microscopes and optical microscopes. Optical microscopes are cheaper, and are commercially available for even you to buy. They work with lenses, and in many cases, oil emulsions. Electron microscopes work by bombarding specimens with electron beams. They are significantly more expensive than optical microscopes, but give a better quality image and come with vastly superior magnification levels, due to the fact that electrons have wavelengths circa 100,000 shorter than photons, or light. This enables you to see things in much greater detail.
The two types of microscopes that can view objects that have been sliced and treated to improve contrast are the light microscope and the electron microscope. Light microscopes use visible light to illuminate samples, while electron microscopes use a beam of electrons for imaging. Both types can reveal detailed internal structures of specimens through contrast enhancement techniques.
