These small devices are essentially used to transfer liquids from one dish to another. In this piece we will take a closer look at some of the different types of pipettes often used in laboratories around the world.
A frontage road is a local road running parallel to a higher-speed, limited-access road. A frontage road is often used to provide access to private driveways, shops, houses, industries or farms. Where parallel high-speed roads are provided as part of a major highway, these are also known as local-express lanes. A frontage lane is a paved path that is used for the transportation and travel from one street to another. Frontage lanes, closely related to a frontage road, are common in metropolitan a
In software engineering, front end (frontend) and back end (backend) distinguish between the separation of concerns between the presentation layer (the front end) â which is the interface between the user â and the data access layer (the back end).

Each can be spoken of as having a front end and a back end. The front is an abstraction, simplifying the underlying component by providing a user-friendly interface.
