Cloud computing is an application-based software infrastructure that stores data on remote servers, which can be accessed through the internet. To understand how cloud computing works, it can be divided into front-end and backend.
The front-end enables a user to access data stored in the cloud using an internet browser or a cloud computing software. However, the primary component of cloud computing – responsible for securely storing data and information – is the backend. It comprises servers, computers, databases, and central servers.
The central server facilitates operations by following a set of rules known as protocols. It uses a software, middleware, to ensure seamless connectivity between devices/computers linked via cloud computing. Cloud computing service providers usually maintain multiple copies of the data to mitigate instances of security threats, data loss, data breach, etc.

O circuito resistivo da figura abaixo pode ser simplificado.

A tensão e a resistência totais deste circuito são, respectivamente:
Os resistores fixos feitos de carbono podem ser facilmente identificados pelos técnicos. Ao organizar os componentes de um laboratório, o funcionário encontrou os resistores com a seguinte sequência de cores:
2º resistor: laranja, laranja, laranja e dourada;
3º resistor: vermelho, violeta, marrom e dourada.
Estes resistores são, respectivamente:
A figura ilustra um retificador de onda completa em ponte.

Considerando os diodos ideais e a relação de transformação 10:1, ao calcular a tensão média na carga o técnico de eletrônica encontrará:
Para regular uma tensão já retificada e filtrada, pode-se utilizar um circuito regulador que é composto basicamente por um diodo zener associado em paralelo à carga.

Tendo Vz = 5 V, Izₘₐₓ = 100 mA e Izₘᵢₙ = 10 mA, a resistência mínima (Rsmin) de regulação para o circuito mostrado na figura é:
A figura mostra um diagrama esquemático que representa um transistor controlado por tensão.
