play00:53

simplesmente pegou um software e colocou

play00:56

esse software dentro de si microchip

play00:58

durante o processo de fabricação

play01:01

isso é firmware quando o fabricante pega

play01:03

um software e coloca diretamente no

play01:05

hardware como por exemplo diretamente no

play01:08

microchip aí nós damos o nome disso de

play01:10

firmware é também aí um conceito

dois termos que estão ligados à software

play01:53

e hardware

play01:54

o termo drae ver o dry ver 100 r no

play01:57

final e o termo driver com r no final

com um pouco então a diferenciação de

play02:33

drive e drive é esse r 15 no final e

play02:36

percebe drae ver o hardware porque o

play02:39

dispositivo de armazenamento é o pen

play02:41

drive é o drive de cd é o drive de dvd é

play02:45

o antigo drive de disquete tão drive

play02:48

hardware palpável parte física e driver

play02:51

com r no final software programa de

play02:54

computador que permite ao windows ou a

play02:56

um sistema operacional controlar como um

play02:59

dispositivo de hardware funciona como eu

play03:01

disse antes o driver da impressora é o

play03:04

programa de computador que dispara o

play03:06

sistema operacional como aquela

play03:08

impressora funciona o driver do mouse é

play03:11

o programa de computador que dispara o

play03:13

sistema operacional como o mouse

play03:15

funciona essa ideia da diferenciação de
