I'll Tell You What Firmware is. Firmware is: Software, Defined Hardware. Some Chips: E.g. A Sound Card - The Decoding Can Be Done with Specialised Transistors (Gates) - VHDL/Verilog. Such a Card, Will NOT Need: Firmware. The Same Sound Card, Can be Made with a General Purpose ARM CPU and a DAC (Digital to Analogue) Converter. The Manufacturer, Then Might Allow The Updating of The ARM CPU Flash Memory, that Does the Sound Decoding. That Will Be Called Firmware. The BIOS is The First Piece of Code The The CPU Executes. The CPU Does NOT Know How to Read The Hard Disk. The CPU, Only Know How to Read Memory, Upon Booting Up. The BIOS Flash Memory can be Updated - To Allow the Reading of Various NEW Hard Disks. This is Called Firmware for Two Reasons. 1: The Firmware, Does Not sit on The Hard Disk. 2: The BIOS Firmware - Controls the Functionality of The - First Memory Chip, Accessed by The CPU. The BIOS Memory Chip, Boots Up the Computer. Even, with NO HARD Disk - The BIOS Memory Chip - Can Display Diagnostics, System Information to The User. Its a Chip that The CPU chip, First Accesses. Its a Memory Chip That Boots Up the Computer. Its Functionality can be Updated, if Allowed by The Manufacturer - By Using Firmware.
I wasn’t expecting for it to be this informative. Good job ! Covered important key points that made a big difference.
Great video! thanks for taking the time to make this!
Excellent video, a massive thank you to this outstanding job!!!!
So informative
Super very useful to me😊🎉
impressive
❤❤🎉🎉 so good
Very informative
So u mean firmware is the process of a waiter with restaurant and customer,where as software is process between chef,owner and business
i cant understand your English
U don't know English
I'll Tell You What Firmware is.
Firmware is: Software, Defined Hardware.
Some Chips: E.g. A Sound Card - The Decoding Can Be Done with Specialised Transistors (Gates) - VHDL/Verilog.
Such a Card, Will NOT Need: Firmware.
The Same Sound Card, Can be Made with a General Purpose ARM CPU and a DAC (Digital to Analogue) Converter.
The Manufacturer, Then Might Allow The Updating of The ARM CPU Flash Memory, that Does the Sound Decoding. That Will Be Called Firmware.
The BIOS is The First Piece of Code The The CPU Executes. The CPU Does NOT Know How to Read The Hard Disk.
The CPU, Only Know How to Read Memory, Upon Booting Up.
The BIOS Flash Memory can be Updated - To Allow the Reading of Various NEW Hard Disks. This is Called Firmware for Two Reasons.
1: The Firmware, Does Not sit on The Hard Disk.
2: The BIOS Firmware - Controls the Functionality of The - First Memory Chip, Accessed by The CPU.
The BIOS Memory Chip, Boots Up the Computer.
Even, with NO HARD Disk - The BIOS Memory Chip - Can Display Diagnostics, System Information to The User.
Its a Chip that The CPU chip, First Accesses.
Its a Memory Chip That Boots Up the Computer.
Its Functionality can be Updated, if Allowed by The Manufacturer - By Using Firmware.
Some BIOS's Cant Be Updated with Firmware. Hard Coded Gates/Transistors (ROM) - Boots Up the System. Some Bios's Dont Have Firmware.
I Dont Think 1990's BIOS's Could be Updated with Firmware. It Was ALL ROM. No Firmware.
