San Francisco in 1956, IBM was the first company to develop and sell the first commercial Hard Disk Drive (HDD). Typically read-write speeds are limited to its bandwidth or have mechanical limitations of either rotation speeds and arm movement delays for storage types such as Cloud Storage, Hard Disk Drive or CD-RWs, DVD-RWs, SD cards, Solid State Drive, SRAM, and DRAM, or other integrated circuitry. This means that you can write data to it, and that information will persist even in the absence of a power source. Non-volatile memory is considered static, or storage-type memory. Volatile memory is usually in the form of a microchip or other hardware that requires an external power source to enable data to persist. In the below example, we are creating a file using the writeFile() method and reading the content of the file readFile() method.Read–write memory is composed of either volatile or non-volatile types of storage.

err: If the process fails, this is the error that will be thrown.

callback: This function gets invoked when the method is run.

It includes three more parameters that may be selected.

options: It’s a string or object that may be used to indicate optional output options.data: The data that will be sent to the file is a string, Buffer, TypedArray, or DataView.When you use a file descriptor, it will function similarly to the fs. file_name: It’s a string, a buffer, a URL, or a file description integer that specifies the location of the file to be written.Syntax: fs.writeFile( file_name, data, options, callback ) If the file already exists, it will be replaced. The fs.writeFile() function is used to write data to a file in an asynchronous manner. Return Value: It returns the contents contained in the file, as well as any errors that may have occurred.callback function: This is a function that is invoked after the file has been read.encoding: It stores the file’s encoding.filename: It contains the filename to be read, or the whole path if the file is saved elsewhere.
