The Raspberry Pi 4 is available with 1, 2, 4 or 8 GB of RAM. [99] A 1 GB model was originally available at launch in June 2019 but was discontinued in March 2020, [57] and the 8 GB model was introduced in May 2020. [100] The 1 GB model returned in October 2021. [58] The Raspberry Pi 5 is available with 2, 4, 8 or 16 GB of RAM. [101]
The Raspberry Pi 4 is the 4th generation of the mainline series of Raspberry Pi single-board computers.Developed by Raspberry Pi (Trading) Ltd [1] and released on 24 June 2019, the Pi 4 came with many improvements over its predecessor; the SoC was upgraded to the Broadcom BCM2711, two of the Raspberry Pi's four USB ports were upgraded to USB 3.0, and options were added for RAM capacities ...
The word nature of data transfer makes the design of a host bus adapter significantly simpler than that of the precursor HDD controller. CTL-I (Controller Interface) [3] was an 8-bit word serial interface introduced by IBM for its mainframe hard disk drives beginning with the 3333 in 1972. [4]

The M.2 standard allows module widths of 12, 16, 22 and 30 mm, and lengths of 16, 26, 30, 38, 42, 60, 80 and 110 mm. Initial line-up of the commercially available M.2 expansion cards is 22 mm wide, with varying lengths of 30, 42, 60, 80 and 110 mm. [3] [5] [14] [18] The codes for the M.2 module sizes contain both the width and length of a ...
Enhanced Small Disk Interface (ESDI) is a hard disk drive interface designed by Maxtor Corporation in 1983 to be a follow-on to the ST-412/506 interface. [1] ESDI improved on ST-506 by moving certain parts that were traditionally kept on the controller (such as the data separator) into the drives themselves, and also generalizing the control bus such that more kinds of devices (such as ...
Raspberry Pi OS is a Unix-like operating system based on the Debian Linux distribution for the Raspberry Pi family of compact single-board computers. Raspbian was developed independently in 2012, became the primary operating system for these boards since 2013, was originally optimized for the Raspberry Pi 1 and distributed by the Raspberry Pi Foundation.
