2. Power Macintosh G3 - Wikipedia

   en.wikipedia.org/wiki/Power_Macintosh_G3

   The G3 AIO was available in two basic configurations, a 233 MHz version with a floppy drive and a 4 GB hard drive, and a 266 MHz version with a built-in Zip drive, floppy drive, and either a "Whisper" personality card or an All-In-One version of the "Wings" personality card. It was the last Macintosh to ship with an internal floppy disk drive.

3. RAM drive - Wikipedia

   en.wikipedia.org/wiki/RAM_drive

   RAM drives use normal system memory as if it were a partition on a physical hard drive rather than accessing the data bus normally used for secondary storage. Though RAM drives can often be supported directly in the operating system via special mechanisms in the OS kernel, it is generally simpler to access a RAM drive through a virtual device ...

4. iMac G4 - Wikipedia

   en.wikipedia.org/wiki/IMac_G4

   The iMac G4 [a] is an all-in-one personal computer designed, manufactured, and sold by Apple Computer from January 2002 to August 2004. The computer is comprised of a hemispheric base that holds the computer components, including the PowerPC G4 processor, with a flatscreen liquid-crystal display (LCD) mounted above.

5. iMac G3 - Wikipedia

   en.wikipedia.org/wiki/IMac_G3

   The iMac has no serial ports, Apple Desktop Bus, or floppy disk drive. To replace the removed ports, the iMac has Universal Serial Bus (USB) ports, which were faster and cheaper than Apple Desktop Bus and serial ports but were very new—the standard was not finalized until after the iMac's release—and unsupported by any third-party Mac ...

6. Hibernation (computing) - Wikipedia

   en.wikipedia.org/wiki/Hibernation_(computing)

   Hibernation (also known as suspend to disk, or Safe Sleep on Macintosh computers [1]) in computing is powering down a computer while retaining its state. When hibernation begins, the computer saves the contents of its random access memory (RAM) to a hard disk or other non-volatile storage. When the computer is turned on the RAM is restored and ...

7. Nonvolatile BIOS memory - Wikipedia

   en.wikipedia.org/wiki/Nonvolatile_BIOS_memory

   Nonvolatile BIOS memory refers to a small memory on PC motherboards that is used to store BIOS settings. It is traditionally called CMOS RAM because it uses a volatile, low-power complementary metal–oxide–semiconductor (CMOS) SRAM (such as the Motorola MC146818 [1] or similar) powered by a small battery when system and standby power is off. [2]

8. Classic Mac OS memory management - Wikipedia

   en.wikipedia.org/wiki/Classic_Mac_OS_memory...

   The RAM limit in the Macintosh design was 4 MB of RAM and 4 MB of ROM with the remaining 8 MB addresses split between the SCC, IWM and VIA chips, because of the structure of the memory map. [ 9 ] [ 10 ] This was fixed by changing the memory map with the Macintosh II , allowing up to 8 MB of RAM, by shrinking ROM and I/O addresses to 1 MB each ...

9. Trim (computing) - Wikipedia

   en.wikipedia.org/wiki/Trim_(computing)

   Regardless of operating system, the drive can detect when the computer writes all zeros to a block, and de-allocate (trim) that block instead of recording the block of zeros. If reading a de-allocated block always returns zeros, this shortcut is transparent to the user, except for faster writing (and reading) of all-zero blocks, in addition to ...
