3. What’s the difference between RAM and
ROM?
Jawaban :
RAM (random access memory)
chips temporarily hold
(1) software
instructions and (2) data
before and after it is processed by the CPU.
Think of RAM as the primary
workspace inside your computer. When you
open a file, a copy of the file
transfers from the hard disk to RAM, and this
copy in RAM is the one that
changes as you work with the file. When you
activate the Save command, the
changed copy transfers from RAM back to
permanent storage on the hard drive.
Because its contents are
temporary, RAM is said to be volatile
—the contents
are
lost when the power goes off or is turned off. This is why you
should frequently —every
5–10 minutes, say—transfer (save) your work to a
secondary storage medium such
as your hard disk, in case the electricity goes
off while you’re working.
(However, there is one kind of RAM, called flash
RAM, that is
not temporary, as we’ll discuss shortly.)
ROM CHIPS—TO STORE FIXED
START-UP INSTRUCTIONS Unlike RAM,
to which data is constantly
being added and removed, ROM (read-only
memory) cannot be written
on or erased by the computer user without
special equipment. ROM chips
contain fixed start-up instructions.
That is, ROM chips are loaded,
at the factory, with programs containing
special instructions for basic
computer operations, such as those that start the
computer (BIOS) or put
characters on the screen. These chips are nonvolatile;
their contents are not lost when power to the
computer is turned off.
ROM kependekan dari read only memory, yaitu
perangkat keras pada komputer berupa chip memori semikontuktor yang isinya
hanya dapat dibaca. ROM ridak dapat digolongkan sebagai RAM, walau pun keduanya
memiliki kesamaan yaitu dapat mengakses secara acak( random). ROM berbeda
dengan RAM
