This document discusses different types of computer storage. It describes primary storage such as RAM, ROM, flash memory, and cache memory. RAM is volatile and loses data when power is removed, while ROM is non-volatile. Secondary storage, like hard disks, CDs, DVDs, USB drives, SSDs, provide permanent storage and are examples of "backing store" or "auxiliary storage." Tertiary storage uses removable media like tapes or optical discs in large quantities for archiving purposes.

2.  Refers to computer components and
recording media that retain digital data.
 Primary srorage
 Secondary storage
 Tertiary storage or Tertiary memory

3.  Four main types of primary storage
RAM (Random Access Memory)
ROM (Read Only Memory)
 Flash memory
 Cache memory

4.  Volatile type of memory that is constantly being written to and read
form.
 It does not retain its contents without a constant supply of power.
When a computer is turned off, everything stored in RAM is lost.

5.  A non-volatile memory or storage containing data that
can not be changed.

6.  Secondary storage is a memory that is stored external
to the computer. It is mainly used for the permanent
and long-term storage of programs and data.
 Hard Disk, CD, DVD, Pen/Flash drive, SSD, etc, are
examples of secondary storage.
 It is also known as BACKING STORE or AUXILIARY
STORAGE.

8.  HDDs are usually
installed inside desktop
computers, mobile
devices, consumer
electronics and
enterprise storage arrays
in data centers. They
can store operating
systems, software
programs and other files
using magnetic disks.

9.  A solid-state drive (SSD) is a
new generation of storage
device used in computers.
SSDs store data using flash-
based memory, which is much
faster than the traditional hard
disks they've come to replace.
SSDs also have no moving
parts, and upgrading to one is a
great way to speed up your
computer and make it more
resilient. Learn how SSDs work
and how to keep them
optimized with performance-
boosting software.

10.  A pen drive, or a USB flash drive,
is a portable data-storage device.
Pen drives have replaced the
floppy drives of old and have
become the most popular data-
storage devices among
consumers. Micro, lightweight
and handy, a pen drive can be
easily carried from place to place
by students, professionals,
academicians and independent
tech consultants.


11.  Tertiary storage comprises
high-capacity data archives
designed to incorporate
vast numbers of removable
media, such as tapes or
optical discs. The
removable media are
normally not stored in
suitable drives but held in
specially arranged
retention slots, shelves, or
carousels in an offline
state.
