Other Types of Storage

A magnetic stripe card contains a magnetic stripe that stores information
A smart card stores data on an integrated circuit embedded in the card

The RFID tag consists of an antenna and a memory chip that contains the information to be transmitted via radio waves

An RFID reader reads the radio signal and transfers the information to a computer or computing device

Microfilm and microfiche store microscopic images of documents on a roll or sheet film

Enterprise Storage

Enterprise hardware allows large organizations to manage and store data and information using devices intended for heavy use, maximum efficiency, and maximum availability
-RAID duplicates data, instructions, and information to improve data reliability

Network attached storage (NAS) is a server that is placed on a network with the sole purpose of providing storage to users, computers, and devices attached to the network

A storage area network (SAN) is a high-speed network with the sole purpose of providing storage to other attached servers

Tape is a magnetically coated ribbon of plastic capable of storing large amounts of data and information

A tape drive reads and writes data and information on a tape

Optical Discs

An optical disc consists of a flat, round, portable disc made of metal, plastic, and lacquer that is written and read by a laser

Optical discs commonly store items in a single track that spirals from the center of the disc to the edge of the disc

Track is divided into evenly sized sectors

A CD-ROM can be read  from but not written to

-Single-session disc

A CD-R is an optical disc on which users can write once, but not erase

A CD-RW is an erasable multisession disc 

A DVD-ROM is a high-capacity optical disc on which users can read but not write on or erase

A DVD-R or DVD+R are competing DVD-recordable WORM formats, on which users can write once but not erase

DVD-RW, DVD+RW, and DVD+RAM are high-capacity rewritable DVD formats

Cloud Storage

Cloud storage is an Internet service that provides storage to computer  or mobile device users

Here a quick explaination about Cloud Storage

Flash Memory Storage

Flash memory chips are a type of solid state media and contain no moving parts
An SSD (solid state drive) has several advantages over magnetic hard disks:

-Higher storage capacities

-Faster acces times

-Faster transfer rates

-Quieter operation

-More durable

-Lighter weight

-Less power consumption

-Less heat generation

-Longer life

A memory card is a removable flash memory device that you insert and remove from a slot in a computer, mobile device, or card reader/writer

Memory card examples are:

-CF

-SDHC

-SDXC

-miniSD

-microSD

-microSDHC

-microSDXC

-xD Picture Card

-Memory Stick PRO Duo

-M2

USB flash drives plug into a USB port on a computer or mobile device

Hard Disks Part 2

A head crash occurs when a read/write head touches the surface of a platter
Always keep a backup of your hard disk

Disk cache, sometimes called a buffer, consists of a memory chip(s) on a hard disk that stores frequently accessed data, instructions, and information

The larger the disk cache, the faster the hard disk

RAID (redundant array of independent disks) is a group of two or more integrated hard disks

An external hard disk is a separate freestanding storage device that connects with a cable to a USB port or other port on a computer or mobile device

....... getting a bit hard isn't it?

Hard Disks Part 1

A hard disk contains one or more inflexible, circular platters that use magnetic particles to store data, instructions, and information

Hard disks can store data using longitudinal recording or perpendicular recording

Formatting is the process of dividing the disk into tracks and sectors

Characteristics of a hard disk include:

-Tracks

-Sectors

-Platters

-Form factor

-Read/write head

-Revolutions per minute

Storage Part 2

Capacity is the number of bytes a storage medium can hold

Items on a storage medium remain intact even when you turn off a computer or mobile device

Access time measures:

The amount of time it takes a storage device to locate an item on a storage medium

The time required to deliver an item from memory to the processor

Storage Part 1

A storage medium is the physical material on which a computer keeps data, information, programs, and application.
Cloud storage is another storage option, in which the actual online storage media used is transparent to the user.
A storage device is the hardware that records and/or retrieves items to and from storage media.

Reading is the process of transferring items from a storage medium into memory.

Writing is the process of transferring items from memory to a storage medium.

.....pretty easy for starters....

Will post the first chapter soon guys.
