News: T-Mobile's G1 Gets Visual Voice Mail, Opera Browser

Source: http://www.cio-today.com/

November 25, 2008 8:39AM

A visual voice-mail application from PhoneFusion and the Opera Mini 4.2 browser have become available for T-Mobile's G1 smartphone powered by Google's Android mobile operating system. The free Opera Mini browser runs faster than the beta and is also available for the Samsung Instinct and newer phones from Sony Ericsson and Nokia.

A new visual voice-mail application and the Opera Mini browser were made available Monday for T-Mobile's Android-based G1 smartphone. The Opera Mini 4.2 mobile browser, released as a beta earlier this month, is now out in a free final version. It includes a performance increase of up to 30 percent over the beta, thanks to a farm of U.S.-based servers that preprocess and compress Web requests. It also includes skins, syncing with notes, support for multiple languages, and other features.

Opera Software describes the browser as "the world's most popular mobile Web browser," with more than 20 million users. Other features include staying in touch with friends via Facebook, searching with Google, and secure online banking,

The browser is also available for the Samsung Instinct and newer Sony Ericsson and Nokia phones. It offers browsing of full Web pages, with the user being able to zoom into a page whose text has been formatted correctly for the small screen.

The Opera Mini browser is available from the Opera Software site, as well as the Android Market, a Google app store comparable to Apple's iPhone App Store. The Android Market is also offering the beta version of Fusion Voicemail Plus from Ft. Lauderdale, Fla.-based PhoneFusion.

Magnetic Tape

Magnetic tape is a non-volatile storage medium consisting of a magnetic coating on a thin plastic strip

It is used for video, audio storage, and general purpose digital data storage

Data is stored in frames across the width of the tape

Frames are grouped into blocks or records which are separated from other blocks by gaps

Magnetic tape is a serial access medium



Magnetic Tape



Floppy Disk

• Soft magnetic disk• Less expensive• Portable

Features:

• 8-inch• Designed and invented by IBM

• 5¼-inch• Storage capacity varies from 100K to 1.2MB

(megabytes) of data

• 3½-inch• Storage capacity varies from 400K to 1.4MB

Floppies come in three basic sizes:



Compact Disk

A Compact Disk (CD) is an optical disk to store digital data

It is made up of pure polycarbonate plastic disk

In a CD, data is stored as a series of tiny indentations (pits), encoded in a tightly packed spiral track of pits molded into the top of the polycarbonate layer

Infrared 780 nm laser is used to write data on a CD

Types of CDs:

• CD-ROM• CD-R/W



CD-ROM

Compact Disk Read-Only Memory

Each CD-ROM sector is 2352 bytes, and contains 2048 bytes of PC Data, 2336 bytes of PSX/VCD Data or 2352 bytes of AUDIO

A standard 120 mm CD-ROM holds 650 or 700 MB of data



DVD

DVD is also known as "Digital Versatile disk" or "Digital Video disk”

DVDs use a 650-nm-wavelength red laser

It has enough space to store a full-length, MPEG-2-encoded movie, as well as a lot of other information

Like a CD, the data on a DVD is encoded in the form of small pits and bumps on the track of the disk

• Higher-density data storage• Less overhead, more area• Multi-layer storage

DVDs can store more data than CDs because of:



DVD

Data Tracks on a DVD DVD-R Read/Write Side



DVD-R, DVD+R, and DVD+R(W)

• DVD-R is a DVD recordable format• It has storage capacity of 4.7 GB

DVD-R:

• A DVD+R is a writable optical disk with 4.7 GB of storage capacity

• DVD+R disks can be written only once

DVD+R:

DVD+R(W) has a more robust error management system than DVD-R(W)



DVD-RW, DVD+RW

• A DVD-RW is a rewritable optical disk with storage capacity equal to a DVD-R, typically 4.7 GB

• The primary advantage of DVD-RW over DVD-R is the ability to erase and rewrite on a DVD-RW disk

DVD-RW:

• A DVD+RW is a rewritable optical disk with storage capacity equal to a DVD+R, typically 4.7 GB

DVD+RW:

Both disks are used for volatile data storage such as backups



DVD+R DL/ DVD-R DL/ DVD-RAM

• DVD+R DL is a dual layer writeable DVD+R• DVD-9:

• The dual layered disks can hold 7.95 GB data

• DVD-18:• The dual layered double sides disks can hold 15.9 GB data

DVD+R DL:

• DVD-R DL or DVD-R9 is a dual layer writeable DVD-R

DVD-R DL:

• DVD-RAM has the best recording features but it is not compatible with most DVD-ROM drives and DVD-Video players

• It is usually used in some DVD Recorders

DVD-RAM:



Blu-Ray

Blu-ray is the next-generation digital video disk patented by SONY

With their high storage capacity, Blu-ray disks can hold and play back large quantities of high-definition video and audio, photos, and other digital content

Blu-Ray disks use 405 nanometer blue-violet lasers

A single-layer Blu-ray disk can hold up to 27 GB of data and a double-layer Blu-ray disk can store up to 50 GB of data



Blu-Ray (cont’d)

• Records high-definition television (HDTV) without any loss in quality

• Instantly skips to any spot on the disk• Records one program while watching another on the

disk • Creates playlists• Edits or reorders programs recorded on the disk• Automatically searches for an empty space on the

disk to avoid recording over a program• Accesses the web to download subtitles and other

extra features

Advantages:




Network Attached Storage (NAS) is a dedicated hard disk-based storage technology

It is designed to be connected directly to a computer network, providing centralized data access to multiple network clients

A single hardware device, called the NAS box or NAS head, acts as the interface between the NAS and network clients



iPod

The iPod is a brand of portable media players designed and marketed by Apple Computer

The full-sized model stores media on a built-in hard drive, while the smaller iPod nano and iPod shuffle uses flash memory

Secure Digital Input Output (SDIO) (cont’d)



Compact Flash (CF) Memory Card

CF Card also called CF memory card is a small removable mass storage device

Compact Flash cards contain memory chips and a controller

CF cards with storage capacity of more than 2GB use the FAT32 file system

There are two types of Compact Flash cards: Type I (3.3mm thick) and Type II (5mm thick)

CF memory Cards are designed with flash technology, a non-volatile storage solution that does not require a battery to retain data indefinitely

These are faster and more reliable and consume only five percent of the power required by small disk drives

Electronic circuitry is built using semiconductors

Advantage of SSD over magnetic hard drives are:

• Less power usage• Faster data access• Higher reliability




The most common approach to ease the burden of backup and restoring of data is the tape library or autoloader

Autoloaders are the data storage devices with at least one tape drive

Larger autoloaders with multiple drives are known as tape libraries

A tape library is one or more tape backup drives in an enclosure that contains a robotic mechanism for changing tapes

Tape libraries are commonly used for centralized backup and restore

Hybrid hard drive is a hard disk drive that also contains flash memory

It offers several advantages compared to conventional HDDs

The power consumption of the hybrid hard drive is less than that of the hard disk drive

It allows computers to boot quickly

It gives longer life expectancy due to the reduction in time in operating motor and electronic components



Benefits of Hybrid Hard Drive



Holographic Data Storage

Holographic memory allows high record density together with maximum data access speed

It is achieved due to the holographic image (hologram) coded in one big data block which is recorded at one access

The device first splits a blue argon laser beam into separate reference and object beams

The object beam that carries the information gets expanded so that it fully illuminates a spatial light modulator (SLM)

To read the stored data, the hologram is illuminated with the reference beam
