New USB 3.0


New SuperSpeed USB 3.0 Finally arrives.The beauty of USB 3.0 is its backward compatibility with USB 2.0; you need a new cable and new host adapter motherboard that supports USB 3.0, but you can still use the device on a USB 2.0 port and achieve typical USB 2.0 performance. In reducing some overhead requirements of USB (now, the interface only transmits data to the link and device that need it, so devices can go into low power state when not needed), the new incarnation now uses one-third the power of USB 2.0.
The theoretical throughput improvement offered by USB 3.0 is dramatic -- a theoretical 10X jump over existing USB 2.0 hardware. USB 2.0 maxed out at a theoretical 480Mbps, while USB 3.0 can theoretically handle up to 5Gbps. Mind you, applications like storage will still be limited by the type of drive inside; so, for example, you can expect better performance from RAIDed hard drives or fast solid-state drives (SSDs) than from, say, a standalone single drive connected to the computer via USB 3.0.
USB 3.0 performance was on a par with eSATA but the benefit here is that it don’t need a power port, so you don't need to have another external power supply running to the drive

Dell New Device

It still not in the market yet. What is known about the device so far is that it has a 5 inch touch screen and a 5 megapixel camera with an LED flash. A SIM slot was also spotted, meaning it should have 3G data capabilities. Dell representatives were not divulging any more information on the hardware specifications. Likewise, pricing and availability information is also unknown.

The most interesting bit of information is that it will be running an Android operating system. This makes the Dell tablet the first portable tablet style device that isn't primarily a cell phone.

With the flexibility of an Android OS, this breed of tablet may become a competitor to the likes of the iPod Touch. With no hardware specifications yet known, it remains to be seen how it will stack up against the Apple iSlate. Not sure when it can be purchase in Malaysia...

HDMI cable guide

HDMI or High-Definition Multimedia Interface is an interface standard used for audio-visual equipments such as HDTVs or home theater systems. In just a few years it has become some sort of de facto standard for all HDTVs or other audio/video units. All latest DVD Players, Blu-Ray Player, Game consoles, PC and even laptops are having an HDMI Port built into them. They have some certain advantages such as ability to carry both high quality audio and video in a single cable in a digital format making those old analog cables obsolete. If you want to know anything about HDMI, read this guide to know everything you need to know about it.
(If your pc don't have HDMI port, just change the graphic card to latest one that have HDMI port.)


The History
The HDMI standard was founded by leading consumer electronics manufactures - Hitachi, Panasonic, Philips, Sony, Toshiba, Thomson and Silicone Image. Because of its HDCP (High-Bandwidth Digital Content Protection) compliance, which provides copyright protection, it is also fully supported by major motion picture producers like Fox, Warner Bros, and Disney, as well as by system operators like DirecTV and EchoStar.


Key Features of HDMI
•It can handle both video and audio in a single cable.
•Very easy to set up. Even a child can do it with ease.
•Capability to handle High Quality of 1080p Video and 7.1 channel Audio.
•Ready for future higher resolution videos such as 1440p.
•Fully backward compatible with technologies such as DVI with the use of adapters.


Can I get the same quality of HDMI using analog cables?
Yes, you can get almost same quality, but that would need far more cables. The HDMI cables can transfer eight channels of 24 bit 192 kHz uncompressed audio for 7.1 surround sound. To get the same experience, you need to have eight separate cables for the same quality. Using component videos you can get almost the same quality in video but you need to have three cables for that.

What about HDMI cable length?
There is no official limits of the cable length. The HDMI cables can be made very cheaply using thinner wires but those wires provide reliable connections upto 5m. Using good quality materials and thicker wires you can get cables as long as 20m which would be enough for all of us.

Is there any different version of HDMI cables?
Yes, there are different versions of cables with newer versions supporting newer features. Version 1.4 is the latest but you can get a version 1.3 cable which is currently used by most of the devices.


Benefits of HDMI
•Provides enormous bandwidth upto 10.2 GBps which is more than twice the bandwidth needed to transmit a 1080p signal such as from a Blu-Ray Player.
•It can protect the data from Piracy using the HDCP protocol. Basically the protocol uses a handshaking mechanism to ensure that the data is transmitted between two authentic devices.

Our Suggestions about HDMI Ports and Cables
•You need not buy an expensive HDMI cables as the cables itself can’t improve or deteriorate the picture quality of the digital signals. A cheap cable under Rm 50 would be sufficient. However, if you are using cables greater than 5m length you might need to buy a more pricey cable as cheaper long length cables tend to show link failures with ’sparklies’ or dropouts in pictures which is very irritating.
•Before buying an LCD TV, check that there is at least two HDMI ports in it because you may need to connect your DVD players and your game console to your TV at the same time. Having at least two ports will ensure that you don’t need to switch them constantly to make place for the other.

eSATA Port Guide

eSATA or External Serial ATA is now a common interface used to connect devices such as external hard drives to you computer. They have several advantages over the USB or FireWire or SCSI interfaces which is why they are finding their place in desktop computers as well as standard laptops these days. Here is a guide to help you understand the functioning and benefits of the eSATA Port.

Key Features and Benefits of eSATA
•Practical Data transfer rates are higher than the USB or FireWire Ports.
•Cheaper overall cost of ownership.
•It uses same protocol as the SATA which means you can use the SATA drives in eSATA with no or barely minimal modification.
•Some low-level drive features, such as S.M.A.R.T., may not operate through USB or FireWire bridging but will work with eSATA.
•Extra Layer of shielding ensures that there is no Electromagnetic Interference between devices
•The connectors are have a specified life of upto 5000 insertions and removals.
•More robust i.e. severe force is needed to break it.

USB or FireWire external Drives actually use a PATA or a SATA drive inside it and an external enclosure which includes a controller to translate the ATA or SATA protocol to USB or FireWire. This translation involves some delay and also an overhead for the translation which won’t be necessary if you use a eSATA interface with a SATA HDD within it.

The maximum cable length of eSATA cables is 2 meters & data transfer speeds are 150MBps or 300MBps depend on hard disk.

VGA Port Guide

A VGA Connector is the most common port on any computer. It connects any standard monitor to the CPU or you can use this port on your laptop to connect an external monitor. It is also commonly known as RGB Connector, D Sub 15, mini sub D15 and mini D15 as it consist of a total of 15 pins in three rows. If you don’t know anything about this connector read our guide to know everything that you should know.

Key Features
•It is the most common connector found on most computer monitors, video cards and also HDTVs.
•The connectors and associated cabling carry analog RGB HV video signals along with digital clock signal and data.
•Supports Plug and Play Monitor detection.
•Robust connection secured by screws.

The 15 different pins has functions as follows.
The (1,6), (2,7), (3,8) pairs are use to convey the video signals of Red, Green and Blue colors respectively. The pin 13 and pin 14 are used for Horizontal and Vertical Syncing. The 5 and 10 pins are used as ground and other pins are of less importance to us.

DVI Port Guide


DVI or Digital Visual Interface is an interface on your computer through which you can get very high quality display as it uses digital techniques compared to VGA Ports which uses analog system to transfer the display data. Using the DVI Ports, digital display devices such as LCD Monitors and LCD Projectors can display more accurate color tones and contrast levels.

Key Features
•It uses digital protocols which uses streams binary data about the illumination of each pixels.
•There is no possibility of any noise or brightness effects from adjacent pixels ensuring the sharpness of the images.
•No possibility to connect it in an incorrect position.
•It is partially compatible with HDMI in DVI-D Mode and VGA in DVI-A Mode.
•It also supports Display Data Channel or DDC and Extended Display Identification Data or EDID.

Apple Tablet


Apple may have turned its nose up at the netbook market, but that doesn’t mean it’s ignoring the void between its $400 iPod touch (32GB) and $1,000 MacBook. Piper Jaffray analyst Gene Munster believes Cupertino will launch a touchscreen tablet, priced in the $500 to $700 range, in the first half of 2010.



Rumors of an iPod-like tablet have been swirling for months, with some speculating that Apple is developing a large-screen iPod touch—say, a 7- to 9-inch touchscreen device—that would be large enough for HD movies and maybe a few desktop-style apps. Such a device would provide a better gaming experience than the iPod touch too.

But please don’t call it a netbook, a bargain-bin class of laptop that Apple execs have dissed as “junky.”

There’s no smoking gun in the latest report, but it does appear as though Apple is up to something. As reported by CNN, Munster’s sleuthing led him to conclude that an Apple tablet is only months away.

The signs include: Apple’s recent interest in chip designers, including the company’s acquisition of low-power chipmaker PA Semi a year ago; Apple’s efforts to add multi-touch features to its core products, including iPods, iPhones, and Macs; and the quintessentially Apple need to differentiate itself in an established market. (Think iPods, iPhones, Macs, etc.)

Admittedly, Munster’s evidence is pretty slim. But when combined with other reports, including one from the Chinese-language Commercial Times that says Taiwan-based Wintek will soon supply touch panels for an upcoming Apple subnote, an touchscreen tablet seems very possible.

One thing’s for sure: An Apple tablet, subnote, or whatever you want to call it, won’t copy the successful-if-unspectacular netbook formula of a shrunken laptop with a cramped keyboard and tiny screen.

There’s certainly a market for a portable media player larger than the iPod touch, iPhone, or other smart phones. But what would people pay for such a device? If Apple’s sweet spot is $700, the alleged tablet would need some fairly robust wireless communications and productivity tools too.

Apple would be foolish to ignore the growing netbook market, which is attracting more and more potential laptop buyers. Odds are, it won’t.
