Ever since Samsung introduced itself to the world in 1969 it has gone on to become one of the largest electronic companies in the world, thanks to its efforts to deliver cutting edge and innovative technology. Now Samsung has come up with a new species of HD TV’s-the LED TV which is said to be the GOD FATHER of next generation HD TV technology. LED TV’s have been dubbed to be the future for wide screen televisions and Samsung leads the way with their energy saving features, stunning designs and immaculate performance.

They have come up with 4 different models and they are:

7 series:

46” – UA46B7000

40” - UA40B7000

6 Series:

46” – UA46B6000

40” - UA40B6000

The new technology has already received the prestigious “Innovation Award” from the EISA (European Image and Sound Association) for its superb features which include:

A. Actual Width of the LED TV is 2.99 cm . The use of LED technology enables Samsung’s LEDTVs   to be unbeleivable 70 percent slimmer than the conventional one. Samsung has also reduced the gap between the TV and the wall to around 15mm, where earlier all flat screen models had a gap of 2 inches from the wall. By reducing this space, the Samsung LED TVs truly look like a picture frame hanging on a wall.

B. The depth is the first most noticeable feature which comes up with a state of art crystal design. Samsung’s Series 6 and 7 being only 1.2″ thin are being made from one single part rather than multiple parts being built together.

C. To deliver stunning and picture perfect colours Samsung has come up with certain features such as Mega Contrast Ratio to enhance greys to give authentic blacks for brighter images, a Wide Colour Enhancer Pro with LED Gamut and 100Hz Motion Plus technology which will deliver extreme detail, vibrancy and colour.

D. Above all this beautiful masterpeice  is recyclable and environmentally friendly with a frame that contains no VOC’s (Volatile Organic Compounds), up to 40% lower power consumption and an ultra low power consuming standby mode.

E. Also includes a Samsung WS1* Sound Bar Surround System for realistic acoustics.

In addition to above all features Series 7 of this LED TV comes up with a pebble shaped remote control which separates the series, with series 7 being the first to adopt such an attractive and comfortable remote.

FINAL VERDICT:

To be frank I am speechless when I visualize its slimness. It is needless to say that the color and picture of images are simply stunning.So absolute beauty. 5/5

A bad sector is a sector on a computer’s disk drive that cannot be used due to permanent damage, such as physical damage to the disk particles. It is usually detected by a disk utility software such as CHKDSK or SCANDISK on Microsoft systems, or badblocks on Unix-like systems. When found, these programs mark the sectors unusable and the operating system skips them in the future.

Hard drives usually have several platters. The platters are the discs which are covered with magnetic material which is used to hold data. Floppy disk drives contain only one platter.Platters are divided into a set of concentric rings called tracks. A 1.44MB floppy disk has 160 tracks. Hard drives have thousands of tracks.Each of these tracks is divided into smaller storage areas called sectors. A sector is the smallest storage area on a disk.

A modern hard drive comes with many spare sectors. When a sector is found to be bad by the firmware of a disk controller, the disk controller remaps the logical sector to a different physical sector. In the normal operation of a hard drive, the detection and remapping of bad sectors should take place in a manner transparent to the rest of the system. When the operating system begins to detect bad sectors, in most cases, it means that the surface of the hard disk is failing and the drive has run out of spare sectors with which to remap the failed sector. There are a variety of utilities that can read the SMART information to tell how many sectors have been reallocated, and how many spare sectors the drive may still have.

The minute your computer’s hard disk starts to act flaky, make sure you have an up-to-date backup. Then you can do some simple diagnostics and repairs. Both Windows and Mac OS come with built-in hard-disk utility software that scans your hard disk for errors and attempts to fix them.

Occasionally one or more sectors on an otherwise good hard drive will go bad.When this happens, the data in those sectors may be lost, but the data on the rest of the disk will be unaffected and the disk is still completely usable.Those bad sectors can not be repaired, but they can be marked as unusable. Once marked as unusable, the Operating System will know not to attempt to store data in those bad sectors. The total disk capacity will be decreased by the amount of storage space in those bad sectors.

If your hard drive is experiencing a bad sector, back it up immediately. If the bad sector was caused by a faulty drive head, the problem can spread to many other sectors across the disk.

For Windows

Anti virus software is probably the most important program you have installed on your computer, but do you really know how it works? Most PC owners purchase or install an anti virus program and forget about it. But if you don’t understand how anti virus software works, you might be leaving yourself prone to catching a virus.

Real-Time anti virus protection

Most anti virus programs use virus signature scanning to detect viruses on your computer. This means that the anti virus program has a list of known virus signatures in it’s database, and checks this database each time your PC opens or access any file. A virus signature is a particular pattern of ‘bits’ or information contained in a virus that appears in no other file or program in the world, except for that virus. A signature is like a digital fingerprint of the virus. A good anti virus program will have a database of approx 20,000 to 60,000 known viruses. Because it can take a few milliseconds to screen every file through a list of many thousands of virus signatures, it is common for an anti virus program to make your computer run a little slower after installation. One measure the effectiveness of an anti virus program is how much it does, or does not slow down a computer after installation.

On demand virus scanning

Another type of virus protection

is on demand scanning. Unlike real-time virus protection, on-demand only checks for viruses when manually initiated. Because you have no protection against a virus between on-demand virus scans, real time anti virus is a better method of protecting your PC against catching a virus, however a good antivirus program will support both methods of virus scan.

Anti virus protection is a constant game of keeping up

It is estimated that between 100 and 500 new viruses are released into the wild (spreading via the internet

) every day. Because of this constant influx new viruses, it is extremely important to update your anti virus program’s signature database as often as possible. Virtually all commercial anti-virus programs today will update themselves over the internet automatically every month, or more often. Good anti virus programs will even update themselves whenever a particularly dangerous virus is released onto the internet. Most free or low-cost anti virus programs require manual virus signature updates and are usually updated much less often than standard commercial anti virus programs. Because of the manual intervention required by many free anti virus programs, and the potential lack of signature updates, it is usually safer for your computer to purchase a good anti virus package. Even the best anti-virus programs rarely cost more than $49 - well worth the investment if you value your time, files, photos and other data in your PC.

Real-time and on-demand scanning are the best combination

Because real-time virus protection only protects your PC from virus threats since the last virus signature update, it is possible for a new virus to be released, get into your PC, and go totally unnoticed by your antivirus software. This is why even with a good antivirus program it is important to practice safe computing. To help catch any viruses that may have “slipped through the cracks” between virus signature database updates, it’s a good idea to run an on demand virus scan at least one time every month or two. Most commercial anti-virus programs will remind you to perform on-demand scans regularly, however many free or discount anti virus programs may not.
