How a virus can spread through an E-Mail Message

Currently, more than 300,00 web sites can infect your computer with unknown virus, worms, trojan horse and other malware. These programs deliver to your computer with different ways of transfer:

1. open an infected file
2. runs an infected programs
3. plugged in a port
4. connected to the unprotected network

Normally, a common way on how computers may getting easily infected is by e-mail attachments. Here are some steps describing how a virus can spread through an e-mail message.

• Step 1 - Programmers or creators create a virus that may harm computer through deleting all files. By doing so, they hide the virus in a word processing document and attach the document to an e-mail message.

• Step2 - They send the e-mail message to thousand of computer users around the world.

• Step3(A) - Some users feel their computer is affected because of opening that unrecognized e-mail message.

• Step3(B) - Other users see unrelated e-mail message. Instead they immediately delete the e-mail message and continue their work.
  

From my point of view, be make sure to check every e-mail message you received before proceed. Peoples who just simply clicks without observe the senders will easily get affected by thousand of virus. Follows some instructions or guideline, so you will getting away from virus trapped.

Wireless Headphone

Bluetooth headphone is very familiar right?

Ever hear about Wireless Headphone?

Do you know what it is?

How does it work?

Im new in this technology and i wondering it is the same technology with bluetooth???

Wireless headphones work has become very easy like music can be heard while doing some work also and even it can be attached with the mobile phone to speak even without managing the cell phone set.

Wireless headphones free you from being a prisoner to your television or stereo system by having to be so close. Most corded headphones only let you go so far, but without wires you are free to room the room and many models will let you go into others as well.

This type of headphone will work with televisions, MP3 players, computers, as they are communicated by an infrared or radio signal to a central base station. This means you are free to do what you want as no longer do you have to be attached to a certain area in your home. Let us look at other advantages and some models.

Wireless technology has been designed with the consumer in mind to work with most stereo products and even with video games. If you are a gamer than you will want to give wireless a try with your video game system. It makes it much more fun for you and your family. They will not ever have to tell you to turn the noise down again.


The one thing about this technology is they are constantly improving on it. A few years ago the distance that you could get away from the base unit was much smaller. Now they are to the point where it get further away every year it seems. Most units also have a variety of channels just in case you have an interference problem in your area. It is rare this happens, but it can.


WHY THEY MAKE U PUT OUR TRUST ON THEM????

•Wireless headphones also possesses high sensitivity features also.

•Use 4 AAA batteries (2 for transmitter & 2 for receiver)

•Wireless headphones also comprise of Dulcet Bass

•Beside these the wireless headphone comprises Transmitter Receiver with FM Radio

•Through the luminous cordless design and the lightweight Open Air wireless system of the wireless headphone starting from TV Audio to Computer Audio Converter Modern Headphone people can roam around the space and take pleasure in the music they love for hours.

•Wireless headphones also gets connected to any, VCR, TV, DSS, Computer, VCD, MP3 CD Player, DVD, or Stereo System through the equipment of supplied cord and plug adapter,

•Wireless headphones also includes two audio inputs that provides switch with no trouble between sources.

WHICH ONE IS YOUR PREFERENCE?? LOW COST OR HIGH COST??

The Logitech FreePulse Wireless headphones or Sony RF Wireless headphones?



if your have low budget u can purchase The Logitech FreePulse Wireless....

The Logitech FreePulse Wireless headphones are one of the best sets around and at a very affordable price which makes it a winner in my book. While most lower price headphones are not worth the money this set is. The best thing about these is you can use these as well as on the road besides at home. Serving a dual purpose is always something I’m looking at when I spend my money.

BUT...

You also can purchase SONY RF WIRElESS HEADPHONE....These are very comfortable to wear and if you had to wear them all day you still would not have a problem. These are also very adjustable and have good sound quality. They come with surround sound which is a nice touch and if you love surround sound than maybe this is the set for you. Overall does a very good job, but is more expensive than the FreePulse.

YOUR SECOND CHOICE FROM SONY....


The MDR-RF960RK wireless headphones and the best thing about this model is everything is simple to operate and setup. Where most models give you instructions upon instructions this one is easy to operate and with 150 feet range it means you can move around without fear of losing your signal.

These are also very comfortable so that makes leaving them on for prolonged use no problem at all. All in all not a bad model for the price especially if you want to try wireless headphones for the very first time.

People are starting to realize that they want something more and this is where wireless headphones come into play. We have less and less time which means a lot of times we must catch shows at odd hours. Not to disturb the kids and others in the home wireless headphones are the perfect solution. It is the wave of the future and will only get better from here. Grab a set now and see how they can give you peace and quiet from the outside world and the ability to still listen to your music and your favorite television shows.

Hackers? Crackers?

Before I write this post, I don't know what the interesting topic that I have to share with you.I open my book then I close back..I open again and again and I my eyes stop at one page. Yeah! Got it! Hackers and Crackers..:)

Lets check together what is a hacker and what is a crackers? The spelling 'hackers' and 'crackers' is not a same but the sound is quite similar. So, do you think hackers and crackers is a same meaning? Or same character? Some people think of these two groups as being the same, but is it true? Come to join me to know about this two groups in generally..

"Hackers"

• Are people who create or improve programs and share those programs with fellow hackers.
• Typically they are not criminals
• A person who is very skilled at computing in general
• Obtain advanced knowledge of operating system & programming languages
• constantly seek further knowledge, freely share what they have discovered and never ever intentionally damage data.
• Example: programmer, IT professional, computer science experts
  

"Crackers"

• Create & share programs designed to gain unauthorized access to computer systems
• Their motives are malicious and can be destructive and costly
• Typically they are criminals
• A person who has a higher than normal degree of technical competency, but who uses his knowledge for malicious ends.

For my view, 'hackers' are not criminal. Why? Because hackers who were just want to explore the whole system. They usually willing to share their knowledge and take hacking as some sort of personal challenge. Furthermore, they are usually very well trained, whether formally or self-taught, in several different types of computing platforms. While 'crackers' used in criminal sense. Why? Because crackers might employ malicious codes to steal the data and try to attack systems and security personnel try to stop them by creating better security protocols.

Under these two broad categories, you can easily make your conclusion about both groups. But for me, "HACKERS is a GOOD and CRACKERS is a BAD!! Lets think together! :)

See You Next Time!

DEAF PEOPLE NOW CAN COMMUNICATE

Do you ever concern about people who are disability? at once ever you think how they enjoy the technology? how the use technology to connect with people in the world? in my opinion each creates in the world deserve to enjoy every development in this world and they also have their right to be with the technology....





Today i want to share with all of you about the TELECOMMUNICATION DEVICE FOR THE DEAF (TDD), this communication has been built for deaf community so they also can be part of the technology...

This technology has been developed by James C. Marsters (1924-2009). he is a dentist and private airplane who become deaf as an infant because of scarlet fever.



A telecommunications device for the deaf (TDD) is an electronic device for text communication via a telephone line, used when one or more of the parties has hearing or speech difficulties. Other names include teletypewriter (TTY) (TTY is also a term used forteletypes in general), textphone (Common in Europe and the UK), and minicom (United Kingdom).

The typical TTY is a device about the size of a typewriter or laptop computer with a QWERTY keyboard and small screen that usesLEDs or an LCD screen to display typed text electronically. In addition, TTYs commonly have a small spool of paper on which text is also printed — old versions of the device had only a printer and no screen.




The text is transmitted live, via a telephone line, to a compatible device, i.e. one that uses a similar communication protocol. In certain countries there are systems in place so that a deaf person can communicate with a hearing person on an ordinary voice phone using a human relay operator. There are also "carry-over" services, enabling people who can hear but cannot speak ("hearing carry-over," a.k.a. "HCO"), or people who cannot hear but are able to speak ("voice carry-over," a.k.a. "VCO") to use the telephone.

Device

There are a number of pieces of additional equipment that can be coupled to telephones to improve their utility. For those with hearing difficulties the telephone ring and conversation sound level can be amplified or pitch adjusted, ambient noise can also be filtered.

The amplifier can be a simple addition or through an inductive coupler to interact with suitable hearing aids. The ring can also be supplemented with extension bells or a visual call indicator.

The Top 3 World's Worst Virus!

Computer viruses have become increasingly dangerous and quick-spreading in the last couple of years

• Here's a look at three of the most dangerous  viruses and worms of all time.

1. Love Hurts

• LoveLetter is the worm everyone learned to hate in spring 2000. The infection affected millions of computers and caused more damage than any other computer virus to date. The worm sent copies of itself via Microsoft Outlook's address book entries. The mail included an executable file attachment with the e-mail subject line, "ILOVEYOU." The worm had the ability to overwrite several types of files, including .gif and .jpg files. It modified the Internet Explorer start page and changed Registry keys. It also moved other files and hid MP3 files on affected systems. Visit Symantec's Security Response for instructions on how to remove LoveLetter.

2. Klez the Conquerer

• The Klez worm, which blends different virus traits, was first detected in October 2001. Klez distributes itself like a virus, but sometimes acts like a worm, other times like a Trojan horse. Klez isn't as destructive as other worms, but it is widespread, hard to exterminate--and still active. In fact, so far, no other virus has stayed in circulation quite like Klez. It spreads via open networks and e-mail--regardless of the e-mail program you use. Klez sometimes masquerades as a worm-removal tool. It may corrupt files and disable antivirus products. It pilfers data from a victim's e-mail address book, mixing and matching new senders and recipients for a new round of infection. 

3. Malevolent Melissa

• The Melissa virus swamped corporate networks with a tidal wave of e-mail messages in March 1999. Through Microsoft Outlook, when a user opened an e-mail message containing an infected Word attachment, the virus was sent to the first 50 names in the user's address book. The e-mail fooled many recipients because it bore the name of someone the recipient knew and referred to a document they had allegedly requested.
•  The Melissa virus was the first virus capable of hopping from one machine to another on its own. And it's another good example of a virus with multiple variants. 

As conclusion, we have discussed about the top 3 virus,now, we shall now look at how to stay protected from them. REMEMBER!! you should not that remote tech support is very effective for eliminate virus in your PC.The engineers use the remote technical support technology to remove the virus from your PC

Each virus have their own alternative  to eliminate then form your PC.Its only depend on how you solve the PC problems that related to the virus! Or in a easy way, just installed the original antivirus as told by MADAM SHARIN in the previous class, so that the PC is reliable and safe from any dangerous virus! BEWARE!

World's Smallest 64GB Solid State Disk!

A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data. SSD are distinguished from traditional hard disk drives (HDDs), which are electromechanical devices containing spinning disks and movable read/write heads.

As of 2010, most SSDs use NAND-based flash memory, which retains memory even without power. SSDs is using volatile random-access memory (RAM) also exist for situations which require even faster access, but do not necessarily need data persistance after power loss, or use external power or batteries to maintain the data after power is removed.

A Hybrid Drive= HDD+SDD. In May 2010, Seagate launched the Momentus XT solid state hybrid drive. The SSD portion of new drive is also now a larger 4 GB, compared to 256 MB in th epast.


Compare to traditional HDDs, SSDs are typically less susceptible to physical shock, quiter, and have lower access time and latency. SSDs use the same interface as hard disk drives, thus easily replacing them in kosr applications.

NAND Flash uses floating-gate transistors, but they are connected in a way that resembles a NAND gate. These group are then connected via some additional transistors to a NOR-style bit line array. NAND flash uses tunnel injection for writing and tunnel release for erasing. NAND flash, memory forms the core of the removable USB storage devices known as USB flash drives, as well as most memory card formats and solid-state drives available today.


See you soon!
