TV is one of an integral part of homes in the modern world and it is essential equipment at night. And TV was one thing that impacted to change the human being’s living pattern. And it can be known as the basic equipment of communication also. Today, you can see various televisions are coming to the market with various technology and in various scales. When we look into the history of this television, it goes to 1800s. This was the result of numerous people’s efforts.

History of TV

In 1800s, a German student called Paul Gottlieb Nipkow developed the first ever mechanical module of television. He was able to send images through wires with the help of a rotating metal disk. In 1907, A.A. Campbell-Swinton from England and Russian scientist Boris Rosing, used the cathode ray tube to the television system in addition to this mechanical scanner system. As the result of two scientists, Nipkow and Rosing’s efforts, there was a platform to the mechanical television and electronic television. In 1923, the first practical mechanical television system was invented by an American inventor called Charles Jenkins used the disk idea of Nipkow. In 1926, the first tv with transmitting moving pictures was invented by John Logie Baird, through the mechanical disk system started by Nipkow. And in 1934, all television systems had converted into the electronic system. The television, what is being used in today is belong to this electronic system. Firstly, the black and white television was invented. And in 1970, it was able to invent the coloured television.

If you are computer user, you already made aware about the virus. This virus not only infects to your computer or mobile phone, but also it can damage to your server also. Actually they are developed to harm the computer by damaging programs, deleting files, or reformatting the hard drive. Therefore, in order to defeat this threat, there are virus guards created. Even you know about the virus, did you know the date this threat begin? Did you know the person who create this? Well, let’s look into the history of this…

The History of Virus

1949 – 1966 – Self-Reproducing Automata: In 1949, the “Self-replicating programs” were established and there were a large number of viruses produced by that. In 1966, John von Neumann, whose well-known to be the “Father of Cybernetics”, wrote an article of the “Theory of Self-Reproducing Automata”.

1971 – The Creeper; A self-replicating program was developed by Bob Thomas in 1971. And He entered into the ARPANET (The Advanced Research Projects Agency Network) and copied to a remote host systems with TENEX operating system. He copied self-replicating program. And then he kept a message as “I’m the creeper, catch me if you can!”.

1974 – Wabbit (Rabbit): It was the year that the infectious program was developed. And it made multiple copies of itself on a computer. It was clogging the system and reducing the performance of the computer.

1974 – 1975 – ANIMAL: For the UNIVAC 1108, John Walker developed a programme called ANIMAL. And this was known as a non-malicious Trojan also.

1981- Elk Cloner: For the Apple II Systems, Richard Skrenta developed a program called the “Elk Cloner”. And it started to spread through floppy disk.

1983 – Frederick Cohen coined the term computer VIRUS as the first time.

1986 – Brain: Two Pakistani programmers Basit Farooq Alvi, and his Amjad Farooq Alvi developed a virus called “Brain boot sector” for the IBM PC.

1987- Lehigh: IN order to infect files from Yale University, this virus was programmed.

Cascade: This is a self-encrypted file virus. And it was a result of IBM’s own antivirus product.

Jerusalem Virus: This virus was firstly detected the city of Jerusalem. To destroy all files in an infected computers on the thirteenth day, it was produced.

1990 – As the first time, Norton Antivirus Company launched this antivirus program which was called Symantec.

1995 – Concept: This was developed with targeting Microsoft Word documents.

1999 – Happy99: This virus targeted the emails which are mentioned with Happy New Year. The internet Explorer included Outlook Express and Windows 95/98, was attacked by that.

2000 – ILOVEYOU: This was able to delete the JPEGs, MP2 or MP3 files in the computer.

2001 – Anna Kournikova: This was spread via the emails, with an image of popular female tennis player.

2002 – LFM-926: This was developed by targeting Shockware Flash files.

Beast or RAT: This was known as backdoor Trojan horse. It was developed by targeting Windows OS. And it was highly spread.

2004 – MyDoom: This was spread through file and it was helpful to hackers to hack the computers.

2006 – OSX/Leap-A: This was the first virus which was produced to attack Mac OS.

Nyxem: This spread via mass-mailing. And it was capable to delete Microsoft Office files.

2007 – Storm Worm: This was a fast spreading email spamming threat. And it was able to attack millions of systems.

Zeus: This was one type of Trojan. And this was used to steal the login details of bank accounts.

2008 – Koobface: This was aimed to attack Facebook and MySpace.

2013 – Cryptolocker: This is also one type of Trojan. And it was infected machine and to unlock files.

2014 – Backoff: This was developed to attack the Point-of-Sale (POS) systems.

See, what a big history that virus has! And this will not be ended by here. The guys who are developing virus, are trying to attack to machines, files and many equipment and privacy information. So, best thing that we can do is install an antivirus to our computers/laptops and mobile phones.Virus


The people who use internet are looking for various methods to get the internet connection. Wire connection, Dongle, Mobile Date and Wifi are main methods of it. If few people want to connect to the internet at the same time, wifi is the best mode for that. As this technology spread speedily around the world, it has started to be popular among Sri Lankans also.  Even though many internet users are using this wifi, some of them are not knowing the meaning of wifi and its work.

What is this wifi?

A Wifi is the connection which is using a wireless adapter to create hotspots – areas in the vicinity of a wireless router. And they are connected to the network and allow users to access internet services at the same time. This connection is to limited define area and those who are in that area can access the internet via computers or mobile phones. When someone get this connection, he/she will have a password to access this facility. By that, that persn can control it. And the real meaning of this is Wireless Fidelity.

How did this Wifi begin? 

In 1985, the FCC (Federal Communications Commission) and the America’s Telecoms Regulator released some wireless spectrums to use, without a government license. These were known as “garbage bands” and it included: 900MHz, 2.4GHz and 5.8GHz radiofrequencies. At the beginning, this was allocated to non-communication purposes like microwave ovens and to military work in addition to communication. This technology developed day by day and during the period of 1997 – 2000, a committee, made up of engineers from NCR Corporation, Bell Labs, and IEEE agreed on an industrywide wireless standard. That was a data¬transfer rate of two megabits per second, using either of two spread¬spectrum technologies, frequency hopping or direct sequence transmission. Along that, the usage of 802.11a and 802.11b, (Max 11 Mbps) are started. In 1999, “IEEE 802.11b Direct Sequence” is retitled as “Wi-Fi”. And Lucent developed a wifi adapter for a less cost as $100. Along that, Apple Company launched the iBook with wifi, under the brand name called AirPort. During the period of 2003 – 2007, 802.11g 802.11e and 802.11n technologies were released. After having a such a long journey, wifi technology is having fast spread today.

Requirements to have wifi? 

  1. You should have a wireless transmitter (Wireless Access Point – WAP )
  2. It is needed to have a wifi adapter
  3. You should have a wifi network also. If you don’t have that, then you can inform it to ISPs (Internet Service Providers) and have a network.

What are the Frequencies?

Generally, A wireless network will transmit at a frequency level of 2.4 GHz or 5GHz. Mostly, depending on the user’s needs, the 802.11 networking standards will somewhat vary.

802.11a – It is transmitted the data at a frequency level of 5GHz

802.11b – It is transmitted the data at a frequency level of 2.4GHz. This is a relatively slow speed and it can transmit a maximum of 11 megabits of data per second.

802.11g – It is transmitted the data at a frequency level of 2.4GHz. And it transmits a maximum of 54 megabits of data per second.


Sinhala Blog

When we use and work in the internet, we have to click many websites to get information. There are many websites which are created in very attractive ways. But creating own website is not easy task to everybody. So, creating blogs is the alternative option for that. In Sri Lanka also, we can see many blogs and they are running as Sinhala Blog. These Sinhala Blog are created based on various kind of themes and when comparing to other countries’ blogs, there is less amount of Sinhala Blog in the internet.

Sinhala Blog and Blogging History

When we look into the history of bloggings, it runs to 1994. Justin Hall, was a student who created the first blog called in 1994. Actually, in these years it is not used name as blogs for these creations, it was called Personal Homepage.  In 1998, the first news blog was created by Jonathan Dube and it was called “Weblog”. In 1999, Peter Merholz shortened that name – “Weblog” as to “Blog”. In the early years, these blogs are updated manually. Thus, the blogging platform called “LiveJournal” was popular at those days. As the first time, Evan Williams and Meg Hourihan at Pyra Labs introduced the most popular modern blogging platform, called Blooger.

There was a growth for blogs at early 2000s. And according to the data, in 1999, there was 23 blogs on the internet. And it has growth upto 50 million blogs in 2006.  In 2001, Movable Type, one of blogging platforms was introduced and in 2003, WordPress one of popular blogging platforms was introduced. And in 2004, the first Video Blog was started. The AdSense advertising platform, which was the first ad network to match ads to the content on a blog, was launched in 2003. And according to statistical records, in 2005, there were 32 million people used to read blogs. After that, the concept of microblogging was introduced and twitter and Tumblr are some of them.

However, the blogs are popular among internet users, today and we can see less amount of Sinhala Blog there too. But with the rise of social Medias, there is less demand for blogs, especially for Sinhala Blog in Sri Lanka.

www – World Wide Web

Everybody who uses the internet, knows the word www . Do you know the meaning of this word? World Wide Web is the meaning of this www . Today, all websites which are communicating through the internet is moving through this www. The history of this www runs to 1989. Sir Tim Berners-Lee, a British computer scientist introduced this www to the world. His father was also a computer scientist.

History of www

After graduating from Oxford University, he was able to become a software engineer at CERN Company, Switzerland. When he was working there, he noticed that other engineers were having difficulty sharing information. So he started to find a solution to solve this problem.
One time, Tim has said like this “there was different information on different computers, but I had to log on to different computers to get at it. Also, sometimes I had to learn a different program on each computer. Often it was just easier to go and ask people when they were having coffee…”.
However, he tried to find a way to share information by exploiting an emerging technology called hypertext. He presented his idea by a document called Information Management; A Proposal. Unfortunately that document was rejected. His boss Mike Sendall, noted the words “Vague but exciting” on the cover of that document. Actually, www is not a project of CERN. But Mike Sendall allowed Tim to work on that project since 1990. He started his project by a NeXT Computer.
Tim was able to find three fundamental technologies for the foundation of today’s Web, in October 1990. They are;
HTML: HyperText Markup Language
URI: Uniform Resource Identifier (Addresses that we are using to find each resource on the web)
HTTP: Hypertext Transfer Protocol
The first web page editor/browser was created by Tim. It is known as Along with that, the first web server was also introduced. It was httpd. At the end of 1990, the first Web page was served on the open internet. And in 1991, the people outside of CERN were also invited to join this new Web community. At this time, Tim realised that its true potential would only be unleashed if anyone, anywhere could use it without paying a fee or having to ask for permission.
Therefore, he and his team tried to explain that idea to CERN management to make the underlying code available on a royalty-free basis, for ever. Finally this decision was announced in April 1993. As a result of that, the Web is spreading all over the world. How fast it has grown is that almost 2/5 people around the world were using the Web when the Web celebrated its 25th birthday.
In 1994, Tim moved from CERN to Massachusetts Company and he established World Wide Web Consortium (W3C). It is a community that involved to make open web standards. The early Web community produced some radical ideas that are now spreading far beyond the technology area. They are;
Decentralisation – No permission is needed from a central authority to post anything on the Web.
Non-discrimination: If any one pay to connect to the internet with a certain quality of service, and if any other one pay to connect with that or a greater quality of service also, then both of them can communicate at the same level.
Bottom-up design: It was established in full view of everyone, instead of code being written and controlled by a small group of experts.
Universality: It is for anyone to be able to publish anything on the Web.
As a result of that, today we can see there is a rise to approach in fields as diverse as information (Open Data), politics (Open Government), scientific research (Open Access), education, and culture (Free Culture). However, in 2009, Sir Tim established the World Wide Web Foundation and he has done a great change in technology world via this www (World Wide Web).


Google Gboard A New App to SMART Phones

We know that Google is one of fastest search engines and many of internet users are surfing on it. As another innovative technological step, Google has introduced a new App to SMART phones. We are sure that most of Sri Lankans don’t aware much about it as it has not arrived to Sri Lanka. However, this new app is called Google Gboard. So lets discuss what is Google Gboard.

Google Gboard Features

This Google Gboard app has several new features. Generally, when we chat with someone and when he/she is asking address of any particular hotel, what we did until now is, we are leaving from our texting, open search on web, find the hotel, copy the address and switch back to our chat and paste the address of that hotel. But if you have a Google Gboard app in your SMART phone, you don’t want to do that process again. You can search and send all kinds of things right from your keyboard with this new Gboard. Earlier, everything you’d search on Google, you can search with Gboard now. At this Google Gboard, the results appear as cards with the key information front and center, like the phone number, ratings and hours. So, you will able to send it to your friends with one tap and you can keep the conversation going also. Not only that, but this Gboard also sends anonymous statistics to Google to help us diagnose difficulties when the app crashes and to let us know which features are used most often. See how Google has made your life easy!
Actually this is a keyboard which is searching and sending all stuff that you want. And this keyboard will be highly useful for iphones. As iphone’s keyboard has some limitations, this will be more helpful for iphone users. You can view it well from below video also.
