Understanding What DNS is All About

Recent browser developments have included “DNS” in their features. Ordinary netizens like us may not really understand what it is all about, but some claim that it speeds up web browsing. For some people interested in building or creating a website, understanding DNS and how it can change our browsing experience is very important.


DNS actually refers to Domain Name System which is a massive database that allows you to browse and download files or applications from the internet. When you type an address on your browser, your ISP or internet service provider sends out a search request on a DNS which then searches for the IP address of the site you are looking for and then sends it back to you.

It is used for emails, web pages and several other things that you do on the web. Unknowingly, you may actually be sending hundreds or thousands of DNS requests in a single day. Sometimes it takes more than one IP address to display everything on a single website especially in the case of adverts which are also located on other servers.


DNS is truly an amazing and fascinating database that resolves the alpha-numeric address you have keyed-in an IP address and gives you the webpage that you need. This process happens really quickly between your computer and multiple DNS servers and you won’t even know how it goes, what’s important is that you get the webpage you want and you’re done.

Know the hiding places of Malware

If your laptop or personal computer becomes suddenly unusually slow and your antivirus program unexpectedly stops working, then a malware might have slipped through the cracks which your antivirus might have failed to catch. Most modern day malicious programs use technically sophisticated defenses which makes it tougher for users to detect and remove.




A malicious software or commonly known as malware is a computer program designed to specifically disrupt and damage a computer system. It is typically in the form of a Trojan horse or a virus that interferes with the normal function of your computer to gain access into your files and personal data then send it to unauthorized parties over the Internet without your consent.

Removal is not as easy as 1,2,3 especially for people who are not computer experts because once your system is infected, the malicious program will does not simply sit in an obvious location, it will hide and move around in your computer system to prevent detection.

Ever Heard About Cloud Computing?

You’ve been using the internet for many years now, but have you ever heard about cloud computing yet? Just recently, the term “cloud” slowly became a household word and more people realize that they had actually been using it through the processes they do on the internet. Computer wizards and geeks have known what cloud computing is for so long but there is no equal layman’s term for it. It simply refers to the storing, retrieving and processing files on your computer or another device. Browsing the web, sending an email, using different online applications means you’re on “cloud computing.”

Difference between Static and Dynamic IP addresses

An Internet Protocol address or what is known as IP address is a numerical label or binary codes separated by three dots like for instance, 112.–.–.– which is assigned to each computer device and identifies that particular computer on the internet. Every computer requires an IP address to be able to connect to the internet.

The Internet Service Provider or ISP will assign your IP address either a Static or Dynamic depending on what plan have you availed. The difference between a static and dynamic address are as follows:   Continue reading

Virus 101


Virus or computer viruses are uninvited visitors of a computer unit. Early viruses are self-replicating program that floods the network and usually send spam messages. The first known virus is known as “Creeper” wherein it will send out a message saying “I’m the creeper, catch me if you can!” to the network. Later on, Reaper was created to delete the Creeper virus.

People are usually confused about computer viruses, Trojan horses, computer worms, rootkits, spyware and adware. Here is a short description of their differences:

• A computer virus is a program that can easily multiply and can infect one computer to another and needs to attach itself to a computer program.

• Trojan horses, just like in the Trojan War where the Greeks gave the city of Troy a wooden horse as a gift, with a bunch of men hidden inside. Trojan horses can steal information or harm their host computer systems by disguising as a helpful program which will eventually allow other viruses to infect your computer.

• Computer worm is somewhat similar with a computer virus but it doesn’t need to attach itself to a computer program and it frequently needs a network to multiply.

These three are the major types of Malware (Computer Virus, Trojan horse and Computer Worm)

Rootkit came from the word root plus the word kit. Root refers to the target computer and the word kit is pertaining to the set of tools used to gain access to the target computer with administrative privilege. Rootkit usually hide its existence from antivirus and modifies the operating system to hide the malicious activities performed by the attacker.

Spyware is another type of malware wherein the actions of the computer user is being monitored by a software hidden in the computer. The main purpose of this malware is to collect data and track the user’s activities on the computer.

Adware is the so-called unwanted pop-ups or sometimes a form of advertisement that shows up on your screen. It is somewhat related to spyware for it is mounted on users’ systems without their consent.

As we all know these computer viruses, Malware, Trojans, Rootkits, Spyware and Adware will cause inconvenience to each and every one of us, so we should be very cautious not to have any of these. As they say, prevention is better than cure and the most effective way of avoiding your computer from being infected is proper knowledge and good practice. Keep your antivirus updated! :)
