What is Ethical Hacking? Who is Ethical Hacker?

We all heard of Hacking and Hackers in news. We think that Hacking is a bad thing and Hacker is a bad person. But you're not completely true. Hacking is not bad thing but when anyone Hack for a bad thing, then it's not good.

Well In this Post, we're going to tell you all about Ethical Hacking. So let's Begin...

What is an Ethical Hacker?

An Ethical Hacker is a person who Have in a system or network legally, ethically and with a proper permission. Ethical Hacker is defined as a person who works for a particular organisation. An Ethical Hacker hacks into a system or a network to check out it's vulnerabilities and security problems. He also checks it's security's penetration power.

Ethical Hacker is also known as “White hat Hacker”.

What is Ethical Hacking?

Apart from testing works, ethical hackers are associated with other responsibilities. The main idea is to replicate a malicious hacker at work and instead of exploiting the vulnerabilities for malicious purposes, look out the ways to shore up the system’s defenses. An ethical hacker might uses some of these strategies to penetrate a system :
  • Scanning ports and looking vulnerabilities : The vulnerabilities with each of the ports can be studied and fixed.
  • An ethical hacker tests patch installations and make sure that they can't be exploited.
  • The ethical hacker may engage in social engineering concepts like dumpster diving—rummaging through trash bins for passwords, charts, sticky notes, or anything with crucial information that can be used to generate an attack. 
  • Sniffing networks, bypassing and cracking wireless encryption, and hijacking web servers and web applications but in a legal way.
  • Ethical hackers also handle issues related to laptop theft and employee fraud.

Technical Facts

In this article, I am going to tell you Top 10 Facts related to Technology. Don't forget to follow me on Twitter. Let's get started...

  1. Now a days, we are using the pen drives having storage of 32GB and 128GB. But the First Harddisk named IBM 1311 have size of about a Washing Machine and have storage only of 5 MB. So huge!!!
  2. Normally, humans blink their eyes about 20 times but when they are using computer, they only blink for 7 times.
  3. The Windows we all use in our PCs is a project of Microsoft. In the beginning of this project this was named as “Interface Manager”, later on it was changed to “Windows”.
  4. In a month, an average of 6000 computer viruses are developed.
  5. The USB drive which completely damage a computer system is known as USB Killer.
  6. The first 1 GB hard drive was announced by IBM in 1980 which costs about 2 crore rupees.
  7. The 12 Engineers group who development first computer of IBM named as "The Dirty Dozens".
  8. The first microprocessor which was designed by Intel was for a Calculator.
  9. “I love you” is the name of the most dangerous virus still. It was a work, which replicate itself and fill your whole hard drive.

What is 3D Printing? How it Works?

A 3D printer can't make objects magically on demand. But day-by-day upgrading 3D printing machines begun to revolutionize the business of making things in this real world.

Working of 3D Printer

3D printers come in action by following some computer's digital instructions to "print" make(print) by the use of materials like plastic, ceramics and metal too. 3D printing process involves making an object layer by layer. For instance, few 3D printers eject out a stream of heated, semi-liquid plastic that solidifies as the printer's head moves around to create the outline of each layer within the object.

All instructions followed by 3D printers in form of computer-aided design (CAD) files — digital blueprints for making many kind of objects. A person can easily design an object on their computer, using 3D modeling software, connect the computer to any 3D printer, and the watch the 3D printer making the object in front of you.

History of 3D Printing

Chuck Hull is the inventor of the First Commercial 3D Printer. He offered this printer for sale through his company 3D Systems. Hull's 3D Printer used stereolithography, a technique that uses a laser to solidify an ultraviolet-sensitive polymer material (known as Photopolymer) wherever the ultraviolet laser touches it.

Limitations of 3D Printing

Everything has its own limit. 3D Printers also have some limits. 3D printers can only print anything with a specific material so they can't create complex things like an Smartphone. But the researchers are trying to upgrade the powers of 3D Printers, so they will be able to create such complex things.

Have you ever thought to print a 3D Object. If yes, then tell me what is it, in comments.

What is a Monitor? Types of Monitors

Monitor is the most common form of output from a computer. In this place information in the cemetery to that phone on a television screen. The picture on a monitor made up of thousands of tiny colored dots called pixels.

Types of Monitors

1. Cathode Ray Tube 

The CRT works in the same way as a television - it contains an electron gun at the back of the glass tube. This fires electrons at groups of Phosphorus dots, which coat the inside of the screen. When the electrons strike the Phosphorus dots they grow in to give colours.

2. Liquid Crystal Display

Liquid Crystal is the material used to create each pixel on the screen. The material has a special property — it can ‘polarise’ light depending on the electrical charge across it. This feature allows the pixels to be created. Each tiny cell of liquid Crystal is a pixel.

TFT(Thin Film Transistor) is the device within each pixel that sets the charge. And so sometimes they called “Liquid Crystal Display” referring to the material is the use all they are called TFT displays referring to that any transistors that make them work. TFT is a variant of LCD Technology.  LCDs use much less power than a normal winter.

3. Plasma monitors

Plasma monitors or PDP (Plasma display panel) are flat panel displays. The plasma technology utilizes same cells containing electrically charged ionized gas is across the face of a Plasma display to collectively from a visual image. 

Plasma monitors are not popular choice as computer mattress because of their expense, weight, power consumption and size. However, they offer a wide range of contrasts and colours and have a long display life so they can be used for years without going dead.

4. Touch screen monitors

Touch screen monitors are built by combining Touch sensitive materials with a durable but sensitive outer material that protects the mitre from fingers but still allows the monitor to detect where a person is pressing his fingers. Touch screen displays are used in tablet PCs check out store terminals and smartphones etc.

5. Organic light emitting display (OLED) monitors

OLED monitors are created from pushing and electronic current through organic materials, causing these materials to blow. By manipulating the materials and the electric current, the globe can be made to be of desired colour.
