Globalization

It was the anti-globalization movement that really put globalization on the map. As a word it has existed since the 1960s, but the protests against this allegedly new process, which its opponents condemn as a way of ordering people's lives, brought globalizations out of the financial and academic worlds and into everyday current affairs jargon.

But that scarcely brings us nearer to what globalizations means. The phenomenon could be a great deal of different things, or perhaps multiple manifestations of one prevailing trend. It has become a buzzword that some will use to describe everything that is happening in the world today.

Whenever you make a certain investment in a product no matter how big that investment is, you need to make sure that you will see the return you expect. This is important especially if you are buying something specialized such as a printer expecting certain things from that machine such as printing quality, speed or any other specific characteristics. Have a look at this article and find out about the different types of printers and some of their characteristics.

1. 1st Type: Inkjet Printers
   These are the most affordable printers you can find in the market as they are massively produced due to their home use or small office suitability. Although they are very cheap to buy you will be spending your money depending on printing volume on ink cartridges.

What is a Printer?

A printer is an electromechanical device which converts the text and graphical documents from electronic form to the physical form. Generally they are the external peripheral devices which are connected with the computers or laptops through a cable or wirelessly to receive input data and print them on the papers. A wide range of printers are available with a variety of features ranging from printing black and white text documents to high quality colored graphic images.

Quality of printers is identified by its features like color quality, speed of printing, resolution etc. Modern printers come with multipurpose functions i.e. they are combination of printer, scanner, photocopier, fax, etc. To serve different needs there are variety of printers available that works on different types of technologies. 

Types of Printers:

Since the invention of the printing technology, a variety of technologies have been employed in computer printers. Broadly printers are categorized as impact and non impact printers. Impact printers are the type of printers in which a key strikes the paper to make a letter. The examples of Impact printers are Daisy wheel and Dot matrix printers. While non-impact printers do not operate by striking a head against a ribbon. Inkjet printers and laser printers are the non-impact printers. The most popular printers are described.

network

Definitions:

1. Computers: A group of interconnected (via cable and/or wireless) computers and peripherals that is capable of sharing software and hardware resources between many users. The Internet is a global network of networks. See also local area network and wide area network.

2. Communications: A system that enables users of telephones or data communications lines to exchange information over long distances by connecting with each other through a system of routers, servers, switches, and the like.

modem

Modulator-demodulator. Electronic device that allows computers to communicate over telephone wires or cable-TV cable. One computer's modem converts its digital signals (which cannot be sent efficiently over phone lines) into analog signals (which can be). The other computer's modem reconverts the analog signals (that the computer cannot understand) into digital signals (that it can). Conversion of one type of signals to another is called modulation, their reconversion to the original type is called demodulation. Modern modems work at 56 thousand bits per second (Kbps) or higher data transfer speeds, perform automatic error correction, and allow voice and fax communications. Cable modems offer 2 million bits per second (Mbps) or higher speeds, whereas advanced types of telephone services (such as ISBN) allow very high speed data transfer without any modem.

OR

A device for transmitting usually digital data over telephone wires by modulating the data into an audio signal to send it and demodulating an audio signal into data to receive it.

WiMax

Type of wireless technology that provides wireless internet service over longer distances than standard Wi-Fi. WiMax is based on standard IEEE 802.16 technology and can provide broadband wireless access up to 30 miles. WiMax uses fixed and mobile stations to provide users with access to high-speed voice, data, and Internet connectivity. WiMax technology has not been widely accepted by the technology community, but its popularity continues to grow as businesses and consumers seek out better ways to constantly stay connected.

What is "WiMAX"?

WiMAX is a wireless technology put forth by the WiMAX Forum that is one of the technologies that is being used for 4G networks. It can be used in both point to point and the typical WAN type configurations that are also used by 2G and 3G mobile network carriers. Its formal name is IEEE standard 802.16. Sprint owns a WiMAX based network that is marketed under the name XOHM, though that will eventually be merged with Clearwire's network and sold under the Clearwire name. LTE is a competing technology that has the support of far more carriers worldwide.
Also known as: "802.16"

Computer

A term that originally was given to humans who performed numerical calculations using mechanical calculators such as the slide rule and abacus that was later given to a mechanical device that was planned on being used to replace these humans. A computer is not an acronym, is sometimes abbreviated as comp or 'puter and is an electronic device that allows you to input data and have it stored, processed, or otherwise manipulated and if necessary output that data in an easy to read format.
Computers help make jobs that used to be complicated much simpler. For example, a user can write letters in a word processor and edit any portion of the letter anytime, spell check the letter, and move text from another document into the letter, etc. This is just one of millions of different things a computer is capable of doing.
The first computer was called the ENIAC, which was built during World War II. These early computers used vacuum tubes and were very large (sometimes room size) and only found in businesses, Universities, or governments. Later, computers began utilizing transistors as well as smaller and cheaper parts that allowed the common person to own their own computer. This history of computers and related topics can be found on our history page.
Today, most computers are often comprised with some or all of the below components.

Bay Case or Chassis Optical drive: Blu-ray, CD-ROM, CD-R, CD-RW, or DVD CPU (processor) Floppy disk drive Hard drive Keyboard Memory (RAM) Microphone Monitor, LCD, or other display device Motherboard Mouse Printer Sound card Speakers Video card

What is meaning of wi-fi?

Surprising how someone who actually linked to the Wikipedia article could miss this vital bit of information.

From Wikipedia:
The term "Wi-Fi" suggests "Wireless Fidelity", comparing with the long-established audio recording term "High Fidelity" or "Hi-Fi", and "Wireless Fidelity" has often been used in an informal way, even by the Wi-Fi Alliance itself, but officially the term does not mean anything.

So no, "Wi-Fi" does not actually mean or stand for anything, it's just a marketing term for any IEEE 802.11-compatible networking device.

PostHeaderIcon Definition and Various Types Of Cyber Crime

Cyber crime or computer crime is broadly defined as any crime committed with the involvement of computers and their network. Computers and network may or may not have played an important part. Net crime is crime committed through the internet. Crime with relation to child pornography, copyright infringement, child grooming and hacking have become high-profile now. There are other crimes in which highly confidential information is intercepted or lost. At the global level both governments and others continue to play an important role with the skills to conduct activities like financial theft and espionage and other crimes committed across the border referred as cyber warfare.
The international legal system is trying to identify those committing computer crime and hold them responsible for crimes with the International Criminal court addressing the threat to computers and the internet. Examples of computer crime and net crime are computer viruses, malware information warfare, identity theft, phishing spasm and cyber stalking. Malware is nothing but malicious code. Computer can be used an evidence since the cyber criminals leave a trace of their actions in the computer which records such information. Investigators can use such valuable information if they can get and decode it. Sending unsolicited bulk mail referred as spam is illegal. Computer fraud is any crime committed by way of dishonest misrepresentation of facts with ultimate objective of making individuals do or refrain them from doing something resulting in loss.
Altering computer input is absolutely illegal. Altering and destroying data are dangerous acts of cyber crime. Certain websites contain offensive or obscene racist and blasphemous information. Apart form usual types of computer crime all this the most harmful crime as far as children and adolescents is internet pornography. Another type of crime is harassment of people based on gender, race through obscene and derogatory remarks on the victim. Drug trafficking through internet is yet another type of net crime. Cyber terrorism activities like holding out threats to important people are also on the increase now. There are many more types of cyber crime being committed daily. Criminals are coming up with new methods to commit crime making addressing the problem more difficult.

Networking and the Internet

Visualization of a portion of the      routes on the Internet.

 

 

Computers have been used to coordinate information between multiple locations since the 1950s. The U.S. military's SAGE system was the first large-scale example of such a system, which led to a number of special-purpose commercial systems such as Sabre.^[48]
In the 1970s, computer engineers at research institutions throughout the United States began to link their computers together using telecommunications technology. The effort was funded by ARPA (now DARPA), and the computer network that resulted was called the ARPANET.^[49] The technologies that made the Arpanet possible spread and evolved.
In time, the network spread beyond academic and military institutions and became known as the Internet. The emergence of networking involved a redefinition of the nature and boundaries of the computer. Computer operating systems and applications were modified to include the ability to define and access the resources of other computers on the network, such as peripheral devices, stored information, and the like, as extensions of the resources of an individual computer. Initially these facilities were available primarily to people working in high-tech environments, but in the 1990s the spread of applications like e-mail and the World Wide Web, combined with the development of cheap, fast networking technologies like Ethernet and ADSL saw computer networking become almost ubiquitous. In fact, the number of computers that are networked is growing phenomenally. A very large proportion of personal computers regularly connect to the Internet to communicate and receive information. "Wireless" networking, often utilizing mobile phone networks, has meant networking is becoming increasingly ubiquitous even in mobile computing environments.
