INTRODUCTION ENTERING THE INTERNET WORLD

Posted by daeryl 7:53 AM, under |

I've entered the world of the Internet. Actually what is the internet? The Internet is an abbreviation of the Interconnection Network. In terms of origin of the internet he said significant relationship between computer networks (network). While the network itself is defined as a system of data communication between computers. Examples of computer networks that most often we find for example a LAN (Local Area Network) that connects computers located in an area or location such as offices, schools, companies, internet cafe, and others. Put simply be described that some computers are connected to each other to form a computer network (network), then a computer network (network) which join to form a set of network called the Internet. Thus, understanding the Internet in general (by language) is a collection of computer networks that connect and work as a system. The understanding of the Internet in particular (this is often used and what we mean in this discussion) is a computer network of the largest in the world for being able to connect all computers in the world. In summary, the Internet is a global computer network while the local computer network (eg LAN) is called Intranet. How can a computer to connect to the Internet? To get Internet access, a computer must use the services of internet service providers or Internet Service Provider (ISP). With this ISP business services, we can get the Internet (online) after connecting our computers to server computers. Relationship (connection) between the user computer (user) with the ISP company server computer is usually done through the telephone network (dial-up) by using modem equipment. Through the ISP's server computer that we can connect with the worldwide computer network (internet). Modem (Modulator-Demodulator) is an electronic device that can convert serial data held by the computer into the audio signal which is owned by a telephone cord and vice versa, from the audio signal into serial data. I often find the following terms on the Internet: HTTP, URL, WWW, HTML, Web Site, Home Page, and others. Would you please explain one by one on those terms! HTTP (Hypertext Transfer Protocol) is one of the protocol language used to communicate between the server computer on the internet. Protocols other language in the internet for example: Telnet, News, Gropher, FTP. URL (Uniform Resource Locator) is a system of naming a web site address. Therefore, URLs are often called Internet Address (Internet address). Each language protocol (HTTP, Telnet, FTP, etc.) have a writing system different address. Example: http://www.elexmedia.com/index.html. WWW (World-Wide Web) or summarized the Web is part of the HTTP protocol of the most popular language in the Internet. This system was originally the home-built by CERN, a physics laboratory in Europe and just beginning to be held for the public in 1991. Now, the Web or the Internet has become a source of data and limited information that is not accessible to everyone. In the WWW all documents, menus, indexes, etc. appear to Internet users as objects in HTML format that can be viewed by using a Web Browser. HTML (Hypertext Markup Language) A programming language used to write a document format that can be used in the Web. By using the HTML format of each document created can be read by all operating systems and types of computers in the world. In addition, the main strength of the HTML file is a hypertext link function (abbreviated: hyperlink). Hyperlink (Hypertext link) or commonly summarized the link is a specific part (can be text / text or image / picture) in an HTML document that refers / refer to any other documents or other parts of the same document. A text link is usually indicated by underlined text and is generally blue. But the main sign of a link (either text links or image links) are changing the mouse pointer into a "finger hand" when placed on a link. If a link is clicked then the browser will open a document / file pointed to by the link. Web Browser or summarized browser is a program or software designed to locate and display web documents in HTML format. With the browser, computer users can search and view the contents of a web document and move from one place (page) to another place on the web. Examples of browser programs such as Netscape, Internet Explorer, Opera, Mozilla, and others. Web Site or the Web site is any computer on the internet which acts as a web server that stores documents in HTML format. Web Page or a web page is an HTML file that is stored by the server or web site. Home Page is the "first page" of a web site that is the face or the initial view of an individual or institution that makes the web site. E-Mail (electronic mail) or electronic mail is a written message sent from a user's computer to another computer user. Electronic mail is stored beforehand in the server that provides email services. Chat is an internet facility which enables a number of users who join in it to talk directly (real time) through the typed text. Example of a famous chat program IRC and ICQ. Mailing List Mailing List is a collection or abbreviated list of a number of email addresses that are combined into a single email address that called the mailing address. Emails sent by a member of the mailing to the mailing address will be accepted by all members of the relevant mailing list. Download ie retrieve files from the internet (from the computer server to the computer user). Files that are downloaded can be a program file (software), documents, images, audio, video, and others. Upload (as opposed to downloading) is sending files to the Internet (from the computer user to a computer server).

(4) Tips & Tricks Using Search Engines

The only equipment or facilities that are used to explore various data, information and knowledge available on the internet is a search engine or search engines. Search engine is a program that can be accessed via the internet that serves to assist computer users in finding what he wanted. One of the most popular search engine is Google which can be accessed at the address http://www.google.com/. The main elements of a Search Engine is a long box where you enter keywords into stock early in the search for what we are looking for. After that press the Enter key or click the Google Search button. Google will search the entire computer connected to the internet various types of data in the form of documents, images, audio and video which contains a word that we enter earlier. Google will display a link (address) to all sites associated with these search results. We just click on one of the links that are relevant to be able to access the document in question. Write the keyword is correct because Google will search for the exact same words that we write. Writing the word Amen, and Amien would give different results. On the other hand, Google does not distinguish between uppercase and lowercase letters. Writing keyword or even a Celebes or Sulawesi Sulawesi, will give the same results. Every word is entered into the search box, will be searched separately. When we enter the keyword as follows: [Prince Diponegoro] then Google will find Web pages that contain the word prince and web pages that contain the word Diponegoro. That is, words and word prince Diponegoro in the documents found by Google was not necessarily in tandem, could be mediated by other words. Even including the web pages that contain the word but does not contain the word prince Diponegoro. Use quotation marks (") that flank the phrase (plural) or a specific wording to force Google to find web pages that contain the same wording without interspersed by other words. For example: [" Prince Diponegoro "]. The technique is very effective way to get search results that are truly relevant and focused on the purpose for which we are looking for. Use the plus sign (+) to require Google search only web pages that contain all keywords you enter. For example: [+ scholarship + master + "outside country "]. As a result, Google only returns web pages that contain all these words. With this technique, a search Google will increasingly sharp and focused. Conversely, if we wish for a keyword is not included in the site found in Google, we use the minus sign (-). For example: if we want to look for scholarships as above but do not want to school in America or Australia, then we can write: [+ scholarship + master + "abroad"-America-Australia]. This technique can used to narrow the search results. In general, large sites that already provide local search facilities to their web sites each. Search engines, these local functions to search for key words found on their web pages themselves, not looking at other sites. But if one day you find a site that does not yet provide local search engine, you can use Google to search for key words on the site by using the word site followed by a colon and name of the site (its quasi-no spaces). For example: we want to find articles and news related to the problem of corruption in the Republika newspaper website, then we write: [corruption site: republika.co.id] or [site: republika.co.id corruption]. The technique can also be used for direct searches on sites with certain characteristics. For example, if you want to find information about corruption from the sites of education (education), you can write: [corruption site: edu] in the search box. If you want to look for the site government-official site (government), write: [corruption site: gov]. To know the meaning of the domain, please read the article about the meaning of the Domain. For those of you who are looking for files with certain formats to be used as a reference, to use the word filetype: in a search. For example: [filetype: ppt + tutorial + coreldraw]. In this way, Google's search focused only on those files PPT (Microsoft PowerPoint) that contain these words throughout the website. The same way you can use to look for DOC files (MS Word), XLS (MS excels), PDF (Adobe Acrobat Reader), and others. Once Google displays its search results, check where roughly consistent with the purpose of your search. The you need to consider is the context around the keyword phrase you are (bold) and name / website address listed below. If you want to open a link provided by Google, right-click on the link and select open in new window to window Google itself still exists and is not replaced. So you still can see and open other links displayed by Google. If you still want to check Google search results contained on other pages, click on the link or the page numbers listed next word at the bottom of your results page pencarian.Bila still not satisfied with Google's search results, you can take advantage of Google's Advanced Search facility which will make it easy for you to manage what should be searched by Google, for example in terms of language, filtering, file format, The new information is updated and others.

(5) Tips & Tricks to Avoid Password Theft

One form of Internet crime is dangerous is password theft. If your email password is known by others, then he will be free to peep the content of your email. Maybe there is a saying, please read the contents of my email, nothing needs to be kept secret in it koq. Though the problem is not that simple. If your password falls into the hands of others, he was free to change the password. As a result you can not open (log-in) email. Not only that, he could also send an email to someone else using your email to incite or other malicious intent. Again, you are responsible. For that we must know how to keep our passwords. We must first know how someone can know the password to others. In outline, there are four ways people steal passwords to others.(I). Utilizing the negligence of the owner password. For example, there are others who see the movement of his hands when typing passwords. Or there are others who find notes containing passwords. So, be careful when typing in passwords and wherever possible you should never store or write your passwords. Use your brain memory for storing passwords. Or if you have to write it, save it in a place that is hidden and not obvious as a password.(Ii). Guessing. It is very difficult and very rare. Is only possible if your password is too easy to guess (example: 111111 or asdfgh). Including when you use the name or specific number of known and easily exercised by your friends. Therefore, as far as possible do not use the password is your phone number or date of birth or the name of your wife, and semisalnya.(Iii). Utilizing a secret question. When registering on the site free email providers on the internet, in addition to passwords, usually we are given the opportunity to choose a question and enter the answer. This serves as a backup in case one day we forget our passwords. Many people often include a question and answer potluck. And people can use this facility to steal your passwords. When will sign up with your email, he chose the lost password (forgot password) so that the email program will issue the first question you submit. Therefore do not use questions that are too easy to answer.(Iv). Using a keylogger software. Keylogger program is a program that works behind the scenes, meaning he works unconsciously by the user computer (unless the installer program of course). This software can record every key pressed and store it in a particular file. If you already use a computer, the installer keylogger program, will take over the computer, open the file and look for traces of earlier recording your passwords in it. Although very, very many letters that are listed in it, he could find it in some way. Usually we write the password after you enter the name of the email. Letter or number after that is a password. This case usually occurs on computers that are used by many people (for example in the cafe or offices). To avoid this kind of password theft is a bit difficult. But still there is just way out. Before using a computer, first press the key combination Ctrl + Alt + Del. Close Program window will appear that displays all programs currently running on that computer. Find the program that you expect is the name of the keylogger program. If you do not know his name, choose the program you do not know and then click End Task button to close the program. Other applications can you let it, like the Explorer, dorm, Mdm, antivirus programs, internet cafe billing programs, and other programs that you know. In this way, can we assume that there is no keylogger program that was working.But maybe we can not find it and close the keylogger program. Moreover, many keylogger software that can hide themselves in such a way. But do not worry because there is only solution. The fix, do not type directly in full all our passwords in the password text box. For example, our password: "parasites". Type the first letter "be" and then move to another program window and then type any letter a lot there. Then moved back into the password field and then proceed to type "na". And then moved again to another window and type in many letters any more, then back again into the password field to refine them with the letter "lu". Thus the program recording keystrokes (keylogger) will record a lot of letters that may be irregular sure the thief is unable to separate the letters of the password which we are stuck in it. This is due, keylogger programs generally do not differentiate in the window where you type a letter. He only serves to record the keyboard keys are pressed.(V). Using the remote program. This program is related to the networking problem (network computer). There are a number of software that can control a computer remotely. This software is installed on their computer as a server and installed in someone else's computer as a client. As long as we are computers connected to the network or the Internet, he can read what we type in, even knowing the contents of our hard disk and see the look on our screen! To deal with these cases is the most difficult and it took its own tricks. When he uses way to record keystrokes (keylogger), we can still overcome by way of writing to move the window as above. Adapaun when he used a remote program that is able to see the look on our screen, is the most difficult to overcome.
