How traceroute work ?

2010-02-09T00:27:00.006+06:00

Traceroute traces the route which packet goes through to get a certain IP or host name
The main purpose of using traceroute is to detect the network problem
For example: if you has a problem in a certain host and see where is the problem (you can see where the chain stops)

If you are windows user you can use tracert in cmd (windows command prompt) but if you are linux or unix user you can use traceroute

How does tracert or traceroute work ???

Firstly we must know little about TCP/IP packets.

TCP/IP pacets can be divided into two types :

IP packets
ICMP packets

Each packet contains two parts

Header part
[b]Data part

Header:
Contains information about the sender ,target and any other information that is necessary so packet c an reach it's destination

Thus ICMP packets have a header and data. There are about 13 types of ICMP packets one of them ICMP (echo-request ) packets which is used for pinging however ICMP mainly used for errors

Now there are IP packets having header and data part, The header contains the source and destination IP and few other values . For example :TTL

Come to data part of IP packet it can be TCP or UDP packets . This TTL value plays an essential role in killing misroute packets .suppose something happens and packet start looping or waner around the net endlessly that would be waste of bandwidth on the network.

So this is why the IP header contains TTL value and so does the ICMP header
This TTL value decrease whenever a packet goes through the router .Whenever the packet goes through the router the TTL value decrease by one

That’s why if the packet goes through too many hops on network on the way it get killed such as in case of looping . In this case ICMP error is sent back to the sender let me use windows 95 as example:

Windows 95 sends packets with TTL = 32 and if you have to go through more than 32 hops , you will get an error and windows will send the packet again with TTL = 64

Now we will show the steps of traceroute or tracert

1-First the packet sent with TTL=1

2-The packet goes through the first hop and dies

3-The router send back ICMP error and that way we can determine its IP or host name . as we can tell who is sending the packet by looking at ICMP header

4-Then tracert send a packet with TTL=2 it will travel to 2nd route passing through the first route (which we already known) and die in the 2nd route

5-We get now an error from the second route that revealing its IP

6-This will go on until packet reaches its destination

shortcuts:

TTL=(time to live)
ICMP=( internet contron messaging protocol)
IP= (internet protocol)
TCP= ( transmission control protocol)
UDP= (user datagram protocol)

Search Engine Tips

2009-07-12T06:43:00.006+07:00

The reason the Web is so powerful is that it puts an enormous amount of information at your fingertips. The challenge of navigating the Web is to find the information you want among a wilderness of millions of unorganized Web sites. Search Engines help you face this challenge by searching the Web for you. However, to use a search site effectively, you need to be very specific in your request. This booster will enable you to search the Web Steps to searchinga

1) Guessing URLs If you're looking for a corporation or institute, start by guessing once or twice what its URL (Uniform Resource Locator) might be. Businesses spend a lot of money to have an obvious and easy-to-guess URL, for exactly this reason. If you guess wrong, you'll be told "URL not found.

" Assume the URL starts with "www." End the URL with the correct suffix, as indicated below.

.edu = educational institutions (www.wagner.edu)

.com = commercial businesses (www.nike.com)

.org = non-commercial organizations (www.pbs.org)

.gov = government organizations (http://www.whitehouse.gov).uk/,

.ca, .nl = other countries have their own suffixes (.uk - United Kingdom,

.ca - Canada, .nl - Netherlands)

2) Use Web Site Listings If guessing doesn't work, the next step is to go to a search site. Web site listings are created by people who surf the Web for a living and manually record Web sites. These Web sites are then categorized and subcategorized into a hierarchy of sites. You can browse through these categories and subcategories until you get a listing of Web sites.

Web site listings are useful if you're looking for a site on a fairly general topic, one for which there are hundreds, or even thousands, of Web sites. For example, by using selected listings for a popular topic like "Star Wars" or "African bees,” you will avoid the unofficial and not-very-good sites and find only the best.

Try clicking through this path on Yahoo! You will end up with a listing of Star Wars sites: Entertainment --> Movies & Film --> Genres --> Science Fiction & Fantasy --> Series --> Star Wars

There you'll find the listing of Star Wars sites, wonderfully organized by subcategories (clubs, books, chats, screenplays, humor, etc.). You'll find the official Star Wars site, sites by Star Wars fans, and more.

You can also access the listings by using a search field. Try typing "Harrison Ford" in the search field below and press Submit to see the Yahoo! listings. As you see on the top of the Yahoo! page, Harrison Ford is listed under Entertainment --> Actors & Actresses.

Some Web site listings:

Yahoo! (http://www.yahoo.com/)

Excite (http://www.excite.com/)

In addition to portal sites like Yahoo! that specialize in search engines for the entire World Wide Web, many smaller sites provide a sub-set of the Web, highly filtered for quality and content. While they can be very helpful, Web site listings don't always work. It's much harder to search for specific information, rather than a subject area. For example, if you want to find a calendar that lists election days, then you might be better off with a search engine.

3) Use search engines. Search engine computers search the entire World Wide Web and create a huge, raw, and unfiltered listing of all sites, regardless of quality or type. When you submit to a search engine some words describing what you're looking for (keywords), it will provide you with a long listing of all sites related to your keywords.

Some search engines: Google (http://www.google.com/)

Alta Vista (www.altavista.com) Go.com (http://www.go.com/)

HotBot (http://www.hotbot.com/)

InfoSeek (http://www.infoseek.com/)

However, if you're not specific or careful enough in your request, you could be overwhelmed with thousands of links--and then you won't know which ones to start with.

Conducting a Basic Search Narrow your search with:

Specific words

The simplest way to search is to type in a single word. If the topic is narrow enough, that may be sufficient. For example, "dysphasia" might work, but "cats" will give you too many listings. Adding Quotation Marks Quotation marks specify phrases instead of individual words. Maybe you're looking for something that can't be expressed in a single word, such as "Persian cats," "computer games," "drug therapy," "stock portfolio," "sports cars." If you type in sports car (with no quotation marks), then you'll end up with a listing of every Web site that has the word 'sports' and every Web site that has the word 'car'.

When searching for a phrase, make sure to enclose it in quotation marks:

"cross-country skiing" "early nineteenth century literature" "Jane Doe" "Great Barrier Reef" Adding Plus & Minus Signs The plus sign (+) requires a search function to include specific words.

The minus sign (-) requires a search function to exclude specific words.

A (+) guarantees that a particular word will be in all the Web pages in your results listings.

A (-) guarantees that a particular word won't be in any of the Web pages in your results listings.

Capitalization Capitalization makes a search case-sensitive.

If you capitalize letters in your search, then you narrow the search to only occurrences of that word with the exact same capitalization. If your entry is all lowercase, then the search engine will search for all occurrences of the word, regardless of capitalization. The last thing you should keep in mind is that almost all search sites have an Advanced link next to the Search field. If you click on that, you'll be given ways to refine your search, such as by date and language.** Check the Internet Public Library for comparison of search engine's capabilities. Go to TopHow to recognize a good Web site from a bad one?

1) How did you hear about the Web site?

Is the site a brand name you're already familiar with? Was it recommended by a reputable source, such as another Web site you trust, a newspaper, or magazine? Or did you simply stumble upon it while surfing? With millions of Web sites at your fingertips, it's wise to use a good filter. ThirdAge.com, for example, provides Web Guides to sites we reviewed and found to match our standards of excellence.

2) What's your impression of the Web Site?

Is it up-to-date and accurate? It is professionally presented and maintained? Is a link to the individuals or organization behind the Web site (such as an "About Us" link) easy to find? If the site's creators don't want you to know who they are, that's a warning sign. Likewise, look for links to biographical information about the authors on the site. What are their qualifications?

3) What's the purpose of the Web site and are they trying to sell anything?

You can start by looking at the Web site address. For example, if the Web site is produced in the United States, it will likely end in one of the following: .com = commercial .org = organization .edu = educational .gov = government .net = network Always keep in mind the motivations of the Web site producers. If you're getting health information from a Web site built by a pharmaceutical company, then it's a good bet that the information may be biased towards that company's products. Advertisements are to be expected on any commercial site (just like you'd except ads in a magazine), but it's essential to confirm if the editorial content is fairly presented. In sum, what's the source of the information on the site and is it biased?

Third generation or 3G networks

2008-11-27T03:15:00.012+06:00

Third generation or 3G networks

Third generation or 3G networks represent an international standard for wide-area cellular networks that are replacing 2G networks. The main advantage of 3G networks is use of a wider radio spectrum resulting in faster data transmission for advanced multimedia services and a larger network capacity. Carriers can deliver these advantages at a reduced cost compared to 2G network technologies, though physical implementation of a 3G network can be expensive in some cases. 3G networks represent the natural evolution from previous standards. Increasingly cellular phones and handheld mobile devices have incorporated additional services to telephony. Today’s mobile devices offer high-speed World Wide Web access, emailing, messaging, video phone and multimedia services. People want to be able to watch streaming movies on their cellular phones, download and play music, store data and share files with other cellular users. 3G networks offer faster, slicker ways to do this. 3G networks have been in operation globally since December 2005 and are continuing to spread. Some telecommunication companies in the U.S., Canada, Asia and Europe use a flavor of 3G called W-CDMA (Wideband Code Division Multiple Access). Others use CDMA2000, a non-compatible, competing 3G standard that includes a small family of protocols. These are known as CDMA2000 1xRTT (1 times Radio Transmission Technology), CDA2000 EV-DO (Evolution Data Only), and CDMA EV-DV (Evolution Data/Voice). Two popular mobile carries that use CDMA technology are Sprint and Verizon. If your mobile phone utilizes a subscriber identity module or SIM card, your carrier is using a GSM (Global System for Mobile communications) network. GSM networks make the switch to 3G networks by first incorporating a General Packet Radio Service (GPRS). From here the network can be converted to a Universal Mobile Telecommunications System (UMTS), a 3G standard sometimes referred to as 3GSM. Alternately the network can incorporate an Enhanced Data rates for GSM Evolution (EDGE) system, though some people consider EDGE a 2.75G system since it is slightly slower than other 3G networks. In practical terms, if you are looking for a GSM mobile phone carrier and that carrier offers UMTS or EDGE, you know you are getting a 3G network. Alternately, if considering CDMA carriers, look for one of the CDMA2000 flavors mentioned earlier. Be alert for newer technologies as well. As you might have expected, there is already talk of 4G networks, and protocols will continue to evolve with time to define newer standards.

WiMAX

WiMAX is the next-generation of wireless technology designed to enable pervasive, high-speed mobile Internet access to the widest array of devices including notebook PCs, handsets, smartphones, and consumer electronics such as gaming devices, cameras, camcorders, music players, and more. As the fourth generation (4G) of wireless technology, WiMAX delivers low-cost, open networks and is the first all IP mobile Internet solution enabling efficient and scalable networks for data, video, and voice. As a major driver in the support and development of WiMAX, Intel has designed embedded WiMAX solutions for a variety of mobile devices supporting the future of high-speed broadband on-the-go.
WiMAX, meaning Worldwide Interoperability for Microwave Access, is a telecommunications technology that provides for the wireless transmission of data using a variety of transmission modes, from point-to-point links to full mobile cellular-type access. The technology provides up to 70 Mb/sec symmetric broadband speed without the need for cables. The technology is based on the IEEE 802.16 standard (also called WirelessMAN). The name "WiMAX" was created by the WiMAX Forum, which was formed in June 2001 to promote conformity and interoperability of the standard. The forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL"and also to High Speed Packet Access).[citation needed]
Currently, Pakistan has the largest fully functional WiMAX network in the world.Wateen Telecom installed the network (with an initial rollout in seventeen cities) throughout Pakistan using Motorola hardware. Wateen is also planning to expand its network and eventually cover 71 cities in Pakistan.
UsesThe bandwidth and range of WiMAX make it suitable for the following potential applications:Connecting Wi-Fi hotspots to the Internet.Providing a wireless alternative to cable and DSL for "last mile" broadband access.Providing data and telecommunications services.Providing a source of Internet connectivity as part of a business continuity plan. That is, if a business has a fixed and a wireless Internet connection, especially from unrelated providers, they are unlikely to be affected by the same service outage.Providing portable connectivi
