Bandwidth Vs Download Speed Are they same?

The answer is NO... because Bandwidth is the maximum traffic capacity of your Network and Download Speed is what you actually get. Let me explain...

Download Speed depends on two factors. One is Bandwidth. Another is Latency (Also called Delay). Bandwidth is the amount of data that can be transferred during a second. It is normally expressed in bits per second.

Latency is the Round-Trip Time (Host Server -> Destination Server -> Host Server) taken for a small packet of data (usually 32 bytes) when you ping with CMD (Command Prompt). Pinging is a method to measure latency. Latency is normally expressed in milliseconds. Latency increases either if the distance between the Host Server (Your Computer) and the Destination Server (Any Website) increases or if there is a congestion in the traffic. But Latency will not necessarily decrease even if Bandwidth is increased. Why?

In simple terms, Bandwidth is like the width of a pipe. Latency indicates the time taken to cross a particular distance by the flow inside the pipe!! Both these factors together determine the end-result (Download Speed). Got it?

The next-time you communicate with your ISP (Internet Service Provider), don't forget to ask your actual Download speed!!

Google Rolls Out Google Swirl Image Search Engine

this is the latest news about google
Google has rolled out yet another cool google lab feature on 15th november. Google has always been the first to roll out some unique features. Google swirl image search engine not only finds out similar images but it divides them into the group and sub-groups.

Basically Google swirl groups the images according to searched keywords. When you click on the image it will form a cluster of all images. The clustering is done based on the similarity of the images.

Swirl search engine is basically based on the technique called “Similar images” and “Picasa face recolonization” to which decides how to group the images in groups and hierarchies of the group.

You can check the search engine in work from here http://image-swirl.googlelabs.com/

What is an IP Address?

IP address (Internet Protocol address) is a unique number that distinguishes one device from another on the Internet. In layman's terms, it is the same as your house number. An IP address serves two principal functions; identification and location addressing. This enables one to communicate with other computers all over the world.

There are two versions of Internet Protocol.

IP version 4: Currently used by most of the network providers. However, with more and more computers accessing the internet, IPv4 addresses are running out quickly because they are limited to approximately four billion only (256 to the fourth power).

IP version 6: The replacement for IPv4 has a vast range of IP addresses, inexhaustible for all practical purposes. The estimated number of unique addresses in IPv6 is trillions of trillions!!

In IPv4, an IP address is made up of four numbers, each between 0 and 255. The general information is conveyed by the first number, and the specific identification of a computer within a network is usually made by the last number. The IP address 0.0.0.0 is usually reserved for the default network and the address 255.255.255.255 is used for broadcasts.

IP addresses can be permanent or temporary.

Dynamic IP Address: When a home PC dials the Internet service provider (ISP) through modem/ router, an IP address is temporarily assigned from a pool of available addresses for the duration of the call. This IP address is not static and could change the next time.

Static IP Address: An IP address that is fixed and never changes. A single or a block of static IPs can be obtained for a few extra bucks a month from most ISPs (usually meant for Email/ Website servers).
