Google Search is a web search engine, which is Google's core product. It receives over 3 billion search queries per day. Google also offers regional search by its 189 regional level domains.
There are a lot of words that get thrown around but it seems 2 of the more confusing are "browser" and "search engine".
Both of them are software. Both of them are found when using the Internet. They work together but there is a BIG difference between them.
1)Browser
A browser is a program that takes all the various pieces of a website (pictures, articles, presentation features like color and fonts) and puts them together so that you see them as an integrated website.
The top browsers in use today are:
- Internet Explorer, Google Chrome, Mozilla Firefox , Google Chrome, Safari, Opera, AOL (usage is becoming significantly smaller every year)
2 Search Engine
A search engine does what the name suggests. It searches for relevant websites based on key words. If you want to know about something, you type it into the search engine and it will give you thousands (millions sometimes) of websites that have one or more of the key words associated with them.
The top search engines are:
- Bing ,Yahoo (Note: Bing and Yahoo are in the process of merging)
- Ask , AOL
Each search engine has a different way of storing information about websites and determining in which order they should be displayed.
A search engine is a website that is used to find information on the internet, based on a word or combination of words. An encyclopedia of information relevant to the subject/topic of interest is available on the Web, but one should know how to find it fast. To search for information, just type a search term (a word or combination of words) in the search box and click ‘Search the Web’. Now, its popular Internet- related services and products are as follows:
1. Search engine and browser: Google’s core services is their web search engine, Google Search, which returns extremely relevant websites images. Google Chrome is the most widely used freeware web browser
2. Translation: Google Translate is a machine translation service, which can translate between more than 35 different languages. Google Translate is a multilingual service provided by Google to translate text, speech from one language into another.
3. E-maps : Google maps is a web mapping application that shows satellite images for most urban areas all over the world. It provides a route planner for directions for driving or walking. Google earth is a virtual globe – a geographical information program in which one can view the whole earth in 3 dimensions, including the ocean floor. Google street view integrated into the program provides an “on-the-street-level” view in many locations. .
4. GOOGLE MAPS: IS FOR ROUTING AND GETTING TO PLACES.
When it comes to finding places to go and how to get there, most people should just reach for Google Maps. The amazingly up-to-date information both in terms of maps themselves and points of interest are really top-notch among mapping software, and whether you're driving, walking, biking or taking public transit Maps really has you covered for turn-by-turn navigation.
5. GOOGLE EARTH: IS FOR EXPLORING
Google Earth is worth having around. Even though Google Maps offers a basic satellite view, if you want to really look around and see what things are like, you need to open Earth instead. The satellite view within Earth is dramatically higher resolution and more complex than what you'll get in Maps, and includes full 3D rendering of that satellite data so you can get a feel for the size of buildings and topography of the areas you're exploring.
6. Online Productivity services:
Gmail- Google-owned, web-based email service provides details of storage, options and links to related services.
