The web is a large collection of connected computers and software that talk to one another. They use client/server methodology to request and return information. It is analogous to a restaurant.
Your ‘client’ (PC, MAC, cellphone, tablet, etc.) asks a ‘server’ computer for information, If it can, the server returns it. The reality is more complex, but logically, it is the same whether you are querying your bank, Google, Bing, Amazon, the IRS or even your favorite porn site.
The web has many parts, but there are 3 basic components everyone needs to understand:
- Client devices
- Search Engines (indexing servers)
- Content Servers
Client Devices
A client is a hardware device with web browser software installed. It gives you a way to interact with the web. There are web browsers available for most devices you use like: Chrome, Firefox, or Opera. There are others that are specific to particular platforms like Safari for Apple or Edge for Windows 10.
The browser is your primary link to the web, and you need to understand the specifics of any browser that you choose to use. They are generally similar, but each has its own place to enter address information, unique ways to customize it, and specific ways to display multiple results.
Search Engines
Search engines are specialized servers that provide maps to information scattered around the web. In a sense, they are like all other servers except that they provide links to the things you ultimately want to use.
When you search for something on the web that request is usually directed to a search engine. Search engines typically return a list of possible places to go on the web that relate to your search. Examples of search engines include google.com, yahoo.com and bing.com.
Content Servers
Content servers are the destinations that provide the information that people ultimately seek. These web servers are the collection of all computers that store the information we use. They include computers that store your bank account and credit information, news sites, streaming sites like NetFlix and YouTube, Amazon, Ebay, Facebook, Twitter, and every other content you can imagine.
