A site for sending and receiving files using an Internet location
How the web works provides a simplified view of what happens when you view a webpage in a web browser on your computer or phone. Show This theory is not essential to writing web code in the short term, but before long you'll really start to benefit from understanding what's happening in the background. Computers connected to the internet are called clients and servers. A simplified diagram of how they interact might look like this:
The client and server we've described above don't tell the whole story. There are many other parts involved, and we'll describe them below. For now, let's imagine that the web is a road. On one end of the road is the client, which is like your house. On the other end of the road is the server, which is a shop you want to buy something from. In addition to the client and the server, we also need to say hello to:
When you type a web address into your browser (for our analogy that's like walking to the shop):
When browsers send requests to servers for HTML files, those HTML files often contain
Real web addresses aren't the nice, memorable strings you type into your address bar to find your favorite websites. They are special numbers that look like this: This is called an IP address, and it represents a unique location on the web. However, it's not very easy to remember, is it? That's why Domain Name Servers were invented. These are special servers that match up a web address you type into your browser (like "mozilla.org") to the website's real (IP) address. Websites can be reached directly via their IP addresses. You can use a DNS lookup tool to find the IP address of a website. Earlier we used the term "packets" to describe the format in which the data is sent from server to client. What do we mean here? Basically, when data is sent across the web, it is sent in thousands of small chunks. There are multiple reasons why data is sent in small packets. They are sometimes dropped or corrupted, and it's easier to replace small chunks when this happens. Additionally, the packets can be routed along different paths, making the exchange faster and allowing many different users to download the same website at the same time. If each website was sent as a single big chunk, only one user could download it at a time, which obviously would make the web very inefficient and not much fun to use. What is a site that asks people to contribute funding to a project?Crowdfunding is the practice of funding a project or venture by raising money from a large number of people, typically via the internet. Crowdfunding is a form of crowdsourcing and alternative finance.
What does a business to consumer website use to track the items you select on a website?Websites track visitors by using technologies such as cookies, pixels, and fingerprinting to measure browsing behavior and serve personalized content.
What is a post to a microblog such as twitter?Microblogging is a short blog post designed for quick and typically direct audience interactions. These concise blogs are shared using social media platforms like Twitter or Instagram, and can include different content formats such as audio, text, images or video.
Which of the following is a microblogging service?The most popular microblogging service is Twitter, but other services such as Plurk, Tumblr, Identi.ca and Weibo are popular in other areas of the world.
