Fetching pages is an important part of web development. It refers to the process of retrieving a requested page from a server and displaying it in the browser window. Fetching pages can be done using various methods such as HTTP, FTP, or other protocols depending on what type of content is being retrieved.

The most common method used for fetching pages is HTTP which stands for Hypertext Transfer Protocol and allows web browsers to request information from servers over the internet.

When fetching a page, there are several steps involved including establishing a connection with the server, sending out requests for data, receiving responses containing HTML code or other types of data (such as images), parsing that data into usable formats like JavaScript objects or XML documents before finally rendering it in an appropriate format so that users can see it displayed properly on their screens.

This entire process occurs very quickly when compared to traditional methods such as manually downloading files from websites via FTP clients which take considerably longer due to having more steps involved in transferring files between computers across networks rather than just connecting directly through one protocol like HTTP does.

In today’s modern world wide web applications have become much faster thanks largely due this improved methodologies involving fewer middle-man processes between user requests and response delivery times.

Overall, fetching pages has come along way since its early days where manual downloads were required instead now we have direct access with near instantaneous response rates all thanks advances made within fields computer science networking technologies allowing us get exactly what want quicker easier manner then ever before!
