+# Socket Module
+
+## Definition
+
+A network socket is an internal endpoint for sending or receiving data within a node on a computer network.
+
+In practice, socket usually refers to a socket in an Internet Protocol (IP) network, in particular for the **Transmission Control Protocol (TCP)**, which is a protocol for *one-to-one* connections.  
+In this context, sockets are assumed to be associated with a specific socket address, namely the **IP address** and a **port number** for the local node, and there is a corresponding socket address at the foreign node (other node), which itself has an associated socket, used by the foreign process. Associating a socket with a socket address is called *binding*.
+
+## Socket Creation & Connection
+
+```python
+import socket
+
+# socket over the internet, socket is a stream of data
+socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+
+socket.connect = (("URL", port: int))  # connect to socket
+socket.close()  # close connection
+```
+
+## Making HTTP Requests
+
+```python
+import socket
+HTTP_Method = "GET http://url/resource HTTP/version\n\n".encode()  # set HTTP request (encoded string from UTF-8 to bytes)
+socket.send(HTTP_Method)   # make HTTP request
+
+data = socket.recv(buffer_size)  # receive data from socket
+decoded = data.decode()  # decode data (from bytes to UTF-8)
+```
