1.What does it mean that web sockets are bidirectional? Why is this useful?
It means that they move data from a server to a client therefor it must be handled on both sides. This is useful because you can continuously transmit data on the same connectionsouce
2.Does socket.io use HTTP? Why?
Yes, because it uses an HTTP request, for example the local host address to create new endpoint/namespaces to transmit data between clients and server.
3.What happens when a client emits an event?
When a client emits an event, it travels to a specific endpoint in the server where there is a listener and events/data can be re-emitted.
4.What happens when a server emits an event?
When a server emits an event, it can either broadcast data globally or to a specific client.
5.What happens if a client “misses” an event?
If a client misses an event it will be ignored.source
6.How can we mitigate this?
Have events run continuously until they are handled using a sort of interval?Not sure.
Socket - an endpoint up on a server with a port number.
Web Socket - a socket on the client side.
Socket.io - a js library that allows data transmission between a server and client.
Client - the web browser where requests from a user are sent to the server
Server - a program that connects to, receives and sends information to the client
OSI Model - Open Systems Interconnection Model/framework that translates telecommunication.source
TCP Model - A more concise/specific version of the OSI modelsource
TCP - Transmission Control Protocol
UDP - User Datagram Protocol, send packets of data over the network.
Packets - Holds small amounts of data sent through UDP.
