Link Local Address is used for communication with in a router, if you want to communicate outside your router you need to use site local address.
The difference between a link and an interface is the protocol used.
An IPv6 device is automatically assigned a link-local address, which is a type of address that is used for communication within a local network segment. This address is generated using the device's MAC address and the prefix "FE80::/10". Link-local addresses are essential for functions such as neighbor discovery and are not routable beyond the local link.
The IPv6 prefix reserved for communication between devices on the same link is the link-local address prefix, which is FE80::/10. This range includes addresses from FE80:: to FEBF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF. Link-local addresses are used for network communication within the local subnet and are automatically configured on IPv6-enabled interfaces.

No, the source link-layer address does not define the network; it identifies the specific device within a local network. Link-layer addresses, such as MAC addresses, are used for communication within the same local area network (LAN) and are not routable across different networks. The network itself is typically defined by its IP address range or subnet, which facilitates routing between different networks.

A link is what you click on on your computer. A menu is what you get when you're at a resturaunt.

The IPv6 address that is required for other computers on a local network to communicate with each other is, the "Link-local address". The first hextet will always begin with FE80.
DNS gives out IP address for domain names (among other things) so when you type Google (see related link) into the address bar your computer will resolve that to an IP address and then go to the IP address. HTTP is a protocol for delivering webpaeges.
Their address. They may also have different values, and their sequence may matter, depending on the design of the algorithm.
Technology wise there is no such difference.
