A 56K modem card was used in the late 1990s - early 2000s to connect the laptop via a cable connected to the laptop directly to a telephone cable when "dial up internet services" were common and not the higher speed adsl or fibre optic connections that are used today, where you connect the laptop via an Ethernet cable (LAN) to an external modem or use WiFi (WLAN) to connect to a wireless router for the internet connection.

Hi @arsish
Not having one won't affect your laptop.
It is no longer used as it is outdated.
