4MB RAM card By default, in Ubuntu, we usually create a swap partition. Back in the day of 4MB RAM cards this made total sense, as the ration of RAM to disk space, was still very low. Things have changed since. Server, desktop, embedded systems have migrated to newer generations of both RAM and persistent storage. On the high performance side of things we see machines with faster storage in the form of NVMe and SSD drives. Reserving space for swap on such storage, can be seen as expensive and wasteful. This is also true for recent enough laptops and desktops too. Mobile phones have substantial amounts of RAM these days, and at times, coupled with eMMC storage - it is flash storage of lower performance, which have limited number of write cycles, hence should not be overused for volatile swap data. And there are also unicorns in a form of high performance computing of high memory (shared memory) systems with little or no disk space. Today, carving a partition and reserving twice...
Thank you for your support. Talked to parents, relatives and friends. I will survive and rock =)
