I played Uplink: Hacker Elite awhile back. One part of the game was that the in-game hacking software you could download had to be managed. One piece of software could take up 4 continuous slots of your computer “memory,” and I don’t think you could move it after installation without buying a piece of software that allowed movement, but you could delete it. Another could take up 2 continuous slots, another 6. I thought this was just a cool inventory system.
A decade later, nope. This is really part of how computers store stuff, including software, in memory. Aside from the fact that our modern computers do move stuff in memory without you having to buy something special to do it.
