The benefit to home routers is that all you need to do is plug them in, and they pretty much work out of the box, allowing multiple computers to use a single internet connection.

Let's say I wanted to transparently replace my standard home router with an "enterprise-style" switch. Is it possible to purchase an unmanaged switch, or does it need to be managed for features such as NAT?

There is a question that already explains the difference between managed and unmanaged switches, and brings up things like SSH access and network monitoring, but it makes no reference to basic features like serving DHCP addresses or very simple port forwarding.

Are unmanaged switches more like "brainless hubs", or do they at least contain basic features found in most home routers? By the same definition used on switches, would a standard home router be considered "managed" or not?

Your mixing things up a bit. Layer 2 switches and Layer 3 switches both function as network switches with the difference being that a Layer 3 switch has the capability of being able to perform routing functions. BUT, being managed doesn't imply Layer 3 capability. There are many, many Layer 2 managed switches that do nothing more than switch. That being said, it isn't possible to have an unmanaged Layer 3 switch, so if it's a Layer 3 switch then that implies that it's a managed switch, but take care not to infer that a managed switch implies Layer 3 functionality.

To expand on this, because it didn't directly answer your question:

An unmanaged switch cannot provide services and features like DHCP, VLAN, SNMP, QOS, etc. etc. because there's no interface or mechanism for configuring and managing those services and features. If you need those services and features then you'll need a managed switch. An unmanaged switch is essentially "brainless" in that it switches/forwards Ethernet frames from one port to another, and that's about it.

  1. Switches aren't meant to do things like DHCP, port forwarding, NAT, PPPOE, DNS, Wifi, etc... like a home router does. they are designed to switch. Some have extra features, but that is the general idea.

  2. Unmanaged switches really only just switch with no other significant features and cannot be configured to do anything else. They have no management interface.

  3. If you need home router functionality with a higher end solution you'll need some kind of appliance, like a firewall or you'll need to setup a server and configure all of those features yourself.

  4. Yes home routers are "managed"
