+# Chipset and controllers
+
+A **controller** is simply a circuit that controls a process. The **chipset** is a combination of controllers placed on the same piece of silicon.
+
+The chipset manages the data flow between the different components that comprise the [motherboard](/Hardware/Motherboard.md): processor, [memory](/Hardware/Memory/RAM_types.md), [harddisk](/Operating_Systems/Disks/What_are_disks.md) and peripherals. 
+
+Buses run in and out of the chipset into these key motherboard components. The main chipset is a kind of junction that sits between the memory and CPU through which the [system bus](/Hardware/Bus.md#system-bus) passes. 
+
+The chipset is sometimes called the "glue" or "traffic controller" of the motherboard or _an intelligent intersection of buses_.

+# The role of memory in computation
+
+The following steps outline the way in which memory interacts with the processor during computational cycles, once the [bootstrapping](/Operating_Systems/Boot_process.md) process has completed and the OS kernel is itself loaded into memory.
