3.0GHz: This is the clock speed of the processor, indicating how many cycles it can execute per second, measured in gigahertz (GHz).
4MB: This refers to the size of the processor's cache memory, which is used to store frequently accessed data for quicker retrieval. In this case, it has a 4 megabyte cache.
400MHz FSB: FSB stands for Front Side Bus, which is the data transfer rate between the CPU and the rest of the system. This indicates that the processor has a 400 megahertz front side bus.
XEON: This denotes the processor's product line. Xeon processors are typically designed for servers and workstations, offering high performance and reliability.
With Heat Sink: This indicates that the processor comes with a heat sink, which is a passive cooling device attached to the processor to dissipate heat generated during operation.
