Hi,
Pentium 4 refers to the laptop processor.
Intel Pentium 4 is a family of high-performance microprocessors that
succeeded Pentium III family. Pentium 4 CPUs are based on new
NetBurst micro-architecture, which differed significantly from
P6 micro-architecture used in
Pentium
II/
Pentium
III
microprocessors. As an overall CPU performance is proportional to
its frequency and its efficiency, to achieve better performance
levels many micro-architectures, including P6, strike a delicate
balance between faster CPU frequencies and improved efficiency. The
NetBurst microarchitecture used different approach - it attempted to
improve performance primarily by increasing CPU frequency, often at
at the expense of efficiency. One of key elements in this approach
was "Hyper-Pipelined Technology" - 20-stage pipeline (not counting
decoder stages), that was significantly longer than in previous
generation of Pentium processors.
The rest of the components in the laptop are used in many other laptops. For example hard drive, memory and graphics.
Regards.
