Dokumen tersebut membahas sejarah perkembangan komputer mulai dari asal usul, tokoh-tokoh penting, generasi, hingga komponen sistem komputer modern. Komputer berawal dari upaya untuk menyelesaikan perhitungan secara manual, mesin hitung mekanik, hingga berkembang menjadi komputer digital berbasis chip yang digunakan saat ini.
The separation between the CPU and memory leads to what is known as the von Neumann bottleneck . The throughput (data transfer rate) between the CPU and memory is very small in comparison with the amount of memory. In modern machines, throughput is very small in comparison with the rate at which the CPU itself can work. Under some circumstances (when the CPU is required to perform minimal processing on large amounts of data), this gives rise to a serious limitation in overall effective processing speed. The CPU is continuously forced to wait for vital data to be transferred to or from memory. As CPU speed and memory size have increased much faster than the throughput between the two, the bottleneck has become more and more of a problem.
