System Architecture

1. cache speed

   • The "raw" speed of the cache is the speed of the RAM chips used to make it. Caches are normally made from static RAM chips (SRAM), unlike main system memory which is made from dynamic RAM (DRAM). The short version of the difference between the two, is that static RAM is faster but also more expensive.

2. number of cores

   • This total number of logical processors is the number of physical CPUs multiplied by the number of cores per CPU. In the example below we have each physical CPU containing 4 cores. There are 2 physical CPUs on the system so 2 CPUS X 4 cores each CPU = 8 total cores.

3. clock speed

   • the operating speed of a computer or its microprocessor, expressed in cycles per second

4. Binary

   • All computer data is represented using binary, a number system that uses 0s and 1s. Binary digits can be grouped together into bytes.
   • hexadecimal
     • Hexadecimal (or hex) is a base 16 system used to simplify how binary is represented. A hex digit can be any of the following 16 digits: 0 1 2 3 4 5 6 7 8 9 A B C D E F. Each hex digit reflects a 4-bit binary sequence.
     • denary
       • Denary. Denary, also known as "decimal" or "base 10," is the standard number system used around the world. It uses ten digits (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) to represent all numbers. Denary is often contrasted with binary, the standard number system used by computers and other electronic devices.27 Jan 2015

5. von neumann

   • The von Neumann architecture, which is also known as the von Neumann model and Princeton architecture, is a computer architecture based on that described in 1945 by the mathematician and physicist John von Neumann and others in the First Draft of a Report on the EDVAC.
