In [[computer science]] and [[computer engineering]], a '''computer architecture''' is a description of the structure of a [[computer]] system made from component parts.<ref>{{cite web|last=Dragoni|first=Nicole|title=Introduction to peer to peer computing|url=http://www2.imm.dtu.dk/courses/02220/2017/L6/P2P.pdf|website=DTU Compute – Department of Applied Mathematics and Computer Science|___location=Lyngby, Denmark|date=n.d.}}</ref> It can sometimes be a high-level description that ignores details of the implementation.<ref>{{cite book|last1=Clements|first1=Alan|title=Principles of Computer Hardware|page=1|edition=Fourth|quote=Architecture describes the internal organization of a computer in an abstract way; that is, it defines the capabilities of the computer and its programming model.
