There
are many terms which are used widely in Computer Architecture. In this post, I
am going to discuss about some of those terms. As the actual and practical
meaning of a term may have difference. So, all should keep in mind this
terminology page in order to understand the studies of computer architecture
easily.
This website always posts about various kinds of
educational topics. Stay up-to-date with us by liking our facebook page www.facebook.com/ofuran .
