During that time, the various elements that make up the Internet have made great progress in a wide range of layers, from hardware to software.\n\nHowever, in order to construct a system that can make use of these advances, it is essential to have a deep understanding of each component of the increasingly complex networks. In addition, the scale and form of individual networks and the systems provided on them are expanding, and the areas in which these advances can be utilized are increasing.\n\nIn light of these current conditions, the goal of Arch is to provide proposals that contribute to real-world systems based on a broad and deep understanding of \"Computer Architecture\".",
