Page 1 of 5 ITEC 255 – Computer Organization & Architecture / TUTORIAL / Lecture 2 Q1. What is the difference between Computer Architecture and Computer Organization ? Give examples. A1. Computer Architecture refers to those attributes of a system that have a direct impact on the logical execution of a program (e.g., instruction set, the number of bits used to represent various data types like numbers, characters, etc., I/O mechanisms, and techniques for addressing memory) where as Computer Organization refers to the operational units and their interconnections that realize the architectural specifications. Organizational attributes include those hardware details that are transparent to the programmer, such as control signals, interfaces between the computer and its peripherals, and the memory technology used. Q2. Consider the current trend in the production of PCs and/or Laptops, what roles do architecture and organization of these computers play in attracting buyers from different walks of life? Exemplify your comments. A2. Both (architecture and organization) have become increasing important for both novice and professional computer users. Certain factors like light weight, large storage capacity (in gigabytes), speed (in gigahertz), connectivity (Bluetooth, USB) and the like have made computer manufacturers to pay heed to consumerism. Similarly, the exterior of the computers have become equally important. It would be a prestige to possess Apple’s MacBook Pro [3] . Even the pricing of these computers play an important role in attracting buyers. An average buyer would prefer to pay a reasonable price for the latest devices. Q3.
