Week 2

Digital logic corresponds to

• the circuit level, gates and wires

• the hardware algorithm described in assembly

• the instruction set available for each architecture

• the operating system behind user applications

Hardwired control does not have as characteristic

• Flexibility

• Smaller footprint

• Faster design

• Fixed logic

What is "computer architecture"?

• The study of transistors

• The study of how the designer should see the system

• The study of memories

• The study of how components are seen by the user

Answer explanation

The study of how to design data types, features and operations of a computer system that are visible to the programmers is called computer architecture

Each computer implements a different ISA, regardless of the technology and instruction set

• TRUE

• FALSE

The interface between HW and SW is given by

• ISA

• User application

• Digital Logic

• VLSI

The concept of stored computer was introduced by Alan Turing. His machine allowed us to do

• As much computation as the memory (tape) allows

• Simple computations only

• Any type of computation

• None of the answers

The memory management is implemented in the system software layer. Another feature of such layer is implement

• Low-level Instructions

• Local storage (registers)

• Datapath

• Device drivers

What is the main bottleneck of Von Neumann Architecture?

• Low processing power

• Complex design with large ISA

• Bus interference

• Small memory

The layer that provides services to another software is

• Digital logic

• System Software

• Assembly Code

• Control

The 7 levels of computer hierarchy are:

• VLSI, Vacuum, Transistor, IC, ULSI, OS and Java

• C, C++, Assembly, Java, PHP, Python and Ruby

• Digital Logic, Control, Machine, System Software, Assembly language, High-level Language and Operating systems

• Digital Logic, Control, Machine, System Software, Assembly language, High-level Language and user applications
