1. How Fast is Your computer?
s1240037 Tomoya Hirota

2. Introduction
 Recent years, computer technology advance
 Today's computers faster than old computers

3. Question
 Is there a way to measure how fast a
computer?
 Yes!!

4. Answer and Attention
 We can test the speed of a computer
 But we should know a little more about
how a computer works and what it takes to
make one faster.

5. About computer
 Computer understand what we want to do
through clicks of the mouse, taps on the keyboard
etc.
 We called it input
 The exact instructions were processed by CPU
 The CPU store the result in computer’s memory

6. Multi tasking
 Also, Recent computer can multi tasking
 Therefore, operating system divide CPU’s
attention
 Computer can do the more things at the same
time
 However, the slower it might seem.

7. Project and conditions
 In this project, computer measure the time
to need to calculate four difference
calculation
 You will test the speed in each of these
operations for four different ways of storing
numbers

8. We need to know those
 Benchmarking
 Inputs
 Software
 Central processing unit (CPU)
 Hardware
 Memory
 Multitasking
 Operating system
 Data types(Integers, Long Integers, Floating points, Double-precision floating
points)
 Bits

9. Correspondence
 Thereby, people can get useful information
 Therefore, Programmer develop the
program which is executed rapidly
 But we need to warn it is hard for recent
multitask operating system to measure the
execution time of any single process

10. Main Question
 Which data type do you predict the test computer will
process most quickly? Which do you predict the computer
will process most slowly?
 How do you measure the speed of computer operations?
 Why are older computers slower than newer ones?
 When manufacturers sell a computer, they list the
"processor speed." What does this mean?
 Why does it matter how much memory a computer has?

11. Materials and Equipment
 Computer with web browser and Internet
access
 Calculator or spreadsheet program, such as
Excel, for analyzing data
 Lab notebook
 Graph paper

12. Procedure No.1
 First, we should do your background research
 Also, We become to answer the questions from
the background section
 Create a data table, like this picture, in your lab
notebook or spreadsheet program

13. Procedure No.2
 Use the web page to measure the execution
time for each of the mathematical
operations using each of the data types

14. Procedure No.3
 Calculate the average processing time for each
combination
 Make four bar graphs to examine if the amount of
time the computer needed to do a single type of
mathematical operation changes with different
data types

15. At last
 In this way, we can measure how fast a computer
 If we measure how fast a computer, we can live a
comfortable PC life
