2. History (1)
ALTAIR that is the world’s first personal computer was put on the
market in 1975.
The computer that adopt 32-bits was put on the market in 1987.
The world’s first laptop was put on the market in 1989.
3. History(2)
The world’ first personal computer that adopt 64-bits was put on the
market in 2003.
Windows 7 released in 2009.
iPhone4S released and sold explosively in 2011
7. What is making computer late?
1. CPU is old
2. Lack of RAM
3. Crashed due to overheating
8. How Fast is Your Computer ?
There are many ways that make computer faster.
9. CPU
The number of cores
The more cores there are in CPU, the faster computers
process
A CPU that have Twenty two cores was developed in
recent years.
10. bits
The higher number of bit is, the larger CPU use
memory and data so computer can process
many programs at the same time.
11. Moore’s Law
Moore who is one of the founders of Intel said “The
number of transistor in semiconductor integrated circuit
increase twofold every two years”.
In fact, semiconductor technology continue to develop
12. Benchmarking
We can know product performance
We can compare product performance and choose product
from benchmark test of processing speed access speed and so
on.
13. RAM
When computer process and calculate, CPU use main
memory to store many data.
The larger capacity, the more CPU can store data so
computer can improve the efficiency of working in
processing and calculate.
14. Multitasking
It is a way of processing many programs at the same time.
In fact, computer separate programs with task and pursue
while changing task.
15. Conclusion
Programmers use measurements to develop programs that will run in
less time.
We can know product performance from measurements of benchmark
test
