Processor and Internal Stuff
or
the “guts” of the computer
What’s inside the case?



All of the major
components of the
computer
The CPU chip
The memory (RAM)
What is the CPU chip and is it
any good with onion dip?




The “brains” of the
computer
Controls all of the
“processing” inside
the computer
Performs math
calculations
Also determines the
model name
Chip Naming System
All IBM compatible computers use a CPU
chip manufactured by Intel or a competitor
 As a general rule of thumb, the bigger the
chip number, the more powerful the
computer system.

– Intel 80386 chip = 386 computer
– Intel 80486 chip = 486 computer
Types of CPU Chips

8088, 8086, 80286
80386SX

80486SX
80486
Pentium
– Pentium with MMX

Speed of the chip


Chip speed is
measured in MHz
The larger the number,
the faster the chip is
– 486-25
– 486-33
– 486-100
What is RAM




Stands for Random
Access Memory
The working memory
of your computer
The size of your desk
Must have enough
space to run your
software
How much do I need?

Check the requirements for your software
– NEVER go by the minimum requirements

General rules of thumb
–
–
–
–
–
DOS programs 1- 4 MB generally
Windows 3.x - 4 - 8 MB minimum
Windows ‘95 8-16 MB minimum
Windows 98 32 MB minimum
If you will be working with many large documents, or
graphics, add more
Adding memory
Memory is added in specific increments
 You usually can’t add just 1 MB

– Normally you must double what you have
– 4 MB to 8MB
– 8 MB to 16 MB

Sometimes you can just add to what you
have, sometimes you must replace it all
