Chip Naming SystemChip 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 ChipsTypes of CPU Chips

8088, 8086, 80286 80386SX 80386 80486SX 80486 Pentium

– Pentium with MMX Pentium Pro Pentium II Pentium III Pentium IV

Speed of the chipSpeed 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 RAMWhat 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?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 memoryAdding 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
