Pentium II

Pentium III

Pentium 4 or Pentium M

Pentium 5

200 to 400 MHz

500 MHz to 1.2 GHz

1.4 to 3.2+ GHz

5 GHz to 7 GHz

MMX refers to MultiMedia eXtension technology, or the ability to play video or audio files on a computer.

This technology was introduced in the Pentium II processors, and continues today. The Pentium M is a newer type of microprocessor designed for notebooks. The M stands for mobile and provides a number of memory management tools for notebooks.

1-5 The Memory

In order for a computer to be able to store information, either about its configuration or data files, the computer needs to have memory chips installed. Memory is measured in bytes; in very simple terms, (one byte is equal to one character) . computers were developed using a numbering system of 1 s and 0s. These two unique numbers are designed to represent the charged or uncharged nature of electricity. This is known as the binary system. These two digits make a bit and eight bits make one byte.

With the advancement of computer technology, the storage capacity has grown

1 Kilobyte = 1,028 Bytes or 1 Thousand Bytes

1 Megabyte = 1,028,000,000 Bytes or 1 Million Bytes

1 Gigabyte = 1,028,000,000,000 Bytes or 1 Gillion Bytes

1 Terabyte = 1,028,000,000,000,000 Bytes or 1 Trillion Bytes
