Lesson 11 - Measuring Memory
1 bit The amount of storage space needed to hold either a 1 or a 0 in memory (binary numbering). 1 byte 8 bits, this is the amount of storage space needed to hold one character (letter, number, symbol, space etc.). 1 kilobyte (k) 1024 bytes. This can store several paragraphs of text. 1 Megabyte (Mb) 1024k. This can store enough text for a sizeable book. 1 Gigabyte (Gb) 1024Mb. 1 Terabyte (Tb) 1024Gb. RAM frequency is measured in MHz and usually immediately follows the DDR version in the RAM spec. For example, 8GB DDR4-2400 RAM is running at a frequency of 2400MHz. Frequencies of RAM typically range from 800MHz in older DDR2 modules up to 4200MHz in DDR4. Current gen DDR4 modules start at 2133MHz Faster RAM speeds allow your processor to access the data stored in the hard drive quicker, giving your system a boost in processor performance
