THE LANGUAGE OF COMPUTERS
![Page 8: Welocme to Training on Computer Fundamentals](https://reader035.vdocuments.mx/reader035/viewer/2022081514/568148e2550346895db5fc6c/html5/thumbnails/8.jpg)
Binary Numbers 1 and 0 ‘s
Computers speak binary. Binary language consists of combinations of 1's and 0's that represent characters of other languages (in our case the English language). Don’t make the mistake of thinking that little 1's and 0's are running around inside of the computer. We humans prefer to think of 1's and 0's because it’s easier than visualizing positive and negative current flows or open and closed circuits which is what actually happens inside computers. A combination of eight bits represents one character in our language. One character in our language (eight bits) is referred to as a byte. (For example: 01000001 is a byte that represents an uppercase A; each 1 or 0 is a bit.)

Binary Numbers
Kilobytes, Megabytes, and Gigabytes
If you understand that a byte is one character in our
language, you’ve got it made because:
1000 bytes = 1 kilobyte
(1,000 characters = 1 kilobyte)
1,000,000 bytes = 1 megabyte
(1,000,000 characters = 1 megabyte)
1,000,000,000 bytes = 1 gigabyte (1,000,000,000
characters = 1 gigabyte)

Ram – Random Access MemoryRam is the memory used by the computer to run programs.The amount of Ram available will determine how fast a program will run and how many windows can be open at one time.Ram memory is considered Volatile because it disappears when the power is turned off.
