Kaizilege Karoma Storage Capacity + What to buy

Binary Did you know that all of the information that travels through your computer is based on two commands? The only data that a computer can understand is on and off / 0 and 1 (Machine Language) But, the millions of combinations of those two commands given in series are what make a computer work.

KB, MB, GB, and TB You may have seen these abbreviations many times before. Do you know what they mean? 0/1 = Bits Byte = 8 Bits Kb = kilobyte = about 1,000 bytes, MB = megabyte = about 1,000 Kb, GB= gigabyte = about 1,000 Mb TB=Terabyte = about 1,000 Gb

A Conversion Example Let’s say we can purchase one of two memory stick, one of them is 1,746 MB and the other is 1.5 GB. Which memory stick should we choose?

Processor Speed Processor speed is measured in MHz 1000 MHz = 1GHz
