The hertz (symbol: Hz) is a measure of frequency, informally defined as the number of events occurring per second. It is the basic unit of frequency in the International System of Units (SI), and is used worldwide in both general-purpose and scientific contexts. Hertz can be used to measure any periodic event; the most common use for hertz is to describe frequency of rotation, in which case a speed of 1 Hz is equal to one cycle per second.
giga is the prefix for billion.

2.2 GHz is the measurement of processing power of the CPU on a personal computer (PC) GHz stands for Gigahertz. A Gigahert is 1000 Megahertz of processing power.
There is no such thing. A giga*hertz* is 1 000 000 000 ("one billion") hertz, i.e. 1 000 000 000 electrical or electromagnetic cycles in a second.
A million machine cycles per second is equivalent to 1 MHz (megahertz). This measurement is commonly used to quantify the processing speed or clock speed of a computer's central processing unit (CPU). A higher MHz value generally indicates a faster CPU.
Speed(s): Hz (Hert or Hertz). 1 Hz is equal to 1Hz. 1,000 Hz = 1 Mega Hert or 1 MHz. 1,000 MHz = 1 Gigahert (GHz). Processors today usually run at speeds of around 2.4 GHz or higher. Not to mention that some are Mult-Threaded and Multi-Cored. Memory: B (Byte or Bytes). 1 Byte = 1 Byte. 1,000 Bytes = 1 Kilobyte or 1KB. 1,000KB = 1 Megabyte or 1MB. 1,000 MB = 1 Gigabyte or GB. 1,000 GB = 1 Terabyte or 1 TB. 1,000,000,000,000 (1 Trillion) Bytes = 1 Terabyte/1TB. Transfer Rate(s): Bps (Bit or Bits Per Second) 1 Bps = 1 Bps. 1,000 Bps = 1 Kilobits per second or 1 Kbps. 1,000 Kbps = 1 Mbps (Megabits Per Second). 1,000 Mbps is 1 Gbps (Gigabit Per Second.)
