6) What is an IP address?
7) What is the CPU clock speed and how it is measured?

Answer 1

Answer 5
**********
An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs. In addition to ALUs, modern CPUs contain a control unit (CU).

IP address is unique number which identifies the computer and comminicate with that ip address along with network support.

Size of IP address is 32bit or 4byte. eg xxx.xxx.xxx.xxx format
192.168.1.1

IP address are diveded into 5 classes but 3 classes are used.
CLASS A 0 to 127
CLASS B 128 to 191
CLASS C 192 to 223

so ip addresses are from these three classes only other two classes are for research and militery purpose.
Answer 7

clock speed shown by MHz or GHz. The unit of estimation utilized to degree a computer’s clock speed is called a hertz (Hz). This indicates one cycle per moment and measures a clock’s speed. In computer clock speed, one hertz is identical to one tick per moment. A computer’s clock speed is ordinarily measured in MHz (megahertz) or GHz (gigahertz). A megahertz is rise to to one million ticks per moment whereas one gigahertz is rise to to one billion ticks per moment. A computer with the clock speed of 600MHz runs at 600,000,000 cycles per moment, whereas a 2.0GHz computer runs at 2,000,000,000 cycles per moment.
