Explanation

The formula for the number of possible communication channels in a round table meeting is: n(n-1)/2.

Explanation

• When subtracting 1 GB from 18 GB, you get 17 GB.
• This is because 18 GB minus 1 GB equals 17 GB.

Explanation

A  supercomputer is a computer that performs at a higher level than a general-purpose computer 

all the world's fastest 500 supercomputers have been running Linux-based operating systems since November 20017

while 

A personal computer (PC) is a multi-purpose computer 

A mainframe computer, often known as a big iron used largely by large enterprises

Explanation

Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell,

usually consisting of a tiny capacitor and a transistor,

both typically based on metal-oxide-semiconductor (MOS) technology.

Explanation

The number of bits processed by the CPU as a unit is called Computer word

"Word size" refers to the number of bits processed by a computer's CPU in one go (these days, typically 32 bits or 64 bits).

Explanation

The execution time or CPU time of a given task is defined as the time spent by the system executing that:

the task, including the time spent executing run-time or system services on its behalf.

Explanation

The control unit (CU) coordinates the functions of a computer system.

The information stored in the memory unit (e.g. hard disk drive) is extracted and decoded 

and executed by the control unit to demand help from ALU whenever required.

CPU contains a register where the processing of arithmetic operations of data occurs.
