(a) Two-wire cable: Is a transmission cable that consists of two parallel copper wires separated by a dielectric material.
They are used for low speed transmissions. They are heavily affected by cross-talk transmission impairment.
(b) Twisted pair cable: Is a transmission cable that consists of two copper wires entwined around each other in a spiral pattern so as to reduce electromagnetic interference.
There are two types of twisted pair cables namely:
(i) Unshielded Twisted pair (UTP).
(ii) Shielded Twisted Pair(STP).
(c) Coaxial cables: Is a transmission cable consisting of inner copper wire surrounded by insulation then a grounded shield of braided wire to minimize electromagnetic and radio frequency interference.
There are two types of coaxial cables namely:
(i) Thinnet.
(ii) Thicknet.
(d) Fibre optic cables: Is a transmission cable made up of strands of glass fibres that use pulses of light to send data signals from source to destination.
There are two types of fibre optic cable namely:
(i) Single mode fibre.
(ii) Multimode fibre.

1.Create a funtion called sroot() in C++ language that returns the square root of its argument.Overload sroot() three ways: have it return the square root of an integer, a long integer, and a double.(use the sqrt() standard library fubction)
2.Create a function called min() in C++ language that returns the smaller of the two numeric arguments used to call the function.Overload min() so it accepts characters, integers, and doubles as arguments.
3.Create a function called sleep() using C++ language that pauses the computer for a number of seconds specified by its single argument.Overload sleep() so it can be called with an integer.Demonstrate that your function work by including them in a short program.
4.Write a C++ program using the I/O to input two integers from the keyboard and then display the result of raising the first to power of the second.Example if a user enters 2 and 4, the result is 2^4, or 16
