Briefly describe Gigabit Ethernet.
What will be an ideal response?
Gigabit Ethernet (1000BaseX) is the next iteration of Ethernet, increasing the speed to 1000 Mbps. IEEE 802.3z includes 1000BaseSX over multimode fiber, 1000BaseLX over single-mode fiber, and 1000BaseCX over balanced-copper cabling. The IEEE 802.3ab standard defines the more common 1000BaseT configuration over all four pairs of UTP. Although Gigabit Ethernet can work in half-duplex mode through hubs, this is not typical. Almost all applications of the standard are full-duplexed through switches. 10 Gigabit Ethernet (10GBaseX, 10GbE or 10GigE) is the fastest of the Ethernet standards. This relatively new standard is ten times faster than Gigabit Ethernet. 10 Gigabit Ethernet is full-duplex only, through switches.

What is the output of the following function and function call?
void calculateCost(int count, float& subTotal, float taxCost); float tax = 0.0, subtotal = 0.0; calculateCost(15, subtotal,tax); cout << "The cost for 15 items is " << subtotal << ", and the tax for " << subtotal << " is " << tax << endl; //end of fragment void calculateCost(int count, float& subTotal, float taxCost) { if ( count < 10) { subTotal = count * 0.50; } else { subTotal = count * 0.20; } taxCost = 0.1 * subTotal; } a. The cost for 15 items is 3.00, and the tax for 3.00 is 0.30; b. The cost for 15 items is 0.00, and the tax for 3.00 is 0.00; c. The cost for 15 items is 0.00, and the tax for 3.00 is 0.30; d. The cost for 15 items is 3.00, and the tax for 3.00 is 0.00;
