Using of Layer Model

1)
THE USING OF LAYER MODEL:
The following steps for the order and delivering of pizza. The following necessary requirement for this
order of pizza is guest, host, order clerk, cook pizza.
The block diagram layers of the order have shown in figure 1.
a)
The guest user has search pizza details on GOOGLE. The guest has got a telephone number and makes to
call to that number. Now the pizza centre telephone number has rung, the host gets received the
telephone by the guest. The conversation has stared between guest and host. Now, the guest asks about
the pizza menu, the host explained about pizza and its cost.
b)
The host takes order form guest, and take address and telephone numbers details from the guest. Now,
the host tells about payment methods to the guest, payment takes while delivering.
c)
The host connected the call to order clerk, and give complete order information to order clerk.
Now, the order clerk gives information to pizza cook.
d)
Now, pizza cooks to prepare for pizza, according to order details. The pizza cook gives cooked pizza to
order clerk for packing. Now, the order clerk makes to attached payment receipt and address of the
host.
e)
The delivery van comes and picks the pizza from the pizza centre, the delivery boy delivered to the
specified address which attached in a pizza box and collects the amount from the guest.
2)
THE USING OF LAYER MODEL:
The block diagram of the situation and describe the interaction of each level as shown in figure 2.

a)
Both Chinese and French ministers speak each other through a translator.
b)
I suppose The Chinese prime ministers speak with the French prime ministers, the message pass through
Chinese translators and vice versa.
c)
The Chinese translator passes through a message to the French translator through the telephone line.
e)
Hence, therefore the French translator passes the message to The French prime ministers and vice
versa.
