Answer:
D. MAN
Explanation:
A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings. Some of the network devices or equipments used in a local area network (LAN) includes an access point, personal computers, a switch, a router, printer, etc.
On the other hand, a metropolitan area network (MAN) is formed by an aggregation of multiple local area network (LAN) that are interconnected using backbone provided by an internet service provider (ISP). A metropolitan area network (MAN) spans for about 5 kilometers to 50 kilometers in size.
Basically, a metropolitan area network (MAN) spans across a geographic area such as a city and it's larger than a local area network (LAN) but significantly smaller than a wide area network (WAN).
In conclusion, the network type that the patrol services of a city's police department would most likely use is a metropolitan area network (MAN).
Answer:
Whether a traffic light is green, yellow or red
Explanation:
Boolean variables are variables that can either take one out of two options at any given instance.
Analyzing the given options
1. Elevator:
Possible Directions = Up or Down; That's two possible values
But it can only move in one direction at a given instance.
<em>This can be represented using Boolean</em>
2. Traffic Light:
Possible Lights = Green, Yellow or Red
That's three options.
<em>This can be represented using Boolean</em>
<em />
The last two options can be represented using Boolean because they have just two possible values
<em>Hence, option (B) answers the question</em>
Three-phase electric power is a common method of alternating current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads.
A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a given amount of electrical power. Polyphase power systems were independently invented by Galileo Ferraris, Mikhail Dolivo-Dobrovolsky, Jonas Wenström, John Hopkinson and Nikola Tesla in the late 1880s.
Answer:
Check the explanation
Explanation:
Assuming Cust_code is unique for every customer.
Query :
SELECT * FROM CUSTOMER WHERE CUST_STATE= "AL" GROUP BY CUST_CODE HAVING LARGEST INVOICE = MAX(LARGEST INVOICE) OR (LARGEST INVOICE =0 and INV_DATE IS NULL);
Answer:
process
Explanation:
Given
The program in python
Required
What does line 2 represents
The line 2 of the program is: weight = float(strWeight)
And what it does is that it converts the input weight from string to float after the user supplies value for strWeight
This conversion not input, output, neither is it planning. It is process because according to the program it prepares variable weight to be printed as float on line 3
