Answer:
b) Single source shortest path
Explanation:
These are the options for the question
a) All pair shortest path
b) Single source shortest path
c) Network flow
d) Sorting
Dijkstra's algorithm is algorithm by
Edsger Dijkstra arround the year 1956, this algorithm determine the shortest path, this path could be between two nodes/vertice of a graph.
The steps involves are;
✓setting up of the distances base on the algorithm.
✓ calculation of the first vertice up to vertice adjacent to it
✓The shortest path result.
It should be noted that maximum number of times the decrease key operation performed in Dijkstra's algorithm will be equal to Single source shortest path.
Answer:
Modern (i.e 386 and beyond) x86 processors have eight 32-bit general purpose registers, as depicted in Figure 1. The register names are mostly historical. For example, EAX used to be called the accumulator since it was used by a number of arithmetic operations, and ECX was known as the counter since it was used to hold a loop index. Whereas most of the registers have lost their special purposes in the modern instruction set, by convention, two are reserved for special purposes — the stack pointer (ESP) and the base pointer (EBP).
For the EAX, EBX, ECX, and EDX registers, subsections may be used. For example, the least significant 2 bytes of EAX can be treated as a 16-bit register called AX. The least significant byte of AX can be used as a single 8-bit register called AL, while the most significant byte of AX can be used as a single 8-bit register called AH. These names refer to the same physical register. When a two-byte quantity is placed into DX, the update affects the value of DH, DL, and EDX. These sub-registers are mainly hold-overs from older, 16-bit versions of the instruction set. However, they are sometimes convenient when dealing with data that are smaller than 32-bits (e.g. 1-byte ASCII characters).
When referring to registers in assembly language, the names are not case-sensitive. For example, the names EAX and eax refer to the same register.

Answer: This is a python code
def lightyear():
rate=3*100000000 //speed of light
seconds=365*24*60*60 //number of seconds in 1 year
return str((rate*seconds)/1000)+" km" //distance=speed x time
print(lightyear()) //will print value of light hear in kilometers
OUTPUT :
9460800000000.0 km
Explanation:
In the above code, there is a variable rate, which stores the speed of light, i.e. distance traveled by light in 1 second which is in meters. Another variable is seconds, which store the number of seconds in 1 year, which is no of days in 1 year multiplied by the number of hours in a day multiplied by the number of minutes in an hour multiplied by the number of seconds in a minute. Finally, distance is speed multiplied by time, so distance is printed in kilometers and to convert distance in kilometers it is divided by 1000.
Answer:
B. displaying a list of all available commands within the current mode*
D. determining which option, keyword, or argument is available for the entered command*
Explanation:
Cisco IOS are known for using Command line interface(CLI) that allows execution of certain commands
Cisco system make use devices such as router, switch and others. All these Commans comes with privileged levels that gives access to user that have privilege to access between level 0 and 15.
It should be noted that two functions that are provided to users by the context-sensitive help feature of the Cisco IOS CLI are ;
✓displaying a list of all available commands within the current mode
✓ determining which option, keyword, or argument is available for the
