Answer:
4 * 8 * 6 = 192
Explanation:
First menu = 4 selections
second menu = 8 selections
third menu = 6 selections
we need to find how many configuration can the game be played, we just here multiply all the selections and find the answer
4 * 8 * 6 = 192
Answer:
Physical / Data link layer
Explanation:
If two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, the data would be transmitted if the network is clear but if the network is not clear, the transmission would wait until the network is clear.
The Open Systems Interconnection model (OSI model) has seven layers each with its own function.
The physical layer is the first layer responsible for data transmission over a physical link. The data packets are converted to signals over a transmission media like ethernet cable.
The data link layer is the second layer in the OSI layer responsible for transmission of data packets between nodes in a network. It also provides a way of detecting errors and correcting this errors produced as a result of data transmission.
Answer:
ii. break
Explanation:
In Computer programming, a loop can be defined as a sequence of instructions that are executed repeatedly until a specific condition is true or for a certain number of times.
This ultimately implies that, a loop is a programming structure that continually repeats a sequence of instructions until a specific condition is true (met) or for a definite number of times.
Basically, there are three (3) main types of loop in programming and these includes;
I. For loop.
II. While loop.
III. Repeat.
Since loops continually repeats a sequence of instructions until a specific condition is true (met), it is a best practice to ensure that the loop breaks at some point to avoid an infinite loop. An infinite loop typically causes a software program to crash.
Thus, the break command is used by programmers to prevent an infinite loop or terminate a current loop immediately.
Hence, the command to get out of the loop is break.
Answer:
a) 500 Kbps b) 64 sec c) 320 sec
Explanation:
a) We define the throughput of a network, as the actual maximum transmission rate that the network is able to deliver, which in this case is equal to the lowest transmission rate of any of the links that the traffic must go through:
R1 =500 kbps
b) If the file size is given in bytes, and we have the throughput in bps, we need to convert to bits first, as follows:
4*10⁶ bytes * (8 bits/byte) = 32*10⁶ bits.
The time needed to transfer the file, will be given by the quotient between the file size and the throughput, as follows:
t = 32*10⁶ bits / 500*10³ bits/sec = 64 sec
c) If the transmission rate R2 is reduced to 100 kbps, R2 becomes the lowest transmission rate in the network, so it becomes the new throughput.
So, the time needed for the same file to be transferred to host B is as follows:
t= 32*10⁶ bits / 100*10³ bits/sec = 320 sec
