Disk fragmentation occurs when a file is broken up into pieces to fit on the disk. Because files are constantly being written, deleted and resized, fragmentation is a natural occurrence. When a file is spread out over several locations, it takes longer to read and write.
Answer:
d. All statements are correct.
Explanation:
Network Access Point (NAP), also known as an Internet Exchange Point (IXP) enables service provider Internet Protocol (IP) networks to interface one another through peering agreements, which enable the free flow of IP traffic (packets) between internet service providers (ISP). The NAP/IXP comprises of high-speed switching facilities for transferring packets from one internet service provider's lines to another’s, thereby making them function as a single entity.
Also, by having a robust physical facility, it provides connectivity from the physical to network layers of the OSI reference model.
With NAP/IXP, Border Gateway Protocol (BGP) is implemented to share routing data between the ISP networks.
The potential benefits of NAP/IXP systems are,
- Ensures reduced latency.
- Routing bandwidth and efficiency is improved.
- High-speed data transfer.
- Fault tolerant.
Answer: It does not guarantee an optimal solution
Explanation: Simulation is the property presenting the the real world behavior in the form of a model. The model is made up of mathematical equation and functions .This process is basically used for knowing the phenomena which are less predicted and rare to happen in real life and to find the result of that this model is used.
This process does not provide a precise output so there is no optimization present that is it does not provide the exact answer but a number of possible outcomes for a problem.
Answer:
Jason = <span>20yrs.old</span>
Mandy = <span>15yrs.old</span>
Explanation:
Let
J = Jason's age
M = Mandy's age
<span>J+M=35</span> ..... eq. 1
<span>J−10=2<span>(M−10)</span></span> ..... eq. 2
From eq. 1
<span>J=35−M</span>
Substitute this in eq. 2.
<span><span>(35−M)</span>−10=2<span>(M−10)</span></span>
<span>35−10−M=2M−20</span>
<span>35−10+20=2M+M</span>
<span>45=3M</span>
<span><span>453</span>=<span><span>3M</span>3</span></span>
<span>15=M</span>
<span>J=35−M</span>
<span>J=35−15</span>
<span>J=<span>20</span></span>
