Answer: star topology.
Explanation:
The layout of the way how the computers in a netword are interconnected is called network tipology.
Some types of network topologies are:
1) Point-to-point tipology: all the computers are connected to each other directly (computer-to-computer, in pairs, this is a direct link between each two computers).
2) Bus topology: all the nodes (computers or server) are connectect to a maing cable.
3) Star topology: all the computers are connected to a central computer or server which is called central hub. This is the layout described in the question.
4) Ring topology: the computers are connectec in a circular path; each computer is connected to the next computer.
5) Mesh: every computer is connected to every other computer.
Complete Question:
Fill in the missing step in the following deadlock situation. Two users from the local board of education are each running a program (P1 and P2), and both programs will eventually need two DVD drives to copy files from one disc to another. Only two DVD-R drives are available and they’re allocated on an “as requested” basis. Soon the following sequence transpires:
1. P1 requests drive 1 and gets it.
2. ____
3. P1 requests drive 2 but is blocked.
4. P2 requests drive 1 but is blocked.
a.P1 requests drive 2.
b.P2 requests drive 2 and gets it.
c.P2 requests drive 1 but is blocked.
d.P1 releases drive 1.
Answer:
Soon the following sequence transpires:
P2 requests drive 2 and gets it.
Explanation:
A deadlock is a condition where two computer programs allocate the same resource essentially prevent access by each other and both programs stop working.
When every process or thread is awaiting for a resource to be released which is managed by another process a number of processes or themes are blocked.
Here is an example of a deadlock scenario. All connections are blocked; everybody hopes to see an incident that never takes place.
#1) Which is faster, a hi-speed usb port or a superspeed usb port?
Answer: superspeed usb port. USB 3.0 is the third major version of the Universal Serial Bus (USB) standard for interfacing computers and electronic devices. Among other improvements, USB 3.0 adds the new transfer rate referred to as SuperSpeed USB (SS) that can transfer data at up to 5 Gbit/s thats 625 MB/s.
