Answer:
a. 0.01
b. 0.001
c. The identification field of the packet fragment can be used to uniquely identify and collate the fragments lost in transmission.
Explanation:
The probability of losing a packet is 10% or 0.1, so the probability of losing the packet twice during transmission;
= 0.1 x 0.1 = 0.01
When any fragments have been part of the transmission, the probability of the packet is dependent on the fragments;
= 0.01 x 0.1 = 0.001
The identification field is a unique 16-bit value assigned to an IPv4 packet, when a packet is fragmented for transmission, its field is used to collate the unique fragments in the packet.
Answer:
Option (D) is the right answer.
Explanation:
DHCP term used as a short form of dynamic host configuration protocol, which is used to assigns the IP address automatically according to the network.
According to the scenario, the system is getting the wrong IP address that resulting in internet disconnection which is a failure of the DHCP server because it is responsible for assigning the right IP address to the system.
Hence option (D) is the most appropriate answer.
While other options are wrong because of the following reasons:
- Static IP is the type of IP address which is fix and doesn't change in the system after rebooting, hence it has no connection in the change of IP address.
- If the DHCP server is working well there is no chance of interference from the surrounding device.
- Network setting has no connection with computer power supply as SMPS is used to give power and boot system only.
A time bomb virus is a virus that is triggered on a certain date. It is a malicious program that is designed to release virus unto a system. Once the time has arrived, it will automatically start working what it is programmed to do since any virus could do anything depending on what it is designed to do.
Explanation:
Acid rain can cause serious problems for many different animals and plants. As a result, the entire food web is affected. For example, acid rain can cause phytoplankton in lakes to die. Insects, which rely on phytoplankton for food, now have less food to eat, and they begin to die as a result.
