Answer:
a. 2100
b. 2199
Explanation:
GIven that:
The file size = 1000 MB
The payload size is = 100 bytes
The negotiated window size is = 1000 bytes.
This implies that the sliding window can accommodate maximum number of 10 packets
The sender receives an ACK 1200 from the receiver.
Total byte of the file is :
1000 MB = 1024000000 bytes
a.
Sender receives an ACK 1200 from the receiver but still two packets are still unacknowledged
=1200 + 9 * 100
= 1200 + 900
= 2100
b. What is the last byte number that can be sent without an ACK being sent by the receiver?
b. Usually byte number starts from zero, in the first packet, the last byte will be 99 because it is in 1000th place.
Thus; the last byte number send is :
= 1200 + 10 *100 -1
= 1200 + 1000-1
= 1200 + 999
= 2199
The answer is 2 frequencies.
A Full-Duplex QAM 64 K Modem uses two frequencies. One frequency is used for upstream and the other for downstream. A variety of common QAM forms are available and include, 16 QAM, 32 QAM, 64 QAM, and 256 QAM. For example, for domestic broadcast use, 64 and 256 QAM are used for cable modem and digital cable TV. The modulation scheme for this modem uses both amplitude and phase.
Answer:
Option C is the correct option to the following question
Explanation:
Because there are not any limits is required of sending data and packets between host A and host B by the routers and the router permit more than one paths between the hosts for the establishment of the connectivity st two distinct locations in the routing protocol. The router transmits the packets between the hosts that is produced by link-state protocol.
Answer:
Attempts to modify the value of a variable defined const are caught at execution time
Explanation:
The false statement among the options is Attempts to edit the value of a variable defined const are caught at execution time while other options are true.
A const variable should not be modify because the main reason of having a const variable is not to make modifying it possible. If you prefer a variable which you may likely want to modify at some point, then don't just add a const qualifier on it. Furthermore, Any code which modify's a const by force via (pointer) hackery invokes Undefined Behavior
