In a packet voice communications system, a source transmits packets containing digitizedspeech to a receiver. Because transmissi

on errors occasionally occur, an acknowledgment (ACK)or a nonacknowledgment (NAK) is transmitted back to the source to indicate the status of eachreceived packet. When the transmitter gets a NAK, the packet is retransmitted.Voice packets are delay sensitive and a packet can be transmitted a maximum ofdtimes. If apacket transmission is an independent Bernoulli trial with success probabilityp, what is the PMFofT, the number of times a packet is transmitted

If i don't update my computer what threat does my computer face?
Nadusha1986 [10]
Hey there! Hello!

Computer updates, especially smaller security updates, contain security information for new bugs, malware, viruses, etc. that have been written since your last update. So many of these are written for computers at any given time, meaning that keeping your computer updated is a significant step in keeping your computer's defense systems working. Paired up with legit anti-malware, virus protection software, good computer knowledge, and common sense, your computer can remain very safe from these viruses. 

Otherwise, there might be some bug or irregularity within your computer's system itself that was accidentally released an update or two ago by the creators of your computer's software, which may also pose a threat for your computer system. Updating your computer can most likely fix problems like these. But, more commonly, they just keep your computer up to date on the vicious computer threats that are now available for it since the previous update. 

Hope this helped you out! Feel free to ask me any additional questions if you have any. :-)

Can someone tell me how this is a SyntaxError! (Python3)
Basile [38]

Answer:

The expression on line 9 required 2 brackets

Explanation:

Given

The attached code

Required

Why syntax error.

The error points to line 10, but the error is actually from line 9

To get an integer input, the syntax is:

variable-name = int(input("Prompt"))

From the attached code, the line 9 is:

amount = int(input("Enter cheese order weight: ")

By comparing the syntax to the actual code on line 9, only 1 of the brackets is closed.

<em>This, in Python 3 is a sytax error</em>
