Answer:

In a stream cipher, the information is ciphered byte-by-byte.

In a block cipher, the information is ciphered block by block.

Explanation:

Suppose I have the following text:

Buffalo Bills New England Patriots

New York Jets Miami Dolphins

Each line is one byte, so, on the stream cipher, i am going to apply the ciphering algorithm on:

The letter B

The letter u

The letter f

Until

The letter s(of Miami Dolphins)

Now for the block cipher, i am saying that each line is a block, so the algorithm is going to be applied.

First on: Buffalo Bills New England Patriots

Then: New York Jets Miami Dolphins

// This pseudocode is intended to describe

ddd [48]

Applying given information of a computational language in pseudocode, a code may be written to represent computing the price of an item on sale for 10% off.

<h3>What is a pseudocode?</h3>

A pseudocode can be considered as a depiction of the steps represented in an algorithm, usually in plain (natural) language.

//This pseudocode is intended to describe

//computing the price of an item on sale for 10% off

START

input origPrice

discount = origPrice * 0.10

finalPrice = origPrice - discount

output finalPrice

STOP

//This pseudocode is intended to compute the number

//of miles per gallon you get with your car.

START

input milesTraveled

input gallonsOfGasUsed

milesPerGallon = milesTraveled / gallonsOfGasUsed

//milesPerGallon is computed using division

output milesPerGallon

//miles is misspelled, and the P in milesPerGallon should be uppercase

STOP

//Program should end with stop

//This pseudocode is intended to describe

//computing the per day cost of your rent

//in a 30-day month

START

input rent

costPerDay = rent / 30

// Comment indicates 31-day month

output costPerDay

// output should be costPerDay

STOP

What specific record type is found in every zone and contains information that identifies the server primarily responsible for t

ValentinkaMS [17]

The SOA is the specific record type found in every zone and contains information that identifies the sever primarily responsible for the zone as well as some operational properties for the zone.

Explanation:

The Start of Authority Records (SOA) has the following information they are

Serial Number: This number is used to find when zonal information should be replicated.

Responsible person: The Email address of a person is responsible for managing the zone.

Refresh Interval: It specifies how often a secondary DNS server tries to renew its zone information.

Retry Interval: It specifies the amount of time a secondary server waits before retrying the zone information has failed.

Expires After: IT specifies the amount of time before a secondary server considers its zone data if it can't contact with the primary server.

Minimum TTL: It specifies the default TTL value for a zone data when a TTL is not supplied.
