What is the difference between a hard drive and a tape drive? Hard drives use magnetic heads and are fast to write data; tape drives write to disks and are fast to retrieve data. Hard drives write to disks and are fast to retrieve data; tape drives use magnetic heads and are fast to write data. Hard drives use magnetic heads and are best for archival data; tape drives write to disks and are used for ongoing backups. Hard drives write to disks and are used for ongoing backups; tape drives use magnetic heads and are best for archival data.
Answer:
A tape drive provides sequential access storage, unlike a hard disk drive, which provides direct access storage. A disk drive can move to any position on the disk in a few milliseconds, but a tape drive must physically wind tape between reels to read any one particular piece of data.
Explanation:
Architecturally tape drives are sequential storage, meaning that if you need to access some data at the end of the tape you needed to seek to the end and retrieve it. This can take seconds or minutes. Disks, OTOH are random access. Some hard drives use rotating media and movable heads , so the seek times are instantaneous , at least compared with tape drives. However, like tapes, there is a big advantage to using a rotating hard drive as sequential storage. It takes time, measured in milliseconds, for a head to move to another track. So traditionally, random access is much slower than sequential access.
SSDs have no internal moving parts so random access occurs in the same time frame as sequential access. Moreover, these drives usually have very high performance. For example, they can saturate a SATA data link, meaning that the SATA connection to the motherboard is now a bottleneck in disk access.
At one time tape drives were very popular. They were a low-cost alternative to using disks as backup. They were especially useful when IBM invented the Winchester “fixed” drive. This meant that the hard drive is fixed within its enclosure like they are today. Prior to this one could remove the drive pack and replace it. This was helpful when upgrading to a new version of the operating system as it was simple to replace the older drive pack should there be a problem.
Tape drives can be used in larger data centers, due to the fact that tape volumes can be removed and replaced so that the actual tape drive can backup many disk sets. Also the tape volumes can be stored off-site or in a fire-proof vault so this is valuable in a data recovery scenario.

The answer is IP because, "The most significant protocol at layer 3 (also called the network layer) is the Internet Protocol, or IP. IP is the standard for routing packets across interconnected networks--hence, the name internet." - (ibm.com)
Your knowledge of algorithms helps you obtain an exciting job with the Acme Computer Company, along with a $10,000 signing bonus. You decide to invest this money with the goal of maximizing your return at the end of 10 years. You decide to use the Amalgamated Investment Company to manage your investments. Amalgamated Investments requires you to observe the following rules. It offers n different investments, numbered 1 through n. In each year j , investment i provides a return rate of rij . In other words, if you invest d dollars in investment i in year j , then at the end of year j, you have drij dollars. The return rates are guaranteed, that is, you are given all the return rates for the next 10 years for each investment. You make investment decisions only once per year. At the end of each year, you can leave the money made in the previous year in the same investments, or you can shift money to other investments, by either shifting money between existing investments or moving money to a new investement. If you do not move your money between two consecutive years, you pay a fee of f1 dollars, whereas if you switch your money, you pay a fee of f2 dollars, where f2 > f1.
a) The problem, as stated, allows you to invest your money in multiple investments in each year. Prove that there exists an optimal investment strategy that, in each year, puts all the money into a single investment. (Recall that an optimal investment strategy maximizes the amount of money after 10 years and is not concerned with any other objectives, such as minimizing risk.)
b) Prove that the problem of planning your optimal investment strategy exhibits optimal substructure.
c) Design an algorithm that plans your optimal investment strategy. What is the running time of your algorithm?
d) Suppose that Amalgamated Investments imposed the additional restriction that, at any point, you can have no more than $15,000 in any one investment. Show that the problem of maximizing your income at the end of 10 years no longer exhibits optimal substructure.
Answer:
C
Explanation:
Modify the statistics program from this chapter so that client programshave more flexibility in computing the mean and/ or standard deviation.Specifically, redesign the library to have the following functions:mean(nums) Returns the mean of numbers in nums.stdDev(nums) Returns the standard deviation of nums.meanStdDev (nums) Returns both the mean and standard deviation of nums.
Answer and Explanation:
Using Javascript:
function mean(nums){
var array_numbers= new array(nums);
var meanofNums= array_numbers.reduce()/array_numbers.length;
Console.log(meanofNums);
}
Function Std(nums){
var OurArray= new Array(nums);
var meanOfnums= mean(nums);
var i;
for(i=0; i<=OurArray.length; i++){
OurArray[i]= OurArray[i]-meanOfnums*OurArray[i]-meanOfnums;
}
var al_stdOfnums= OurArray.reduce()/OurArray.length;
var stdOfnums= Math. sqrt(al_stdOfnums);
Console.log(stdOfnums);
}
function meanStdDev (nums){
mean(nums);
Std(nums);
}
/*From the code above, we have defined functions and used them in the last function definition meanStdDev (nums), making for code reusability. In defining the functions, we have followed the formulas for calculating mean and standard deviations and implemented in that order. Notice how we used a for loop in std(nums) function definition to iterate through the elements of the array nums, squaring each value and reassigning a new value for each element(using index value) in the array. We then added these values in array using reduce method, dividing by array length and square rooting the value using the math object method sqrt().*/
Write a Raptor program that will generate a random number between 1 and 10; do not display the randomly generated number. Let the user guess within 3 tries what the random number is. Display hints to help the user, for example "Your guess was too high!". Display appropriate messages based on each try, for example, "1 remaining try" or "You guessed correctly!"
Answer:
Using javascript, explanation with javascript comment
Explanation:
function guessNumber(){
var randomize= math.random()*10;
var roundrand= math.floor(randomize);
var getInput= prompt("guess number from 1 to 10");
var x= 3;
do(
if(getInput>roundrand){
Console.log("your guess is too high");
guessNumber();
}
if(getInput<roundrand){
Console.log("your guess is too high");
guessNumber();
}
else{
Console.log("you are correct pal!");
break;
}
)
while(x<=3)
}
/*Observe that we have used a recursive function that calls the function guessNumber again inside the function definition if the input fails the if condition and doesn't guess correctly. It checks for a correct number 3 times with the do... while loop and breaks out of the function once the user enters a correct input.*/

De que se dio cuenta el sol al participar de la limpieza de playas?
La respuesta correcta para esta pregunta abierta es ls siguiente.
A pesar de que no se anexan opciones o incisos para responder, ni tampoco anexas algún contexto, lectura, libro artículo para poder responder, tratando de ayudarte hicimos una profunda investigación y podemos comentarte lo siguiente.
¿De que se dio cuenta el sol al participar de la limpieza de playas?
El Sol se dio cuenta de que desafortunadamente, los humanos no cuidan los océanos ya que tiran mucha basura y desperdicios al mar. Por lo tanto, lo contaminan.
Por esa razón, el Sol hizo una reflexión. La reflexión fu en el sentido del grado de daño que estamos provocando al mar y al medio ambiente en general. Lo estamos dañando.
Esto nos afecta a todos en mayor o menor grado porque el humano depende totalmente del medio ambiente y de la naturaleza. Aquí es donde la conciencia social debe hacer un alto para reflexionar y preguntarse hasta cuándo resistirá el medio ambiente tanta daño que se le ha provocado. La conciencia social debe crear un comportamiento social que actúo inmediatamente para proteger a la naturaleza, los mares, los ríos, los lagos, las selvas, los bosques, los desiertos, las tundras, los animales.
El ser humano depende de esos ecosistemas, y si los seguimos contaminando, estaremos acelerando nuestra destrucción. Debemos proteger el medio ambiente y crear una mayor conciencia en la importancia de la responsabilidad social.

"in a corporate environment, a well integrated management information system is a hacker's dream" . With reference to two examples, discuss the extent to which you agree or disagree to this statement
Answer:
Agree.
Explanation:
In a corporate environments systems are usually integrated to improve work efficiency. The more integration will result in well structured data organizing. It is necessary to put controls on misuse of this data. There should be strict internal controls placed in the system to avoid haccking as if there is hacck attack in one system, the whole integration may be haccked. The company should have backup plan in case of hacck attack so to completely shut down current system and work on another secured system to continue business operations.

On SnapI blocked someone, unblocked them and I want to add them again but I forgot their username. Is there anything I can do? Does snap have a list of like my former friends or people I’ve blocked?
Answer:
There is no list of people you had blocked formerly, however you should have seen their username when unblocking them? That's the only way I can think to find their user. Maybe if you have a friend who knows their username, you can get it that way. Or if you remember just a bit of it or their first/last name, you can try searching that.
ou use productivity apps on your iPad tablet device while traveling between client sites. You're concerned that you may lose your iPad while on the road and want to protect the data stored on it from being compromised. Currently, your iPad uses a 4-digit PIN number for a passcode. You want to use a more complex alpha-numeric passcode. You also want all data on the device to be erased if the wrong passcode is entered more than 10 consecutive times. What should you do
Answer:
Enable the Erase data optionDisable the simple passcode optionExplanation:
Most smartphone security experts agree that one way to prevent unauthorized access to one's iPad is to enable the erase data feature. Enabling this feature is believed to allow the possibility of all data on the device to be erased if a wrong passcode is entered after a specified number of times.
Of course, it is also possible to set a complex alphanumeric passcode, however, you'll need to first disable the simple passcode option.

Elsa wants to save her work at the office to be continued at home either on a pen drive or CD. Outline three reasons why she will choose the pen drive over the CD
Answer:
Pen Drive offers more accessibility
Not every device is equipped with a CD player but every device has a USB port for a pen Drive. Saving on the pen Drive will therefore enable the data to be more accessible.
Pen Drive has more space.
CDs usually have a storage capacity of below a gigabyte whilst pen drives can reach up to 2 terabytes thereby offering exponentially more space to save data.
Safety of Data
CDs are more prone to damage as data could be lost if the CD is scratches. Pen Drives on the other hand are encased in an outer case that protects the data.
