In a batch operating system, three jobs JOBI, JOB2, JOB3 are submitted for ex- ecution. Each job involves an I/O activity, a CPU time, and another 1/0 activity. JOB1 requires a total of 21 ms, with 3 ms CPC time. JOB2 requires 29 ms total time with 5 ms CPU time. JOB3 requires 14 ms total time with 4 is CPU time. 3.1 What will be the CPU utilisation for uniprogramming? Write down all interme diate steps. 3.2 What will be the CPU utilisation for multiprogramming? Write down all inter- mediate steps
Answer:
The answer to this question can be defined as follows:
In option 1, the answer is "18.75%".
In option 2, the answer is "33%".
Explanation:
Given:
JOB 1-Time of the CPU = 3ms, rest = 18ms, sum = 21
JOB 2-Time of the CPU = 5ms, rest = 24ms, sum = 29
JOB 3 -Time of the CPU =4ms, rest = 10ms, sum = 14
In option 1:
whenever the job has also been allocating the system, in the uni-programs system, which looks at the CPU until it is complete.
Formula:
[tex]\text{Utilization of CPU} =\frac{ \text{total time of CPU} }{ \text{full real time}}[/tex]
[tex]=\frac{(3+5+4)}{(21+29+14)}[/tex]
[tex]=\frac{12}{64}\\\\= 0.1875\\\\=18.75%[/tex]
In option 2:
However, if any software is interested in other operations like I / o, it can assign to the CPU Processor to others Systems and other software may be carrying out I / o operations there while the processor is with any other application.
Formula:
[tex]\text{Utilization of CPU} =\frac{ \text{total time of CPU} }{ \text{full real time}}[/tex]
[tex]=\frac{12}{36}\\\\=\frac{1}{3}\\\\=.33\\\\= 33 \%[/tex]

When Alice uses her private key to decrypt a message, the virus would wake up and make a note of it. The next time that Alice connects to the Internet, the virus would surreptitiously send the private key to Eve, thereby allowing her to decipher all subsequent messages sent to Alice. One way to better connect with this excerpt is to

Complete the body of the format_name function. This function receives the first_name and last_name parameters and then returns a properly formatted string. Specifically: If both the last_name and the first_name parameters are supplied, the function should return like so:
Answer:
Here is the Python program:
def format_name(first_name, last_name): #function definition of format_name that takes first_name and last_name as parameters
if first_name != '' and last_name != '': #checks if first_name and last_name both are not equal to " "
return ("Name: " + last_name + ", " + first_name) #returns first name and last_name in format: "Name: last_name, first_name"
elif first_name != '' or last_name != '': #checks if either of the first_name or last_name is not equal to " "
return ("Name: " + last_name + first_name) #returns first name and last_name in format: "Name: last_name" or "Name: first_name"
else: #if both names are blank
return '' #return ""
Explanation:
The working of the above function can be checked by using the following statements:
print(format_name("Ernest", "Hemingway"))
print(format_name("Voltaire", ""))
print(format_name("", "Madonna"))
print(format_name("", ""))
The program has a function format_name which takes two strings i.e. the first_name and last_name as parameters and returns the formatted string.
The first if condition checks if both the first_name and last_name are blank. For example if first_name = "Ernest" and last_name= "Hemingway" this means both the first_name and last_name are not blank or empty. So If this condition evaluates to true then the following statement is returned:
return ("Name: " + last_name + ", " + first_name)
This returns the last_name string first followed by a comma in between and then first_name string in the last. For the above example the string is printed in the following format:
Name: Hemingway, Ernest
The elif condition checks if either of the first_name or last_name is blank. For example if first_name = "Voltaire" and last_name= "" this means last_name is blank or empty. So if this condition evaluates to true then the following statement is returned:
return ("Name: " + last_name + first_name)
This returns the last_name string. For the above example the string is printed in the following format:
Name: Voltaire
IF none of the above condition is true and both the first_name and last_name are blank then the following statement is returned
return ''
This will just print and blank space in output.
The program and its output is attached.
¿por que la toria de lamarck sobre el alargamiento del cuello de las jirafas por el esfuerzo continuado no pasara a sus descendientes? Porfa es ciencia y ambiente estoy en el peru
Respuesta: Los caracteres adquiridos no se transmiten genéticamente porque no modifican el ADN de los organismos
Explicación:
Jean-Baptiste Lamarck al igual que Charles Darwin, propuso una teoría sobre la evolución que explicaba cambios en los organismos a través del tiempo. La teoría de Lamarck se enfocaba en condiciones en el ambiente que propiciaban cambios en los organismos. Un ejemplo de esto son las jirafas, que de acurdo a Lamarck tenían cuellos largos debido al esfuerzo continuado para comer hojas de árboles altos. Esto significa que la característica de cuello largo era adquirido por las jirafas durante su vida y según Lamarck se transmitiría a sus descendientes.
Sin embargo, se ha comprobado que los caracteres adquiridos no modifican el ADN de los organismos, por ejemplo las cirugías estéticas no cambian el ADN de una persona y por esta razón no son transmitidos a sus descendientes. Por el contrario, en las poblaciones de organismos ciertas características prevalencen en el tiempo debido a la selección natural. Esto significa que el cuello de las jirafas es el resultado que el cuello largo sea una característica beneficiosa que ha prevalecido debido a la selección natural y no de características adquiridas que son transmitidas a descendientes.

You have an application that for legal reasons must be hosted in the United States when U.S. citizens access it. The application must be hosted in the European Union when citizens of the EU access it. For all other citizens of the world, the application must be hosted in Sydney. Which routing policy should you choose in order to achieve this
Question options:
A. Latency-based routing
B. Simple routing
C. Geolocation routing
D. Failover routing
Answer:
C. Geolocation routing
Explanation:
Geolocation routing is used in allocating resources for different traffic sources originating from different geographical locations. Consequently you are allocating a different resource to handle a different DNS query based on the location/origination of the DNS query. In the above example, you will need to for example to route all queries from any other place in the world that is not US or Europe to a load balancer for Sydney. Your application in their different locations using geolocation routing would have to be adapted and localized to the region so as to serve the audience there

As the security administrator for your organization, you must be aware of all types of attacks that can occur and plan for them. Which type of attack uses more than one computer to attack the victim?
Answer:
The answer is "DDoS "
Explanation:
The distributed denial of service attack (DDoS) occurs whenever a directed program's wireless data or assets, generally one or even more application servers, were also swamped by various machines. This attack is always the consequence of many affected systems, that fill up the target network with traffic.
This attack is aimed to avoid legal customers of one's website from accessing it. In being effective in a DDoS attack, further demands need to be sent to the hacker than even the victim's server could deal with. One other way to successfully attack is to send fake requests from the attacker.As you're helping a user configure her e-mail over the phone, she remarks that the IP address is different than it was when she checked last week. This surprises her, since she didn't make any changes to her TCP/IP configuration. The user has had no problems running her web browser. You immediately know that:
Answer:
D. Her computer is a DHCP client.
Explanation:
Since in the question it is mentioned that IP address is different as compared in the previous week also the user did not make any changes with respect to the TCP/IP configuration and the system is working well
So this situation represents that the user computer is a client of DHCP as it deals with the client-server protocol in which it automatically generates the IP i.e Internet protocol along with the IP address

The new document states: (C) On 29 September, Operation Panda will commence. What concept is used to derivatively classify the statement in the new document?
Answer:
The answer is "Contained in"
Explanation:
Its term refers to the classified information of the extraction process, even though outlined in an authorized categorization instruction origin without extra explanation or review, and incorporates these data in a new document.
In this concept, the information appears in the extracted word-for-word, its definition of 'in' will apply, or if its data has been paraphrased or restated from the current text, that's why we can say that this concept derivatively classifies the statement in new documents.
