Answer:

The answer to this question is option "d".

Explanation:

In this question option d (A user fills out a form to construct a description of the data desired in a SQL search) is not true. Because SQL stands for Structured Query Language. This is a query language used to communicate with a database and a user fills the form. Which is not possible in the SQL. So the option d is not true.

In basic network scanning, ICMP Echo Requests (type 8) are sent to host computers from the attacker, who waits for which type of
Hoochie [10]

Answer:

d. ICMP Echo Reply (type 0)

Explanation:

ICMP or internet control message protocol is an Internet layer protocol in the TCP/IP suite. It works together with routing devices like the router to send messages based on results sensed in the network.

The RFC 1122 has stated that the ICMP server and end user application be configured or installed in user devices, for receiving and sending ICMP echo request packets and reply. The process is called pinging.

For an attacker to implement ping of ping, he needs to confirm if the target user in live by sending an ICMP echo request packet type 8, to receive an ICMP echo reply type0.

You are trying to troubleshoot a desktop power supply issue using a voltmeter. Which of the following options are the MOST commo
vredina [299]

Answer:

The correct answers are: (A) +/- 5V and (B) +/- 12V

Explanation:

First at all, the purpose of the power supply is transforming from AC (Alternating Current) to DC (Direct Current) for use this energy in chips and electronics devices that consume this type of power. Usually the most common DC voltage for electronics is 5V but in your CPU you also have other devices that might going to need more voltage like fan or hard drives thats ´s why 12V is an also an option. Now some other devices are going to need negative sources such -5V or -12V as well.

Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, a
Margaret [11]

Explanation:

A.)

we have two machines M1 and M2

cpi stands for clocks per instruction.

to get cpi for machine 1:

= we multiply frequencies with their corresponding M1 cycles and add everything up

50/100 x 1 = 0.5

20/100 x 2 = 0.4

30/100 x 3 = 0.9

CPI for M1 = 0.5 + 0.4 + 0.9 = 1.8

We find CPI for machine 2

we use the same formula we used for 1 above

50/100 x 2 = 1

20/100 x 3 = 0.6

30/100 x 4 = 1.2

CPI for m2 =  1 + 0.6 + 1.2 = 2.8

B.)

CPU execution time for m1 and m2

this is calculated by using the formula;

I * CPI/clock cycle time

execution time for A:

= I * 1.8/60X10⁶

= I x 30 nsec

execution time b:

I x 2.8/80x10⁶

= I x 35 nsec

What is the destination ip address when an ipv4 host sends a dhcpdiscover message?
hjlf

The destination ip address when an ipv4 host sends a DHCPDISCOVER message Because a DHCP client does not have a valid IPv4 address, it must use a broadcast IP address of 255.255. 255.255 as the destination address to communicate with the DHCP server.

<h3>What does the DHCP server do when it receives the Dhcpdiscover message?</h3>

When the lease has expired, the client must start over with the DHCPDISCOVER process. The client ends the lease by sending a DHCPRELEASE message to the DHCP server. The server will then return the client's IP address to the available address pool.

<h3>What is a Dhcpdiscover message?</h3>

The DHCPDISCOVER message contains an identifier unique to the client (typically the MAC address). The message might also contain other requests, such as requested options (for example, subnet mask, domain name server, domain name, or static route). The message is sent out as a broadcast.
