Pinterest, a visual bookmarking Website, logs more than 14 terabytes of new data each day, which means its storage needs are constantly changing. As a result, Pinterest has turned to Amazon for _______.a. storage as a service
b. grid computing
c. cloud computing
d. infrastructure as a service
Answer:
The correct answer is option (A).
Explanation:
Pinterest has turned to amazon for storage as a service because it continuously needs a large amount of storage as given in the scenario.
While the other options are not correct because of the following reasons:
Grid computing can be defined as the concept of connection between a large number of computers in an architectural way who work to obtain the same goal but grid computing can not fulfill the need for storage for Pinterest. Cloud computing can work as data storage which can be accessed from the internet anywhere but this can not fulfill the storage requirements for Pinterest as they are very huge. Infrastructure as a service is not correct because the need of the company is for storage.Final answer:
Pinterest uses Amazon's cloud computing service, specifically Infrastructure as a Service (IaaS), to handle their varying storage needs and scale resources efficiently.
Explanation:
Pinterest has turned to Amazon for cloud computing, particularly the service model known as Infrastructure as a Service (IaaS). Companies like Pinterest, with fluctuating storage needs, benefit from IaaS by only paying for the storage and computing power they use, allowing them to scale resources up or down as needed. This is a cost-effective solution for businesses of all sizes because it eliminates the need for significant upfront investment in hardware and IT staff. Using cloud services like Amazon Web Services (AWS), companies can host files, applications, and more, enjoying benefits like increased system speeds and flexibility. This model is perfect for Pinterest, which requires the ability to handle a massive 14 terabytes of new data each day.

If the ________ is too ______, the fuse will blow, protecting the meter.
Answer:
If the amperage is too high, the fuse will blow, protecting the meter.
Explanation:
Fuses are wires to prevent the destruction of electrical equipment. This destruction is caused by power surges
Digital Multimeters or DMMs are better fused, to avoid damage. This damage can occur if the amperage is too high and there is no fuse in the multimedia.
The fuse will get damaged first, therefore, disrupt the flow of current to the electronics.

When replacing a system board in a laptop, which feature is a must?
Dual core CPU
Having the integrated peripherals in the same locations as the old system board
More RAM
Quad core CPU
Answer:
Having the integrated peripherals in the same locations as the old system board
Explanation:
System board is the printed circuit board that is used to connect the peripheral devices. It provides the slots and ports to connect the peripherals devices.
If there is a need to replace the system board of the laptop. You can change the system board. On new system board, all the peripherals that are installed on previous (old) system board should be placed on new system board. As the system requirements are same, only printed circuit board of the system is changed.
The new system board is replica of the previous board so, we can not change peripheral of the system boards.
Software design and implementation are interleaved activities. The level of detail in the design depends on the type of system being developed and whether you are using a plan-driven or agile approach. True or false?
Answer:
True is the correct answer for the above question.
Explanation:
The software design consists of several phases which are also called the life cycle. It is used to develop the software.But there are so many models, that consist of rules and guidelines to states how these phases can work. It states that in which steps of the designing phase, which part of the life cycle works.For example, in the waterfall model, all phases work on a single time and there is no option to follow this in reverse scenario and in the agile model only one module is developed and proved by the client.So the style of the phase can state the model, which is followed in the software development process.This above concept can also be started from the question. Hence True is the correct answer.The Pentium 4 Prescott processor, released in 2004, had a clock rate of 3.6 GHz and voltage of 1.25 V. Assume that, on average, it consumed 10 W of static power and 90 W of dynamic power. The Core i5 Ivy Bridge, released in 2012, had a clock rate of 3.4 GHz and voltage of 0.9 V. Assume that, on average, it consumed 30 W of static power and 40 W of dynamic power. 1. For each processor find the average capacitive loads. 2. Find the percentage of the total dissipated power comprised by static power and the ratio of static power to dynamic power for each technology. 3. If the total dissipated power is to be reduced by 10%, how much should the voltage be reduced to maintain the same leakage current? Note: power is defined as the product of voltage and current.
Answer:
1. Capacitive load for pentium 4 prescott processor = 32 nF. Capacitive load for core i5 ivy processor = 29.05 nF
2. Percentage of total dissipated power comprised by static power for Pentium 4 Prescott processor = 10 %. The ratio of static power to dynamic power = 0.11
Percentage of total dissipated power comprised by static power for Core i5 Ivy Bridge processor = 42.86 %. The ratio of static power to dynamic power = 0.75
3. Reduction in voltage for Pentium 4 Prescott processor = 5.9 % reduction
Reduction in voltage for Core i5 Ivy Bridge processor = 9.8 % reduction
Explanation:
1. We know that dynamic power, P ≈ 1/2 CV²f where C is the capacitive load of the transistor, v its voltage and f the frequency.
So C ≈ 2P/V²f
For the Pentium 4 Prescott processor, V₁ = 1.25 V, f₁ = 3.6 GHz and P₁ = 90 W. Let C₁ be its capacitive load. So, C₁ ≈ 2P/V²f = 2 × 90 W/ (1.25 V)² × 3.6 × 10⁹ Hz = 3.2 × 10⁻⁸ F = 32 × 10⁻⁹ F = 32 nF
For the Core i% Ivy Bridge processor, V = 0.9 V, f = 3.4 GHz and P = 40 W. Let C₂ be its capacitive load. So, C₂ ≈ 2P/V²f = 2 × 40 W/ (0.9 V)² × 3.4 × 10⁹ Hz = 2.905 × 10⁻⁸ F = 29.05 × 10⁻⁹ F = 29.05 nF
2. Total power = static power + dynamic power.
For the Pentium 4 Prescott processor, static power = 10 W and dynamic power = 90 W. So, total power, P = 10 W + 90 W = 100 W.
The percentage of this total power that is static power = static power/total power × 100 = 10/100 × 100 = 10 %
The ratio of static power to dynamic power = static power/ dynamic power = 10/90 = 0.11
For the Core i5 Ivy Bridge processor, static power = 30 W and dynamic power = 40 W. So, total power, P = 30 W + 40 W = 70 W.
The percentage of this total power that is static power = static power/total power × 100 = 30/70 × 100 = 42.86 %
The ratio of static power to dynamic power = static power/ dynamic power = 30/40 = 0.75
3. We know Total power = static power + dynamic power. And that leakage current is due to static power. Since P = IV , I (leakage current) = P/ V
Since the total dissipated power is reduced by 10%, P₂ = (1 - 0.1)P₁ = 0.9P₁ where P₁ is the total power dissipated before the 10% reduction and P₂ is the new power dissipated after the 10% reduction in total dissipated power.
Let new total dissipated power, P₂ = new static power I₂V₂ + new dynamic power 1/2C₂V₂²f₂ = 0.9P₁.
For the Pentium 4 Prescott processor, P₂ = I₂V₂ + 1/2C₂V₂²f₂ = 0.9P₁. Since I₂(leakage current) = static power/voltage = 10 W/1.25 V = 8 A (since the leakage current is constant), we have
8 A × V₂ + 1/2 × 32 × 10⁻⁹ F × V₂² × 3.6 × 10⁹ Hz = 0.9 × 100
8V₂ + 57.6V₂² = 90. This leads to the quadratic equation
57.6V₂² + 8V₂ - 90 = 0. By the quadratic formula,
V₂ = [tex]\frac{-8 +/- \sqrt{8^{2} -4X57.6 X -90} }{2X57.6} = \frac{-8 +/- \sqrt{64 + 20736} }{115.2} = \frac{-8 +/- \sqrt{20800} }{115.2}\\=\frac{-8 +/- 144.222}{115.2}\\[/tex]
V₂ = 1.18 V or - 1.32 V .
Choosing the positive answer, the new voltage is 1.18 V. The percentage reduction is (new voltage - old voltage)/new voltage × 100 % = (1.18 - 1.25)/1.18 × 100 % = -0.07/1.18 × 100 % = -5.9 % . Which is a 5.9 % reduction from 1.25 V
For the Core i5 Ivy Bridge processor, P₂ = I₂V₂ + 1/2C₂V₂²f₂ = 0.9P₁. Since I₂(leakage current) = static power/voltage = 30 W/0.9 V = 33.33 A (since the leakage current is constant), we have
33.33 A × V₂ + 1/2 × 29.05 × 10⁻⁹ F × V₂² × 3.4 × 10⁹ Hz = 0.9 × 70
33.33V₂ + 49.385V₂² = 63. This leads to the quadratic equation
49.385V₂² + 33.33V₂ - 63 = 0. By the quadratic formula,
V₂ = [tex]\frac{-49.385 +/- \sqrt{49.385^{2} -4X33.33 X -63} }{2X33.33} = \frac{-49.385 +/- \sqrt{2438.8782 + 8399.916} }{66.66} = \frac{-49.385 +/- \sqrt{10838.794} }{66.66}\\=\frac{-49.385 +/- 104.110}{66.66}\\[/tex]
V₂ = 0.82 V or - 2.30 V .
Choosing the positive answer, the new voltage is 0.82 V. The percentage reduction is (new voltage - old voltage)/new voltage × 100 % = (0.82 - 0.9)/0.82 × 100 % = -0.08/0.82 × 100 % = -9.8 % . Which is a 9.8 % reduction from 0.9 V
After that So C ≈ 2P/V²f
After that For the Pentium 4 Prescott processor, V₁ = 1.25 V, f₁ = 3.6 GHz and P₁ = 90 W. then take C₁ be its capacitive load. So, C₁ ≈ 2P/V²f = 2 × 90 W/ (1.25 V)² × 3.6 × 10⁹ Hz = 3.2 × 10⁻⁸ F = 32 × 10⁻⁹ F = 32 nFSo that is For the Core i% Ivy Bridge processor, V = 0.9 V, f = 3.4 GHz and also P = 40 W. Let C₂ the capacitive load. So, C₂ ≈ 2P/V²f = 2 × 40 W/ (0.9 V)² × 3.4 × 10⁹ Hz = 2.905 × 10⁻⁸ F = 29.05 × 10⁻⁹ F = 29.05 nF
The next step will be Total power that is = static power + dynamic power.
When the Pentium 4 Prescott processor, static power that is = 10 W and dynamic power will be = 90 W. So, total power, P = 10 W + 90 W = 100 W. According to this total power that is static power will be= static power/total power × 100 = 10/100 × 100 = 10 % The ratio of static power to dynamic power will be = static power/ dynamic power = 10/90 = 0.11 For the next that Core i5 Ivy Bridge processor, static power = 30 W and dynamic power = 40 W. So, total power, P = 30 W + 40 W = 70 W. When The % of this total power that is static power = static power/total power × 100 = 30/70 × 100 = 42.86 % The ratio of static power to dynamic power will be = static power/ dynamic power = 30/40 = 0.75 When We know that Total power will be = static power + dynamic power. Since that P = IV , I (leakage current) = P/ V After that the total dissipated power is reduced by 10%, P₂ = (1 - 0.1)P₁ = 0.9P₁ where as P₁ is the total power dissipated before that the 10% reduction and that P₂ is the new power dissipated after the 10% reduction in total dissipated power. Let be new the total dissipated power, P₂ = new static power I₂V₂ + new dynamic power 1/2C₂V₂²f₂ = 0.9P₁. For the Pentium 4 Prescott processor, P₂ = I₂V₂ + 1/2C₂V₂²f₂ = 0.9P₁. After that I₂(leakage current) = static power/voltage is = 10 W/1.25 V = 8 A (since the leakage current is constant), now have8 A × V₂ + 1/2 × 32 × 10⁻⁹ F × V₂² × 3.6 × 10⁹ Hz = 0.9 × 100
8V₂ + 57.6V₂² = 90. This leads to the quadratic equation
57.6V₂² + 8V₂ - 90 = 0. By the quadratic formula, V₂ =
V₂ = 1.18 V that is - 1.32 V .
When the new voltage is 1.18 V. The percentage will be reduction is (new voltage - old voltage)/new voltage × 100 % = (1.18 - 1.25)/1.18 × 100 % = -0.07/1.18 × 100 % = -5.9 % . Which is a 5.9 % reduction from 1.25 V For the Core i5 Ivy Bridge processor, P₂ = I₂V₂ + 1/2C₂V₂²f₂ = 0.9P₁ I₂(leakage current) = static power/voltage = 30 W/0.9 V = 33.33 A (since the leakage current is constant), we have33.33 A × V₂ + 1/2 × 29.05 × 10⁻⁹ F × V₂² × 3.4 × 10⁹ Hz = 0.9 × 70
33.33V₂ + 49.385V₂² = 63. This leads to the quadratic equation
49.385V₂² + 33.33V₂ - 63 = 0. By the quadratic formula, V₂ =
V₂ = 0.82 V that is - 2.30 V .
The new voltage is 0.82 V. The % reduction is (new voltage - old voltage)/new voltage × 100 % = (0.82 - 0.9)/0.82 × 100 % = -0.08/0.82 × 100 % = -9.8 % . Which is a 9.8 % reduction from 0.9 VLearn more about:

Answer:
cyber attack
Explanation:
You are troubleshooting a network issue on a client computer and discover that the network card has an IP address of 169.254.196.200. What does this mean?
Answer:
Automatic Private IP Addressing (APIPA)
Explanation:
This usually means no static IP address is assigned to the computer. Therefore it cannot connect to the Dynamic Host Configuration Protocol (DHCP). It thus uses Automatic Private IP Addressing (APIPA)(which usually ranges from 169.254.0.1 to 169.254.255.254) to configure itself.
To resolve this, disconnect the computer from the network, assign or change the Static IP and reconnect. Alternately you can reset the Modem/Router.
An IP address of 169.254.196.200 indicates that the computer's network card has been assigned an Automatic Private IP Address (APIPA), which is used when it cannot reach a DHCP server.
When a computer is assigned an IP address of 169.254.196.200, it means that the network card has been assigned an Automatic Private IP Address (APIPA). APIPA is used by Microsoft Windows operating systems when the network card is set to obtain an IP address automatically, but the Dynamic Host Configuration Protocol (DHCP) server is not available or cannot be reached. In this situation, the operating system assigns an IP address in the 169.254.x.x range, enabling the computer to communicate with other devices on the same local network subnet, despite not being able to access the broader internet or external networks.
This situation is often a sign that there is a problem with the network's DHCP configuration or with the network itself. To resolve the issue, you would typically check the network connection, verify the DHCP server status, or review the network card settings on the impacted computer. The purpose of APIPA is to allow local network communication to continue until the DHCP issue can be resolved.

When it comes to data storage, if a user wants striping and backup, which RAID will do both?
RAID 0
RAID 1
RAID 5
RAID 10
RAID 10 is the correct RAID level that provides both striping for performance and mirroring for data backup, meeting the user's requirements.
When it comes to data storage, if a user desires both striping for performance and backup for redundancy, the appropriate RAID level to choose would be RAID 10 (also known as RAID 1+0). Here's a brief explanation of why the other RAID levels do not meet both criteria:RAID 0: Offers striping but no redundancy for backup.RAID 1: Offers redundancy for backup but no striping.RAID 5: Offers striping and parity for redundancy, but the redundancy is not a full backup; it's designed to survive a single drive failure.RAID 10: Combines the benefits of RAID 0 and RAID 1, providing both striping and mirroring for backup.Therefore, RAID 10 is the optimal choice for users seeking both performance enhancements via striping and data protection through backup.Devon would like to install a new hard drive on his computer.

A switch's port Gi0/1 has been correctly enabled with port security. The configuration sets the violation mode to restrict. A frame that violates the port security policy enters the interface, followed by a frame that does not. Which of the following answers correctly describe what happens in this scenario?(Choose two answers.)
a. The switch puts the interface into an err-disabled state when the first frame arrives.
b. The switch generates syslog messages about the violating traffic for the first frame.
c. The switch increments the violation counter for Gi0/1 by 1.
d. The switch discards both the first and second frame.
Answer:
B and C
Explanation:
When a frame that violates the port security policy enters the interface, followed by a frame that does not the following would possibly happen: The switch increments the violation counter for Gi0/1 by 1 or and the switch generates syslog messages about the violating traffic for the first frame.
Final answer:
With the violation mode set to restrict on a switch port, a syslog message is generated, and the violation counter is incremented by 1 when a frame violates the port security policy. The port does not go into an err-disabled state and non-violating traffic passes through normally.
Explanation:
When a switch port configured with port security receives a frame that violates the configured security policy, the behavior of the port depends on the violation mode set. In the case where the violation mode is set to restrict, the following occurs:
The switch will generate a syslog message about the violating traffic for the first frame, providing administrators with insight into the security event.The switch will increment the violation counter for the interface Gi0/1 by 1, which serves as a tally of the total number of violations.Unlike the shutdown violation mode, restrict does not disable the interface; therefore, the interface remains up and allows subsequent frames that do not violate the security policy to pass through.Given the available options, the correct answers to what happens when a frame violating the port security policy enters the interface are:
The switch generates syslog messages about the violating traffic for the first frame (b).The switch increments the violation counter for Gi0/1 by 1 (c).The second frame that does not violate the policy will be forwarded normally, as the port does not become err-disabled and the frame does not contribute to a policy violation.

Dustin runs a command at the command line trying to find out what kernel version the system is running. However, it doesn't give him the information he needs. He knows there is an option that can be used to display the kernel version. How can he find out which option to use?
Answer:
With the use of -h or -help switches.
Explanation:
Linux shell is a terminal in the Linux operating system that receives input or typed commands to perform an action based on the command. These commands are the same commands embedded in the icons of the graphic interface operating systems.
To get the kernel version of the Linux operating system in the command line prompt, the uname command among other useful commands can be used. To get help on how to use the command to get more information and more options, use the -h or -help switch next to the uname command.
Final answer:
Dustin can use the 'uname –a' command to display all system info or 'uname –r' to see just the kernel version. He should also consider system architecture when choosing binaries and use 'echo $0' to find out the current shell. Extensive online documentation and help systems provide further guidance.
Explanation:
To determine which kernel version the system is running, Dustin can use the uname command with the –a option in the command line. This option will provide all the information about the system, including the kernel version. If Dustin is specifically focused on the kernel, the uname –r command will give him the kernel version without the extra details.
Additionally, understanding the system architecture (32-bit vs 64-bit) is crucial when choosing the correct binaries to download and use, such as i86linux64 for a 64-bit GNU/Linux system. This knowledge combined with tools like wget allows users to download and install the correct software for their system. Should Dustin need more help, he can explore the detailed documentation available online or use the help system built into the command line.
Moreover, if he's operating on a non-Linux system like MacOS, he may need to search for compatible GNU core utils or consider using virtual machine software such as VirtualBox for a Linux distribution. It's also important to know which shell is in use, and Dustin can find this out by running echo $0 in the command line.
What are two compatibility issues that may arise between computer systems while transferring presentations?
(Fill in the blank).
Different video files and _____ can cause compatibility issues to arise between computer systems
Answer:
The ability to work together without changing is compatibility.
First is, various software versions included or installed on the computers. The second is the various operating systems in the computers.
Different video files and operating system versions_ can cause compatibility issues to arise between computer systems.
It might trigger compatibility problems with a few of the existing software once you update or even upgrade your operating system. This issue is very rare with upgrades, but very popular with full version upgrades such as Windows 7 to Windows 10.
Answer:
Video card adapted.
Explanation:
In computer systems, compatibility is the ability for a file to run in the computer system safely and smoothly without errors. Videos have several formats like MP3 and many more, that can run on several digital platforms.
A computer system video card adapter is an essential device that provides the memory and interface to run graphic files like the videos. For a video or presentation to be transferred between computer, it format needs to be compatible with the video cards and screen resolution of the device.
Determine the "M" value and number of data bits that can be represented by a single symbol using ASK where the possible amplitude values per symbol can be {0v, +1v, +2v, +3v, +4v, +5v, +6v, +7v}. a. M=2, N=1 bit per symbol b. M=4, N=2 bit per symbol c. M=6, N=3 bit per symbol d. M=8, N=3 bit per symbol
Answer:
d. M=8, N=3
Explanation:
The number of messages (M) that can be sent is 8. The eight messages are the listed amplitude values.
The number of bits per symbol (N) is log2(M) = log2(2^3) = 3.
M=8 messages can be sent, so N=3 bits per symbol.
