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:

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.

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.Devon would like to install a new hard drive on his computer. Because he does not have a SATA port available on his motherboard, he has decided to purchase a NVME SSD hard drive. How can Devon attach a NVME device to his computer?
Answer:
PCIe expansion card
U.2 port on the motherboard
M.2 slot on the motherboard
Explanation:
NVMe is a communications standard developed specially for SSDs by a consortium of vendors which operates across the PCIe bus (hence the ‘Express’ in the name), which allows the drives to act more like the fast memory that they are, rather than the hard disks they imitate.
If a user urchase a NVMe SSD hard drive and he doesn't have SATA port available on his motherboard, the user can attach the NVMe hard drive to his computer through the following:
PCIe expansion card U.2 port on the motherboard M.2 slot on the motherboardA 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.

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 you write a program that will run in a GUI environment as opposed to a
command-line environment, ____________.
you do not need to plan the logic
the logic is very different
users are more confused
some syntax is different
When you write a program that will run in a GUI environment as opposed to a
command-line environment, some syntax is different.
Explanation:
GUI (Graphical User Interface) which is the computer user interface uses graphical images to activate and run the applications.Command line interface is a interface that is in a text format, which can accept commands for a task.So, to program both interface, we need high level program skills with good understanding in programming languages like C++, C etc and algorithms. Here, the GUI syntax differs from the command line interface.Jessica wants to purchase a new hard drive. She wants a drive that has fast access because she will use it to edit videos on her PC. She also needs a lot of storage and wants to have at least 4 TB available to save her videos. Jessica wants to keep the cost down as much as possible. What type of hard drive should Jessica purchase?
Answer:
7200 RPM magnetic HDD with 4tb disk size.
Explanation:
The computer system storage is a hardware component used to store data permanently. It holds the operating system software files used to boot the system. The processor retrieves data from the hard disk drive to processing and stores the output back to the drive.
The RPM or resolution per minute is the speed of the disk on the drive per minute, the faster the disk, the faster the drive saves and transfer data.
The 4tb 7200 RPM magnetic HDD has a speed of 7200 resolution per minute, making it fast for saving and trimming and provides large storage space.
Final answer:
Jessica should purchase an SSD for fast and reliable storage while editing videos on her PC, ensuring both speed and reliability.
Explanation:
Jessica should purchase an SSD (Solid State Drive) for fast access and overall reliability when editing videos on her PC. SSDs are known for their speed and reduced risk of physical damage to moving parts.
Additionally, Jessica should look for an external SSD with USB 3.0 connection for compatibility with her project computers. This type of drive is often bus-powered, eliminating the need for a separate AC supply.
SSDs provide the speed, ample storage capacity, and reliability Jessica needs for video editing while keeping costs down.
