The ampere (/aempr/, US: /mpr/; symbol: A), also known as the amp, is the unit of electric current in the International System of Units (SI). One ampere is equal to one coulomb, or 6.2415090741018 electrons passing through a point in one second.
What is ampere?The ampere, commonly abbreviated as "amp," is the base unit of electric flow in the International System of Units (SI). It was named after French mathematician and physicist André-Marie Ampère (1775-1836), widely regarded as the father of electrodynamics. The ampere is defined by the International System of Units in terms of other base units by estimating the electromagnetic power between electrical conductors that carry the electric flow. The previous CGS estimation framework employed two distinct definitions of current, one based on SI units and the other on electric charge as the base unit. The charge unit is calculated by measuring the power between two charged metal plates. The ampere was then defined as one coulomb of charge per second. SI defines the coulomb as the unit of charge.

Suppose we have four jobs in a computer system, in the order JOB1, JOB2, JOB3 and JOB4. JOB1 requires 8 s of CPU time and 8 s of I/O time; JOB2 requires 4 s of CPU time and 14 s of disk time; JOB3 requires 6 s of CPU time; and, JOB4 requires 4 s of CPU time and 16 s of printer time. Define the following quantities for system utilization: • Turnaround time = actual time to complete a job • Throughput = average number of jobs completed per time period T • Processor utilization = percentage of time that the processor is active (not waiting) Compute these quantities (with illustrations if needed) in each of the following systems: a. A uniprogramming system, whereby each job executes to completion before the next job can start its execution. b. A multiprogramming system that follows a simple round-robin scheduling. Each process gets 2 s of CPU time turn-wise in a circular manner.
Answer:
Explanation:
a. Uniprogramming System:
Turnaround Time: For JOB1, the turnaround time is 16 s (8 s CPU time + 8 s I/O time). For JOB2, the turnaround time is 18 s (4 s CPU time + 14 s disk time). For JOB3, the turnaround time is 6 s (6 s CPU time). For JOB4, the turnaround time is 20 s (4 s CPU time + 16 s printer time).
Throughput: In a uniprogramming system, the throughput is equal to 1 job per time period, as only one job can be processed at a time.
Processor Utilization: For JOB1, the processor utilization is 8/16 = 50%. For JOB2, the processor utilization is 4/18 = 22.2%. For JOB3, the processor utilization is 6/6 = 100%. For JOB4, the processor utilization is 4/20 = 20%.
b. Multiprogramming System:
Turnaround Time: For JOB1, the turnaround time is 24 s (8 s CPU time + 8 s I/O time + 8 s waiting). For JOB2, the turnaround time is 24 s (4 s CPU time + 14 s disk time + 6 s waiting). For JOB3, the turnaround time is 16 s (6 s CPU time + 10 s waiting). For JOB4, the turnaround time is 32 s (4 s CPU time + 16 s printer time + 12 s waiting).
Throughput: In a multiprogramming system, the throughput is equal to 4 jobs per time period, as all four jobs can be processed concurrently.
Processor Utilization: For JOB1, the processor utilization is 8/24 = 33.3%. For JOB2, the processor utilization is 4/24 = 16.7%. For JOB3, the processor utilization is 6/16 = 37.5%. For JOB4, the processor utilization is 4/32 = 12.5%.
Here are the turnaround time, throughput, and processor utilization for the four jobs in a uniprogramming and round-robin system:
UniprogrammingTurnaround time:
JOB1: 16 s
JOB2: 22 s
JOB3: 12 s
JOB4: 20 s
Throughput: 1 job/16 s
Processor utilization: 50%
Round-Robin
Turnaround time:
JOB1: 18 s
JOB2: 14 s
JOB3: 10 s
JOB4: 18 s
Throughput: 2 jobs/16 s
Processor utilization: 62.5%
The difference in turnaround time between the two systems is due to the fact that in a uniprogramming system, the CPU is idle while a job is waiting for I/O. In a round-robin system, the CPU is always running, even if it is only running a short burst of code for another job.
The difference in throughput between the two systems is also due to the fact that in a round-robin system, the CPU is always running, so more jobs can be completed in a given amount of time.
The processor utilization is higher in a round-robin system because the CPU is not idle as often. However, the turnaround time is also higher because the jobs have to share the CPU.

1 Two balls are drawn in succession without replacement from a box containing 4 red balls and 3 black balls. Let Y be the random variable, where Y is the number of the red balls. What is the expected value of this random event?
2. Two balls are drawn in succession from a box without repetition containing 3 red 3 blue and four yellow marbles. What is the probability that they are of the same color?
Answer:
See below, please.
Explanation:
Part 1.
Let Y be the random variable representing the number of red balls drawn in succession. The possible outcomes are (R, R), (R, B), (B, R), and (B, B). We can calculate the probability of each outcome as follows
P(Y=0) = P(B, B) = (3/7) * (2/6) = 1/7
P(Y=1) = P(R, B) + P(B, R) = (4/7) * (3/6) + (3/7) * (4/6) = 12/42 + 12/42 = 24/42
P(Y=2) = P(R, R) = (4/7) * (3/6) = 2/7
The expected value of Y is given by:
E(Y) = Σ yi * P(Y=y)
= 0 * (1/7) + 1 * (24/42) + 2 * (2/7)
= 0 + 8/14 + 4/7
= 16/14
= 1.14
Therefore, the expected value of Y is 1.14.
Part 2.
The total number of ways to draw two marbles from the box is 10C2 = 45. The number of ways to draw two marbles of the same color is 3C2 + 4C2 = 3 + 6 = 9. Therefore, the probability of drawing two marbles of the same color is
P(same color) = 9/45 = 1/5
Therefore, the probability that the two balls are of the same color is 1/5.

Networks
Use a pencil and paper or a computer-based drawing program, and diagram the LAN (local area network) described below. You will read and analyze the description below and then draw your LAN based on the description. Upon completion of your drawing, you will discuss how to change the LAN into a WAN.
Scenario: A small photocopying business
Elements your LAN must include:
Four computers: These computers connect to a network server and are for the public to use to upload their files.
Photocopy machine: This server is connected to the business's high-capacity networked photocopy machine, which works like a regular industrial/business copy machine, but also takes "orders" from the network server.
One employee business computer: This computer is connected to the network server for files that need to be sent digitally to the high-capacity photocopy machine.
One employee internal computer: This computer is for interoffice communication and business functions such as accounting. This computer is connected to an applications server that houses the business's application software, including its word processor, accounting software, and so on.
One server for Internet orders: This server copies orders that come in from other businesses via the Internet. Customers submit their orders via an Internet application that submits the file and sends the requests directly to the business to be retrieved by the copy machine operator (orders go directly from that server to the copy machine, which has its own monitor and displays jobs from customers in the shop and jobs from the Internet that are waiting to be processed).
Your diagram must show the computers, the connection from the computers to the network, and the network servers. You may use a simple rectangle shape to represent each computer and the other components, but please label the shapes. Use straight lines to represent the wires (connections) and network servers.
At the bottom of the drawing, include a two- to four-sentence description of what could be changed to make this LAN a WAN.
Answer:
To convert the LAN into a WAN, the following changes could be made:
A WAN connection would need to be established between the LAN and other remote locations using technologies such as leased lines, satellite links, or the internet.
The LAN's central server would become the WAN's central hub, allowing communication and data sharing between different locations of the business.
Additional networking devices such as routers, switches, and hubs may be required to connect the LAN to the WAN and provide connectivity between different locations.
The WAN may require additional security measures, such as firewalls and virtual private networks (VPNs), to ensure that data remains secure during transmission over the wide area network.
The WAN may also require additional bandwidth and higher-capacity network components to support the increased data traffic and larger number of users across multiple locations.

Answer:
see attached
Explanation:
You want to construct a triangle with a perimeter of 55 mm and angles in the ratio 2:1:3.
AnglesThe 2+1+3 = 6 ratio units represent 180°, the sum of angles in a triangle. Hence each unit in the ratio is 180°/6 = 30°.
The angles are 60° : 30° : 90°.
PerimeterFrom your knowledge of "special triangles," you know the side lengths in a 30°-60°-90° triangle have the ratios 1 : √3 : 2.
That is, the perimeter of the triangle is (1+√3 +2) = 3+√3 times the length of the shortest side.
Side lengthsThe shortest side of the triangle will have the length ...
[tex]\dfrac{55\text{ mm}}{3+\sqrt{3}}=\dfrac{(3-\sqrt{3})(55\text{ mm})}{(3-\sqrt{3})(3+\sqrt{3})}= \dfrac{(165-55\sqrt{3})\text{ mm}}{3^2-(\sqrt{3})^2}\\\\\\=(27.5-\dfrac{55}{6}\sqrt{3})\text{ mm}\approx 11.6229\text{ mm}[/tex]
The longest side will be double this length, about 23.2457 mm. The side of intermediate length will be (55√3 -55)/2 ≈ 20.1314 mm.
ConstructionIf you're doing the drawing using only a compass and straightedge, you will start by constructing perpendicular lines (the right angle). Mark off 1 and two lengths of the shortest side on one of these perpendicular segments. Then draw the hypotenuse as 2 times the short length from the end of the short length. It will intersect the perpendicular segment at √3 times the short length.
The tricky part here is constructing a line segment of the desired irrational length. One way to do this is to construct a 30-60-90 triangle with a unit-length short side, then "unfold" it to a line segment with parts that are 1, √3, and 2 units long. A "proportioning" construction can divide the 55 mm length of the perimeter into these proportions, (10 mm might be a good "unit length" for this.)
__
Additional comment
The desired dimensions are sufficiently small that an accurate compass/straightedge construction will be difficult. It is unlikely your pencil line width is much less than about 0.2 mm, so already the error is about 2% in any length.
The attached drawing was made by telling the software what lengths we wanted in "exact" terms. Its calculation is generally good to 10 sf or better. To scale the drawing properly, you'd have to make the longest side about 23.25 mm, or 0.9152 inches.
