does technology shape society or does society shape technology?

Answers

Answer 1

Answer:

Both. Society creates needs, these needs have to be met. Innovative people then meet the challenge because society says “we’ll compensate you if you can figure this out” and so the race begins. When that technology is developed, and the need is met, the technology inspires society to develop new wants and needs and so the cycle begins anew. Consider the biggest technologies in Human history: The wheel, created ancient civilization because it allowed for transport; The clock and calendar, allowing societies to develop schedules for all of their activities; Writing, allowing information to be passed down accurately from generation to generation; Farming, eliminating the need for civilization to be nomadic; Education systems, allowing for the standards of professionalism to be raised and specialized people to be created; fast-forward to the Industrial Age with the Steam Engine and Coal power plant; fast-forward again to the development of flight; fast-forward again to the atomic bomb and the first computer; etc.

6. What are the general differences between i3, i5, i7, i9 processors?
7. What is the difference in Audio formats like 2.1, 5.1, 7.1, Atmos, and so on? What is the .1?

Answers

1. Choosing accessories depends on the specific needs and requirements of the individual or the purpose of use. Accessories enhance functionality, improve performance, and provide additional features that complement the main equipment.

They can optimize user experience, improve productivity, or cater to specific tasks or preferences.

2. RAM stands for Random Access Memory, a type of computer memory used for temporary data storage and quick access by the processor. DDR3 and DDR4 are different generations or versions of RAM. DDR (Double Data Rate) indicates the type of synchronous dynamic random-access memory (SDRAM). DDR4 is a newer and faster version compared to DDR3, offering improved performance and efficiency.

3. DDR4-3200 refers to the speed or frequency of the RAM. In this case, 3200 represents the data transfer rate of the RAM module in mega transfers per second (MT/s). Higher numbers, such as DDR4-3200, indicate faster RAM with higher bandwidth and improved performance than lower-frequency RAM modules.

4. SSD (Solid-State Drive) and HDD (Hard Disk Drive) are both storage devices but differ in technology and performance. HDDs use spinning magnetic disks to store data, while SSDs use flash memory chips. SSDs are generally faster, more durable, and consume less power than HDDs. However, SSDs are typically more expensive per unit of storage compared to HDDs.

5. Expensive video cards, also known as graphics processing units (GPUs), offer higher performance, better graphics rendering capabilities, and improved gaming experiences. They can handle demanding tasks such as high-resolution gaming, video editing, 3D modeling, and other graphically intensive applications. Expensive GPUs often have more advanced features, higher memory capacities, and faster processing speeds, allowing for smoother gameplay and better visual quality.

6. i3, i5, i7, and i9 are processor models from Intel. Generally, i3 processors are entry-level and offer basic performance for everyday tasks. i5 processors provide a good balance between performance and affordability and are suitable for most users. i7 processors offer higher performance and are better suited for demanding tasks such as gaming and multimedia editing. i9 processors are the most powerful and feature-rich, designed for professional users and enthusiasts who require top-tier performance for resource-intensive applications.

7. Audio formats like 2.1, 5.1, 7.1, and Atmos refer to the configuration of speakers and audio channels in a surround sound system. The number before the dot represents the number of prominent speakers (left, right, center, surround) in the system, while the number after the dot represents the number of subwoofers for low-frequency sounds. For example, 2.1 indicates two main speakers and one subwoofer, 5.1 refers to five main speakers and one subwoofer, and so on. Atmos is an immersive audio format that adds height or overhead channels to create a more

What would you use between the pneumatic and hydraulic system to push heavy objects? Support your statement why you have chosen that system

Answers

Both pneumatic and hydraulic systems can be used to push heavy objects. However, the choice between these two systems depends on several factors, including the specific application, the load capacity, the required force, and the environment.

What is the  hydraulic system?

In general, if the application requires higher force and load capacity, a hydraulic system is typically preferred over a pneumatic system. Hydraulic systems use a liquid, such as oil, to transmit power and can generate higher forces than pneumatic systems, which use compressed air.

Additionally, hydraulic systems are typically more durable and can operate in harsh environments, such as high temperatures and corrosive conditions. They also offer more precise control and can be adjusted to provide a smooth and consistent force.

Explanation:

An iterative design can be defined as a cyclic process which typically involves prototyping, testing, evaluating or analyzing and refining of a product, so as to continually improve the product.

In an iterative design process, the following steps are adopted;

1. A prototype of the product is first created and tested by the manufacturer.

2. The product is then evaluated to check for any defect or flaw.

3. The defect or flaw is fixed through a refining process.

4. The previous steps are repeated incrementally until an improved version of the product is created.

Hence, cycling through the design process to create several models that incrementally improve a solution is called iterative design.

Answer:

Iterative Design

Explanation:

A. It seeks to figure what it defective

Problem Description: Your programs run on a "chip", a CPU. This chip is manufactured on a silicon wafer, a very very thin circular slice of purified silicon with some impurities added to it. A silicon wafer usually has many chips (or dies) created on its surface by automated tools and robots, then at one point in the process the wafer is sliced apart to make individual CPUs (or dies). Your program will do some calculations about these wafers and chips. Follow this link for more information. Given the diameter of the silicon wafer in millimeters
(mm)
, the area of the wafer in square millimeters
(mm 2
) and the area of one individual chip (die) in square millimeters

Note that it should give an integer number of dies (you don't want to cut half a die). Note that the area of the wafer is NOT an input value. You will have to calculate the area of the wafer given the diameter. If you need to, look up the formula for the area of a circle.

Describe the basic internal operation of magnetic hard disc

Answers

Explanation:

Magnetic hard disks (HDDs) are a type of storage device used in computers to store data persistently. Here are the basic internal operations of magnetic hard disks:

Platters: The hard disk consists of several circular disks called platters that are made of a rigid material like aluminum or glass. These platters are coated with a thin layer of magnetic material.

Read/Write Heads: Read/Write Heads are small electromagnets that are positioned above and below each platter. The heads move in unison and are attached to a mechanical arm called the actuator. The actuator positions the heads over the appropriate tracks on the platters.

Spindle Motor: The spindle motor rotates the platters at high speed, typically between 5400 and 15000 revolutions per minute (RPM). The faster the RPM, the faster the hard disk can read and write data.

Magnetic Fields: When data is written to the hard disk, the read/write heads create a magnetic field that aligns the magnetic particles on the platters in a specific pattern, representing the data being written.

Reading Data: When data is read from the hard disk, the read/write heads detect the magnetic pattern on the platters and convert it back into digital data. The read/write heads move rapidly over the platters, reading data from multiple tracks simultaneously.

File System: To organize and manage data on the hard disk, a file system is used. A file system keeps track of the location of data on the hard disk, as well as other information such as file names, permissions, and timestamps.

Answers

Brainy's issue is most likely due to a shortage of RAM.

How can this be explained?

The computer's limited 3 GB of RAM may pose a challenge in managing numerous operations, and consequently may heavily depend on virtual memory, causing heightened hard drive activity and a reduction in overall efficiency.

My suggestion to resolve this issue would be to enhance the RAM. By adding more RAM to the computer, its memory capacity will enhance, leading to a reduction in dependence on virtual memory and an enhancement in overall efficiency, as it will be able to stock and access a greater amount of data.

Hi!
i want to ask how to create this matrix A=[-4 2 1;2 -4 1;1 2 -4] using only eye ones and zeros .Thanks in advance!!

Answers

The matrix A=[-4 2 1;2 -4 1;1 2 -4] can be created by using the following code in Matlab/Octave:

A = -4*eye(3) + 2*(eye(3,3) - eye(3)) + (eye(3,3) - 2*eye(3))

Here, eye(3) creates an identity matrix of size 3x3 with ones on the diagonal and zeros elsewhere.

eye(3,3) - eye(3) creates a matrix of size 3x3 with ones on the off-diagonal and zeros on the diagonal.

eye(3,3) - 2*eye(3) creates a matrix of size 3x3 with -1 on the off-diagonal and zeros on the diagonal.

The code above uses the properties of the identity matrix and the properties of matrix addition and scalar multiplication to create the desired matrix A.

You can also create the matrix A by using following code:

A = [-4 2 1; 2 -4 1; 1 2 -4]

It is not necessary to create the matrix A using only ones and zeroes but this is one of the way to create this matrix.

What is the value of the variable result after these lines of code are executed?

>>> a = 10
>>> b = 2
>>> c = 5
>>> result = a * b - a / c
The value of the variable is
.

Answers

Answer:

18

Explanation:

If you take the formula, and you substitute the values of the variables, it will be:

    10 * 2 - 10 / 5

Then if you remember the order of math operations, it will be:

    (10 * 2) - (10 / 5)

Which reduces to:

    20 - 2 = 18

The value of the variable result is 18

The code is represented as follows:

Python code:

a = 10

b = 2

c = 5

result = a * b - a / c

Code explanation;The variable a is initialise to 10The variable b is initialise to 2Lastly, the variable c is initialise to 5

Then the arithmetic operation  variable a multiplied by variable b minus  variable a divided by variable c is stored in the variable "result".

Printing the variable "result" will give you 18.

Build a sequence detector for the following binary input sequence: 000, where the left-most binary input happened first. The sequence detector should detect all instances of the target sequence by outputting 1 when the sequence is detected and when the sequence is not detected. Example, a sequence detector for the different sequence 1101 should have the following pattern. IN : 0 1 1 0 1 1 0 1 0 1 OUT: 0 0 0 0 1 0 0 1 0 0 The 1-bit input to this sequence detector is called i. The 1-bit output to this sequence detector is called

Answers

A sequence detector for the binary input sequence "000" can be implemented using a three-bit shift register and a combinational circuit that checks for the desired sequence.

The three-bit shift register will hold the three most recent bits of the input sequence, with the most recent bit in the rightmost position. The combinational circuit will check whether the contents of the shift register match the desired sequence "000".

The implementation of the sequence detector using a shift register and a combinational circuit can be described as follows:

i) Initialize the shift register with all zeros.

ii) For each input bit i:

a. Shift the contents of the shift register one bit to the left.

b. Store the new input bit i in the rightmost position of the shift register.

c. Check whether the contents of the shift register match the desired sequence "000". If the contents of the shift register match the desired sequence, output a 1. Otherwise, output a 0.

iii) Repeat step 2 for each subsequent input bit.

iv) The implementation of the sequence detector can be shown using a state diagram or a truth table. Here is the truth table for the sequence detector:

In this truth table, the "Current State" column represents the current contents of the shift register, the "Input i" column represents the current input bit, the "Next State" column represents the new contents of the shift register after shifting and storing the new input bit, and the "Output o" column represents the output of the sequence detector.

Using this truth-table, we can implement the combinational circuit that checks for the desired sequence, and then build the sequence detector using a shift register and the combinational circuit.

Which octet of the subnet mask 255.255.255.0 will tell the router the corresponding host ID?

Answers

Answer: The last octet

Explanation: The last octet of the subnet mask will tell the router the corresponding host ID.

The last octet is the octet of the subnet mask 255.255.255.0 will tell the router the corresponding host ID.

What is octet in IP address?

An octet is a decimal value between 0 and 255, and it is referred to as x in the IPv4 component of the address. The octets are separated by periods. The IPv4 portion of the address must contain three periods and four octets.

People may have also heard people refer to the four digits that make up an IP address as "octets." An octet is the correct term to describe the four different digits that make up an IP address.

In subnetting, the third octet is used to identify particular subnets of network 150.150.0.0. Each subnet number in the example in the image has a different value in the third byte, indicating that it is a distinct subnet number.

Thus, it is last octet.
