The output signal from an analogue sensor is sampled every 195 µs to convert it into a digital representation. What is the corresponding sampling rate expressed in kHz?
According to the Sampling Theorem, for this sampling rate value, what approximately could be the highest frequency present in the signal, in kHz, assuming the lowest frequency is very close to zero?
If each sample is now quantised into 512 levels, what will be the resulting bitrate in kbps?
Give your answer in scientific notation to 2 decimal places.
Hint: you need to determine the number of bits per sample that produces 512 quantisation levels.
Answer:
A sample rate is just reciprocal of the sample period. According to sampling theorem the highest frequency in single would be [tex]5.13/2=2.565 KHz.[/tex][tex]2^8=512[/tex] So you will need 8 bits to represent.[tex]8 bits \times5.128\times(10)^3[/tex]samples [tex]=41.026[/tex] bits per second.Explanation:
Sample period of 1 millisecond [tex]=1 kHz.[/tex]
Thus a sample period of [tex]0.195[/tex] milliseconds is
[tex]1/0.195=5.12820513 Hz[/tex]
To determine the sample after [tex]512[/tex] levels quantization, we need to find bits per sample that produces [tex]512[/tex] quantization levels.
Thus,
[tex]2^8=512[/tex]
So you will need 8 bits to represent.
8 bits [tex]\times5.128\times(10)^3[/tex] samples [tex]=41.026[/tex] bits per second.

What the central difference between negative and positive politeness?
Answer:
Politeness is universal, resulting from people's face needs: Positive face is the desire to be liked, appreciated, approved, etc. Negative face is the desire not to be imposed upon, intruded, or otherwise put upon.
Positive face refers to one's self-esteem, while negative face refers to one's freedom to act. Participants can do this by using positive politeness and negative politeness, which pay attention to people's positive and negative face needs respectively.
What are positive face needs?One's face need is the sense of social value that is experienced during social interactions. Positive face refers to the need to feel accepted and liked by others while negative face describes the will to do what one wants to do with freedom and independence.
Negative politeness :
Making a request less infringing, such as "If you don't mind" or "If it isn't too much trouble"; respects a person's right to act freely. In other words, deference. There is a greater use of indirect speech acts.
What is politeness in discourse analysis?In sociolinguistics and conversation analysis (CA), politeness strategies are speech acts that express concern for others and minimize threats to self-esteem ("face") in particular social contexts.

State the major different between fours types of computers
Answer:
1. Supercomputers
Supercomputers are very expensive and very fast. They are the most powerful computers we have in the world.
Supercomputers are optimized to execute only a small number of programs. This makes it possible for them to execute these few programs at a very high speed. Due to their inhibiting cost, they are used in high-end places like in scientific research centers. The supercomputer consists of thousands of processors, allowing it to clock in at very high speeds measured by petaflops.
These computer types are also very large in size due to the numerous parts and components involved in their design.
A good example of a supercomputer is Tianhe-2, which is located in the National Supercomputer Center in Guangzhou, China. It features 3.12 million cores, allowing it to run at speeds of 33.86 petaflops.
2. Mainframe Computers
These are large and expensive computers that are capable of supporting thousands of users simultaneously. They are mostly used by governments and large organizations for bulk data processing, critical applications, and transaction processing. They are ranked below supercomputers.
3. Minicomputers
Minicomputers are mid-sized computers. In terms of size and power, they are ranked below mainframes. A minicomputer is a multiprocessing system capable of supporting from 4 to about 200 users simultaneously.
The use of the term minicomputer has diminished since the introduction of microprocessors. These machines are now more commonly called midrange computers.
4. Microcomputers
A microcomputer, also known as a personal computer, is designed to be used by one user at a time. The term microcomputer relates to the microprocessor that is used for the purpose of processing data and instruction codes. These are the most common computer types since they are not very expensive

Worksheet-I • Make a list of 10 application software and 5 utility programs installed in your computer, along with their uses. Uses Applications Type
Answer:
An antivirus is a utility software that helps to keep the computer virus-free. Moreover, it notifies when any malicious file is detected and removes such files. In addition, it scans any new device attached to the computer and discards any virus if there. Moreover, it also scans the system from time to time for any threats and disposes of them. Examples of antivirus are McAfee Antivirus, Quick heal Antivirus, Windows Defender, etc.
These utility software are used to manage files of the computer system. Since files are an important part of the system as all the data is stored in the files. Therefore, this utility software help to browse, search, arrange, find information, and quickly preview the files of the system.
An important part of a computer is storage space, it is very important to maintain this storage. Therefore, we use certain utility software to compress big files and decrease their size, these are compression tools. The format of the files changes while compressing and we cannot access or edit them directly. In addition, we can easily decompress the file and get the original file back. Examples of compression tools are WinZip, WinRAR, 7-Zip, etc.
These utility software are used to manage data on disks. Moreover, they perform functions like partitioning devices, manage drives, etc. Examples of disk management tools are Mini Tool Partition Wizard, Paragon Partition Manager, etc.
This utility software helps to free up the disk space. In addition, the files which are no longer in use are removed from the disk. Examples are Cortex, C Cleaner, etc.

In what ways are computers being used to improve our quality of life
Answer:
computers help with our education systemcommunicating with others is easier (emails/text messages opposed to sending an envelope)technological advancesSuppose now the file is broken up into 1000 packets with each packet
containing 4,000 bits. Suppose that each packet is acknowledged by the
receiver and the transmission time of an acknowledgement packet is
negligible. Finally, assume that the sender cannot send a packet until the
preceding one is acknowledged. How long does it take to send the file?
Answer:
The delay to send each packet will be ttrans + tprop. However there is an additional tprop delay for the acknowledgement packet to arrive at the sender, prior to which the next packet can be transmitted. Hence the total delay to transmit 10 packet is = 10 * (ttrans + 2 tprop) = 10*(40 msec + 80 msec) = 1.2 sec
Explanation:
Research the trend of BYOD in workplaces. Compare the advantages to any potential disadvantages. Do you think more companies should adopt this policy? Why or why not?
Answer:
please mark me brainlist
Explanation:
Bring Your own Device (BYOD) refers to bringing the personal devices on the place where the employees work for the company, as in by accessing the data, systems etc of the company. It is becoming rapidly popular in the traditional workplaces.
Likely we are saying as BYOD is rapidly growing organisation so it is having some advantages and disadvantages.
ADVANTAGES are as follows:-
1) If a company is linked with the byod organisation, this will help in reducing the cost of the devices, as in they do not have to purchase them. In addition to take care of their own devices, employees are generally more likely to do so.
2) With the help of BYOD the productivity of the employees also increases and the reason behind is that the employees or the users are more likely to be more familiar and comfortable with their own devices, to be use by personal. Users or the employees are expert in the navigation and how to use the device policy as they known their own devices very well. Devices are known to them which help to execute the work with more ease. This also leads to make their interest in work continously for long. Another big thing is the User Satisfaction. Users are more satisfy with the device they choose by own for the respective work as compare to the devices that are selected for them.
3) Users can work day and night all along as the devices are their own. They can check their mails, work on them etc in late nights just because of they are having their own devices. Great Flexibility are offered by the BYOD programs. They provide an ease for working anywhere at any place by using the mobile at any time. By the increase in the flexibility, company are more likely to attract top-performing employees from various places.
DISADVANTAGE:-
1) As employees are using their own personal devices so it is quite difficult to manage the security in the respective device, that's why Security become one of the major disadvantage of the BYOD programs. Employees are accessing the sensitive information on the devices that are not fully secure. Whenever the owns a device particularly, they explain how the device will use by blocking some sites, monitoring the activity if needed. One of the biggest security related challenge is to make sure that all the personal devices are fully secured from the external attacks, malware and if they are connected to the internet privately or publicly in the world.
2) BYOD own the devices hence, they are having the benefit to select a small number of devices to support. This will be easier on the IT department as they can become familiar with the devices. It will be more difficult to immediately download software updates and security.
3) Another issue of BYOD programs is of scalability. Employees in the organization uses personal devices, which is not want by any organizations as simply they don’t have the big network infrastructure to handle all of the traffic burden.
In my opinion bring your own device policy would not be accepted by the companies because company follow a client policy that is employee has to do the work for the client and company have to save there client from employee as many employee wants to start there own company so they bought client from the existence company which is a loss to company and it would became very easy for the employee if BYOD comes to play as they can carry data of the client.
BYOD exists an acronym for “Bring Your Own Device.” It directs to the practice of employees utilizing a personal device for work.
What is BYOD?
Bring Your own Device (BYOD) directs to obtaining personal devices in the area where the workers work for the company, as in by accessing the data, systems, etc of the company. It exists evolving rapidly famous in the traditional workplaces.
Advantages OF BYOD
Employees might become better productive since they remain related to the company.Employees no longer must be in the company’s office to work.The company declines its expenditures by lowering hardware assets.The “freedom” of BYOD can improve employee confidence.Disadvantages OF BYOD
Employees may not have sufficient antivirus software, firewalls, or other technological protection software established on their appliances.Devices utilized by employees stand vulnerable to theft, loss, or harm.Employees often work at outside Wi-Fi sites that exist not protected and stand vulnerable to strikes by others.Some employees may be utilizing certain software systems that exist not consistent.The employee utilizes his or her instrument for personal reasons while on firm time, reducing productivity.To learn more about BYOD
