What are the different types database of end users? Discuss the main activi-ties of each
Answer:
following types of databases available in the market −
Centralised database.
Distributed database.
Personal database.
End-user database.
Commercial database.
NoSQL database.
Operational database.
Relational database.
Cloud database.
Object-oriented database.
Graph database
Answer:
1. Casual End Users
These are the users who occasionally access the database but they require different information each time. They use a sophisticated database query language basically to specify their request and are typically middle or level managers or other occasional browsers. These users learn very few facilities that they may use repeatedly from the multiple facilities provided by DBMS to access it.
2. Naive or parametric end users
These are the users who basically make up a sizeable portion of database end users. The main job function revolves basically around constantly querying and updating the database for this we basically use a standard type of query known as canned transaction that have been programmed and tested. These users need to learn very little about the facilities provided by the DBMS they basically have to understand the users’ interfaces of the standard transaction designed and implemented for their use. The following tasks are basically performed by Naive end users:
The person who is working in the bank will basically tell us the account balance and post-withdrawal and deposits.
Reservation clerks for airlines, railway, hotels, and car rental companies basically check availability for a given request and make the reservation.
Clerks who are working at receiving end for shipping companies enter the package identifies via barcodes and descriptive information through buttons to update a central database of received and in transit packages.
3. Sophisticated end users
These users basically include engineers, scientist, business analytics and others who thoroughly familiarize themselves with the facilities of the DBMS in order to implement their application to meet their complex requirement. These users try to learn most of the DBMS facilities in order to achieve their complex requirements.
4. Standalone users
These are those users whose job is basically to maintain personal databases by using a ready-made program package that provides easy to use menu-based or graphics-based interfaces, An example is the user of a tax package that basically stores a variety of personal financial data of tax purposes. These users become very proficient in using a specific software package.

Attackers have taken over a site commonly used by an enterprise's leadership team to order new raw materials. The site is also visited by leadership at several other enterprises, so taking this site will allow for attacks on many organizations. Which type of malicious activity is this?
A rootkit is a malware-style terminology designed to infect an attacker's target PC and allow them to install many tools that use him for persistent wireless connectivity to the system.
It is an illegal computer program to enable continuous privileged access to a computer and hide its presence actively. In today's life, it often conceals their existence and actions from uses and other functionality of the system, especially spyware - for instance, trojans, worms, viruses.That's why the rootkit is employed since it is developed in this case to access Victin's system at an administrator level.

Answer and explanation:
1. It asks for the total expenses for the month of March. So, let's add all of the March expenses up.
1,600 + 2,100 + 850 + 480 + 2,800 = $7,830 (which is the answer)
2. It asks what the highest expense for wages are. That would be $5,080. Out of all of the times that the wages have been paid, in April, it was the highest, at $5,080. So, $5,080 is the answer.
3. It asks how many items cost less than $1,000 in April. The only thing that cost less than $1,000 in April was the water because it only cost $370. So, the answer would be 1.
Hope this helps!

Note: Using a pre-defined string function, the solution can be just one line of code.
(I tried using strVar.insert(partStr, str2) but was unsuccessful. I don’t know where I’m messing up. Thank you for your help. I’ve been trying to alter this code for a while now)
Answer:
Use the .find() function in your first string to give you an index.
Explanation:
Hi! I'm guessing you're taking COP2334 like me. A T.A. helped me figure out what I needed, so I'm passing it on.
Basically, you're given three strings and no integer to use as an index in order to insert the second line. Since you are required to have an index to use the .insert() function, this is "tear-out-my-hair" frustrating. What I failed to remember was that it is totally possible to use a function inside another function to get what you need!
You have been given is a hint as to where str2 goes, in the form of your 3rd string. If I'm right, all of the tests the system will run (mine is in Zybooks) will give a 3rd string that is inside the first string.
String 1: strVar: "FuzzyBear"
String 2: str2: "Wuzzy"
String 3: partStr "Be"
Open your statement with strVar and use the insert.() function. In the insert function, you are required to give a place to start, (your index), then what you want to insert. Your index will be the .find() function, searching in StrVar for partStr. The second part of the .insert() function is str2.

When we say that communication is relational, what does that mean?
a. Communication is key to greater satisfaction in relationships.
b. Communication involves a wide range of socially appropriate behaviors.
c. Communication is something that we do to others.
d. Communication arises out of our interactions with others.
Answer:
a
Explanation:
Without communication there's nothing we can do .
Relational interaction includes the processes of interaction in personal relationships like romantic relations, family ties, and friendships, and further discussion can be defined as follows:
It consists of negotiating processes by which the dyadic partners define who they are and they will collaborate. This relation perspective assumes that the pair is indeed the best unit for interpersonal communication observation.Therefore, the final answer is "Option a".

For those of u who watch Lucifer- S6 is coming out on Sept 10th
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.

Suppose 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
