An OpenCL Device is composed of: Group of answer choices Command Queues Platforms Processing Elements Compute Units
Answer:
Compute Units
Explanation:
A platform can be defined as a computing environment for building and executing sets of code in a software application or program such as an application programming interface (API).
The two parts of the platform used to run an application software are both hardware and software (operating system).
Machine and assembly are referred to as a low level programming language used in writing software programs or applications with respect to computer hardware and architecture. Machine language is generally written in 0s and 1s, and as such are cryptic in nature, making them unreadable by humans but understandable to computers.
OpenCl is an abbreviation for open computing language that runs on CUDA-powered graphics processing units (GPUs). An OpenCL Device is composed of compute units and an OpenCl compute unit typically comprises of processing elements.
Describe a cellular network, its principle
components and how it works.
A cellular network is a contact network with a wireless last connection. The network is divided into cells, which are served by at least one fixed-location transceiver station each. These base stations provide network coverage to the cell, which can be used to send voice, data, and other types of information. It's often referred to as a mobile network.
The principal components of the cellular network will be explained below as follows-
BTS (Base Transceiver Station) - It is the most important part of a cell since it links subscribers to the cellular network for data transmission and reception. It employs a network of antennas that are dispersed across the cell.
BSC (Basic Station Controller) - It is a portion that interfaces between Basic Station Controllers and is connected to Basic Station Controllers via cable or microwave links, as well as routing calls between Basic Station Controllers and the MSC (Mobile Switching Center).
MSC (Mobile Switching Center) - The supervisor of a cellular network is linked to several Basic Station Controllers and routes cells between them. It also connects the cellular network to other networks such as the PSTN through fiber optics, microwave, or copper cable.
A cellular network works when the SIM card is organized into geographical cells, each of which has an antenna that transmits to all mobile phones in the city, cellular networks operate by knowing the exact location, which comes from the SIM card. A transmitter generates an electrical signal, which is converted by the transmit antenna into an electromagnetic wave, which is then radiated, and the RF wave is then converted back into an electrical signal. In cellular network networks, four multiple access schemes are used, ranging from the first analog cellular technologies to the most modern cellular technologies.
Create a dynamic array of 100 integer values named myNums. Use a pointer variable (like ptr) which points to this array. Use this pointer variable to initialize the myNums array from 2 to 200 and then display the array elements. Delete the dynamic array myNums at the end. You just need to write part of the program.
Answer:
The required part of the program in C++ is as follows:
int *ptr;
int *myNums = new int(100);
srand (time(NULL));
for (int i = 0; i < 100; i++) {
myNums[i] = rand() % 200 + 2; }
ptr = myNums;
cout << "Output: ";
for (int i = 0; i < 100; i++) {
cout <<*(ptr + i) << " "; }
delete[] myNums;
Explanation:
This declares a pointer variable
int *ptr;
This declares the dynamic array myNums
int *myNums = new int(100);
This lets the program generate different random numbers
srand (time(NULL));
This iterates through the array
for (int i = 0; i < 100; i++) {
This generates an integer between 2 and 200 (inclusive) for each array element
myNums[i] = rand() % 200 + 2; }
This stores the address of first myNums in the pointer
ptr = myNums;
This prints the header "Output"
cout << "Output: ";
This iterates through the pointer
for (int i = 0; i < 100; i++) {
Print each element of the array, followed by space
cout <<*(ptr + i) << " "; }
This deletes the dynamic array
delete[] myNums;

The Internet, sometimes called simply "the Net," is a worldwide system of computer networks -- a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers).
When adding several user accounts, you might want to use the newusers utility, which can process a text file full of entries to add user accounts. Use the man or info page to find out how to use this utility, and use it to add three users. When finished, view the /etc/passwd, /etc/shadow, and /etc/group files to verify that the users were added successfully.
Explanation:
Given - When adding several user accounts, you might want to use the new users utility, which can process a text file full of entries to add user accounts.
To find - Use the man or info page to find out how to use this utility, and use it to add three users.
Proof -
New Users Utility:
It is an utility which reads the file full of usernames and clear text passwords.
It then uses this information to update a group of the existing users to create new users.The format of the file consists of specified things like:
pw - passwd
pw - age
pw - gid
pw - dir
Use of the Utility:
The command is new users filename
The file should look like -
(Username : Password : UID : GID : User Information : Home Directory : Default Shell)
where ,
UID = User Identifier
GID = Group Identifier
Testing the Users:
Creating users from the file given above test User 1, directory Of File
Executing the create user new users directory Of File
Repeat this step to undergo all the users that are been noted down in the file to make them a user in the noted group policy.
Hence,
These are the steps of using the new Users utility.

You designed a program to create a username using the first three letters from the first name and the first four letters of the last name. Usernames cannot have spaces. You are testing your program with a user whose name is Jo Wen. What step in the program plan do you need to revisit
Answer:
See Explanation
Explanation:
The question would be best answered if there are options to select from; since none is provided, I will provide a general explanation.
From the question, we understand that, you are to test for Jo Wen.
Testing your program with this name will crash the program, because Jo has 2 letters (3 letters are required), and Wen has 3 letters (4 letters are required)
So, the step that needs to be revisited is when the username is generated.
Since the person's name cannot be changed and such person will not be prevented from registering on the platform, you need to create a dynamic process that handles names whose lengths are not up to the required length.

Explanation:
Imagine running a 64-bit system on a 32-bit system, where we simulate a single 64- bit memory location (register) using two atomic 32-bit memory locations (registers). A write operation is implemented by simply writing the first 32-bits of the simulated 64-bit register in the first real register, then the second 32-bits in the second real register. A read, similarly, reads the first half from the first register, then the second half from the second register, and returns the concatenation. What is the strongest property that this 64-bit register satisfies: safe, regular, or atomic
Answer:
It's not possible to ensure memory access occurs indivisibly when it has to broken into multiple operations. Unfortunately, the fact that your application is running on a 64-bit kernel does not change the equation any - it is actually running in a compatibility layer and has none of the benefits of x64

Arrays of structures ________. Group of answer choices None of the above. are automatically passed by reference cannot be passed by reference are automatically passed by value
Answer:
are automatically passed by reference.
Explanation:
A parameter can be defined as a value that can be passed to a function. Thus, a parameter refers to a value that must be passed into a function, subroutine or procedure when it is called.
This value can be passed to a function either by reference or by value.
This ultimately implies that, parameter variable stores information which is passed from the location of the method call directly to the method that is called by the program.
Basically, parameters can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function.
In Computer programming, an array can be defined as data structure which comprises of a fixed-size collection of variables each typically holding a piece of data and belonging to the same data type such as strings or integers.
This ultimately implies that, when a programmer wishes to store a group of related data (elements) of the same type, he or she should use an array.
A character positions in arrays start counting with the number 0 not 1.
Hence, an array uses a zero-based indexing and as such the numbering or position of the characters (elements) starts from number 0. Thus, the first character (element) in an array occupies position zero (0), the second number one (1), the third number two (2) and so on.
Generally, arrays of structures are automatically passed by reference through the use of a REPLICATE function.
Why do organizations need to tailor project management concepts, such as those found in the PMBOK® Guide, to create their own methodologies?
Explanation:
Although each project is different and unique, according to the Method Statement of PMBoK, customising is required. Not that every procedure, tool, methodology, input, or output listed in the PMBoK Guide is mandated for every project. Scope, timeline, cost, materials, quality, and danger should all be considered while tailoring.

A network consists of 75 workstations and three servers. The workstations are currently connected to the network with 100 Mbps switches, and the servers have 1000 Mbps connections. Describe two network problems that can be solved by replacing the workstations' 100 Mbps switches and NICs with 1000 Mbps switches and NICs. What potential problems can this upgrade cause
Answer:
A) i) starvation ii) flow control
B) Network congestion
Explanation:
A) Network problems that can be addressed / solved
By replacing the workstations 100 Mbps switches with 1000 Mbps switches the problem of
Starvation; been faced by the servers due to the delay in sending data to be processed by the servers from the workstations will be resolved .
Flow control : The huge difference in the speeds of the workstations and servers causes a network buffer which leads to packet loss therefore when the workstations 100 Mbps switch is replaced with 1000 Mbps switch this network problem will be resolved
b) The potential problem that can be encountered is Network Congestion
1-How many moles of NazCOs are in 10.0 ml of a 2.0 M solution?
Answer:
A solution is a mixture in which the particles are so small that the components are indistinguishable from each other. The amount of the solute and the solvent in a solution can be expressed in terms of different concentration expressions such as molarity, morality, etc.
Explanation:
To calculate the number of moles of sodium carbonate, the volume in liters will be multiplied by the molar concentration of the solution.
moles Na2CO3 = 2.0 M x 0.0100 L = 0.020 moles Na2CO3
Hope it helps :)
Answer:
There are 20. mol of Na2CO3 in 10.0L of 2.0M solution.
Explanation:
Molarity is represented by this equation:
(look at attachment)
In our case, we already have the molarity and volume of solution, both of which have good units.
Let's rearrange the equation to solve for the number of moles. We can do this by multiplying by L solution on both sides of the equation. The L solution will cancel out on the right side, leaving the number of moles being equal to the molarity times volume:
Moles of solute
=Lsolution×Molarity
Now we just plug the known values in!
Moles of solute = (10.0 L) (2.0M) = 20. moles

Which term refers to a cloud-native, streamlined technology for hosting cloud-based applications, where a server runs for short bursts only when needed by an application or service
Answer:
Serverless computing.
Explanation:
Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.
Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.
Cloud computing comprises of three (3) service models and these are;
1. Platform as a Service (PaaS).
2. Infrastructure as a Service (IaaS).
3. Software as a Service (SaaS).
The three (3) main characteristics of cloud computing are;
I. Measured service: it allows cloud service providers to monitor and measure the level of service used by various clients with respect to subscriptions.
II. Resource pooling: this allows cloud service providers to serve multiple customers or clients with services that are scalable and provisional.
III. Elasticity: this is the ability of the cloud computing service to be flexible and adaptive to the traffic or requests from the end users.
Serverless computing is a term which refers to a cloud-native and streamlined technology that is designed typically for hosting cloud-based applications, in which a server operates for short bursts only when needed by an application or service. Serverless computing is used for the allocation of machine resources on demand.

Explanation:
1. Redundant batch of Inexpensive Drives (or Disks) (RAID) is a term for data storage schemes that divide and/or replicate data amid multiple hard drives.
2. RAID can be designed to provide increased data accuracy or increased Input/Output performance
Hardware RAID exists as a customized processing system, utilizing various controllers or RAID cards to control the RAID design independently from the OS. Software RAID utilizes the processing capacity of that computer's operating system in which the RAID disks exists installed.
What are the two types of RAID?
We have two kinds of RAID implementation through. Hardware and Software. Both these implementation contains its own benefits and drawbacks.
Software RAID does not count any cost for a RAID controller and exists fairly effortless to estimate the cost of as you exist only buying additional drives. All of our usual dedicated servers come with at least two drives, indicating there exists NO cost for software RAID 1, and stands positively suggested. It exists positively suggested that drives in a RAID array be of the exact type and size. With RAID 0 or RAID 1, you'd require at least two drives, so you would require to buy one additional drive in most cases. With RAID 5 you'll require at least three drives, so two additional drives, and with RAID 6 or 10 you'd require at least four total drives. To earn additional implementation, redundancy, or disk space, you can count more disks to the collections as well.

Write function d2x() that takes as input a nonnegative integer n (in the standard decimal representation) and an integer x between 2 and 9 and returns a string of digits that represents the base-x representation of n.
Answer:
The function in Python is as follows:
def d2x(d, x):
if d > 1 and x>1 and x<=9:
output = ""
while (d > 0):
output+= str(d % x)
d = int(d / x)
output = output[::-1]
return output
else:
return "Number/Base is out of range"
Explanation:
This defines the function
def d2x(d, x):
This checks if base and range are within range i.e. d must be positive and x between 2 and 9 (inclusive)
if d >= 1 and x>1 and x<=9:
This initializes the output string
output = ""
This loop is repeated until d is 0
while (d > 0):
This gets the remainder of d/x and saves the result in output
output+= str(d % x)
This gets the quotient of d/x
d = int(d / x) ----- The loop ends here
This reverses the output string
output = output[::-1]
This returns the output string
return output
The else statement if d or x is out of range
else:
return "Number/Base is out of range"
