Difference between Hollerith and Burroughs machine
Answers
Explanation:
The tabulating machine was an electromechanical machine designed to assist in summarizing information stored on punched cards. Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census. Later models were widely used for business applications such as accounting and inventory control. It spawned a class of machines, known as unit record equipment, and the data processing industry.
Herman Hollerith (February 29, 1860 – November 17, 1929) was an American businessman, inventor, and statistician who developed an electromechanical tabulating machine for punched cards to assist in summarizing information and, later, in accounting. His invention of the punched card tabulating machine, patented in 1884, marks the beginning of the era of mechanized binary code and semiautomatic data processing systems, and his concept dominated that landscape for nearly a century.
Hollerith founded a company that was amalgamated in 1911 with several other companies to form the Computing-Tabulating-Recording Company. In 1924, the company was renamed "International Business Machines" (IBM) and became one of the largest and most successful companies of the 20th century. Hollerith is regarded as one of the seminal figures in the development of data processing.

What are the values for ss and variance for the following sample of n = 3 scores? sample: 1, 4, 7 mean = 4
Answers
The values for ss and variance for the following sample of n = 3 scores are 18 , 9 respectively.

Difference between each score and mean:

7-4 = 3
List of squared difference: 9, 0, 9
Sum of squared difference: 9+0+9 = 18
Variance = SS/n-1 = 18/2 = 9
SS, often known as the sum of squares or just SS, stands for the sum of squared deviations from the mean and is a crucial concept in statistics.

I own a SanDisk flash drive, and I want to download pictures on it so I can plug into my tv and use them for art references, but when I put the flash drive into my tv, and when I clicked on an image, it say that, "the files are unsupported."
Any idea what that means, and how I can fix it?

Answers
Answer: Try opening it with another app on the TV, but if that does not work try connecting a USB flash drive to the USB connector that is built into Smart TV. It can be located on the back, side, or front panel. Find a suitable connector on your TV, install the USB stick into the connector, take the TV remote control, and select the desired folder in the file system.
Try using a different USB drive, format the current Flash drive with the right format (such as FAT32) then paste, or save the supported file again. If other files do not play, perform a reset.
Make sure that the USB drive is fully inserted into the USB input of the player.
Make sure that the file being used is one of the supported file types. A list of the supported file types is available in the operations guide.
Attempt to play a different file.
If other files play, there may be an issue with the file itself. Try removing the file from the USB drive and saving a new copy.
IMPORTANT: If the file being used is corrupted or was recorded using an unsupported codec, the player will not be able to play the file.

Answers
Yes, the programmer must have written 30 or more lines of code on at least one day.
When the programmer wrote 30 or more lines of code? why?Given data
Total Lines of code= 500
Number of days= 17 days
Number of codes written per day= 500/17
Number of codes written per day= 29.4117
If we multiply 29.4117 by 17
=499.9989
=500 approx
Hence there was never a day when the programmer wrote 30 or more linesThe programmer must have written 30 or more lines of code on at least one day. This is due to the fact that an average of 29.4 lines of code per day equals 500 lines of code divided by 17 days. The programmer must have written at least 30 lines of code on one of the days (and potentially more), as it is impossible to have less than one line of code, in order to have 500 lines of code in total after 17 days.To learn more about Number of codes written per day refer to:

There are n candidates, where each candidate has a skill denoted by skill[i]. A total of ( n/2) teams are to be formed, such that the total skill of each team is the same. The efficiency of a team is defined as the product of the skill levels of its two members, i.e., for the-skills [1, 3], the efficiency of the team is 1∗3=3. Find the sum of efficiencies of all teams that can be formed satisfying the criteria. If there is no way to create teams that satisfy the conditions, return −1. Note: It can be shown that the answer is always unique. Example The skills of the candidates are skill =[1,2,3,2]. They can be paired as [[1, 3], [2, 2]].

Answers
When you dereference an object pointer, use the -> operator.
What is pointer?
A pointer is a variable in a computer program that stores the address of another variable. This allows the program to access the data stored in the other variable without having to know the exact address of the data. Pointers are an important concept in programming, as they allow for efficient use of memory and more complex data structures. Pointers can simplify tasks such as looping, searching, and sorting. They can also make it easier to debug programs, as the address of a variable can be tracked through the pointer. Pointers can also be used to implement dynamic memory allocation, which can be used to create more efficient programs. Pointers are often used in C and C++ programming languages, but have been adapted for use in other languages as well.

nadine is the systems administrator for a network with a single subnet. The subnet uses 192.168.1.0 with a mask of 255.255.255.0. The network has 10 servers running Windows Server. Srv1 currently provides both DHCP and DNS services. Nadine wants to increase the fault tolerance for her DHCP servers. She installs a new server, Srv11, and configures it for DHCP. She configures a scope on Srv11 to match the scope on Srv1 and then excludes half of the addresses in the scope on Srv1 and the other half of the addresses on the Srv11. Nadine decides to test her solution and shuts down Srv1. As a test, she forces a workstation to release its IP address and request a new one. She finds that the workstation has the IP address 169.254.0.15 with a mask of 255.255.0.0. What should Nadine do to fix the problem?
Answers
Answer:
Authorize Srv11
Explanation:
In order to fix this problem, Nadine should Authorize Srv11. The problem is most likely being caused due to failure of authorization of the server. This would prevent this server from being on the same scope as Srv1 and therefore, it is why the IPaddress being given is different. DHCP is an automatic protocol and would not be able to provide an IP address in the same scope if the server is not Authorized to do so.

A. *a;
B. a;
C. &a;
D. address( a );
Answers
The memory location of integer variable an is provided by &a;. The type of the variable an is integer, not integer pointer. Therefore, we utilise &a to obtain its address.
Variable and other data are kept in the main memory (sometimes referred to as the memory) while a programme is running. The computer's memory appears to a programme as a set of bytes, each of which has an integer address. For instance, there are bytes with addresses 1, 2, and so on, all the way up to a very big number. A software has the ability to get the byte's current contents at a certain memory location and write a specific value in that byte.
Only 8 bits make up a byte. The majority of the data pieces you employ are bigger than that. For instance, an int value typically has 32 bits, or 4 bytes, of space.
