Assume the name of your data frame is flavors_df. What code chunk lets you review the structure of the data frame?
Svetlanka [38]

Assuming the name of your data frame is flavors_df, the code chunk which will allow review of the structure of the data frame is colnames(flavors_df).

<h3>What is Code chunk?</h3>

This is referred to a a runable piece of R code and helps to reduce incidents of mismatch pertaining to the commentary in a paper and the results being discussed.

In the case of a data frame which is flavors_df, the appropriate code chunk is colnames(flavors_df) which allow for extensive review of the item with the barest minimal error which is why it was chosen as the most appropriate choice.

If there are 8 opcodes and 10 registers, a. What is the minimum number of bits required to represent the OPCODE? b. What is the
Nimfa-mama [501]

Answer:  

For 32 bits Instruction Format:

OPCODE   DR               SR1                   SR2      Unused bits

a) Minimum number of bits required to represent the OPCODE = 3 bits

There are 8 opcodes. Patterns required for these opcodes must be unique. For this purpose, take log base 2 of 8 and then ceil the result.

Ceil (log2 (8)) = 3

b) Minimum number of bits For Destination Register(DR) = 4 bits

There are 10 registers. For unique register values take log base 2 of 10 and then ceil the value.  4 bits are required for each register. Hence, DR, SR1 and SR2 all require 12 bits in all.  

Ceil (log2 (10)) = 4

c) Maximum number of UNUSED bits in Instruction encoding = 17 bits

Total number of bits used = bits used for registers + bits used for OPCODE  

     = 12 + 3 = 15  

Total  number of bits for instruction format = 32  

Maximum  No. of Unused bits = 32 – 15 = 17 bits  

OPCODE                DR              SR1             SR2              Unused bits

  3 bits              4 bits          4 bits           4 bits                17 bits

JAVA Question!
dybincka [34]
I don't see any error on your code, everything is well written and simple. Except trying putting PUBLIC on your Class displayer. If you encounter the same problem again try to rebuild your whole code and try to recompile the whole code. Even try restarting your personal computer.

Elements of Server software that is built-in, in Windows workstations are:

1. Hard drives,

3. Processors

4. Network adapters.

Windows Professional OS is not considered a server due to the following:

1. Windows Professional OS has a limit on the number of client connections it allowed.

2. Unlike Server, Professional OS uses less memory

2. In comparison to Server, Professional OS uses the CPU less efficiently

4. Professional OS is not built to process background tasks, unlike Server that is configured to perform background tasks.
