To convert the given grammar into Chomsky Normal Form (CNF), we need to rewrite the rules and ensure that each production has only two non-terminals or one terminal on the right-hand side. Here is the converted CNF grammar:

1. S → SS | AB | B

2. A → AA

3. A → a

4. B → bBb | bb | ε

5. C → CC | a

6. D → aC | bb

Explanation:

1. The production S → SS has been retained as it is.

2. The production A → aAAa has been split into A → AA and A → a.

3. The production B → bBb has been split into B → bB and B → b.

4. The production B → bb has been kept as it is.

5. The production B → ε (empty string) has been denoted as B → ε.

6. The production C → CC has been retained as it is.

7. The production C → a has been kept as it is.

8. The production D → aC has been kept as it is.

9. The production D → bb has been kept as it is.

In summary, the given grammar has been converted into Chomsky Normal Form (CNF), where each production has either two non-terminals or one terminal on the right-hand side. This form is useful in various parsing and analysis algorithms.

Answer:

Explanation:

To convert the given grammar to Chomsky Normal Form (CNF), we need to follow a few steps:

Step 1: Eliminate ε-productions (productions that derive the empty string).

Step 2: Eliminate unit productions (productions of the form A → B).

Step 3: Convert long productions (productions with more than two non-terminals) into multiple productions.

Step 4: Convert terminals in remaining productions to new non-terminals.

Step 5: Ensure all productions are in the form A → BC (binary productions).

Applying these steps to the given grammar:

Step 1: Eliminate ε-productions

The given grammar doesn't have any ε-productions.

Step 2: Eliminate unit productions

The given grammar doesn't have any unit productions.

Step 3: Convert long productions

S → SS (Remains the same)

S → AB

A → aAAa

B → bBb

B → bb

C → CC

C → a

D → aC

D → bb

Step 4: Convert terminals

No changes are needed in this step as all terminals are already in the grammar.

Step 5: Ensure binary productions

The given grammar already consists of binary productions.

The converted grammar in Chomsky Normal Form (CNF) is:

S → SS | AB

A → aAAa

B → bBb | bb

C → CC | a

D → aC | bb

Note: The original grammar didn't include the production rules for the non-terminals 'S', 'C', and 'D'. I assumed the missing production rules based on the provided information.

Structured programming encourages dividing an application program into a hierarchy of modules or autonomous elements, which may, in turn, contain other such elements. Within each element, code may be further structured using blocks of related logic designed to improve readability and maintainability.

Explanation:

Note that  activities B and D have been made possible because of improvements in computer networks.

A computer network is a collection of computers that share resources that are located on or provided by network nodes. To interact with one another, computers employ standard communication protocols across digital links.

In computer networking, nodes and connections are the fundamental building components. A network node can be either data communication equipment (DCE) like a modem, hub, or switch or data terminal equipment (DTE) like two or more computers and printers.

A link is the transmission medium that connects two nodes. Physical links, such as cable lines or optical fibers, or open space utilized by wireless networks, are examples of links.

Answer:

147 Kibibits or 18.4 KiB

Explanation:

Given that KiB = kibibyte = 2^10 bytes

Hence 16 KiB is 16384 (2^14) bytes = 4096 (2^12) words.

Therefore, with a block size of 4 words (2^2), we have 1024 (2^10) blocks

Given 32 bits address

We have 4 x 32 = 128 bits of data

The total bits is calculated as (number of blocks) * (data (32 * 4) + tag and validation bits)

Where index part = 10 bits, Offset = 2 bits

2^10 * (4 x 32 + (32–10–2 - 2) + 1)

=> 2^10 * 147 = 147 kibibits

=> 18.4 KiB

Answer: NAT

Which of the following allows hundreds of computers all to have their outbound traffic translated to a single IP? One-to-many NAT allows multiple devices on a private network to share a single public IP address.

The following that allows for  hundreds of computers all to have their outbound traffic translated to a single IP is the One-to-many NAT.     Option C

One-to-many NAT allows hundreds of computers to have their outbound traffic translated to a single IP this is done by designating each computer to  a unique port number, that is used to identify the specific device within the the network address transition NAT, where all private network gain access to public network     .

The NAT device serves as translator, keeping track of the original source IP and port number in the translation table, translates the source IP address and port number of each outgoing packet to the single public IP address,  This allows for a possible multiple devices to share a single IP address for outbound connections.

0.0051825 ms

Explanation:

From the given information:

The clock time is = \(\dfrac{1}{clok \ rate}\)

\(=\dfrac{1}{6} Ghz\)

\(=\dfrac{1}{6}\times 10^9\)

To milliseconds, we have;

= 0.000000625 ms

However, the execution time is the sum total of all instruction types multiplied by the ratio of cycles taken per instruction and cycle time.

Mathematically;

Execution time is: \(\Bigg[Sum \ of \ all \Big(instruction \ type \times \dfrac{cycles taken }{instruction} \Big) \Bigg] \times cycle \ time\)

Recall that:

the cycles taken according to the ALU = 400 × 7 =2800

cycles required according to the memory instructions = 300 × 12 = 3600

cycles for branching = 90×21 = 1890

THUS;

Total cycles = 2800 + 3600 + 1890

= 8290 cycles

Finally, execution time = 8290 cycles × 0.000000625 ms

= 0.0051825 ms

Answer:

c. $620

Explanation:

To find the cost of the security deposit, we need to subtract the amount paid towards the first and last month's rent from the total move-in cost.

Each friend paid $640 towards the total move-in cost, which includes the first and last month's rent and the security deposit. Since they split the cost evenly, the total move-in cost is 3 times $640, which is $1920.

The monthly rent is $650 per month, so the first and last month's rent combined is 2 times $650, which is $1300.

To find the security deposit, we subtract the first and last month's rent from the total move-in cost:

Security deposit = Total move-in cost - First and last month's rent

Security deposit = $1920 - $1300

Security deposit = $620

Therefore, the security deposit was $620.

Option c. $620 is the correct answer.

Answer:

1. Arrows

2. Outputs

Explanation:

The matrix A=[-4 2 1;2 -4 1;1 2 -4] can be created by using the following code in Matlab/Octave:

A = -4*eye(3) + 2*(eye(3,3) - eye(3)) + (eye(3,3) - 2*eye(3))

Here, eye(3) creates an identity matrix of size 3x3 with ones on the diagonal and zeros elsewhere.

eye(3,3) - eye(3) creates a matrix of size 3x3 with ones on the off-diagonal and zeros on the diagonal.

eye(3,3) - 2*eye(3) creates a matrix of size 3x3 with -1 on the off-diagonal and zeros on the diagonal.

The code above uses the properties of the identity matrix and the properties of matrix addition and scalar multiplication to create the desired matrix A.

You can also create the matrix A by using following code:

A = [-4 2 1; 2 -4 1; 1 2 -4]

It is not necessary to create the matrix A using only ones and zeroes but this is one of the way to create this matrix.
