Note:
Each token/comment starts with a unique type of character (letter, digit, . . ., etc). If a character read from the input stream cannot be the first character of any token/comment, it is declared an invalid character.
1. Define function tokenType lexical_error(void) that reads an (invalid) character, copies it into the buffer and returns the code for invalid characters.
2. Write the function tokenType scanner (void) (with a local variable int character to hold the next character read from the input stream) as follows:
1. call the function skipSpaces( ) to skip over spaces.
2. For the first non white space character, it does the following:
a) If it is EOF (end-of-file character), it returns EOF to the caller.
b) Otherwise it does the following:
- use the putback(char ch) function to put that character back into the input stream.
- test to find out the token/comment (identifier, comment, +, real constant, ... etc) that starts with this character: (one character look ahead)
- call the language recognition device that corresponds to that token/comment or the function lexical_error( ) if there is none.
- returns to the calling function the code returned by the function called above.
Note
1. If you have included the division operator ( / ) as one of the operators, then when function scanner reads the division operator, it needs to peek the next character in the input stream in order to decide whether to call function get_comment( ) of function get_div( ).
2. Functions getId(),getComment(),getReal(),getStrings(),getAssign(),and getPlus()are provided below. You will need functions to recognize the other punctuators and operators of the programming language.
3. Write function main that does the following:
1. Write the heading for the output table. For example:
TOKENS/TYPES WORDS/LEXEMS
1. Then in a loop that terminates when the value returned by function scanner( ) is EOF, it does the following:
- call function void clear_buf(void)) to clear the buffer.
- call function tokenType scanner(void) ).
- call function void display_token(tokenType code) with the token code returned by scanner function to display the appropriate message, and prints the contents of the buffer.
End-Of-File Character
1. The end-of-file character (-1) is named EOF (which are macro-constants defined in the header file stdio.h). You must therefore include this header file in any source module in which this macro constant is used. You may also use -1 instead of EOF.
2. When you type the input data in a UNIX system, you enter the end-of-file character by pressing the key sequence -d . In the Microsoft Windows systems, you have to press the key sequence -z.
INPUT: The input of your program must be any sequence of lexemes of your language: For example:
num1:= 12.5; "It is nice outside" /* compute area */ sum + { * ) sum := num1?
OUTPUT: The output of your program should look like the following:
TOKENS/TYPES WORDS/LEXEMS
------------------------ -------------------------
Identifier num1
Assignment :=
Real constant 12.5
Semi colon ;
String constant "It is nice outside"
Comment /* compute the area */
Identifier sum
Plus +
Left brace {
Multiplication operator *
Left-parenthesis (
Identifier sum
Assignment :=
Identifier num1
Invalid Character ?
You may use input/output redirection to run your program. To do this, you must first compile and link your program modules to produce an executable file; then run your program on the UNIX system as follows:
programfile < datafile > outputfil

Full-duplex communication allows for simultaneous transmission and reception on the medium by both devices. The Data Link layer implies that the media is constantly accessible to both nodes for transmission.

Half-duplex communication happens when both devices can both transmit and receive on the medium but cannot do so simultaneously. Media arbitration is not necessary in full-duplex communication because both devices can send and receive data simultaneously through the medium.

Wireless communication is often referred to as Unguided Media or Unbounded transmission media. In this mode, no physical media required for the transmission of electromagnetic signals.

Answer:

The carrying capacity of an ecosystem, for example the Earth system, is the ability of an ecosystem to provide biological species for their existence; that is, the living environment is able to provide them with a habitat, sufficient food, water and other necessities for a longer period of time.

When the populations of different species living in an ecosystem increase, the pressure on the environment increases, partly due to intensive use. The population size decreases again when the population exceeds the carrying capacity, so that a natural equilibrium is maintained. This is due to a number of factors, depending on the species involved. Examples are insufficient space, sunlight and food.

Thus, given the current conditions of pollution, extinction of species and other environmental damage caused by humans on Earth, it can be said that we are about to exceed the limit of carrying capacity of the Earth, which would imply that this, through different natural forces, would seek to stabilize said overpopulation to return the environmental environment to a state of equilibrium.

Address buses are made up of a collection of wires connecting the CPU with main memory that is used to identify particular locations (addresses) in main memory. The width of the address bus (that is, the number of wires) determines how many unique memory locations can be addressed.

Explanation:

Address buses are made up of a collection of wires connecting the CPU with main memory that is used to identify particular locations (addresses) in main memory.

What is CPU?

The electronic equipment that carries out the instructions included in a computer program is known as a central processing unit (CPU), sometimes known as a central processor, main processor, or simply processor.

The CPU executes fundamental mathematical, logical, controlling, and input/output (I/O) activities as directed by the program's instructions. In contrast, specialized processors like graphics processing units and external components like main memory and I/O circuitry (GPUs).

Although CPUs' shape, design, and implementation have evolved throughout time, their basic function has remained mostly same. The arithmetic-logic unit (ALU), which performs arithmetic and logic operations, processor registers.

Therefore, Address buses are made up of a collection of wires connecting the CPU with main memory that is used to identify particular locations (addresses) in main memory.

A switch uses Layer 2 addresses (MAC addresses) and Layer 3 addresses (IP addresses) to make forwarding decisions.

Switches operate at the data link layer (Layer 2) of the OSI model and are responsible for forwarding data frames within a local area network (LAN). They use various criteria to make forwarding decisions and determine the destination of a frame.

Layer 2 Addresses (MAC addresses): Switches primarily use MAC addresses, which are unique identifiers assigned to network interface cards (NICs), to make forwarding decisions. Each frame contains source and destination MAC addresses, and the switch maintains a MAC address table (also known as a forwarding table or CAM table) that maps MAC addresses to switch ports. By examining the destination MAC address of a frame, the switch can determine the outgoing port to forward the frame to.

Layer 3 Addresses (IP addresses): In addition to MAC addresses, some switches also support Layer 3 forwarding decisions using IP addresses. These switches are known as Layer 3 switches or multilayer switches. They can perform routing functions by examining the destination IP address in the packet header and making forwarding decisions based on IP routing tables. Layer 3 switches combine the features of switches and routers, allowing for more advanced networking capabilities within a single device.

By considering both Layer 2 addresses (MAC addresses) and, in the case of Layer 3 switches, Layer 3 addresses (IP addresses), switches can efficiently forward frames within a LAN and, in the case of Layer 3 switches, route packets between different networks.

When the twelve entries in the matrix are stored in row major form in locations 7,609 to 7,620 in a computer's memory, it means that the entries in the first row are stored first, followed by the entries in the second row, and lastly the entries in the third row

. So, we have to figure out which location a21 will be stored in. To do this, we must first understand that a21 refers to the entry in the second row and first column of the matrix. Since we know that the first row is stored first, we can deduce that the first entry in the second row will come after the last entry in the first row. The number of entries in the first row is 4 because there are 12 entries in the matrix and 12/3=4 rows. The first row will be stored in locations 7,609 to 7,612 since there are 4 entries in the first row. Since the entries in the first row are stored first, the entry a21 will be stored in location 7,610.

Pyramid of energy is a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.

The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).

Organisms in a food web are related through producer/consumer, predator/prey, and parasite/host relationships. Because of these relationships, one population affects others through direct and indirect interactions. A direct interaction refers to the linear relationship between two organisms such as predator feeding on a prey (a lion eating a deer) while an indirect interaction is a type of relationship that occurs or is mediated through a third.
