Plants are able to make their own food through photosynthesis, thus are called Autotrophs. As animals are unable to synthesise their own food and organic material, they depend on plants and attain plant's complex organic material by consuming the plant. As a result animals eating plants are herbivores. The animals that cannot directly consume plants, depend on these herbivores for the complex organic material and energy, and are called Carnivores.

Carl Linnaeus was a swedish botanist/zoologist and physician. He is also known as the father of modern taxonomy.

Animals that can breathe on both (land & water) are called Amphibians.

For example:- frogs, salamanders & toads etc.

First thing to understand is the Resource Pool. As the name suggests, it can be visualized as a group of available CPU and memory resources, that can be shared among different processes. Through a resource pool, such resources can be effectively managed by maintaining for what the particular resources is reserved for, any limit details, and which other processes share the resource.

Now the Operating System is referred to as a 'Resource Allocator', as it allocates resources from the Resource Pool to various processes/programs as requested and/or required before the initiation of the process.

When a process/program is initiated, OS checks the Resource Pool to see if the required resources (CPU, memory) are available in the pool. If the resource(s) is/are free, it allocates them to the requesting program and updates the Resource Pool with the allocation status.

As and when a process completes, the OS de-allocates the resources assigned to it and add it back to the Resource Pool and re-assigns to any other process as per the need.

Please do let me know if this was helpful.

Let's understand the pros & cons of C programming in a simple way.

Pros:-

1) Portable language:- Since it is based on ASCII characters, it is compatible with a wide range of operating systems and platforms, for example, Windows, Linux, Mac OS X, Android, and iOS.

2) Simple 2 write

3) Simple 2 debug

4) Dynamic memory allocation - It implies that we have complete freedom to allocate memory at run time.

Cons:-

1) It doesn't support " Inheritance ".

2) Concept of OOPs - Like point no. 1, it doesn't support the concept of OOPs like Polymorphism, Encapsulation, Abstraction, and Data Hiding as well.

3) Run time checking - unlike other programming languages, it shows errors after the compilation. Which is not at all good for large codes of programs.

We hope it will clear your query.

Thanks

Hydrophytes - They are plants which are adapted to live in aquatic environments. They can  be fully or partially submerged or can be floating in water. They have special adaptations which help in their survival in water. For example, they have spongy tissue in stems, roots and leaves which creates air spaces and allows exchange of  gases. They also have floating leaves with long dissected petioles to prevent water flooding. Stomata in these plants can be absent or are always open if present. This is because they dont have the requirement to save water. Xylem vessels in these plants are poorly developed. Example:  Hydrilla .

Xerophytes -  They are plants which are adapted to  dry conditions. They have adaptations which help them in preventing water loss and store water. When they store water, such plants are called succulents which is possible due to presence of thick, fleshy stems. They also have waxy coatings on leaves which help them to prevent water loss. Some other adaptations which help them to prevent water loss are dropping of leaves during dry periods, folding or repositioning of leaves to prevent loss of water through excess sunlight exposure, hairy coverings on leaves. Examples - cacti, agave. 

Difference between RAM and ROM:

RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in the computer. 

RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.

RAM (Random Access Memory):

RAM is volatile memory, which means that the information temporarily stored in the module is erased when you restart or shut down your computer. Because the information is stored electrically on transistors, when there is no electric current, the data disappears. Each time you request a file or information, it is retrieved either from the computer's storage disk or the internet. The data is stored in RAM, so each time you switch from one program or page to another, the information is instantly available. When the computer is shut down, the memory is cleared until the process begins again. Volatile memory can be changed, upgraded, or expanded easily by users.

ROM (Read Only Memory):

ROM stands for non-volatile memory in computers., which means the information is permanently stored on the chip. The memory does not depend on an electric current to save data, instead, data is written to individual cells using binary code. Non-volatile memory is used for parts of the computer that do not change, such as the initial boot-up portion of the software, or the firmware instructions that make your printer run. Turning off the computer does not have any effect on ROM. Non-volatile memory cannot be changed by users.

Lan is local area network and Wan is wide area network. When a group of computers are connected in a small area like the building, office it is local area network. When a group of computers are connected over a large area it is Wan.

Third Generation of Computers:

The Third generation computers were faster, smarter, and user friendly compared to previous computers.

These generations of computers were far more advanced than their counterparts as they used and utilized Integrated Circuit IC as their main component.

The IC was advanced technology at that time and therefore increased speed and efficiency, outsmarting the other computers in the market.

Fourth Generation of Computers:

These 4th generations of computers were more reliable and user-friendly than other generations.

They used microprocessors as their main component and installed them in their circuit, which enhanced the overall performance like speed, accuracy, efficiency, and reliability.

The microprocessor increased the computer’s speed, making them multitask, and multiprogramming eventually increased the overall performance.
