5 reasons why an Operating Systems is referred as a resource allocator?
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.
Difference between xerophytic plants and coniferous plant
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.
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.
The history of computer starts with the simple tool all we have heard about, "The Abacus".
Let us learn how and when did it lead to the invention of Computers.
The initial computers did not have any monitor and memory. The abacus - adding machine is a wooden rack holding horizontal wires with beads strung on them. It was invented in Babylon around 2000 years ago.
In 1822, Charles Babbage, a professor of mathematics, designed an automatic mechanical machine called difference engine, which is a type of counting machine. He also introduced another machine called Analytical Engine which could store information on punched cards. Babbage invented all necessary parts that modern computer use, but it wasn't until 1940 that modern computers were introduced. Charles Babbage is known as the father of the computer.
Generation of computers:
Since their invention, Computers have evolved and advanced quickly. Commonly we can group the developments in computers into five generations. Change in technology is referred to be as 'Generation'. All the generations are explained in the following points.
First Generation (1940-1956):
First-generation computers, such as UNIVAC - I (Universal Automatic Computer - I) and ENIAC (Electronic Numerical Integrator Analyzer and Computer), were huge.
They took huge space because they used vacuum tubes for circuits and magnetic drums for memory storage.
They consumed a large amount of electricity and generated a lot of heat.
They were very expensive.
They used machine language.
Second Generation (1956-1963):
Second-generation computers used two types of devices namely transistors and magnetic core.
Transistors replaced vacuum tubes in circuits, and the magnetic core replaced magnetic drum for memory storage.
Second-generation computers outwitted first-generation computers due to transistors, making the computers smaller in size, faster (microseconds), cheaper, energy-efficient and more reliable.
In second-generation computers, transistors replaced the vacuum tubes but still generated a lot of heat that caused damage to the computers but comparatively lesser than the first-generation.
Instead of a Machine language, Assembly language was used.
A translator is used to convert the assembly language into machine language. This translator is called as an assembler.
Examples - IBM - 1920,IBM - 1401, etc.,
Third Generation (1964-1971): IBM - 360
The third-generation computers were the improved version of second-generation computers, where the transistors were replaced by Integrated Circuits (IC).
Integrated circuits were silicon chips where multiple transistors were placed. This reduced the size of the computers massively.
They were cheaper than the previous generation.
This generation of computers used parallel processing to improve processing efficiency.
These computers could calculate the data in nanoseconds.
For Programming, high-level languages were used.
These computers were general-purpose computers and used for commercial purpose also.
Operating system and other application software were introduced and used.
Examples - IBM - 360series, CDC - 1700, etc.,
Fourth Generation (1971-Present):
Fourth-generation computers were introduced after third-generation computers, which generally used microprocessor.
A Microprocessor generally consists of thousands of integrated circuits built on a single chip known as a silicon chip.
Very Large Scale Integration (VLSI) technology used. Billion of circuits per cubic foot.
Computation speed - Picoseconds
Smaller in size, faster and more reliable
They use less electricity and generating less heat.
Examples - Apple, Cray - 1, etc.,
Fifth Generation (Present):
After the invention of fourth-generation computers, the fifth-generation computers were introduced.
The fifth-generation computers or modern-day computers are based on Artificial Intelligence (AI) and are still in their developmental phase. Japan invented the FGCS (Fifth Generation Computer System) in 1982.
This generation computer is based on microelectronic technologies with high computing speeds and parallel processing.
