Which Parts Of A Computer Can Store Program Code
Introduction
Most of the programs (including the operating system itself) are stored in machine language format on a hard disk or other storage device, or in thepermanent EPROM memory of the computer. When it is required, the programcode is loaded into memory and then it can be executed. Where is software stored when the computer is off?
Which parts of the computer take user input? microphone, mouse, and keyboard Which parts of the computer give information to the user? peripheral devices (output), display screen, speakers, and printers

Go far enough back, and youll find compilers that store working data (possibly even portions of the symbol table) on disk, drum, or other media outside the main RAM. And on virtual-memory systems, RAM may get swapped out to disk anyway if theres enough memory pressure.
Which parts of the computer give information to the user?
Which parts of the computer take user input? microphone, mouse, and keyboard Which parts of the computer give information to the user? peripheral devices (output), display screen, speakers, and printers
Examples of input devices include keyboards, mice, scanners, digital cameras and joysticks. In computing, an input device is a peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system such as a computer or other information appliance. The three parts of a computer responsible for output are the data writing output, such as a CD drive or USB drive. The second thing is the display, or screen.

Where is the operating system stored in memory?
The Operating System is stored on the Hard Disk, but on boot, the BIOS will start the Operating System, which is loaded into RAM, and from that point on, the OS is accessed while it is located in your RAM. Where is Windows stored on a computer?
So in computers, Operating System is installed and stored on the hard disk. As hard disk is a nonvolatile memory, OS does not lose on the turn off. But as the data access from the hard disk is very, slow just after the computer is started OS is copied into RAM from the hard disk.
The main memory should oblige both the operating system and the different client processes. Therefore, the allocation of memory becomes an important task in the operating system. The memory is usually divided into two partitions: one for the resident operating system and one for the user processes.
The operating system can be stored in firmware as well as disk. Which approach is best? Theres no one right answer, as it depends on whats important in your design.
Where is the data stored in a compiler?
Heres my first attempt: The compiler (not the machine) chooses where to store the variables in the process address space automatically. Using C, we cannot tell the machine where to store variables.
The compiler decides where to place the six variable within this stack frame, maybe at 8 bytes from the frame start and remembers that relative position. So, the instructions that the compiler produces for the function, are: advance the stack pointer by enough bytes for all the local variables of the function.
Data types in C decide what can be stored in a variable, and memory is allocated accordingly. For example, a variable can store a simple numeric digit in an int type variable, a letter of the alphabet in a char type variable, or a decimal number in a float type variable.
How data is stored in computer memory. As we all know, computer is an electronic device where data is stored in the form of electronic signals. Bit is the basic unit of memory. At a time, it can be either on or off. Generally, bits are represented using electrical voltage. Voltage presense indicates that the bit is in ON state.
Where is the operating system stored on a computer?

But as the data access from the hard disk is very, slow just after the computer is started OS is copied into RAM from the hard disk. Where are the operating system files stored in a computer?
Most system files of a Windows operating system are stored in the folder C:Windows, especially in such subfolders as /System32 and /SysWOW64. You will also find system files in a users folder (for example, AppData) and application folders (for example, Program Data or Program Files).
When any user is working on a computer, the operating system is the software thats controlling everything thats happening, in real-time. In order to understand where the operating system is stored on the device, you need to understand the difference between the different kinds of memory, RAM vs hard disk.

What happens to the operating system when the computer is off?
The first thing a computer has to do when it is turned on is to start up a special program called an operating system. The operating systems job is to help other computer programs to work by handling the messy details of controlling the computers hardware. The boot process is something that happens every time you turn your computer on.
One way or the other, at the end of the process, on modern hardware, the operating system turns off the power. What that means depends, of course, on the hardware.
The operating systems job is to help other computer programs work by handling the messy details of controlling the computers hardware. The boot process is something that happens every time you turn your computer on. You dont really see it, because it happens so fast.
Once all processes have stopped and the file systems are unloaded, the kernel sends an ACPI signal to the BIOS that turns the power supply off. Why do most operating systems take so long to shutdown? I mean hey, they dont need to initialize something or even load resources into memory.
How is memory allocated in an operating system?
Memory allocation is an action of assigning the physical or the virtual memory address space to a process (its instructions and data). The two fundamental methods of memory allocation are static and dynamic memory allocation.
Memory management is a method in the operating system to manage operations between main memory and disk during process execution. The main aim of memory management is to achieve efficient utilization of memory. Allocate and de-allocate memory before and after process execution. To keep track of used memory space by processes.
Here, the memory is allocated to the entities of the program when they are to be used for the first time while the program is running. The actual size, of the data required, is known at the run time so, it allocates the exact memory space to the program thereby, reducing the memory wastage.
In this tutorial, we will cover the concept of Contiguous Memory Allocation in an Operating System. In the Contiguous Memory Allocation, each process is contained in a single contiguous section of memory.
Should the operating system be stored in firmware or disk?
2.10 Why do some systems store the operating system in firmware, while others store it on disk? Answer: For certain devices, such as handheld PDAs and cellular telephones, a disk with a file system may not be available for the device. In this situation, the operating system must be stored in firmware.
Answer: For certain devices, such as handheld PDAs and cellular telephones, a disk with a file system may be not be available for the device. In this situation, the operating system must be stored in firmware. 2.11 How could a system be designed to allow a choice of operating systems from which to boot?
In this situation, the operating system must be stored in firmware. Answer: For certain devices, such as handheld PDAs and cellular telephones, a disk with a file system may not be available for the device. In this situation, the operating system must be stored in firmware .
So in computers, Operating System is installed and stored on the hard disk. As hard disk is a nonvolatile memory, OS does not lose on the turn off. But as the data access from the hard disk is very, slow just after the computer is started OS is copied into RAM from the hard disk.
Do computers store data on disk or on Ram?
The cost: Memory is much more expensive than storage. One GB of RAM costs about $8, while 1 GB of hard drive store space costs about 10 cents. Thats the primary reason why the memory has less space than the storage. Speed: RAM runs much faster than storage devices. Thats why a computer need both memory and storage devices for working.
If you need to keep these data such as words and photos, you have to save them in a long-term storage device, like a hard drive. Data in RAM comes from storage devices. When you are trying to access to a file, it will be copied from storage devices and then you can look through and edit itin the memory.
Data in RAM comes from storage devices. When you are trying to access to a file, it will be copied from storage devices and then you can look through and edit itin the memory. If you dont save it again, the changes you just made will be lost when you shut down the computer. It can be read and written anytime with a high speed.
There are TWO places in your computer that can be referred to as memory; the Hard Drive and your RAM. These serve completely different purposes. Hard drives (most typically your C drive) are responsible for storage¦ mostly.
Which of the following is an example of input device?
An input device is a piece of computer hardware used to provide data and control signals to an information processing system such as a computer or other information appliance. . Joystick. Keyboard. Mouse. To scan . Digital camera Nice work! You just studied 15 terms!
Output devices transform the output from the computer into a form understandable by the users. Through this article Input and Output Devices, we shall review the various input and output devices which can be attached to a computer, along with their functions.
In the architecture of a computer one can see that the components used in the computer are Input devices , Output devices, a CPU, and Memory units. In other articles, we have discussed Memory units and Output devices for a computer. Here we are going to discuss 10 examples of mostly used input devices in the computer with images.
The main functioning of a computer system is based on the combined usage of both input and output devices. Utilizing an input device, a user can give directions to the computer to run and the device reverts to the users action through an output device. Lets first understand what is an input unit and output unit.
What three parts of the computer give output?
The three parts of a computer that receive input devices are the mouse, the keyboard and a microphone are all input devices. The parts of a computer that are output devices would be printer, monitor and modem. Which three parts of the computer have output? serial, parallel and USB ports are output.
Output devices examples can be defined as when the computer receives various types of data and instructions through input devices like a keyboard (by typing) and mouse (by clicking), etc. and processes it and gives results through the output devices like Monitor and printer, etc .
The computer transmits the image data to the printer, which then physically recreates the image, typically on paper. As Printers can only print the already processed data, these devices can only be treated as output devices. It is classified into multiple types, depending on the speed, printing patterns, type of ink used, etc. 3.
Yes, TV is designed to display useful and entertaining shows. It displays all the data as Soft Copy on its screen. A TV is also known by the display, video display, video display unit, video display terminal, or video screen. Input Devices Of Computers, Types, and Examples. Both Input and Output, (I/O Devices) of Computer.
What are the 5 parts of a computer?
Every computer comprises 5 basic parts, namely, a motherboard, a central processing unit, a graphics processing unit, a random access memory, and a hard disk or solid-state drive. Be it a high-end gaming computer system or be it a basic desktop system for kids, every computer consists of the afore-mentioned 5 parts.
No matter a persons age, its important to understand the basic parts of a computer. Learning the names and functions of these seven main computer components will help new and young technology users to communicate effectively with others about the tasks they are using a computer to perform.
In laptops it isnt such a big box and also includes the keyboard and screen . These cases come in different sizes and shapes and these parameters have nothing to do with the performance of your computer. There are also computers which dont have these and all the components are built into the monitor (say, All-In-One Desktops). 2.)
One of the basic parts of computer is constituted by its storage components. The solid-state drive and the hard disk drive are the key storage components of a computer. The hard disk drive of a computer system stores data permanently. Therefore, even if you turn off the computer, the data stored in the hard disk drive will be saved.
How does the compiler decide where to store variables?
At some point, for local variables, the compiler assigns either a stack location or a CPU register (it can be more complex in that the variable can actually have multiple locations, such as a stack location for some parts of the generated code and a CPU register for other sections).
The compiler decides where to place the six variable within this stack frame, maybe at 8 bytes from the frame start and remembers that relative position. So, the instructions that the compiler produces for the function, are: advance the stack pointer by enough bytes for all the local variables of the function.
Using C, we cannot tell the machine where to store variables. But that automatically is somewhat anticlimactic and begs the question… and Ive realized I dont even know if its the compiler or the runtime or the OS or who does the assignment.
Typically local variables are put on the stack. This means that the compiler assigns an offset to the stack pointer which can be different depending on the invocation of the current function. Ie the compiler assumes that memory locations like Stack-Pointer+4, Stack-Pointer+8, etc. are accessible and usable by the program.
What are the instructions that the compiler produces for a function?
Compilers are an essential part of a computer programmers toolkit. A compiler turns a plain text file containing code into a program that can be run. A common misconception is that computers understand code. This is not true. Computers only understand machine code, that is, code that is assembled for the architecture of the computers processor.
Compilers typically generate machine code into object files that are then linked together by a linker program.
This phase removes unnecessary code line and arranges the sequence of statements to speed up the execution of the program without wasting resources. The main goal of this phase is to improve on the intermediate code to generate a code that runs faster and occupies less space. Code generation is the last and final phase of a compiler.
Some programming languages are written so a compiler can read the source code only once and generate the machine code. Pascal is one such language. Many compilers require at least two passes.
Conclusion
Data types in C decide what can be stored in a variable, and memory is allocated accordingly. For example, a variable can store a simple numeric digit in an int type variable, a letter of the alphabet in a char type variable, or a decimal number in a float type variable.
Data types can be int, float, char, double , long int, etc. variable_name: Indicates the name of the variable. It can be anything other than the keyword. For example, 1, int is a data type, and a is a variable name. In the second example, we have declared three variables, a, b, and c.
Its typically used for saving data. Variables are described through name, type, location and data allocated to them. Data types in C decide what can be stored in a variable, and memory is allocated accordingly.
There are set of rules to be followed while declaring variables and data types in C Programming: The 1st letter should be alphabet. Variables can be combination of alphabets and digits. Underscore (_) is the only special character allowed. Variables can be written in both Uppercase and Lowercase or combination of both. Variables are Case Sensitive.
