Understanding Main Storage
Main storage, often referred to as primary storage or main memory, is a crucial component of a computer system. Here’s a detailed explanation of why it is the correct answer:
1. Definition of Main Storage
- Main storage is where the computer holds data and instructions that are currently in use.
- It enables rapid access to these instructions, facilitating smooth execution by the CPU.
2. Role in Instruction Execution
- The CPU (Central Processing Unit) fetches instructions from main storage to execute them.
- Without main storage, the CPU would lack the necessary information to perform tasks efficiently.
3. Characteristics of Main Storage
- Main storage is typically volatile, meaning it loses its contents when the power is turned off.
- It includes types of memory such as RAM (Random Access Memory), which is essential for active processes.
4. Comparison with Other Storage Types
- Secondary Storage: Unlike main storage, secondary storage (like hard drives) is non-volatile and used for long-term data retention.
- RAM: While RAM is a type of main storage, the term "main storage" encompasses all forms of primary memory used for executing instructions.
5. Conclusion
- In summary, main storage is integral to a computer's functionality, as it serves as the immediate workspace for the CPU during instruction execution.
- Hence, the correct answer to the question is option 'B', which emphasizes the importance of main storage in computer architecture.

- b)Cool Boot
- c)Reboot
- d)Cold Boot

Answer:
To understand the answer to this question, let's break down the options and their meanings:
- Warm Boot: This refers to restarting a computer without turning off the power. It is a software reset and does not erase any data or counters from memory.
- Cool Boot: This term is not commonly used in the context of computer booting. It does not refer to any specific action.
- Reboot: This is a general term that can refer to restarting a computer or any electronic device. It can be either a warm boot or a cold boot, depending on how it is performed.
- Cold Boot: This refers to restarting a computer by turning off the power and then turning it back on. It is a hardware reset and erases any internal data and counters that the operating system and running apps create to keep track of operations from memory (RAM).
- Normal Boot: This term is not specific to any particular type of booting. It can refer to either a warm boot or a cold boot, depending on the context.
Based on the above explanations, the correct answer is option 'D' - Cold Boot. It is the only option that accurately describes the process of turning off the power and erasing internal data and counters from memory.
In a cold boot, the computer goes through the startup process from the beginning, loading the operating system into memory and initializing all necessary components. This process clears any temporary data stored in RAM, ensuring a fresh start for the system.
Performing a cold boot can be useful in situations where the computer is experiencing software issues or has become unresponsive. It allows for a clean restart and can help resolve certain problems.
It's important to note that a cold boot should not be performed without proper consideration, as it can lead to data loss if any unsaved work is present. It is always recommended to save any important data before performing a cold boot.
Overall, a cold boot is a powerful tool for resetting a computer and starting with a clean slate by erasing internal data and counters from memory.

Rahul Mehta answered |
A digital device that processes data is known as data processor.
The processor, more formally known as the central processing unit (CPU), has the electronic circuitry that manipulates input data into the information required by the users. The central processing unit executes computer instructions that are specified in the program.
Some of the most common processing devices in a computer include central processing unit (CPU) and graphics processing unit (GPU).

Nikita Singh answered |
A memory that does not change its contents without external causes is known as static memory.
Static Random-Access Memory (static RAM or SRAM) is a type of semiconductor memory that uses bistable latching circuitry (flip-flop) to store each bit. SRAM exhibits data remanence, but it is still volatile in the conventional sense that data is eventually lost when the memory is not powered.

Non-volatile memory (NVM) or non-volatile storage is a type of computer memory that can retain stored information even after power is removed. In contrast, volatile memory needs constant power in order to retain data. ROM is non-volatile; even after you turn off your computer, the contents of ROM will remain.

Ritika Choudhury answered |
Analog computer works on the supply of Continuous electrical pulses.
An analog computers, works by measuring voltages and currents rather than by the process of counting. An analog computers works on supply of continuous electrical signals and display outputs continuously. Side rule is an example analog device in which numbered as expressed as distances.
A computer that operates with numbers represented by directly measurable quantities (such as voltages or rotations) — compare digital computer, hybrid computer. This contrasts with an analog signal, which represents continuous values; at any given time it represents a real number within a continuous range of values.
