What if data is added into random access memory location where data is already present?
When new data is added to a random access memory (RAM) location that already contains data, the existing data is overwritten and lost. RAM is designed for quick read and write access, meaning that each memory address can hold only one value at a time. Thus, writing to that location replaces the previous value without warning, which can lead to data loss if not managed carefully. Proper data management and tracking are essential to avoid unintentional overwrites.

What is the difference between memory address and memory addressability?
A memory address is a specific location in a computer's memory where data is stored. Memory addressability refers to the maximum amount of memory that a computer system can access and use. In other words, memory addressability is the range of memory addresses that a computer can access, while a memory address is a specific location within that range.
Why do we need computer RAM?
Most modern computers use Random Access Memory for their main memory. However you don't need Random Access Memory, Sequential Access Memory is perfectly adequate and has been used in many computers in the past for main memory (it just happens to be much slower to access than Random Access Memory as you need to wait for the location to come around again).
What is the name of the storage location in the computer's memory?
Depending on the architecture of the computer one addressable memory location might be called a word, a character, a parcel, a decimal digit, a byte, etc.
During processing data is stored in which location in computer memory?
Processing of Data is usually done in the Random Access memory
Which location of router memory is cleared when you erase the start up-config?
It is the NVRAM or the Non-Volatile Random Access Memory.
What is an access violation?
An access violation is another name in computing for a segmentation fault, a software error which occurs when a program attempts to access a memory location which it is not permitted to access.
What is 16bite address line in memory location?
A 16-bit address line in a memory location refers to the capability of the address bus to access up to 65,536 unique memory addresses, which is calculated as 2^16. Each address corresponds to a distinct memory location, allowing a system with a 16-bit address line to directly access 64 KB of memory. This limitation is typical in older computer architectures and affects how much RAM can be utilized by the system.
How do you access 1 GB memory with 8085?
You need some kind of memory expander, which maps a frame of addresses to a location in physical memory. Better, use an 8086/8088.
Actual location in main memory?
The actual location in main memory refers to the specific address or location where data or instructions are stored in a computer's RAM (Random Access Memory). This is determined by the memory management unit (MMU), which translates logical addresses used by programs into physical addresses in memory. The organization of this memory is crucial for efficient data retrieval and execution of processes. Accessing the correct location is essential for the system's performance and stability.
What is poiner value in c?
In c a pointer is a variable that points to or references a memory location in which data is stored. Each memory cell in the computer has an address that can be used to access that location so a pointer variable points to a memory location we can access and change the contents of this memory location via the pointer. Pointer declaration A pointer is a variable that contains the memory location of another variable. The syntax is as shown below. You start by specifying the type of data stored in the location identified by the pointer. The asterisk tells the compiler that you are creating a pointer variable. Finally you give the name of the variable. type * variable name Example: int *ptr; float *string;
What is magnetic disk?
RAM:(RANDOM ACCESS MEMORY)RAM is the primary storage device and the data and instructions are stored temporarily in it. It takes the same amount of time to access any location in RAM. CPU can perform two types of operations on Ram, these are:ReadWriteRead operation:during read operation the contents of memory location are copied to a CPU register.Write operation:During write operation the contents of a CPU register are copied to the memory location.
What are the 2 types internal memory?
The RAM (random access memory) and the HDD (hard disk drive).
