Where is data processed in the computer?
Data is typically processed in the central processing unit (CPU) of the computer. The CPU receives instructions and data from the computer's memory, processes them using arithmetic and logic operations, and then sends the results back to the memory for storage or further processing.
Does data have mass?
No, data does not have mass. Data is information stored electronically and does not have physical weight like a physical object.
What are the components of a variable?
A variable typically consists of a name, a data type, a value, and a memory location where the value is stored. The name is used to reference the variable in the code, the data type defines the type of data the variable can hold, the value is the actual data stored in the variable, and the memory location is where the value is stored in the computer's memory.
Difference between logical database and physical database?
A logical database refers to the conceptual schema or model of data relationships and structures, independent of how data is stored or accessed. On the other hand, a physical database involves the actual implementation of the database on a specific hardware system, detailing how data is stored and accessed. The logical database design focuses on the organization of data, while the physical database design focuses on optimizing performance and storage efficiency.
What is the consequences of changing a field size?
Changing a field size can impact the amount of data that can be stored in that field. Increasing the field size may allow for larger data to be stored without truncation, but it can also increase storage requirements. Decreasing the field size may lead to data loss if existing data exceeds the new size limit.
What is the most suitable device to stored data?
cpu
Is RAM stored directly on the CPU?
No. RAM is a type of memory, not data.
Is RAM stored directly on CPU?
No. RAM is a type of memory, not data.
What is the meaning of buffering an operating system?
Refers to buffering:as reading and writing data from hdd takes long time.so to improve the speed for data processing the data next required by processor is stored is cache memory or CPU register.for e.g. to cut certain line from text file to copy into another file.cut data get stored in to buffer (CPU register) to get back stored into another file.
Does data use the CPU?
The CPU processes data, so data would be using the CPU.
What kind of information is stored inside the computer?
The specific term is "input data". The general term "data" can refer to "input data", "output data", "stored data" inside the computer, the data being processed by the computer's CPU, etc.
Where the constantly needed data is stored?
Constantly needed data is stored in RAM, and depending on the system and the CPU used, it may be stored in cache memory. Cache memory is a special, high-speed type of RAM. It is more expensive and uses more current than DRAM, but it is used where speed is critical. Cache memory is generally inside of the CPU these days.
Do you lose saved programs when changing CPU?
No. Changing a CPU is very similar to changing a ram chip, and neither should cause any loss of data or programs stored on the hard drive.
Which component of the CPU reads data and instructions stored on a floppy disk?
The floppy drive is what actually does the reading. The information is then sent to the central processor unit (CPU) on the motherboard where it is translated. There is no specific part of a CPU dedicated to floppy drive input.
What is the abbreviation for the place in the computer where the programs and data the computer is currently using are temporarily stored?
That place is 'random access memory' - or RAM.
How important is a CPU in terms of memory?
Although memory and CPUs are linked together very closely, a CPU is only important to memory when the memory is active. It is the CPU that writes to and reads from memory (or other devices that are under the control of the CPU). When the memory is idle, its only function is to retain data ready for it to be written over or read. In almost all cases. memory can do this without any intervention by a CPU. In volatile memory, a power supply needs to be provided to retain the data. Non-volatile memory on the other hand will stored data without power. An example of this kind of memory is a USB drive that can be unplugged from a USB port and retain all data without needing either a power supply or a CPU. Memory in fact is rather more important to the CPU than the other way round. The CPU operates as directed by a program that is stored in memory. Without memory, a CPU will not have a program to run so will not be able to fucntion.
Who is the father of CPU?
John von Neumann in the 1940's described the idea of a computer architecture with a CPU (central processing unit) executing computer instructions from the same memory that also stored computer data.
