What is optical memory?
Optical memory is an early form of computer memory. It involves the use of an optical system for the writing and reading of data to and from a computer's main memory.
What are the main categories of optical laser disks?
Main categories of optical laser disks are CD-ROM,WORM Disk/CD-Record able(CD-R) Disks,CD Read/Write(CD-RW) Disk,Digital Video(or Versatile)Disk(DVD).
What is auxiliary memory give an example of auxiliary memory?
The major difference between main memory and auxiliary memory is that main memory is directly accessed by CPU but the auxiliary memory is not accessed by the CPU directly.For this the data is first transferred to main memory from auxiliary memory and then from main memory the data is transferred to the CPU for further processing. Some examples of auxiliary memory would be disks, external hard drives, USB drives, etc.
What component has the fastest speed on computer?
Register. The memory hierarchy in the decreasing order of speeds: 1. Register 2. Cache 3. Main memory 4. Disks 5. Auxiliary memory
What is the main memory of the computer?
# Main memory is the short term memory of a computer. It retains data only for the period that a program is running, and that's it.
Distinguish between primary memory and auxiliary memory?
the main memory is the central storage unit of the computer system. it is relatively large and fast memory used 2 store the programs and data during the computer operation.main memory communicates directly with the CPU. main memory includes RAM and ROMs. devices that provide backup storage are known as auxillary memory. auxillary memory are relatively slow in comparision to the main memory. auxillary memory includes flash memory,magntic disks and floppys. main memory is located inside the CPU but auxillary memory is located out the CPU. the main memory is the central storage unit of the computer system. it is relatively large and fast memory used 2 store the programs and data during the computer operation.main memory communicates directly with the CPU. main memory includes RAM and ROMs. devices that provide backup storage are known as auxillary memory. auxillary memory are relatively slow in comparision to the main memory. auxillary memory includes flash memory,magntic disks and floppys. main memory is located inside the CPU but auxillary memory is located out the CPU.
What devices held information before memory sticks?
Floppy disks were often used before USB or memory cards existed. It was the main form of saving data at that time.
What is memory corruption in C?
Memory corruption in C refers to situations where a program unintentionally alters the contents of memory locations that it is not supposed to access or modify. This can lead to unexpected and potentially dangerous behavior, such as crashes, data corruption, or security vulnerabilities. Memory corruption in C is often a result of issues like buffer overflows, uninitialized variables, or improperly managed memory allocations.
What is Dells best HPs best and sonys best laptop Price is not a factor and the laptop has to have a internal disc optical drive?
As different people have different ideas on what is best you may be better off to go to the websites of each of the companies you listed andlooking for yourself. Internal optical disk drive are now essential these days as the Digital Versatile Disks or optical disks are the main way of installing programs, including operating systems, onto computers
Difference between primary and secondary memory?
Primary memory refers to the main memory that is directly accessible by the CPU, such as RAM, used for storing data and instructions currently in use by the computer. Secondary memory, like hard drives or SSDs, is used for long-term storage of data and programs even when the system is powered off. Primary memory is faster but has limited capacity, while secondary memory is slower but has greater storage capacity.
Draw the block diagram of ram and explain its operation?
Memory is technically any form of electronic storage. Personal computer system have a hierarchical memory structure consisting of auxiliary memory (disks), main memory (DRAM) and cache memory (SRAM). A design objective of computer system architects is to have the memory hierarchy work as through it were entirely comprised of the fastest memory type in the system.
What kind of software scans a computer's hard disk floppy disks and main memory to detect viruses and sometimes destroy them?
Antivirus programs, ex. Norton, Symantec, BitDefender, Avast.
