What is the future of computers?
Future computers promise to be even faster than today’s computers and smaller than a deck of cards. Perhaps they will become the size of coins and offer “smart” or artificial intelligence features like expert intelligence, neural network pattern recognition features, or natural language capabilities.
What are the limitations of computer class 9?
What are the Limitations of a Computer?
- Lack of common-sense.
- Zero IQ.
- No Feeling.
- Computers can’t Decide.
- Computers can’t Express their Ideas.
- Computers can’t Implement.
- Computers can’t Think.
- Depend on the user input.
What are the possible disadvantages of using computers in education?
Financial difficulties may make it difficult for some students to access important coursework, while other students may use computers to plagiarize or cheat.
- Technical Problems.
- Spelling and Handwriting Skills.
- Cheating.
- Financial Problems.
What are the limitations of operating system?
Disadvantages of Operating System :
- It has broadened memory access times, for example, page table query.
- Need improvement with utilizing TLB.
- Required protected page tables.
- Need inner fracture.
- Page Table Length Register (PTLR) needs to bound with virtual memory size.
- It required greater improvement in staggered page tables and variable page sizes.
What are the limitations of internal memory?
Some of the limitations of internal memory are:
- They are not expandable .
- They are fixed .
- Internal memory has the limited capacity of memory .
- It is temporary in nature .
- In EEPROM, writing and reading of the data requires different voltages.
What is difference between RAM and ROM?
RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer. Find out more about RAM.
What is the difference between primary memory and secondary memory?
KEY DIFFERENCE Primary memory data is directly accessed by the processing unit whereas Secondary memory data cannot be accessed directly by the processor. Primary memory is both volatile & nonvolatile whereas Secondary memory is always a non-volatile memory.
What is the primary and secondary memory of computer?
The memory of a computer is classified in the two categories primary and secondary memory. Primary memory is the main memory of the computer where the currently processing data resides. The secondary memory of the computer is auxiliary memory where the data that has to be stored for a long time or permanently, is kept.
What is the main memory of the computer?
Main memory is the primary, internal workspace in the computer, commonly known as RAM (random access memory). Specifications such as 4GB, 8GB, 12GB and 16GB almost always refer to the capacity of RAM. In contrast, disk or solid state storage capacities in a computer are typically 128GB or 256GB and higher.
What is secondary memory of computer?
Secondary memory refers to storage devices, such as hard drives and solid state drives. It may also refer to removable storage media, such as USB flash drives, CDs, and DVDs. That means the computer has roughly 64 times more secondary memory than primary memory.
Why secondary memory is required in a computer?
Secondary storage therefore needed because it is non-volatile, meaning it retains its contents without the need for a power supply. It also has the large storage capacity needed to store the operating system and all the programs and files needed by a modern computer system.
What is software Why secondary memory is important for computer?
It is also known as external memory or auxiliary storage. The secondary memory is accessed indirectly via input/output operations. It is non-volatile, so permanently stores the data even when the computer is turned off or until this data is overwritten or deleted. The CPU can’t directly access the secondary memory.
