What are the characteristics of ROM and RAM?
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.
What are the characteristics of RAM?
Features of RAM:
RAM is volatile in nature, which means, the data is lost when the device is switched off. RAM is known as the Primary memory of the computer. RAM is known to be expensive since the memory can be accessed directly. RAM is the fastest memory, therefore, it is an internal memory for the computer.
What are the main functions of ROM?
ROM provides the necessary instructions for communication between various hardware components. As mentioned before, it is essential for the storage and operation of the BIOS, but it can also be used for basic data management, to hold software for basic processes of utilities and to read and write to peripheral devices.
What are the 4 types of ROM?
ROM is further classified into four types- MROM, PROM, EPROM, and EEPROM.
What are the characteristics of a virtual memory?
What is Virtual Memory?
| Virtual Memory | Physical Memory |
|---|---|
| Uses paging | Uses a the swapping technique |
| In comparison between the two types of memory, virtual memory is slower than physical memory | Physical memory is faster than virtual memory |
| Limited by the size of the hard disk | Limited to the size of the RAM chip |
What are the characteristics of cache memory?
Cache memory is an extremely fast memory type that acts as a buffer between RAM and the CPU. It holds frequently requested data and instructions so that they are immediately available to the CPU when needed. Cache memory is used to reduce the average time to access data from the Main memory.
What are the advantages and disadvantages of ROM?
ROM is inexpensive, can keep data on a permanent basis, but it has its own set of drawbacks such as hard to change the data for a fixed period of time. RAM is costly but data can be altered several times on it at the same time.
