In the internal memory of a computer, the role of a ROM is:

ROMs are read-only memory.

read-only memory), which can only read out the data stored in advance. It is characterized by the fact that once the information is stored, it cannot be changed or deleted. It is usually used in electronic or computer systems that do not require frequent data changes.

and the data will not disappear due to power off.

The data stored in the ROM is generally written in advance before being loaded into the whole machine, and can only be read out during the working process of the whole machine, unlike random memory.

That makes it quick and easy to rewrite. The data stored in the ROM is stable, and the data stored in the ROM will not change after the power is off; Its structure is relatively simple and easy to read, so it is often used to store various fixed programs and data.

The role of ROM is to store data, and hard disk is a type of ROM.

The peculiarity of ROMs is that the stored data is not lost after a power failure, but its data transfer speed is slower than that of RAM.

There are two common types of ROMs, read-only ROMs and rewritable ROMs.

The most common read-only ROMs are CD-ROMs (CD-ROM, ***-ROM), and in the early days of computers, there would be read-only BIOS EPROM

Rewritable ROMs include a wide range of ROMs, including hard disks, CD-ROMs that can be rewritable multiple times, USB disks, and floppy disks that have been eliminated.

ROM: Only random messages can be read out.

The data in the selection cannot be changed. The last D is the function of RAM, which provides the space to run, that is, the user's applications and data.

This is a fill-in-the-blank question, it should be written, hard disk, CD.

Summary. Hello and thank you for your question. Memory capacity = number of words * number of digits.

The 10-digit address code and the number of words is 2 10 = 1024 capacity = 1024 * 8 = 8192 bits.

Memory capacity is expressed as the product of the number of addresses in the memory address register mar and the number of stored word digits. Every 8 bits make up a byte. An English letter occupies one byte, that is, 8 bits, and a Chinese character occupies two bytes.

In general, bits are abbreviated as lowercase letters "b", and bytes are abbreviated as uppercase letters "b".

The storage capacity is 8k 8-bit rom memory, how many bits is the storage capacity Hello, thank you for your question. Memory capacity = number of words * number of digits. The 10-digit address code and the number of words is 2 10 = 1024 capacity = 1024 * 8 = 8192 bits.

Thank you for your question and have a great day!!

The main differences between Read-Only Memory (ROM) and Random Access Memory (RAM) are:

1. Different meanings 1. ROM is the abbreviation of read-only memory, which is a kind of solid-state semiconductor memory that can only read out the data stored in advance. 2. RAM is random access memory, also known as main memory, which is the internal memory that directly exchanges data with the CPU. Second, the role is different: 1, the main role of the read-only memory is to complete the power-on self-test of the system, the initialization of each functional module in the system, the basic input and output drivers of the system and the boot operating system.

2. RAM is the internal memory that directly exchanges data with the CPU. It can be read and written at any time, and it is fast, often as a temporary data storage medium for the operating system or other running programs. 3. The characteristics of the two are different: 1. The ROM memory can only be read, it only allows a chance to write once it is produced, and the data cannot be changed once it is written.

Another feature of the memory is that the data inside is not lost after the memory is powered off. 2. RAM can be read and written at any time, and the data saved on it will automatically disappear after power failure.

Computer memory, also known as memory, is an electronic device made of semiconductor technology to store data. The data of an electronic circuit is stored in a binary format, and each memory cell of the memory is called a memory element.

For a 32-bit operating system, you can use up to 232 addresses, which is 4 gib. Physical address expansion allows processors to access more than 4giB of memory on 32-bit operating systems, and the development of 64-bit processors is the fundamental solution, but there will be compatibility issues with operating systems, drivers, and applications.

Answer] :d Tanhui shirt analysis] The content in the ROM can only be read and not written, and its content is written by the chip manufacturer during the production process. Since the ROM is powered by batteries, even if the computer is turned off, the locust information in the ROM will not be lost, so the ROM in the computing chamber machine is called read-only memory.
