1. **ROM(只读存储器)**:存储固定数据,生产时写入,用户只能读取,不可修改。适用长期存储不变的信息。 2. **RAM(随机存取存储器)**:可读写,用于临时存储运行中的数据,断电后数据丢失。 因题干仅提供选项B(ROM),而ROM符合“仅可读取”的特性,故答案为B.ROM。虽然选项中可能缺失其他选项(如A.RAM),但B...
not written to. it is a type of storage that contains data that can’t be changed or modified. rom retains its contents even after the power to the device it's installed in has been turned off. this form of memory is essential to any computer system because it contains the instructions...
(rom), cache memory, virtual memory, and various types of secondary storage devices like hard disk drives (hdds) and solid state drives (ssds). what is random access memory (ram)? ram is a type of volatile memory that stores data and instructions actively used by the computer. ram ...
ROM is an acronym for Read-Only Memory. It refers to a type of computer memory that stores data permanently. A ROM memory chip contains hard-wired instructions that you can't change. It's also nonvolatile, which means it retains its contents even if the device loses power. This characteri...
What is the full form of “ROM”? A. Read Only Memory B. Readable Only Memory C. Record Only Memory D. Reachable Only Memory 相关知识点: 试题来源: 解析 A。“ROM”是“Read Only Memory”的缩写,只读存储器。选项 B、C、D 均不符合“ROM”的正确缩写形式。
Cache memory improves the speed of the CPU, but it is expensive.Type of Cache Memory is divided into different level that are L1,L2,L3: Level 1 (L1) cache or Primary Cache L1 is the primary type cache memory. The Size of the L1 cache very small comparison to others that is betwee...
Solid-state flash memory is a popular non-volatile memory technology. All types of read-only memory (ROM) devices are also non-volatile. Secondary memory, such as HDDs and SSDs, are routinely designated as non-volatile memory or non-volatile storage. Memory vs. storage Memory and storage ...
Each type of ROM has specific applications, from static data storage to updatable firmware, providing flexibility and functionality across different technological needs.Computer ROM Usage Read-Only Memory is used in various applications where data needs to be permanently stored and not modified frequently...
Random access memory is considered part of a computer's primary memory. It is much faster to read from and write to than secondary storage, such as hard disk drives (HDDs), solid-state drives (SSDs) oroptical drives. However, RAM isvolatile; it retains data only as long as the computer...
Today, the most common type of RAM isDDR-SDRAM, or Double Data Rate Synchronous Dynamic Random-Access Memory. And there are various iterations, including DDR2, DDR3, DDR4, and even DDR5. DDR (double-data rate) allows simultaneous multiple file transfers. The latest version of DDR5-RAM can...
