What is memory in computer Mcq?
The correct answer is Random Access Memory (RAM). Key Points. Computer memory is any physical device capable of storing information temporarily, like RAM (random access memory), or permanently, like ROM (read-only memory).
Which of the memory has highest speed Mcq?
The cache memory is the high speed memory between the main memory and the CPU.
What is cache memory Mcq?
Cache memory, also called CPU memory, is a random access memory that a computer microprocessor can access more quickly than it can access regular RAM. This volatile memory is typically integrated directly with the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU.
Which of the following is main memory Mcq?
The main memory mainly consists of RAM and ROM, where RAM contains the current data and programs and ROM contains permanent programs like BIOS.
What are two types of memory in computer?
There are technically two types of computer memory: primary and secondary. The term memory is used as a synonym for primary memory or as an abbreviation for a specific type of primary memory called random access memory (RAM).
What is the smallest unit of memory?
A byte is the smallest unit of memory used in today’s computing. Bytes consist of eight bits, and a byte is used to encode a single number, letter, or symbol.
Which is fastest memory?
Cache memory is the fastest system memory, required to keep up with the CPU as it fetches and executes instructions. The data most frequently used by the CPU is stored in cache memory.
Is ROM primary or secondary storage?
Unlike RAM, Read Only Memory (ROM) delivers both non-volatile and permanent primary storage. ROM retains its contents even if the device loses power. You cannot change the data on it, you can only read it. ROM is a more reliable form of storage, and it will often boot instructions and other mission-critical data.
Which is the fastest memory?
Cache memory is the fastest system memory, required to keep up with the CPU as it fetches and executes instructions. The data most frequently used by the CPU is stored in cache memory. The fastest portion of the CPU cache is the register file, which contains multiple registers.
What is the largest memory unit?
One yottabyte is equal to 1, 000 zettabytes. It is the largest SI unit of memory measurement. A yottabyte is 1024 ZettaBytes or 1, 000, 000, 000, 000, 000, 000, 000, 000 bytes and is abbreviated as “YB”.
What is computer memory size?
The memory capacity of a device is commonly expressed in bytes, kilobytes, megabytes, gigabytes or terabytes. A device’s memory capacity can be obtained from either the operating system or motherboard. In most cases, the architecture of the motherboard of the device influences the memory capacity of the machine.
Which is the smallest memory?
What is memory cache?
Cache memory is a chip-based computer component that makes retrieving data from the computer’s memory more efficient. It acts as a temporary storage area that the computer’s processor can retrieve data from easily.
What is called ROM?
ROM is an acronym for Read-Only Memory. It refers to computer memory chips containing permanent or semi-permanent data. Unlike RAM, ROM is non-volatile; even after you turn off your computer, the contents of ROM will remain. Almost every computer comes with a small amount of ROM containing the boot firmware.
