Как работает компьютерная память

What is RAM?

• Operative memory is a device for storing long-term information

• Operative memory is a program for virus protection

• Operative memory is a type of computer monitor

• Operative memory is a type of computer memory used for temporary storage of data and instructions that the processor is currently working with.

What types of RAM exist?

What is a hard disk?

• Device for storing data on a computer using optical discs

• Software for protecting a computer from viruses

• Device for storing data on a computer using magnetic discs

• Type of keyboard with soft keys

How are data written to the RAM?

• Through transferring data through data and address buses

• Through the use of magnetic fields

• Through converting data into analog signal

• Through transferring data through data and address buses

What is cache memory?

• Cache memory is a small but very fast memory used to temporarily store data in order to speed up access to it.

• Cache memory is a type of RAM

• Cache memory is used to store large amounts of data

• Cache memory is slow memory that slows down access to data

What units of measurement are used for memory volume?

• Bytes, terabytes, petabytes

• Bits, gigabits, teragigabits

• Kilobits, megagigabits, petabits

• Bytes, kilobytes, megabytes, gigabytes, terabytes and so on.

What is virtual memory?

• Virtual memory is a computer monitor

• Virtual memory is a computer processor

• Virtual memory is a mechanism that allows the operating system to use part of the hard drive as temporary storage for data when physical memory (RAM) is exhausted.

• Virtual memory is a computer graphics card

How does the process of reading data from memory work?

• The central processor sends a request to read data from memory, the memory controller selects the necessary cell, transfers the data to the data bus, the data moves along the bus to the processor, the processor receives the data and starts processing it.

• The processor transfers data to the data bus

• Data moves along the bus to the memory controller

• The central processor sends a request to write data to memory

What is the difference between RAM and ROM?

• RAM is permanent while ROM is temporary.

• RAM is volatile while ROM is non-volatile.

• RAM is read-only while ROM is read-write.

• RAM is non-volatile while ROM is volatile.

What factors affect the speed of computer memory?

• Type of memory, capacity, clock speed, CAS Latency, bandwidth

• Case color

• Type of keyboard

• Monitor manufacturer
