What is theabbreviation for byte like in megabytes?
B.
Officially, B=byte and b=bit, but this convention is widely ignored, so you can see both MB and mb used as abbreviation for megabytes.
Does freeing up memory improve computer performance?
Computers operate best when they have "system memory" free and are not relying on virtual memory (which uses a hard drive as additional system memory). If you have a system with 1GB of installed system memory, and you are using 1.25GB of allocated memory, then freeing up 0.25GB of used system memory would improve performance by reducing virtual memory usage. Conversely, if you have 2.0GB of installed memory, and you are using 1.25GB of allocated memory, then freeing 0.25GB of used memory would have no appreciable effect since virtual memory is not being used by the system.
Final answer: If you are using virtual memory, then freeing enough memory to eliminate the virtual memory usage will improve performance, but freeing up more than that amount will have no appreciable effect.
What is the full form of NVRAM?
The full form of NVRAM is non-volatile random access memory.
Non-volatile chips do not lose data when the main power is turned off.
A byte is a unit of capacity. A megahertz is a unit of frequency. The two units are incompatible.
What is associative memory explain its advantage?
its also called content addressable memory .Content-addressable memory (CAM) is a special type of computer memory used in certain very high speed searching applications. It is also known as associative memory, associative storage, or associative array
How many Bytes of storage for Sarah?

What is the function of amr slot?
The AMR (Advanced Mobile Phone System) slot is a feature in mobile phones that allows for the insertion of additional modules to enhance functionality. These modules can provide various services such as GPS, Bluetooth, or enhanced battery capacity. The AMR slot enables manufacturers to customize devices and allows users to upgrade or expand their phone's capabilities without needing to replace the entire device.

How many bits are required to address a 4 megabyte?
The minimum number of address lines required to address 4k of memory is 12.
To reach this number, remember that each line has two possibilities and keep doubling as you count off. So one line can be used for two possibilities. Two lines represent four possibilities. Three represent eight. When you get to ten, you have 1024 possibilities. So double to 2048 at 11 and again to 4096 at 12. Or for the shortcut, if you take two to the 12th power, you get 4096.
quote wikipedia:
"Chips are made with a variety of data bus sizes (most commonly 4, 8 or 16 bits), but chips are generally assembled into 168-pin DIMMs that read or write 64 (non-ECC) or 72 (ECC) bits at a time."
answer: 168
