WHAT IS MEMORY BUS?
When input devices send binary data to a CPU, it immediately stores that data
Memory is designed for fast access and typically stores only the data and instructions that are necessary for the currently running programs on a computer
Computers also vary a lot in memory size, usually because of physical size constraints.
High speed communication transfer system, made from wires, conductors, or optical fibers
SECONDARY MEMORY IS ALSO KNOWN AS ... (2 ANSWERS)
microcomputer that's often used by hobbyists to create projects like animated LED displays or bird watchers
File sizes are always measured in
For the simplest of images, computers can use a compression algorithm called
file size compression
The very first network connections re-used the ... of telephone lines, communicating binary data via pulses of electricity.
... compression algorithms reduce the size of files without losing any information in the file, which means that we can reconstruct the original data from the compressed file.
... are techniques that reduce file size by discarding the less important information.
bitmap compression algorithms
image compression algorithms
lossy compression algorithms
lossless compression algorithms
