As quoted from Google Books, "Word size refers to the number of bits that a microprocessor can manipulate at one time."
depends on your processor type and the workload on it.
Parallelism
It means how fast something changes, and is obtained by dividing some quantity by a unit of time. Examples of rates: Velocity is distance / time. Acceleration is velocity / time. Bandwidth is number of bits transferred / time.
Perhaps you mean 4 bits at a time, I guess its a nibble
As quoted from Google Books, "Word size refers to the number of bits that a microprocessor can manipulate at one time."
Word length is the number of bits that can be processed at one time.
The number 64 in the Nintendo 64 refers to how many bits the CPU can process at a time. Many people mistakenly think the 64 refers to the storage space, but that is incorrect.
The number of bits that can be processed at one time is known as a processor's word width (but other names are also used, such as the processor's bus width).The word width varies between processor models. Early processors processed 4 bit words, then 8-bit processors became common. Today's processors tend to support 16, 32 and 64 bit words. The word width is not necessarily a power of two; some processors are designed for 24-bit words, for example.
In the computer networking industry the abbreviations BER mean Bit Error Rate. BER is the percentage of bits with errors collected divided by the total number of bits that have been transmitted, received or processed during a recorded time period or time frame.
Bit Interval: The time required to send one signal bit. Bit Rate: The number of bits that are conveyed or processed per unit of time. (Example: 100MB/sec)
8bit 16 bits 32 bits and 64 bits and 128 bits imply a broadside [parallel] output of that many bits of digital information on a buss output. these bits represent a word output. therefore the longest the word the more information can be processed at a time imply more bits the faster the computer or data flow.
A unit of data that contains a fixed number of bytes or bits and represents the amount of data a CPU processes at one time is known as a "word." The size of a word can vary depending on the computer architecture, typically ranging from 16 to 64 bits. Words are fundamental to a CPU's operation, influencing how data is retrieved, processed, and stored in memory.
Rate refers to frequency, while size refers to the amount. Thus, Sampling Rate is measured in Hertz (number of times per second a sample is taken), and Sampling Size is measured in Bits (number of binary digits of information taken at a single time). Thus, if you Sample at 10 Hz/8 bits, that means you take 8 bits of information, 10 times per second.
Bit rate would be the number of bit processed per time frame, normally per second Old modems commonly worked as 4800 Baud or 9600 Baud which would be 4800 bits per second and 9600 bits per second respectively
