2 127 bits, 2 124 bytes – IBM Eagle: 2 131: 10 39: 2 131 bits, 2 128 bytes – theoretical maximum volume size of the ZFS filesystem. [26] [27] [28] 2 150: 10 42 ~ 10 42 bits – the number of bits required to perfectly recreate the natural matter of the average-sized U.S. adult male human brain down to the quantum level on a computer is ...
The bit time has nothing to do with the time it takes for a bit to travel on the network medium but has to do with the internals of the NIC. To calculate the bit time at which a NIC ejects bits, use the following: bit time = 1 / NIC speed To calculate the bit time for a 10 Mbit/s NIC, use the formula as follows:

A byte is a bit string containing the number of bits needed to represent a character. On most modern computers, this is an eight bit string. Because the definition of a byte is related to the number of bits composing a character, some older computers have used a different bit length for their byte. [2]
The size of the "byte offset" from the address being translated is still 12 bits, so total physical address size increases from 32 bits to 36 bits (i.e. from 20+12 to 24+12). This increased the physical memory that is theoretically addressable by the CPU from 4 GB to 64 GB.
On devices like modems, bytes may be more than 8 bits long because they may be individually padded out with additional start and stop bits; the figures below will reflect this. Where channels use line codes (such as Ethernet , Serial ATA , and PCI Express ), quoted rates are for the decoded signal.
A bitstream (or bit stream), also known as binary sequence, is a sequence of bits. A bytestream is a sequence of bytes . Typically, each byte is an 8-bit quantity , and so the term octet stream is sometimes used interchangeably.
The bit length of each word defines, for one thing, how many memory locations can be independently addressed by the processor. In cryptography , the key size of an algorithm is the bit length of the keys used by that algorithm, and it is an important factor of an algorithm's strength.
