serial interface
What else can I help you with?
What type of port that transfers more than one bit at a time?
A parallel port is capable of transferring more than one bit at a time. It can transfer multiple bits simultaneously using multiple data lines.
1what type of interface connects a device to the system unit by transmitting data one bit at a time?
A serial port is an interface in which one bit of data is transmitted at a time.
How many bits does a serial port transmit at a time?
Serial ports transmit data one bit at a time, which is why they are becoming obsolete.
Consider two microprocessors having 8 and 16bit wide external data buses respectivelyThe two processors are identical other wise and their bus cycles take just as longsuppose all instructions?
During a single bus cycle, the 8-bit microprocessor transfers one byte while the 16-bit microprocessor transfers two bytes. The 16-bit microprocessor has twice the data transfer rate.
Which motherboard feature controls the amount of data that a CPU transfers at one time?
the internal data path the address bus the clock speed the cache
What symmetric algorithm encrypts data one bit at a time?
Example of a stream cipher
What is the definition of parallel computing?
The definition of parallel computing is the processing of data many bits at a time as opposed to serial computing which is the processing of data one bit at a time.
What is the difference between serial and parallel data transmission?
one bit at a time vs. a group of several bits at a time.
Consider a hypothetical 32-bit microprocessor having 32-bit instructions composed of two fields the first byte contains the opcode and the remainder the immediate operand or an operand address What?
• What is the maximum directly addressable memory capacity (in bytes)? 2(32-8) = 16,777,216 bytes = 16 MB • Discuss the impact on the system speed if the microprocessor data bus has • a 32-bit local address bus and a 16-bit local data bus. Instruction and data transfers would take three bus cycles each - one for the address and two for the data. • a 16-bit local address bus and a 16-bit local data bus. Instruction and data transfers would take four bus cycles each - two for the address and two for the data. • How many bits are needed for the program counter and the instruction register? 24 bits for the PC (24-bit addresses), 32 bits for the IR (32-bit addresses)
Which kind of interface transmits one bit at a time?
Serial interface transmits one bit at a time, typically using a single data line. Examples include USB, RS-232, and SPI interfaces.
What technology enables fast data transfers over the pstn offering a higher volume of data flow in one direction?
adsl
Single bit error in data transmission?
A single bit error is when only one bit within a given data string is in error. It affects only one character within a message
