What is the size of the address bus in 80286?
24-bit
What is the size of control bus in 8085 microprocessor?
8 Bit
What is the length of CSR in 80286?
80286 uses the 16-bit content of a segment register as a selector to address a descriptor stored in the physical memory.
What is the size of the bus in first micro processor?
It was the first 16-bit processor having 16-bit ALU, 16-bit registers, internal data bus, and 16-bit external data bus resulting in faster processing.
What are the three types of buses in microprocessor?
Three types of bus are used.
- Address bus – carries memory addresses from the processor to other components such as primary storage and input/output devices.
- Data bus – carries the data between the processor and other components.
- Control bus – carries control signals from the processor to other components.
What is the data bus?
A data bus is a system within a computer or device, consisting of a connector or set of wires, that provides transportation for data. Different kinds of data buses have evolved along with personal computers and other pieces of hardware.
What is bus size?
A computer bus (often simply called bus) is part of most computers. The size or width of a bus is how many bits it carries in parallel. Common bus sizes are: 4 bits, 8 bits, 12 bits, 16 bits, 24 bits, 32 bits, 64 bits, 80 bits, 96 bits, and 128 bits. Computers use such buses to link: CPU to on-board Memory.
What are characteristics of bus?
A bus is characterized by the amount of information that can be transmitted at once. This amount, expressed in bits, corresponds to the number of physical lines over which data is sent simultaneously. A 32-wire ribbon cable can transmit 32 bits in parallel.
What is the difference between a bus and a port?
A computer port is a slot or a connection point on a computer, similar to a plug point, where a device can be connected. The system bus, also called the memory bus, makes a connection between the CPU and the main memory of the computer that resides on the motherboard.
What is the purpose of port and bus?
A PS/2 port found on the back of computers that allows a keyboard and mouse with a PS/2 connector to be connected to the computer. The bus connects major components like processor, memory and I/O internally and also connects the different external devices and ports thus expanding the computer’s capabilities.
What does bus mean in USB?
‘Bus powered’ usually refers to USB connected devices which take their power from the USB connection and don’t require an external power source. For example you might have a USB Hub or Repeater to extend your USB distance or number of connected devices.
What is the difference between a USB and a USB-C?
The USB-A has a much larger physical connector than the Type C, Type C is around the same size as a micro-USB connector. Unlike, Type A, you won’t need to try and insert it, flip it over and then flip it over once more just to find the right orientation when trying to make a connection.
