Why the te10 mode is the dominant mode in rectangular waveguide?
TE10 mode is the dominant mode with a>b, since it has the lowest attenuation of all modes. Either m or n can be zero, but not both.
What mode involves the CPU and is slower than DMA mode?
PIO
Cannot be run in dos mode?
Try to run it in Windows mode.
What are the different operating modes of 8255?
the different operating modes of 8255 are as follows 1)bsr mode 2)i/o mode -bsr mode can only program using port c and is used when d7=0 in control word -i/o mode can be used for all ports a,b,c(upp),c(low) respectively and is used when d7=1
What is the control word for 8255 PPI in BSR mode to set bit PC3?
it's 00000111 binary = 07 H
What is bsr mode?
this mode is related to only port c.the bits of port c can be controlled directly by the microcontroller

What is the use of IC 8255?
The Intel 8255 is a general purpose programmable Input/Output device which is designed for use with all Intel and most other microprocessors. It provides 24 Input/Output pins which may be individually programmed in 2 groups of 12 and used in 3 major modes of operation. In MODE 0, each group of 12 I/O pins may be programmed in sets of 4 and 8 to be inputs or outputs. In MODE 1, each group may be programmed to have 8 lines of input or output. 3 of the remaining 4 pins are used for handshaking and interrupt control signals. MODE 2 is a strobed bi-directional bus configuration. The 8255 is a 40 pin integrated circuit (IC), designed to perform a variety of interface functions in a computer environment. The 8255 wasn't originally designed to be connected to the Z80. It was manufactured by Intel for the 8080 microprocessor.
