In bit-plane slicing if an image is represented by 8 bits and is composed of eight 1-bit plane, with plane 0 showing least significant bit and plane 7 showing most significant bit. Then, which plane(s) contain the majority of visually significant data.
The IA-32 processor can switch between 16 bit operation and 32 bit operation with the help of instruction prefix bit.
The shift register shown in the figure is initially loaded with the bit pattern 1010. Subsequently, the shift register is clocked, and with each clock pulse the pattern gets shifted by a one-bit position to the right With each shift, the bit at the serial input is pushed to the leftmost position (MSB) After how many clock pulses will the content of the shift register become 1010 again?
The bit sequence 0010 is serially entered (right – most bit first) into a 4-bit parallel out shift register that is initially clear. What are the Q outputs after two clock pulses?
Consider an 8-bit ALU with a 4-bit status register. The four status bits are symbolized by C, S, Z, and V which stands for carry, sign, zero, and overflow, respectively. Let A= 1111 0000 and B = 0001 0100 and ALU performs A - B. Which of the following represents the state of 4-bit status register?
Consider the three-way handshake mechanism followed during TCP connection establishment between hosts P and Q. Let X and Y be two random 32-bit starting sequence numbers chosen by P and Q respectively. Suppose P sends a TCP connection request message to Q with a TCP segment having SYN bit = 1, SEQ number = X, and ACK bit = 0. Suppose Q accepts the connection request. Which one of the following choices represents the information present in the TCP segment header that is sent by Q to P?
A message consisting of 2400 bits is to be passed over the Internet. The message is passed to the transport layer which appends a 150-bit header, followed by the network layer which uses a 120-bit header. Network layer packets are transmitted via two networks, each of which uses a 26-bit header. The destination network only accepts up to 900 bits long. The number of bits, including headers delivered to the destination network, is
