The correct answer is (a) Master node is sending data to a slave

The EXPLANATION: There may be FOUR potential modes of operation for a given bus device, although most devices only use a single role and its TWO modes:

-> Master TRANSMIT – Master node is sending data to a slave

-> Maser receive – Master node is receiving data from slave

-> Slave transmit – lave node is transmitting data to master

-> Slave receive – Slave node is sending data to master.

Right ANSWER is (b) SPI

For explanation: The typical applications of SPI protocol are secure DIGITAL cards and liquid crystal DISPLAYS.

Correct option is (a) Overrun ERROR

Easy explanation: An over run error occur when the receiver cannot process the character that just came in before the next one arrives. If the CPU or DMA controller does not SERVICE the UART QUICKLY enough and the buffer BECOME full, an over run will occur, and incoming will be LOST.

The correct answer is (c) Network Interface Card

The best explanation: A MAC address is GIVEN to an adapter when it is manufactured. It is hardwired or hard-coded ONTO your computer’s NIC and it is UNIQUE to it. Something called the ARP (Address Resolution Protocol) translates an IP address into MAC address.

The CORRECT option is (d) 32 bit

The explanation: The FORMAT of an IP address is a 32-bit numeric address written as FOUR numbers separated by periods. Each number can be zero to 255. For EXAMPLE, 1.160.10.240 could be an IP address.

The correct option is (b) BYTE streams

The explanation is: Some applications PREFER to receive byte stream INSTEAD of packets; the transport layer allows for the TRANSMISSION of byte-orientated data stream if REQUIRED.

The CORRECT choice is (d) 3 types

For explanation: Routing deals with determining how packet will routed (TRANSFERRED) from SOURCE to DESTINATION. It can of three types : 1. Static

2. Dynamic

3. Semi Dynamic.

Correct answer is (c) INTERNET PROTOCOL

Explanation: Internet protocol and Netware IPX/SPX are the most common protocols ASSOCIATED with the network LAYER.

Right choice is (c) Limited

Best explanation: BINARY data must be FIRST base64 encoded before it can be TRANSMITTED in band. Therefore, any SIGNIFICANT amount of binary data is best transmitted out of band, using in band message to coordinate.

Correct option is (b) False

Best explanation: The Internet of Things cannot SPREAD as long as it can be exploited by hackers willy-nilly. CoAP does not just pay lip service to security, it actually provides strong security. CoAP’s DEFAULT choice of DTLS parameters is equivalent to 3072-bit RSA keys, yet still RUNS fine on the SMALLEST nodes.

Correct answer is (d) 2 lines

Explanation: SPI USES separate clock and data lines, along with a SELECT LINE to choose the device we wish to TALK to.

Right CHOICE is (d) Multicast support, Low over head, and simplicity

The explanation is: Multicast, low overhead, and simplicity are extremely important for INTERNET of Things (IoT) and Machine-to-Machine (M2M) devices, which tend to be deeply EMBEDDED and have much less MEMORY and power supply than TRADITIONAL internet devices have.

Right option is (d) 16

The explanation is: The STANDARD implementation USES a prescalar from any CLOCK source and a fixed second clock divider which is USUALLY a divided by 16.

The correct ANSWER is (C) 1/32 to 1/63 times of BRCKL

To elaborate: The timing of x is 1/32 to 1/63 of BRCLK, but at least BRCLK, DEPENDING on the division on the division RATE of the baud rate generation.

The correct answer is (a) POSITIVE EDGE

The explanation is: The RECEIVE operation is INITIATED by the RECEIPT of a valid start bit. It consists of a negative edge at URXD, followed by the taking of majority vote from three samples, where 2 of the samples must be zero.
