For multicore processors to be used effectively, computers must understand how to divide tasks into parts that can be distribute
AnnyKZ [126]

Answer: parallel processing

Explanation:

Parallel processing is the process by which the processor has the capacity to execute parallel instruction at the same time. This is possible only by assigning the different task to the different cores present in the cpu. So a cpu with multiple cores are able to process multiple task as the same time parallel.

In step 4 of the CSMA/CA protocol, a station that successfully transmits a frame begins the CSMA/CA protocol for a second frame
DerKrebs [107]

Answer:

There could be a collision if a hidden node problem occurs.

Explanation:

CSMA/CA(carrier sense multiple access/ collision avoidance) is a multiple access method in wireless networking, that allows multiple node to transmit. Collision avoidance of this method is based on preventing signal loss or downtime as a result of collision of transmitting multi signals.

If a node at step 4(transmit frame) sends the first frame, the node still needs to send a RTS(request to send) and to receive a Clear to send (CTS) from the WAP, the is to mitigate the issue of hidden node problem as all frame are treated as unit, so other listening nodes, not detected would seek to connect and transmit as well.

timama [110]

Answer:

PLCs (Programmable logic controller) were original designed as replacement for relay control panels.  Relay is another word for a switch. Relay control panels were made for the control of electronic instrumentents or devices. Later on PLCs were made to replace these timers and relay control panels. PLCs are more reliable, flexible and can work better in the harsh environmental situations then the relay control panels.

You’re trying to cast a video presentation from your tablet to a projector for a training session with some new hires. Although
Vikki [24]

Answer:

Troubleshooting steps to take:

  1. Restart the tablet
  2. Restart the projector

Explanation:

When such problems occur, the basic and quick troubleshooting step is to restart the device or devices involved.

  1. Restart the tablet: This could come in handy regarding this problem. The inability to connect to the projector could be due to the inability of a specific service or driver needed for the projector. Restarting the tablet will load up the drivers and services again to enable smooth connections. When a restart is done, bugs are fixed, internet connection is rectified, memory leaks are stopped, performance is aided, the RAM (Random Access Memory) is flushed or cleaned. This should resolve the problem, however, if not, try number 2.
  2. Restart the projector: There are driver software on projectors, and due to one system failure or another, these software may fail to load. This could affect its connection to another device. As done in (1), restarting the projector will fix those bugs and load up, which should solve the connection issue.
