Answer: False
Explanation: Software engineering is the designing, analyzing, creating the software application as per the requirement of the user. The programming languages is the base for the designing of the application the software engineering field.
At the time of building system ,there is the requirement of many resources for the development.There is the requirement of the software skills, programming knowledge, resources and tools for the working and designing.Thus, there are different resources, people,skills processes, problem solving skill etc required for the building of the system.

40. External Peripherals of a Computer systems are the following:
-> Keyboard – this is an input device
-> Mouse – This is an input device also
-> Printer – this is an output device
-> Flashdrive – This is a storage device
-> Monitor – this is an output device
-> external hard drive – this is a storage device
Output device are those devices that communicate the results of the data processing to the user
Input device are those device that communicate the results of the data processing to the computer system
Storage device are those device that stores data.
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.
