The correct answer for the given question is true .
Explanation:
SQL is an Structural query language that is used for accessing the database basically it is an query language which is used for communicating with database by executed the query .
The following are the function of SQL
SQL can insert the data into database
it can update the record into database
SQL can retrived the database.
We do not use SQL for writing application it is only used to accessing the database
For create application we can use programming language Like PHP,ASP,JAVA ,PYTHON.etc.
Answer:
c. traffic shaping
Explanation:
A traffic shaping system is one that allows to adapt the incoming data traffic that comes from some node of the network giving it a special treatment called conformation of accepted traffic and thus allowing the frames to be forwarded through the network of data under traffic rules without having gone through some traffic shaping method, this can be detected as non-conforming traffic at the edge of access to the discarded metropolitan network.
Traffic shaping is a mechanism that alters the traffic characteristics of the cell flow of a connection to achieve better network efficiency while maintaining QoS objectives or in order to ensure that the cell flow conforms to traffic parameters according to the leaky bucket algorithm configuration of the traffic contract. Traffic shaping can be used in ATM, for example, to reduce peak speed, limit the length of the burst by means of adequate spacing of cells over time. The use and location of this function is network specific.

Answer:
d. Flash
Explanation:
A flash memory can be defined as an electronic non-volatile memory chip (storage medium) that is typically used on computer systems and other digital devices such as routers, USB flash drives, switches, digital cameras, mp3 players etc. A flash memory is an electronically erasable programmable read only memory (EEPROM) and as such data saved (written) on it can be erased electronically. Also, a flash memory do not require a source of power (electricity) to save or retain data through the use of a floating gate MOSFET (FGMOS) or floating gate transistor.
In this scenario, you are designing an internet router that will need to save it's settings between reboots. The type of memory that should be used to save these settings is a flash memory because it does not require power to write or save data.
