Explanation / Answer

Answer 1 :

TRUE , A cellular network or versatile network is a correspondence network where the last link is wireless. The network is circulated over land regions called cells, each served by no less than one settled area handset, yet more ordinarily three cell locales or base handset stations. These base stations give the cell the network scope which can be utilized for transmission of voice, information and others. A phone normally utilizes an alternate arrangement of frequencies from neighboring cells, to keep away from impedance and give ensured benefit quality inside every phone.

Answer 2 :

UMTS , The Universal Mobile Telecommunications System (UMTS) is a third generation mobile cellular system for networks based on the GSM standard. Developed and maintained by the 3GPP (3rd Generation Partnership Project).

Answer 3 :

TCP/IP , The Mobile IP allows for location-independent routing of IP datagrams on the Internet. Every mobile hub is recognized by its street number neglecting its present location in the Internet. Abide far from its home system, a mobile hub is related with a care-of address which recognizes its present location and its place of residence is related with the nearby endpoint of a tunnel to its home specialist. Mobile IP indicates how a mobile hub registers with its home operator and how the home specialist courses datagrams to the mobile hub through the tunnel.

Answer 4 :

TRUE , BYOD security is frequently a test for ventures and SMBs alike. This stems from the way that with a specific end goal to be successful, organizations must apply some type of control over cell phones, tablets, and workstations that are not possessed by the organization but rather are representatives' close to home resources. As BYOD has turned out to be progressively normal and familiarity with security risks has developed, BYOD security approaches are winding up more generally embraced and acknowledged by the two organizations and their worker.
