Question 15

IMEI

Answer 15

International Mobile Equipment Identifier (Used with Global System for Mobiles) - Unique identity number assigned to a GSM device that can be recognized and blocked by the network to which it is connected. It is useful for fraud prevention and to bar access using a stolen phone.

Question 16

IMSI

Answer 16

International Mobile Subscriber Identity - Unique number of up to fifteen digits assigned to each GSM connection, containing country code, network operator code, and mobile device number.

Question 17

KVM switch

Answer 17

Keyboard Video Mouse - A device that allows one to quickly and easily switch between multiple PCs or servers from a single console (Keyboard, Monitor, Mouse setup) for greater efficiency, management, and both cost and space saving. Common scenarios in which a KVM switch is useful include: Home Office

Question 18

MEID

Answer 18

Mobile Equipment Identifier (Used with CDMA) - A globally unique 56-bit identification number for a physical piece of mobile station equipment. Equipment identifiers are “burned” into a device and should be resistant to modification. They are used to facilitate mobile equipment identification and tracking.

Question 19

MIMO

Answer 19

Multiple Input Multiple Output (802.11n) - A wireless technology that uses multiple transmitters and recievers to transfer more data at the same time. All wireless products with 802.11n support MIMO. Technology helps allow 802.11n to reach higher speeds than products without 802.11n.

Question 20

MTBF

Answer 20

Mean Time Between Failures - The average time between repairable failures of a technology product. The metric is used to track both the availability and reliability of a product. The higher the time between failure, the more reliable the system.

Question 21

NAS

Answer 21

Network Attached Storage - Dedicated file storage that enables multiple users and heterogeneous client devices to retrieve data from centralized disk capacity. Users on a LAN access the shared storage via a standard ethernet connection.

Question 22

NAT

Answer 22

Network Address Translation - The process of mapping an internet protocol address to another by changing the header of IP packets while in transit via a router. This helps to improve security and decrease the number of IP addresses an organization needs.

Question 23

NVMe

Answer 23

Non-Volatile Memory express - A new storage access and transport protocol for flash and next-generation SSDs that delivers the highest throughput and fastest response times yet for all types of enterprise workloads.
