Question 1

NAPT

Answer 1

(Network Address Port Translation)

Similar to NAT, it (or PAT or NAT overloading)maps private host IP addresses onto a single public IP address. Each host is tracked by assigning it a random high TCP port for communications.

Question 2

NAS

Answer 2

(Network Attached Storage)

A storage device with an embedded OS that supports typical network file access protocols (TCP/IP and SMB, for instance).These may be subject to exploit attacks(though using an embedded OS is often thought of as more secure as it exposes a smaller attack “footprint”). The unauthorized connection of such devices to the network is also a concern.

Question 3

NAT

Answer 3

(Network Address Translation)

A network service provided by router or proxy server to map private local addresses to one or more publicly accessible IP addresses. NAT can use static mappings but is most commonly implemented as Network Address Port Translation (NAPT) or NAT overloading, where a few public IP addresses are mapped to multiple LAN hosts using port allocations.

Question 4

NetBT

Answer 4

(NetBIOS over TCP/IP)

NetBIOS that was re-engineered to work over the TCP and UDP protocols.

Question 5

NFC

Answer 5

(Near Field Communications)

A Standard for peer-to-peer (2-way) radiocommunications over very short (around4”) distances, facilitating contactless payment and similar technologies. NFC is based on RFID.

Question 6

NIC

Answer 6

(Network interface Card)

An expansion card that enables a PC to connect to a LAN. Also referred to as a network adapter.

Question 7

NIST

Answer 7

(National Institute of Standards and Technology)

Develops computer security standards used by US federal agencies and publishes cybersecurity best practice guides and research.

Question 8

NLA

Answer 8

(Network Level Authentication)

An RDP technology requiring users to authenticate before a server session is created.

Question 9

NVMe

Answer 9

(Non-volatile Memory Express)

An interface for connecting flash memory devices, such as SSDs, directly to a PCI Express bus. NVMe allows much higher transfer rates than SATA/AHCI.

Question 10

NVMHCI

Answer 10

(Non-Volatile Memory Host Controller Interface specification)

A logical interface used by PCIe-based SSD drives to communicate with the bus.
