Q

SNMP

A

A widely used network monitoring and control protocol.

Simple Network Management Protocol

Data are passed from SNMP agents, which are hardware and/or software processes reporting activity in each network device (hub, router, bridge, etc.) to the workstation console used to oversee the network. The agents return information contained in a MIB (Management Information Base), which is a data structure that defines what is obtainable from the device and what can be controlled (turned off, on, etc.). Originating in the Unix community, SNMP has become widely used on all major platforms.

CIFS

A

The file sharing protocol used in Windows.

Common Internet File System

It evolved out of the SMB (Server Message Block) protocol in DOS, which is why the terms CIFS/SMB and SMB/CIFS are commonly used. The word “Internet” in CIFS does not refer to the global Internet but to generic internetworking.

Q

POP3 or IMAP4?

(ANSWER) is a simple system with limited selectivity. Incoming messages and attachments are downloaded when users check their mail, and (ANSWER) is typically configured to delete the messages on the server after downloading. If the user opts to not delete them, the messages will download again the next time mail is checked.

Q

POP3 or IMAP4?

(ANSWER) has more options than (THE OTHER ONE). For example, it can download only the message headers, which have only to/from addresses and subject. An essential option in the early days of dial-up, the user then chooses which messages and attachments to download. (ANSWER) also keeps the messages on the mail server in synchronization with the downloaded messages in the client. Users can then decide when and which messages to delete on the server.

Q

The use of multiple transmitters and receivers (multiple antennas) on wireless devices for improved performance.

A

MIMO

Multiple Input/Multiple Output

When two transmitters and two or more receivers are used, two simultaneous data streams can be sent, which double the data rate. Multiple receivers alone allow greater distances between devices. For example, the IEEE 802.11n (Wi-Fi) wireless standard uses MIMO to increase speed to 100 Mbps and beyond, doubling at minimum the 802.11a and 11g rates. MIMO antennas are also used in WiMAX and LTE.

Q

WISP

A

An Internet service provider (ISP) that transmits wireless. Using Wi-Fi or other radio frequencies licensed by the government, WISPs provide “last mile” connectivity directly to homes and businesses.

Wireless Internet Service Provider

Carriers such as AT&T and Verizon are technically “mobile WISPs;” however, they are generally called “cellular carriers” or “mobile carriers.” In contrast, “fixed wireless WISPs” mount antennas on tall buildings with line of sight to their customers or to other antennas that relay the signals around obstacles. WISPs became popular in rural and outlying areas, because they were the only high-speed Internet connection available; however, they are also deployed in urban areas and compete with the major ISPs.

Q

True or False?

BIOS/UEFI passwords improve the security of a PC. These low-level passwords may, for example, prevent unauthorized users to proceed when the computer is powered on (Supervisor password), or restrict the scope of changes a user can make in the BIOS/UEFI interface (User password).

Why?

A

False

The security provided by BIOS/UEFI passwords is relatively weak. These passwords can be bypassed or reset by experienced attackers through various methods, such as removing the CMOS battery, using jumper pins on the motherboard, or exploiting vulnerabilities in the BIOS/UEFI firmware.

52
Q

A (BLANK) cable is a type of twisted pair cable that is used in local area networks to connect a computer to a network hub such as a router. This type of cable is an alternative to wireless connections where one or more computers access a router through a wireless signal.

A

Straight-through

On a Straight-through cable, the wired pins match. Straight-through cables use one wiring standard: both ends use T568A wiring standard or both ends use T568B wiring standard.

53
Q

A (BLANK) Ethernet cable is a type of Ethernet cable used to connect computing devices together directly. It is most often used to connect two devices of the same type: e.g. two computers (via network interface controller) or two switches to each other.

A
