Answers

1.

Correct Answers = B, C, and D

You can connect two computers together with a serial cable, an Ethernet thinnet 10Base2 cable, or a parallel cable. A 6-pin mini-DIN connector is used to connect a PS/2 mouse or keyboard to a computer.

2.

Correct Answer = B

A parallel port uses parallel transmission methods to transmit or send data 1 byte at a time to a peripheral device. A serial port transmits data one bit at a time.

3.

Correct Answer = C

With Half Duplex transmission, data can be transmitted in both directions but can only be transmitted in one direction at a time. Full Duplex is simultaneous transmission where data or voice can be transmitted at exactly the same time.

4.

Correct Answers = A and D

A parallel port on the back of a computer system is a female DB25 connector that accepts a DB25-pin male connector on one end of a parallel cable. The other end of a parallel cable has a 36-pin male Centronics D-shell connector that connects to a Centronics connector located on the back of a printer or device. A DB9-pin connection is used for connecting a modem or serial mouse to the back of a system. RS232C is a serial port standard.

5.

Correct Answer = D

A game or MIDI female port on the back of system has two levels of 15 total pins that accept a male connector with two levels of 15 total pins.

6.

Correct Answer = A

The fastest technology available for printers today is SCSI.

7.

Correct Answer = A

FireWire is much faster than USB or parallel; it supports data transfer rates of 100Mbps to 400Mbps.

8.

Correct Answer = D

Category 5 UTP supports 100BaseT or 100BaseTX. Category 2, 3, and 4 cable types do not support 100BaseT.

9.

Correct Answer = A

The minimum cable type needed to support 10BaseT is Category 3. An RJ-11 phone connector is used for earlier categories of UTP to connect a modem or your phone to a typical phone jack.

10.

Correct Answer = B

The newest addition to the IEEE 1284 standard for bi-directional communications and printing is the Type C Mini 36-pin parallel connector.

11.

Correct Answers = A, B, and C

Parallel printer ports support bi-directional as well as Enhanced Parallel Port (EPP) application data transmissions. They are associated with the IEEE 1284 parallel standard that is used to connect a computer to peripheral devices such as printers.

12.

Correct Answer = D

The IEEE 1394 standard references FireWire high-speed serial transmissions of up to 400Mbps (in version 1394a) and 800Mbps (in version 1394b). You better know the difference between IEEE 802.11, IEEE 1284, IEEE 1394, and RS232 for the real exam!

13.

Correct Answer = B

FireWire is Plug-and-Play-compatible and hot swappable. It also allows up to 63 devices to be connected to one port. A Plug-and-Play system will use the process known as enumeration to assign an address and auto detect any FireWire-connected devices.

14.

Correct Answer = C

Fiber-optic cables use special ST and SC type connectors to attach to NICs and fiber-optic ports. These connectors are precisely crafted and specially designed to suit fiber-optic cable connection requirements.

15.

Correct Answer = D

The majority of infrared (IR) transmissions occur between two computers or a single computer and an infrared-enabled device such as a printer or PDA. The sending host or device uses an infrared transmitter or “emitter,” which sends pulses of infrared light to the receiving host or device, which accepts with an infrared receiver.

16.

Correct Answer = D

In order for your system to use Infrared, IR, or IrDa (same thing), support must be enabled in your system’s BIOS.

17.

Correct Answer = B

Wireless access points are sometimes referred to as transceivers because they can transmit and receive RF signals. They are the “hub” of wireless networks.

18.

Correct Answer = A

Before you install a wireless network solution into an existing building or between existing buildings (building to building) you should first have a professional site survey conducted by certified RF (Radio Frequency) engineers.

19.

Correct Answer = B

Single-mode fiber optic, also referred to as monomode fiber, is a fiber technology meant for very long-distance data transmissions.

20.

Correct Answer = D

Multi-mode fiber uses LEDs (light emitting diodes) to generate signals of light into the core fibers for transmission over fiber media. This mode of fiber is designed to carry many light signal rays or “modes” at the same time over a shorter distance than single-mode.

21.

Correct Answer = B

CAT6 cabling is built using 23-gauge conductor wire. The CAT6 cabling standard is rated up to 550M or 1000M.
