Chapter 1 Review Questions

Application level of the TCP/IP models the Applications,Presentation, and Session layers from the OSI model.

User authentication: The username and password that authenticates the users in FTP.

SimpleMailTransferProtocol (SMTP)

PostOfficeProtocolVersion3 (POP3) is designed for intermittent connectivity or InternetMessageAccessProtocolvs4 (IMAP4) which is used more often, keeping all mail on central server.

HypertextTransferProtocol (HTTP), used to communicate b/ a browser and a web server.

HypertextTransferProtocolSecure (HTTPS), secure side which data is encrypted sing TLS/SSL. (TransportLayerSecurity/SecureSocketsLayer)

Netscape

Session Initiation Protocol (SIP), create phone and cancelling calls.

Real-Time Transport Protocol (RTP), digitizes voice and sends to other side.

Real-Time Transport Protocol

Routable is a communications protocol using both a network address and a device address, a non rout protocol only uses device address

Router

Router

Domain Name system is a service that maps domain names to IP addresses

A computer quests access to a domain nae through a switch to contact the local Name server. If the name server has a record for the requested domain name in its tables it will transmit the info back to the computer with the right IP address to get the domain through the switch. If not it will query other DNS servers for the right record and well send back to computer.

Dynamic Host Configuration Protocol and essentially assigns IP address to computers.

DHCPDISCOVER - client requests and IP address from DHCP server when connected to network

DHCPOFFER - DHCP server responds with an offer of an IP address

DHCPREQUEST - Client requests to accept the offer

DHCPACK - DHCP server responds acknowledgement

A telecommunications cablings standard for commercial buildings.

Panel of network ports that connects cabling in a LAN.

Connects different devices together without use of crossover cables such as MDI to MDI or MDIX to MDIX

Standard of industry speeds for up to 1Gbps

Supports up to 10Gbps speeds for data transfer

5x more expensive b/c its used to run cable inside of ventilation ducts or ceilings that act as ventilations. It has a coating that makes it non toxic if it burns. Cat5 or Cat6 are toxic when burned.

Fiber optics utilizes the visible spectrum, transmission by light.

No, because it has no RadioFrequency signal.

Short range communication for in the inside of a building or a building that is right next to each other.

Lights like LEDs can be used as a light source for multimode fiber optics.

Generally used for long range communication, up to 100 km without processing.

Singlemode fiber uses an expensive light source, laser beams

These calbes were used in older ethernet networks, coaxial cabling has been used for years and years in the past.

The twisted pair copper cabling uses conductor pairs that are twisted.

Shielded Twisted Pair (STP) has additional shielding that protects against interference. It requires the use of can electrical ground. An Unshielded Twisted Pair (UTP) has no attritional shielding. it is the most common twisted pair cabling.

Unshielded Twisted Pair (UTP) is the most common form of cabling for Local Area Networks

Electronic Industries Alliance: alliance of trade associations that develops the cabling standards for the industry. Their standards start with: RS# or EIA#

Telecommunications Industry Association, they handle the telecommunications aspect. Standards, market analysis, trade shows, government affairs. Their standards start with: ANSI, TIA, or EIA568

The first standardized categories, it was used to support older category systems 10Mbit/s Ethernet and 4Mbit/s Token Ring.

Cat5e is updated Cat5 and supports 1 Gbit/s Ethernet. Cat 5 supports 100 Mbit/s Ethernet

In a building that has high data traffic such as a data center.

An Ethernet straight through cable is a patch cable that is usually used to connect laptops and desktops directly to a jack or to an Ethernet device. You would use a straight through cable when connecting devices.

A crossover cable allows for two of the same interfaces to connect together without interruption. You would use one when you connect MDI to MDI which refer to workstation to workstation, or when you connect MDIX device to another MDIX device which is network switch to network switch.

I would use a crossover cable to conect two CSU/DSU devices.

Regular TWP cable can give off toxic fumes when ignited. Must be cautious.

Power is required to operate the medial converter that converts electrical signals in the copper wire to the light waves in the fiber.

Yes. Almost any type of media can be converted to any other type of media as long as you have the right devices in use.

RG-8U

328 ft (100m)

100BASE-T4 (four pairs of telephone twisted pair wire)

100BASE-TX (two pairs of data grade twisted-pair wire)

328 ft (100m)

100BASE-T4 (four pairs of telephone twisted pair wire)

100BASE-TX (two pairs of data grade twisted-pair wire)

100BASE-FX (a two-strand optical fiber cable)

This designation is an Institute of Electrical and Electronics Engineers shorthand identifier. The "100" in the media type designation refers to the transmission speed of 100 Mbps. The "BASE" refers to baseband signalling, which means that only Ethernet signals are carried on the medium.

The "T4," "TX," and "FX" refer to the physical medium that carries the signal. (Through repeaters, media segments of different physical types can be used in the same system.)

The TX and FX types together are sometimes referred to as "100BASE-X." (The designation for "100BASE-T" is also sometimes seen as "100BaseT.")
