MIS 111 PAR 21 - Network Infrastructure & Ch. 6.1 - 6.2 (What is a Computer Network; Network Fundamentals)

_______________ refers to the transmission capacity of a network; it is stated in bits per second.

Bandwidth

__________________ links two or more computers in an arrangement in which some machines, called _________, provide computing services for user PCs, called _________.

Client/server computing; servers; clients

What does DSL stand for?

Digital Subscriber Line

_______________ divides processing work among two or more computers.

Distributed processing

According to IT's About Business 6.1, __________ is the world's most isolated country when it comes to telecommunications access.

Eritrea

________________ have large storage and processing power and therefore can run local programs (such as Microsoft Office) if the network goes down.

Fat clients

What does FCC stand for?

Federal Communications Commission

____________ is a cable medium.

Fiber-optic

_____________ is an advantage of coaxial cable.

High bandwidth

______________________ defines how messages are formulated and how they are interpreted by their receivers.

Hypertext Transfer Protocol (HTTP)

The ____________________ is responsible for addressing, routing, and packaging data packets. The IP is one of the protocols in this layer.

Internet layer

What does LAN stand for? Define LAN.

Local Area Network; LAN connects two or more devices in a limited geographical region, usually within the same building, so that every device on the network can communicate with every other device.

What does MAN stand for? Define MAN.

Metropolitan Area Network; MAN are relatively large computer networks that cover a metropolitan area.

From smallest to largest, which of the following is in the correct order of networks?

PAN, LAN, MAN, WAN

____________________ is a type of client/server distributed processing in which each computer acts as both a client and a server

Peer-to-peer (P2P) processing

What does PAN stand for? Define PAN.

Personal Area Network; PAN are short-range networks -typically a few meters- that are used for communication among devices close to one person.

With ________, decisions controlling how network traffic flows across network devices are managed centrally by software.

SDN

________________________________ are an emerging technology that is becoming increasingly important to help organizations manage their data flows across their enterprise networks.

Software-Defined Networks (SDN)

________________ may have no local storage and only limited processing power.

Thin clients

________________________________ is the protocol of the Internet.

Transmission Control Protocol/Internet Protocol (TCP/IP)

The Internet is a _______________.

Wide Area Network (WAN)

What does WAN stand for? Define WAN.

Wide Area Networks; WAN is a network that covers a large geographical area. WANs typically connect multiple LANs.

Corporate ______________ are high-speed central networks to which multiple smaller networks (such as LANs and smaller WANs) connect. The LANs are called _____________ because they connect to the backbone WAN.

backbone networks; embedded LANs

The Federal Communications Commission's (FCC) new rules define ____________ as the transmission capacity of a communications medium (discussed later in this chapter) faster than 25 megabits per second (Mbps) for download (transmission speed for material coming to you from an Internet server, such as a movie streamed from Netflix) and 4 Mbps for upload (transmission speed for material that you upload to an Internet server such as a Facebook post or YouTube video).

broadband

Communicating data from one location to another requires some form of pathway or medium. A __________________ is such a pathway.

communications channel

Organizations today have multiple LANs and may have multiple WANs. All of these networks are interconnected to form an ________________.

enterprise network

Bandwidth ranges from ____________ (relatively low transmission capacity) to _____________ (relatively high network capacity).

narrowband; broadband

The _______________________ places packets on, and receives them from, the network medium, which can be any networking technology.

network interface layer

The transmission technology that breaks up blocks of text into packets is called _____________.

packet switching

The ___________________ provides the application layer with communication and packet services. This layer includes TCP and other protocols.

transport layer
