The telephone system is an example of a ________ network.
circuit-switched
In TCP/IP, IP is responsible for:
disassembling and reassembling of packets during transmission.
The method of slicing digital messages into parcels, transmitting them along different communication paths, and reassembling them at their destinations is called:
packet switching
The device that acts as a connection point between computers and can filter and forward data to a specified destination is called an:
SWITCH
Which signal types are represented by a continuous waveform?
Analog
What are the four layers of the TCP/IP reference model?
Application, transport, Internet, and network interface
The Internet is based on which three key technologies?
Client/server computing, packet switching, and the development of communications standards for linking networks and computers
A hub is a networking device that connects network components and is used to filter and forward data to specified destinations on the network.
FALSE
An NOS must reside on a dedicated server computer in order to manage a network.
FALSE
Central large mainframe computing has largely replaced client/server computing.
FALSE
Circuit switching makes much more efficient use of the communications capacity of a network than does packet switching.
FALSE
Mobile search makes up approximately 10% of all Internet searches.
FALSE
RFID technology is being gradually replaced by less costly technologies such as WSNs.
FALSE
TCP/IP was developed in the 1960s to enable university scientists to transmit data from computer to computer.
FALSE
The number of cycles per second that can be sent through any telecommunications medium is measured in kilobytes.
FALSE
Which of the following is not a characteristic of packet switching?
Packet switching requires point-to-point circuits.
Coaxial cable is similar to that used for cable television and consists of thickly insulated copper wire.
TRUE
Fiber-optic cable is more expensive and harder to install than wire media.
TRUE
In a client/server network, a network server provides every connected client with an address so it can be found by others on the network.
TRUE
In a large company today, you will often find an infrastructure that includes hundreds of small LANs linked to each other as well as to corporate-wide networks.
TRUE
In blogging, a trackback is a list of entries in other blogs that refer to a post in the first blog.
TRUE
Increasingly, voice, video, and data communications are all based on Internet technology.
TRUE
Telephone networks are fundamentally different from computer networks.
TRUE
The Domain Name System converts domain names to IP addresses.
TRUE
To create a computer network, you must have at least two computers.
TRUE
Two computers using TCP/IP can communicate even if they are based on different hardware and software platforms.
TRUE
VoIP technology delivers voice information in digital form using packet switching.
TRUE
Web 3.0 is a collaborative effort to add a layer of meaning to the existing Web in order to reduce the amount of human involvement in searching for and processing Web information.
TRUE
To use the analog telephone system for sending digital data, you must also use:
a modem
In a telecommunications network architecture, a protocol is:
a standard set of rules and procedures for control of communications in a network.
