1.
Which
characteristics of a multiterminal system make it
different from a computer network?
A processing power of multiterminal
systems remained
fully centralized, while computer networks have a distributed processing power.
2.
When were
the first important results achieved in the field of joining computers using
long-haul links?
In the late 60s
3.
What is
ARPANET?
A.
A network of supercomputers
belonging to military organizations and research institutes in the
B. An international scientific research network
C. The technology of creating WANs
A is correct
4.
When did
the first network operating systems appear?
In the late 60s
5.
In what
order did the events listed here take place?
A. The invention of Web
B. The development of standard LAN technologies
C. The start of voice transmission in digital form through telephone networks
The invention of World Wide Web
6.
Which of
the events stimulated LAN development?
Appearance of large-scale integrated circuits (LSI devices) resulted
in invention of microcomputers which in its turn stimulated a research activity
in the area of local computer networks (LANs). The adoption of personal
computers was a powerful incentive for the development of LANs.
7.
Specify
when the following technologies were standardized: Ethernet, Token Ring, and
FDDI.
1980, 1985 and 1985 respectively
8.
List the
main directions in which the convergence of computer and telecommunications
networks proceeds.
First, convergence of service types provided to the clients is to be
noticed. For example, modern computer networks support voice transmission that
previously was a prerogative of telephone networks. Convergence of technologies
is another direction of the process. A transmission of various kinds of
information such as data, voice and video in a common digital form gives us an
example of a converged technology.
9.
Explain
the meaning of the following terms: multiservice
network, info-communications network, and Intelligent Network.
Multiservice network is a universal network capable to provide a rich set
of services combining telephony and
data services; for example, providing a unified messaging service which
combines e-mail, voice, fax and paging services.
Infocommunications networks are a result of a deep mutual penetration of two major components of
contemporary networks. These are informational (computer-based) and
telecommunications components.
Intelligent Network (IN) are supplementary services provided by
telephone networks, such as call transfer, conferencing, and telepolling, which are implemented by means of a supplementary computer
network with servers in which the service logic is programmed.
These three terms are very close and can be used
as synonyms.
1.
Explain
why WANs appeared earlier than LANs.
2.
Using
various sources on the Internet, find historical relationships between the X.25
technology and the ARPANET network.
3.
Do you
think that the history of computer networks can be interpreted as the history
of the Internet evolution? Substantiate your opinion.
