Sample Distributed Systems Important questions:

1. Define distributed systems?

A distributed system is a collection of independent computers that appears to its users as a single coherent system.
(Or)
A distributed system is one in which components located at networked computers communicate and coordinate their actions only by passing messages. This  definition leads to the following

characteristics of distributed systems:
 Concurrency of components
 Lack of a global ‘clock’
 Independent failures of components

2. Give examples of distributed systems.

 Intranet and Local Area Network
 Internet/World-Wide Web
 Mobile and Ubiquitous Computing
 Database Management System
 Automatic Teller Machine Network
 E-mail
 Newsgroups and bulletin boards
 FTP, Telnet
 W WW
 Distributed computing
 Electronic payment
 Distributed real-time processing

3. Write the following

(i)HTTP (ii) HTML (iii) URL
The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems.[1] HTTP is the foundation of data communication for the Web. Hypertext is structured text that uses logical links (hyperlinks) between nodes containing text. HTTP is the protocol to exchange or transfer hypertext.

(ii) HTML is the standard markup language used to create web pages.[1]Web browsers can read HTML files and render them into visible or audible web pages. HTML describes the structure of a website semantically along with cues for presentation, making it a markup language, rather than a programming language

(iii) URL is an acronym for Uniform Resource Locator and is a reference (an address) to a resource on the Internet. A URL has two main components:

A distributed system is a software system in which components located on networked computers communicate and coordinate their actions by passing messages.

The components interact with each other in order to achieve a common goal.

Distributed systems Principles

A distributed system consists of a collection of autonomous computers, connected through a network and distribution middleware, which enables computers to coordinate their
activities and to share the resources of the system, so that users perceive the system as a single, integrated computing facility.
Centralised System Characteristics
 One component with non-autonomous parts
 Component shared by users all the time
 All resources accessible
 Software runs in a single process
 Single Point of control
 Single Point of failure

Sample Antenna and Wave propagation Important questions:

1.Define Sky wave.
Waves that arrive at the receiver after reflection in the ionosphere is called sky wave.

2.Define Tropospheric wave.
Waves that arrive at the receiver after reflection from the troposphere region is called
Tropospheric wave.(ie 10 Km from Earth surface).

3.Define Ground wave.
Waves propagated over other paths near the earth surface is called ground wave propagation.

4.What are the type of Ground wave.
Ground wave classified into two types.

i. Space wave
ii. Surface wave.

5. What is meant by Space Wave?
It is made up of direct wave and ground reflected wave. Also includes the portion of energy received as a result of diffraction around the earth surface and the reflection from the upper
atmosphere.

6. What is meant by Surface Wave?
 Wave that is guided along the earth‘ s surface like an EM wave is guided by a
transmission is called surface wave. Attenuation of this wave is directly affected by the
constant of earth along which it travels.

7. What is meant by fading?
Variation of signal strength occur on line of sight paths as a result of the atmospheric
conditions and it is called .It can not be predicted properly.

8. What are the type of fading?
Two types. i. Inverse bending.
