UGC NET (NATIONAL ELIGIBILITY TEST) : OLD SOLVED/PREVIOUS EXAM QUESTION PAPERS WITH SOLUTIONS AND EXPLANATIONS AND FREE STUDY MATERIALS.
COMPUTER MEMORY BASED PREVIOUS YEARS SOLVED PAPERS I, II AND III TO PREPARE AND PASS THE UGC NET/SLET ENTRANCE EXAMINATION WITH HIGH PERCENTAGE.
COMPUTER BASIC QUESTIONS FOR BANK EXAM, HTAT, CTAT, TAT, UGC-NET, INTERVIEW AND OTHER EXAM'S, WHERE BASIC QUESTION'S ARE REQUIRED.
1. Manchester code is a ?
2. How many OSI layers are covered in the X.25 standard ?
3. The receive equalizer reduce delay distortions using ?
4. In communication satellite, multiple repeaters are known as ?
Explanation: A communications satellite's transponder, is the series of interconnected units which form a communications channel between the receiving and the transmitting antennas.
5. In OSI network architecture, the dialogue control and token management are responsibilities of ?
6. The geostationary satellite used for communication system ?
Explanation: A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period. Such a satellite returns to the same position in the sky after each sidereal day, and over the course of a day traces out a path in the sky that is typically some form of analemma. A special case of geosynchronous satellite is the geostationary satellite, which has a geostationary orbit – a circular geosynchronous orbit directly above the Earth's equator
7. Radio communication frequencies ranges from?
Explanation: Radio frequency (RF) is a rate of oscillation in the range of about 3 kHz to 300 GHz, which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals.
8. The frequency ranges from 300 KHz to 3 MHz is used for ?
9. Establishing a virtual connection is functionally equivalent to ?
10. Which of the following is a function of e-mail system ?
11. Which of the following is a congestion control algorithm?
The leaky bucket
Token bucket
Resource Respondez sil vous plait protocol
All of above
Answer = D
12. Which of the following is a function of e-mail system ?
13. Demodulation is the process of ?
14. Bulletin board system ?
15. An information utility can offer a user ?
16. A network that requires human intervention of route signals is called a ?
17. In OSI network architecture, the dialogue control and token management are responsibilities of ?
18. What is the main function of transport layer ?
19. Which of the following is an important characteristics of LAN ?
20. To deliver a message to the correct application program running on a host, the .... address must be consulted ?
