1. Out of four devices mentioned below, the fastest switching device is
- JFET
- BJT
- MOSFET
- Triode
2. IP address assigned to a computer which uses TCP/IP protocol consists of
- 4 bits
- 8 bits
- 16 bits
- 32 bits
3. In RS 232 standard, the capacitance of the transmission line normally employed is
- 300nF – 1200nF
- 1200nF – 2400nF
- 300pF – 1200pF
- 1200pF – 2400pF
4. Power amplification is biggest in
- CE configuration
- CB configuration
- CC configuration
- BE configuration
5. Norton’s theorem converts a complicated electric network into
- a simple circuit with a voltage source with a series internal resistance
- in ideal voltage source
- an ideal current source
- an current source with a shunt resistance
6. For a microampere meter to work as an ammeter, one should
- connect a shunt and calibrate it
- connect a high resistance in series and calibrate it
- connect a high resistance as well as shunt and calibrate it
- just connect it in series
7. Email is used to
- send letter only
- receive letter only
- send and receive letter
- none of the above
8. For a given rate voltage and drain voltage less than ‘Pinch-off’ voltage, the field effect transistor operates as
- a voltage variable resistor
- constant current device
- signal amplifier
- none of the above
9. The advantage of RISC processor over CISC processor is that
- The hardware architecture is simpler
- as instruction can be executed in one cycle
- less number of registers accomodate in chip
- parallel execution capabilities
10. In packet switching network, packets move with
- source identity
- destination identity
- message and packet identity
- all of them
11. The function of modulator is
- separate two frequencies
- extract information from the carrier
- amplify the audio frequency signal
- impresses the information a RF carrier
12. The evolution of CDMA 2001X will be implemented in steps: 1X EVDO and 1XEVDV, where “1XEV-DV” stands for 1xEvolution ….
- data and voice
- digital video
- data and video
- none of the above
