1. Mesh is the smallest loop of circuit
2. Loop is smallest path of circuit

Assertion (A): In C arithmetic operations are pemiissible on ints, floats and chars.

Reason (R): In C every arithmetic operator must be written explicitly.

Assertion (A): Magnetic tape can be accessed only sequentially.

Reason (R): Magnetic tape consists of magnetised spots or tracks.

1. NAND
2. NOR
3. XOR

1. Multi-processing operation permits highly efficient parallel processing at several levels.
2. Multi processing involves use of several processing units jointly on a common program and severally on different programs.
3. In multi-processing the assignment of facilities to tasks, loading of programs and monitoring of I/O activity is taken care of by operating system.

Assertion (A): SSB transmitter is generally smaller than AM transmitter

Reason (R): SSB systems mostly use combined transmitter receiver.

Assertion (A): A Smith chart can be used for a number of calculations of a transmission line

Reason (R): Smith chart is basically a polar impedance diagram.
