World Consumer Rights Day is being observed globally on 15 March which is an awareness day for the consumers.

Hard disk is the secondary storage device, which holds the data in bulk, and it holds the data on the magnetic medium of the disk.Hard disks have a hard platter that holds the magnetic medium, the magnetic medium can be easily erased and rewritten, and a typical desktop machine will have a hard disk with a capacity of between 10 and 40 gigabytes. Data is stored onto the disk in the form of files.

Resistivity :

Resistivity is a measure of the resistance to the flow of electrons. 

Conductivity :

Conductivity is just the inverse of resistivity, σ = 1/ρ, where σ is conductivity and ρ is resistivity.

Example:

Think of a pipe and water, the bigger the pipe, the easier water can flow and thus the lower the resistance. 

Self pollination occurs in the flowers when the pollen grains of the flower falls on the stigma of the same due to wind or insects like moths and bees. This lead to the inbreeding.

Shillong is the capital city of Meghalaya state in India. It is well known tourist place as a hill station in northeast India which attracts tourists all over the world.

Dr. B. R. Ambedkar attended all the three-round table conferences.

The resistivity of wire or the metal conductor is depend on the number density of free electrons in the conductor. so its mainly depends on nature of the material
