Q1: How many bits can be stored in the 8K RAM?

ANS:B - 8192

8K means 8 x 1024 bits = 8192 bits.

RAM size generally mentioned in bits.

Such as 4K X 8, 8K X 8, 4K X 16, 8K X 16 likewise...

For example 8K X 16, a RAM which has 8K = 8192 memory locations, with each location storing a data word of "width" 16 bits, would be referred to as a RAM of size 8K X 16. The total storage capacity of this memory would therefore be 128KB, or simply a "128K" memory.
