Question

Each entry in a Translation look-aside buffer (TLB) consists of :

a) Key
b) Value
c) Bit value
d) Constant

Answer 1

Each TLB entry consists of a key and a value, where the key includes a tag representing part of an address, and the value contains the physical address or frame number and additional control bits.

Step-by-step explanation:

Each entry in a Translation look-aside buffer (TLB) primarily consists of two parts: a key and a value. The key is generally made up of a tag which represents part of the address information used to determine whether the corresponding translation is in the TLB often corresponding to the virtual address being accessed.

The value contains the physical address or the frame number along with other relevant status or control bits such as valid and modified information. Additionally each TLB entry typically includes a value known as the Access Control Information which includes bits for permissions like read/write access.
