How are radio waves used on Earth?

8 0

Uses of Radio Waves : The prime purpose of radio is to convey information from one place to another through the intervening media (i.e., air, space, nonconducting materials) without wires. Besides being used for transmitting sound and television signals, radio is used for the transmission of data in coded form.

BartSMP [9]

Answer:

a. Radom Access Memory (RAM).

Explanation:

If a computer user modifies a document that is saved on his or her computer. This changes are stored on the Radom Access Memory (RAM) until the computer user save the document.

Radom Access Memory (RAM) can be defined as the main memory of a computer system which allow users to store commands and data temporarily.

Generally, the Radom Access Memory (RAM) is a volatile memory and as such can only retain data temporarily.

All software applications temporarily stores and retrieves data from a Radom Access Memory (RAM) in computer, this is to ensure that informations are quickly accessible, therefore it supports read and write of files.

Determine the number of cache sets (S), tag bits (t), set index bits (s), and block offset bits (b) for a 1024-byte 4-way set as

Cerrena [4.2K]

Answer:

The answer is The Cache Sets (S) = 32, Tag bits (t)=24, Set index bits(s) = 5 and Block offset bits (b) = 3

Explanation:

Solution

Given Data:

Physical address = 32 bit (memory address)

Cache size = 1024 bytes

Block size = 8 bytes

Now

It is a 4 way set associative mapping, so the set size becomes 4 blocks.

Thus

Number of blocks = cache size/block size

=1024/8

=128

The number of blocks = 128

=2^7

The number of sets = No of blocks/set size

=128/4

= 32

Hence the number of sets = 32

←Block ←number→

Tag → Set number→Block offset

←32 bit→

Now, =

The block offset = Log₂ (block size)

=Log₂⁸ = Log₂^2^3 =3

Then

Set number pc nothing but set index number

Set number = Log₂ (sets) = log₂³² =5

The remaining bits are tag bits.

Thus

Tag bits = Memory -Address Bits- (Block offset bits + set number bits)

= 32 - (3+5)

=32-8

=24

So,

Tag bits = 24

Therefore

The Cache Sets = 32

Tag bits =24

Set index bits = 5

Block offset bits = 3

Note: ←32 bits→

Tag 24 → Set index 5→Block offset 3

Nuetrik [128]

Object-oriented databases is more flexible and stores data as well as instructions to manipulate the data.

A system known as an object database uses object-oriented programming to represent data in the form of objects. Different from relational databases, which are table-oriented, are object-oriented databases.

The concept of object-oriented programming languages, which is currently popular, is the foundation of the object-oriented data model. Overloading, polymorphism, and inheritance Object-oriented programming fundamentals that have found use in data modelling include object-identity, encapsulation, and information hiding with methods to provide an interface to objects. The rich type system, which includes collection and structured types, is supported by the object-oriented data model as well.

In contrast to relational databases, which can only handle one type of data, object databases can handle multiple data types. Unlike conventional databases like hierarchical, network, or relational, object-oriented databases can handle a variety of data types, including text, numbers, images, voice, and video.

Also, Reusable code, realistic modelling, and increased dependability and flexibility are all provided by object-oriented databases.
