Biological computers use biological components like DNA to store and process data analogous to human body processes. They are implantable devices with a CPU and use DNA as software to monitor body activities and process data faster than traditional computers. DNA contains all genetic information in its molecular structure and biological computers use DNA computing, storing information in DNA molecules that can perform calculations much faster than regular computers using DNA's four basic components - adenine, cytosine, guanine and thymine. While biological computers are more efficient, accurate and environmentally friendly than traditional silicon-based computers, they also face challenges like potential hacking, need for human assistance, DNA degradation over time and rare pairing errors.

4. INTRODUCTION BIOLOGICAL COMPUTING
 Biological Computing means such a computing process like
traditional computers to use special biological components to
store and manipulate data analogous to processes in the
human body.
 They are not robots but they work like a powerful computer.
 It is like a doctor which can cure diagnosis of cancer and
Other diseases

5.  It is an implantable device that is mainly used for tasks like
monitoring of human body's activities
 It has CPU as its brain and DNA are its softwares
 It process faster computing process that operates with
accuracy.
Implantable Device

6.  DNA is what makes up your genes and stores all the
information about you inside your cells.
 It is a double, long chain of molecules that tell each cell what
proteins to make.
 DNA is made up of steps and rails of a ladder.
 Every living thing has DNA.

7. DNA in biological computer
 DNA computing is a branch of computing which uses DNA.
 A nano computer that uses DNA to store information and
perform complex calculations.
 DNA can perform calculations many times faster than the
world's most powerful human-built computers.
 It has a chip called biochip that will push computers even
faster.

8. HOW IT WORKS?
Biological computers are made inside a patient’s body.
 The information of the patient’s body is called a blueprint along
which lines the biological computer would be manufactured.
Through boolean logic equations, we can easily use the biological
computer to identify all types of activity and determine whether a
particular activity is harmful or not.

9. Specifications
One pound of DNA has the capability to store more information than all the
electronic computers ever made.
Would be more powerful than the worlds most powerful super computer.
Unlike binary computers, which work with just two states, On and Off (0 and
1), DNA computers will use the basic building blocks of life, strings of DNA,
molecules of type A (adenine) ,C (cytosine), G (guanine), and T (thymine)
,perform calculations at unimaginable speed.

11. SOMEFACTS
. This image shows 1 gram of DNA on a
CD. The CD can hold 800 MB of data.
 The 1 gram of DNA can hold about
1x1014 (100TB) MB of data

12. Comparison
Traditional computers
 Organic(DNA)
 Highly energy efficient
 Safe for environment
 Degrade over time
 Not as 100% accurate
 Inorganic(Silicon)
 Energy inefficient
 Harmful for environment
 Last for many years
 Almost perfect accuracy

13.  Cheaper
 Lightweight
 Performs millions of operations at same time.
 Diagnosis of cancer
 It has ability to solve hardest problems.
 Low power used
ADVANTAGES

14. DISADVANTAGES
• Hackers are able to wirelessly crack into the hardware installed in biological computer,
and control your body, sometimes forcing you to engage in unwanted behavior, such as
violence, financial suicide
• Human assistance is required.
• DNA has a half life.
• Sometimes there are errors in the pairing of DNA.
