In computers, memory is considered as one of the most essential parts. It is the device that is used to store information in the computer for immediate use or later. It can also be considered as the brain of the computer. Computer memory is basically of two types, primary memory and secondary memory. Memory stores data inside itself for retrieval. Both primary and secondary memory have very different processes by which they save data.

Hunger vs Appetite   Our body has a beautiful clock hidden inside it that tells us from time to time that we are hungry and that we should eat something. Nobody tells us, and we do not even look at our watch but know that it is time for a snack, lunch, or dinner. However, do we eat because we are hungry or do we eat because of our appetite?

The key difference between purifier and clarifier is that the purifier consists of a dam ring to create a line of separation between fuel and water whereas the clarifier consists of a sealing ring to prevent the fuel tank from water and dissolved impurities. Purifier and clarifier are equipment that we use for cleaning or purification of fuel, mainly in case of ships and boats where it is common for fuel to get contaminated with water and other impurities.

Main Difference – Cilia vs Microvilli Cilia and microvilli are two types of projections in the plasma membrane. They can be found on the apical surface of some of the epithelial cells. Cilia are a component of eukaryotic cells. Microvilli are found on the surface of the intestinal villi and egg cells. Cilia are motile, but microvilli are non-motile.  The main difference between cilia and microvilli is that cilia are involved in the rhythmic movement of the cell or movement of objects over the cell surface whereas microvilli enhance the absorption of nutrients by increasing the surface area of the cell.

GPA has become a popular alternative to the percentage system for exams around the world. It stands for Grade Point Average. In some countries, the GPA is measured on a scale of 1-4, in others on a scale of 1-10. However, what people confuse as same is the Cumulative GPA and the Overall GPA. Cumulative GPA vs Overall GPAThe main difference between cumulative GPA and overall GPA is that cumulative GPA is the average of marks for each term examination that makes up a degree or course.

Men’s haircuts are relatively straightforward affairs. Barbers are trained in several techniques to cut hair according to the customer’s preference, and many of these techniques have become staples over time – particularly the fade and taper cuts, two terms which can confuse customers and barbers alike. How is a Fade different from a Taper? The main difference between a fade and a taper haircut concerns the way that hair changes in length as it goes down your hairline; a taper is a gradual shortening of hair from top to bottom, while the fade is a taper in which the hair is already short at the top, and is cut further so that the hair seems to “fade” into one’s hairline.

The main difference between Redis and Memcached is that Redis is an open source, key-value store that helps to build scalable web applications while Memcached is an open source, high performance distributed memory caching system that speeds up web applications by reducing the database loads. Big data refers to a collection of large data set. It has three properties as volume, variety and velocity. Volume refers to the amount of data while variety refers to various types of data and velocity refers to the speed of generating data.

Shooting Pain vs Radiating Pain Pain is a very excruciating experience for many people. In most cases, it is just a symptom of a bigger problem. Pain can have many types or classifications. It can vary from the mildest to the most agonizing form. It can also be either physical or emotional. On the physical aspect, there are certain types of pain that must be discerned. Two of which are the radiating pain and shooting pain.

“Throwable” is the parent class of the classes Error and Exception. The class “RuntimeException” and its subclasses, the class “Error” and its child classes are the “Unchecked exceptions” whereas, the remaining subclasses of the class “Exception” except “RuntimeException” are the checked exceptions. The basic difference between checked and unchecked exception is that the checked exceptions are checked by the compiler whereas, the compiler does not check the unchecked exceptions. Let us discuss the other differences between checked and unchecked exceptions with the help of the comparison chart.

Endpoint And Equivalence Point Titration measures the concentration of an unknown solution that reacts with a solution of known concentration. The process is often used to check the purity of synthesized chemical compounds such as pharmaceuticals. The ideal point for completion of titration is known as the equivalence point. The end point demonstrates the equivalence point, typically by some form of indicator. For example, with a color indicator, the solution changes color when the titration reaches the endpoint.
