Question Discussion & Solution

Five students – M, Q, U, X, and Z are compared.

1. Weight of Z is less than only two students. _ > _ > Z > _ > _

2. Weight of Q is greater than Z and Weight of Q is less than only U.

U > Q > Z

From 1 and 2, we get:

U > Q > Z > M/X > M/X

The correct answer is Drag and Drop.

• The action of using the mouse to move an item on the computer screen to a new location is called Drag and Drop.
• Drag and drop is a common action performed within a graphical user interface that involves moving the cursor over an object, selecting it, and moving it to a new location.
• While using a mouse, we can drag and drop an object by clicking the mouse button to select an object, then moving the mouse while keeping the mouse button pushed down. This is called "dragging" the object.
• After moving the object where we want to place it, we can lift up the mouse button to "drop" the object in the new location. 
• Copy and paste are commands in a computer user interface and are one method of transferring data from one location to another. It creates a duplicate in the new location and enables simple data replication.
• Cut removes the item from its current location and places it into the clipboard. Paste inserts the current clipboard contents into the new location.
• Plug and Play is a phrase used to describe devices that work with a computer system as soon as they are connected.

Concept-

• When the functioning of one or more organs or systems of the body is adversely affected, characterized by various signs and symptoms, we say that we are not healthy, i.e., we have a disease.
• Diseases can be broadly grouped into infectious and non-infectious.
• Diseases that are easily transmitted from one person to another, are called infectious diseases.
• Infectious diseases are very common and every one of us suffers from these at some time or other. Some of the infectious diseases like AIDS are fatal.
• Non-infectious disease cancer is the major cause of death.

Important Points

• Hepatitis B is a liver disease that is caused by the hepatitis B virus (HBV).
• The virus is known to interfere with the functions of the liver and cause pathological damage.
• It can be both acute or chronic disease.
• HBV is spread by contact with the blood or body fluids of an infected person.

Explanation-

• Human beings have been abusing the water bodies around the world by disposing of them all kinds of waste.
• We tend to believe that water can wash away everything not taking cognizance of the fact that the water bodies are our lifeline as well as that of all other living organisms.
• Sewage from our homes as well as from hospitals is likely to contain many undesirable pathogenic microorganisms.
• Its disposal into the water without proper treatment may cause an outbreak of serious diseases, such as dysentery, typhoid, jaundice, cholera, etc.

Therefore Hepatitis-B is not a contaminated water disease.

Mistake Points

• Jaundice and Hepatitis B are not the same.
• Hepatitis B is a disease, while jaundice is a symptom.
• Jaundice symptom can be caused by many different reasons and Hepatitis B is just one of them. It can also be caused due to contaminated water.

Additional Information

Jaundice

• Jaundice can spread through contaminated water.
• It is a disease caused due to the accumulation of bilirubin in the blood and blood tissues.
• The disease causes yellowish discoloration of the skin, eyes, and other mucous membranes. 
• It is common in newborn babies because the newborn’s liver is not fully developed.
• Symptoms of Jaundice are fever, abdominal pain, weight loss, drowsiness, vomiting, etc.

Cholera

• Cholera is an acute diarrhoeal disease that can kill within hours if left untreated.
• It is caused due to the consumption of contaminated food or water.
• The provision of safe water and sanitation is critical to control the transmission of cholera and other waterborne diseases.
• It is caused by the bacterium Vibrio cholera.
• People may feel pain in their abdomen, nausea, vomiting, or watery Diarrhoea.
•  

The correct answer is Hard Disk.

• In a typical desktop computer,  Hard disk memory sizes would be the largest.
• had a capacity of 1 to 8 terabytes, with the largest-capacity drives reaching 20 terabytes (single-disk drives, "dual" drives are available up to 24 TB).
• Smaller, laptop internal 2.5-inch drives, are available up to 5 TB.
  • Register> RAM> Cache> Hard disk.

​​Key Points

• RAM 
  • RAM is a hardware element where the data being currently used is stored.
  • It is a volatile memory.
  • Two types of RAM are
    • Static RAM, or (SRAM) and
    • Dynamic RAM, or (DRAM).
• Register
  • A register holds instructions or data that the processor is working on or will be working on shortly.
  • They form part of the processor and are capable of holding only one item at a time.
• Cache 
  • Cache memory is an area in the computer where codes and instructions are stored.
• Hard disk
  • A hard disk drive is an electromechanical data storage device that stores and retrieves digital data using magnetic storage.

Additional Information

• There are four major storage levels on the computer:
  • Internal – 
    • Processor registers and cache.
  • Main –
    • The system RAM and controller cards.
  • On-line mass storage –
    • Secondary storage.
  • Off-line bulk storage –
    • Tertiary and Off-line storage.
