10 important and commonly asked questions from past BCom Computer exams, along with their answers:

Part 1: Basic Computer Concepts

1. Explain the difference between hardware and software.

Answer:

 Hardware refers to the physical components of a computer, such as the monitor, keyboard, and motherboard. Software refers to the programs and applications that run on a computer, such as operating systems, word processors, and games.

2. What are the primary functions of an operating system?

 Answer:

The primary functions of an operating system include managing hardware resources, providing a user interface, executing and providing services for applications, and ensuring security and access control.

3. Define 'bit' and 'byte'.

 Answer:

A bit (binary digit) is the smallest unit of data in a computer, representing a single binary value (0 or 1). A byte is a unit of digital information that consists of 8 bits.

4. What is the purpose of RAM in a computer system?

Answer:

 RAM (Random Access Memory) is used to store data and instructions temporarily while a computer is running. It allows for quick read and write access to a storage medium that is much faster than a hard drive or SSD.

5. Differentiate between system software and application software.

 Answer:

 System software includes the operating system and all utilities that enable the computer to function. Application software includes programs that perform specific tasks for users, such as word processors, spreadsheets, and database management systems.

 

 

 

Part 2: Advanced Computer Concepts

6. Explain the concept of 'database normalization'.

Answer:

Database normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. It involves dividing a database into two or more tables and defining relationships between the tables.

7. What is a computer network, and what are its types?

Answer:

A computer network is a set of computers connected together for the purpose of sharing resources. The types of computer networks include LAN (Local Area Network), WAN (Wide Area Network), MAN (Metropolitan Area Network), and PAN (Personal Area Network).

8. What is cloud computing?

Answer:

 Cloud computing is the delivery of computing services over the internet. These services include storage, databases, servers, networking, software, and more, providing flexible resources and economies of scale.

9. What are the differences between static and dynamic web pages?

Answer:

Static web pages are fixed and display the same content to every user. They are usually written in HTML and do not change unless manually updated. Dynamic web pages, on the other hand, are generated in real-time based on user interactions or other parameters, often involving server-side scripts like PHP or ASP.NET.

10. Explain the concept of 'Internet of Things' (IoT).

Answer:

 The Internet of Things (IoT) refers to the network of physical objects embedded with sensors, software, and other technologies to connect and exchange data with other devices and systems over the internet. This enables these objects to collect and share data, improving efficiency and creating new applications and services.

 

What Are Menstrual Problems?

Menstrual Problems

Menstrual cycles often bring about a variety of uncomfortable symptoms leading up to your period. Premenstrual syndrome (PMS) encompasses the most common issues, such as mild cramping and fatigue, but the symptoms usually go away when your period begins.

However, other, more serious menstrual problems may also occur. Menstruation that is too heavy or too light, or the complete absence of a cycle, may suggest that there are other issues that are contributing to an abnormal menstrual cycle.

Remember that a “normal” menstrual cycle means something different for every woman. A cycle that’s regular for you may be abnormal for someone else. It’s important to stay in tune with your body and to talk to your doctor if you notice any significant changes to your menstrual cycle.

There are several different menstrual problems that you may experience.

Premenstrual Syndrome

PMS occurs one to two weeks before your period begins. Some women experience a range of physical and emotional symptoms. Others experience few symptoms or even none at all. PMS can cause:

• bloating
• irritability
• backaches
• headaches
• breast soreness
• acne
• food cravings
• excessive fatigue
• depression
• anxiety
• feelings of stress
• insomnia
• constipation
• diarrhea
• mild stomach cramps

You may experience different symptoms every month, and the severity of these symptoms can also vary. PMS is uncomfortable, but it’s generally not worrisome unless it interferes with your normal activities.

Heavy Periods

Another common menstrual problem is a heavy period. Also called menorrhagia, heavy periods cause you to bleed more than normal. You may also have your period for longer than the average of five to seven days.

Menorrhagia is mostly caused by imbalances in hormone levels, especially progesterone and estrogen.

Other causes of heavy or irregular menstrual bleeding include:

• puberty 
• vaginal infections
• inflammation of the cervix
• underactive thyroid gland (hypothyroidism)
• noncancerous uterus tumors (fibroids)
• changes in diet or exercise

Absent Periods

In some cases, women may not get their period. This is called amenorrhea. Primary amenorrhea is when you don’t get your first period by age 16. This may be caused by an issue with the pituitary gland, a congenital defect of the female reproductive system, or a delay in puberty. Secondary amenorrhea occurs when you stop getting your regular periods for six months or more.

Common causes of primary amenorrhea and secondary amenorrhea in teens include:

• anorexia
• overactive thyroid gland (hyperthyroidism)
• ovarian cysts
• sudden weight gain or loss
• stopping birth control
• pregnancy

When adults do not menstruate, the common causes are often different. These may include:

• premature ovarian failure
• pelvic inflammatory disease (a reproductive infection)
• stopping birth control
• pregnancy
• breastfeeding
• menopause

A missed period could mean that you’re pregnant. If you suspect you may be pregnant, be sure to take a pregnancy test. Drugstore pregnancy tests are the least expensive way to determine whether or not you are pregnant. To get the most accurate results, wait until you have missed your period by at least one day before taking the test.

Painful Periods

Not only can your period be lighter or heavier than normal, but it can also be painful. Cramps are normal during PMS and they also occur when your uterus contracts as your period begins. However, some women experience excruciating pain. Also called dysmenorrhea, extremely painful menstruation is likely linked to an underlying medical problem, such as:

• fibroids
• pelvic inflammatory disease
• abnormal tissue growth outside of the uterus (endometriosis)

Diagnosing Menstrual Problems

The first step in diagnosing menstrual problems is to see your doctor. Your doctor will want to know about your symptoms and for how long you’ve been experiencing them. It may help to come prepared with notes on your menstrual cycle, how regular it is, and any symptoms you have been experiencing. Your doctor can use these notes to help figure out what is abnormal.

In addition to a physical exam, your doctor will likely do a pelvic exam. A pelvic exam allows your doctor to assess your reproductive organs and to determine if your vagina or cervix is inflamed. A Pap smear will also be performed to rule out the possibility of cancer or other underlying conditions.

Blood tests can help determine whether hormonal imbalances are causing your menstrual problems. If you suspect that you may be pregnant, your doctor or nurse practitioner will order a blood or urine pregnancy test during your visit.

Other tests your doctor may use to help diagnose the source of your menstrual problems include:

• endometrial biopsy (used to extract a sample of your uterine lining that can be sent for further analysis)
• hysteroscopy (a small camera is inserted into your uterus to help your doctor find any abnormalities)
• ultrasound (used to produce a picture of your uterus)

Treating Menstrual Problems

The type of treatment will depend on what’s causing the problems with your menstrual cycle. Birth control pills can relieve symptoms of PMS, as well as regulate heavy flows. If a heavier or lighter than normal flow is related to a thyroid or other hormonal disorder, you may experience more regularity once you start hormone replacements.

Dysmenorrhea may be hormone related, but you may also require further medical treatment to address the problem. For example, antibiotics are used to treat pelvic inflammatory disease.

Long-Term Outlook

Irregularities between periods are normal, so the occasional light or heavy flow is generally not something to worry about. However, if you experience severe pain or a heavy flow with blood clots, you should call your doctor right away. It’s is also recommended that you get medical attention if your periods occur less than 21 days apart, or if they happen more than 35 days apart.

Seven Tips For A Long And Healthy Life.

As good as modern medical technology is, it can never save you from the problems caused by an unhealthy lifestyle. Instead of having a modern medical solution for every problem, it is much better to live so that you hardly ever get sick.

 

An ounce of prevention is certainly better than a pound of cure. Here are seven tips to live a long and healthy life. The same lifestyle that helps you avoid disease also helps you lose weight.

 

1. Enough movement

In the past, people had to use their physical bodies in their normal work. But today it may happen that someone gets up, goes to work in the car, then sits down, gets up to go home in the car, and then sits down again for the rest of the day when he gets home. There is no physical labor in such a life. This physical inactivity is one of the main causes of many diseases. Sports, running. walking and other things must be added to our life if our normal work does not require physical exertion. I

 

2. Go to bed when you feel sleepy

It may sound simple, but many people stay awake even when their bodies tell them it's time to sleep. Yoga and Ayurvedic doctors also say that it is better to sleep at night and be active during the day. However, people like students will take coffee and stimulants to study late into the night. Others develop a habit of staying active at night and sleeping during the day. Even if we can do it, it eventually takes a toll on our health. Alternative health practitioners say that this kind of unnatural life is one of the contributing factors to cancer and other diseases.

 

3. Eat when you're hungry

 

This is also a simple idea, but again, we often go against the body's messages. If you eat out of habit or because of social pressure at a certain time of the day, even when you have no real appetite, then you will not digest your food properly. Acidity and indigestion begin, which contributes to the likelihood of other, more complex diseases taking root. Appetite is actually a sign of good health, but if you don't have an appetite, you should wait a while before eating. (If you have no appetite after a reasonable amount of time, you should consult a doctor because something is wrong.)

4. Fasting on a regular, systematic basis

 

If you asked someone to work 365 days a year without rest, they would complain and say that they have to have some rest or they will collapse. But we never bothered to ask or think about our digestive organs, which we force to work day after day without rest. They can't protest like a person to their boss, but they give us signals that they can't work around the clock. When we ignore these signals and keep forcing them to work, these organs break down. Therefore, regular fasting is necessary. Don't eat for one whole day. This gives rest to your digestive organs and also helps in removing waste from your body. Regular fasting allows one to gain extra time for intellectual or spiritual pursuits. Fasting is not for hermits in a cave, but it is a sensible practice that anyone can practice.

 

5. Wash with cold water before going to bed

 

As mentioned above, proper sleep is essential for maintaining health. If you wash your important motor and sensory organs (hands, arms, eyes, feet, mouth, genitals) with cold water before going to bed, you will relax and prepare for deep sleep.

 

6. Meditate regularly

 

Your body is connected to your mind. Many diseases of this time are psychosomatic. Stress and anxiety take their toll on our physical health. Meditation is a mental exercise that, among other things, allows you to detach from the worries of life. Learn a simple technique and do it regularly.

 

7. Get up early every day

 

Again, the old saying applies: "Early to bed, early to rise is healthy, rich and wise." I don't know if it will make you rich, but it will certainly make you healthy. Your body needs just the right amount of sleep, neither too much nor too little. 

How to adopt good habits?

                                      STOP BAD HABITS

Each person has at the least one terrible dependency that they would really like to eliminate. But it's far difficult – and the problem is going past self-discipline. Like effective conduct, which include mechanically memorizing and following a path, terrible conduct are fashioned from exercise and repetition. To take away them, you want to observe this equal process. 

This is what Elliot Beckman, director of the Social and Affective Neuroscience Laboratory at the University of Oregon, and Russell Pollack, a professor of psychology at Stanford University, give an explanation for in an interview with Time magazine. Experts suggest 5 techniques that observe the common sense of technological know-how and may assist with re-education. Lower your pressure levels In addition to being bolstered via way of means of non-stop exercise, much terrible conduct, are inspired via way of means of physiological factors.

Some examples are cigarettes, sugar and chemical narcotics. Its intake is related to dopamine, a praise device with inside the mind that impacts connections among neurons and the mind structures liable for actions. The frame's response to this kind of substance refers back to the evolution of the human species, in line with Pollack.

He explains that our frame isn't geared up to address its stimuli and that, as a result, our mind can end up overloaded. Once pressure Sleeping greater, workout often and adopting rest techniques, which include meditation, are among a number of the answers talked about via way of means of the professor to boom self-discipline and mind health.

Easy conduct to domesticate first factor with inside the morning and create the appropriate ordinary know your cues According to Beckman, conduct contain 3 parts: cues, ordinary and praise. Cues are characterized via way of means of contexts that stimulate the dependency, appearing as a trigger – like on foot right into a bar, even as seeking to prevent drinking. To stay clear of this factor, stopping them from occurring is the first-class manner. It's really well worth developing new conduct. Looking for large changes, which include converting jobs or cities, also can assist, as they create the possibility to construct new conduct from scratch.

Replace a terrible dependency with a terrific one, studies display that the greater we suppress a thought, the greater we generally tend to consider it. Beckman makes use of cigarettes as an example: If you're a smoker, and also you inform your self now no longer to smoke, your mind nonetheless hears “smoking.” So a terrific manner out is to create a brand-new dependency to update the antique one, instead of simply repress it is viable to change cigarettes for gum and alcohol for water, for example, however maintain in thoughts that it may take time to adapt. Have a higher purpose to go away him while changing the undesirable dependency with a brand-new you may assist in ordinary existence, it may not always make our frame neglect about easily. The mind registers that gum isn't the equal factor as nicotine, and it may not produce the equal sensation easily. Therefore, in line with Beckman, it's far crucial to hold a more potent motivation to allow move of that addiction. It's really well worth bearing in thoughts, for example, that giving up smoking can carry greater years of existence throughout the own circle of relatives or that ingesting fewer hamburgers will carry greater power to sports you enjoy.

Set higher goals According to Pollack, greater than putting an aim of now no longer doing something, it's far important to devise the way to put in force this aim with inside the ordinary. This consists of making a plan of actions – which include fending off going thru the cookie shelf in case you need to prevent shopping for them. The professor additionally explains that considering how precisely you'll place some-thing into exercise can assist to increase the attitude that you could do it – that is already 1/2 of the battle.

The Internal Clitoris, or That Thing You Never Knew You Had That.

The Internal Clitoris, or That Thing You Never Knew You Had. 

STOCKSY, THE CENTER FOR EROTIC INTELLIGENCE/MAL HARRISON

It’s surprising that, even in 2017, there’s still so much about women’s anatomy that we’re not talking about. For example, most of us probably don’t know that there’s more to our clitoris than that little rosebud-shaped knob at the apex of our labia. But in reality that little love button is only the tip of a surprisingly complex iceberg called the internal clitoris.

The internal clitoris was the hot topic at a recent Future of Sex live panel, a gathering of the sex industry’s most brilliant minds to discuss sexuality, vaginas, and women’s pleasure. Those minds included Alex Fine, cofounder of Dame Products, Polly Rodriguez, founder of Unbound, and Mal Harrison, director of the Center for Erotic Intelligence (formerly Ms. M, advice giver over at the Museum of Sex’s website). These women are basically the experts on everything clit science—and yes, clit science is totally a thing.

So what are all the things the mysterious internal clitoris do? Here's some of the most important stuff to know about this amazing organ:

The internal clitoris is way bigger than you'd think.

Let’s get biological! The clitoris as a whole is composed of an external circular mass of glans, with bulbous internal extensions (called the vestibular bulbs) and internal winglike extensions (called the corpus cavernosum).

In a sonogram picture it looks a bit like an eagle in flight, descending upon its prey. “The clitoris continues on inside of the body, allowing for clitoral stimulation via the vaginal wall and other parts of the vulva,” Alex Fine explained. The external part of the clitoris is probably the part you're most familiar with (and if you’re not, you better go find it ASAP).

The clitoris contains more than 8,000 nerve endings, and is made up of the same erectile tissue as the penis—it even fills with blood and becomes engorged when we’re aroused, just like a how a dude’s junk does. In a lot of ways, it really is the female equivalent of the penis, but we don’t need to call it that because women deserve control and agency over their bodies.

But it’s not just the part of the clit we can see that reacts when you’re aroused. According to Rebecca Brightman, M.D., an ob-gyn at East Side Women’s Associates, the entire clitoris is “0.5 to 2 cm in length, and the glans is less than 1 cm. The entire clitoral complex—including the internal wings—will become engorged and enlarged with stimulation.”

COURTESY OF SHE KNOWS

Not a lot was understood about the clitoris until surprisingly recently.

Most of our info about the clit comes from research done in the nineties. No, not the 1890s: The medical community was still largely uninterested in female pleasure until 20 years ago.

Harrison tells Glamour that the medical community didn’t know about the clitoris’ identical makeup to the penis until—surprise, surprise—a female urologist named Helen O’Connell, M.D., figured it out while dissecting cadavers. She published her work, “The Anatomy of the Clitoris,” in 1998.

Though most women probably knew that their lady bits were a source of pleasure long before science caught up, doctors and scientists believed the clit was a rather straightforward piece of anatomy. The assumption was that the clitoris was comprised entirely of a small exterior bundle, with nothing to see below. It wasn’t until MRAs were done of the clitoris that its deeper, internal structure was finally revealed. Not only that, but “the first 3-D sonography of the clitoris happened in 2008,” says Fine. Scientists Buisson and Foldès were two of the leading researchers in uncovering its full structure, using sonograms to document its movement, sensitivity, and what it looked like.

All orgasms are technically clitoral orgasms.

Yup, even G-spot orgasms (the G-spot is actually the spot closest to the root of the clit).

Of course, there’s much more to the female orgasm than the clitoris, or even the vagina for that matter. Female pleasure is derived from a variety of pleasure points; clusters of muscles and nerves on various erogenous zones, such as the nipples, ears, and thighs. Women’s bodies are complex, with a vast number of pleasurable pathways to explore.

Still, the clitoris may exist for more than just sexy times. The clitoris, says Dr. Brightman, “plays a role in sexual response: During ovulation women have an increased sex drive and libido. Positive sexual experiences foster procreation. So, indirectly, the clitoris plays another role than just pleasure.” After all, if we don’t enjoy sex, how can we be expected to have it and make babies?

When it comes to women’s bodies, it’s safe to say the clit is queen—even if there’s still probably a lot more to know about the clitoris, pleasure, and sexuality as a whole.

WHAT IS SEX LUBES OR VAGINAL LUBES ?

             "BATTER SEX KA RAAZ OR MAZA"

VAGINAL LUBES

The vagina naturally produces lubrication that helps facilitate sexual activity. If natural lubrication is not enough, people can use artificial lubricant, or lube, to make sexual activity more comfortable.

When a person becomes sexually aroused, their vagina produces extra lubrication. This lubrication reduces friction in the vagina, increasing comfort during sex and minimizing any feelings of soreness or irritation. However, vaginal dryness is a very common sexual issue.

Artificial lubricants reduce vaginal dryness. Lubes are available in many different textures, flavors, and materials to suit a person’s needs and preferences.

In this article, we explain natural vaginal lubrication and discuss the types, benefits, and possible side effects of artificial lubrication.

What is natural vaginal lubrication?

Natural vaginal lubrication may occur when a person is experiencing arousal.

Vaginal tissue is naturally moist.

Fluid from the cervix and secretions from the Bartholin glands — two pea sized glands at the entrance to the vagina — help keep the vagina lubricated. During arousal, the Bartholin glands secrete extra fluid to reduce friction.

Occasional vaginal dryness is common, but chronic vaginal dryness can signal either menopause or a medical issue, such as vaginal atrophy. People who routinely struggle with vaginal dryness should talk to a healthcare professional.

As a person ages, the tissue of the vagina thinsTrusted Source. During and after menopause, the body produces less estrogen, which leads to fewer moisturizing secretions and can make the vagina feel dry.

Once the vaginal tissues become thinner, the individual may need more lubrication than they previously did to feel comfortable during sexual activity.

When to use lubricant

It is common, even among healthy people, for the vagina to produce insufficient lubrication. Artificial lubricant replaces the natural vaginal secretions, making the vagina feel more moist and reducing any discomfort resulting from vaginal dryness.

A person might choose to use synthetic lubricant when:

• they experience vaginal dryness due to medication
• changes in hormone levels during pregnancy or after childbirth cause temporary vaginal dryness
• menopause causes vaginal dryness
• their vagina does not produce sufficient lubrication — for example, if they “run out” of lubrication after a long session of sexual activity or find that their natural lubricant is insufficient to reduce the friction of sex
• they experience pain or itching in their vagina, which can happen when sensitive vaginal tissue is very dry 

Types of lubricant

A person who wants to try artificial lubricant has several options, including those below:

Vaginal lubricants

There are a number of vaginal lubricants available in pharmacies and online.

Drugstores stock dozens of vaginal lubricants, which come in different flavors depending on a person’s preference.

These products provide short term moisture for various forms of vaginal contact, including sexual activities and vaginal health examinations.

They comprise varying substances with different benefits:

• Water based lubricants containing glycerin are popular. However, glycerin free options may be more suitable for people who get frequent yeast infections.
• Silicone based lubricants last longer than water based lubricants, making them a good option for people with severe vaginal dryness or a history of pain during sex. They are not safe to use with silicone sex toys, though, and they can be greasy.
• Oil based lubricants include many readily available products, such as kitchen oils. They are usually edible and are safe for the vagina, but they can be messy. Synthetic oil based lubricants, such as mineral oil and petroleum jelly, can work well but may also irritate the vulva.

Read more about using Vaseline or olive oil as a sexual lubricant.

Silicone and water based lubricants are safe to use with latex condoms. However, oil based lubricants may destroy latex condoms.

Some lubricants may affect sperm function, potentially decreasing the chances of a person getting pregnant, so those who are trying to conceive should choose a sperm friendly lubricant. People hoping to prevent pregnancy and use lubricants can consider using spermicides along with other contraceptives.

Vaginal moisturizers

Vaginal moisturizers are long acting lubricants that can help with chronic dryness. Their effects usually last for several days.

These products are a good option for people who experience intense vaginal dryness, even when they are not having sex. These moisturizers are safe to use alongside vaginal lubricants.

Some people use coconut oil for vaginal dryness. Studies suggest that coconut oil is an effective moisturizer for other body parts, but there is a lack of research on its benefits for the vagina. People should avoid using coconut oil with a latex condom, as it can break down the latex and make the condom ineffective.

Read about other home remedies for vaginal dryness.

Estrogen creams

Estrogen based creams can treat vaginal dryness that occurs due to low estrogen levels. These creams work by replacing lost estrogen, potentially reversing some of the effects of menopause and medical conditions that cause low estrogen.

Most of these creams require the user to decrease the dosage over time.

Estrogen creams can work well, but they are not safe for people who do not tolerate estrogen well. It is important to discuss with a doctor the risks and benefits of using estrogen cream.

How to use lubricant

When using over-the-counter lubricants and moisturizers, people should always follow the directions on the box.

It is best to start with a small amount of the product and then gradually increase the amount until the vagina feels comfortable. Some people find that reapplying the lubricant several times provides the best results.

A person may find it helpful to experiment with several different lubricants, paying attention to how their body responds to each one. If the vagina feels itchy or sore after using one of these products, this could indicate an allergy or sensitivity to an ingredient in the lubricant.

People should only try estrogen based creams after discussing their use with a healthcare professional. These creams often require a prescription. It is important to follow the directions for use and not exceed the dosage that a healthcare professional recommends.

Estrogen creams can take time to work, and it takes a few weeks for most people to see results.

Risks and side effects

                                           Staying hydrated may help prevent vaginal dryness.

Commercial lubricants are safe for most people.

However, as with any healthcare product, they present some risks, including:

• allergic reactions
• skin irritation
• yeast infections
• interfering with fertility
• drying up quickly, requiring frequent reapplication

When a person has clinical vaginal dryness, artificial lubricants do not treat the underlying problem. They will not increase estrogen or revive thinning vaginal tissue. People may, therefore, find that these products do not fully resolve the issue.

For those who do not get relief from vaginal dryness when they use commercial lubricants, estrogen creams may be a good option. Some other strategies that may help improve lubrication include:

• remaining hydrated
• having sex only when aroused
• spending more time on foreplay
• masturbating before sex
• increasing the frequency of masturbation or sex

                                                         SUMMARY

Vaginal lubrication can help people have better and more comfortable sexual experiences.

For people with vaginal dryness, the symptoms can be very uncomfortable or frustrating. A healthcare professional can help determine the cause of the dryness and then recommend a suitable solution.

Sex should not be painful, and the vagina should not be a source of discomfort. A person can see a doctor if vaginal dryness persists or does not get better with the use of a commercial lubricant.
