NETWORK ARCHETECTURE

Network architecture is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats use. This concept was brought by Shreyas Dhakal In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.
The network architecture of the Internet is predominantly expressed by its use of the Internet Protocol Suite, rather than a specific model for interconnecting networks or nodes in the network, or the usage of specific types of hardware links.


1. PEER TO PEER

 Peer-to-peer architecture (P2P architecture) is a commonly used computer networking architecture in which each workstation, or node, has the same capabilities and responsibilities. It is often compared and contrasted to the classic client/server architecture, in which some computers are dedicated to serving others.

P2P may also be used to refer to a single software program designed so that each instance of the program may act as both client and server, with the same responsibilities and status.


2. CLIENT/SERVER

The client–server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients.^[1] Often clients and servers communicate over a computer network on separate hardware, but both client and server may reside in the same system. A server host runs one or more server programs which share their resources with clients. A client does not share any of its resources, but requests a server's content or service function. Clients therefore initiate communication sessions with servers which await incoming requests. Examples of computer applications that use the client–server model are Email, network printing, and the World Wide Web.

CHINESE NEW YEAR HOLIDAY TRIP

Assalamualaikum and hello everyone. 

For today's  post, i would like to share what i have been doing throughout my chinese new year and mid sem holidays. Besides spending my time being couch potato watching tons of movies, i made a short trip to kuala lumpur. But not to the tourists spot or fun place that i can enjoy myself . It's actually more to educational trip. The truth is, i followed my best friend who is a student of university malaya went back to her college. Well , speaking of university malaya, it is one of the top universities in the world. So , those intelligent people studied there.for me, to be offered to study in  university malaya was a blessed. . Lucky my friend and thanks to Allah for giving her the opportunity to be in such a wonderful and exciting ambience. Despite for her hardship in life back then , i'm happy she managed to come this far.instead, it was a blessing in disguise. 

So back to the objective of this post, my friend and i started the journey to kuala lumpur by bus on sunday morning. Everything seems to work out well. We thought it was going to be okay and we'll arrived there on evening as scheduled. But , luck was not on our side. The bus can't depart as there was some issues with the jabatan pengangkutan jalan (jpj). So we're busted and have nowhere to go. My friend became anxious. Well who's not? Tomorrow she got a class early in the morning. So we decided to take a bus from alor setar to ipoh, perak. If you are asking why we didn't took a bus to go to kl straight away, here is the answer---no bus. Of course ! There's no much choice i guess. So we took a bus to ipoh, perak on 1.00 p.m. then take ets train (literally we bought it online on the bus) from perak to kl sentral. As we depart, i can see she's began to calm down. Pheuuhh...

To add fuel to the fire, we missed the train to kl. Hahaha. It's because we're stuck in heavy jam along the highway plus road . We literally forgot the consequences for jam to happened as it is a chinese new year festive. Silly us.  So, our journey got delay several times on the road. We took 6 hours to arrive at perak. With dissapointment, we get off from the bus at amanjaya bus station with a new mission.to find a bus to kl. Luck was on our side, there's bus going there. Then, something funny and stupid had happened. As we approached to the bus, i remember that  i'd forgot to take my luggage in the bus. My adrenaline and  heart rate increases gradually . On that moment i feels so tired and just want this to be over. So i asked my friend to wait here while i went to dropped off place to get the bag which was on first floor.but, the bus was not there. I went downstairs and search in the bus section.  I'm so relieved. It was there. I thanked the uncle driver and i just felt like hugging him. Hahaha. Then, i went to my friend who was infront of the bus. 

I went panicked.there was no bus in lorong 6. "the bus had departed" i told myself. I looked at my friend with feeling blues. She hugged me and started to cry. I made this happened and i felt so wrong. I'm trembling apart. Then she said our bus was besides us while laughing and crying. The counter said the wrong lorong. Hahaaha.how could she be so dramatic. I thought we had lose the bus. Then, my friend went to the toilet.it took her soooo long as the bus already letting people came inside. Guess what, she bought breads at rotiboy. I was likee, laaaaaaaaaa. How could she...? Nevermind , we didnt ate since departed from alor setar.she knew that. So sweeeett.  Then,  we chill ourselves and depart on 8.00 p.m. on the bus, we have a long conversations as i had not seen her for long time. I told her im enjoying the journey today and it is very challenging.

Finally, we arrived at kuala lumpur on 2.00 p.m. we took uber to Universiti Malaya. In the room, we ate for late dinner which was prepared by her roomates. So kind of them. 

To make it short, here are some picture i took there. I walked alone in the evening for 6 km to make a survey. It's indeed beautiful place. And to add the moment i fell while climbing up stairs. So huimiliating. I also went to jalan masjid india alone as my friend got class. After 3 days stay, i went home to alor setar with ets train. 

So im concluding that no matter what happened, be strong and face it boldly.Thank you for reading...

GOOD PERSONAL HYGIENE (GIRLS)

Proper personal hygiene means taking care of every aspect of your body, from keeping it clean to looking your best. Basic hygiene should be taught to children at an early age to help establish good habits. Parents can reinforce good hygienic behavior by creating routines and being good role models. Personal hygiene practices include bathing, washing your hands, keeping your hair clean and brushing your teeth. Your personal, social and professional worlds are all affected by hygiene 

1. Shower

Shower or bathe every day. Bacteria feed on the sweat and skin cells that accumulate on your body throughout the day – that’s what causes body odor. Shower or bathe every day and use a mild soap to wash off the day’s dirt. Especially wash and carefully dry your feet, face, hands, armpits, and bottom.

2. Shampoo

Shampoo and condition your hair.Shampoo your hair 2-3 times a week. Washing your hair too often removes the natural oil and can make your hair dry.Choose shampoo and conditioner that’s right for you – whether your hair is dry, oily, frizzy, straight, or curly, there are many products that you can try.

Wet your hair with warm water. Pour a quarter-size amount of shampoo into your palm and massage it (not too hard) into your scalp and down to the tips of your hair. Wash the shampoo out then apply conditioner, using more for dry hair and less for oily hair. Let it sit in your hair for a few minutes while you clean your body, then rinse it out well.

If your hair gets oily near your scalp after a day or two, wash your hair daily or every other day using a mild shampoo. Use conditioner only on the tips of your hair, not on your scalp. Use “non-greasy” or “oil-free” styling products.

3. wash face

Use warm water and a gentle, non-abrasive cleanser to wash your face in the morning and before bed. Use just your fingertips to massage the cleanser onto your skin – using a washcloth or sponge can be irritating. Don’t scrub your skin hard. Rinse with warm water, and pat (don’t rub) your skin dry with a clean towel. 

Avoid products that exfoliate your skin or contain alcohol. Don’t use regular soap. These products are too harsh for your face.

If your skin is flaky, itchy, or dry, apply a dime-size amount of face moisturizer. If your skin feels irritated a lot or gets oily easily, use products for sensitive skin.

Also, wash your face after working out or sweating.

4. Wear clean clothes.

You don’t necessarily have to wash your clothes every time you wear them, but always wear clothes without stains, wrinkles, and smells on them. If you get your clothes dirty or sweat in them, wash them before wearing them again. Wear fresh underwear and a fresh bra every day.

Change your bed sheets every week, or more often if you sweat a lot during the night. Change your pillowcases weekly or every 2-3 days if you have oily skin.

6. Mini-hygiene kit

Carry small products around with you.Make a mini-hygiene kit to keep in your purse or backpack. Bring a packet of breath mints, gum, or a small bottle of mouthwash for after meals. Pack a small travel mirror, hand sanitizer, deodorant, a pack of Kleenex, and a small comb for everyday use.

7. good illness hygiene

Have good illness hygiene. If you’re sick, it’s important to practice good hygiene to protect others. Cover your mouth when you cough or sneeze. Wash your hands a lot, especially after coughing or sneezing. If you’re vomiting or have a fever, stay home and away from others.

Method Two of Four:
Practicing Good Grooming

8.  use deodorant

 It’s normal to have body odor, especially under your arms. Your armpits naturally sweat more once you go through puberty, and underarm hair can trap sweat and bacteria.Wear deodorant every day to feel and smell fresh. There are lots of different kinds of deodorant – roll-on, spray, stick, and those with or without antiperspirant (decreases sweating as well as covers odor). Some are perfumed and others are unscented. It’s up to you which kind to choose.

Different deodorants are marketed towards men and women, but really the only thing that’s different is how they smell.

9. Shave

Shave, if you want to. Whether or not you want to shave underarms, and private area is completely up to you. Long hair in your armpits and groin might trap moisture and odors, but showering regularly and keeping the area clean and dry should solve that. If you do shave, do it safely and hygienically:

Use clean, new, sharp razor blades and plenty of shaving cream or gel (not just regular soap). Never dry shave!

Take your time and go slowly. Ask your mom, aunt, or older sister for help or advice.

Do not shave your face. Pluck stray hairs or tweezers or try a bleach, cream, or wax that is formulated for facial hair. If you have lots of facial hair, see your doctor and ask about electrolysis or laser hair removal to get rid of it for good.

Use a non-greasy moisturizing lotion after you shave to keep your skin from drying out. Never use men’s aftershave – it stings!

Manage your pubic hair. Shaving your pubic hair might make the skin in that area itchy, irritated, or prone to ingrown hairs and folliculitis (infection of the hair follicle). Remember that it’s only up to you how you want to groom down there. You can shave your “bikini area” on your inner thighs and leave pubic hair natural, keep your pubic hair (carefully) trimmed with scissors, or stay completely natural. Just be sure to wash well in the shower. If you do decide to shave, follow these guidelines:

Use clean scissors to trim long hair first to make shaving easier (do this over the toilet so you don’t make a mess). Make sure no one else uses those scissors!

Soak in a hot bath or shower for a few minutes to soften the hair and skin.

Use a safety-razor (no straight blades or disposables), preferably with moisture strips.

Pull the skin tight and smooth, and shave in the direction of hair growth – be gentle, don’t apply much pressure.

Rinse off with warm water, pat the area dry, and use baby oil, aloe, or a non-perfumed moisturizer on your skin.

8. good dental hygiene.

 Brush your teeth, floss, and use mouthwash at least twice a day – after breakfast and before bed. This decreases tooth decay, gum disease, and bad breath. Try to use toothpaste or mouthwash with fluoride.If you have braces or aligners, you may want to brush after every meal.

Gently use your toothbrush to brush your tongue, too.

Get a new toothbrush every 3 months, or after you’re sick with something contagious like strep throat.

See your dentist about twice a year for checkups and cleanings.

9. keep contact lenses clean

 If you wear contact lenses, it’s important to keep them as clean as possible to prevent eye infections. Don’t just rinse them with tap water and reuse them, or reuse the same contact solution day after day – this is setting you up to put bacteria in your eye! Rinse your contacts well every time you take them out, clean your contact case thoroughly, and use fresh contact solution. Be sure to replace your contact case regularly, about every 3 months.

10. maintain a healthy feet

 It’s normal for your feet and shoes to start to smell, but you should try to keep this under control. Make sure your feet are dry before putting on socks and shoes. Alternate which shoes you wear, and let your shoes air out overnight somewhere ventilated (not the bottom of your closet). Wear socks with closed-toed shoes, and choose cotton socks instead of synthetic fibers.

If you have red, itchy, or scaly patches between your toes or on your feet, you might have Athlete’s foot. Avoid this by wearing flip-flops in school and locker room showers instead of going barefoot. If you need to, use an over-the-counter foot powder, or see your doctor for help.

11.Don’t overdo makeup.

 If you feel self-conscious about your skin you might be tempted to go heavy on your makeup. However, wearing too much makeup can make your skin dry or oily and cause breakouts. Only apply light layers of foundation and use makeup minimally for a natural, healthy look.

• There are techniques you can use to hide acne with makeup.

12. cut nails

Keep your finger and toenails trimmed and free of jagged edges. Clean underneath your nails when you wash your hands (and feet), and use an under nail scraper to get dirt out from under your nails if you need to.^[44] Use sharp clippers or small manicure scissors to cut straight across your nail, and round out the corners in a gentle curve with a nail file. Use hand lotion on your nails and cuticles.^[45]

• Don’t bite your nails or pull off hangnails. This can cause an infection and look messy. Use clean nail clippers, instead.^[46]
• Paint your nails if you want to! Or just apply a protective layer of nail hardener or top-coat for some shine.^[47] Only use acetone-free nail polish remover.^[48]

13.Wear some nice perfume, but not too much. 

If you want to wear perfume or body spray, go for it! Just avoid wearing too much. This can be overpowering and unpleasant to some people. Spray your perfume two to three times in front of you and then walk through it – this will give you a nice smell without being overpowering.

• Do not dunk your hairbrush in perfume or spray perfume directly onto your hair. This can dry your hair out.
• Remember, wearing perfume does not take the place of taking a bath or shower every day.
