    4. Securing the important and confidential data becomes easier and is safe for sure in 90% of the

    cases. The data stored on the server is safe and even if it gets deleted, there is a backup to restore it.

    Adding passwords or Secure Shell link access to the data helps it prevent from being exposed to

    hackers. In this way national database of different resources and criminal database, national security

    3/5

    Advantages and disadvantages of internet and mobile phones.

    What if the invention of mobile phones never happened?

    Well, we wouldn't be able to communicate the way we do now. Mobile phone history started

    in 1947 when Bell Labs engineers W. Rae Young and Douglas H. Ring realized that utilizing small

    hexagonal cells can increase the capacity of mobile phones for traffic at a substantial rate.However, at that time, the technology to do that was still nonexistent.

    Mobile Telephone system A (MTA) was the first mobile phone system that was fully automatic.

    This was created by Ericsson and was released commercially in Sweden during 1956. Mobile

    phones during this time weighed 40 kg. Thankfully, mobile phones have evolved into smaller

    versions since then. The Motorola DynaTAC 8000X was the first handheld mobile phone

    became available to the U.S. market in 1983. These mobile phones became increasingly popular

    during the 1980s because of the introduction of "cellular" phones which were based in cellular

    networks that had several base stations located close to each other. Analogue transmissions

    were being used by all mobile phone systems. It was Motorola that introduced the first truly

    portable handheld phone.The introduction of mobile phone systems such as IS-136, iDEN, IS-95, and GSM started during

    the 1990s. It was in the United States that the first digital cellular phone call was made. In 1991,

    Radiolinja, the first GSM network opened in Finland. Along with the introduction of 2G (2nd

    generation) systems were the tiny 100-200g handheld phones which instantly became the

    norm. This change was made possible by improvements in batteries and electronics. The 2G

    phone systems were characterized by the introduction of fast and advanced phone to network

    signaling as well as digital circuit switched transmission.

    Roughly ten years later, 3G (3rd generation) was launched by NTT DoCoMo in Japan. These

    mobiles already offer TV and video services, which has made these gadgets even more popular.

    Quite a number of these phones can also connect to the Internet, which makes themmultimedia computers already. It is said that in the future, 4G (4th generation) system will also

    be introduced. This will pave the way for low cost, high speed data transmission. This will also

    offer users with a high degree of synchronization and personalization between a wide array of

    user applications.

    Advantages:

    1. The more you talk, the more you know how to talk and the better your communication skillsbecome. This is applicable if youre a sensible person and keep note of your interacting habits

    over the phone. It can be a communication tutorial!

    2. Nothing more than a cell phone comes to great help in emergency. You are driving by thefreeway and the vehicle jams and cell phone comes to your rescue. You are stuck in a lone

    place, again call somebody and ask for directions.

    3. Parents can be a little less worried about their kids by being in constant touch with them.4. If youre a net-savvy, you can have Internet handy all the time and anywhere the signal of your

    cell phone provider can reach.

    5. Trendy and stylish cell phones can be used as a bait to receive attention. It can be part offashion and styling.

    6. From the industry and economy point of view, cell phone companies (communication industry)are flourishing with market capital in billions. This is a good thing for the economy to be

    smooth and healthy.

    7. Companies find it yet another medium to advertise their products; so another medium toreach the consumers.

    8. Nowadays, cell phones are not just phone calls; theyre about messaging, vidoe, songs, games,alarm clock, notes, calendar, reminder, etc. So one equipment, lots of uses!

    9. Although cell phone use can be dangerous while driving but sometimes it can be a time-saver -you are driving and simultaneously discussing some urgent matter as well. A sensible and only

    urgent usage during driving can be a great help at times.

    DISADVANTAGES OF MOBILE

    Mobile phones transmit and receive Radio Frequency (RF) signals in order to communicate. TheRF signals from mobile phones fall within the microwave part of the electromagnetic spectrum.

    This radiation is also referred to as microwave radiation or electromagnetic radiation. In short:

    Mobile phones use microwave radiation to communicate and these are harmful for human

    being.

    Conversation on cell phones, both hand-held and hands free was found to influence driving

    performance. Epidemiological findings consistently showed an increase in crashes associated

    with use of cell phones.

    More use of mobiles by young children made following problems in their health:

    Depression increased by up to 64-fold. Fatigue increased by up to 37-fold. Appetite Loss increased by up to 25-fold.

    The popular belief that adverse health effects can be induced only by the heating effect of [cell

    phone] radiation is a fallacy

    Advantages and disadvantages of internet and mobile phones.

    Students in schools and colleges use features such as games, internet facilities during the

    for this new technology. Just like computer viruses, these viruses will affect the normal usage

    on mobile phones making them to malfunction and causing destructions.
