My fatherMy dad works for a computer gaming company called Code masters. He is a computer programmer that writes the instructions to make characters move around on the screen. He has been working in the industry for around 30 years but has been working for his current company for a year.
He has been educated as a doctor although he isn’t a doctor any more.How it worksMobile phones (also called a wireless phone or cellular phone) are used world wide by people of all ages to talk or text. Mobile phones are more expensive than most other types of communication. You can ether use pay as you go where you have to get top-ups or you can get it monthly where your texts and calls are free apart from one monthly charge. Mobile phones send and receive radio signals with any number of cell site base stations fitted with microwave antennas which are usually on the top of tall tower so the signal can reach the maximum amount of people in the area and so it can get to people who live in between mountains. It works by using satellites to connect to people all around the world originally invented as a way to speak to people anywhere.Model and featuresSamsung-E720It is a flip phone with a mega pixel camera with flash and video facilities. The main use of this phone is that you can call or text other people.
It also works as a music player and has email and internet browsing abilities. As well as this it has a calendar, notepad, calculator, games, voice recorder, currency converter and alarm clock.Uses of a mobile phone at workIf my dad is stuck in traffic he can use his mobile phone and phone home that he is going to be late or if he brakes down on the way to work and needs to phone to say he won’t be there on time.
He uses it to text, take pictures, play games and use a notepad or calendar on his phone. He could also send/receive emails when he is not near a computer to contact people rather than having to text.AdvantagesThe advantages to having a mobile phone are that you can communicate with suppliers, family or your colleges.
If you have not got use of a landline a mobile phone is a good alternative if you are stuck some where e.g. your car. Another advantage is that my dad can take interesting pictures or write work related information on his phone notepad to use at work. It is easy to carry around with him at work, you could not do this with a landline.
Texts are around 10p each and calls are around 15p per minute so it is very cheap to contact people.DisadvantagesA disadvantage to having a mobile phone at work is that the battery may run down and leave you with no form of contact. Another problem is that it could be stolen if you do not have a secure place to keep it. If you are in an important meeting your phone might start to ring and you would interrupt someone who is speaking. When my dad goes on holiday he has to take his mobile phone with him in case someone needs his help, this is bad because it interrupts the holiday.
Another disadvantage would be that with a landline you always get good signal but with a mobile phone you might have to go outside to get a decent signal.EvaluationThe mobile phone is very useful in the 21st century because a lot of people need to contact someone when they are on the move and landlines make this very hard so now almost everyone uses mobiles. This allows them to contact people on the other side of the world very cheaply and efficiently.Mobile phones can now be used to access the internet to find out information and to look at your email when you do not have a computer to use.My dad uses his phone mainly to phone home when he is going to be late from work or to phone work to say if he has broken down and will not be on time. He also uses it on holiday to use the internet and catch up on the news and his emails.
The mobile phone is not always useful because sometimes the battery runs down and you can be left with no form of contact. They also can ring unexpectedly and disrupt meetings, films and holidays. As well as this it will sometimes lose signal and you will have to go out side to phone someone clearly. Mobiles are getting smaller and smaller which makes them more portable so you can take them anywhere. This can also be a problem because they are easy to lose and are very easy to get stolen.
