Pros and Cons of using a Mobile Phone in public

Pros

Safety – In planes and hospitals, phones can interfere with equipment. A 1997 ‘New England Journal of Medicine’ study found that talking on a phone while driving increased the risk of an accident by 4. This is almost equal to the danger from driving drunk.

Peace and quiet – Many people go to places such as libraries to focus and do work. People talking on the phone in places like this are distracting. Even when people go out to a restaurant, they feel entitled to a relaxed atmosphere, as some mobile phone users use language inappropriate for anyone to hear, especially young children.

Inconveniencing others – Mobile phone users will usually multitask, trying to carry on a conversation while using an ATM, driving or buying something from a shop. Their divided attention becomes an obstruction to the cashier and an inconvenience to those behind them who have to wait longer.

Cons

Safety – Some argue that having 999 at the touch of a button is critical to maintain personal security. Mobile phone bans impede drivers’ ability to report an accident, road rage incident, medical emergency or crime. Drivers assert the importance of calling for directions if lost or receive help if their car breaks down.

Emergencies – As genuine emergencies do occur, some calls can’t wait. People who have sick or elderly family members, parents expecting an important call from their child and those in the middle of a crisis believe it’s acceptable to leave their phones on in public.

Personal freedom – Cell phone bans may intrude on their personal freedom. As they pay high monthly price for this communication option, they believe they can use the devices wherever and whenever they choose.

Online Marketing

Online Marketing

Methods of shopping are switching to online methods department stores, mail order, telephone order are all doing this as most people start looking online before going anywhere else. We hardly see catalogues anymore, it costs way too much and is unnecessary as people didn’t seem to want catalogues anymore as there are easier and better methods. An online store is pretty much a catalogue as it has all of the products in one place and has more information than just the price, a picture and a small description. Online you get customer reviews, ratings, delivery; special offers may also become available through online purchase. An online is also more eco-friendly as it saves the overuse of paper.

Argos is one of the few companies that have scrapped using a catalogue. Companies such as Littlewoods, Ikea and Wickes still use catalogues.

IMAP4 vs POP3

Internet message access protocol is one of the two most prevalent Internet standard protocols for getting e-mails, the other protocol is Post office protocol. Virtually all modern email clients and mail servers support both protocols as a means of transferring email messages from a server.

POP3	IMAP
Since email needs to be downloaded into desktop PC before being displayed, you may have the following problems for POP3 access: You need to download all email again when using another desktop PC to check your email. May get confused if you need to check email both in the office and at home. The downloaded email may be deleted from the server depending on the setting of your email client.	Since email is kept on server, it would gain the following benefits for IMAP access: No need to download all email when using other desktop PC to check your email. Easier to identify the unread email.
All messages as well as their attachments will be downloaded into desktop PC during the 'check new email' process.	A whole message will be downloaded only when it is opened for display from its content.
Mailboxes can only be created on desktop PC. There is only one mailbox (INBOX) exists on the server.	Multiple mailboxes can be created on the desktop PC as well as on the server.
Filters can transfer incoming/outgoing messages only to local mailboxes.	Filters can transfer incoming/outgoing messages to other mailboxes no matter where the mailboxes locate (on the server or the PC).
Outgoing email is stored only locally on the desktop PC.	Outgoing email can be filtered to a mailbox on server for accessibility from other machine.
Messages are deleted on the desktop PC. Comparatively, it is inconvenient to clean up your mailbox on the server.	Messages can be deleted directly on the server to make it more convenient to clean up your mailbox on the server.
Messages may be reloaded onto desktop PC several times due to the corruption of system files.	The occurrence of reloading messages from the server to PC is much less when compared to POP3.

POP3 maintains a collection of text files - one for each e-mail account. When a message arrives, the POP3 server simply appends it to the bottom of the recipient's file.

Using IMAP an email client program can not only retrieve email but can also manipulate message stored on the server, without having to actually retrieve the messages. So messages can be deleted, have their status changed, multiple mail boxes can be managed, etc.
