Electronic Mail has good and bad features. If we compare E-Mail with the telephone and postal mail, we will find similarities.
Advantages
- E-mail is relatively fast. With electronic mail, the delivery of a message can take a few seconds to a day or so depending on the network transmission and the delay in the recipient's reading.
- E-mail is asynchronous communication, which means communication that does not occur at the same time. In e-mail, the sender sends a message and the recipient reads it at his/her own convenience. This is very useful for communicating between long distances and different world time zones.
- E-mail is not formal but some "Netiquette/Intern etiquette" rules apply. On the phone or in a letter, the formality you use depends on your correspondent. Be careful when you send message to people you do not know! They will know you only by what you send them. Be sure that what you send is correct and readable.
- E-mail is inexpensive. E-mail allows you to have a large number of correspondents, over a wide geographical area with the cost of a single local call. E-mail at Vanderbilt is 'free' for you. Other On-Line services charge a relatively small amount.
Disadvantages
- Security and privacy are quite low with e-mail. The majority of the e-mails are delivered to the correct addressee without intervention. Sometimes, however, individuals other than the sender or recipient may intercept messages. This could occur because of an incorrect address, system administrator intervention, or transmission error.
Advantages and Disadvantages of Laptops and Desktops
Prospects & Potential Uses
Portable printers are a boon for busy executives and those in sales professions. Presentations, contracts, newsletters, and anything else you need away from the office – all can be printed from anywhere.
Drawbacks
One drawback to portable printing is replacement ink cartridges. Because the cartridges are smaller, they will need to be replaced often and that can be expensive. Another drawback is compatibility issues. Make sure that the portable printer you purchase is compatible with the operating system of your laptop or PC. Also, keep in mind that with some models, a USB cable is not included with the printer and must be purchased separately.
The advertised weight of the printer usually doesn't include the power adapter, batteries, cables or paper that you'll have to lug around with the printer.
Costs
Portable printers and their accessories can be pricey, ranging from a low of £175 for non-colour thermal transfer printers to a high of £280 for a colour ink-jet model.
Since portable printers tend to use very small cartridges or ribbons, they ultimately cost more per page to print. Expect to pay more per page for thermal transfer printers and as much more per page for some ink-jet printers. Colour printer costs are even higher.
TASK 3:
J.I.T. (Just In Time).
Just-in-Time (JIT) manufacturing
- High level of information flow and real-time control needed
- Reduce inventory levels
Just-in-time manufacturing is a major innovation created and cited by the automotive industry for its ability to cut warehousing costs at the same time it improves quality.
Manufacturers have found it isn't necessary to maintain warehouses full of parts or even keep many parts bins on the factory floor. Instead, a stream of suppliers' trucks drive up to the auto makers' loading docks, delivering everything necessary to manufacture vehicles on the line that day. In many cases, the auto factory ordered the parts in specific colours and sizes or with special options less than three hours before delivery.
Such precision can happen - and is expected - when the supplier factory is located right next door to the automotive manufacturer.
The just-in-time (JIT) delivery that auto manufacturers require is one reason many suppliers are adopting right-next-door, right-up-the-road, or just-a-few-hours-away strategies when deciding where to locate their own new manufacturing plants. And, conversely, when automotive manufacturers start poring over maps to figure out where to site their own new factories, they usually pushpin the locations of their existing suppliers as a factor in their own decision-making process.
Certainly, the supplier strategy of building factories and distribution centres near primary customers is not new. It is the reason the domestic auto supply industry grew strongest in Michigan. That was where the entrepreneurs who first developed Ford, Chrysler and General Motors lived, where they built their companies, and why "Detroit" became a synonym for the Big Three.
These site selection rules, developed more than a hundred years ago, still seem to apply today. Be close to the primary customer so deliveries can be made on time. Be on a major road network so customer shipments can leave regularly. Find a trainable work force with both a strong work ethic and a sense of manufacturing, though not necessarily any knowledge or background in automotive products. Today, most automotive manufacturers add another factor: Locate where a national distribution system can deliver the vehicles to every car lot in the country.
A.G.V. (Automated Guided Vehicles).
Reasons for Automating
- Increase production rate
eliminate portions of process that directly increase production time:
machine processing time, handling time, setup times (SMED)
- Remove humans from hazardous environments
exposure to chemicals, fumes, temperature or radiation
robotic applications: L/UL furnaces, spray painting, welding
- Remove humans from processes that require extremely clean environments
semiconductors, drugs
reduce number of defective products
- Reduce direct labour
one worker monitors a larger number of machines
- Reduce work-in-process
parts being processed, part waiting to be processed
large WIP: longer time to fill orders, more storage space, value of unfinished goods that could be invested elsewhere
reduced WIP: better control and scheduling, minimize batch size
- Reduce manufacturing lead time
processing time, setup time, waiting time
setup time: flexible automation, common fixtures and tooling
processing time: combining or eliminating operations, increase speed (work measurement principles)
- Increase quality
repeatable operations through every cycle - tighter control limits, easier detection when process is out of control
status of manufacturing operations
- Increase productivity
not the primary reason for automation
Types of Automation
Fixed automation
- Hard automation, automation for mass production
- Produces large numbers of nearly identical parts
- Cost is greater than programmable or flexible - high production volumes
- Product design be stable over its life
- Advantages: equipment fine tuned to application - decreased cycle time, infrequent setups, automated material handling - fast and efficient movement of parts, very little WIP
Programmable automation
- Smaller volumes of many different parts
- More flexible than hard automation
- Major disadvantage: setup prior to each new part
- Large batch size (due to setups)
- Speed sacrificed for flexibility
Flexible automation
- Compromise between fixed and programmable automation in speed and flexibility
- Advantage: programming and setup performed off-line
- More expensive - size and tool change capabilities
- Small batch sizes are justified - reduced WIP and lead time
- High volume to justify
- Typical parts are expensive, large and require some complex machining
- Production costs lower than fixed or programmable automation for some parts
TASK 4:
The Pros and Cons of Smart Cards
Smart cards, which contain a microprocessor rather than a magnetic strip, are both a good and bad. They can make your life easier, and possibly safer, by putting an incredible amount of important information at your fingertips. At the same time, however, the compromise of that information can be devastating to you. So, are they worth the risk?
Let's take a look at the paranoia that's going around. In the first place, you might fear that someone can use these cards to track you. You may also worry that unscrupulous merchants can see a record of everything you've purchased, and then sell the information to someone else. The truth is, while it's possible that these fears will come true, they probably won't in the near term.
Regardless of whether you use a credit card or a smart card, somebody knows where you've been
one reason for this is that smart cards, as "money cards," are only slightly more advanced than credit cards. A smart card may temporarily store your transaction record, possibly making it available to other merchants. So, regardless of whether you use a credit card or a smart card, somebody knows where you've been. On the plus side, merchants are probably going to get their smart-card readers from banks, and it's unlikely that banks will provide merchants with the capability of reading the details of previous transactions off the cards.
Information Theft
However, it's possible that a merchant could acquire a box that enables him to steal the information. So, you have to ask yourself, "Is the risk of that action worth the benefit?" The reality of the situation is that even if financial information is compromised-- more than it currently can be with credit cards-- how does that really affect you? In most cases, the benefits seriously outweigh the potential negative effects.
In most cases, the benefits seriously outweigh the potential negative effects, if you have a smart card that contains medical information, you should protect it with your life. I would hope that if smart cards contain medical information, they're used only for transactions related to medicine. Giving people a single, all-inclusive card would be very stupid. I would also hope that people are smart enough not to give out their cards freely. They should use common sense, which all too many people seem to lack.
Whether the smart card is for monetary or medical purposes, the biggest risk that people face from the card arises from loss or theft. No matter what sort of protections are built into the system, if you don't physically protect your card, laws and security measures aren't going to do you any good.
TASK 5:
Seating - Chairs with adjustable height and backrest are recommended. When seated correctly, the lower arms and thighs should be in a roughly horizontal position while working at the keyboard.
Worktops - A fixed height between 660-730mm is required (720mm is recommended). A worktop depth of 760-840 mm is required to give the user sufficient distance from the screen while working. Matt worktops in a cream or beige colour are recommended in order to reduce glare.
Lighting - Windows should be fitted with non-reflective blinds, preferably beige in colour. Consideration should be given to positioning of the screen away from light reflection and glare. The optimum position is at right angles to the source of natural light.
Screens - All new screens must be fitted with tilt and swivel stands. Sufficient room is needed for the screen to be moved back and forward. Ideally, the top of the screen should be at eye level.
Power supply - Leads should preferably be in trucking above the height of the worktops or be safely tied. An adequate number of supply sockets should be provided to eliminate the need for trailing wires. It is safer to switch the equipment off at the wall socket or room master switch rather than 'find' the switches at the rear of the machines. Mains plugs and leads must be checked for safety once a year.
Fire precautions - A fire extinguisher suitable for electrical fires (such as carbon dioxide) must be provided in all computer rooms. The location of the nearest fire exit must be notified near the door in each room.
Repetitive Strain Injury - repetitive finger movements over very long periods of time may cause this. It can become quite serious for people employed solely as keyboard operators. In order to reduce muscle .fatigue and strain, users should be encouraged to get up and move around at reasonably frequent intervals, for example to collect equipment, and to do other forms of work.
Eye Strain - In order to reduce eyestrain, users should be encouraged to look away from the screen and focus on a distant object from time to time - this will relax their eye muscles. The wearing of spectacles also helps prevent possible soreness caused by the bombardment of ionised dust particles from the screen.
TASK 6:
- Copyright, Designs and Patients Act.
Copyright, Designs and Patent Act 1988
Duration of copyright
The computer programs regulations in 1992 extended the rules covering literary works to include computer programs.
Types of work covered
Rights do not subsist in any part of a work which is a copy taken from a previous work.
Betty and Daniel should find out if the images they are using are copyrighted and if they are they should ask if they are allowed to use it on their products. If the image is a copy of a copied image then there if no copyright protecting it.
- 'A Paperless Office' - fact or fiction.
Many businesses feel that they are drowning in a sea of paper. Studies show that offices increase their paper demands by 25 per cent per year; retention periods are becoming longer and access to the documents is becoming greater. The answer lies in Electronic Document Management (EMD) systems, writes.
Document management systems have been around since the time of stone tablets.
The use of filing cabinets, file folders, and index cards comprise some of the components of a document management system. The ability to efficiently store documents and easily search and retrieve their contents has been a constant struggle for records managers.
While microfilm is a good solution for permanent storage, its search and retrieval mechanisms are cumbersome. Enter the use of computers to manage document storage and increase search and retrieval capabilities. EDM systems offer secure archive capabilities, elimination of lost or decaying documents, and instantaneous access to all of the documents in the repository.
Today, a document can be scanned into a computer and the user can search a template profile or search the entire text of the document.
CD ROM’s had over a 30-year shelf life and can store over 20,000 documents. A document that is stored on a computer can be easily located, and once it is found it can be printed, faxed or e-mailed. Another advantage of an EDM system is its archival abilities.
Imagine storing 10 file cabinets worth of paper documents in your desk drawer, and being able to retrieve any document within 30 seconds! What is the cost to all of this paper? Consider that an average company spends £25,000 to fill one file cabinet and £2,100 a year to maintain the cabinet.
While vast improvements have been made over the past few years, an EDM system may not completely abolish a company’s paper requirements, but it will exponentially allow for better management of those documents. An EDM system may be the solution your company is seeking, so that you can concentrate on managing your business, not on managing your paper.
TASK 7:
E-Booking.
The facilities offered for e-booking on the internet are very vast; there are many companies that offer online booking. By going to any major search engine such as ‘Google’, you will find many companies offering there service for online booking of flights, such as airline companies them selves and online travel agents
As you can see there are many options for online booking on the internet.
Sixth Form Colleges.
The facilities offered for researching Sixth Form Colleges on the internet depend on whether or not the college has a website there are many companies that offer online booking. By going to any major search engine such as ‘Yahoo’, you will find some Colleges offering an online guild to the Sixth Form College.
As you can see there are many options for finding a college on the internet.
Advantages And Disadvantages Of Using The Internet For The Family And Environment.
Compare Booking A Flight Online Or Through A Travel Agent.
- Easier to do online, you don’t have to leave your home.
- Might be able to get better offers online.
- When you go to a travel agent, it is easier to find exactly what you want because you are talking to a human and not a computer.
- The internet site might not be secure and someone may get your details.
Compare Researching Sixth Form Colleges Online Or Manually.
- Manually is better because you can see the college you want to go to and you can talk to people at the college.
- The internet is good to find out statistics about a college.
- When searching for a college on the internet you can end up with some which are nowhere near you and are irrelevant.
Employment Due To Internet Growth.
There has been a growth in employment due to the internet as staff are needed to maintain the site, work in warehouse and deliver goods. This has also created new jobs such as website designers and internet technician.
