Discussion
I have seen all these marketing methods in operation. The most effective method for selling a car would be: Advertising on the TV, newspapers and Exhibiting at Trade fairs. The most effecting advertising method for a new vacuum would be: handing out flyers, Advertising on TV and advertising in magazines.
Advertising
Advertisements for magazines and newspapers are commonly produced by using desktop publishing software. Posters and flyers will be produced in a similar way. Pictures may be created in a graphic package, and photos may be scanned and imported.
Creating a Website
Having a company is an excellent way of marketing a product or service. An online catalogue has several advantages over a paper one: it costs less to produce; it does not have to be mailed out and it can be kept right up to date.
Direct Mail
Sending letters, catalogues and free samples to carefully selected people can be a very effective way of marketing new products. A database of names and addresses is combined with a word-processed document in a mail merge operation. This creates, for example, personalised letters to each recipient.
Some companies specialise in direct mail. They keep up-to-date lists of organisations that might be interested in particular products or services. For example, a drugs company might want a list of all doctors’ surgeries in a particular area.
System maintenance
Keeping data safe and computers running smoothly is crucial for organisations of keeping data safe. Many small companies install expensive IT systems but do not have any kind of technical support. The cost of having no proper backup can be devastating. A recent survey concluded that a company unable to get at its data for 10 day will never fully recover and 43% of them will go under.
Backups
Backing up data on a regular basis, usually every day is vital if data is not to be lost when disaster strikes. Backup copies must be kept in case of fire or theft.
THE CPU
The Components of a Computer
All computers, whatever their size or function, have certain components. They have input devices for reading data into main memory, a central processing unit for processing data, output devices and printing, displaying or outputting information, and storage devices for permanent storage of program and data.
The CPU
The CPU is the brains of the computer. This is where all the processing and calculations take place it consists of 2 different parts:
The Processor
The processor contains the control unit and the arithmetic/logic unit (ALU).
The control unit coordinates and controls all the operations carried out by the computer. It repeats by repeating 3 operations:
- Fetch – cause the next instruction to be fetched from the main memory;
- Decode – translate the program instruction into commands that the computer can process;
- Execute – cause the instruction to be executed.
The ALU can perform 2 sorts of operations on data. Arithmetic operations include addition, subtraction, multiplication and division. Logical operations consist of comparing one data item with another to determine whether the first data item is smaller than, equal to or greater than the second data item.
Memory
There are basically 2 kinds of memory: Random Access memory (RAM) and Read-only Memory (ROM).
RAM is divided into millions of addressable storage units called bytes. One byte can hold 1 character, or it can be used to hold a code representing, for example, a tiny part of a picture or part of a computer program instruction.
In contrast ROM is not even mentioned. A PC will only have a small amount of ROM, and you wont get a chance to use it because all the instructions held in ROM have to be burned into the memory chip before it leaves the factory.
Processor Speed.
The speed of the processor is one of the main factors that determines how fast the computer processes the instructions.
The other factor is to determine the performance of a computer is the amount of memory it has. Modern software takes up a huge amount of software. Increasing a computers memory will help to alleviate this problem.
You can find out how much memory your computer has by clicking start, Programs, Accessories, System tools, System information.
Exercises
The physical memory of the computer being used is 261,618Kb. This is 2.6Mb.
The total physical memory of my computer is 256.00MB and the total available memory is 39.40MB. When I closed almost all the application except for Microsoft word the available memory went up to 54.98MB.
