musta people..?did you enjoy your day?

kinds of computers

Yesterday's Computers

Charles Babbage produced a design for a mechanical computation engine back in the nineteenth century.  The precision he demanded of the engineering was not possible at the time so it was not completed.  Modern computing involves electronic circuits of one kind or another.  Blaise Pascal, a French Mathematician, produced an idea for a digital computer at about the same time.

An electromechanical machine called Collossus was used in the Second World War to crack the Enigma encryption codes used by the German Army.  It was so good that it could crack Enigma codes faster than a modern PC with a Pentium processor

 

The earliest  fully electronic computer was built by the US Navy during the Second World War under the supervision of Grace Hopper.   It was she who coined the phrase “bug” for a program error, when a moth shorted out a couple of wires.  It was she who invented the first computing language, ATP, and she verified the language COBOL which was widely used in industry.  She was at the forefront of computer development.  As an officer of the Naval Reserve, she achieved the rank of Admiral.

All these early machines were huge, needed large amounts of electricity to keep them going, and specialised people to run them, and interpret the output.  Programming them was difficult as they needed to use machine code, the series of 1’s and 0’s that the computer uses.  Finding errors was time consuming and difficult.

An American company, International Business Machines, was one of the first to go into commercial production of computers.  Its Chairman was famously quoted that he reckoned that there was a market for four or five of these machines worldwide.  The main problem was that these machines used thermionic valves (“toobs”) in their electronics.  They used a vast amount of electricity and were none too reliable.

Question 13  Explain why computers were not widespread in the nineteen-fifties. ANSWER

When the transistor was invented and perfected in the mid nineteen-fifties, the complex circuitry within a computer could be made into a manageable size.  Contrary to expectations, the computer rapidly became a “must have” for large corporations.  These were vast machines called mainframes which needed large buildings and a good number of specialised staff to operate them.  COBOL (Common Business Oriented Language) was a common language used by these machines, along with the EBCDIC character codes. The picture shows a mainframe:

Mainframes are still in use in some corporations because of the huge sums of money invested.  However many mainframes have less computing power than PCs and only survive due to the economics.

Mini-computers are smaller versions of mainframes.  Some of these were based on the analogue concept, in which the operational amplifier was at the heart.  Analogue computing is almost completely unknown nowadays.

The microcomputer is the generic name for a number of different kinds of small computer, of which the most common is now the PC.  When microcomputers came in, in the late seventies, they had taken advantage of the rapidly falling price of integrated circuit chips.  Some of these were designed at the home market.  Examples include the Sinclair Spectrum, and the Amiga.

The British Broadcasting Corporation sponsored the design of a microcomputer which became very common in schools.  The picture below shows a BBC microcomputer.

These machines had a very simple operating system, and were easy to run.  Many people used them to write their own software; there was little commercially available software.  A number of teenagers made a lot of money by producing software in their bedrooms.

The graphics were crude, and there was little memory.  Auxiliary storage was on 5 inch floppy disks that were even cruder than present floppy disk.  Some programs were even recoded on audio cassette.  Sometimes the programs were broadcast on the radio.  The transmission sounded like a nest of angry bees.   Some software was available on pre-programmed chip.  Access to these was remarkably easy.  For Interword, a word processor, you typed “*IW.”.  The BBC was very good at:

• Data-logging
• Word-processing
• Spreadsheets

The old BBCs were very reliable.  If the programs did go wrong, the computer could be restored by pressing the BREAK key, and the program could be reloaded by pressing SHIFT + BREAK.  BBC computers still are in use in some schools.  The BBC was overtaken by  the Archimedes which, in its later versions could be configured to run like a PC.

history of computers

A computer is a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations. The particular sequence of operations can be changed readily, allowing the computer to solve more than one kind of problem.
Conventionally a computer consists of some form of memory for data storage, at least one element that carries out arithmetic and logic operations, and a sequencing and control element that can change the order of operations based on the information that is stored. Peripheral devices allow information to be entered from an external source, and allow the results of operations to be sent out.
A computer's processing unit executes series of instructions that make it read, manipulate and then store data. Conditional instructions change the sequence of instructions as a function of the current state of the machine or its environment.
The first electronic computers were developed in the mid-20th century (1940–1945). Originally, they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).^[1]
Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.^[2] Simple computers are small enough to fit into mobile devices, and mobile computers can be powered by small batteries. Personal computers in their various forms are icons of the Information Age and are what most people think of as "computers". However, the embedded computers found in many devices from mp3 players to fighter aircraft and from toys to industrial robots are the most numerous

can you prove this?page 34

 a classmate of yours says that a good product or service will always have a market ,but another one argues that no matter how attractive a product or service is, it will not succeed in the market if there isn't a demand for it.
 1. can your first classmate be correct? can people really be willing to buy a product or avail of a service even when they dont need it? no, because you will just spend money for a thing you dont need.
 2.is it posible to create a demand for a product or service where there was none before?explain your answer.
  yes to encourage your creativity and imagination..

do you understand page 34

1.aside from food, what are the others basic needs of people that an entreprenuer can supply?
shelter,clothing, and money

2. why is earning a profit while answering the needs of people an important part of entrepreneurship?
 so when calamity comes you have money to spend fr the things you need.

        Ana's brother has a successful internet cafe located on a busy street near two colleges. she was inspired by his brothers sucecess and put up the sama business starting witn 6 computer  units with internet access.but ana had no choice but to set her business up in front of public elementary school. in six months, she had to close down her internet cafe because of lack of costumers.

       Based on your learning on environmental scanning, why do you think ana's business fail?what could have been a better bussines to set up in the area?

answer:the students goes thre during class hours.on some home village she can also build her intenet cafe.

This allows the firm to act quickly, take advantage of opportunities before ... and respond to environmental threats before significant damage is done” (2). ... Environmental scanning includes both looking at information (viewing)

Environmental scanning is one component of the global environmental analysis. Environmental monitoring, environmental forecasting and environmental assessment complete the global environmental analysis. Environmental scanning refers to the macro environment.The global environment refers to the macro environment which comprises industries, markets, companies, clients and competitors. Consequently, there exist corresponding analyses on the micro-level. Suppliers, customers and competitors representing the micro environment of a company are analyzed within the industry analysis.^[1]
