Introduction Computer systems can be found in varying environments, these are; at home, in businesses, computer gaming, networking and real-time situations. Computers systems can be classified into the following categories; microcomputers, minicomputers, mainframes and super computers. Different environments will have certain computer systems which are appropriate for that setting. Microcomputers can be categorised as personal computers (PC’s) and mobile computers. Mobile computers can be devices such as laptops, PDA’s, smart phones and tablets. Microcomputers are the most used type of computer system in existence today, the reason for this is they are the cheapest and smallest of all. Most microcomputers have a single-chip processor, memory …show more content…
Workstations can be interpreted as two ways. Traditionally a workstation was known as a computer connected to a network such as the internet, but now it’s also common to refer to workstations as computers that are slightly more powerful than a personal computer. The definition of a workstation in the oxford online dictionary is “a desktop computer terminal, typically networked and more powerful than a personal computer”(http://www.oxforddictionaries.com/). Furthermore, minicomputers are not designed for single use. Minicomputers have had the following effects on environment: Home – Minicomputers aren’t usually found in the home environment. A user could work from the home but then that environment would become a business environment. Business – The business environment is where the minicomputers can be found the most. Small business and firms use minicomputers. A firm would use minicomputers at departmental level. One department may for example use a workstation to monitor production processes. Architects and engineers also use workstations. An engineering firm may find that a microcomputer doesn’t have the processing power to complete engineering tasks and a workstation is …show more content…
Thanks to mainframes users can do online banking or withdraw money from an ATM. Although a microcomputer will needed to access the customer’s account, a mainframe handles the process of transferring money. Airline companies such as British Airways use mainframes to allow users to book seats online. When a seat is booked the mainframe operates quickly so that taken seat isn’t booked by another user. Hotels likewise use mainframes to allow users to make online bookings. Supercomputers are high performance systems used for multiprocessing. They are the most expensive and largest of all computer system types. They are also the least common. They are usually found a large ventilated rooms sometimes the size of a building. Supercomputers like mainframes can be found in business and real-time. Business - Companies and governments use supercomputers for research and exploration. NASA uses supercomputers for space shuttle launches, control and space exploration. No other type of computer system will be able to do this. Governments and companies also sue supercomputers for weather forecasting Supercomputers handle large amount of data from different locations to predict the
decision that is very important if you decide to buy a computer for work or home
1. A device is a computer if it has an input device, central processing unit (CPU), internal memory, storage, and an output device.
The invention of computers has made a huge change in human civilization and society, by changing the way people think. Computers replaced jobs and tedious repetitive thoughts that were done by human originally. People became more and more reliant on computers, and thus, computers became essential to our lives. Computers can manufacture products quickly, and eliminate possible human errors. As technology progresses, new ideas have been brought into computer to make them perform more efficiently. Also, scientists and engineers tend to make things “smaller”, so we can enjoy the benefits from electronic devices anywhere and anytime. Therefore, size and efficiency are two main points for consumers. Desktop computer and laptop computer are representatives for each of these concepts. Although desktops and laptops come from the same origin, they are different in many ways.
While we still wish to remain in the production of personal computers, we have determined that we would need to dedicate 25% of our current production efforts to the marketing and manufacturing of our new line of business computers. Since these new computers have similar parts as our current line of personal computers, it will be easier on our production line workers who are already familiar with our existing hardware. In regards to this, we have decided to not enter the field of tablet computers as we are uncertain of their long-term success and would require additional factory worker assembly training. The launch of our new Dynacorp business computers will roughly take about a year to fully complete as we plan on spending 3-4 months each in the areas of conducting market research, product design, manufacturing and product evaluation. We also plan on marketing this product towards our current personal computer user base by offering them a loyalty discount for our new line of computers, as well as towards smaller businesses who may lack the funds to purchase top-line models. We also plan to use this initial launch as a prototype for future models depending on any changes in market demand or responses from our
Using the specification given on the task sheet I will recommend hardware, software and peripherals Paul can use in order to achieve the work-style given (Home-based office). I will take into consideration the constraints; such as lack of space in his ‘small box room’. As a postage destination is not included, I will only include the retail price of the product without p&p.
-use of microprocessors have led to appliances such as phones, computers ,TV, washing machines and other home appliances which has improved communication, lifestyle conveniences and provides society with entertainment.
"Technology is like fish. The longer it stays on the shelf, the less desirable it becomes." (1) Since the dawn of computers, there has always been a want for a faster, better technology. These needs can be provided for quickly, but become obsolete even quicker. In 1981, the first "true portable computer", the Osborne 1 was introduced by the Osborne Computer Corporation. (2) This computer revolutionized the way that computers were used and introduced a brand new working opportunity.
Computers are one of the most popular kinds of electronic devices in the world today. Whether kid or adult, male or female, everyone wants to learn how to operate the computer. People use computers for different purposes such as typing papers, creating websites, making presentations, browsing on the internet, playing games, etc. In fact, many people are still confused about choosing what kind of computer they want to buy. In the world today, there are two types of computers: notebook/laptop and desktop. They both are actually very different in several ways. In this paper, I will compare the size, connectivity, power, and price of notebook and desktop computers. I can make these comparisons because I have both a notebook and a desktop computer in my apartment.
System units are commonly mistaken as the Central Processing unit (CPU). System units sometimes called “computer chassis”, “base units” or “Tower cases” however are simply the housing for the integral parts of a computer. System units usual house all components of a computer excluding the monitor, Keyboard and mouse. System Units are a very simple component of the computer because they do none of the actual computing. They are usually just a square or rectangular prism made of some type of plastic or metal that hold all of the vital parts of a computer in a secure manner. Other than that there is not much to be said about the system unit.
We have the microprocessor to thank for all of our consumer electronic devices, because without them, our devices would be much larger. Microprocessors are the feat of generations of research and development. Microprocessors were invented in 1972 by Intel Corporation and have made it so that computers could shrink to the sizes we know today. Before, computers took a room because the transistors or vacuum tubes were individual components. Microprocessors unified the technology on one chip while reducing the costs. Microprocessor technology has been the most important revolution in the computer industry in the past forty years, as microprocessors have allowed our consumer electronics to exist.
This new desire for computing portability introduced a number of new challenges. Factors such as cost, weight, power source, screen & keyboard size, overall size, and included software presented great challenges to computer system designers. There is some debate regarding which machine holds claim to being the first portable computer, as portable was a relative term used quite liberally. The earliest portables, while heavy by today’s standards, shared the common characteristic of integrating a keyboard, memory, processor(s), display, and expandability potential into a single unit able to be transported.
The World Turning Digital: computer is seen in virtually all aspects of our lives. From the mobile phones we use, the Television we watch etc. Makes it pretty interesting to found out how this work.
Supercomputers are the supreme machines in the computer world. Supercomputers includes thousands of times the computing power of a desktop and cost several millions of dollars. They fill large halls, which are chilled to prevent their thousands of microprocessor cores from overheating. And they perform billions, or even thousands of billions, of calculations per second.
Almost every device has some type of computer in it. Whether it is a cell phone, a calculator, or a vending machine. Even things that we take for granted most cars since the 1980’s have a computer in it or a pacemaker. All of the advancements in computers and technology have led up to the 21st century in which “the greatest advances in computer technology will occur…” Mainly in areas such as “hardware, software, communications and networks, mobile and wireless connectivity, and robotics.”
In designing a computer system, architects consider five major elements that make up the system's hardware: the arithmetic/logic unit, control unit, memory, input, and output. The arithmetic/logic unit performs arithmetic and compares numerical values. The control unit directs the operation of the computer by taking the user instructions and transforming them into electrical signals that the computer's circuitry can understand. The combination of the arithmetic/logic unit and the control unit is called the central processing unit (CPU). The memory stores instructions and data.
