...Task 2 Advantages of ecommerce Having a business open 24/7 I have been asked the discus in detail the impacts and negative impacts of an e-commerce business; I am going to first discus the impacts of an e-commerce business running 24/7. There are many impacts with having an 24/7 e-commerce online business, I first looked at the website tokokoo.com (online) that it mention that the advantage of it being opened 24/7 is that people all over the world can purchase what the e-commerce website is selling, this impacts your business as all parts of the world we be buying your products and services at all times ‘Even while you’re sleeping, your customers can visit your store and browse your products and place their orders’. Another advantage of it being opened 24/7 is that you can purchase items/services anytime you want this is a good impact new targets markets can be made which is for the people who work long hour days which means they are too busy in the day because there working which means they do not have time for shopping in the day, this impacts your business and achieves more customers which means you will sell more. Includes that customers will be satisfied as they can purchase items from their own home. A disadvantage of having a 24/7 business is that you will have to pay more for staff to keep this e-commerce business operated at all times, people who would be operating the website are not on a normal wage like a shelf stacker it is far more. The negative impact...

...File C5-207 July 2007 www.extension.iastate.edu/agdm Elasticity of Demand E lasticity of demand is an important variation on the concept of demand. Demand can be classified as elastic, inelastic or unitary. An elastic demand is one in which the change in quantity demanded due to a change in price is large. An inelastic demand is one in which the change in quantity demanded due to a change in price is small. The formula for computing elasticity of demand is: (Q1 – Q2) / (Q1 + Q2) (P1 – P2) / (P1 + P2) If the formula creates a number greater than 1, the demand is elastic. In other words, quantity changes faster than price. If the number is less than 1, demand is inelastic. In other words, quantity changes slower than price. If the number is equal to 1, elasticity of demand is unitary. In other words, quantity changes at the same rate as price. Close substitutes for a product affect the elasticity of demand. It another product can easily be substituted for your product, consumers will quickly switch to the other product if the price of your product rises or the price of the other product declines. For example, beef, pork and poultry are all meat products. The declining price of poultry in recent years has caused the consumption of poultry to increase, at the expense of beef and pork. So products with close substitutes tend to have elastic demand. Figure 1. Elastic demand Elastic Demand Elasticity of demand is illustrated in Figure 1. Note that a change in price...

...is lower than that of its trading partner. 1.1 Technology and markets The Ricardian model assumes that production uses only 1 input (labor), with constant returns to scale. This assumption means that the technology in each country and each sector is entirely determined by the labor requirement per unit of output. The other assumptions are that (a) labor moves freely between sectors within a country, but (b) labor cannot move between countries. Assumption (a) implies that in a particular country, the wage must be the same in both sectors; assumption (b) means that the wage need not be the same (and typically is not the same) in the two countries. In addition, all agents are price takers, i.e. there is perfect competition. In my example, the unit labor requirements are unit labor requirement Corn (good 1) US Canada au = 1 1 Umbrellas (good 2) au = 1 2 ac = 3 ac = 6 1 2 Table 1, Labor requirements 1 (Corn is good 1, umbrellas are good 2.

...Chapter 1 Microeconomics of Consumer Theory The two broad categories of decision-makers in an economy are consumers and firms. Each individual in each of these groups makes its decisions in order to achieve some goal – a consumer seeks to maximize some measure of satisfaction from his consumption decisions while a firm seeks to maximize its profits. We first consider the microeconomics of consumer theory and will later turn to a consideration of firms. The two theoretical tools of consumer theory are utility functions and budget constraints. Out of the interaction of a utility function and a budget constraint emerge the choices that a consumer makes. Utility Theory A utility function describes the level of “satisfaction” or “happiness” that a consumer obtains from consuming various goods. A utility function can have any number of arguments, each of which affects the consumer's overall satisfaction level. But it is only when we consider more than one argument can we consider the trade-offs that a consumer faces when making consumption decisions. The nature of these trade-offs can be illustrated with a utility function of two arguments, but is completely generalizable to the case of any arbitrary number of arguments.1 An advantage of considering the case of just two goods is that we can analyze it graphically because, recall, graphing a function of two arguments requires three dimensions, graphing a function of three arguments requires four dimensions, and, in general, graphing...

...Chapter 6: CPU Scheduling • • • Basic Concepts Scheduling Criteria Scheduling Algorithms Operating System Concepts 6.1 Basic Concepts • Maximum CPU utilization obtained with multiprogramming. • CPU–I/O Burst Cycle – Process execution consists of a cycle of CPU execution and I/O wait. – Example: Alternating Sequence of CPU And I/O Bursts – In an I/O – bound program would have many very short CPU bursts. – In a CPU – bound program would have a few very long CPU bursts. Operating System Concepts 6.2 1 CPU Scheduler • The CPU scheduler (short-term scheduler) selects from among the processes in memory that are ready to execute, and allocates the CPU to one of them. • A ready queue may be implemented as a FIFO queue, priority queue, a tree, or an unordered linked list. • CPU scheduling decisions may take place when a process: 1. Switches from running to waiting state (ex., I/O request). 2. Switches from running to ready state (ex., Interrupts occur). 3. Switches from waiting to ready state (ex., Completion of I/O). 4. Terminates. • Scheduling under 1 and 4 is nonpreemptive; otherwise is called preemptive. • Under nonpreemptive scheduling, once the CPU has been allocated to a process, the process keeps the CPU until it releases the CPU either by terminating or by switching to the waiting state. Operating System Concepts 6.3 Dispatcher • Dispatcher module gives control of the CPU to the process selected by the short-term scheduler;...

...CPU SCHEDULINGCPU scheduling in UNIX is designed to benefit interactive processes. Processes are given small CPU time slices by a priority algorithm that reduces to round-robin scheduling for CPU-bound jobs.The scheduler on UNIX system belongs to the general class of operating system schedulers known as round robin with multilevel feedback which means that the kernel allocates the CPU time to a process for small time slice, preempts a process that exceeds its time slice and feed it back into one of several priority queues. A process may need much iteration through the "feedback loop" before it finishes. When kernel does a context switch and restores the context of a process. The process resumes execution from the point where it had been suspended.Each process table entry contains a priority field. There is a process table for each process which contains a priority field for process scheduling. The priority of a process is lower if they have recently used the CPU and vice versa.The more CPU time a process accumulates, the lower (more positive) its priority becomes, and vice versa, so there is negative feedback in CPU scheduling and it is difficult for a single process to take all the CPU time. Process aging is employed to prevent starvation.Older UNIX systems used a 1-second quantum for the round- robin scheduling. 4.33SD reschedules processes every 0.1 second and recomputed priorities every second. The round-robin scheduling is accomplished by the -time-out mechanism, which tells...

...Supply, Demand and Equilibrium in Linear Equation The quantity demanded is the amount of a good that consumers want to buy at a given price, holding constant all other factors that influence purchases. The demand function shows the mathematical relationship between the quantity demanded , the price of the product, and other factors that influence purchases. A demand curve plots the demand function, again holding constant other factors. The quantity supplied is the amount of a good that firms want to sell at a given price, holding constant all other factors that influence firms’ supply decisions. The supply function shows the relationship between the quantity supplied, the price of the product, and other factors that influence the number of units supplied. An equilibrium exists if no market participant wants to change its behavior. In a market, equilibrium occurs at the price and quantity where the demand curve and the supply curve intersect. Example Problem: :SUPPLY AND DEMAND .AT $1.40 PER BUSHEL,THE DAILY SUPPLY FOR OATS IS 850 BUSHELS AND the daily demand is 850 bushels.when the price falls to $1.20 per bushel,the daily supply decreases to 350 bushels,and the daily demand increases to 980 bushels.assume that supply and demand equation are linear A-find the supply equation.
