These machines so really to help us when we need a cash money, and now we’ll be easy to found these machine at most supermarkets, convenience stores and travel centers. Did you have think about the process that makes your funds available to you at an ATM on the other side of the country?
ATM is a simply a data terminal with two input and four output devices. Like any other data terminal, the ATM has to connect to, and communicate through, a host processor. The host processor is analogous to an Internet service provider (ISP) in that it is the gateway through which all the various ATM networks become available to the cardholder.
Most host processors can support either leased-line or dial-up machines. Leased-line machines connect directly to the host processor through a four-wire, point-to-point, dedicated telephone line.
Leased-line ATMs are preferred for very high-volume locations because of their thru-put capability, and dial-up ATMs are preferred for retail merchant locations where cost is a greater factor than thru-put. The initial cost for a dial-up machine is less than half that for a leased-line machine. The monthly operating costs for dial-up are only a fraction of the costs for leased-line.
The host processor may be owned by a bank or financial institution, or it may be owned by an independent service provider. Bank-owned processors normally support only bank-owned machines, whereas the independent processors support merchant-owned machines.
Settlement Funds
When a cardholder wants to do an ATM transaction, he or she provides the necessary information by means of the card reader and keypad. The ATM forwards this information to the host processor, which routes the transaction request to the cardholder’s bank or the institution that issued the card. If the cardholder is requesting cash, the host processor causes an electronic funds transfer to take place from the customer’s bank account to the host processor’s account. Once the funds are transferred to the host processor’s bank account, the processor sends an approval code to the ATM authorizing the machine to dispense the cash. The processor then ACHs the cardholder’s funds into the merchant’s
bank account, usually the next bank business day. In this way, the merchant is reimbursed for all funds dispensed by the ATM.

Almost all computer users know the term Memory and Disk Space, but many of them mistakenly interpret these two terms, many of them interpreted as a long-term memory and short-term memory.
Memory or RAM stands for Random Access Memory and is known as volatile or temporary memory types. This can be used to store new information, just like you when trying to remember something for a minute.
On the computer, this is biasda happens when you save the document before closing it. When you save a document, its contents are transferred from RAM (temporary memory of the computer) into the hard disk (long-term memory of the computer). If this process is disrupted by power failure, cancellation by the user, or some other things, the contents of this document are “missing”. This is similar to what happened when we were sorting important, keeping valuable information from our short-term to long-term memories.
Disk Space is a space on your hard drive, where the applications you use on your computer is stored. When you open or run the program, this program will take from the disk into your computer RAM, and the program instructions and then run from RAM. Computers can only process the instructions in RAM. Therefore, for each program to be executed, must first be loaded from the disk into your computer’s memory. RAM is also used when we create documents and pictures or other files.
RAM is volatile memory, would “wipe out” when we turn off the computer or if there is a power failure. If the information is “erased” in RAM, this is not saved and the computer does not have a record of the existence of such information ..
Every time you type a new document, whatever you type at first stored in RAM. But, since RAM is volatile or temporary, if you want to keep what you’ve typed, you need to save your document. When you remove the Save command in your application, the information you have that type of RAM will be transferred to the hard drive and stored in a file.
As you can see, the memory (or RAM) and disk space related. They depend on each other for your computer to operate properly. When you use a computer, application and transfer of data from disk to RAM when needed. This data is then manipulated in RAM. The contents of the RAM should be kept back any changes back to the hard disk. If not, anything in RAM is not saved will be lost.
Data or files on a disk can be deleted, too. When a user “delete” a file, whether it is operating system files or files from your favorite application programs such as MS Word, iTunes, or a graphics program used to edit images, files are not really erased. Instead, your computer simply marks the space available and the program or remove material that is inaccessible to users.
When the computer needs the space program or document removed once claimed, then the space is replaced with the new information. However, if the files deleted the old space is never needed by the computer, the material remains on the hard drive. This realization has given birth to a forensic computer science as the material is obtained if you have the proper equipment and be able to access the hard drive storage space with special programs aimed to retrieve deleted files.

In the first this year Hasbro has come out with the new radical redesign of the famed Monopoly board game.
First, the world is round. Hasbro ditched the four-corners look for a pizza-like circle. The stops on this journey are the same, but each location now comes as a radial wedge. Houses and hotels basically match older versions, but the game replaced its pewter character pieces with plastic tokens. Farewell, little doggy, shoe, and top hat.
Second, no more paper bills. Monopoly’s trademark funny money has gone digital. A computer banker sits in the center of the “Revolution” board. Players spread the money around by using novelty debit cards. Good news for parents: No more picking up colored bills all over the house. Bad news for older siblings: No more sneaking extra cash under the table. Some special editions of Monopoly already come with faux ATMs – it’s only a matter of time before kids figure out new ways to “game” the system.
Third, inflation hit Monopoly-ville. As you pass Go, you do not collect $200. Instead, you earn $2 million. Hasbro says all of the prices have been jacked up to better represent today’s financial market.
Finally, the sound of money. As in good movies, music will punctuate the action. Clips of pop songs, such as Rihanna’s “Umbrella,” Daniel Powter’s “Bad Day,” and Beyonce’s “Crazy in Love,” will ring out during the game.

The development of static and dynamic RAM integrated circuits followed swiftly in the late 1960s and early 1970s. Compared to the relays and vacuum tubes used for computer memory function prior to the development of the magnetic core memory models, the advancement created a more user friendly experience as well as an increase in the amount of memory a computer could be expected to produce. This precursor to the common personal computer revolutionized the technological world since it made it possible to begin to see the advantages of the computer for personal use instead of being seen and used only in business operations. The computer systems of today boast a hierarchy of memory that includes CPU registries, SRAM caches, external caches, DRAM, and swap space among others. This is often referred to as RAM, but it actually defies the original concept of true random access memory and does not hold the same intent as the original magnetic core memory from which RAM was born. The methods utilized by the pool of memory in today’s computers often sequence through various subsystems with different access times in layered sequential order to allow the illusion of instantaneous response times. Generally, the computer accesses its memory in order of speed with the slower forms of memory being the last to be drawn from when a command is given to the computer. RAM now has methods of upgrading that allow for even greater memory capacity if there is a need to change the amount of RAM a computer has based on the amount of RAM used by the operator on average, these are usually in the form of DRAM and come in the form of memory modules. A few sticks of chewing gum are comparable in size to the memory modules in terms of physical size. These modules can be replaced quickly in the case of damage or should the amount of memory need to be increased again at a later date. Small amounts of RAM, most commonly SRAM, are also found in other locations on the computer, such as the mother board or the hard drive. Developers are currently investigating the possibility of non-volatile RAM. This would be another huge step in computer memory as these new forms of RAM would allow for the preservation of data upon the loss of power. Currently, RAM is a volatile memory form and will lose information if an interruption of power occurs. Carbon nanotubes offer promising results in this field of RAM development, but no non-volatile RAM has been released for public use yet. All of the developing technologies under this direction of RAM are pre-beta stage at present. MRAM has seen some success with the release of several chips that have undergone extensive testing. The core technology of MRAM depends upon the concepts of the magnetic tunnel effect and is promising to turn the world of computer memory onto the pathway of the future as a result. In 2004, Solid state drivers became available. Bases on flash technology, these drivers have a capacity exceeding 150 GB. These drivers also have speeds that far exceed the speed of traditional disks. In short, this means that the lines between RAM and disks have blurred and there is less difference between the two in performance. With each passing year, memory capacity grows. New technologies revolutionize the way we think of computer memory and how we use that memory once it becomes available. It is expected that computer memory will only continue to increase and evolve as our world becomes more technologically advance.

Maybe almost all computer user has had experience of having their PC crash or hang, and sometime that problem make your data gone, so maybe you will lost your email, your mail contact address, your document and all the important file. So here the option for your consideration, to prevent your data being lost :
1. Check the components hardware. Occasionally a computer data recovery effort will not even be required at all. While it might seem like a hard drive has crashed, another component may be to blame. For example, the mother board or power supply might be faulty. Therefore, it makes sense to check these things before writing off the hard drive. If it’s unclear that these parts might be to blame, enlisting professional help might be in order.
2. Repair Operating System. If a your computer will still not boot up, computer data recovery in this case might require repairing or replacing corrupt core operating system files. To do this, follow to repair the OS.
3. Data recovery software programs. If the operating system or hardware issues are not blame for the failure and the computer will still boot up, a computer data recovery disk might help restore missing or accidentally deleted files. There are programs available from computer shops and online that are specifically designed to help with data recovery efforts.
4. Professional data recovery services. At now many companies that specialize in computer data recovery. They have the necessary hardware and software tools required to be able to recover files that individuals will not have at home or in the office. While these services can be costly, I’m sure that if your data is restored, you’ll agree that the expense is worth it. Beyond regular computer professional services that specialize in data recovery, computer forensics companies might be able to help out in extreme cases (for example, computers damaged in the case of fire or flood).
Computer data recovery is possible even when a hardware crash or failure has occurred. While the results will vary depending on the severity of the crash, the cause and the methods used, it is possible to retrieve files and data off of even the most severely damaged of hard drives.
