∙ 11y agoStatic RAM holds onto its data as long as the chip is under power, why dynamic RAM holds on to data only for a relatively short time, and needs constant refreshing.
Dynamic RAM is much cheaper and can be produced with much higher capacity (because each bit requires fewer transistors, thus less space on the chip) than static RAM.
Modern PCs and other high performance computing equipment typically uses dynamic RAM. Static RAM is used where very high RAM capacity is not needed and the cost for dynamic RAM refreshment is prohibitive, as often is the case in embedded devices.

∙ 14y agoThe reason it is called Dynamic RAM is because it has to be refreshed, an electric pulse gives it power then it needs to do it again.Again since bits are as charge stored in capacitors they tend to leak.
If it is not refreshed then any data in RAM will be lost hence its Volatile. For example if you are typing a document and have not saved any of it yet to your hard drive then it is still in RAM, if the power goes out then you will lose all of the information in RAM.
DRAM is less expensive than SRAM.
Its slow.
it has simpler construction.
Found in main memory
Static RAM does not have to be refreshed, it will hold data regardless if the computer is turned off or on. hence its nonvolatile.now why isn't all RAM static you ask?
Because static RAM is very expensive and it would put the cost of a computer out of the reach of most people.
Bits are stored as on/off switches so no charge leak.
Its faster.
Found in cache

∙ 8y agoThere's no such thing as static or dynamic memory. Memory is either statically-allocated (at loadtime) or dynamically-allocated (at runtime), but regardless of how it is allocated it's the exact same type of physical memory and therefore operates at exactly the same speed.
The difference is merely in when the memory is physically allocated. Statically-allocated memory is allocated at loadtime so the memory is immediately accessible at runtime. Dynamically-allocated memory is allocated at runtime and each allocation therefore has a runtime cost before it can be accessed. Once allocated, there is no difference in performance.
Given that each request for memory from the system has a runtime cost, it makes sense to keep those memory allocations to a minimum. This can be achieved by dynamically reserving memory and allocating your dynamic resources within that memory rather than constantly asking for new memory.

∙ 12y agoNo, in general it is the other way around. static ram is faster then dynamic ram because SRAM is made up of flipflops .it desn't require refreshing like dynamic ram.........

Difference between Dynamic binding and message passing in oop?
Message to method bindingA question of whether a message should bind toa method in the class to which the reference variable pointing to the receiver was declared to be an instance of (static binding), ora method in the class to which the receiver is an instance of at run-time (dynamic binding).Dynamic bindingin the context of OOP typically refers to the binding of methods to messagesmethods varying dynamically entails much of the power of the OO approachmain source of power in an OO languagesearch for method (code body) to bind to a message starts from the class to which the receiver currently (i.e., at run-time) is an instance of, and and proceeds up the class inheritance hierarchy from there (static binding initiates the search from the class to which the reference variable pointing to the receiver was declared to be an instance of)if no method found anywhere, a run-time error (method not found) is reported and this is typically the only error in a Smalltalk program ever detected and reportedexample: Mammal m; Cow c; if (user input) m = new Cow; // if static binding used, run method in class Mammal bound to run message here // if dynamic binding used, run method in class Cow bound to run message here m.run else c = new Cow; c.runWhy dynamic binding?`to allow software systems to be more easily extended during both development and maintenance' [COPL] p. 461allows dynamic polymorphism, consider sorting (written in a general way)obviates need for abstract classes (e.g., Fruit class, peel method)while other forms of dynamism in languages tend to be compromise efficiency in the run-time system, dynamic binding involves little overheadDynamic vs. static bindingadvantages of each?disadvantages of each?Message to method binding in languagesSmalltalk dynamic by defaultby sending a message to super we can initiate the search (for the method to bind to the message) in the parent class of the class to which the sender belongs (i.e., like sending a message to self with a different entry point for the search (not quite static binding))Java and Eiffel dynamic by defaultin Java, preface method with final qualifier to prevent any subclass from overriding itin Eiffel, preface method with frozen qualifier to prevent any subclass from overriding itC++ static by default (why?)preface method with virtual qualifier for dynamic binding; the search for the method to bind to the message starts in the class which defines the method prefaced with the virtual qualifier and proceeds down the inheritance hierarchy from there to the class to which the receiver object belongsObjective-C, Modula-3, Python, and Ruby use dynamic binding for all methodsSimula, C# and Ada 95 use static binding by default and support dynamic binding as an optionDynamic binding ambiguityDo not confuse dynamic binding of messages to methods with dynamic allocation and deallocations of objects.Smalltalk: manual dynamic allocation, automatic deallocationJava: manual dynamic allocation, automatic deallocationC++: manual dynamic allocation, manual deallocation
What is the difference between Late binding and early binding?
Early binding. The type of the instance is determined in the compile time. It follows that the static (declared) type of the pointer or reference is used. This is the default for all methods in C++, C, or Object Pascal.Late binding. The type of the instance is determined in the run time. It follows that the actual type of the instance is used and the method of this type is called. This is always used for the methods in Java. In C++, the virtual keyword denotes the methods using the late binding.Late binding gives the class polymorphic behavior. On the other hand, late binding is less effective than early binding, even though the difference may be negligible. (In C++ on PCs, the difference between the late and the early binding is usually one machine instruction per method call.)Any method that might be overridden in any of the derived classes should use the late binding.Note:In C++ and other OOP languages in which the late binding must be declared, the classes containing at least one virtual method are called polymorphic classes. Classes without any virtual method are called non-polymorphic classes. In languages like Java, where all the methods use late binding by default, all the classes are polymorphic.

Which computer should i go with to learn IT and Programming?
If you plan to follow a course of lessons, then that will almost certainly say what software you need and that will dictate the hardware required. If you're planning to "self-teach" - nothing wrong with that! - then I'd start with what you have and what you want to achieve. If you already have a PC with at least 4GB RAM and an I3 processor (or better) then you could start with Microsoft's Visual Studio Community products which are free and are stripped down versions of the full Visual Studio (VS) software that Microsoft themselves use to write software. There are many books published about using VS. Note that the hardware requirements Microsoft specify for VS are quite low; in practise development machines should be the faster the better and also benefit from at least two screens - it makes debugging applications much easier to have one screen running the application and the other running Visual Studio.

The difference is dynamic pressure vs. static pressure.
Does c and c plus plus support static or dynamic binding?
Yes and no. Static vs dynamic binding is not a C or C++ language issue; it is a linker issue. If you link with a .lib file that contains stubs for run-time loading, then the called routine will not be loaded until it is invoked, and it will not be made a part of the load module.
What is a static HTML file?
Static HTML vs Dynamic HTML. Static HTML is a web document(s) that show the same information for all users. It can be updated from time to time but shows the same information to each and every user. Dynamic HTML is a web document that shows different information per user due to factors such as a search. This web page will vary depending on information passed to it.

What is diffirence between static and dynamic friewall?
Static vs Dynamic Filtering -- Static (constant and unchanging) packet filtering offers security against novice hackers. You can configure the filtering rules when you install a firewall to filter based on source/destination IP addresses. This sets up a static filter. But static packet filtering does not have the intelligence to selectively open and close ports; it can either open all the non-private ports or close them all. If all ports are kept open, an intruder can break in; if all ports are closed, the firewall becomes obtrusive to the users on the network. (To see why ports are opened, see the section on FTP Security, below.) Dynamic filter
What are the classification of operation research model?
Operations research models are typically classified based on their structure and nature, with common classifications including deterministic vs stochastic models, static vs dynamic models, and discrete vs continuous models. Deterministic models assume perfect information and known inputs, while stochastic models factor in uncertainty and randomness. Static models are based on a single period of time, while dynamic models consider multiple time periods. Discrete models involve integer or binary decision variables, whereas continuous models use real-valued variables.
What is difference between static vs dynamic testing?
Static vs. dynamic testingSoftware testing is an investing conducted provides stockholders with information about the quality of product or service under test. Software testing can also provide an objective, view of the software to allow the business to appreciate and understand the risk of software implantation. Test techniques include, but are not limited to the process of executing a program or application with the intent of finding software bugs. There are large number of approaches of software testing.Reviews & inspections are called as static testing, whereas actually executing programmed code with a given set of test case is referred to as dynamic testing.Static testing can be omitted, and in practice often is.Dynamic testing takes place with the program itself used. Dynamic testing begin before the program is complete its execution in order to particular sections of code are applied to discrete function or modules. Typically techniques for this are using stubs / drivers or execution from a debugger environment.A static testing involves verification whereas dynamic testing involves validation. Together they help to improve software quality.Other methods of software testing:The box approachVisual testing

What is dynamic routing?
Routing refers to the process of moving packets of information across a network. Static and dynamic routing are the two types of routing algorithms used for this transfer of information.The term routing encapsulates two tasks. These tasks are deciding the paths for data transferred and sending the packets on these paths. The routing is a process that is a function carried out at layer 3 of the OSI reference model. The routing algorithm decides the output line to transfer the incoming packets. The routing algorithms are based on the routing protocol that uses metrics to assess whether a particular path is the optimal path available for transfer of the data packets. The metrics used for evaluating the paths are bandwidth, delay and reliability. The routing algorithms use these protocols to determine an optimal path from the source to the destination. The routing tables maintain all the information related to routing. There are various routing algorithms and depending on these routing algorithms, the information stored in the routing table varies. Every router has its own routing table and it fills this table with the required information to calculate the optimal path between the source router and the destination router. To understand the basic points of static vs dynamic routing, let us get to know what are routing tables.Routing tableA routing table is a document stored in the router or a network computer. The routing table is stored in the form of a database or is simply a file stored in the router. The data entered in the routing table is referred to when the best possible path to transfer information across two computers in a network is to be determined. The two classifications, viz., static and dynamic routing, are based on the way in which the routing tables are updated every time they are used. The routers in which the data is stored and updated manually are called static routers. On the other hand, the routers in which the information is changed dynamically, by the router itself, are referred to as dynamic routers. Let us compare the two types of routing algorithms based on the static and dynamic routing algorithm used, in the static vs. dynamic routing section given below.Static Vs. Dynamic RoutingStatic routing manually sets up the optimal paths between the source and the destination computers. On the other hand, the dynamic routing uses dynamic protocols to update the routing table and to find the optimal path between the source and the destination computers.The routers that use the static routing algorithm do not have any controlling mechanism if any faults in the routing paths. These routers do not sense the faulty computers encountered while finding the path between two computers or routers in a network. The dynamic routing algorithms are used in the dynamic routers and these routers can sense a faulty router in the network. Also, the dynamic router eliminates the faulty router and finds out another possible optimal path from the source to the destination. If any router is down or faulty due to certain reasons, this fault is circulated in the entire network. Due to this quality of the dynamic routers, they are also called adaptive routers.The static routing is suitable for very small networks and they cannot be used in large networks. As against this, dynamic routing is used for larger networks. The manual routing has no specific routing algorithm. The dynamic routers are based on various routing algorithms like OSPF (Open Shortest Path First), IGRP (Interior Gateway Routing Protocol) and RIP (Routing Information Protocol).The static routing is the simplest way of routing the data packets from a source to a destination in a network. The dynamic routing uses complex algorithms for routing the data packets.The static routing has the advantage that it requires minimal memory. Dynamic router, however, have quite a few memory overheads, depending on the routing algorithms used.The network administrator finds out the optimal path and makes the changes in the routing table in the case of static routing. In the dynamic routing algorithm, the algorithm and the protocol is responsible for routing the packets and making the changes accordingly in the routing table.Nowadays, the static routing is seldom used. With the technological advancements, the dynamic routing is used to route the packets in the network, efficiently. Thus, the above algorithm explains routing, routing tables and static vs dynamic routing.
