What is data storage? the terms data objects, variables, and constants concerning data storage?
In a computer, the data is stored in memory, registers, and external media.Generally, all these devices have an approximately simple structure as a sequence of bits arranged into bytes or words. However, data storage of the virtual computer for a programming language influence to carry a more complex organization with arrays, stacks, numbers, character strings, and multiple forms of data existing at multiple points during the implementation of a program. It is acceptable to use the term data object defines the run-time arranging of one or more elements of data in a virtual computer.Any data objects that continue during the ...
Read MoreWhat are the attributes of programming languages in compiler design?
There are various attributes of programming language in compiler design which are as follows −Simplicity and Clarity − Few languages such as Basic, Algol, and Pascal in the past were purposely created to simplify clarify of expression. Basic, for example, had a very small instruction set. Algol 60 had a publication language that supports a standard structure for typesetting programs that occurred in published journal articles. Pascal was specially created as a teaching language, with features that simplified the teaching and learning of structured programming principles.Readability − An essential principle for determining a programming language is the ease with which ...
Read MoreWhat are the different benefits of using programming languages in compiler design?
There are the following benefits of programming languages which are as follows −To improve your ability to develop effective algorithms − Some languages support features if they are used appropriately, which will be useful to the developer. But if used inappropriately, it can cause waste in a huge amount of computer time or lead the developer to tedious logical errors. Recursion is a convenient programming feature that, when accurately used, enables the direct performance of simple and efficient algorithms. When used inappropriately, it can generate an extreme raise in execution time.To improve the use of existing programming language − By ...
Read MoreWhat is the difference between Computer Architecture and Computer Organization?
Computer ArchitectureThe architecture defines those attributes of the system apparent to the programmer or those attributes that directly force the program’s logical execution. It manage with the functional behavior of the computer system view by the user.Computer Architecture manages with the system’s programming part, including the multiple bits can define the several data types, input-output methods, approaches for addressing memory, and the computer’s instruction set. The implementation of any program is influenced by these qualities of architecture. The change in a bit or size can lead to a different result for the programmer.Computer OrganizationComputer organization can study the basic computer ...
Read MoreWhat is Myrinet Clos Network?
Myrinet is a high-performance, packet-communication, and switching technology. It was produced by Myricom as a high-performance alternative to conventional Ethernet networks. Myrinet switches are multiple-port components that route a packet entering on an input channel of a port to the output channel of the port selected by the packet.Myrinet switches have 4, 8, 12, 16 ports. For an n-port switch, the ports are addressed 0, 1, 2... n - 1. For any switching permutation, there may be as many packets traversing a switch concurrently as the switch has ports. These switches are implemented using two types of VLSI chips such ...
Read MoreWhat is Ethernet?
Ethernet is a packet-switched LAN technology introduced by Xerox PARC in the early 1970s. Ethernet was designed to be a shared bus technology where multiple hosts are connected to a shared communication medium. All hosts connected to an Ethernet receive every transmission, making it possible to broadcast a packet to all hosts at the same time.Ethernet uses a distributed access control scheme called Carrier Sense Multiple Access with Collision Detect (CSMA/CD). Multiple machines can access an Ethernet at the same time. Each machine senses whether a carrier wave is present to determine whether the network is idle before it sends ...
Read MoreWhat are Clusters?
A cluster is a collection of stand-alone computers connected using some interconnection network. Each node in a cluster could be a workstation, personal computer, or even a multiprocessor system.A node is an autonomous computer that may be engaged in its private activities while at the same time cooperating with other units in the context of some computational task. Each node has its input/output systems and its operating system.When all nodes in a cluster have the same architecture and run the same operating system, the cluster is called homogeneous, otherwise, it is heterogeneous. The interconnection network could be a fast LAN ...
Read MoreWhat is the Client-Server Framework for Parallel Applications in Computer Architecture?
Parallel applications can be designed using the client/server model. A client may divide a big application into several smaller problems that can be processed by multiple servers simultaneously. All the servers compute the solution to their respective problems and send their results to the client.The client assembles the results from each server and outputs the final result to the user. The client acts as the master (supervisor) while the servers act as the slaves (workers) in the master-slave (supervisor-workers) model as shown in the figure. The steps are taken at the client and each server is summarized as follows.Client (Supervisor)Client ...
Read MoreWhat are the routing potential problems in Computer Architecture?
Several possible problems can result from the use of certain routing mechanisms in message-passing systems. These include deadlock, livelock, and starvation, which are as follows −Deadlock − When two messages each hold the resources required by the other to move, both messages will be blocked. This is called a deadlock. It is a phenomenon that occurs whenever there exists a cyclic dependency on resources. Management of resources in a network is the responsibility of the flow control mechanism used. Resources must be allocated in a manner that avoids deadlock.Livelock − Livelock describes a situation in which a message keeps going ...
Read MoreWhat is the Routing in Message Passing Networks in Computer Architecture?
Routing is defined as the techniques used for a message to select a path over the network channels. Formally speaking, routing involves the identification of a set of permissible paths that may be used by a message to reach its destination, and a function, h, that selects one path from the set of permissible paths.A routing technique is said to be adaptive if, for a given source and destination pair, the path taken by the message depends on network conditions, such as network congestion.Routing techniques can also be classified based on the method used to make the routing decision as ...
