Originally supplied as a component of the Option Pack for Windows NT, they were accordingly integrated with Windows 2000 and Windows Server 2003). The current (Windows 2003) version is IIS 6.0 and includes servers for FTP (a software standard for transferring computer files between machines with widely different operating systems), SMTP (Simple Mail Transfer Protocol, is the de facto standard for email transmission across the Internet) and HTTP/HTTPS (is the protected version of HTTP,the communication protocol of the World Wide Web) .
This type of network has decentralized management of its administration, system performance, resources and security. Also, in a peer-to-peer network clients share their resources directly with each other, and each user has a local account that only allows access to the network from one of its computers. Additionally, in a peer-to-peer network nodes or hosts are
Understanding networking is a fundamental part of configuring complex environments on the internet. This has implications when trying to communicate between servers efficiently, developing secure network policies, and keeping your nodes organized. Every location or device on a network must be addressable. This is simply a term that means that it can be reached by referencing its designation under a predefined system of addresses. In the normal TCP/IP model of network layering, this is handled on a few different layers, but usually, when we refer to an address on a network, we are talking about an IP address.
This is different from client side scripting however, since to be a server side script the data must be executed on the web server side, compared to the Client side scripts which are executed by the user’s browser. Different Web Server Scripting Languages: There are many different server side scripting languages which can be used on the web servers, these include: ASP: This is Microsoft’s web server scripting product which will commonly only run on a Windows based server. Files have the file extension of .asp which stands for Active Server Pages. Finally VBScript are used within ASP pages. ASP.net: ASP.NET is an open-source server-side web application framework designed for web development to produce dynamic web
1. Describe the functions of the kernel, service, and command layers of an OS. The kernel basically acts as the interface between hardware and applications. The kernel is also known as the engine or core of an OS, the outermost part of an operating system that interacts with user commands. Some of the kernel’s tasks are resource allocation, process management, memory management, input/output device management, and security management.
‘Chubby’ is a unified lock service created by Google to synchronize client activity with loosely coupled distributed systems. The principle objective of Chubby is to provide reliability and availability where as providing performance and storage capacity are considered to be optional goals. Before Chubby Google was using ad-hoc for elections, Chubby improved the availability of systems and reduced manual assistance at the time of failure. Chubby cells usually consist of chubby files, directories and servers, which are also known as replicas. These replicas to select the master use a consensus protocol.
Hadoop  is an open source implementation of MapReduce programming model which runs in a distributed environment. Hadoop consists of two core components namely Hadoop Distributed File System (HDFS) and the MapReduce programming with the job management framework. HDFS and MapReduce both follow the master-slave architecture. A Hadoop program (client) submits a job to the MapReduce framework through the jobtracker which is running on the master node. The jobtracker assigns the tasks to the tasktrackers running on many slave nodes or on a cluster of machines.
Limited permissions:-In SQL, we are going about as servers or databases, permitting the client can restrain testimony. For instance, we dole out db_datareader client part, and after that the client can execute certain put away systems permit. (b) Five key areas Database monitoring:- This is fundamentally to screen and examine database movement and takes and records exchange, for instance don 't believe any local evaluating. This guarantees high server accessibility. Other than utilizing it to examine patterns.
A Linked List is made up of a chain of nodes, linked lists are slow when it comes to random access however they are fast for inserts and deletes anywhere in the list as you can update a few next and previous pointers of a node. A Linked List is a common way of storing an array, a major benefit of a Linked List is that you don’t specify a fixed size therefore the more elements you add to the chain, the bigger the chain gets. This is ideal for the storing of data within our program as we have a take orders method which will add an order to the array each time. An alternative to a Linked List is an Array List. Linked Lists and Array Lists both implement a list interface.
A three-tier configuration could be a web-enabled business application. The client (tier-one) would be a web browser on your computer, the application server (tier-two) is the web server that hosts the site or application, and data server is the tier-three system that is accessed by the tier-two server, not the tier-one client. Whereas, a two-tier system the client software is loaded on the client computer when opened the client software will retrieve and process the data from the data server. A fat client is loaded locally on a computer, where a thin client is
In this first screenshot, I basically opened command prompt and search for ipconfig. Within those instructions, I have gather information that you can evidently see in the screenshot, such as my desktop’s name, wireless LAN adapter, Ethernet adapter LAN, and other connections running. Without typing ipconfig /all in command prompt, people wouldn’t be able to tell a lot from just using a sniffer like Wireshark. For instance, within the content of the screenshot you can tell I have Comcast due to the evidence (hsd1.va.comcast.net) from Connection-specific DNS Suffix. Another thing that can be evidently seen in the screenshot, is my IPv6 and IPv4 address which allows me connect/create more TCP/IP address within the Internet.
Devices like a hub or a switch; has much less capabilities as they are only capable of performing basic network functions. For example, a hub is usually used to transfer data between computers and network devices, but however, it doesn’t analyse or do anything with the data it contains. In the other hand, routers can analyse the data being sent and transferred over a random network, then change how it is packaged and once it has done that it can send it to another network. There are two different types of a routers out there, they are: the router and the wireless router. In the example picture above, the router allows all the computers and other network devices to access the internet.
S-CSP: Storage provider is nothing but kind of an entity which makes available storage services of data inside a public cloud. S-CSP offers outsourcing data services and then it stores that data in support of a users of the data. To trim down the cost of storage, the Service Providers eradicates the storing of an unneeded data by using Deduplication technique or methods whereas it also maintains only distinctive form of data rather keeping all the files having similar content. Users: The owners or users are those who would like to outsource their data in public cloud to S-CSP then it access that stored data later whenever required. In this system of storage, in support of Deduplication method, a user uploads only unique single data copies/files although it is impossible for them to upload any duplicated data files.
