Application development has become more common in today's world. This is because today people can easily develop applications using different frameworks. A framework is essential for the smooth running of the application. It makes the application development simpler and faster. There are many frameworks like Dot Net for the smooth running of the applications. Even though there are multiple frameworks like Dot Net for developing intuitive applications, the importance of this framework has not yet decreased in the market.
Read the complete article to know the details What is Dot Net? Dot Net framework is a Microsoft software development framework. This framework is responsible for creating applications that run on the Windows platform. The initial version of this framework is released in This framework suits best for form-based as well as web-based applications. This framework supports various languages like Visual Basic and C.
Hence the developers can choose and select the language to develop the application. Dot Net is central to Microsoft's over-arching development strategy. It is so central to the development of the windows platform.
This framework contains a large number of class libraries known as the Framework class library. This programming model provides comprehensive software infrastructure and various services that are necessary to build up robust applications for PC as well as mobile devices. Get more features of. Net: ASP. Net is a part of the Microsoft. Net platform. These applications are the compiled codes written using the extensible as well as reusable components present in the Dot Net framework.
Net is responsible to produce interactive, data-driven applications over the internet. It contains a large number of controls such as text boxes, buttons, and labels for assembling, configuring, and manipulating the code to create HTML pages. This ASP. Net consists of two models. They are: a Web Forms Model: This model extends the event-driven model of interaction to web applications. Here the browser submits the web form to the web server and the server returns the full mark up page or the HTML page in response.
Here all the client-side user activities are forwarded to the server for stateful processing. The server processes the output of client actions and triggers the reactions.
Net framework helps in storing the information regardless of the application state. It consists of page state and session state. The page state is defined as the state of the client. The session state is defined as the collective information that is obtained from various pages the user visited and worked with the overall session state.
Net Model provides various building blocks of ASP. Net pages. It is an object-oriented model that describes the serverside counterparts of all the HTML elements or tags. Server Controls that help in developing complex user-interface. The Dot Net framework is made up of object-oriented hierarchy. Usually, an ASP. Net web application is a combination of multiple web pages.
When the user requests an ASP. Net system. The ASP. Net runtime transforms the aspx page into the instance of the class that inherits from the base class of the Dot Net framework Dot Net Framework Components: This framework is responsible for various services like memory management, networking, type safety. This dot net framework mainly consists of 4 components: a Common Language Runtime CLR : It is a program execution engine that loads and executes the program.
It is responsible for converting the program into the native code. Besides, It acts as an interface between framework as well as operating systems. It does various activities like exception handling, memory management, and garbage collection. Besides, it provides type safety, interoperability, and portability.
It is a set of managed libraries that simplify the common application task such as reading or writing the file systems 2 ASP. Net: It is a web framework designed as well as developed by Microsoft. It is responsible for developing websites, web applications as well as web services.
With this Query language, user can query for data sources with C or the visual basic programming languages. It combines the simplicity as well as the readability of LINQ and provides the power of parallel computing.
Moreover, it is capable of improving and provides the fast speed to execute the LINQ query by using all available computer capabilities. A Dot Net Developer is responsible for designing, tailoring, and developing software applications according to the business needs. In addition to the determination and analysis of prerequisites for the software, he is also responsible for support as well as continuous development. These are the basic responsibilities of the Dot Net Developer.
And it may vary from company to company. In some cases, the role of the dot net developer may also vary from project to project. This is the basic overview of the Dot Net platform. I hope you people have got an overview of. Net and its component. Moreover, you people can get hands-on experience on the. Net framework by live industry experts with live use cases at Dot Net Online Course.
In the upcoming post of this blog, I'll be sharing with you the details of the Dot Net components elaborately. Meanwhile, have a glance at out Dot Net interview questions and get placed in your dream firm.
Some of them were the green screen, terminals, command-line interface, and the graphical user interfaces. Besides, there are some more other methods like application program interface API calls, and web-based management calls.
Among those, the command line interface is capable of performing repetitive tasks quickly and accurately when managing a large number of the system. Hence, Microsoft has introduced shell scripting to meet the needs of the user and ensure that each task is done in the same manner. This article gives you a brief explanation of power shell regarding the need and application in real-time in the IT industry. What is a Power shell?
Power shell is a Microsoft scripting and automation platform. It is both a scripting language and a command-line interface. This platform is built on the. Net framework. This Microsoft platform uses a small program called cmdlets. This platform is responsible for the configuration, administration, and management of heterogeneous environments in both standalone and networked topologies by utilizing the standard remoting protocols.
Once you start working with a power shell, it provides a set of opportunities for simplifying the tasks and saving time. It does this, using a command-line shell and an associated scripting language. At the time of release, this powerful tool essentially replaces the command prompt to automate the batch process and create the customized system management tools. Do you want to expertise on this tool?
Powershell is a popular tool for many MSP because its scalability helps in simplifying the management task and generate insights into devices across the medium or large scale devices. For instance, you can use cmdlets like the Get command to search for other cmdlets. Besides commands like cmd-help responsible for discovering the syntax of the cmdlet, and uses the invoke-command to run the script locally, remotely or even in a batch control Provide Net wide around Powershell enables you to get around software or program limitation especially on a business-wide scale.
For example, PowerShell is responsible for reconfiguring the default setting of a program across the entire network This might be useful if the business wants to roll a specific protocol to all its users using two-factor authentication 2FA or change their passwords for every months.
Scale your efforts across devices: Powershell can be a lifesaver if you want to run scripts across multiple computers, especially if some of them were remote devices. Moreover, this PowerShell is responsible to gather information across multiple devices at once and allows you to install updates, configure settings, gather the information that saves you hours of work and travel time Gain Visibility into information: The advantage of this platform is the accessibility of the computer file system.
Powershell makes it hard to find data in files and the windows registry. Moreover, digital certificates are visible whether it is housed on one computer or many. And it allows you to export the data for reporting purposes. What you can do with the power shell? With the utilization of power shellcode, companies can roll out the changes and updates and can test the GUI.
Besides, it is tightly integrated with most of the Microsoft products. In some cases, products like Microsoft server and office things cannot be done with GUI and only the power shell can do. Microsoft people have designed this tool as an open-source and cross-platform. And it incorporated its capabilities into several interfaces. This power shell has become a robust solution to automate a range of tedious or administrative tasks and then find the filter and export the information about the computer on a network.
It does this by combining the commands called cmdlets and create scripts. Within the power shell, you can leverage the improved power shell access and control over the windows management instrumentation and the component object model to fine-tune the administrative management. This automation tool is greatly helpful for executing a typical management task.
Besides, this power shell includes adding and deleting accounts, editing groups, and creating a list to view specific types of users or groups. Besides, this powerful tool has an integrated scripting environment ISE , a graphic user interface that lets you run commands and create or test scripts. This interface lets you develop the scripts such as command collection, where you can add the logic for execution.
This is particularly useful for system administrators who need to run the command sequences for system configuration. Likewise, there are multiple uses of power shell in the real-time industry. By reaching the end of this article, I hope you people have gained the best knowledge on power shell.
You people can get more practical knowledge on PowerShell taught by real-time experts at power shell online Course. In the upcoming articles of this blog, I'll be sharing the details of more information on PowerShell.
Define what is Active Directory? Answer: Active Directory is a Meta Data. Active Directory is a data base which store a data base like your user information, computer information and also other network object info.
It has capabilities to manage and administrate the complete Network which connect with AD. Answer: Domain local groups assign access permissions to global domain groups for local domain resources. Universal groups grant access to resources in all trusted domains. I am trying to create a new universal user group. Answer: Universal groups are allowed only in native-mode Windows Server environments. Native mode requires that all domain controllers be promoted to Windows Server Active Directory.
What is an IP address? Answer: Every device connected to the public Internet is assigned a unique number known as an Internet Protocol IP address. IP addresses consist of four numbers separated by periods also called a 'dotted-quad' and look something like In computer networking, an Internet Protocol IP address consists of a numerical identification logical address that network management assigns to devices participating in a computer network utilizing the Internet Protocol for communication between its nodes.
The role of the IP address has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there. What is subnet Mask? Answer: A subnet short for "subnetwork" is an identifiably separate part of an organization's network.
Typically, a subnet may represent all the machines at one geographic location, in one building, or on the same local area network LAN.
Having an organization's network divided into subnets allows it to be connected to the Internet with a single shared network address. Without subnets, an organization could get multiple connections to the Internet, one for each of its physically separate subnetworks, but this would require an unnecessary use of the limited number of network numbers the Internet has to assign. It would also require that Internet routing tables on gateways outside the organization would need to know about and have to manage routing that could and should be handled within an organization.
What is ARP? In an Ethernet local area network, however, addresses for attached devices are 48 bits long. ARP provides the protocol rules for making this correlation and providing address conversion in both directions. How ARP Works?
Answer: When an incoming packet destined for a host machine on a particular local area network arrives at a gateway , the gateway asks the ARP program to find a physical host or MAC address that matches the IP address. The ARP program looks in the ARP cache and, if it finds the address, provides it so that the packet can be converted to the right packet length and format and sent to the machine.
If no entry is found for the IP address, ARP broadcasts a request packet in a special format to all the machines on the LAN to see if one machine knows that it has that IP address associated with it. A machine that recognizes the IP address as its own returns a reply so indicating. Define what is Active Directory Domain Services? Define what is domain?
The user need only to log in to the domain to gain access to the resources, which may be located on a number of different servers in the network. Define what is domain controller? Answer: A Domain controller DC is a server that responds to security authentication requests logging in, checking permissions, etc. A domain is a concept introduced in Windows NT whereby a user may be granted access to a number of computer resources with the use of a single username and password combination.
What is a default gateway? What happens if I don't have one? Answer: a gateway is a routing device that knows how to pass traffic between different subnets and networks. A computer will know some routes a route is the address of each node a packet must go through on the Internet to reach a specific destination , but not the routes to every address on the Internet. It won't even know all the routes on the nearest subnets.
A gateway will not have this information either, but will at least know the addresses of other gateways it can hand the traffic off to. Your default gateway is on the same subnet as your computer, and is the gateway your computer relies on when it doesn't know how to route traffic. The default gateway is typically very similar to your IP address, in that many of the numbers may be the same.
However, the default gateway is not your IP address. To see what default gateway you are using, follow the steps below for your operating system. What is a subnet? Answer: In computer networks based on the Internet Protocol Suite, a subnetwork, or subnet, is a portion of the network's computers and network devices that have a common, designated IP address routing prefix cf.
A routing prefix is the sequence of leading bits of an IP address that precede the portion of the address used as host identifier or rest field in early Internet terminology. What is an RFC? Name a few if possible not necessarily the numbers, just the ideas behind them What is RFC ? Efforts are in progress within the community to find long term solutions to both of these problems.
Meanwhile it is necessary to revisit address allocation procedures, and their impact on the Internet routing system. What is CIDR? For example: CIDR addresses reduce the size of routing tables and make more IP addresses available within organizations.
CIDR is also called supernetting. You have the following Network ID: What is the IP range for your network? Answer: You need at least hosts per network. How many networks can you create? What subnet mask will you use? You need to view at network traffic. What will you use? Name a few tools? Answer: Monitoring network traffic tool Q. How do I know the path that a packet takes to the destination?
Answer: use "tracert" command-line Q. What does the ping Answer: The ping command will send roundtrip packets to a destination other PC, router, printer, etc. The The -l is how big the packet should be in bytes. The default is 32, if the -l parameter is not used. And the -n is saying to send, it times. The default is 4, when this parameter is not used. What is DHCP? What are the benefits and drawbacks of using it?
In a networked environment it is a method to assign an 'address' to a computer when it boots up. Benefit: A system administrator need not worry about computers being able to access networked resources Q. Also, DHCP helps prevent address conflicts caused by a previously assigned IP address being reused to configure a new computer on the network. Reduces configuration management Using DHCP servers can greatly decrease time spent configuring and reconfiguring computers on your network.
Servers can be configured to supply a full range of additional configuration values when assigning address leases. These values are assigned using DHCP options. Also, the DHCP lease renewal process helps assure that where client configurations need to be updated often such as users with mobile or portable computers who change locations frequently , these changes can be made efficiently and automatically by clients communicating directly with DHCP servers.
Answer: HCP uses a client-server model. The server database includes the following: Valid configuration parameters for all clients on the network. Valid IP addresses maintained in a pool for assignment to clients, plus reserved addresses for manual assignment.
Duration of a lease offered by the server. The lease defines the length of time for which the assigned IP address can be used. With a DHCP server installed and configured on your network, DHCP-enabled clients can obtain their IP address and related configuration parameters dynamically each time they start and join your network.
DHCP servers provide this configuration in the form of an address-lease offer to requesting clients. Name 2 scenarios.? Answer: Open Windows Components Wizard. Under Components, scroll to and click Networking Services. Click Details. If prompted, type the full path to the Windows Server distribution files, and then click Next. Required files are copied to your hard disk. In the console tree, click DHCP. On the Action menu, click Manage authorized servers.
The Manage Authorized Servers dialog box appears. Click Authorize. Active directory interview questions Q. Similarly, changing authorization rights for a particular user on a group of devices has meant visiting each one and making configuration changes. DHCP integration with DNS allows the aggregation of these tasks across devices, enabling a company's network services to scale in step with the growth of network users, devices, and policies, while reducing administrative operations and costs.
This integration provides practical operational efficiencies that lower total cost of ownership. Creating a DHCP network automatically creates an associated DNS zone, for example, reducing the number of tasks required of network administrators.
This is usually done during the bootstrap process when a computer is starting up. DNS zones — describe the differences between the 3 types. A DNS server resolves a name to an IP address, as stated in an earlier answer, but it can also point to multiple IP addresses for load balancing, or for backup servers if one or more is offline or not accepting connections.
Individual organizations may have their own DNS servers for their local Intranet. Some sites have their own DNS server to switch between subdomains within them. For example, a site such as Blogspot can have subdomains come and go quite frequently.
Rather than force every DNS server to update their own databases whenever someone creates a new blog, Blogspot could maintain their own DNS server to resolve names within the blogspot. The following are the three main components of DNS: Domain name space and associated resource records RRs A distributed database of name-related information. This authoritative information is organized into units called zones, which are the main units of replication in DNS. The following are the three DNS zone types implemented in Windows Standard Primary Holds the master copy of a zone and can replicate it to secondary zones.
All changes to a zone are made on the standard primary. Standard Secondary Contains a read-only copy of zone information that can provide increased performance and resilience. Information in a primary zone is replicated to the secondary by use of the zone transfer mechanism.
DNS record types — describe the most important ones. TTL The length of time used by other DNS servers to determine how long to cache information for a record before discarding it.
For most RRs, this field is optional. This prevents these records from being cached by other DNS servers for a longer period, which would delay the propagation of changes. Class For most RRs, this field is optional.
Where it's used, it contains standard mnemonic text indicating the class of an RR. Type This required field holds a standard mnemonic text indicating the type for an For example, a mnemonic of A indicates that the RR stores host address information.
Record-Specific Data This is a variable-length field containing information describing the resource. This information's format varies according to the type and class of the RR.
Describe the process of working with an external domain name Answer: If it is not possible for you to configure your internal domain as a subdomain of your external domain, use a stand-alone internal domain. This way, your internal and external domain names are unrelated. For example, an organization that uses the domain name contoso. The advantage to this approach is that it provides you with a unique internal domain name. The disadvantage is that this configuration requires you to manage two separate namespaces.
Also, using a stand-alone internal domain that is unrelated to your external domain might create confusion for users because the namespaces do not reflect a relationship between resources within and outside of your network.
