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.
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.
Each configuration has its advantages and disadvantages; complexity or flexibility, cost (hardware and software), performance, scalability and user load. We have software that is designated with a site license, meaning that we can run unlimited instances at our physical address. We have other software packages that are licensed to an individual user’s device. Multiple variables must be considered in deciding how software is loaded and presented to the user base. Each software package has it individual licensing and system requirements.
Several components required to implement VPN depends on the type of VPN i-e. Remote Access VPN, or site-to-site VPN. Network design is crucial to decide the throughput, choice of devices and number of users. There are two types of networks where VPN is needed to implement. 1. Site-to-site VPN—is provides connection between branches i-e. LAN-to-LAN VPN with their own internet instead of dedicated leased lines.
I will be able to develop the network architecture for various clients and also install, deploy, maintain, troubleshoot product and test services according to their needs. Client requirements may be at local, wide area or an organization level. This will help me to interact with the end user and will help me know their demands. Interaction will be among the users, infrastructure vendors like Internet service providers, software vendors who together make up a communication network and integrate services in them and keep the communication system
3. In a domain network one or more computers are servers so that network administrators are able to control the security and permissions for all computers also
In developing a database, one of the first things one must know is how the database(DB) will be used within the organization. Seconda,y what type of data will be required to develop the database and how it will enhance productivity and reliability to the organization. All the information is gathered in the first phase of the database life cycle, which is planning. In the planning phase, you are gathering information on the need, cost and feasibility of the database within the organization. Also within this phase you would look to see if there are databases within the organization that can meet the requirements.
Therefore, the database can be any type such as SQL, Not Only SQL (NOSQL), or other. Observation_4: The CSP needs to apply a virtualization technology on storage resources to serve CSUs’ demands efficiently. Therefore, a
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.
Data Communication protocols are formal descriptions of data formats and rules in which the more than one system exchanges data /information. The protocols cover various issues such as authentication, error detection and correction. Popular network communications protocols used are the TCP/IP and User Datagram Protocol (UDP), while TCP is connection oriented once a connection is established, UDP connectionless Internet protocol. The model for information exchange includes the data source which generates the data to be transmitted, Transmitter which converts the data into transmittable signals, Transmission system which carries the data, Receiver which converts received signals into data and Destination which takes incoming data. TCP/IP uses
You need to understand your existing network infrastructure to determine how well it can meet the needs of your deployment goals. By examining your existing infrastructure, you identify if you need to upgrade existing network components or purchase new network components. You should build up a complete map of the existing network by covering these areas: 1. Physical communication links, such as cable length, grade, and so forth 2. Communication links, such as analog, ISDN, VPN, T3, and so forth, and available bandwidth and latency between sites 3.
It has also shown me that ipconfig can also display IP address, default gateways, adapters like Bluetooth, and subnet masks. Although the TCP/IP are generated into a simpler form for the human to understand, the information off this project can relapse the information we learned from Hands-on Activity 4A. For example, I remembered that TCPs can help the user establish a network connection to another company ’s DNS. I also found out that each Physical address is uniquely made for each user.
In this case, the security configuration for each shared directory can be implemented using group policies. Concisely, groups define collections of machines that have the same level of access to a specified network resource, and they offer some extra control to such resources. This technique will allow the system administrator for the CWE systems to configure which users/groups have access to what resources (Help.ubuntu.com, 2015). Handling printing in the CWE systems network
Quiz#2 . With respect to the RPC mechanism, consider the “exactly once” semantic. Does the algorithm for implementing this semantic execute correctly even if the ACK message back to the client is lost due to a network problem? Describe the sequence of messages and discuss whether “exactly once” is still preserved.
