Computers are related to networks due to the fact that computers need to be able to communicate to one another on the same network. Computers come in different sizes and processing levels. Computers are needed in any wireless network. Price varies from $299.99 to $4,999.99 Tiger Direct (n.d.) A firewall is considered a device that connects or is built in the software and directly to a network or computer with Windows XP and higher operating systems. A firewall used security purpose that only allows trusted sources to access the network or the other way around.

List and explain the three things that have to work together in order for most computers to perform useful functions. Hardware – External and internal physical components App Software – Programs that are loaded onto computers to perform specific functions Operating System – Computer programs that manage the hardware of a computer 2. List and explain the two general categories of application software. Business/industry software – software that is designed for use by a specific industry such as medical practice management tools, educational tools, or tools designed for use by law profession for example CAD etc.
Citrix EdgeSight a) Introduction. 1. It provides the real time visibility necessary to test, deliver and monitor the performance of web, desktop, and virtualized apps with the best user experience. 2. Monitor and measure end-user experience of virtualized applications- Real time alerting and access to session level performance information provides administrators with detailed user specific data for fast identification of application, system and network problems in a single console.

More specifically, software that performs some useful function for a user. Computer network: A combination of many components that work together so that many different devices can communicate. Computer networking: The gerund form of the term computer network. Email: Electronic mail.
Multiprogramming is a method of running several different programs in a computer at the same time 6) What is a process? Many definitions have been given for the term process including, - A program in execution - An instance of a program running on a computer -The entity that can be assigned to and executed on a processor -A unit of activity characterized by a single sequential thread of execution, a current state, and an associated set of system resources 7) What is the difference between windows Windows7 and Linux with regard to address space and processor support? The address space, is not really different, it's dependent on the processor of the machine Linux will run on any processor that;s relatively modern (arm, sparc, alpha, mips, ia64, i386, PPC) Windows 7 will only run on i386 ( x86 or
The network layer then uses its protocol (IP) and translates that www.yahoo.com into an IP address. The network layer is also in charge for determining the best route through the network in order to get to the IP address destination. The data link layer is, unlike the other two which are virtual, a physical address with is permanently encoded to a device through its network card. The data link layer is a unique identifier to each computer in a network. Thus a MAC address is the only address that will always remain the same, transport and data layer address can change depending on the network.
NT1210 – Introduction To Networking LAB 7.3 Communications of Paths Exercise 7.3.1 Creating a cloud computing would be the best option this way the all parties can communicate. This would allow the Headquarters to place the order to Manufacturing to start the order. Then Manufacturing can place any supply orders need to Foundry to create the ordered product. Also will allow the Shipping Site A to notify Shipping Site B of the status on the product allowing Shipping B to also communicate with Shipping Site C. features & benefits * Service Level Agreement (SLA) across the complete network * Managed Security which allows management of all content in and out of the network, which in effect outsources all your security to. * Cloud Computing: offer a wide range of "Infrastructue as a Service" Cloud computing services within the network all at a fixed low cost, and with little or no capital outlay.
Question 1 Grade Average= (67.4 + 86.4 + 79.2 + 80 + 68.2) / 5 = 76.24 Question Score= (0.15 * 76.24) = 12 Question 2 Grade Score= 55% Question Score= (0.10 * 55) = 5.5 Question 3 A VPN (virtual private network) is a way of creating a secure connection over the public internet say from a teleworkers province, to their employer’s headquarters. The user is authenticated and the sensitive data being sent through the VPN tunnel is encrypted. This therefore makes using VPN over the internet, similar to having a dedicated layer 2 leased line. Cisco SSL (Secure Socket Layers) is used to encrypt the data before it is sent through the VPN tunnel. It uses a variety of algorithms to provide authenticity and integrity of the data, and uses session keys.
With those thoughts in mind, exposing the lab to these risks must be approached carefully and with the knowledge that will not be too expensive but very effective. Even though the network will encompass a lab environment, the security implementation should be treated as enterprise would treat it. To begin with, the decision to address the many possible security risks will be to implement a Raptor firewall. The major cost areas will come from software, hardware, personnel, training, and some extras to provide very stable platform. Software will include the Raptor Firewall NT v6.5 with virtual private network (VPN module) and unlimited mobile users at $17,579, plus a standard maintenance contract at a value of $1,194.
Under large bussiness corporations, the scope expands to include other factors such as safe-guarding business legal and transactional interests. The integral part of AUP is the cde of conduct the the users need to display when using the internet or internet. Code of conduct stipulates that the users have to what extent to use the network, the language that uses when they are online especially on social sites and avoid illegal activities that the organisations doesn’t allow. The company or the organisation offering internet have the consequences on the violation of AUP. This may include
