The router chooses the next best link to send packets on to get closer to the destination. Routers use Internet Protocol (IP) packet headers and routing tables, as well as internal protocols, to determine the best path for each packet. Routers use Network Address Translation (NAT) protocol that allow multiple network devices to share a single IP address provided by an Internet service provider (ISP). Routers also implement Dynamic Host Configuration Protocol (DHCP) services for all devices. DHCP assigns private IP addresses to devices.
2.1 Wireless LAN Infrastructure Devices Proper WLAN infrastructure design requires understanding and deploying QoS (Quality of Service) on the wireless network to ensure end-to-end data / video/voice quality on the entire network. Like a traditional wired LAN, WLAN is a grouping of computers and peripheral devices that share a common communications backbone. As per the name itself, a WLAN allows users to connect to the LAN through radio transmission. The below mentioned are the most common components of a WLAN. Access point - The access point is an external device which is used for linking a wireless network to a wired LAN.
It has a series of MANs in those cities, which in turn connect to the LANs in each of the branches. The OB network is adequate but uses very different data link, network, and transport protocols than those used by BEB’s network. Smith’s task is to connect OB’s network with BEB’s network. She has several alternatives. Alternative A is to leave the two networks separate but install a few devices in OB’s headquarters to translate between
k. Preventive controls such as securing wireless access by encrypting wireless traffic and authenticating all devices that try to access the network before allowing them use to the IP address. Detective controls such as an IDS could be used to analyze for signs of attempted or successful
A packet is made of a header to route the packet over the network and thedata. The header contains the source and destination IP addresses the source and destinationports, and other options. IP does not provide guaranteed delivery, duplicate avoidance,integrity, or correct ordering of packets. These properties, if needed, are the responsibilityof higher protocol layers (usually the transport layer with the Transmission ControlProtocol (TCP)). Therefore, it belongs to the best effort of delivery protocols’ category.
Computers allow the client/user to interact with different systems Switches this will send data to multiple computers at the same time. Software Protocols this are set in place so that you can connect devices to the network. Firewall this helps to stop any unwanted attacks on you server/computer. 1.4 Identify the bandwidth limitations of different types of network cabling and connectors With copper cable you have a very limited speed that you will get this can be from 1mb up to 30mb but the speed will also dissipate over the length of the copper cable as well so this will put limitations on the speeds. With fibre cable you will get a constant speed over any distance as the data is transfer via light it will never dissipate and you can get speeds of up to 200mb and is soon to get faster.
Three rules of Netiquette Netiquette is a combination of the words network and etiquette, and is defined as a set of rules for acceptable online behavior. (Anon., 2012) Similarly, online ethics focuses on the acceptable use of online resources in an online social environment. Both phrases are frequently interchanged and are often combined with the concept of a ’netizen’ which itself is a contraction of the words internet and citizen and refers to both a person who uses the internet to participate in society, and an individual who has accepted the responsibility of using the internet in productive and socially responsible ways. So, we are going to explain three rules of netiquette. 1-Respect people's privacy.
The full meaning for the acronym VoIP stands for Voice over Internet Protocol, and it means “voice transmitted over a computer network.” Internet Protocol (IP) networking is supported by any type of network corporate, private, public, cable, and even wireless networks not just the Internet. The corporate sector usually prefers private dedicated networks; telecommuters and home users generally favor broadband (Sinnreich, 2013). Voice over IP is a collection of technologies and protocols that enables communication over the Internet Protocol. It contains all the necessary tools from the analog voice digitization to the data transmission and processing. What does this mean in terms of your actual telephone?
Security/Privacy Besides the obvious advantages in expanding the address space, the following advantages of IPv6 over IPv4: In Fact, almost all the benefits of IPv6 are derived precisely from its packet format and addressing form. Reworked and improved standards will implement at the level of a strong cryptographic protocol (encryption) and many services such as QoS (Quality of Service). QoS support in IPv6 entirely at the network layer. This is extremely important for multimedia broadcasts. Changes made in the IPv6 indicate that he does not just solve the basic problem of a lack of address space, and rebuild the entire structure of the Internet so that it would be more logical and well thought-out.
Cloud. It is basically the collection of computers on the internet that companies are using to offer their services, it is revolutionary storage method for your data. It is convenient and cost effective. It works by storing your files on a server and in the internet somewhere rather than on your local hard drive. This allows you to back up, sync and access your data across multiple devices as long as they have internet capability.
It also helps you get identified on servers, websites, etc. The subnet mask is to hide the individual’s IP into 32 bit numbers. The IP address of default gate is the route for the user’s computer to determine where to send the packets. In this case your gateway will be your router. As for the MAC address it’s the computer’s unique Id on
For this particular task, I will be explaining what key components are necessary for client workstations to connect to a network and how to access network resources. I will be explaining the key features and functions of each of these components in relative detail. Network Devices: These are mechanisms used to connect computers and other electronic devices together so they can exchange and share files or special resources like printers or fax machines used in big organisations. LAN is the main type of network device used by the community. Workstations are special computers designed or technical applications and its meant to be used at one at a time how it works is that it is connected to a local area network (LAN) which is able to run multi user operating system.
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.
Web Development 2 (WD2) 1.1 The hardware components which enable internet access are: Routers – A small device which joins multiple networks together, its entire purpose is to send/route data packets between networks and devices on the network. Routers use wireless and wired technologies to send data packets. Allows multiple computers or other devices join the same network. Ethernet cables – which is normally an RJ-45 cable that connects to the Ethernet card inside the device, the purpose of it is to communicate with the hub/modem/router. Wireless card.
Both types of networks provide network services using operating systems that can communicate with each other through common protocols. Each of these networks enables control of how users and programs get access to resources. Also, clients in a client server network and nodes or hosts in a peer-to-peer network use any combination of desktop, mobile, or tablet operating systems. 2. Discuss the difference between a physical topology and a logical topology.
