...Task 1: Speech is the ability humans have developed to communicate between themselves with the sound produced by their mouth and nose. There are two types of speech sounds: The voiced and unvoiced one. A voiced sound is created when air pass through our vocal cord in direction of the mouth. This air vibrates in a certain frequency, normally between 50 and 400 Hz that produces the sound heard and desirably understood by the receiver ears. This frequency is controlled by varying the shape of the air channel, as changing the mouth position or the tongue, working as a filter, allowing the desired frequencies for the expected sound to pass; and by the speaker age and sex. The unvoiced speech are created by making air go through an opening, not vibrating the vocal cords, and, consequently, not been as...

...Q1. (i) I have depicted the 3 naturally accruing isotopes of hydrogen. Hydrogen-1, sometimes known as Protium or just hydrogen, hydrogen-2, also known as Deuterium and finally Hydrogen-3, which is also known as Tritium. Although each isotope has a different number of neutrons; 0, 1 and 2, respectively. This has no impact on their chemical properties. But, it does however affect the physical properties. Namely their mass. Whereas Hydrogen-1 has an atomic mass of 1amu, Hydrogen-2 has an atomic mass of 2, due to the presence of a neutron in addition to the proton within the nucleus. And Hydrogen-3 has an atomic mass of 3amu as a result of another additional neutron. Each isotope also differs in its’ nuclear binding energy, this is a result...

... The project is the basis of the following theory: VLAN is a logical network, provides logical segmentation of network. Virtual LANs separate layer2 switch into multiple-broadcast domains. Each VLAN is its own individual broadcast domain, i.e. IP subnet. Here groups of ports or individual ports can be assigned to a specific VLAN and Only the ports which are belonging to the same VLAN can freely communicate; ports assigned to separate VLANs require a router to communicate, Broadcasts from one VLAN will never be sent ports belonging to another VLAN. A layer two switch that supports VLAN is not always necessarily a layer three switch, in addition to supporting VLANs, must also be capable of routing, and caching IP traffic flows. Layer 3 switches allows IP packets to be switched as opposed to routed, which reduces latency. VLANS work by handling tags to the network packets creating the functionality and aspect of network traffic, which is physically on one and only one network but acts as if it divided between two separate networks. Thus, VLAN can have network applications separate despite being connected to the same physical network and without requiring multiple sets of cabling all and networking devices. Otherwise, an external router is required for inter-vlan communication. In the LAN environment broadcast domains are divided by the VLANs. When a host in one VLAN have to communicate with a host in another VLAN the traffic has to route between them, this kind of routing is called...

...receive signal. Transport layer 4, which is the segment . Protocol working from this layer are TCP and UDP, TCP is for reliable connection, to make sure the datagrams arrives at the destination and UDP is for unreliable , unlike TCP using UDP there will not be any confirmation source like TCP, when the latency (signal) is bad you would use UDP. The network layer which is layer 3, it provides connection between host on different network, the datagrams on layer 3 are called packets where IPv6 and IPv4 begins process. Next, is layer 2 which is data connection which is known as data link, this is where ethernet will be operating. Also Mac addresses also know as hardware addresses, the layers on layer 2 are called frames. Lastly, Layer 1 they are for devices such hubs,connectors and cables. The physical layer describes all electricals and physical specifications for devices. The data are called bits. When troubleshooting it will always start at the physical layer. TCP TCP which stand for Transmission Control Protocol, it is a protocol of which works with reliability, it guarantees delivery of data from sender to receiver. TCP works at the transport layer which is layer 4. TCP three-way handshake, these are the steps on how it works it establishes the route of device is present on the network, 2.

...Task 1.1 and 1.2, Significant features of Local Area Networks. A Describe in detail peer to peer. Peers are computer networks that are connected to each other through the internet. Files can be shared directly between systems without the need of a central server, which makes each computer on a p2p system its own client as well as a file server. A P2P (peer to peer) network requires only that you have an internet connection and P2P software such as, Kazaa , LimeWire, or bearshare. When a P2P is connected it allows you to search for files on other peoples computers, while at the same time allows other users on the network to access yours that are typically assigned onto a single folder that you have designated to share. One of the main upsides to a p2p network is that it does not need an expensive server as each individual computer acts as one. The user sets their own privacy settings as to which files are accessible to others. When a computer fails it does not affect the other parts of the network, though the files from the non-functioning computer are inaccessible. The p2p as with all networks has its downsides. There is no central backup for files, and files are difficult to locate if the computers owner has no logical filing system. The network requires a joint effort from each individual user to ensure that viruses are not introduced into the entire network. There is essentially no security other than user permission settings. Describe client server: Client/server, is...

... Bridge A software/hardware that have job as a media to connect separate networks together so they can communicate each other called as a bridge. For example, there a two networks. The first one the device are connected by wireless technology and other by cables. The device which using wireless only can communicate with other wireless and the wired device only can communicate with wired also. So, all device can communicate with each other using a network bridge. It also determines a data packet are allowed or not to the other part of the Ethernet segments. Router Router is a device that allows the similar network to interchanges data packets between them. Similar network like same servers, workstations and protocols. Routers forward data based on information at layer 3. Nowadays, every home share a broadband internet connection by using a wireless routers. Also, people can give password to their routers to manage the traffic and forward to the correct computer only. Router also have other advantages like can connect to different WAN (Wide Area Network). So, we can find the usage of router to WAN of a network or larger networks. DSL Modem Internet is a computer network which have part to connect one device to another device base on TCP/IP (Internet Protocol).

...Name: MUTAIB HAIL ALSAHLI ID: 120004631 Answer, Question number 1, Before we talk about the differences there are Some people who may easily forget the fact that the USB Type-C and USB 3.1 are different from each other, considering the fact that both cross platforms were developed by the USB Forum (USB-IF) simultaneously, USB Type-C is a physical connector and USB 3.1 is a technology standard. Compatible devices can transfer data at a very high speed of up to 10GB per second.USB 3.1 standard allows for high-speed data transfer, but other devices such as tablets and smartphones might not transfer data that fast's Type-C and USB 3.1 are often confused with each other. The main difference between the two is that USB Type-C is developed to support USB 3.1 signals. Some devices might have Type-C connectors which only support the older USB standards such as USB 2.0 and USB 3.0. With more and more devices such as the new Lumia, Nexus are getting equipped with USB Type-C connectors combined with USB...
