CAT5- Networking twisted pair cabling standard used to support 100MHz = 100 Mbps speeds.These cables are slower compared to modern-day hardware requirements. So, you should use this type of Cable only if you have older hardware that demands outdated hardware.CAT5e one of the most popular cabling types of ethernet cable used for deployments because of its ability to support Gigabit speeds at a cost-effective price.can support up to 100MHz = 1,000 Mbps / 1 Gbps.CAT6High performance UTP that can support up to 10 Gbps and frequencies of up to 250Mhz = 1,000 Mbps / 1 Gbps CAT6aethernet cable supports bandwidth frequencies of up to 500MHz = 10,000 Mbps / 10 Gbps = 10Gbps CAT7600Mhz = 40,000 Mbps/ 40 Gbps = 10Gbps offers extensive shielding to decrease signal attenuation.CAT82GHz = 25 Gbps or 40 Gbps = 40Gbps this reduces power consumption and is designed for bandwidth-intensive data center applications.What manages the operations of the network interfaces? Network software and its configurations three major categories of networkspersonal area network (PAN) local area network (LAN) wide area network (WAN) Personal Area Network (PAN)is normally used for short-range communications, within a few feet, such as wireless headphones to a smartphone or a wireless mouse to a PC.Local Area Network (LAN)consists of a collection of computers in a single building or building complex. For example, the computers in a manufacturing building.wide area network (WAN)links systems over a greater distance, including machines on the opposite sides of the world.How else are networks classified?Other classifications of networks consider whether the network's internal workings are based on designs that are in the public domain (open network) or on designs owned or controlled by third parties (closed or proprietary networks).Open Network designsFreely circulated and are often more popular than proprietary designs that are restricted by license fees and contracts. The internet is an example of this type of design.TCP/IP ProtocolOpen collection of standards that governs communication over the internet Four common topologiesbus, star, ring, and mesh

Bus NetworkMachines are connected to a common communication line Star networksa single machine serving as a central point to which all others are connected.Ring networksconnect directly to each other as a peer.Mesh networksconnects every device in a network to every other device; mesh networks enable redundancy while also introducing significantly more network traffic.Which network topology best handles downed links without losing connectivity between devices?Bus Ring Mesh Star Mesh Which type of network is used to interconnect devices in a single office or building?

WAN PAN SAN LAN LAN Why are protocols important for networks? What's the purpose of protocols?Networks rely on protocols to govern communication. Without protocols, the computers in a network might try to transmit messages at the same time or fail to provide needed assistance to other machines. Using protocols, vendors are able to build products for network applications that are compatible with products from other vendors.Interprocess communicationallows the activities or processes on different computers within a network to coordinate actions and complete tasks.Types of Interprocess Communicationclient/server model peer-to-peer model

The client/server modelis a popular convention used for interprocess communication. The basic roles played by the processes are categorized as either a client making requests or a server satisfying client requests.Peer-to-peer (P2P)is another model for interprocess communication. In this model, processers both request and provide service to each other.example of client/server modela single printer available to all computers. The printer (also known as the print server) is the server, and the machines are clients requesting printed documents.examples of peer to peer modelInstant messaging and interactive games played by users on multiple machines are both examples of the P2P model.Distributed systemssystem that executes software as processes on more than one computer.Cluster computinguses many independent computers to provide computation or services comparable to those of a larger machine. Cluster computing provides high availability as it is likely that at least one computer in the cluster will be able to answer a request even when others in the cluster are unavailable or broken down.Grid computingis a type of distributed system that is more loosely coupled than clusters but still works together as a system to complete large tasks. Grid computing typically includes specialized software to make it easier to distribute the workload and data among the machines in the grid.Cloud computingprovides large pools of shared computers that can be allocated to clients as needed. Cloud computing provides reasonable guarantees for reliability and scalability while raising concerns about security and privacy.A network is a collection of two or more connected devices that can communicate with one another transmission mediathe lowest level of components in a network = The radio waves or the physical system (cable) that transports data on a network. There are two types: wired and wireless.Wired Transmission Mediaex: twisted-pair cable, coaxial cable, fiber-optic cable.Restricts signal so that it is contained within a cable and has to follow the same path.

Wireless Transmission Mediaex: Microwave, Satellite, Radio.

Based on radio signals of various frequencies; no physical transmission medium
