Communication is almost as important to us as our reliance on air, water, food, and shelter. In todayās world, through the use of networks, we are connected like never before.
Every computer on a network is called a host or end device.
Servers are computers that provide information to end devices:
email servers
web servers
file server
Clients are computers that send requests to the servers to retrieve information:
the web page from a web server
email from an email server.
An end device is where a message originates from or where it is received. Data originates with an end device, flows through the network, and arrives at an end device.
An intermediary device interconnects end devices. Examples include switches, wireless access points, routers, and firewalls.
Management of data as it flows through a network is also the role of an intermediary device, including:
Regenerate and retransmit data signals.
Maintain information about what pathways exist in the network.
Notify other devices of errors and communication failures.

The document describes the Network Monitoring and Performance Verification (PVM) service. PVM provides automated testing and monitoring of key performance indicators for multiple network services simultaneously. It can localize performance degradations to specific network segments. PVM is implemented using open source tools and provides dashboards and reports on service quality. The service benefits network operators and users by verifying service quality. It is integrated with other network management systems using standard interfaces.

The introduction outlines the scope and approach taken in defining terms from mainstream grammar as well as related fields like phonetics and semantics.
Shiva introduces himself at a volleyball camp, providing his name, age, where he lives, education details, subjects he likes, hobbies, favorite color, food, and his purpose for being at the camp. Self-introductions are important for both educational and career contexts. When introducing oneself for an interview, it is important to dress appropriately, greet the interviewers with confidence, and provide details about one's qualifications, strengths, weaknesses, goals and experience. Sample self-introductions are provided for educational and job interview contexts, and tips are given for introducing oneself in a telephonic conversation depending on whether the intended person answers or someone else.
This document outlines secure remote access requirements for the VA. It seeks to provide a structured approach to identifying conditions and functionalities needed from any remote access technology to support VA's core business and healthcare operations. Key requirements include allowing remote access to all clinical, financial and administrative applications from a variety of devices and connections. Remote users must be able to view diagnostic images, transfer data and collaborate with external partners without loss of functionality compared to on-site access. Performance must meet or exceed current VPN standards and support long-term, high data use connections by teleworkers. New users must also be rapidly provisioned to the remote access system.
This document provides a guide to English communication skills including how to ask for information, directions, clarification, and permission as well as how to apologize, agree, disagree, give advice, and make suggestions in a polite manner. It also covers ways to express actions, ideas, preferences and recommendations respectfully. The guide is intended to help with effective interpersonal communication in English.
This document describes configuring and testing extended access control lists (ACLs) on a router to filter traffic between two PCs and a server. It outlines configuring a numbered ACL to permit FTP and ICMP from PC1 to the server, and a named ACL to permit HTTP and ICMP from PC2 to the server. The ACLs are applied to router interfaces and testing verifies only allowed traffic succeeds while denied traffic fails.
Email clients allow users to communicate securely over the internet, share files, back up data, and keep records of business transactions. They support business growth by providing a platform for digital branding and advertising. Email clients make it easy to share different file types and media with remote clients. Data can also be backed up by emailing files to oneself.

This document discusses approaches for using standard Internet protocols for space missions. It summarizes work by the NASA/GSFC Operating Missions as Nodes on the Internet (OMNI) project since 1997 to define and demonstrate end-to-end communication architectures using Internet technologies. The key is selecting appropriate Internet protocols that can support space communication needs while providing interoperability with the terrestrial Internet. Standard protocols are discussed for each layer, including physical, data link, network, transport and application layers. Current and future implementations of these protocols in spacecraft and ground systems are also described.
The document discusses several networking technologies and standards including Ethernet, token passing, wireless, FDDI, and various cable standards. Ethernet using CSMA/CD is currently the most common technology and operates at speeds between 3-1000 Mbps using UTP cable. Token passing networks avoid collisions but have higher overhead. Wireless networks use radio frequencies and CSMA/CA. Fiber Distributed Data Interface (FDDI) uses token passing over fiber optic cable at 100 Mbps. Fast Ethernet includes 100BaseTX at 100 Mbps over CAT5 cable. Gigabit Ethernet includes 1000BaseT at 1 Gbps over CAT5e/6 cable. 10 Gigabit Ethernet allows 10 Gbps transmission over fiber using the 10G
This document discusses network design, architecture, and IP address management principles to support system security and data protection. It advocates for network segmentation through security zones, classification of systems, and private IP addressing to limit lateral movement of threats. The document recommends dividing large networks into separate network domains with defined traffic rules between segments. Criteria-based segmentation and logical/physical isolation techniques can enhance performance and security by restricting access and propagation of faults across network segments.
The document discusses techniques for simplifying and minimizing Boolean functions using Karnaugh maps. It covers representing logic functions as K-maps, grouping adjacent 1s and 0s to simplify expressions, and minimizing functions specified as truth tables or minterms/maxterms.

The document discusses various types of networking media and connectors. It describes RJ-45 connectors as the most common for modern networks. F-type connectors are used for coaxial cable, while fiber optic cable uses several connector types including ST, SC, and LC connectors. Network media can be divided into cable-based options like copper and fiber optic cable, as well as wireless options. Characteristics like speed, length limits, security, and ease of installation vary between media types.
Networks are categorized based on their geographic span. A LAN connects devices within a single location like an office or building using fast networking media over short distances. A WAN spans multiple locations, is generally slower, and more expensive, connecting multiple LANs. A MAN covers an area larger than a LAN but smaller than a WAN, like a university campus or city. Wireless networks use infrastructure topologies with access points to connect to wired LANs, or ad-hoc topologies to directly connect devices without access points. Common wireless standards include 802.11, Bluetooth, and infrared.
