NETWORKING
CHS NETWORKING
Computer network, two or more computers that are connected with one another for the purpose of communicating data electronically... Computer communication may occur through wires, optical fibres, or radio transmissions. Wired networks… Two basic network types are local-area networks (LANs) and wide-area networks(WANs).
A computer network is a digital telecommunications network which allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections between nodes. These data links are established over cable media such as wires or optic cables, or wireless media such as Wi-Fi. Wikipedia
CHS NETWORKING PORT
A network port is a process-specific or an application-specific software construct serving as a communication endpoint, which is used by the Transport Layer protocols of Internet Protocol suite, such as User Diagram Protocol (UDP) and Transmission Control Protocol (TCP).
CHS NETWORKING GATEWAY
A gateway is a node (router) in a computer network, a key stopping point for data on its way to or from other networks. ... In a workplace, thegateway is the computer that routes traffic from a workstation to the outside network that is serving up the Web pages.
CHS NETWORKING DNS
The Domain Name System (DNS) is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities.
CHS NETWORKING PROXY SERVER
In computer networks, a proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers.
CHS NETWORKING SATELLITE PROTOCOL
Protocol. When computers communicate with each other, there needs to be a common set of rules and instructions that each computer follows. A specific set of communication rules is called a protocol.
CHS NETWORKING WIDOWS FIREWALL
Windows Firewall is a Microsoft Windows application that filters information coming to your system from the Internet and blocking potentially harmful programs. ... The first release of Windows Firewall was called Internet Connection Firewall and was released inWindows XP (Service Pack 2).
CHS RJ-45
RJ45 is a type of connector commonly used for Ethernet networking. ... The "RJ" in RJ45 stands for "registered jack," since it is a standardized networking interface. The "45" simply refers to the number of the interface standard. Each RJ45 connector has eight pins, which means an RJ45 cable contains eight separatewires.
CHS RJ-11
Definition of: RJ-11. RJ-11. (Registered Jack-11) Atelephone interface that uses a cable of twisted wire pairs and a modular jack with two, four or six contacts. RJ-11 is the common connector for plugging a telephone into the wall and the handset into the telephone.
CHS UTP CABLE
Unshielded twisted pair (UTP) cables are widely used in the computer and telecommunications industry as Ethernet cables and telephone wires. In an UTP cable, conductors which form a single circuit are twisted around each other in order to cancel out electromagnetic interference (EMI) from external sources.
TELEPHONE
A system for transmitting voices over a distance using wire or radio, by converting acoustic vibrations to electrical signals.
The definition of computer telephony integration (CTI) is a term that can be used to describe any technology that enables computers to interact with telephones. This technology is primarily used in call centers and is often used to describe desktop interactions that improve human agents' productivity.

CHS LOCAL AREA NETWORK GATEWAY/PORT
MODEM
Short for modulator-demodulator. A modem is a device or program that enables a computer to transmit data over, for example, telephone or cable lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves.
ROUTER
A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. ... A packet is typically forwarded from one router to another routerthrough the networks that constitute an internetwork until it reaches its destination node.
CHS PRINTER
A printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printersvary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing.
CHS INFORMATION AND COMMUNICATIONS TECHNOLOGY
NETWORKING SATELLITE PROTOCOL
Satellite Internet is the ability to transmit and receive data from a relatively small satellite dish on Earth and communicate with an orbiting geostationary satellite 22,300 miles above Earth's equator.
Internet over satellite is a high-speed Internet connection made through satellite in order to provide satellite broadband service and two-way access to the global Internet. This is accomplished through low-earth-orbit (LEO) satellites.
CHS NETWORKING GPS
Short for Global Positioning System, GPS is a network of satellites that helps users determine a location on Earth... The picture shows an example of the GARMIN nuvi 350, aGPS used to find locations while driving.
CHS NETWORKING SATELLITE
In other words, it is a telecommunications network provided by orbital communication stations. Signals from these satellites allow a user with a dish to have a high speed internet connection. Satellite Internet access is generally provided either through low earth orbit (LEO) satellites or geostationary satellites.
CHS NETWORKING TRANSCEIVER/RECEIVER
A transceiver is a device comprising both a transmitter and a receiver which are combined and share common circuitry or a single housing. When no circuitry is common between transmit and receive functions, the device is a transmitter-receiver.
COMPUTER HARDWARE SERVICING PHYSICS
Computational physics is the study and implementation of numerical analysis to solve problems in physics for which a quantitative theory already exists. Historically, computational physics was the first application of modern computers in science, and is now a subset ofcomputational science.
Computational science refers to the use of computers, networks, storage devices, software, and algorithms to solve problems, do simulations, build things, or create new knowledge. The figure below shows how Computational Science can be viewed as the intersection of: Computing and networking hardware.
Computational astrophysics refers to the methods and computing tools developed and used in astrophysics research. Like computational chemistry or computational physics, it is both a specific branch of theoretical astrophysics and an interdisciplinary field relying on computer science, mathematics, and wider physics.
The national average mid-career computer science salary is $110,100, according to Payscale. Computer science is one of the highest-paying fields, with an average starting salary of $65,900. Your computer science salary will depend on several factors, including your position, experience, and education.
Salaries. The 33,510 computer scientists working in the United States earned an average $103,160 per year, or $49.59 per hour, as of May 2011, according to the Bureau of Labor Statistics. However, the lowest-paid 10 percent made $56,800, or $27.31, and the highest-paid 10 percent received $151,660, or $72.91.
The dictionary definition of physics is “the study of matter, energy, and the interaction between them”, but what that really means is that physics is about asking fundamental questions and trying to answer them by observing and experimenting.
physics - Computer Definition. The science of matter and energy, and their properties and interactions in fields including mechanics, acoustics, optics, heat, electricity, magnetism, radiation, and atomic and nuclear science. Physics is the science of how things work.
