Node
- A node is any device connected to a computer network. Nodes can be computers, personal digital assistants (PDAs), cell phones, or various other network appliances. On an IP network, a node is any device with an IP address.
Client
- A computer connected to a shared resource server. Is a software program that is used to contact and obtain data from a Server software program on another computer, often across a great distance. Each Client program is designed to work with one or more specific kinds of Server programs, and each Server requires a specific kind of Client. A Web Browser is a specific kind of Client that works with Web Servers.
Server
- a computer, or a software package,that provides a specific kind of service to client software running on other computers. The term can refer to a particular piece of software, such as a WWW server.
Hub
- A network hub is a hardware or device that allows multiple computers to connect together to form a single network segment. A network hub is a critical component for allowing more than one computer to connect with other computers. Network hubs are common in home offices and businesses.
Network Interface card (NIC)
- Also called adapter cards. Serves as the interface between the computer and the network cable for sending and receiving data.
Network Operating System (NOS)
- A special application that allows computers and other devices on the network the ability to communicate and accept and receive information. Windows95, the Mac OS, and Windows NT are operating systems.
Host Computer
- computer connected to the Internet or any type of data network. It hosts information resources as well as application software for providing network services.Every host is a physical network node.
Network Manager
- is a software utility that predominately aimed to simplify the use of computer networks such as Linux operating system.

Sockets
- Computer sockets are the built-in interfaces on motherboards that accept various hardware components. It uses pin grid array (PGA) where its pins connects to holes.
Chips
- A computer chip is a small electronic circuit, also known as an integrated circuit, which is one of the basic components of most kinds of electronic devices. Computer chips are small and are made of semiconductors that is usually composed of silicon, on which several tiny components including transistors are embedded and used to transmit electronic data signals.
Slots
- An opening available on the motherboard where you can insert printed circuit boards to add additional functionality to a computer system. Sometimes the openings/ holes on the rear of the case (where all the computer components are installed) are referred to as expansion slots.
Bus Lines
- pathway that transits the data between a computer's central processing unit (CPU) and its random-access memory (RAM).
Graphic Card
- Also known as video card, video adapter, graphics-accelerator card, display adapter which all is an expansion card. It is a hardware installed to generate and render images to display on the computer’s monitor.
Sound Card
- Otherwise known as an audio card it is an expansion board that facilitates the input and output of audio signals. It enables the computer to output sound through speakers connected to the board, to record sound input from a microphone connected to the computer, and manipulate sound stored on a disk.
Modem Card
- A modem card allows users to connect to the Internet using a network. It can be wireless (external USB card) or it can be installed inside of a user's PC. Wireless modem cards allow Internet access by communicating with a router that is connected to a user's PC.
Network Interface Card
- hardware that is added to the PC to allow it to communicate with the network. The card attaches to a cabling that is also connected to a router. This is the central point for network connectivity, and it allows the two computers to share files and data.
Plug and Play
- It is an ability of a computer to detect and configure a new piece of hardware automatically, without the requirement of the user to physically configure the hardware device. For example, inserting a mouse to a USB port, it will work instantly.
Serial Port
- is a computer physical interface that has 9-pin connectors that relay information, incoming or outgoing, one byte at a time. Each byte is broken up into a series of eight bits, hence the term serial port.
Parallel Port
- Serial ports differ from 25-pin parallel ports in that the parallel ports transmit one byte at a time by using eight parallel wires that each carry one bit. With data traveling in parallel, the transfer rate was greater. A parallel port could support rates up to 100 kilobytes per second, while serial ports only supported 115 kilobits per second (kbps).
Universal Serial Bus Port
- Is an external serial interface used on computers and other digital devices to transfer data using a USB cable. USB port allows us to connect computer peripherals such as mice, keyboard, video camera and other external devices to transfer files.
FireWire Port
- Firewire ports are forms of a serial port that make use of FireWire technology to transfer data rapidly from one electronic device to another. The firewall technology has the ability to transfer data in a relatively fast rate which can reach up to 400 Mbps. FireWire technology also creates a connection between two independent devices, such as connecting a digital camera to a mini printer and print the photos using its original file, without uploading it to a hard drive and then initiating a printing process.

Business-to-consumer (B2C)
- Business-to-consumer is selling individual products to individual buyers, usually on cash payment basis; retailing
- That is, activities of businesses serving end consumers with products and/or services. An example of a B2C transaction would be a person buying a pair of shoes from a retailer. The transactions that led to the shoes being available for purchase, that is the purchase of the leather, laces, rubber, etc. as well as the sale of the shoe from the shoemaker to the retailer would be considered (B2B) transactions.

E-commerce
- eCommerce, includes of the buying and selling of products or services over electronic systems such as the Internet and other computer networks. e-commerce is used transferring funds electronically, supply chain management, Internet marketing, processing online transaction , electronic data interchange (EDI), inventory management systems and automated data collection systems.
Internet security suite
- provides the utilities such as antivirus, personal firewall, spam blocker and popup blocker for maintaining the security of a Windows PC from malicious online threats that may harm your computer.
Javascript
- Javascript is a scripting language developed by Netscape to enable Web authors to design interactive sites. Although it shares many of the features and structures of the full Java language, it was developed independently. Javascript can interact with HTML source code, enabling Web authors to spice up their sites with dynamic content. JavaScript is endorsed by a number of software companies and is an open language that anyone can use without purchasing a license.
Plug-in
- a plug-in consists of consists of a computer program that interacts with a host application usually to provide a certain, normally a specific, function "on demand". Add-on is often considered the general term comprising plug-ins, extensions, and themes as subcategories

A technical writer traditionally take technical or complex information and put it in a form that a non-technical or non-expert audience can understand. They must analysis the information and come up with ways to make it more presentable and understandable to individuals not trained in the field. To do this they may start by gaining an understanding of the audience. They then conduct research, interview specialists, and produce and edit the document. Then they add accompanying information, such as tables or illustrations. However, their job has evolved to include many other tasks than just translating instruction manuals. They may also involve in web designing and teach.Software engineer
