TECHNO LINGO
Technology is the making, modification, usage, and knowledge of tools, machines, techniques, crafts, systems, methods of organization, in order to solve a problem, improve a preexisting solution to a problem, achieve a goal or perform a specific function.
Information technology (IT) is concerned with the development, management, and use of computer-based information systems.

Processor - The chip that handles all PC (i.e. Desktop or Laptop PC) decisions. Everything a computer does is controlled by the Processor and the slower or faster this is, the slower or faster the the PC will be.
RAM - Random Access Memory is the short term memory the PC uses to quickly access information and programs. The more RAM you have, the faster the PC will run
HDD - The Hard Disk Drive is a physical component inside the PC that stores long term information such as documents or media files.
Resolution - A measurement of the horizontal and vertical pixels displayed that determines the sharpness of the PCs screen.
Optical Drive - Drive (CD, DVD or Blu-ray) used to access information via optics (a laser and a lens)
Graphics Adapter - a PC part that deals with all graphics and outputs them to the monitor. Sometime there is a separate GPU (Graphics Processing Unit), While other times it is build into the main processor.
Super TFT - Thin Film Transistor is a glossy highly reflective coating that is added to the PC screen to add vibrancy and colour, improving video quality.
HDMI - High Definition Media Interface is a digital connetion that attaches the PC to an HDTV or external display and makes it posible to watch HD content on a second display.
BLUETOOTH
Bluetooth lets you beam data from one device to another over a short distance. It’s found in most mobile phones, letting you swap photos or videos with others or print directly to a Bluetooth printer. It’s also behind the wireless controllers for PlayStation 3 and Wii.
GPS
The Global Positioning System is the technology behind satnav (satellite navigation) devices. Switch on your navigator and it’ll search for satellites in the sky above. Once it’s locked on to the signals of three or more orbiting spacecraft, it can triangulate its position. In perfect conditions it has an accuracy of within three metres.
WI-FI
Wireless technology or WiFi, lets you connect your computer to a network without a cable. That network could be one at home or the internet. New games consoles like the PlayStation 3 and Wii have Wi-Fi built in, so they can get online too. Older equipment like the Xbox 360 and some older computers need special adapters to make them Wi-Fi enabled.
HSDPA
High Speed Downlink Packet Access is the complicated name for fast internet to you mobile phone. It works along side 3G networks to vastly improve the download speed of your mobile when using the internet. Currently it runs at 1.8mbps in most countries, although some networks have used it to transfer data at 14.4mbps. That’s fast enough to download a whole movie in less than 10 minutes.
MEGAPIXELS
The number of mega pixels in a camera typically determines its quality. The more mega pixels the bigger and more detailed the image produced. Although it’s important to pick a camera with a good quality lens too. Some mobile phones boast impressive mega pixel figures but don’t have a focus lens so if the subject’s too close or too far away your photo will look blurry.
RESOLUTION
This is the number of pixels displayed by a screen. Generally, the higher the resolution the better, although the size of the screen is also important. For instance a two inch screen with a resolution of 240x320 pixels will be worse than a one inch screen with the same resolution. That’s because the same number of pixels are spread over a larger space, so they are bigger and images look less detailed.
HI-DEF
High Definition, or HD is the standard term for high definition TV or games. It simply means much better quality images and comes in two varieties, 720 and 1080. These numbers refer to the number of lines on screen. 1080 represents the best quality or ‘full HD’ as some call it, as there are more lines and more detail in picture. As if this wasn’t enough, there are two types of both varieties – interlaced or progressive, denoted by an ‘i’ or ‘p’ following the numbers. Interlaced HD refreshes odd lines first, and even lines second, while progressive HD updates them all at once. Some say progressive HD is better, although in reality they both update faster than the human eye, so it’s almost impossible to tell the difference

Push email is a method of having email received for a user on a server automatically forwarded to a mobile device. This works by keeping an active connection open between the mobile device and the server so that the server can notify the mobile device immediately when new email has arrived. In a typical non-push (pull) scenario, the mobile device would poll the server at some user specified time interval (such as every hour) and ask the server if any new email has arrived. If new email arrives even a second after the server is polled, it will sit there waiting until the next time that the mobile device checks for mail. Push technology is also often used for non-email data such as contacts and calendar appointments, as well.
Your phone sucks a lot of power constantly communicating with email servers. Try turning off push email and see how many more precious hours you’ll get out of your phone on a single charge.
IMAP (Internet Message Access Protocol) is
richer in functionality than POP and is designed to allow clients to access and
manage mailboxes on the server as if they were local. IMAP is a much more
complex protocol than POP, with less client support. IMAP4 is the latest
implementation of IMAP.
Although the messages reside on the mail server clients that support IMAP can
manipulate these messages in many ways.
Some users like to keep their e-mail online indefinitely for future searching. In such cases, IMAP offers the flexibility of selectively retaining messages, whereas POP does not.
RSS - “Really Simple Syndication’’ or “Rich Site Summary’’ are terms used to describe a number of XML-related aggregation technology versions that grew out of a project at Netscape geared to manage news headlines for portal web sites.
What does RSS stand for? There's a can of worms. RSS as introduced by Netscape in 1999 then later abandoned in 2001 stood for "Rich Site Summary." Another version of RSS pioneered by UserLand Software stands for "Really Simple Syndication." In yet another version, RSS stands for "RDF Site Summary."

KVM Switch
Stands for "Keyboard, Video, and Mouse switch." As the name implies, a KVM
switch allows you to used multiple computers with the same keyboard, video
display, and mouse. Now, most of us don't need to use two computers at once. In
fact, using one computer at a time can sometimes be a challenge. However, there
are situations where using a single keyboard, mouse, and display with multiple
machines can be very practical.
For example, software programmers may use a KVM switch to alternate between two
or more computers with different operating systems. This allows them to test
their software on multiple platforms when developing a crossplatform
application. Network administrators often use KVM switches to monitor and
control multiple servers at a time. These KVM switches may support eight or more
computers at once. By simply pressing a button on the KVM switch, the
administrator can view the display of any machine connected to the switch and
control it with a single keyboard and mouse.
Of course, KVM switches can also be used by the everyday home user. Some people
may find it useful to have two computers at their desk, such as a home and work
computer, or a Mac and a PC. In these situations, a KVM switch can accommodate
both machines, allowing them to share the same monitor, keyboard, and mouse.
Because only one of each is needed, the result is far less clutter on the desk.
This leaves room for stacks of papers, mail, and other objects to clutter up the
rest of the desk.
Since most keyboards and mice use a USB connection, most KVM switches include
USB ports. Older models may include PS/2 or serial ports. The connection for the
monitor may be a VGA or DVI port, or both. If you plan on using a KVM switch for
your computer setup, make sure the ports match the display and input devices you
are going to use with it.
A file is a collection of similar records.
A database is a collection of interrelated files (meaning that records in
one file are physically related to records in another file).
Database
architecture refers to the database technology including the database engine,
database utilities, CASE
tools, and database development tools.
A database management system (DBMS) is specialized software that is used to create, access, control, and manage the database. The core of the DBMS is a database engine.
– A data definition language (DDL) is that part of the engine used to
physically define tables, fields, and structural relationships.
– A data manipulation language (DML) is that part of the engine used to
create, read, update, and delete records in the database, and navigate between
different files (tables) in the database.
Relational databases implement stored data in a series of two-dimensional tables that are “related” to one another via foreign keys.
– The physical data model is called a schema.
– The DDL and DML for a relational database is called SQL (Structured Query
Language).
– Triggers are programs embedded within a table that are automatically
invoked by updates to another table.
– Stored procedures are programs embedded within a table that can be called from
an application program.
Data are raw facts about the organization and its business transactions. Most data items have little meaning and use by themselves.
Information is data that has been refined and organized by processing and purposeful intelligence. The latter, purposeful intelligence, is crucial to the definition—People provide the purpose and the intelligence that produces true information.
Transaction processing systems
are information system
applications that capture and process data about business transactions.
– Includes data maintenance, which provides for custodial updates to stored
data.
– Business process redesign (BPR) is the study, analysis, and redesign of fundamental business (transaction) processes to reduce costs and/or improve value added to the business.
A management information system (MIS) is an information system application that provides for management-oriented reporting. These reports are usually generated on a predetermined schedule and appear in a prearranged format.
A decision support system (DSS) is an information system application that provides its users with decisionoriented information whenever a decision-making situation arises. When applied to executive managers, these systems are sometimes called executive information systems (EIS).
– A data warehouse is a read-only, informational database that is populated with detailed, summary, and exception data and information generated by other transaction and management information systems. The data warehouse can then be accessed by endusers and managers with DSS tools that generate a virtually limitless variety of information in support of unstructured decisions.
An expert system is a programmed decision-making information system that captures and reproduces the knowledge and expertise of an expert problem solver or decision maker and then simulates the “thinking” or “actions” of that expert.
– Expert systems are implemented with artificial intelligence technology that captures, stores, and provides access to the reasoning of the experts.
Office automation (OA) systems support the wide range of business office activities that provide for improved work flow and communications between workers, regardless of whether or not those workers are located in the same office.
– Personal information systems are those designed to meet the needs of a single user. They are designed to boost an individual’s productivity.
– Work group information systems are those designed to meet the needs of a work group. They are designed to boost the group’s productivity.
Information systems architecture provides a unifying framework into which various people with different perspectives can organize and view the fundamental building blocks of information systems.
• Rapid application development (RAD) techniques emphasize extensive user involvement in the rapid and evolutionary construction of working prototypes of a system to accelerate the system development process. RAD is based on building prototypes that evolve into finished systems (often using time boxing)
– A prototype is a smaller-scale, representative or working model of the users’ requirements or a proposed design for an information system.
– A time box is a nonextendable period of time, usually 60-120 days, by which a candidate system must be placed into operation.
Commercial off- the- shelf (COTS) software is a software package or solution that is purchased to support one or more business functions and information systems.
Data capture is the identification and acquisition of new data (at its source).
Data entry is the process of translating the source data or document (above) into a computer readable format.
Data processing is all processing that occurs on the data after it is input from a machine readable form.
An information system (IS) is an arrangement of people, data, processes, communications, and information technology that interact to support and improve day-to-day operations in a business, as well as support the problem-solving and decision-making needs of management and users.
Information technology is a contemporary term that describes the combination of computer technology (hardware and software) with telecommunications technology (data, image, and voice networks).
A model is a representation of reality. Just as a picture is worth a thousand words, most models are pictorial representations of reality.
Logical models show what a system is or does. They are implementation independent; that is, they depict the system independent of any technical implementation.
Physical models show not only what a system is or does, but also how the system is (to be) physically and technically implemented. They are implementation dependent because they reflect technology choices.
Process modeling is a technique for organizing and documenting the structure and flow of data through a system’s processes, and/or the logic, policies, and procedures to be implemented by a system’s processes.
A data flow diagram (DFD) is a tool (and type of process model) that depicts the flow of data through a system and the work or processing performed by that system.
A project is a [temporary] sequence of unique, complex, and connected activities having one goal or purpose and that must be completed by specific time, within budget, and according to specification.
Project management is the process of scoping, planning, staffing, organizing, directing, and controlling the development of an acceptable system at a minimum cost within a specified time frame.
A PERT chart is a graphical network model that depicts a project’s tasks and the relationships between those tasks.
A Gantt chart is a simple horizontal bar chart that depicts project tasks against a calendar. Each bar represents a named project task. The tasks are listed vertically in the left-hand column. The horizontal axis is a calendar timeline.
A work breakdown structure (WBS) is a hierarchical decomposition of the project into phases, activities, and tasks.
Milestones are events that signify the accomplishment or completion of major deliverables during a project.
Systems analysis is a problem-solving technique that decomposes a system into its component pieces for the purpose of studying how well those component parts work and interact to accomplish their purpose.
Systems design (also called systems synthesis) is a complementary problem-solving technique (to systems analysis) that reassembles a system’s component pieces back into a complete system-- hopefully, an improved system. This may involves adding, deleting, and changing pieces relative to the original system.
Rapid application development (RAD) is the merger of various structured techniques (especially the data- driven information engineering) with prototyping techniques and joint application development techniques to accelerate systems development. RAD calls for the interactive use of structured techniques and prototyping to define the users’ requirements and design the final system.
Joint Application Development (JAD) is a technique that complements other systems analysis and design techniques by emphasizing participative development among system owners, users, designers, and builders.
