Category 5 Ethernet cable - commonly known as Cat 5, is an unshielded twisted pair type cable designed for high signal integrity. The actual standard defines specific electrical properties of the wire, but it is most commonly known as being rated for its Ethernet capability of 100 Mbit/s. Most commonly used in networking.

Ethernet Hub - is a device for connecting multiple twisted pair or fiber optic Ethernet devices together, making them act as a single segment. It works at the physical layer of the OSI model, repeating the signal that comes into one port out each of the other ports.

IP address - is a unique number, similar in concept to a telephone number, used by network devices (routers, computers, time-servers, FAX machines, some telephones) attached to a network to refer to each other when sending information through a LAN (Local Area Network) or a WAN (Wide Area Network) or the Internet for example. This allows devices passing the information onwards on behalf of the sender to know where to send it next, and for the device receiving the information to know that it is the intended destination.

Although this might not be right but im pretty sure that it is actually measured in Megabits not bytes. so in actuall fact the actual speed would be about 12.5 Megabytes/sec. i may be wrong but im almost certain that is what it is. Same with firewire, wireless and USB.

Just thought i shoult mention these while im here

USB - Universal Serial Bus - Is the most commonly used connection with printers microdrives and cameras. Its speeds are for USB 1.1 is about 40megabits/sec and for USB 2.0 it is 480megabits/sec.

FireWire - Fire Wire is a less commonly used computer connection cable and is mainly used on external harddrives that are higher then 200gig. Fire wire can transfer ap to 200Mb/sec 400Mb/sec and 800Mb/sec.

Ethernet - is what is used to connect to lan and comes n a variety od different cables. it can transfer upto 10Mb/sec 100Mb/sec and 1000Mb/sec.

Wireless - Wireless is a connection that uses radio waves to transfer data and is commonly in laptops due to its portability. It has 3 different modes B G and N. B transfers at 11Mb/sec G tranfers at 54Mb/sec and N transfers at 108Mb/sec.

Correct me if im wrong. and i will creat an acount after this.

Pixel - a 1x1 square of colour used in visual operating systems. There are various levels of colour, such as 2-bit colour (black and white) and 32-bit colour. Odd are you have 16 or 32 bits of colour.

FLOPS - Floating Point Operations Per Second - A flops is the number of calculations an object can preform every second. A desktop computer can reach about 3 Gflops. Humans operate at an average of .0000001 flops (being generious). The Blue-Gene/P, to go online in 2006, will have and estimated speed of over 1 petaflops, or 1,000,000,000,000,000,000,000 times faster than a human doing long division.

LCD - liquid crystal display - is a thin, flat display device made up of any number of color or monochrome pixels arrayed in front of a light source or reflector. It is prized by engineers because it uses very small amounts of electric power, and is therefore suitable for use in battery-powered electronic devices.



BitTorrent - is the protocol and the name of the peer-to-peer (P2P) file distribution tool written by programmer Bram Cohen and written in Python and is released under the BitTorrent Open Source License (a modified version of the Jabber Open Source License), as of version 4.0. The name "BitTorrent" refers to the distribution protocol, the original client application, and the .torrent file type.

Third time I've had to edit your post here. Check the first page for the way your supposed to post definitions. -DK

SQL - Structured Query Language - SQL languages are databases used in storing information. SQL systems use tables, sorted by rows and columns. If you were to visually find a piece of data, it would almost be like battleship. SQL databases are popular because they are extremly fast, very efficent, and can store massive amounts of information. Currently MySQL is the most popular language, as it works well with PHP. SQLite, another SQL language, is becoming increasingly popular.

PHP - PHP: Hypertext Preprocessor - Currently one of the leading server-side languages on the internet. PHP is embedded within HTML pages, and as a command-line language. This forum is an example of a PHP generated system.

Frame rate - is the measurement of how quickly an imaging device can produce unique consecutive images called frames. The term applies equally well to computer graphics, video cameras, film cameras, and motion capture systems. Frame rate is most often expressed in frames per second (often abbreviated "fps", but not to be confused with FPS or first-person shooter) or, equivalently, Hertz (Hz).

Touch Pad - is an input device commonly used in laptop computers. They are used to move the cursor, using motions of the user's finger. They substitute for a computer mouse.

ACPI-Advanced Configuration and Power Interface - specification is an open industry standard first released in December 1996 developed by HP, Intel, Microsoft, Phoenix and Toshiba that defines common interfaces for hardware recognition, motherboard and device configuration and power management. According to its specification, "ACPI is the key element in Operating System-directed configuration and Power Management (OSPM)".

DDR (refering to RAM)-Double data rate- transfers data on both the rising and falling edges of the clock signal, effectively nearly doubling the data transmission rate without having to deal with the additional problems of timing skew that increasing the number of data lines would introduce. This is also known as double pumped, dual-pumped, and double transition.

IDE - IDE stands for Integrated/Intelligent Drive Electronics. It is an ATA specification (the terms are often used interchangably), also know as PATA. This is the most common disk interface for hard drives, CD-ROM drives, etc. It is easy to use, but also the most limited. IDE is integrated into your motherboard. It only allows for 4 devices.
also in software
IDE(Integrated Development Environment) combines the editor, compiler and other useful tools in the same software package. Its advantage is that when a program with syntax errors is compiled, the programmer sees the error messages and the original program at the same time -- this makes debugging much easier. Also, some IDEs contain debuggers. Visual J++, VisualAge for C++ or Java, Java WorkShop, and Visual Café are IDEs.


SCSI - This acronym is pronounced "scuzzy" and stands for Small Computer Systems Interface. There are two types of interfaces for hard drives, CD-ROM drives, etc. One is SCSI, the other is IDE. IDE is much more common and less expensive(see above). SCSI is more expensive and also more flexible and generally faster. With a single SCSI card you can have 15 or more devices. There is also SATA below. SCSI can transfer data at rates of 4 MB/sec.; in addition, there are several varieties of SCSI that support higher speeds: Fast SCSI (10 MB/sec.), Ultra SCSI and Fast Wide SCSI (20 MB/sec.), as well as Ultra Wide SCSI (40 MB/sec.).


SATA - Serial ATA, an serial link - a single cable with a minimum of four wires creates a point-to-point connection between devices. Transfer rates for Serial ATA begin at 150 MBps and SATA II 300MBps. One of the main design advantages of Serial ATA is that the thinner serial cables facilitate more efficient airflow inside a form factor and also allow for smaller chassis designs.

Blu-ray - Blu-ray Disc is a next-generation optical disc format meant for high definition video (HD) and high density data storage, and is one of two competing standards for HD optical media. Its competitor is HD-DVD. Blu-ray gets its name from the shorter wavelength (405 nm) blue laser that, in addition to other techniques, allows it to store substantially more data on the same sized disc than DVD, which uses a longer wavelength (650 nm) red laser.

HD-DVD - High-Density Digital Versatile Disc - DVD - HD-DVD is a digital optical media format which is being developed as one standard for high-definition DVD. HD-DVD is similar to the competing Blu-ray Disc, which also uses the same CD sized (120 mm diameter) optical data storage media and 405 nm wavelength blue laser. HD-DVD is promoted by Toshiba, NEC, and Sanyo, and backed by four major film studios. The Blu-ray Disc is proposed by Sony.

DVD - Digital Versatile Disc - DVD is an optical disc storage media format that can be used for storing data, including movies with high video and sound quality. DVDs resemble compact discs: their physical dimensions are the same—12cm or the mini 8cm—but they are encoded in a different format and at a much higher density. Unlike CDs, all DVDs must contain a file system. This file system is called UDF, and is an extension of the ISO 9660 Standard used for Data-CDs.

Doesn't anyone else have any terms? I post what I find while looking around. Also sorry abotu not editing, the edit button doesn't like me to much.

OEM - Original equipment manufacturer. When seen in a computer ad (eg, "Sound Blaster OEM"), this generally means a lower-cost product that does not come in a retail box, usually lacking in manuals, bundled software and other accessories.

Graphics Tablet - Tablet for short, is a computer peripheral device that allows one to hand-draw images directly into a computer, generally through an imaging program. Graphics tablets consist of a flat surface upon which the user may "draw" an image using an attached stylus, a pen-like drawing apparatus. The image generally does not appear on the tablet itself but, rather, is displayed on the computer monitor.

I think these might help people out a little.

Digital - Describes a method of storing, processing and transmitting information through the use of distinct electronic or optical pulses that represent the binary digits 0 and 1. Sometimes used to refer to a device that uses an lcd display and modern microchips such as Digital Watch, Digital Clock, or a Digital Display.

Analog - A form of transmission that is a continuous wave electrical signal that varies in frequency and/or amplitude in response to the variations of a physical phenomena such as human speech or music. In telephony, your voice is captured by a diaphragm within the telephone which causes a magnet to vibrate creating a continuously fluctuating electrical signal that is passed through a wire circuit and received on the other end. Sometimes used to refer to a device that uses knobs or a control that has to be turned and/or a device that displays information through mundane means, such as a Pocketwatch, or a Stereo that has a non-electronic station display.

Try to keep all your terms in the same post until someone else has posted, so as not to double/triple post. -DK

UPS - uninterruptible power supply: is a device or system that maintains a continuous supply of electric power to certain essential equipment that must not be shut down unexpectedly. The equipment is inserted between a primary power source, such as a commercial utility, and the primary power input of equipment to be protected, for the purpose of eliminating the effects of a temporary power outage and transient anomalies. They are generally associated with telecommunications equipment, computer systems, and other facilities such as airport landing systems and air traffic control systems where even brief commercial power interruptions could cause injuries or fatalities, serious business disruption or data loss.

NTFS - New Technology File System: is the standard file system of Windows NT and its descendants Windows 2000, Windows XP and Windows Server 2003. NTFS replaced Microsoft's previous FAT file system, used in MS-DOS and early versions of Windows. NTFS has several improvements over FAT such as improved support for metadata and the use of advanced data structures to improve performance, reliability and disk space utilization plus additional extensions such as security access control lists and file system journaling. Its main drawback is its very limited support by non-Microsoft OSes, since the exact specification is a trade secret of Microsoft.

Podcasting- The method of distributing multimedia files, such as audio programs or music videos, over the Internet for playback on mobile devices and personal computers. Podcasts are distributed using either the RSS or Atom syndication formats. May also be known as Podstreaming.

Zend- The Zend Engine is an open source scripting engine (a Virtual Machine), commonly known for the important role it plays in the web automation language PHP. It was originally developed by Andi Gutmans and Zeev Suraski while they were students at the Technion - Israel Institute of Technology. They later founded a company called Zend Technologies in Ramat Gan, Israel. The name Zend is a portmanteau of their forenames, Zeev and Andi.

Malware- Software designed to infiltrate or damage a computer system, without the owner's consent. The term is a portmanteau of "mal-" (or perhaps "malicious") and "software", and describes the intent of the creator, rather than any particular features. Malware is commonly taken to include computer viruses, worms, Trojan horses, spyware and adware.

Runtime- The operation of a computer program, the duration of its execution, from beginning to termination (compare compile time). The term is also used as a short form when referring to a runtime library (without a space), a program or library of basic code that is used by a particular computer language to manage a program written in that language while it is running.

Hardcoded- The software development practice of embedding output data directly into the source code of a program or other executable object, or fixed formatting of the data, instead of obtaining that data from external sources or generating data or formatting in the program itself with the given input. Hard coding requires the program's source code to be changed any time the input data or desired format changes, when it might be more convenient to the end user to change the detail by some means outside the program.

Whitebox- A homemade or 'small computer shop' made computer.

Code Monkey- A person only capable of grinding out code, but unable to perform the higher-primate tasks of software architecture, analysis, and design. Mildly insulting. Often applied to the most junior people on a programming team.

Real Programmer- A sarcastic, sometimes pejorative term used by computer programmers to describe an archetypical, "hardcore" programmer. A real programmer eschews modern or graphical tools, such as integrated development environments, or languages other than assembly language or machine code, in favour of solutions which are more direct, or "closer to the hardware".

Hacking-is a term used both by those who write code and those who exploit it. Even though these two groups of hackers have different end goals, both groups use similar problem-solving techniques. And because an understanding of programming helps theose who exploit, and an understanding of exploitation helps those who program, many hackers do both. There are interesting hacks found in both the techniques used to write elegant code and the techniques used to exploit programs. Hacking is really just the act of finding a clever and counterintuitive solution to a problem.

TCP/IP Hijacking-TCP/IP hijacking is a clever technique that uses spoofed packets to take over a connection between a victim and a host machine
RST Hijacking-A very simple form of TCP/IP hijacking involves injecting an authentic-looking reset(RST) packet.
DoS Attack-Denial of service attack is another form of RST hijacking, instead of trying to steal information, a DoS attack simply prevents access to a service or resource.

NOP-No operation
Format Strings-Format-string explotis are a relatively new class of exploit. The ultimate goal of a format-string exploit is to overwrite data in order to control the execution flow of a privileged program.
Direct Parameter Access-Direct parameter access is a way to simplify format-string exploits.
Shell-Spawning Code-Shell-spawning code is simple code that executes a shell.

Assembly language - A low-level programming language specific to an individual processor type. (IE. x86, x64, SPARC) The main advantage of the language lies in it's quick execution speed and high level of optimization due to the level of control over the processor.

PEBCAC - Problem Exists Between Chair and Computer - 95% cause of every error, glitch, hiccup, and lockup a computer can experience, ever.

You didn't use proper form. xD But that's the best acronym here. -DK
