RAM --- Real Name

 
RAM --- Random-Access Memory --- The part of the computer's memory that stores information temporarily while you're working on it. Typically, Windows 95 machines have 16 million bytes (16M) of RAM or more. However,

Raster font --- A font in which characters are stored as pixels.

Reader --- A program used to read a file, on the 'net, usually used to refer to a program for posting usenet messages to & from.

Readme --- A file found in an Internet host's directory that describes the computer and its service. It is one of the files that newcomers to the host are advised to download and read because the information contained is useful. There are also readme files that come bundled with personal computer software that give the latest information about installation, known bugs and incompatibilities, and product documentation errata and addenda.

Read-only --- Characteristic of a file indicating that the file can be read from, but not written to, by an application. Note however, that a "read-only" file can be deleted in Explorer, although you will get a warning (beyond the normal "are you sure" you normally get when you try to delete a file) if the file is read-only.

Real mode --- As opposed to protected mode, real mode is a mode in which Intel x86 processors can run. Memory addressing in real mode is nonlinear, requiring a program to stipulate a segment and memory offset address in order to access a location in memory. Originally appeared on the Intel 8086 CPU and has been the bane of PC programmers ever since. Although subsequent CPU chips supported protected-mode linear addressing, backward compatibility with the thousands of real-mode applications slows the evolution of operating systems. Note that all Intel CPUs boot in real mode and require specific software support to switch into protected mode.

Real Name --- A way for Internet users to assign "real names" to Web sites to more easily remember the URL or Web address. With Real Name for example a user can assign the name WORDS to the URL http://www.high-density.com, this allows a user to go to the Web site by just typing in WORDS.

The Real Name setup process involves going to the Real Name Web site and downloading the Real Name extension and installing it on your computer.

Real Soon Now --- Registering a program

 
Real Soon Now --- A vague term used to describe when something will actually happen.

Real time chat --- A program allowing live conversation between individuals by typing on a computer terminal. The most common tools are Talk and IRC (International Relay Chat).

RealAudio --- Progressive Networks' RealAudio client-server software system enables Internet and online users equipped with conventional multimedia personal computers and voice-grade telephone lines to browse, select, and play back audio or audio-based multimedia content on demand, in real time. This is a real breakthrough compared to typical download times encountered with delivery of audio over conventional online methods, in which audio is downloaded at a rate that is five times longer than the actual program; the listener must wait 25 minutes before listening to just five minutes of audio.

Reciprocal link --- A hyperlink or link placed on one Web site to return the favor of another site putting a link on their page.

Recycle Bin --- An icon that appears on the Windows 95 desktop. To discard a file, you drag the file from Explorer, My Computer, or any other file handler to the Recycle Bin. This action hides the file--but doesn't actually erase it from the disk. You can "undelete" the file by dragging it from the recycle bin back to a folder. To actually delete the file, select the Recycle Bin menu selection to empty the recycle bin.

Restore button --- A button in the upper right corner of a Window that has two squares in it. When clicked, it returns the window to its previous size. When the window is at its previous size, the restore button switches to the maximize button, which returns the window to its maximum size

Referrer --- URL of an HTML page that refers to your Web site.

Registering a program --- The act of linking a document with the program that created it so that both can be opened with a single command. For example, double-clicking a DOC file opens Word for Windows and loads the selected document.

Registry --- Resource (card)

 
Registry --- A database of configuration information central to Window 95 operations. This file contains program settings, associations between file types and the applications that created them, as well as information about the types of OLE objects a program can create and hardware detail information.

Registry Editor --- The Registry Editor ships with Windows 95. Using this tool you can fine tune Windows 95 performance by adjusting or adding settings to key system information. Since Windows 95 has placed WIN.INI and SYSTEM.INI file settings in the registry, the ability to remotely edit these parameters is an extremely powerful tool. Warning: you can totally destroy a workstation using this tool!

Remote terminal --- It is possible to login to a remote computer by using an application program based on TELNET - a terminal emulation >protocol made for this purpose. The user can therefore enter commands on a keyboard attached to their local computer and access files etc. on a remote computer that may be located anywhere in the world.

Repeater --- A device that repeats or amplifies bits of data received at one port and sends each bit to another port. A repeater is a simple bus network device that connects two cabling segments and isolates electrical problems to either side. When used in a LAN, most repeaters take a role in reconstituting the digital signal that passing through them to extend distances a signal can travel, and reduce problems that occur over lengths of cable, such as attenuation.

Resize button --- A button located in the lower left corner of a non-maximized window. When the mouse pointer is over this button, it turns into a two-headed arrow. You can click and drag to resize the window horizontally and vertically.

Resource (card) --- When installing a card, certain "resources" are needed: these often include a DMA channel, I/O Base address, and IRQ. Although these are detected and set automatically with Plug and Play compliant cards, you will have to set them using jumpers or the setup program to store the resource values in non-volatile RAM when installing a "legacy" (pre-Plug and Play) card.

Restore files --- Return Code

 
Restore files --- Copies one or more files from your backup set to the hard disk or to another floppy.

Return Code --- The return status of the request which specifies whether the transfer was successful and
why.

Possible "Success" codes are:
200 = Success: OK
201 = Success: Created
202 = Success: Accepted
203 = Success: Partial Information
204 = Success: No Response
300 = Success: Redirected
301 = Success: Moved
302 = Success: Found
303 = Success: New Method
304 = Success: Not Modified
Possible "Failed" codes are:
400 = Failed: Bad Request
401 = Failed: Unauthorized
402 = Failed: Payment Required
403 = Failed: Forbidden
404 = Failed: Not Found
500 = Failed: Internal Error
501 = Failed: Not Implemented
502 = Failed: Overloaded Temporarily
503 = Failed: Gateway Timeout

RFC --- ROutable protocol

 
RFC --- Request For Comments --- The name of the result and the process for creating a standard on the Internet. New standards are proposed and published on line, as a "Request For Comments". The Internet Engineering Task Force is a consensus-building body that facilitates discussion, and eventually a new standard is established, but the reference number/name for the standard retains the acronym "RFC", e.g. the official standard for e-mail is RFC 822.

RGB --- Red, Green, Blue --- The three colors that create all other colors on a computer screen.

Rich text format (RTF) --- RTF (Rich Text Format) is compatible with several word processors and includes fonts, tabs, and character formatting.

Ring network --- One of a variety of network topologies. Ring networks connect computers by using an In and an Out port for data. Each computer sends information to the next computer down the wire. Data flows from one computer's Out port to the next computer's In port.

ROT-13 --- A simple encoding program for usenet, which is usually used to warn readers that if they decode the post, they're likely to find obscene material, usually a "dirty joke."


ROTFL --- Rolling On The Floor Laughing --- A shorthand appended to a comment written in an online forum or e-mail.

ROundtable --- Term used by GEnie for a SIG.

ROutable protocol --- A network protocol that can work with non proprietary routers. Traditional routers use the network packet header fields to identify network addresses (network numbers)/node addresses for ultimate source and destination nodes (or hosts) for packets of data. This scheme for routing packets across internetworks is used OSI, NetWare (IPX), TCP/IP, and AppleTalk network protocols.

ROuter --- RFC

ROuter --- RFC

 
ROuter --- In a network, a device that reads network layer packet headers and receives or forwards each packet accordingly. Routers connect LANs and WANs into internetworks, but must be able to process the network packets for specific types of network protocol. Many routers process various packet types and therefore are termed multiprotocol routers.

RTFM --- Either "Read the F****** Manual" or "Read the FAQ, Moron," depending on the usage.

ROM --- Read-Only Memory. A type of chip capable of permanently storing data without the aid of an electric current source to maintain it, as in RAM. The data in ROM chips is sometimes called firmware. Without special equipment, it is not possible to alter the contents of read-only memory chips, thus the name. ROMs are found in many types of computer add-in boards, as well as on motherboards. CPUs often have an internal section of ROM as well.

RTM --- Read The Manual --- A shorthand appended to a comment written in an online forum or e-mail.

RFC --- (Request For Comments) -- The name of the result and the process for creating a standard on the Internet. New standards are proposed and published on line, as a Request For Comments. The Internet Engineering Task Force is a consensus-building body that facilitates discussion, and eventually a new standard is established, but the reference number/name for the standard retains the acronym RFC, e.g. the official standard for e-mail is RFC 822.
