R:

Random Access Memory (RAM) - A computer's volatile or temporary memory, which exists I n chips on the motherboard near the CPU. RAM stores data and programs while they are being used and require a power source to maintain integrity.

Range - In a spreadsheet, a rectangular group of contiguous cells.

Read-Only Memory (ROM) - A permanent, or non-volatile , memory chip is used to store instructions and data, including the computer's startup instructions. ROM's contents cannot be altered.

Read/Write Head - The magnetic device within the disk drive that floats above the disk surface and read, records and erases data on the disk . A read/write head contains an electromagnet that alters the polarity of magnetic particles on the storage medium; most disk drives have one read/write head for each side of each disk in the drive.

Real-Time Processing - The ability to process information as it is received, provides immediate response to input.

Record - A database row composed of related fields; a collection of records makes up the database.

Reduced Instructions Set Computing (RISC) Processor - A microprocessor design that simplifies the instruction set, using fewer instructions of constant size, each of which can be executed in one machine cycle.

Refresh Rate - The number of times per second that each pixel on the screen is scanned; measured in hertz(Hz).

Register - High-speed memory locations built directly into the ALU and used to hold instructions and data currently being processed.

Relational Database - A database structure capable of linking tables; a collection of files that share at least one common field.

Relative Cell Reference - A spreadsheet cell reference that changes with respect to its relative position on the spreadsheet when copied to a new location.

Remote Administration - The process of administering a network from a remote location, through a modem connection. The connection is established between the administrator's remote computer and a computer on the network-usually either the administrator's own node or a network server.

Removable Hard Drive - A magnetic storage device that combines the speed and capacity of a hard disk with the portability of a diskette. A removable box encloses the disk , drive and read/write heads in a sealed container that can be moved from computer to computer.

Render - To create an image of an objects as it actually appears.

Repetitive Stress Injury (RSI) - An injury to some part pf the body caused by continuous movement, computer-related injuries include wrist, neck, sand back strain.

Report - A database product designed by the user that displays data satisfying a specific set of search criteria s a matrix.

Resolution - Refers to the sharpness and clarity of an image. The term is most often used to describe monitors, printers, and bit-mapped graphic images. In the case of dot-matrix and laser printers, the resolution indicates the number of dots per inch. For example, a 300-dpi (dots per inch) printer is one that is capable of printing 300 distinct dots in a line 1 inch long. This means it can print 90,000 dots per square inch.

For graphics monitors, the screen resolution signifies the number of dots (pixels) on the entire screen. For example, a 640-by-480 pixel screen is capable of displaying 640 distinct dots on each of 480 lines, or about 300,000 pixels. This translates into different dpi measurements depending on the size of the screen. For example, a 15-inch VGA monitor (640x480) displays about 50 dots per inch.

Printers, monitors, scanners, and other I/O devices are often classified as high resolution, medium resolution, or low resolution. The actual resolution ranges for each of these grades is constantly shifting as the technology improves.

Resolution Dependent - Describes an image determined by the number of pixels on a screen, expressed as a matrix.

Resolution Independent - Describe an image whose appearance will not change, depending on the resolution at which it is displayed.

Right-Click - When using a two-button mouse to use the right mouse button to select an object or command on the screen.

Ring Topology - A network topology in which network nodes are connected in a circular configuration. Each nodes Examines the data sent through the ring and passes on data not addresses to it.

RISC Processor - See Reduced Instruction Set Computing Processing.

Robot - The software for indexing and updating Web sites. It operates by scanning documents on the Internet via a network of links. A robot is also known as a spider, crawler and indexer.

ROM - See Read-only memory.

Router - A computer device that stores the addressing and uses this information to transfer data along the most efficient path between nodes of LAN or WAN.

Routine - A name sometimes described to reusable blocks of code. See also procedure and subroutine.

Row - A horizontally arranged series of cells in a spreadsheet, named with a number.

RS-232 - The standard serial port configuration used for communications between the computer and peripherals.

Ruler - An on-screen tool in a word processor's document window. The ruler shows the position of lines, tabs tops, margins, and other parts of the document.

Running - See executing.

Runtime - Occurring while a program is executing. For example, a runtime error is an error that occurs during program execution and a runtime library is a library of routines that are bound to the program during execution. In contrast, compile-time refers to events that occur while a program is being compiled.

Takumi's Comment
My wireless rouetr is in the basement with limited coverage for the 2nd floor and the patio. So my aim was to expand my wireless network coverage. ASUS WL-330gE proved best value and has several functions one of which is to expand the wireless network (labeled as Repeater mode). Now I have an excellent coverage all over my property. The following are the steps I did to set it up: 1. Power on your WL-330gE through the attached USB power cord. 2. Connect the WL-330gE to your laptop through an Ethernet (RJ45) cable. 3. Disconnect your computer from internet/rouetr. (Wireless off or unplug Ethernet cable) 4. Open the Internet browser in your computer and type in 192.168.1.220 in the address box. Type admin for ID and admin for password. 5. Select Repeater tab 6. From the available wireless devices select yours enter your password and connect. 7. Click on the advanced setting at the lower left corner and select IP config then select Yes for get IP Automatically. 8. Click apply then logout. 9. Disconnect your ASUS from the computer. Find a central location in your property and connect the device to the power outlet. You do not need to connect it to the net work or a computer
