redundancy Redundancy is a system design in which a component is duplicated so if it fails there will be a backup. Redundancy has a negative connotation when the duplication is unnecessary or is simply the result of poor planning.

tier In general, a tier (pronounced TEE-er ; from the medieval French tire meaning rank, as in a line of soldiers) is a row or layer in a series of similarly arranged objects. In computer programming, the parts of a program can be distributed among several tiers, each located in a different computer in a network. Such a program is said to be tiered , multitier , or multitiered . The 3-tier application model is probably the most common way of organizing a program in a network. N-tier applications (programs) are those that are tiered but the number of tiers isn't specified or may vary.

What is the meaning of the CRC counter on a cisco device? Short for cyclic redundancy check, a common technique for detecting data transmission errors. Transmitted messages are divided into predetermined lengths that are divided by a fixed divisor. According to the calculation, the remainder number is appended onto and sent with the message.

What is a Network? Although a network server is no more susceptible to failure than any other computer, when the files server goes down the entire network may come to a halt. Good network design practices say that critical network services (provided by servers) should be redundant on the network whenever possible.

What's the differences between âserverâ, âworkstationâ and âdesktopâ? From time to time, this term is used for any desktop computer. From that Linux book point of view, workstation is identical to desktop: it's just more powerful (and expensive). (From here) Server Computer providing services to other computers, for example websites or email service. When talking in context of this question, server can be any hardware from a laptop/desktop to dedicated server hardware. When running Linux, servers often do not run graphical console, as it is unnecessary for normal tasks, and consumes system resources (memory and CPU time).

repository In information technology, a repository (pronounced ree-PAHZ-ih-tor-i) is a central place in which an aggregation of data is kept and maintained in an organized way, usually in computer storage. The term is from the Latin repositorium, a vessel or chamber in which things can be placed, and it can mean a place where things are collected.

What is RAID 5 â RAID parity explained RAID is an acronym meaning “Redundant Array of Independent Disks”. As the name implies, RAID creates an array of multiple hard disks in order to provide redundancy. An array simply means a collection of drives that are presented to the operating system as a single logical device.

Computer cluster The components of a cluster are usually connected to each other through fast local area networks (LAN), with each node (computer used as a server) running its own instance of an operating system.hen a node in a cluster fails, strategies such as  fencing  may be employed to keep the rest of the system operational. Fencing is the process of isolating a node or protecting shared resources when a node appears to be malfunctioning.

Directory (computing) Directory (computing) In computing, a directory is a file system cataloging structure which contains references to other computer files, and possibly other directories. On many computers, directories are known as folders, or drawers to provide some relevancy to a workbench or the traditional office file cabinet. Files are organized by storing related files in the same directory. In a hierarchical filesystem, a directory contained inside another directory is called a subdirectory. The terms parent and child are often used to describe the relationship between a subdirectory and the directory in which it is cataloged, the latter being the parent. The top-most directory in such a filesystem, which does not have a parent of its own, is called the root directory.

Redundancy Redundancy. When the economy is in difficulties, redundancies are in the news every day. But even when times are better, redundancies still happen as firms reorganise or get taken over. Being made redundant is not the same as getting the sack: 1  Dismissal is what happens when your employer decides to get rid of you.2  Redundancy is when jobs disappear.edundancy is different. Strictly speaking, redundancy is a fair reason for dismissal, but since the legal requirements are different to other forms of dismissal, it is helpful to distinguish between the two. Redundancy happens when an employer reduces their workforce.

URGENT: For 10 points..Explain what it means to say that the genetic code is redundant and unambiguous? The genetic code is the code that translates a sequence of three nucleotides (called a codon) into an aminoacid. The genetic code has those two properties: Unambiguous: Each codon is translated into one single aminoacid. Always.This means that UUA is the code leucine no matter what.Redundant: In some cases, there are more than one codons for a single aminoacid.For instance UUA means leucine, but so does UUG.est Answer: In a molecule of DNA, many sequences are repeated and therefore essential not used. These repeated sequences are known as redundant DNA. Ambiguous DNA is sections where the code is not precisely known but its known that it is one of two bases. These are represented by characters e.g.

Computer data storage Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media that are used to retain digital data. It is a core function and fundamental component of computers.–16 The central processing unit of a computer is what manipulates data by performing computations. In practice, almost all computers use a storage hierarchy,–473 which puts fast but expensive and small storage options close to the CPU and slower but larger and cheaper ...
