How Domain Name Servers Work

How Domain Name Servers Work
by Marshall Brain
 

If you spend any time on the Internet sending e-mail or browsing the Web, then you use domain name servers without even realizing it. Domain name servers, or DNS, are an incredibly important but completely hidden part of the Internet, and they are fascinating! The DNS system forms one of the largest and most active distributed databases on the planet. Without DNS, the Internet would shut down very quickly.
 

In this post, we will take a look at the DNS system so you can understand how it works and appreciate its amazing capabilities.

How Routing Algorithms Work [ Very Useful info ]

How Routing Algorithms Work
by Roozbeh Razavi
 

If you have read the article How Routers Work, then you know that a router is used to manage network traffic and find the best route for sending packets. But have you ever thought about how routers do this? Routers need to have some information about network status in order to make decisions regarding how and where to send packets. But how do they gather this information?
 

In this edition of How Stuff Works, we'll find out precisely what information is used by routers in determining where to send a packet.

How RAM Work [ Also Learn How to Install it. ]

How RAM Work
by Jeff Tyson

Random access memory (RAM) is the best known form of computer memory. RAM is considered "random access"because you can access any memory cell directly if you know the row and column that intersect at that cell.

The opposite of RAM is serial access memory (S s a series of memory cells that can only be AM). SAM stores data accessed sequentially (like a cassette tape). If the data is not in the current location, each memory cell is checked until needed data is found. SAM works very w fo re the data is normally stored in the order in which will be used (a good example is the texture buffer memory on a video card). RAM data, on the other hand, can be accessed in any order.

How OSI Layers Works [ In Less than 2 Minute ]

How OSI Works also Known as & 7 Layers of Operation System
by Jeff Tyson

Virtually all networks in use today are based in some fashion on the Open Systems Interconnection (OSI) standard. OSI was developed in 1984 by the International Organization for Standardization (ISO), a global federation of national standards organizations representing approximately 130 countries.

The core of this standard is the OSI Reference Model, a set of seven layers that define the different stages that data must go through to travel from one device to another over a network. In this article, you'll find out all about the OSI standard.

How Microprocessors Work [ History ]

How Microprocessors Work
by Marshall Brain
 

The computer you are using to read this page uses a microprocessor to do its work. The microprocessor is the heart of any normal computer, whether it is a desktop machine, a server or a laptop. The microprocessor you are using might be a Pentium, a K6, a PowerPC, a Sparc or any of the many other brands and types of microprocessors, but they all do approximately the same thing in approximately the same way.
 

If you have ever wondered what the microprocessor in your computer is doing, or if you have ever wondered about the differences between types of microprocessors, then read on. In this article, you will learn how fairly simple digital logic techniques allow a computer to do its job, whether its playing a game or spell checking a document!
