Jumpers are small devices that are used to control the operation of hardware devices directly, without the use of software. They have been around since the very first PCs, and are still used on many types of modern hardware today. A jumper consists of two primary components: Jumper: The jumper itself is a small piece of plastic and metal that is placed across two jumper pins to make a connection, or removed to break a connection. They come in a few standard sizes (and some non-standard ones I'm sure); only one or two sizes are commonly seen on PCs. Jumpers are sometimes also called shunts. Jumper Pins : A set of pins, across two of which a jumper is placed to make a specific connection. Note: Some people actually call the jumper pins the "jumper"; others call the pins plus the jumper a " jumper ". The terms are used rather loosely, but it's nothing to worry about. A jumper is a mechanical switch that is easily modified by hand. Essentially, it's a circu

Installing Windows 2000 Professional In this section you will learn how to install Windows 2000 Professional. The basic steps, which are required for the installation and configurations. There are different methods of installing the Windows 2000 Professional .There are two basic types of the installation. Fresh Installation2. Dual Boot Installation In the fresh installation method, Windows 2000 is installed as the only operating system on a formatted or empty hard disk. In the dual boot installation method Windows 2000 Professional is installed alongside another operating system on the same hard disk such as Windows NT, Windows XP, Windows 98 or Red hat Linux. All the operating systems are needed to be installed on the separate portions of the hard disk. Just start from the Windows 2000 Professional installation CD. Make sure that your computer is set to boot from the CD first. To get the grip on Windows 2000 Professional installation and for easy to understand, I have discussed all th

To illustrate how the computer works, let's take a very simple example. Let's suppose you are working in your word processor and you type the letter "M". Here's what happens, in general terms, when you press the " M " button: The keyboard sends an electrical signal, called a scan code, to the computer saying that a button was pressed. The keyboard controller interprets the scan code and determines that the letter pressed was an " M ". It stores this " M " in a special memory location until the processor is ready to deal with it. The controller sends a signal to the processor, called an interrupt. An interrupt tells the processor that some part of the computer has information for it to process and wants its attention. In this case, the keyboard controller wants the processor to look at the key you just pressed. The processor is almost always doing many things, sharing its time among many tasks. As a result, most every event must wait i

Here you will find subnet network overview, ip addressing, address translation, network overview, subnet masking and subnetting overview . A subnet or a subnetwork is a separate part of an organization’s network. In a subnet all the machines are typically in one room, building or at one geographical location. By dividing an organization’s network into the subnets allows it to connect to the internet by using the same shared network address. Without subnet’s an organization may get different connections to access the internet. Subnetting is the modification of a single IP network to create two or more logically different networks. A subnet allows the flow of network traffic between hosts to be segregated based on the configuration of a network. Subnetting can improve the network security and performance by arranging the hosts into the different logical groups . Subnetting is required when one network address needs to be distributed across multiple network segments. Subnetting is require
