CAD (Computer-Aided Design) is a category of software program used by engineers and designers to create virtual models or drawings on-screen to communicate their ideas, often, used with construction software .

This type of software is used many professional disciplines today, including mechanical design, architecture, structural and civil engineering, electrical design, and many others. A mechanical engineer will create “solid models” of a suspension component or a piston inside an engine. An electrical engineer might use CAD to sketch out a circuit diagram, and a circuit board designer would use CAD to organize the layers of “traces” or lines that carry the signals in the circuit design. Even information technology professionals use CAD to “layout” all of the wiring and cable routing needed to connect all of the computers on a corporate network.

There are many advantages that CAD software has brought to the world of design and engineering, and the primary advantages are all based on faster flow of information and easier change in direction. Before CAD, an engineer would work with a drafter to draw, by hand, an idea on a two-dimensional piece of paper. The engineer and drafter would work back and forth until the “thing” documented in the drawing matched the mental imagery in the engineer’s imagination. Then this original hard-copy drawing would be duplicated and sent to someone who built or fabricated what was represented. The engineer would review the results, and then work with a drafter again change the drawing as necessary, if the physical result didn’t match the original concept or idea.

Now, a designer or engineer can use two-dimensional (lines) or three-dimensional (shapes) modeling software to “sketch” his or her own ideas on a computer screen, in a matter of minutes. In the example of a mechanical designer or engineer using the tool, a virtual object can be spun around to view it from many angles, and it can be assembled to other virtual objects, or analyzed for strength or weight, checked for fit and interferences. The idea can be presented to peers, supervisors, metal fabricators, assembly technicians, and even customers, to get feedback long before time and money are invested in formal documentation, prototyping or manufacturing, and so on. In this way, CAD software provides any number of opportunities for making a design development project significantly more efficient.

No matter what kind of software you use (including construction accounting software), networking matters.

The connecting of two or more computers in a home, school or business is called “networking”. We do this to easily share files, software programs, and printers on a ‘remote’ computer. The network is created using software installed on each computer system in the new network, and hardware that will vary depending on your own requirements and needs. There are special home network creation programs and kits with a CD you can easily buy online or in a store that will walk you through each step. Windows XP does include a ‘network setup wizard’ that will help an experienced computer user easily set up the network. There are various ways to connect the network: patch cabels, wireless WiFi, Power-line Networking, and Phone-line Networking.

Almost every household now owns a computer, but many people don’t have a clue as to what many computer terms mean or how to even get around on one. It is not as hard as it seems, and there are many inexpensive classes out there to teach you how to use your new personal computer or more commonly known as a pc. Most new computers come set up with programs already installed. A cd comes with your pc with easy to follow instructions. An (ISP) stands for internet service provider. This is the company that you choose and pay so you can connect to its computer and get on the Internet. The Internet is a group of computers all over the world that are connected to each other. Using your computer and a modem, you can connect to these other computers and tap their resources. You can view pictures, watch video clips, play action games, chat with other people, and shop without leaving your home.

A modem is hardware that enables a computer to send and receive data through an ordinary telephone line or television cable. The monitor is the screen on which the computer displays information. A browser is a program used to view pages on the Web. Internet Explorer and Netscape Navigator are currently the two most popular browsers. The toolbar is a strip of buttons typically displayed near the top of a program window, below the menu bar. The toolbar contains buttons called icons that you can click to enter common commands. Essentially these toolbar icons are shortcuts allowing you to bypass the menu system. An icon is a graphic image onscreen that looks like a little picture. An icon represents another object, such as a program, file or folder.

The taskbar is the button bar that runs across the bottom of the Windows desktop. On the left is the Start button and on the right is usually a digital clock and a few program icons. When you are using programs, each one shows a button on the taskbar. When you click one of these buttons, the corresponding window comes to the front of your screen and becomes the active window. You can close this window by clicking on the X at the upper right hand side of your screen. A search engine is a site, or part of a site, that allows you to search for words and phrases either locally or on the world wide web. For instance, www. Google.com. The arrows to the right of your screen allow you to move the page up and down which is referred to as scrolling.Your cursor is the small triangular shaped pointer that travels across your monitor scren as you move your mouse. Anything that you type appears at the place where the cursor is flashing on your screen.

The mouse is a hand-held device that you move across the desktop to move an arrow, called a mouse pointer, across the screen. Used instead of the keyboard to select and move items such as text or graphics, execute commands, and perform other tasks. Megabyte is a standard unit used to measure the storage capacity of a disk and the amount of computer memory. A virus is a program that attaches itself to other files, duplicates itself without the user’s knowledge, and may cause the computer to do strange and sometimes destructive things. The virus can attack the computer by erasing files from the hard disk or by formatting the disk, which can destroy all your data. Viruses are frequently transmitted through programs attached to e-mail messages. It is extremely important that you buy the latest anti-virus software and install it on your computer.
