I hate it when I walk into an office and see people crouched over tiny computer screens on hard seats with a mouse and keyboard, looking tired and in pain. There is nothing worse than going to work and sitting in the same position (especially if its a wrong position) for hours at a time. Its easy to do permanent damage to your body, and that is something that you really want to avoid! Everything that you purchase should encourage the right posture (in other words have good ergonomics). This includes the chair, desk, wrist pad, keyboard, screen and even the computer. One of the easiest ways to get a poor posture is having a chair that is not comfortable to sit on. Having a small screen also...

You've been into the LAN settings of your browser many times and you probably wondered what the automatic configuration script is. That script is basically a file stored as a PAC file. A PAC file instructs your browser how to connect to the different sites in the internet. This PAC file is basically a text file which has some JavaScript codes in it. It is commonly called proxy.pac, but it can be named differently. For most of the home users, this script is not needed since they are connected to the internet directly. But if you're using a number of proxies, and each proxy is dedicated to some sites, you will need to use this file. A very basic PAC file contains a single function defining the...

When shopping for a computer business system, you need to first know exactly for what purpose the machine is to be used. For simple word processing and spreadsheets, you don't need a powerful system that is built for high speed graphic design. You can get by with a lower end system if the computer is going to be used primarily for data entry and secretarial work. Something that has to be kept in mind is that most applications like to have plenty of RAM, even some of the more basic word processing and spreadsheet applications will run a lot quicker if you have at a minimum of 1 to 2 GB of memory. Many businesses look to save on computer costs by cutting memory, not realizing that not having enough...

Behind all the names on the urls of Internet websites are a series of numbers called IP (Internet Protocol) addresses. IP stands for Internet Protocol, and constitute the primary network layer for use on the Web. The 127.0.0.1 IP This particular IP address, also called a local host, is the basis for which loopback network connections are processed. Loopback means going back, and that is what 127.0.0.1 does, because it is the address of your machine. Using telnet, ftp, or try in any way to get to 127.0.0.1, you will be transported back to the host machine, yours. However, it is only the initial three numbers (127) that are needed; use any number combination with 127 and the result will be the same. A...

If you learned how to type on a typewriter or were taught to type by someone who did, you are probably making a few typographical faux pas when typing on your computer. Single-Spacing The most common error is double-spacing at the end of a sentence. Only one is necessary, let me explain why. The reason why the double-space rule was applied to typewriters is because all typewriters use monotype fonts. Each letter in a monotype font is designed to have the same character width, in other words, an "m" will use the same amount of horizontal space as an "i" or an "l". There are several monotype fonts designed for the compute, Courier is probably the most well known. Most fonts used on computers are...

We have just learned that network processes communicate with each other by sending messages into sockets. But how are these messages structured? What are the meanings of the various fields in the messages? When do the processes send the messages? These questions bring us into the realm of application-layer protocols. An application-layer protocol defines how an application's processes, running on different end systems, pass messages to each other. In particular, an application-layer protocol defines:o The types of messages exchanged, for example, request messages and response messageso The syntax of the various message types, such as the fields in the message and how the fields are delineatedo The...
