Are you tired of those slow downloads you’re getting when you surf the internet? Bored of waiting just to make a few transactions in your e-billing account? Then forget your old modem and switch to ADSL. For those of you that are not familiar with this new technology, let me explain a little bit about what it is. Asymmetric Digital Subscriber Line (ADSL) is a transmission technology that enhances the use of existing telephone lines, providing high-bandwidth data and voice services. This is possible taking advantage of unused high frequencies of existing copper wiring in the PSTN (Plain Switched Telephone Network), allowing data to travel back and forth on the high frequencies while voice simultaneously travels back and forth on the lower frequencies without experiencing interruptions. It is asymmetrical because the download speeds (1.4 Mbps) are much faster than the upload speeds (256 kbps); this means that it’s faster to download a file than to upload a file to the same server.
Having said this I’ll focus on how to install an ADSL modem, a modem for those of you that don’t know is an acronym for Modulator Demodulator, a modem is a device that converts data from digital computer signals to analog signals that can be sent over a phone line, this is called modulation. The analog signals are then converted back into digital data by the receiving modem, this is called demodulation. In this occasion I have chosen the latest of Microsoft Operating Systems, which is Windows XP, hopefully by the time you read this, Microsoft has not come up with something newer, since they change Operating Systems like we change clothes.
First we need to make sure that the PC meets the minimum system requirements, for Windows XP they are: a 300Mhz processor or faster, a processor is an integrated circuit that executes the instructions of a program that drives the computer, 128MB of memory, 100MB of free disk space, a CD-ROM drive, a Network Interface Card, a NIC is a circuit board that allows the computer to connect to a network, and a Super VGA monitor (800x600) or higher resolution video adapter.
Well, with all this taken into consideration let’s get started, there are different kinds of modems that accomplish these task, but I will select one with an Ethernet port, Ethernet is one of the most widely-installed local area network (LAN) technologies, that provides transmission speeds of up to 10Mbps, which is more than enough for ADSL speeds.
Windows hardware’s has played a vital role in current technology of computer era. Computer application has significantly changed the workloads and manual records and information keeping has been significantly managed easily. This has been tremendously associated with the respective improvements with the software and hardware application development and Windows Xp and windows 7 have been most powerful operating system used by many computer applicants and users.
It is 8:45 and Paul has just gotten on the interstate to make his normal commute to Longview from Tyler. About halfway there, Paul notices a state trooper right behind him. He frantically checks his speed! Too late!!!!!! The state trooper turns on his lights. Not only was Paul speeding, but now he will be late to a very important meeting at work.
This essay is to inform you about certain aspects of driving. In this letter I am going to talk about the effect of response time, a safe following distance, how the stopping distance depends on speed, how to decide what to do at a yellow light and how you have to change your speed around a curve. In the next following paragraphs I will explain each of the topics that I have listed and I will give you a better knowledge of how to be a safer driver.
Before you start you will need to check if u need all of your pieces together and parts. Then you need to check if you have the right size case for your mother board. The find a bare floor to work on its the best place. Then download latest drivers for your pc so you cannot
Surfing is the sport of riding a surfboard toward the shore on the crest of a wave. It is an amazing sport to learn and it gives the rider a hell of an adrenaline rush!! There are three major phases of surfing – paddling, push up and the standing position. This report will give you a full understanding of the correct techniques to use while surfing and it also describes the basic structure and function of the muscular-skeletal and cardio-respiratory systems of the human body. It will also describe the many different energy systems and how they change when surfing.
A high speed Internet connection is required to stream video. The Netflix Help Center recommends an Internet connection speed of 5.0 Megabits per second (Mbps) for HD video ("Internet Connection Speed Recommendations") Today most American households have access to broadband speeds capable of high-definition video. According to Anne Neville of the National Telecommunications and Information Administration, 98% of Americans have access to broadband speeds of six megabits per second and 83% to speeds of twenty five Mbps or more (Neville). These speeds are more than adequate for HD quality video streaming. With the current broadband initiatives in place this should continue to improve in coming years, along with the possibility of even greater speeds. Beginning in November 2013, Cox Communications began offering increased Internet connectio...
Each computer on the network uses a modem to connect to the ISP (Internet service Provider eg Eircom) which operates the telephone lines. When you connect to the internet you become part of their network. Companies may be part of a Local Area Network all connected at points of presence in various cities. There is no overall connecting network but several high level networks connected to each other through Network Access Points or NAP's. Backbones, or fibre optic trunk lines, carry the information through routers, or specialised computers which sort and determine where to send your information.
There is one practice that really irritates me during my morning commute to work in downtown Phoenix, Arizona, are the drivers who are in the “fast lane” without keeping pace with the other cars sharing the lane, and who are also failing to yield to a faster driver and allowing them to pass. The passing lane is commonly referred to as a "fast lane" because it is often used for extended periods of time for through traffic or faster traffic. In theory, a passing lane should only be used for passing, thus allowing, drivers to travel at their own pace. There are three important reasons why I believe law enforcement should spend more time ticketing drivers that impede traffic flow instead of ticketing the ones exceeding the speed if conditions warrant because the people going slow are the one’s causing the root problem and the people being erratic trying to get around are only responding to the improper use of the passing lane, making them victims and not perpetrators.
This report will describe the two forms of data communications in terms of the physical interfaces and modes of operation. It will describe the features of data communications equipment in relation to synchronous and asynchronous communication including modems, network terminating units and sending and receiving equipment.
Identify three different Internet Service Providers and compare and contrast – Connection methods – cost comparison.
Now we will discuss some of the key components of any telephone network. These components are loops, lines and trunks. “Loop transmission facilities connect switching systems to customer premises equipment throughout the serving area. A loop is a transmission path between a customer's premises and a local exchange carrier (LEC) central office” (Loop Transmission). A line is a communication connection between your telephone and the local phone company’s switch, such as a PBX or a CO switch. No that we know that a line connects a telephone to the switch, the next stage is the trunk. A trunk is a shared communication channel that connects multiple telephone switches together and has the ability to transfer a telephone call from one location to the next.
Over time the different means of receiving the internet have changed several years ago, a phone line would proved a slow connection to the internet, but would not be useful when storing and...
computer architecture Computer architecture covers the design of system software, such as the operating system (the program that controls the computer), as well as referring to the combination of hardware and basic software that links the machines on a computer network. Computer architecture refers to an entire structure and to the details needed to make it functional. Thus, computer architecture covers computer systems, microprocessors, circuits, and system programs. Typically the term does not refer to application programs, such as spreadsheets or word processing, which are required to perform a task but not to make the system run.
