Hello Everyone! 
Today's article focuses on a very HOT topic! GRAPHIC CARDS! Who doesn't want the very best silicon out there to ramp up the effects and smoke the latest titles like Batman: Arkham Origins, Battlefield 4, Splinter Cell, Crysis 3, The Witcher and tons of other games out there! So if you're going to bake in a new graphic card into your Computer chassis, this guide will guide you all you need to know before buying a new Graphic Card! Ride Along! 

Polynomials in MATLAB

Expressions that contain some number of variables and constants combined using operations such as addition, subtraction, multiplication and whole-number exponents are called POLYNOMIALS.

For example,

x² + x + 1, x³ + x² + x + 1

In MATLAB, polynomials can be represented as row vectors.

To declare a polynomial, say P(x) = 3x² + 2x + 1, we use:

P = [3, 2, 1];

Or

P = [3, 2, 1];

Note that the coefficients of the variables are taken in the row vector and not the powers.

To declare a polynomial such as Q(x) = 13x³ + 4, we use

Q = [13, 0, 0, 4];

(Because 13 x³ + 4 can be written as 13x³ + 0x² + 0x + 4.)

Networking Hardware

In the smooth functioning of networks, many hardware devices play an important role. These hardware devices, or in other words, Networking hardware may also be known as network equipment or computer networking devices. Hence we’ll be studying a few of them in the following sections. All these devices facilitate the use of a computer network. Specifically, they mediate data in a computer network.

Unguided Transmission Media

Hey!

I do hope you read my articles on Guided Transmission Media and Types of Transmission Media before coming to read this. If not, I'd strongly recommend you to see them.

Back to the things that matter, Unguided Transmission Media! These are transmission media that are used for used when either the distances are HUGE, or the communications need no security of any kind because these forms or communications are relatively insecure as compared to Guided Transmission Media, or, the communication is a form of broadcast and needs to be sent to many people at the same time. The signals travel through Air, Water or Vacuum. As an example, the WiFi Internet Access that you enjoy happens because of a WiFi Chip in your device AND, the radio signals that spread out from the router antennae. As a general rule of thumb, anything that involves "waves" as a form of propagation media (radio waves here) are a form of unguided transmission media. So lets delve into the related technologies.

Types of Unguided Transmission Media we're going to study in this article:

1. Radio Waves
2. Satellite Microwave
3. Terrestrial Microwave
4. Infrared

Hence lets get started.

Vectors and Matrices in MATLAB

Matrices are the basic data elements in MATLAB. This helps to make the code shorter and easier to understand as it reduces the number of loops and repeating statements. Single variables are treated as a matrix of a single element, also called scalars.

To declare a vector in MATLAB,

A= [10 34 29]; %row vector (1, 3)                                    

Or

B = [114, 09, 46]; %row vector (1, 3)

Or

C= [101; 900; 20]; %column vector (3, 1)

Or

D= [1, 2, 3; 4, 5, 6; 7, 8, 9]; %3x3 Matrix

Guided Transmission Media

Hey Folks!
Today this post would be, as I said in my last post, about Wired/ Guided Transmission Media Technologies. As a plain fact to remember, guided media are those where the transmissions they carry can be guided. The Ethernet cable that connects to your PC Modem? That's an example of Guided Transmission Media. The Music Player in your car that plays up songs for you from the local radio? NOT an example of Guided Transmission Media. In this case the radio waves are spread throughout the atmosphere and your car just receives and plays that signal. The others going around with you can play the same signal. There is no amount of direction given to these signals and are just spread out for our equipments to receive.
In general, any type of wired transmission media can be safely assumed to be an example of Guided Transmission Media.

There are several types of Guided Transmission Media. Let us study them one by one.
