Programming languages are classified as : 1 Machine language: 2 Assembly language: 3 High level language : MACHINE LANGUAGE  :-   the language of 0s and 1s is called as machine language. The machine language is system independent because there are different set of binary instruction for different types of computer systems . LIMITATIONS OF MACHINE LANGUAGES  : It is very tedious and error prone process of writing programs in machine languages . ASSEMBLY LANGUAGES:    it is low level programming language in which the  sequence of 0s and 1s are replaced by mnemonic  (ni-monic) codes. Typical instruction for addition and subtraction . Example :- ADD for addition , SUB for subtraction etc Since our system only understand the language of 0s and 1s . therefore a system program is known as assembler . Which is designed to translate an assembly language program into the machine language program. HIGH LEVEL L...

Some of these tools don’t have graphical equivalents, while others are just plain faster to use than their graphical interfaces. We can’t possibly cover all the useful commands you can use in the Command Prompt or PowerShell here. We’ll be focusing on commands that should be useful even if you’re not a command-line person. ipconfig – Quickly Find Your...

Fiber optic cable  is one of the fastest-growing transmission mediums for both new cabling installations and upgrades, including backbone, horizontal, and even desktop applications. Fiber offers a number of advantages over copper. 1.  Greater bandwidth Fiber provides far greater bandwidth than copper and has standardized performance up to 10 Gbps. While not currently a standard, these speeds could become a reality in future proposals and ratifications. Keep in mind that fiber speeds are dependent on the type of cable used. Single-mode cable offers far greater distance than either 62.5- or 50-micron multimode cable. In addition, fiber optic cable can carry more information with greater fidelity than copper wire. That’s why telephone and CATV companies are converting to fiber. 2. Low attenuation and greater distance Because the fiber optic signal is made of light, very little signal loss occurs during transmission, and data can move at higher speeds and greater distan...

Why does information travel 'faster' down fibre optic cable than copper wire? As the name suggests, fibre optic technology uses pulses of light to carry data along strands of glass or plastic. It's the technology of choice for the government's National Broadband Network (NBN), which promises to deliver speeds of at least 100Mbps. When we're talking about 'speed' were actually talking about throughput (or capacity) — the amount of data you can transfer per unit time, says Associate Professor Robert Malaney from the  University of New South Wales, School of Electrical Engineering and Telecommunications . And fibre optics can definitely transfer more data at higher throughput over longer distances than copper wire. For example, a local area network using modern copper lines can carry 3000 telephone calls all at once, while a similar system using fibre optics can carry over 31,000. So what gives it the technical edge over copper wires? Tradition...

Whether you’re running a local family business, or need to be connected to customers around the world, having fast, reliable, and secure Internet is essential to operational success. But as a small business owner, chances are you don’t have the benefit of IT gurus to help you understand the pros and cons of popular connection options like fiber optic cable and copper Ethernet cable. So we’re going to give you the background and basics on both, and then put them head-to-head in five BuzzBattle rounds to help you decide which fits your company’s needs best: Ethernet cable or fiber optic cable. Background and the Basics Ethernet Cable Developed by Xerox in the early 1970’s, Ethernet was introduced commercially in 1980. Ethernet is a popular method of networking computers in a local area networks (LANs) using copper cabling. In the past, Ethernet had a reputation for being slower than fiber optic cable, but that has started to change. Ethernet speed was once limited to 10 meg...

Android  is a  mobile operating system  (OS) based on the  Linux kernel  and currently developed by  Google . With a  user interface  based on  direct manipulation , Android is designed primarily for  touchscreen  mobile devices such as  smartphones  and  tablet computers , with specialized user interfaces for televisions ( Android TV ), cars ( Android Auto ), and wrist watches ( Android Wear ). The OS uses touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching, and reverse pinching to manipulate on-screen objects, and a  virtual keyboard . Despite being primarily designed for touchscreen input, it also has been used in  game consoles ,  digital cameras , regular PCs and other electronics. Android 5.0 -  Lollipop Google has announced Android 5.0 Lollipop, and it ushers is a new design language and support for 64-bit devices. It's also the first time Googl...

For the rest of the folk in the world Google has said it will be available for the Nexus 4 , 5, 7, 10 and Google Play edition devices 'in the coming weeks' - so some users should be seeing it show up come November, if not before. HTC has already been in contact, giving the following statement about its forthcoming upgrade to Android Lollipop (formerly known as Android L): "HTC is excited about the new features in Android L and we can't wait to share them with our customers. We are committed to updating our flagship HTC One family as fast as possible. "We will begin rolling out updates to the  HTC One (M8)  and  HTC One (M7)  in regions worldwide within 90 days of receiving final software from Google, followed shortly thereafter by other One family members and select devices." Motorola  has also confirmed  that Android Lollipop will be hitting the  Moto X at some point and OnePlus has committed to bringing it to the  OnePlus One within ...
