Bus and Memory Transfers

BUS If a computer has 16 registers, each holding 32 bits, how many wires are needed to connect every register to every other? (162) For a large number of wide registers, the wires could end up taking most of the space in the circuit.
A BUS is a single shared set of wires connecting all registers.
Memory Transfer The internal bus connects only registers within the CPU, so how do we get data to and from memory?

The address register (AR) is used to select a memory address, and the data register (DR) is used to send and receive data. Both these registers are connected to the internal bus. DR is a bridge between the internal BUS and the memory data BUS.

Memory can also be connected directly to the internal BUS in theory.

M[AR] ← DR DR ← M[AR]   Hence, accessing memory outside the CPU requires at least two clock cycles. First we load AR with the desired memory address, and then transfer to or from DR. In most typical c…

What is the difference between a direct and an indirect address instruction ?

Direct addressing means the instruction refers directly to the address being accessed. That is, the instruction encoding itself contains the address of the location. Depending on the instruction set, it may also allow computing a small index relative to the address. When used that way, you can think of that as a direct-indexed mode. (Note: Some processors call ‘direct’ mode ‘absolute’, such as the 6502.)

Indirect addressing uses an address held in a register or other location to determine what memory location to read or write. The idea here is that the instruction itself isn’t directly telling you the address to access, but rather indirectly telling the CPU where to find that address. The processor may also allow you to add a small offset to the indirect address, giving an indirect-indexed addressing mode.

Google No Longer Lets You Change Domains To Search Different Countries

Google has just announced that it will be changing the way it labels country services in Search. Google had planned to display search results based on user’s location, independent of whichever domain is in use.Google No Longer Lets You Change Domains To Search Different Countries
Google previously provided a useful feature in which it let users change the locale or language. Users just needed to type Google into the address bar with different country code like for India Google.co.in and for United States Google.com.
This feature is useful for people who lived abroad but preferred to have their own search results more tailored towards their home country. For example, if you live in a smaller country, then adding Google.com will deliver better results. However, that feature will go missing from now as Google has just announced that it will be changing the way it labels country services in Search. Google had planned to display search results based on user’s location, indepen…

10 Advantages of Rooting Android devices

10 Advantages of Rooting Android devices

Rooting Android – One of the biggest unique selling points about Android is the fact that it is so flexible and malleable. While Apple’s iOS is workable right off the packaging, it is also more closed in than the Android, which is why Google’s popular operating system has been such a hit among developers. To truly understand just how much you can do with the Android, though, you have to root it.
What does rooting android even mean?

Before we get into the pros and cons of rooting Android devices, let’s look at what rooting android involves. In the simplest terms, rooting means getting root access or administrative privileges for your device. You may have paid for your Android device, but it’s worth noting that no matter how much or how little you pay, the internals of the device are still locked away.

Think of it as operating on a desktop computer through a user account. You get to take advantage of most of the features of the phone,…

Everything you need to know about rooting your Android

While your Android isn't in the same sort of jail an iPhone lives in, rooting can help you break out.

If you've researched anything about Android on the internet, you've probably seen and read about "rooting" one. There was a time when many of the Android phones available didn't live up to their potential, and root was the answer. Horrible software was the norm, applications that you would never use ran amok and wasted data and battery life, and the experience was bad all around.
   Because every Android phone is running the Linux kernel and middleware very similar to a Linux distribution you would install on a computer under the hood, rooting them was the way to allow us to try and fix them our own way. Rooting is how you get complete access to everything in the operating system, and those permissions allow you to change it all. Modern Androids are quite a bit better than they used to be. Even the most inexpensive phone or tablet you can buy in 20…

WhatsApp beta 2.17.397 adds new emojis for fantasy, facial expressions, and yes, T-Rex

While I'm sure very few people have yearned for a broccoli or a cricket emoji on WhatsApp, there are plenty of other emojis that were still missing from the app compared to the Android 8.0 emoji set and Apple's latest set. The monocle, star eyes, swearing face, vomiting face, shushing face, exploding head, and many more were still missing from WhatsApp even when the app revamped its entire emojis early this month and introduced its own set.
  With the latest beta 2.17.397, WhatsApp brings all of these missing emojis to the table. It's true that you could receive these before in conversation, but you couldn't send them and now you can.
   Most of the new emojis are the ones you can see in Emojipedia's list of new 2017 emojis and depicted in the image at the top of this post. (Just forgive the face with the long nose - I thought it was new, but it isn't.) There are new facial expressions, a bearded guy and a woman wearing a headscarf, a breastfeedi…

How to convert a PDF to JPG for easy viewing on any device

How to easily convert a PDF to JPG for easy viewing on any device....
There are plenty of worthwhile reasons to convert a Portable Document Format (PDF) to a JPG image (it’s different from a GIF, you know). Although PDF files are a fantastic way to package a slew of text and image documents together, they often require an external application or plug-in and are unnecessary if you want just a single page or image. But to make that transition, you need to know how to convert a PDF to JPG.
There Are Many Different Ways To Do This , But My Favorite Method using Zamzar — Free web tool



Online tools can typically be used from any computer or mobile device. Since they don’t take up any room on your computer and tend to be speedy little converters, you may prefer them to other options. Their only downside is that they tend to be a little limited in the amount of data you can convert at one time, which makes them difficult to use for larger PDF files.

Still, they can be a useful to…

What Are Animoji?

What Are Animoji? 
Animoji are animated emoji that have been created by Apple for use in messaging.
Everyone loves emoji. What fun would text messages be without being able to flirt with a winky face, invite people to dinner with tacos, or explain just how bad your day was with the pile of poop? But emoji aren't very personal. We use the same emoji every time. But that's about to change, thanks to Apple's new Animoji.


What Are Animoji?
Animoji are a new feature introduced by Apple that transforms some of the classic emoji icons into short, customized animations.
What's particularly cool about them is that they're not just animations. They actually scan your facial expressions and map them onto the icon, so that an Animoji acts out your behavior. Frown and your Animoji frowns. Shake your head, laugh, and close your eyes and the Animoji does the same.
Even better, you can record short voice messages with Animoji and, thanks to the facial scan and expressio…

The Deep Web and Dark Web – What’s Hiding In There?

The Deep Web and Dark Web – What’s Hiding In There?
 I was always told as a content writer when in doubt ‘cut it out’, and generally, as a rule of thumb, that served me well.
 Now, when it comes to things like the Dark Web and the Deep Web, which are not the same things incidentally, I would offer the same kind of advice – meaning stays away if you have no business being there. This advice, gathering from all the horror stuff that’s available on movie sites, will have all heading off to the darkest and deepest webs possible, as fast as possible.
 Fueled by a lot of tabloid-type ‘revelations’ of disappearing Bermuda-triangle style after typing in certain words once you’ve made it to the ‘other side’, or being stalked by a mass of serial killers if you do manage to get there, a lot of the stuff is, well, tabloid-type junk.
 Having said that, a lot of it isn’t. For instance, you can buy guns and drugs (and stuff) there. There’s are things we haven’t seen, so if you are intent…

These Are The Fastest Growing Programming Languages - Tech Trone

These Are The Fastest Growing Programming Languages  A lot of new programming languages are making their way to the top and JavaScript is holding the top position for the past few years. Seems like the situation is about to change and JavaScript may soon be dethroned by Python. Python is one of the fastest growing languages and by 2019, it would have a clear domination in the programming community.
 This is a prediction made by StackOverflow, a programming Q&A center. With more than 50 million amateur and professional developers visiting the website, StackOverflow is one of the qualified companies to make such a survey. Based on the huge increase in the questions from developers on Python and the data they have collected, StackOverflow made this survey possible.
Stack Overflow data scientist David Robinson said in a blog post that, “The term ‘fastest-growing’ can be really hard to define precisely, but we make the case that Python has a solid claim to become the fastest-g…

C++ Classes and Objects - Tech Trone

C++ Classes and ObjectsClass: The building block of C++ that leads to Object Oriented programming is a Class. It is a user defined data type, which holds its own data members and member functions, which can be accessed and used by creating an instance of that class. A class is like a blueprint for an object.
     For Example: Consider the Class of Cars. There may be many cars with different names and brand but all of them will share some common properties like all of them will have 4 wheels, Speed Limit, Mileage range etc. So here, Car is the class and wheels, speed limits, mileage are their properties.
 A Class is a user defined data-type which have data members and member functions. Data members are the data variables and member functions are the functions used to manipulate these variables and together these data members and member functions defines the properties and behavior of the objects in a Class. In the above example of class Car, the data member will be speed limit
