What is Software



What is Software? Software is the collection of programming instructions with the purpose of task completion. It can again be refers of set of machine readable instructions that can control the processor and other hardware to accomplish an operation or task. Impact software is anything that exist in electronic devices that human cannot see physically, feel or touch in any way but can see its impact in todays life.

Software is not limited to what we always think ie computer or phones, rather software is present in almost everything that can manipulate itself electronically. Software can be found on television, Cars, digital watch, fridge (fridge? Yeah we have smart fridges and even digital ones), radio and many electronic devices.

Types of Software

• System Software
• Application Software

People do get confused what about the difference between the duo! I will try as much as I can to break things and by the grace of God after finish reading this article you will never be confused again!

System Software

Let me start by defining what is a system. A system is a collection of software and hardware to perform a task. Don't bother much about the hardware as for now, will treat it in a different article. As for now take hardware as anything in a system that human can touch and feel. System can again be seen as the integrating of interrelating or independent components to form a whole organization with the purpose of completing a task or delivering a particular service.

System software is any software that runs within the system, which the system cannot do without! Lets take for example A human system. Wait!!! thought you said electronically! Yeah! But don't you know human-beings are systems too! How? Humans comprises of software and hardware! Our soul can only be imagined but never seen, this is an example of human software while the body eg head, hand, legs, intestine can be seen as human system hard... ohk! Human soul in the body is the main system software! Without soul the body is as good as nothing! The body cannot manipulate itself without soul, what happen when human dies can be seen as the absent of the human soul in the system. Which we all know

That's exactly what happens on computer systems or any other electronic device. Electronic devices without the system software are as good as nothing! The main basic types of system softwares are:-
• Firmware
• Operating system OS

Firmware:- This can be seen as the most basic piece of software which controls everything a hardware is. Sometimes we get confused between what OS and  firmwares are. Think of a computer without a hard-drive can that computer power up? Searching your database for answers...... yeah definitely that computer will surely come up! Wait! How and why? Ok open your computer and try it! I didn't send you! Before police will arrive at my door, because I made you caused damage on your device! Laughing..  joke apart it will surely power up! The reasons are simple! When user press the power key, after electronic signals trigger and starts anything that needs power, the processor will first check if the RAM random access memory is present, then go to flash memory where the firmware is stored, copy it and load it on RAM. Its a hardware so no need for it as for now we shall discuss them in the hardware article just stay tuned). If no firmware is present systems cannot startup! So basically the Firmware is the soul of every system. Without Firmware there will surely no electronic systems. Just like I have already said human being is as good as nothing, impact its called dead without the soul.

Microsoft Office for Tablet now on Google Play store

Back in November, Microsoft opened up early previews builds for its new mobile Office applications for Android tablets to those willing to sign up and wait for an invitation. After taking on feedback over the past couple of months, Microsoft has announced that it is expanding its preview scheme by releasing its Office applications to everyone directly through the Google Play Store. The new Office software for mobile unifies Android, IOS, and Windows platforms. Previously each platform had to make do with its own apps, meaning that feature sets differed depending on your operating system and updates were often slow and intermittent. By unifying the Office platform, Microsoft hopes to bring updates and new features to users in a timelier manner. There are still a couple of conditions attached to the preview builds though. Firstly, Office is still limited to ARM-based Android tablets with a screen size between 7 and 10.1 inches. Your tablet will also need to be running Ki...

iTunes Connect is down!

Something is wrong in Cupertino. A number of developers today turned to Twitter to complain that iTunes Connect, a hub for iOS and Mac software makers, was logging them into the wrong accounts.  The service appears to be matching log-ins with the wrong accounts, showing apps and usernames from completely different people. When developers try to access one of the apps, they receive an error message leading them back to their own account. iTunes Connect has since been taken offline as Apple’s engineers presumably set off to fix the problem. We’ve contacted Apple and will update if we hear back. Culled from:  The Next Web

Ethical Hacking Simplified. Applications of Cryptography

Pretty good Privacy PGP This type of cryptographic Application uses Public key encryption system and  is one of the most popular means of encryption in the world. It is used in securing data, data storage, email, Instant Messaging (instant messaging are messaging system that happens in real time, just like whatsApp, Facebook messenger etc.) and other forms of communication. The early version of this cryptographic application was written by Philip Zimmerman and has it public appearance in 1991. it is part of an open-source project with many version where user can choose the best that suit them. This cryptographic application comes with privacy and security measure that are found in many online systems. The data will travel in an encrypted form (chipertext), upon arriving at the receiving end, the receiving will use PGP to decrypt the data back to plaintext. PGP uses the Public/Private key encryption. Where the sender uses his public key to encrypt data, and the receiver ...
