Beginners Basic Computer Guide

Computer is an electronic device which is designed to work with information. The word 'computer' comes from the Latin word 'computer', it means counting or programmable machine. The computer can do nothing without a program. It represents a decimal number with a string of binary numbers. The term 'computer' usually refers to central processor units plus internal memory.

According to functionality, computers are classified as:

  • Analog Computer: A computer that represents numbers by constantly changing physical volume, whose variations imitate the model of some system models.
  • Personal computer: A personal computer is small and low cost in a computer. The term "personal computer" is used to describe the desktop computer (desktop).
  • Workstation: A network terminal or desktop computer. In this context, the workstation is just a general term for a user machine (client machine) in contrast to a "server" or "mainframe".
  • Minicomputer: A minicomputer is not too short. At least, most of us do not think about Mini. You know how big your personal computer and its related family are.
  • Mainframe: This is a large computer that operates a whole corporation.
  • Supercomputer: It is the world's largest, fastest and most expensive computer.
  • Microcomputers: Your personal computer is a micro computer.

Basic parts of a computer:-


A computer monitor is an output device that displays information in the graphic form. A monitor usually consists of display devices, circuits, casing, and power supply. Modern monitors display devices typically replace a cold-cathode fluorescent lamp (CCFL) backlit, with a thin film transistor liquid crystal display (TFT-LCD) with LED backlighting. The older monitor uses a cathode ray tube (CRT).

The HDD:-

On the other hand, Hard Disk Drive (HDD), part of your computer is responsible for "long-term" memory. Hard drives use magnetic storage to write "fixed" data. We want to say strongly that if you close your computer the information will still be stored on the hard drive and you are ready to access it after you retrieve it.


There are two parts of your computer that are responsible for memory. Let's look at the random access memory (or RAM) early. Ram is a small stick with plastic circuits with several contacts on one side. It plugs directly to the motherboard of your computer (the large platform of the platform which plugs to other parts of the computer). Your computer's RAM somewhat like your short-term memory. It contains everything that a computer is thinking about right now.


Central processing unit (usually referred to as CPU) has a four-square-inch chip inside your computer, which has millions of transistors, which can perform every single mathematical operation. CPU Central Processing Unit Your computer's CPU is pretty cool in your computer's brain. This is part of your computer that is "Thinking", in the form of millions of calculations per second. On this day, the CPU creates several "core" that can work together.

CCleaner: Is It a Safe Software?

CCleaner is a free anti malware tool. The same was developed by a Company which is based in London, known as Piriform. The anti malware tool was recently damaged which affected over 2 million users worldwide. The developer company is presently owned by renowned software security firm Avast.   

The company says that its download servers were compromised with during some time after the 15th of August this year shortly after it released its version v5.33.6162 . This happened owing to a data leak which also led to the injection of the second malware payload into the use PC to affect the same in the long run.

About CCleaner

CCleaner has over 2.27 million users globally. It has already been noted in the past that these hackers could do anything to earn street credit cards and money. Experts feel that is a form of industrial espionage which could ultimately destroy a country’s defense. 

It is being assumed that this was one of those attacks or it can be just for fun. It could also be just to show a large company like Avast that their security is breakable. However the exact reason for this hacking attack is yet to be known.

The virus attack: it’s impact

Researchers in the field are of the opinion the CCleaner malware was particularly worrisome because it somehow made it onto software that could be executed using Piriform’s valid security certificate. They also feel that the malware which was used is almost undetectable one out of 64 antiviruses can detect its presence.

It was also noted by the research team that this was the same malware that created the chaos on June, 2017. The attack back then had crippled thousands of business machines worldwide. The wiper malware was used for doing this attack back then. The same  was distributed from a legitimate tax accounting software from Ukrainian company M.E.Doc.

Steps to resolve the problem

“Piriform” has promised to fix this on the next version 5.34 which will be available on their official website.
However the big question here is who hacked the software? Was something which was done hackers or was it inside job? Or could it just be a publicity stunt? The fact is that if it was an attack from outside, then the company would not be so very concerned with the issue .Of course this type marketing is quite common with many companies.
As per the company, it is taking many corrective steps internally so that these incidents do not get repeated in the future. However this incident only is another reason why you as an internet user must be more cautious from here on. The following are certain steps you could use in this direction:
  •         You must try using strong passwords always
