Programming languages

Machine Level Language : This is low level programming dialect. PC or any electronic gadget just comprehend this dialect. i.e. Double number i.e 0 and 1.

Gathering Level Language : This is a low level programming dialect which is changed over into executable machine code by an utility developer alluded to as a constructing agent.

Abnormal state Language : High level dialect is a programming dialect which is effortlessly justifiable/discernable by human.

Mediator : This is a convertor which changes over abnormal state dialect program to low level dialect program line by line.

Compiler : This is likewise a convertor which changes over entire abnormal state dialect program to low level dialect program at once.

Number System

Twofold Number System : It has just base 2 i.e 0 and 1

Linux (Ubuntu ) Desktop Elements

Document Management in Linux (Ubuntu)

PC Security

Infection and worms : These are the PC program which breakdown the PC framework. Infection requires a transporter while worms does this without anyone else's input. Worm does not requires any transporter.

Mocking : Through this, misleading the PC clients and making the trick.

Interruption or Hacking : If a PC is utilized and controlled by unapproved clients then it is called hacking and who does this is called programmer. Fundamental reason for hacking to take the private information or adjust the genuine information.

Foreswearing of Services: The fundamental point of this assault is to cut down the focused on system and make it to deny the administration for honest to goodness clients.

Sniffing : Data can be seen and watched when it sets out one PC to other PC. Age of the Computer Charlse Babbase is known as father of PC he has created first investigative PC in year 1822

Original (1940 – 1955) . Case : Electronic Numerical Integrator and Computer (ENIAC) , EDVAC

Second Generation (1956 – 1965) : IBM 1401

Third Generation (1966 – 1975) : IBM System/360

Fourth Generation (1976 – 1985) : Macintosh 128k

Fifth Generation (1986 - till date) : Super PC

The attributes of PCs that have made them so intense and all around helpful are speed, exactness, ingenuity, flexibility and capacity limit. Give us a chance to talk about them quickly.

Speed

PCs work at a mind blowing speed. A great PC is fit for performing around 3-4 million basic directions for every second.

Precision

Notwithstanding being quick, PCs are additionally exact. Blunders that may happen can quite often be credited to human mistake (off base information, ineffectively outlined framework or broken directions/programs composed by the software engineer)

Industriousness

Not at all like individuals, PCs are exceedingly steady. They don't experience the ill effects of human characteristics of weariness and tiredness bringing about absence of fixation. PCs, hence, are superior to anything people in performing voluminous and dreary employments.

Adaptability

PCs are adaptable machines and are fit for playing out any undertaking as long as it can be separated into a progression of sensible advances. The nearness of PCs can be seen in relatively every circle – Railway/Air reservation, Banks, Hotels, Weather estimating and some more.

Capacity

The present PCs can store substantial volumes of information. A snippet of data once recorded (or put away) in the PC, can never be overlooked and can be recovered quickly
