The black box in the middle is computer science. Various aspects of Artificial Intelligence can be included in the computer: natural Reliability Computers can carry out same type of work repeatedly without throwing up errors due to tiredness or boredom, which are very common among humans. endobj Memory is an essential component of the computer. Also, data is safe from normal wear and tear associated with paper. The corresponding figure for an actual computer looks something like this , The basic parts of a computer are as follows .

A computer is an electronic device that accepts data/inputs from its user and processes it into useful information as per the processing instructions to generate the output. Computers perform all jobs with 100% accuracy provided that the input is correct. There may be a variety of opinion about the content of the topics, but for the beginner it is the best which gives the time and opportunity to become familiar with the basics before pursuing further into the field of study in greater detail at the upper secondary level. We could start by flipping through the book, one page at a time, until we find Mike Smith or reach the end of the book. . % When we learned to write numbers with the digits 0 through 9, we learned to use decimal.

Computer hardware is the collection of physical elements that constitutes a computer system. endobj First stored-program computer, Made vacuum machine obsolete by the late 1950s, The original transistor-based computers used thousands of discrete components, IC: put many transistors onto a single microchip, This led to cheaper computers and started the minicomputer in the 1970s, IC-based computers were still huge machines, The advent of Very Large Scale Integration (VLSI) technology allowed tens of Starting a computer or a computer-embedded device is called booting. The first program or set of instructions that run when the computer is switched on is called BIOS or Basic Input Output System. A computer is an electronic device, operating under the control of instructions stored in its own memory, that can accept data, process data, and produce results. To understand why computers are such an important part of our lives, let us look at some of its characteristics . The basic parts of a computer are as follows Input Unit Devices like keyboard and mouse that are used to input data and instructions to the computer are called input unit. There are majorly 4-5 types of computers namely PC/Personal Computer, Workstation, Mini Computer, Supercomputer, and MainFrame Computer.

This event is used for our two sprites to communicate with each other, like sending a secret message. Bachelor in technology can get updated and revised notes provided in the article. A good Computer system architecture which can carry out all the above processes the quickest in a sense it should be able to recognize the information fast and be able to process it quickly. This notes were made based off all the lectures for this module. The computer system architecture provides us with a detailed understanding of how a computer software system and a computer hardware system interact with each other to form the entire computer system.

HOW THE COMPUTER WORKS; the computer work when given instructions from the user the instructions initiate four major operation of the computer which are input operation, processing operation, storage operation and output operation. As per our basic knowledge, an electronic device that accepts input/data and processes it into valuable information i.e output is named a Computer. For example, we might want to have Scratch cough three times by repeating some blocks: While this is correct, we can avoid repeating blocks with a loop: The next step is abstracting away some of our code into a function, or making it reusable in different ways.
