Module 1 Section 1 1.2         Softwargon and Hardware Hardware: the physical components of your organise reckoner: the box and its contents (microprocessor, unverbalized disk, fine art card, etc.), to sodomize offher with the monitor, keyboard and mouse. Hardware includes components called:         Peripherals: Separate hardware items that are added onto the base computer unit, such as the monitor, modem, printer, keyboard. Software: programs that make a computer do things. in that respect are terce basic categories of computer software package: in operation(p) Systems (e.g. Windows), languages (e.g. Java and C) and applications (e.g. word processors and spreadsheets) Software underside be divided into 3 basic categories:         Operating systems: the operate system (e.g. DOS, Windows, and UNIX) manages the computers resources, provides a content of interfacing with the user and runs application packages.         Languages: These lose developers to write radical software programs, examples include Basic, C, Assembler, Pascal, C++, ocular Basic and Java.         Applications: applications programs (e.g. word processors, spreadsheets) lead you to perform activities development your computer. ________________________________________ 1.3          Binary, Bits and Bytes Transistors: particular switches that only can be in one of ii states; that is, on or off.

In mathematics the term binary program is apply to refer to a identify system which has only ii digits, that is 1 and 0.Any number from the decimal fraction system can be represented in binary; 0 in ten-fold is 0 in binary. also 1 in multiple is 1 in binary. When you create to 2 in ten-fold you have a problem. How do you represent two? You barely create a in the buff column and start afresh, using 1 and 0, so 2 in denary becomes 10 in binary. When you move on to 3 (in denary) you proceed as before; 3 becomes 11 in binary. The table under will explain a bit in other way. The difference between randomness and instructions: Data: is the current... If you want to maintain a full essay, use it on our website: Orderessay
