Module 1 Section 1 1.2 Â Â Â Â Â Â Â Â packet and ironwargon Hardware: the physical components of your ready reckoner: the box and its contents (microprocessor, great(p) disk, fine art card, etc.), to bugger offher with the monitor, keyboard and mouse. Hardware includes components called: Â Â Â Â Â Â Â Â Peripherals: Separate ironware items that are added onto the basic computer unit, such as the monitor, modem, printer, keyboard.

In math the term binary is used to refer to a enumerate system which has only two digits, that is 1 and 0.Any human activity from the decimal system can b e represented in binary; 0 in denary is 0 in! binary. likewise 1 in denary is 1 in binary. When you get to 2 in denary you have a problem. How do you represent two? You simply create a new column and start afresh, using 1 and 0, so 2 in denary becomes 10 in binary. When you apparent movement on to 3 (in denary) you proceed as before; 3 becomes 11 in binary. The table below will explain a bit in another way. The difference among entropy and instructions: Data: is the current... If you want to get a full essay, devote it on our website:
