INFORMATION ON COMPUTER DRIVES!

A hard drive is a data storage. The hard disk was first invented on 13th September. for more info go to http://www.computerhope.com/jargon/h/harddriv.htm

Now I'm going to talk about monitors and how they work!

HISTORY ON MONITORS

Early electronic computers were fitted with a panel of light bulbs where the state of each particular bulb would indicate the on/off state of a particular register bit inside the computer. This allowed the engineers operating the computer to monitor the internal state of the machine, so this panel of lights came to be known as the 'monitor'. As early monitors were only capable of displaying a very limited amount of information, and were very transient, they were rarely considered for programme output. Instead, a line printer was the primary output device, while the monitor was limited to keeping track of the programme's operation.

As technology developed it was realized that the output of a CRT display was more flexible than a panel of light bulbs and eventually, by giving control of what was displayed to the programme itself, the monitor itself became a powerful output device in its own right

NEXT ITS A CPU

WHAT IS A CPU

The CPU (Central Processing Unit) is the part of a computer system that is commonly referred to as the "brains" of a computer. The CPU is also known as the processor or microprocessor. The CPU is responsible for executing a sequence of stored instructions called a program

FACTS ABOUT IPHONES

  1. iPhone kind of changed the way we text. Off-topic, without iPhones, you’d never laugh your lungs out the funny autocorrects in the world.
  2. The iPod changed the way people listened and carried their music and the iPhone gave an extension to this. But with not enough memory (in 8 or 16GB models), the iPhone still lacks the kind of storage an iPod provides but if it did, the iPod line would be long dead.
  3. Apps on the iPhone! Oh boy! At last call, several billion dollars have been spent on apps. Apple’s market share of app downloads is enormous despite the relative popularity of Android smartphones. And there’s just one thing that I can attach to that: iOS apps are far better than most Android apps. May be it’s got to do with the kind of strict rules that Apple enforces. Or may be it’s the kind of design aesthetic that app developers have. It’s both, I guess.
  4. About 49% of the people sell their old iPhones before purchasing new ones! That’s something amazing because you don’t see that for any other phone in particular. Sure, people sell their old phones almost always but for a particular smartphone, the number’s huge. What it shows is that people are willing to get their hands on used iPhones too just because of the name/brand. Of course, that’s because of the quality.
  5. Photos: One of the other things that iPhone revolutionized is photos. With progressively powerful iSight cameras, iPhones simply put strong cameras into people’s hands. And apps like Instagram just changed the face of the world of cellphone photography

MOTHERBOARD

WHAT IS MOTHERBOARD?

Alternatively referred to as the mb, mainboard, mobo, mobd, backplane board, base board, main circuit board, planar board, system board, or a logic board on Apple computers. The motherboard is a printed circuit board that is the foundation of a computer, located at the bottom of the computer case. It allocates power to the CPU, RAM, and all other computer hardware components. Most importantly, the motherboard allows hardware components to communicate with one another.

Below is a picture of the ASUS P5AD2-E motherboard with names of each major component of the motherboard. Clicking on the image below gives you a larger more detailed version of the picture below.

RAM

Random-access memory (RAM /ræm/) is a form of computer data storage. A random-access memory device allows data items to be read and written in approximately the same amount of time, regardless of the order in which data items are accessed.[1] In contrast, with other direct-access data storage media such as hard disks, CD-RWs, DVD-RWs and the older drum memory, the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement delays.

Today, random-access memory takes the form of integrated circuits. RAM is normally associated with volatile types of memory (such as DRAM memory modules), where stored information is lost if power is removed, although many efforts have been made to develop non-volatile RAM chips.[2] Other types of non-volatile memory exist that allow random access for read operations, but either do not allow write operations or have limitations on them. These include most types of ROM and a type of flash memory called NOR-Flash.

INPUTS AND OUTPUTS

An input is data that a computer receives. An output is data that a computer sends.

Computers only work with digital information. Any input that a computer receives must be digitised.

Often data has to be converted back to an analogue format when it's output, for example the sound from a computer's speakers.
