Memory Management Techniques
Computer must require some memory to store the data, doing some process and for generate some output. Many years ago when RAM (Random Access Memory) is considered as a main memory at that time some problems were came.
RAM has two drawbacks 1. Speed
2. Capacity
Speed in comparison with the processor and capacity in comparison with Hard Disk Drive (HDD). To reduce this drawback some memory management techniques were invented. Some of them written below.

- Instruction Pre-fetch
- Write Buffer
- Memory Interleaving
- Cache Memory
- Virtual Memory

"Let's start Processor Architecture Utility with Basic"
As we all know that it stared from Computer Organization. So how computer is organized, with the input, process, memory and output. So first we should know about all the latest input devices which are used to give some input like data or instruction to computer.
Keyboard, mouse, scanner, web-cam, etc.But we should know further or above it. If you want to watch some of the videos about emerging new input devices, you should watch this videos.
Any machine that feeds data into a computer. For example, a keyboard is an input device, whereas a display monitor is an output device. Input devices other than the keyboard are sometimes called alternate input devices. Mice, trackballs, and light pens are all alternate input devices.
Joysticks were once the king of gaming input devices. The advancements of the mouse have taken over a lot of the jobs it once held. Now, joysticks are used mostly for flight or space simulations.
A basic joystick consists of a hand held stick that can be tilted in 360 degrees, and sometimes twisted left or right. Joysticks that are made for flight simulators will normally come with a separate controller for the throttle controls.

Get ready to cast aside your keyboard and mouse. Future computer input devices will rely heavily on the movements of our eyes, head, hands, body and the words that we speak. But are you ready for a computer that can read your mind? let's check out the latest developments in computer-human interaction...
The most fantastic of all future input devices has to be the brain wave detection input device. To use this device you will simply have to think about what you want your computer to do and the computer will respond accordingly. It will have sensors that will be able to receive your brain waves and interpret them as a computer command. Can you imagine, composing a term paper or business report just by thinking about what you want to write? Already there are some devices that use EEG and biofeedback technology to detect brain waves and create brain-computer interfaces.

Wacom has announced their latest tablet input device, the Vista-certified Bamboo (~$75). It will make a nice sidecar to a Microsoft WED 8000 keyboard (when it comes out in September). It’s not so much about art or design, it’s much more utilitarian than that. The pen is, by a vast margin, the fastest input device I’ve found (second only to knowing keyboard shortcuts). Once you get over the learning curve and eye-hand coordination, you can navigate your desktop in record speed.

Input Devices of the Future

But are you ready for a computer that can read your mind? let's check out the latest developments in computer-human interaction...Body Movement Input Devices
Body movement input devices are perhaps the easiest step to take in terms of evolving input device technology. These devices will track eye, foot or body position with a magnetic tracker or 3D tracker and mirror those movements on your computer screen. These devices are already in development, and some demographics are already using them. For example, people with mobility disabilities like paralysis or MS, can use head position trackers to help them use their computers.Brain-Computer Interface Devices

SplitFish's EdgeFX controller brings PC-style input to the console
The evolution of input devices for gaming consoles has certainly been interesting to follow: from Atari's paddles and joysticks to Nintendo's classic NES controller to the modern million-button joypads which delight children and confuse adults, developers are forever seeking ways to increase both the functionality and ergonomics of these peripherals.
