2. MULTICORE TO CLUSTER Parallel circuits processing, symmetric multiprocessor, or multiprocessor: in the PC has been used in high end serves and workstation for some time. The divide and conquer parallel processing techniques used in multicore PCs are applied on a much large scale in high end serve systems Instead of adding more cores to a CPU, a large system might simply add more machines to a network The processing resource of multiple serves can be grouped together in a cluster.

3. COMPUTER´S MEMORY The CPU’s main job is to follow the instructions encoded in programs, the CPU can handle only one instruction and a few pieces of data at the time The computer divides each RAM chip into many equal-sized memory locations The central processing unit, is hardware component that executes the step on a software program The CPU contains the circuitry to perform a variety of simple tasks called instructions All computer programs are composed of instructions drawn from this tiny vocabulary.

4. COMPUTER´S MEMORY The actual execution of an instruction is performed by the CPU’s arithmetic logic unit. The ALU include registers, each usually 32 or 64 in bits in size. The prefetch unit, instructs the bus unit into reads the instructions stored at the particular memory address. This unit fetches not only the next instruction to execute but also several sequent instruction.

6. How memory works Memory is the work area for the CPU, for the CPU to execute instructions or manipulate data. These instructions or data must be loaded into memory The CPU can store information into RAM and retrieve information RAM may include, program instructions, numbers for arithmetic, codes representing text characters etc… RAM chips are usually grouped on small circuit boards called dual in line memory modules

7. Buses,parts and perripherals A computer typically has a variety of ports to meet diverse needs: one or more video ports of connecting monitors, audios jack, for connecting speakers and headphones Portable computers don’t have room for full- sized cards, many have slots for Express Cards or PC Cards In a desktop computer, the CPU memory, chip, and other key components are attached to the motherboard Information travels between components on the motherboard through groups of wires called internal buses or buses Buses connect to storage devices in bays open areas in the system box for disk drives and other devices.

8. TOMORROW´S COMPUTER In the early days of the PC, chip designers empathize speed because of the growing appetite for computer power Today's cutting edge chips employ nanotechnology, technology that approaches the molecular or atomic level. Nanotechnology breakthroughs may be stepping stones on the road to quantum computer: computers based on the properties of atoms Optical computer: which transmits information in light waves rather than in electrical pulses.

9. THE CLOCK OF THE LONG NOW The clock’s works consist of a binary digital- mechanical system which is so accurate and revolutionary that we have patented several of its elements Long now added a “library” dimension with a realization of need for content to go along with the long-term context provided clock The point is to explore whatever may be helpful for thinking, understanding, and acting responsibly over long period of time

10. Questions Do you think the Long Now Clock is a good idea? Why or why not? Yes, it is easier to use

11. Can you think of the other ways to encourage long- term thinking? Computers.
