If you are one of those lucky PC buyers who got a technical reference book or at For example, in this book information about PC hardware is given in the. Tools for teaching computer networking and hardware concepts / Nurul Sarkar, editor. Summary: "This book offers concepts of the teaching and learning of.
Prominently, one of the chips is covered with a copper "heatsink".. Here the mechanism is released so the CPU can be picked up.
Hardware/Software Components and Applications of BCIs
The fingernail sized CPU is packaged underneath this metal cover which helps conduct the heat from the CPU up to its heatsink. The gray stuff on the metal chip cover is "thermal paste", a material which helps conduct heat from the chip housing to its not shown heatsink. CPU chip in metal package Heatsink has been removed Bottom of package..
Each pad is connected by a very fine wire to a spot on the silicon chip. Here is a picture of another chip, but with the top packaging removed. You see the pinky-fingernail silicon chip at the center with the tiny transistor details etched onto it. At the chip edge, see the very fine wires connecting parts of the chip to outside pads CC licensed attribution sharealke 3. Moore's law in action.
This is a hard drive that connects to the motherboard with the visible standard SATA connector.
This is a GB, "3. This is a standard disk size to use inside a desktop computer.
Laptop computers use 2. This is also known as a "thumb drive" or "USB key". It is essentially a USB jack connected to a flash storage chip with some support electronics: Flash drive the other type of persistent storage i. This chip can store about 1 billion bits.. It's very similar to the USB flash drive, just a different shape. The most popular are probably CD and DVD drives which almost every computer these days has at least one of.
There are some new disc drives such as Blu-ray which can hold a much larger amount of information then normal CDs or DVDs.
One type of removable media which is becoming less popular is floppy disk. They are inexpensive but also have short life-span.
There are a few different kinds of CDs. CD-ROM which stands for Compact Disc read-only memory are popularly used to distribute computer software although any type of data can be stored on them. CD-R is another variation which can only be written to once but can be read many times.
Computer Hardware Books
CD-RW rewritable can be written to more than once as well as read more than once. The CD writer drive can read and write a CD. Both kinds of CD drives are called optical disc drives because the use a laser light or electromagnetic waves to read or write data to or from a CD.
The main uses for DVDs are video and data storage. Most DVDs are of the same dimensions as compact discs. Just like CDs there are many different variations.
Its main uses are high-definition video and data storage. Blu-ray discs have similar devices used to read them and write to them as CDs have. Floppy disks are read and written by a floppy disk drive.
Floppy disks are a dying and being replaced by the optical and flash drives.
Many new computers do not come with floppy drives anymore but there are a lot of older ones with floppy drives lying around. While floppy disks are very cheap the amount of storage on them compared to the amount of storage for the price of flash drives makes floppy disks unreasonable to use. There are a few different types of internal storage.
These are used to hold the data binary information that are being processed by the current instruction. C Memory Primary memory is memory that is part of the computer itself and necessary for its functioning.
As soon as the machine is switched off, data is erased.
RAM is volatile. Volatile means that the data stored in memory is lost when we switch off the computer or if there is a power failure.
There are different types of RAM available. Some of them are described below. The term dynamic indicates that the memory must be constantly refreshed or it loses its contents. This type of memory is more economical. The term static is derived from the fact that it does not need to be refreshed like DRAM.
This type of memory is non-volatile. The information is stored permanently in such memories during manufacture. A ROM, stores such instructions that are required to start a computer. This operation is referred to as bootstrap. The different types of ROM are given below. The MROM cannot be programmed by the user.
EPROM is erased by exposing it to ultra-violet light for a duration of up to 40 minutes. It can be erased and reprogrammed about ten thousand times.
Both erasing and programming take about 4 to 10 milliseconds. Secondary Storage External Storage Devices Floppy diskettes, hard disk, tapes and optical disks come under the category of external storage devices or ancillary storage devices.

These devices are very sensitive to environmental conditions humidity and temperature as well as to external magnetic fields and need to be stored carefully. Information on a floppy disk is recorded in the magnetized states of particles of iron oxides evenly placed upon concentric circles known as tracks.
It contains a stack of metal platters, each coated with iron oxide, that spin on a spindle and the entire unit is encased in a sealed chamber.
