What are the chareristics of computer?

Answer 1

1. The CPU (Central Processing Unit). The heart of the computer. This, through the use of millions (and more recently, billions) of transistors (which act as switches, their output either being a 1 or a 0), processes the commands given to it, running the programs the rest of the system requires.

2. The motherboard. This board allows any piece connected to it to access and send information to or from any other piece, and stores the microprograms with which they do so. Everything is either directly or indirectly attached to it.

3. The GPU (Graphics Processing Unit). It is similar to the CPU, but it is entirely dedicated to processing the video output of the computer, and has a dedicated pool of resources, so the task of outputting video is not a drain on the rest of the system.

4. The RAM (Random Active Memory). It is a volume of active memory (meaning it cannot hold information without power) that the system uses to cache the expected, likely, or recently used outputs to specific commands or questions. For example, when using a word processor, it holds all the letters of the alphabet, ready to display them, instead of having to do individual lookups for every time a letter is typed. Or, when running a 3D graphics program, it stores textures so they may be quickly displayed on-screen.

5. The hard drive. This piece passively (doesn't require power to retain) stores information, such as programs or pictures. There are two types of these:

a. The HDD (Hard Disk Drive). The cheaper of the two, it is also the slowest in data read and write times. It employs one or more metal-plated disks, a motor, and an electromagnet (called a head). The motor spins the disks (often in excess of 7000 RPM), and the head is moved over the disk and magnetizes small sections of the disk's surface. Based on the charge, the disk will read either a 1 or a 0, which in long strings is interpreted as data. To read the information back again, the electromagnet lets itself be magnetized by the disk, which generates the previously recorded information.

b. The SSD (Solid State Drive). This drive uses flash memory to store information, the same as their USB-sized counterparts, thumb drives. Instead of a physical disk, this drive utilizes no moving parts whatsoever, relying on small electronic switches to store the 1's and 0's of data. This dramatically improves on the reliability and speed of HDD's, but at a price (literally). SSD's are often $1 per GB (GigaByte, a unit of storage). As comparison, downloaded movies are around 2GBs. As such, at the time of this writing, SSDs are used only in servers, databases, and in heavy gaming computers.

6. The CD (Compact Disk) drive. This works similarly to a HDD, but instead of using magnetization, it uses lasers. The disk is reflective, allowing the laser shined at it to be reflected to a sensor. Information is stored on CDs by creating patches of non-reflective areas, which prohibit the light from reaching the sensor. By spinning the disk around, the drive causes a rapid series of flashes to reach the sensor, which interprets them as the 1's and 0's of data (light is interpreted as a 1, and no light as a 0).

There are various other minor parts to a computer, but they are not major, or are merely accessories. Such things include the mouse and keyboard, the monitor, and the webcam. It is true that without these pieces, the experience of using a computer is more limited, but the lack of them does not inhibit the computer from accessing, processing, or writing the essential information it need in order to run, so they are not listed here.
