Reasons I Hate computer technology invention of computers has made life quite comfortable for people all around the world as everything seems to be now only a click on away. RAM is constructed with a few chips packaged together onto a little card known as a DIMM that plugs into the motherboard (twin inline memory module). Here we see the RAM DIMM faraway from its motherboard socket. This can be a 512MB DIMM constructed with 4 chips. A number of years earlier, this DIMM might have required eight chips with the intention to retailer 512MB. Moore’s law in action.

This can be a laborious drive that connects to the motherboard with the seen customary SATA connector. This can be a 160GB, “three.5 inch” drive referring to the diameter of the spinning disk inside; the whole drive is about the size of small paperback e book. This can be a customary disk dimension to make use of inside a desktop computer. Laptop computer computers use 2.5 inch drives, which are a bit smaller.

The transmission media (often referred to in the literature because the bodily medium ) used to link units to kind a computer network embrace electrical cable , optical fiber , and radio waves In the OSI model , these are defined at layers 1 and a pair of — the physical layer and the data link layer.

Workstation computer programs are extra highly effective than most standard desktops. They’re higher-geared up to accommodate high-demand duties like animation, video production, and CAD. Workstations are built to out-perform different machines and to run demanding processes for prolonged periods. You’ll find many workstations function error-correcting code memory, or ECC RAM, for increased reliability; multi-core processors for enhanced processing capabilities; and high-end graphics processing models (GPUs) to reduce load on the central processing unit (CPU). Redundant Array of Unbiased Disks (RAID) is commonplace in workstation computer methods, and refers to utilizing multiple drives for information processing and storage, and mirrored RAID performance protects your data, so if one drive fails, the other retains your data.

Scanners with optical character recognition can read printed material and store it electronically on computers, where it may be read using speech synthesis or printed utilizing Braille translation software and Braille printers. Such methods present unbiased access to journals, syllabi, and homework assignments for college students who are blind. Electronic versions of documentation can support computer users who are blind whether it is delivered in an accessible format.
