Document Summary

Resolution: di(cid:373)e(cid:374)sio(cid:374)s of the displa(cid:455), reported as (cid:862)(cid:894)(cid:374)u(cid:373)(cid:271)er of pi(cid:454)els (cid:449)ide(cid:895) (cid:454) (cid:894)(cid:374)u(cid:373)(cid:271)er of pixels tall, typical resolutions. Density: so(cid:373)eti(cid:373)es, size a(cid:374)d resolutio(cid:374)s are (cid:272)o(cid:373)(cid:271)i(cid:374)ed i(cid:374) si(cid:374)gle (cid:862)pi(cid:454)els per i(cid:374)(cid:272)h(cid:863) (cid:894)ppi(cid:895) measure. Most modern displays use a lcd panel and light emitting diodes (leds) to produce the image on screen. Accurate reproduction of fast moving images (e. g. gaming) Colours appear distorted when viewed from off-centre angles in plane switching. Better reproduction of colours, especialy when viewed from angles. Units of speed and space: processing speed. Base unit: hz = cycles per second: storage space. Base unit: byte = 8 bits: measuring in base units are impractical in contemporary computing, so they are combined with metric prefixes to represent larger magnitudes. Central processing unit (cpu: brains of computer, decodes instructions and carries out the corresponding arithmetic, logic or control operations. Components of the cpu: control unit (cu): Coordinates the flow of instructions and data between the other components of the cpu.
