,cache special memory section that computer use for frequently required instruction
the kernel is the central (core) component of most computer operating systems
(files/memory/device); it is a bridge between applications and the actual data
processing done at the hardware level
virtual memory used when ram is full
sometimes its slows down computer system
bit (b) a single binary digit, a 0 or 1
storage medium data that is stored example: hard drive, magnetic stripes (credit cards, etc) DVD,
etc.

storage medium
storage device an equipment for recording a copy of the data to be stored.
memory chips =RAM
this are the most important temporary storage unit of data
motherboard is one of the most essential part of the computer.
it holds crucial computer components such as: CPI, memory connector for input and
output
RAM (Random Access Memory) storage location for data in a computer
typically holds program instruction for open applications and the operating system.
Typically found in circuit board. Intended only for immediate need of computer.
ROM (Read Only Memory) Does not disappear if computer is unplugged.
It cannot be altered. retains its contents even when the computer is turned off.
, binary which consists of just two unique numbers, 0 and 1. The base-2 numeral system is
a positional notation with a radix of 2. Each digit is referred to as a bit.
Machine language lowest level language.
a computer programming language consisting of binary or hexadecimal instructions
that a computer can respond to directly.
ISDN (Integrated Service Digital Network) a set of communication standards for simultaneous digital transmission of voice,
video, data, and other network services over the traditional circuits of the public
switched telephone network.
Don't require modem.
Cable Internet digital data transmitted by coaxial and fiber optic cables.
Cable Modem enables transmission of digital data over lines previously used exclusively for cable
TV.
network bridge that provides bi-directional data communication via radio frequency
channels on a hybrid fibre-coaxial and radio frequency over glass infrastructure
Satellite Internet Services refers to Internet access provided through satellites. In other words, it is a
telecommunications network provided by orbital communication stations. Signals
from these satellites allow a user with a dish to have a high speed internet
connection.
IP Address a unique string of numbers separated by periods that identifies each computer
using the Internet Protocol to communicate over a network.
