a ________ is a small, lightweight, power-conserving, computing device that is capable of wireless access
To process data into information, computers need a language they understand. This language, called binary language. , consists of just two digits: 0 and 1. Everything a computer does, such as processing data, printing a report, or editing a photo, is broken down into a series of 0s and 1s. is a representation of a fact, figure, or idea. Data can be a number, a word, a picture, or even a recording of sound. For example, the number 7135553297 and the names Zoe and Richardson are pieces of data. A wireless access point is required for connecting wireless devices to a network. Most home networks rely on one wireless router combination device to fill this role. A home automation controller enables low-power wireless communications with simple, non-data-intensive devices such as light bulbs and locks. One of the most common ways of creating a home network is by using wireless radio signal technology; the 802.11 network as certified by the IEEE. Most wireless-capable residential devices operate at a frequency of 2.4 GHz under 802.11b and 802.11g or 5 GHz under 802.11a. Some home networking devices operate in both radio-band signals and fall within the 802.11n or 802.11ac standards. Wi-Fi is a marketing and compliance certification for IEEE 802.11 technologies.

A small, lightweight, power-conserving, computing device that is capable of wireless access. Products that install and update mobile- device software, backup and restore mobile devices, wipe software and data from devices in the event the device is lost or the employee leaves the company. Such products also report usage and provide other mobile device management data. p. 450. D) Anyone can obtain the source code for a closed source project. Only trusted programmers are allowed to make changes to a closed source project. When you buy an operating system for your personal computer, you are actually buying a software ________. A) license. The term open source means that the source of the code of the program is ____. A) available to the public. B) available for licensing if desired. C) available only to carefully vetted contractors. D) less stable and platform dependent. Available to the public. Files and applications can be quite large, containing thousands or millions of bytes. To make it easier to measure the size of files, we need units of measure larger than a byte. Kilobytes, megabytes, and gigabytes are therefore simply larger bytes. As shown in the table, a kilobyte (KB)
