Harlem Internet Computer Access Program

Merle Bush, Educator/Author/Project Facilitator

Welcome to HICAP's Virtual Learning Lab brought to you in part through awards from the Internet Society and local officials. Here we share and demystify all the technological data garnered throughout the years.

Your enrollment in the Harlem Internet Computer Access Program marks one of the most important and significantly rewarding decisions of your life. Notably, computers and the Internet have permeated almost every aspect of modern existence. Although this technology is constantly evolving, what we will explore in HICAP is absolute.

Intro Discussion A³

The computer is a memory device. Each keystroke consumes one byte of information. There are eight bits to a byte. A bit is either a zero or a one. Zero means off and one means on. The ASCII Conversion Table shows the exact bit to byte combination that produces every character on the keyboard. The very top row of F keys on the keyboard, we call Function Keys. They used to be programmable, but they are currently programmed by the manufacturer.

In further discussions, we will explore the following:

data = information

            There is a minimum transfer rate for Broadband

            information = words, pictures, music, voice, video

computer = memory save/record data

            Binary Code—0 and 1; i/o; off/on; land/launch—the language computers understand

drives = store information

                        permanent memory = C: Drive

USB Drive® USB Port

RAM is random access memory when your are utilizing the Internet and is not permanent memory

keystroke = consumes one byte of memory

            ASCII Conversion Table—keystroke complement on the keyboard

Internet = send and receive transmitted data

Cloud Computing—saves remotely through the Internet

Acronyms and/or abbreviations: sms-small messaging service and mms-multimedia messaging service

Scientific Notation—manipulates very large and small numbers with the use of exponents/powers

B to the power of n, where n means the number—Bⁿ

1=prime

2=square

3=cube

Byte = memory (suffix) 

Hertz = speed or frequency (suffix)

Preceded by the following prefix to create computer values. Example: 70 Kilobytes--70kb

kilo

—1,000     mega—1,000,000       giga—1,000,000,000              tera—1,000,000,000,000

3 zeros              6 zeros                         9 zeros                                     12 zeros
