很多不同的廠家生產各種型號的計算機，它們運行完全不同的操作系統，但TCP.IP協議族允許它們互相進行通信。這一點很讓人感到吃驚，因為它的作用已遠遠超出了起初的設想。T C P / I P起源于6 0年代末美國政府資助的一個分組交換網絡研究項目，到9 0年代已發展成為計算機之間最常應用的組網形式。它是一個真正的開放系統，因為協議族的定義及其多種實現可以不用花錢或花很少的錢就可以公開地得到。它成為被稱作“全球互聯網”或“因特網(Internet)”的基礎，該廣域網（WA N）已包含超過1 0 0萬臺遍布世界各地的計算機。本章主要對T C P / I P協議族進行概述，其目的是為本書其余章節提供充分的背景知識。

本軟件是關于MAX338, MAX339的英文數據手冊：MAX338, MAX339 8通道/雙4通道、低泄漏、CMOS模擬多路復用器
The MAX338/MAX339 are monolithic, CMOS analog multiplexers (muxes). The 8-channel MAX338 is designed to connect one of eight inputs to a common output by control of a 3-bit binary address. The dual, 4-channel MAX339 is designed to connect one of four inputs to a common output by control of a 2-bit binary address. Both devices can be used as either a mux or a demux. On-resistance is 400Ω max, and the devices conduct current equally well in both directions.
These muxes feature extremely low off leakages (less than 20pA at +25°C), and extremely low on-channel leakages (less than 50pA at +25°C). The new design offers guaranteed low charge injection (1.5pC typ) and electrostatic discharge (ESD) Protection greater than 2000V, per method 3015.7. These improved muxes are pin-compatible upgrades for the industry-standard DG508A and DG509A. For similar Maxim devices with lower leakage and charge injection but higher on-resistance, see the MAX328 and MAX329.

This is an example how one could hide a process on Windows based
operation systems from task viewers like ProcDump (G-RoM, Lorian
& Stone) or ProcessExplorer (SysInternals).
It could e.g. be used as some kind of dump Protection.
The way to get this done is very different on NT and 9x machines.

TION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
WARNING!
Although the AD7008 features proprietary ESD Protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
