很多不同的廠家生產(chǎn)各種型號(hào)的計(jì)算機(jī)，它們運(yùn)行完全不同的操作系統(tǒng)，但TCP.IP協(xié)議族允許它們互相進(jìn)行通信。這一點(diǎn)很讓人感到吃驚，因?yàn)樗淖饔靡堰h(yuǎn)遠(yuǎn)超出了起初的設(shè)想。T C P / I P起源于6 0年代末美國(guó)政府資助的一個(gè)分組交換網(wǎng)絡(luò)研究項(xiàng)目，到9 0年代已發(fā)展成為計(jì)算機(jī)之間最常應(yīng)用的組網(wǎng)形式。它是一個(gè)真正的開放系統(tǒng)，因?yàn)閰f(xié)議族的定義及其多種實(shí)現(xiàn)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(lián)網(wǎng)”或“因特網(wǎng)(Internet)”的基礎(chǔ)，該廣域網(wǎng)（WA N）已包含超過1 0 0萬臺(tái)遍布世界各地的計(jì)算機(jī)。本章主要對(duì)T C P / I P協(xié)議族進(jìn)行概述，其目的是為本書其余章節(jié)提供充分的背景知識(shí)。

本軟件是關(guān)于MAX338, MAX339的英文數(shù)據(jù)手冊(cè)：MAX338, MAX339 8通道/雙4通道、低泄漏、CMOS模擬多路復(fù)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.
