A. 5 B. 6 C. 7 D. 8 Answer: C Explanation: SCSI-1 support total 7 peripherals. There are several different types of SCSI devices. The original SCSI specification is commonly referred to as SCSI-1. The newer specification, SCSI-2, offers increased speed and performance, as well as new commands. Fast SCSI increases throughput to more than 10MB per second. Fast-Wide SCSI provides a wider data path and throughput of up to 40MB per second and up to 15 devices. There there are Ultra-SCSI and Ultra-Wide-SCSI QUESTION NO: 3 You need to install a fax server.

While numerous studies have quantified biomolecular adsorption to Au NPs in terms of equilibrium binding constants, far less is known about biomolecular orientation on nanoparticle surfaces. In this study, the binding of the protein α-synuclein to citrate and (16- mercaptohexadecyl)trimethylammonium bromide (MTAB)-coated 12 nm Au NPs is examined by heteronuclear single quantum coherence NMR spectroscopy to provide site-specific measurements of protein−nanoparticle binding. Molecular dynamics simulations support the orientation assignments, which

    EECS 373: Design of Microprocessor-Based Systems Fall 2012 Lecture 3: Toolchains Instructor: Prabal Dutta Date: October 2, 2012 Note: Unless otherwise specified, these notes assume: (i) an ARM Cortex-M3 processor operating in little endian mode; (ii) the ARM EABI application binary interface; and (iii) the GNU GCC toolchain. Toolchains A complete software toolchain includes programs to convert source code into binary machine code, link together separately assembled/compiled code modules, disassemble the binaries, and convert their formats. Binary program file (.bin) Assembly Object Executable files (.s) files (.o) image file objcopy ld (linker) as objdump (assembler) Memory layout Disassembled Linker code (.lst) script (.ld) Figure 0.1: Assembler Toolchain. A typical GNU (GNU's Not Unix) assembler toolchain includes several programs that interact as shown in Figure 0.1 and perform the following functions: • as is the assembler and it converts human-readable assembly language programs into binary machine language code. It typically takes as input .s assembly files and outputs .o object files. • ld is the linker and it is used to combine multiple object files by resolving their external symbol references and relocating their data sections, and outputting a single executable file. It typically takes as input .o object files and .ld linker scripts and outputs .out executable files. • objcopy is a translation utility that copies and converts the contents of an object file from one format (e.g. .out) another (e.g. .bin). • objdump is a disassembler but it can also display various other information about object files. It is often used to disassemble binary files (e.g.
