They are more powerful and reliable and, importantly, are very economical in terms of energy consumption. Their1 / 30presence opens a new era in the field of IT technologies and means that the cloud technology is getting closer.LDAYtRyKfEThese processors are primarily designed for servers, data centers (DPC) and supercomputers. The emergence of this class of devices is not accidental. According to the regional director of Intel in Russia and other CIS states Dmitri Konash who spoke at the event, the market of IT-technology is developing so rapidly that, according to forecasts, by 2015 there will be 15 billion devices connected to the Internet, and over 3 billion of active users.Zzz6ZB2Ltk 上周，英特尔公司向俄罗斯和其它独联体国家的公众推出了英特尔Xeon E5-2600 系列处理器，它们更加强大可靠，尤其是在能量消耗方面更加经济实惠。

The repetition of clock pulse can vary from very low rate to very high rate.T9. A synchronous device changes its state only on the arrival of a clock pulse.F10. A clock input may occur at any time.T11. The clock pulses are used to synchronize all operations of the shift register.T13. A unidirectional shift register is capable of shifting in one direction only.F14. In a shift-left register the serial input determines what goes into the leftmost position during the shift register.F15. To provide parallel transfer capability some additional input and output lines should be provided to the shift register.Choose the best answer for each of the following1.

A 6 bit alphanumeric code can represent 128 different characters.F 22. Eight bit codes are limited to representing 128 different characters.T23. An extra check (or parity ) bit is often added to each 6, 7, or 8 bit character represented in storage so that it will be possible to detect coding errors that may occur.T24. If a computer uses an odd parity format to detect errors in character codes, thenevery valid character code will always have an odd number of 1 bits.T25. Processor comes with a unique set of operations called an instruction set.F 26. In an instruction, operands specify the function to be performed.T 27. A processor's job is to retrieve instruction from memory and perform step bystep operations,3.3 True or FalseF1 All operating systems on various computers take the same size.F 2 All operating systems were written in a low level language.T3 The user can't use the computers at all if there is no operating system on the computers.F4 The operating system exists in the lowest layer of a computer.T5 The system calls are provided by the operating system.T 6 A computer's operational software defines the schedule of jobs awaiting execution.F7 Though an operating system can schedule the execution of jobs, it does not manage the availability of I/O devices.精品文档．精品文档T 8 The IOCS component of an operating system controls I/O operations.T9 It is a major problem for the operating system to map the logical file concept onto physical storage devices such as magnetic tape or disk.F10 Files can only be direct access on a disk system.T 11 The logic structure and nomenclature of the different operating systems vary considerable.F12 The form of the system prompt is the same for every kind of operating system 13 You must boot the system, before you use a microcomputer.T14 Spooling is an

must be converted by a compiler to be used by the computer.F6 High-level languages require that programmers work with individual main storage locations.. 5T7 A compiler is translating program that converts high-level languages into machine language.T9 A flowchart loop indicates the repetitive performance of steeps to process data.T10 None of the computers consists of hardware only.F11 Programs written in high-level language can be executed by the computers without the help of a translator program~T13 Each symbolic instruction has one-to-one correspondence with the machine instruction.T 14 Writing a program in a high-level language need not take account of the hardwareof the computer.T 15 The opode of an assembly language instruction specifies the operation that is to beperformed by the microprocessor.T 17 The mnemonic for the instruction is the symbolic representation of the actual binary code that the computer directly executes.T 18 A label is on the left of the assembly language statement.精品文档．精品文档T 21 To enable the computer to solve an application problem programmers have to write programs in order to translate the application concepts into computerconcepts.T 22 A class is

object-oriented programming when in its early days.F24 Object-oriented programming languages are absolutely different from the LISP programming language.T 25 A program may produce incorrect output even if it runs OK.T 26 An error will occur if a program wants to use a deleted file.F 27 All the errors can be avoided.T 28 A warning will not terminate the program.T 29 Although we could not avoid all the runtime errors, we must take appropriate action when it happens.Match the following terms to the appropriate definition1 program2 programmer3 machine language4 assembler5 source6 object7
