The defining feature of modern computers which distinguishes them from all other machines is that they can be programmed. 1_______.
In most cases, computer instructions are simple: add one number to another, move some data from one location to another, send a message to some external device, etc. 2_______. However, there are usually specialized instructions to tell the computer to jump ahead or backwards to some other place in the program and to carry on executing from there. 3_______. Furthermore, the “jump” instructions may be made to happen conditionally so that different sequences of instructions may be used depending on the result of some previous calculation or some external events. 4_______.
Варианты ответов
  • That is to say that the list of instructions (the program) can be given to the computer and it will store them and carry them out at some time in the future
  • These are called “jump” instructions (or branches)
  • These instructions are read from the computer memory and are generally carried out (executed) in the order they were given
  • Many computers directly support subroutines by providing the type of jump that “remembers” the location it jumped from

Any computer program may run from just a few instructions to many millions of instructions, as in the program for a word processor or a web browser. 1_______. Large computer programs consisting of several millions of instructions may take teams of programmers years to write, and due to the complexity of the task almost certainly contain errors. 2_______. Bugs may be benign and not affect the usefulness of the program, or have only subtle effects. 3_______. Bugs are usually not the fault of the computer. 4_______.
A typical modern computer can execute billions of instructions per second (gigahertz or GHz) and rarely makes a mistake over many years of operation
Errors in computer programs are called “bugs”
But in some cases they may cause the program to “hang” – become unresponsive to input such as the mouse clicks or keystrokes, or to completely fail or “crash”
Since computers merely execute the instructions they are given, bugs are nearly always the result of programmer’s error or an oversight made in the program design

Computer main memory comes in two principal varieties: random access memory or RAM and read-only memory or ROM. 1_______. ROM is typically used to store the computer initial start-up instructions. 2_______. In a PC, ROM contains a specialized program called BIOS that orchestrates loading the computer operating system from the hard disk driver into RAM whenever the computer is turned on or reset. In embedded computers, which frequently do not have disk drivers, all the required software may be stored in ROM. 3_______. Flash memory blurs the distinction between ROM and RAM, as it retains its data when turned off but is also rewritable. 4_______.
RAM can be read and written at anytime the CPU commands it, but ROM is pre-loaded with data and software that never changes, so the CPU can only read from it
In general, the content of RAM is erased when the power to the computer is turned off, but ROM retains its data indefinitely
Software stored in ROM is often called firmware, because it is notionally more like hardware than software
It is typically much slower than conventional ROM and RAM however, so its use is restricted to applications where high speed is unnecessary

What is the Internet? 1_______. For some, this is a favourite toy. For others – a tool for doing business. 2_______.
Through the Internet we can for a few seconds send a letter to the most distant point, while in Russia, talk to colleagues in the USA, etc. But for the most users of the Internet it is a means of entertainment.
For some people the Internet has replaced reality. At the same time one can say that the Internet is dangerous for business because the risk of losing their money is too great. Hackers can break the Internet-shops, move your money into their accounts. 3_______.
Despite this, the Network does not lose its attractiveness. People learn through the Internet news, listen to the radio, see the world through the eyes around the world of cameras, go to the library and even are taught at universities in other countries. Plans for future – to create Internet-TV. 4_______.
Each user must himself answer this question
For the third – the only way to communicate with the world
Hackers attacked and subjected ordinary users not once
Undoubtedly, the Internet is our reality and future

A general purpose computer has four main components: the arithmetic and logic units (ALU), the control unit, the memory, and the input and output devices (collectively termed I/O). These parts are interconnected by busses, often made of groups of wires.
The control unit, ALU, registers, and basic I/O (and often other hardware closely linked with these) are collectively known as a central processing unit (CPU). Early CPUs were composed of many separate components but since the mid-1970s CPUs have typically been constructed on a single integrated circuit called a microprocessor.
