Also the workers notice the inconvenience while managing large workloads. What may be causing these problems? What decision should the company make? |
The company wants to execute a lot of things at the same time, which is now impossible, so each worker needs to use different languages to get the job done. In their case the company should use Operating System |
Workers cannot send direct instructions to the complier to execute various activities since it is extremely difficult for the user to transform their request or instruction into one language. In their case the company should use Input/Output System |
The company uses a system that dedicates time to a certain activity and frequently switches between the computers, which is overloading while completing long tasks. In their case the company should use Batch System |

247. Data access can be difficult due to many problems. Which of the following situations describes the documentation problem? |
I need your information now or I won’t be able to use it. The data transfer process is too slow, possibly unavailable. Because you have an older system, the migration process is too slow and inefficient. I must have immediate access to your data; otherwise your data will not help me |
The systems are not connected to the same network. Your data is too inconvenient to download. When the systems are not on the same network, downloading data can be too inconvenient. The widespread use of the World Wide Web has reduced the number of problems in this area, but separate networks will always exist |

This was made possible by the creation of 4-bit processor |
This was made possible by the creation of UNIVAC |
249. Martin Timmerman formulated the necessary requirements for an RTOS. Two of them are about priorities. Why the combination of priorities is necessary? |
The RTS software is a fixed set of pre-developed modules, and the choice of a program for execution is carried out by interrupts (based on the current state of the object) or in accordance with the scheduled work schedule |
It is the opposite of “necessary”, as the combination of thread priorities can lead to problems such as priority inversion and deadlock |
RTOS needs to share resources. There are a lot of real-time process and system resources for their operation must be available in advance |
250. Most businesses don’t want to deal with non-core tasks, which include the IT infrastructure. And if it has to pay for a data center, it has to function at maximum efficiency.

It is impossible to abandon IT altogether – it is equal to giving up doing business, but phased financing and speed of commissioning come to the fore. What do today’s IT managers face while having limited budgetary resources to expand data centers? |
Task of providing more services to more users, meeting ever-increasing performance expectations, storing and managing exponentially increasing amounts of data, better protecting the network, and ensuring system stability |
Mail to be lost when using postal mail, and neither the sender nor the receiver would know where the letter was or whether it had been delivered |

251. Prior to the transistor’s discovery in 1947, the only way to execute amplification of a weak current in an electronic circuit was to use a vacuum tube. What were the initial advantages transistors demonstrated over small vacuum tubes? |
Transistors had longer lifespan, were smaller and many of them could be placed on a single chip |
Transistors were larger, while consuming far less power. They were more reliable |
Small vacuum tubes’ production cost was much higher. Tubes’ material turned out to be harmful for people’s skin |
