What is Computer Bus: The electrically conducting path along which data is transmitted inside any digital electronic device.

What is Operating System? Types of OS, Features and Examples

A computer is a machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks. A "complete" computer including the hardware , the operating system main software , and peripheral equipment required and used for "full" operation can be referred to as a computer system. This term may as well be used for a group of computers that are connected and work together, in particular a computer network or computer cluster.

Supercomputers are the fastest and the most expensive computers. These huge computers are used to solve very complex science and engineering problems. Supercomputers get their processing power by taking advantage of parallel processing ; they use lots of CPUs at the same time on one problem. A typical supercomputer can do up to ten trillion individual calculations every second. Example Supercomputers:. Mainframe colloquially, "big iron" computers are similar to supercomputers in many aspects, the main difference between them is the fact that a supercomputer uses all its raw power to focus on very few tasks, while a mainframe perform thousands or millions of operations concurrently.

Primary Memory This is the main memory of the computer. This type of RAM is a volatile memory that needs to be refreshed with voltage regularly. Each of those act as the working storage of every computer, with DRAM serving as the main memory and SRAM being used for high-speed caches and buffers. Semiconductor memory is used in all forms of computer applications: there are many types and technologies that are used. Primary memory is further divided in two types: 1. ROM Read Only Memory We will try and cover every topic one by one so that you can have enough material with you before the main exam. Personal computers: - This is the most common type found in homes, schools, Business offices etc.

Computers differ based on their data processing abilities. They are classified according to purpose, data handling and functionality. According to purpose, computers are either general purpose or specific purpose. General purpose computers are designed to perform a range of tasks. They have the ability to store numerous programs, but lack in speed and efficiency.

What is BUS? | Types of Computer Bus

An Operating System OS is a software that acts as an interface between computer hardware components and the user. Every computer system must have at least one operating system to run other programs. The OS helps you to communicate with the computer without knowing how to speak the computer's language. It is not possible for the user to use any computer or mobile device without having an operating system. To speed the same process, a job with a similar type of needs are batched together and run as a group.

On the basis of data handling capabilities , the computer is of three types:. Analogue computers are designed to process analogue data. Analogue data is continuous data that changes continuously and cannot have discrete values. We can say that analogue computers are used where we don't need exact values always such as speed, temperature, pressure and current. Analogue computers directly accept the data from the measuring device without first converting it into numbers and codes.

A computer is one type of machine manage different kinds of programs to perform useful tasks to the users. Computer gives proper response to the users through the set of instructions arranged in proper order. It has storage capacity along with execution benefits. Computers can perform both complex and simple operations. Based on types of actions, computers design in several formats with hardware and software specifications.

Росио покачала головой: - Это. Но вам ее не найти. Севилья - город большой и очень обманчивый.

Клушар едва заметно кивнул: - Просто… я переволновался, наверное.  - И замолчал. - Подумайте, мистер Клушар, - тихо, но настойчиво сказал Беккер.

Беккер знал лишь, что немец был с рыжеволосой спутницей, а в Испании это само по себе большая редкость. Клушар вспомнил, что ее звали Капля Росы. Беккер скорчил гримасу: что это за имя.

Беккер беззвучно выругался. Уже два часа утра. - Pi'dame uno.

 Хорошо, это ничего не дает. Начнем вычитание. Я беру на себя верхнюю четверть пунктов, вы, Сьюзан, среднюю. Остальные - все, что внизу. Мы ищем различие, выражаемое простым числом.

Дэвид Беккер стоял в центре пустого зала и думал, что делать. Весь вечер оказался сплошной комедией ошибок. В его ушах звучали слова Стратмора: Не звони, пока не добудешь кольцо. Внезапно он почувствовал страшный упадок сил. Если Меган продала кольцо и улетела, нет никакой возможности узнать, где оно .

На экране ВР у входа толпились и множились хакеры, число их за последние минуты удвоилось. Теперь оно начало расти в геометрической прогрессии. Хакеры подобны гиенам: это одна большая семья, радостно возвещающая о любой возможности поживиться. Лиланд Фонтейн решил, что с него довольно этого зрелища. - Выключите, - приказал .

    A computer is an electronic device, operating under the control of instructions stored in its own memory that can accept data (input), process the data according to specified rules, produce information (output), and store the information for future use1.
