tresset_1 [31]4 years ago
3 0

Explanation:

The difference between internal method call and external method call are as follows:-

Internal Method calls means when the function is called using the object of the class in the same class which is defined but where as in case of external method , it calls the function are called from other class by creating the object the respected class in other class and the function is called .

Suppose there is only one class and that class is only having all the methods and function declaration and there is no other class described . So in this case we will use the internal Method calls only .

Briefly explain what is net neutrality and why is it important today
ICE Princess25 [194]

Net neutrality also means that ISPs can't charge users access fees for particular websites. ... The goal of net neutrality is to ensure that businesses can compete freely on the internet without having to pay gatekeeper tolls. Without it consumers would look more like advertising segments than an open marketplace.

Describe 6 difference of the types of computer<br>​
Trava [24]

Answer:

<h3>1. Supercomputer</h3>

One of types of computers is supercomputer. It is a computer that is at the front-line of current processing capacity, particularly speed of calculation. It is usually used to do tasks involving intense numerical calculations such as weather forecasting, fluid dynamics, nuclear simulations, theoretical astrophysics, and complex scientific computations

<h3>2. Mainframe Computer</h3>

Another computer type is mainframe computer. It is a computer that is capable of handling and processing very large amounts of data quickly. Its calculation speed can reach millions to tens of millions instructions per second (MIPS) and it can respond to hundreds of millions of users at a time.

This computer type is mainly used in large institutions such as government, banks and large corporations.

<h3>3. Minicomputer (Mid-Range Computer)</h3>

Minicomputers are a class of multi-user computers that lie in the middle range of the computing spectrum, in between the smallest mainframe computers and the largest single-user systems (microcomputers or personal computers).

Minicomputers are usually small in scale, simple in structure, easy to maintain, and low in cost. Therefore, they are often used in universities, scientific research institutions and industrial control fields.

<h3>4. Microcomputer (Personal Computer)</h3>

The term “microcomputer” was introduced with the advent of systems based on single chip microprocessors. In the early days, the microcomputers would still have been too expensive to be owned by a single individual. But in the late 20th century, microcomputers became the most common type of computer.

Therefore, the term "microcomputer" has practically become an anachronism and has been replaced the term "personal computer (PC)".

Personal computer has developed rapidly because of its small size, convenient use, low production cost, and low price. PC computing speed can reach hundreds of thousands to millions instructions per second, which can meet the requirements of data processing and scientific computing in production, scientific research, and life.

<h3>5. Workstation Computer</h3>

A workstation computer is a high-end personal computer between microcomputers and minicomputers. It is usually equipped with large-capacity memory, external storage, and large-screen displays. Therefore, it has strong data processing capabilities and graphics processing capabilities.

Workstation computers are designed and developed mainly for professional application fields like engineering design, animation production, scientific research, software development, financial management, information services, analog simulation, etc.

<h3>6. Server Computer</h3>

A server refers to a high-performance computer that provides shared information resources and various services for many users on the network at the same time in a network environment.

A server is expected to be capable of high-speed computing, long-term reliable operation (it features error-correction of RAM; redundant cooling; self-monitoring, RAID), and powerful external data throughput.

The structure of the server is similar to that of an ordinary computer. Many smaller servers are actually personal computers that have been dedicated to provide services for other computers. But they are very different in terms of processing power, stability, reliability, security, scalability, and manageability.

According to the services provided, server computers can be subdivided into database server, file server, Web server, FTP server, etc.

Which of the following are parts of the Physical Layer?
Snowcat [4.5K]

Answer:

Physical layer is the first layer of OSI model.  The detail about physical layer and its parts is given below in explanation section.

Explanation:

The physical layer is the lowest and first layer of the Open Systems Interconnection Model (OSI). The physical layer is used for the transmission of data in bit forms. For transmission of data between devices, it uses the transmission medium that is either wired or wireless.

In the wired cable the component of the psychical layer include cable and connectors that are implemented for carrying data from one place to another or simply to transmit data between two connected devices. The wireless transmission medium is used to transmit data in the form of electromagnetic signals for carrying data into a stream of bits. Over past advancements in networking technologies, rapid growth has been seen in wireless data transmission and Wi-Fi and Bluetooth communication are few names of it.

Components/Parts of Psychical Layer

In the physical layer, the hardware components used it in are the network interface cards, connectors and interfaces, intermediate devices, modems, and cables to facilitate the transmission of data between devices or from source to destination.

  • The network interface card (NIC)

NIC is a component installed in the computer to connect it to any available devices over the network.

  • Connectors and Interfaces

Connectors and interfaces are used to connect cables that are being used for transmission of data from one source to another. The decision to choose connectors and interfaces depends on the type of cable. Typical examples are RJ-45, RJ-11, V.35, HDMI, etc.

  • Cables

Cables are the physical components of the physical layer that carry optic or electromagnetic signals for transmission of data from source to destination in the network.

  • Intermediate devices

The intermediate devices are hubs and repeaters etc. The functions of these devices are to amplify or generate the signal at the intermediate point in a network.
