difference between computer science and software engineering

difference between computer science and software engineering

First, it is good to understand how these two disciplines are similar. After all, they both care about computer software and almost everything. For example, people with IT or programming education may specialize in programming, system software, software architecture or programming. These two disciplines overlap because they both require close computer literacy, especially computer software and its various applications.

Of course, there are differences between these two paths, although no computer scientist explains this difference in the same way. One way to understand the difference is to look at two specific words in a given naming system; ie "engineer" and "science" (or "scientist"). Engineers are inherently tasked with developing solutions to problems or creating more efficient processes using existing tools. As an extension, software engineers often create new software using already-used languages ​​or known practices. In contrast, scientists often deepen their knowledge in the field of research and development (and development) of their field. In this way, IT professionals can help create new algorithms or types of languages ​​that will eventually be used to create software.

Many agree that the computer science degree better prepares students for abstract problem solving and research into the development of computer technology, while software engineering degrees provide students with an understanding of the software development process and its applications. as an engineer. Nevertheless, the two disciplines are really a circle located on the Venn diagram, where each really focuses on different areas of software development (one is practical, the other is theoretical) and has a common emphasis on acquiring in-depth knowledge of computers and code.

wi fi technology

wi fi technology:

Wireless Wi Fi represents wireless Fidelity. WiFi It is based on the IEEE 802.11 technology suite and is a network-based (LAN) platform designed to provide increased coverage.

Today’s wireless system supports a maximum data rate of up to 54 Mbps and provides indoor conditions of more than 30 meters away.

WiFi has become the ultimate mobile device in the ultimate broadcast environment in homes, offices and public places. These procedures are only approx. They offer a distance of 1000 feet from the access point.

WiFi offers higher and more expensive data speeds than 3G systems, especially when working with a large 20 MHz bandwidth, but the WiFiWiFi system was not designed to support a pandemic.

One of the biggest advantages of WiFi over WiMAX and 3G is the full range of wireless devices. Most laptops introduced today have an integrated WiFi port. Air traffic controllers are integrated with a variety of devices, including personal information assistants (PDAs), cordless phones, cell phones, cameras, and media.

WiFi is half duplex:

Every WiFi network is a controversial TDD system where all access points and telephone exchanges search for the same channel. Thanks to shared media services, all WiFi networks are twofold.

There are hardware manufacturers that sell WiFi settings, but the implementation of this technology does not include a certain set of standards.

wireless networking

what is wireless networking?

A wireless network (WLAN) performs the same function as a wireless network - to connect to a computer. Since "wireless" does not require an expensive cable, the advantage is that it is usually easier, faster and cheaper to install.

On the other hand, it is difficult to create a network by using wires on walls and ceilings and therefore expensive. But even if you already have a wired network, wireless networks can be an expensive way to expand or expand. Of course, there is no such thing as an air network, since most people will use wires at the same time.

Basics:

Wind turbines use radio frequency (RF) technology, which is the frequency of electrical energy associated with the transmission of radio waves. When an antenna provides current RF, an electric field is created that can be propagated through space.

The cornerstone of a wireless network is a device called an access point (AP). The main function of the access point is to send a wireless cable that the computer can detect and "configure." Because wireless networks are connected to a network, Internet sites can often be used as a reference for network resources, such as Internet connections.

To connect to and from a network, a computer must have a wireless network card. They are built into your computer, but if not, almost any computer or laptop can support wireless technology with optional slots, optional plugs connected to the port USB, or PC Card slot for laptops.

There are three types of wireless networks - WAN, LAN and PAN:

Wide Wireless Area Network (WWAN): WWAN was developed using a telephone line that is usually provided and maintained by mobile service providers. WWANs can provide a way to connect, even if they are not otherwise contagious.

Wireless Local Area Network (WLAN): A wireless local area network is a wireless network that transmits radio. The background path is usually equipped with a cable as well as one or more valves that connect wireless providers to the network. The size of the WLAN can vary from room to room in a small yard.

Wireless Personal Area  network (WPAN): WPAN is a short-range network that uses Bluetooth technology. It is commonly used to connect compatible devices near a central location, such as a work area. WPAN is approx. 30 fet.

how does wireless technology work

how does wireless technology work:

Wireless networks or WLANs act as a wireless device - to connect a computer.

Wireless or WLAN serves the same purpose as a wired device - to connect to a computer. Since wireless does not require expensive cable, the advantage is that it is usually easier, faster and cheaper to install.

On the contrary, it is a difficult task and therefore expensive to create a network by using wires on walls and ceilings. But even if a network were already in place, wireless networks could not be an economic means to expand or expand. Of course, there is no wireless network because most people will reconnect to the network in time.

Basics:

Wireless systems use radio frequency (RF) technology, which measures the frequency at which the electrons of a radio wave propagate. When the RF current is transmitted to the antenna, an electric field is generated that can propagate across the field.

The backbone of a wireless network is a device called an optical array (AP). The main function of the access point is to transfer the wireless signal to a computer that can detect and "configure." Because wireless networks are connected to wired devices, access points are often used as a connection to wired equipment, such as to connect to the Internet.

To connect to an access point and a wireless network, a computer must have a wireless card to carry it. It is connected to the computer, but if you do not have one, you can connect any computer or laptop to a portable slot, USB port, or, on a laptop, those who prefer a connection connected to PC and card slot.

Wireless speed and range:

When you purchase wireless network hardware, it indicates a number of features (ie data transfer) and is based on the standards of the wireless standard used, with technical improvements. Honestly, these results are always optimistic.

Although the internet speeds of 802.11b, 802.11g and 802.11n are 11, 54 and 270 megabits / s (Mbps), these figures show a positive development as they are not available. In general, you should expect to receive only one-third of the media performance.

It is also important to keep in mind that wireless networking informs and defines distributed networks, which means that other computers you are connected to wireless technology will reduce the amount of data you send and receive. Just as air conditioning can be very diverse, so can the environment. For example, the 802.11b g steering wheel works slightly, reaching 100 meters indoors or 1,312 meters high, but the key is to "reach". You probably will not see anything for these numbers.

As you can expect, the closer you get to where you are going, the stronger the signal and the faster the connection. The quantity and speed achieved by transport and air conditioning depend on the operating environment. This leads to intervention.
