The Computer Science Program provides students with fundamental computer science knowledge and training, and prepares them to apply their knowledge and training to produce solutions to specific problems. Students learn to define a problem clearly, determine its feasibility and choose an appropriate solution strategy. The solution strategy will study, specify, design, implement, test, modify, and document the solution. As part of the solution strategy, students will learn to evaluate alternative designs, perform risk analysis on alternative designs, and finally, communicate solutions to colleagues and other professionals. A key element to all of this is the ability of the student to work and collaborate within a team environment throughout the entire problem-solving process.
The Computer Science Curriculum has a set of core courses designed to accomplish two primary objectives:
- provide practical knowledge that will be of immediate use in the profession; and
- provide a solid foundation in theoretical computer science, so that graduates will have the fundamentals necessary to acquire knowledge in a rapidly evolving discipline.
We are dedicated to preparing students to be the next generation of scientists and professionals who will be able to compete effectively in the changing global society.
Areas of Learning Focus: Software Engineering, Cybersecurity, Artificial Intelligence, Data Science, Game/Robotics, Cloud Computing.

Try blocking: advertising satellites will light banners in the sky
Researchers from Skoltech and MIPT have studied the potential payback of space missions to display advertising images by groups of small satellites called cubesats.
If such satellites are equipped with reflective screens and placed in specially selected close orbits, a group of cubesats will be visible from Earth as a bright constellation in the form of an image ordered by the advertiser. The model takes into account the choice of optimal orbits, satellite fuel consumption, population of target cities, outdoor advertising prices, and much more. The budget of the advertising mission considered as an example is estimated at tens of millions of dollars, and according to calculations, it can turn out to be a plus. An article with the results of the study was published in the journal Aerospace .

“We have been researching the technical aspects of space advertising for years,” commented its first author, Shamil Biktimirov, an intern researcher at the Center for System Design at Skoltech.
— This time we considered the economic side of the issue. Surprisingly, our analysis shows that launching a promotional mission of fifty small satellites can indeed be economically justified. The main importance in this case is the duration of the stay of a group of satellites in orbit and the size of the territory from which the displayed images are visible.”
In previously published works, the team presented the concept of an advertising space mission using cubesats, considered the optimal orbits for their group flight and the mechanisms for restructuring in the group when images change. The new paper builds a complex model that links the displayed images, the most suitable orbits for them, the size of the sunlight reflectors and the expected number of views of the images by residents of large cities. This model allows you to calculate and optimize the profitability of the mission.
“To analyze the economic feasibility, we have developed a price map that matches each city that falls within the formation’s coverage area with the potential revenue from displaying advertising.
Revenue forecasts are based on statistical data on the cost of outdoor advertising in the city, the size of the population and factors that limit the potential audience: cloudy weather, cold weather that does not encourage walks, the distribution of city residents by age groups,” Biktimirov added.
The impression counting model works like this: the most advantageous city for display in the field of view of satellites is selected, the image is displayed in it for one minute, then the next city. Revenue was projected for missions with satellite launches in different months, as the cost of displaying ads varies throughout the year. It turned out that space advertising is most profitable in winter. Numerical simulations show that a space advertising mission can generate $2 million in revenue per day, which translates into a payback period of one month. At the same time, a group of satellites can remain operational for up to several months (although image restructuring reduces this period), which indicates the possibility of getting into plus.
In the article, the researchers note that the typical fears associated with the risk of light pollution, in reality, are unlikely to be justified using the proposed approach. The fact is that the satellites themselves must be illuminated by sunlight, and from the Earth they can be visible after sunset for the observer. As a result, the display of advertising at night is excluded: the image will light up shortly before sunrise or shortly after sunset. In addition, economic considerations make the technology applicable primarily in large cities, where in any case there is a constant illumination of the sky from the ground.
“We have long been engaged in control algorithms in groups of spacecraft, and we usually solved problems related, for example, to distributed measurements of the geomagnetic field or registration of cosmic gamma-ray bursts, which also require building a group in a certain order. In this project, we decided to move away from standard productions and work with an advertising mission project, which unexpectedly turned into a rather beautiful task.
As it grew, our previous experience in modeling communication constellations also came in handy, since the “visibility of the image from the Earth” model and population density models for service estimation are built on similar principles. It so happened that our estimates show the possibility of a payback for the project, and we are familiar with at least two startups that were thinking about implementing a trial mission. For us, this research is rather a way to work out our techniques for controlling groups of spacecraft, which, I am sure, will be useful to us more than once in future projects,” said Dmitry Pritykin, Associate Professor of the Department of Theoretical Mechanics at MIPT.

What is a local network? How to create and configure a local network
Due to the fact that the number of Internet users is constantly growing, and the development of computer and information technologies is accelerating, it became necessary to solve a huge amount of tasks that are associated with receiving and transmitting data.
That is why there was a need to create local area networks. After all, LAN is the technology of the future, which is available today.
Local area network — these are systems that include various elements integrated with each other:
- Structured Cabling System (SCS)
- Servers
- Network devices (switches, repeaters, gateways, access points)
- Workstations (end user computers)
- Office equipment (Printers, scanners, MFPs)
And may include:
- Communication channels
- VPN
- Miscellaneous media equipment (video conferencing, projectors, televisions and panels)
At the same time, they can be located not only in the same room, but also at a considerable distance from each other. Networks can be wired or implemented wirelessly. They are designed to combine computer equipment into one network used for data transmission.
Basic properties of local area networks
LANs are characterized by scalability, flexibility, resiliency, reliability, security, and manageability.
These same properties are the main characteristics of the LAN.
The first property is necessary for the possibility of increasing the expansion of the network, without its cardinal restructuring (with minimal architectural costs).
Flexibility allows you to quickly respond to new technologies and adapt to different types of cable connections or wireless network options.
Fault tolerance indicates the stability of the LAN in the event of failure of its individual nodes. To do this, local area network systems must have redundant lines, spare nodes that can be used if the main networks fail.
Reliability indicates that the LAN will last as long as possible even when the needs of the company increase, the load increases, and downtime can be too expensive for the organization.
A very important property is protection, which makes it possible to ensure the security of the network from any unauthorized access and external attacks.
Manageability implies that local networks should have good monitoring tools that help to quickly identify various interference and malfunctions.
Thanks to this, downtime and various unforeseen moments that affect the efficiency of the company are almost completely eliminated.
The main tasks of local area networks are to implement shared access for each user to various data, programs and devices. Thanks to this, users will be provided with simultaneous access to the necessary operations. In addition, local lines will allow you to process and store data, transfer the results of information to clients, monitor the implementation of projects, and many other functionalities.
The main components of a local area network
A local area network cannot fully operate without special equipment. The main components of such a network can be called passive equipment (patch panels, wiring cabinets, sockets, cables and cable channels), active equipment, which is routers, switches, all kinds of media converters. Also, these are peripheral devices (printers, servers, scanners) and computers, laptops, tablets and mobile devices.
Benefits of using a local area network
A local area network allows you to solve many different problems in a company. There are several main advantages to using a LAN. First of all, this is the fact that this type of system allows you to store various data on a file server. Thanks to this, it is possible to simultaneously work with many clients, update data in various network programs, and use information that is protected in files and directories. Also, the local network allows you to exchange information between all computers connected to it. Each user has access to the global network if there is a special switching node. Among other advantages, it is worth highlighting the full printing of data by any user on shared printers.
Requirements for local area networks
Today, local area networks can differ in topology, size, operation algorithms, depending on the needs and structure of the organization. They can be operated in a wide variety of countries, but at the same time, similar requirements may be imposed on them.
First of all, it is reliability, which should ensure the functioning of the network even if several nodes fail. The second important requirement is the speed provided by high-speed channels for data transmission. Another important requirement is adaptability to expand networks by placing computers where needed and expanding the functionality of the LAN.
The simplest network consists of at least two computers connected by a cable. This makes it possible to share data. Today, the local network and the Internet allow you to create very complex systems, so there are certain nuances of designing local networks. For these purposes, in most cases, special software products are required. Such products have a wide range of tools, a user-friendly interface, provide the ability to install additional applications and extensions integrated with them, show the location of various nodes and system elements. It can also be completely different functions that are necessary to build an effective working local area network.
Local area network: design and network equipment
Various equipment is used to build a local area network. The most commonly used of such equipment is a hub (hub), switch, repeaters, routers and modems or other signal conversion devices.
Local computer networks — what is it?
From the above information, it can be understood that such networks are a closed space in which not only computers are connected, but also a variety of equipment for printing, scanning, transmitting and storing data. At the same time, you need to understand that there are various topologies of local networks: a common bus, a ring, as well as a star and other options.
The first option resembles a central line where the server and individual workstations are connected. This topology was popular before when cabling requirements were not so great. The advantages of this option include low cable costs and the ability to turn off individual computers without loss for the entire network.
The second option assumes that the server and all workstations are connected and connected to each other by a ring. Information is also transmitted around the ring, but it only arrives at the addressee when the network recognizes that the computer data and information match. The advantage of this type lies in the ability of workstations to transfer data between themselves even without a server.
In a star topology, each computer is connected to a central station (network core), while the file server and the main server and network services are located as close as possible to this core. Among the advantages of such a topology is the stable operation of the entire network even if the cable of one computer is damaged. Also, a connection is simply made here, there are mechanisms for protection against unauthorized interference, and the data transfer rate is quite high.
What is a local network is already clear, but it must be understood that a wired network (SCN) is often integrated with a wireless local area network, since recently it has been used much more often due to its maximum ease of use and its versatility.
Stages of building computer networks
Building computer networks includes such steps as development, design, installation, testing and maintenance. First, a pre-project survey takes place, then the requirements for the LAN are formed, after which the direct working design of the network is carried out. The next stage is the preparatory work, during which holes are made for the installation of equipment, a place is allocated for its placement, the cable system is crossed and installed. Then passive and active network equipment is installed, networks are tested, sockets are labeled, and a journal is compiled to account for communication lines. At the final stage, start-up and adjustment works are carried out.
What is a LAN, its capabilities — this is already clear, but not everyone can know what a wireless LAN is: Windows 10, an algorithm for setting up such a network. Usually such a network is created quite simply. You need a router with a Wi-Fi module that enables this interface.
