IMAT5122 Computer Systems and Network Assessment Answer

IMAT5122 Computer Systems and Networks

IMAT5122 is a post-graduation course that is taught at De Montfort University. This summative unit revolves around the awareness of the current problems which are faced in computer systems and networks. This course is much helpful in evaluating current computer systems and networking technologies. Key benefits of using a large cache for maintaining cost-effectiveness and improving performance are the key lessons that can be learned from this course.

This course is also helpful for the students to learn about the different types of computer interfaces for connecting the secondary storage devices. Benefits and limitation of open-source licensed software, the concepts of running multiple processes and threads in parallel, the difference between paging and segmentation, description of each layer of the OSI model, usage of computer networks using protocols, and common network security features are the other major lessons which is taught in this course.

Brief of ENGT5115 Assessment

There are numerous topics that were covered in this course such as checking disk usage folder wise. The course discusses that the conventions of Linux are very much different from Windows, df and du are the two commands which are used in a Linux-based system for checking disk space. Du runs without any option, whereas df has few options, on the other hand, the du command has numerous parameters which can be used for getting the results in any format.

The course highlights the current problems which are faced in computer systems and networks such as security leaks, no data backups, use of outdated software, connectivity concerns, and lack of Information Technology support required to address the regular concerns of a network. Apart from these challenges, there are other challenges that are associated to computer networks as performance degradation, host identification, configuration conflicts, capacity concern, monitoring the performance of a network is the other challenge associated with computer systems.

There are different categories of computer systems which are used both in our society as well as in contemporary business environments such as mainframe computers, super computer, tablets, smartphones, laptops, Personal computers and a Work station computer. There are diverse categories of networking technologies as well such as Personal Area Network (PAN), Local Area Network (LAN), Wireless Local Area Network (WLAN), Campus Area Network (CAN), Metropolitan Area Network (MAN), Wide Area Network (WAN), Storage Area Network (SAN), Passive Optical Local Area Network (POLAN), Virtual Private Network (VPN) and Enterprise Area Network (EAN).

 IMAT5122 course also highlights the key benefits of using large cache for maintaining cost effectiveness and improve performance different types of computer interfaces for connecting the secondary storage devices as it helps in storing and working with the instructions which are recently used in the system.

The problem coming from slow data retrieval from the main memory can be addressed with the introduction of bigger cache. Bigger cache allows CPU to run programs faster compared to the previous occasions. Chances of cache miss can also get reduced with the presence of lots of cache. Thus, bigger cache can help in improving the performance of a computer system.

There are benefits and limitations of open-source licensed software which are taught in this course code. The disadvantages of open-source software are difficulty to use, compatibility issues, absence of a licensed agreement which lead to warranty issues, and the presence of different types of hidden cost associated to the software. The presence of the malicious users associated to this software and lack of support from any customer service unit are the major limitations of an open-source licensed software.

On the other hand, there are few advantages of open-source licensed software as well such as no hardware cost required to install the software, consolidating, available in unlimited quantities, easy to debug and audit, can be automatically updated, vendor integration not required and a collaborative environment can be created using this software. The course also helps in understanding that two threads can run at a time in a CPU.

Difference between paging and segmentation is that paging is method which can be used for dividing programs into pages of fixed size, on the other hand, segmentation helps in dividing the program into different sizes. Operating system is used in paging, however only compile is used for segmentation. In segmentation, section size is determined by the users, however in paging page size is determined using a hardware. Paging is a faster process as compared to segmentation. At the same time, it can be said that paging can lead to internal fragmentation and segmentation can lead to external fragmentation.

Description of each layer of the OSI model was the other lesson which is taught in this course code as well. Physical layer helps in the transmission of raw unstructured data bits from this layer to the physical device. Data link layer is helpful in making the connected nodes perform node to node data transfer where data is packaged into frames.

Network layer is used for receiving frames from the data link layer to the networking devices. Transport layer is used for managing the delivery as well as the error checking approach of the data packets.

Session layer is helpful for maintaining conversion between different computers connected to a network. Presentation layer helps in the translation of data for the application layer based on the syntax which is accepted by the system. The application layer is helpful in the interaction procedure between the users and the software application.

There are different categories of protocols that are usually used such as Transmission Control Protocol (TCP), User Datagram Protocol (UDP), File Transfer Protocol (FTP), and HyperText Transfer Protocol (HTTP). The most common network security features are anti-malware software, intrusion detection system, firewalls, and email security.

Hence, this course is helpful for students to understand insights of computer systems and networks.
