Programming in Scratch

Prior to attempting to create a program in Scratch I had a limited amount of experience in programming. I have done some minor programming with Python in the past, but not enough to fully understand it or run lines of code on my own. Initially I was having an issue with getting the characters in the program to do what I fully wanted them to do. The easiest way I have found to overcome this issue was to start small with some of the commands like getting the characters to move from one point to another. I started off with the basic motions and then decided to add more of the details after the main components were in place.

When I first read over the assignment, I thought it was going to be easier than it was. I feel as though this program is a great way to learn how the complexities of programming work on a much simpler scale. When I was browsing around the website, I noticed that other people have created some intricate and complex games. I’m sure if I took the time to understand the program a little bit better, I can create some more interesting and engaging programs. The programming languages used in the Scratch are one of the simplest forms compared to the languages outlined in the textbook. I found it to be much easier to create the program in Scratch than it was to complete some of the activities in the textbook. I feel as though Python is one of the most common programming languages available. I have noticed that while teaching myself ethical hacking that a lot of the scripts I was running were Python based. Although, I am still on the fence about what language I want to stick with learning.

Peering Points and the Network Application Interface

According to Gibb (2019), “Peering is a method that allows two networks to connect and exchange traffic directly without having to pay a third party to carry traffic across the Internet.” Utilizing a peering point allows users to send a receive data directly to one another without the need to route through other computer networks. Doing so allows for a quicker, more efficient, and safer form of communication. Researching the total number of active Internet Exchange Points (IXP) proved difficult as it was hard to pinpoint an accurate number. However, according to Rosas (2021), “as of January 2021, of the 630 registered IXPs, 229 are in Europe, 126 in North America, 140 in Asia-Pacific, 96 in Latin America and the Caribbean (LAC), and 39 in Africa.” These numbers are constantly changing as new IXPs are added, and some are removed. Finding a definitive number of Internet Service Providers (ISP) globally was also difficult to accomplish. Most sources seem to point to the Nations Encyclop

VLAN Aggregation for Efficient IP Address Allocation

The project I chose to summarize on the Internet Engineering Task Force (IETF) website was RFC: 3069, VLAN Aggregation for Efficient IP Address Allocation. Within this project, the authors point out how inefficiently a Virtual Local Area Network (VLAN) allocates IP addresses along with their proposed solutions. I have also attached a diagram showing how the network would look pertaining to this project. Currently, an IP subnet would be made for each existing customer by understanding how many hosts they currently need and may need in the future. Based on that total number, the IP subnet and gateway address would change according to how many hosts the customer requested. For example, if a customer has indicated that they need ten hosts, and they only use five, the additional five that are not in use cannot be used by another customer. An illustration of this is shown below. The proposed solution to this problem is to allocate IP addresses under the same IP subnet and gateway address uti

Access Lists and Capabilities

To implement an access matrix, we must first understand what it is. An access matrix is a protection model within an operating system consisting of objects and domains. The access matrix determines which processes interact with objects within the domain. Objects within the domain can consist of both hardware and software. The lists below show the advantages and disadvantages of access lists associated with objects, and capabilities with domains. Access lists associated with objects Advantages Corresponds directly to the user’s needs. Easy revocation and review of access. Disadvantages Difficult to determine access rights for a domain. Takes time to search the domain for access rights. Capabilities with domains Advantages Useful for localizing information for a process. Secured against unauthorized access. Disadvantages Inefficient at the revocation of capabilities. Does not correspond directly to the user’s needs. Even though each implementation has its own strengths and w
