Week 3: The Central Processing Unit and RAM



Since the week's topic is central processing unit (CPU), I wanted to share what I learned about CPUs, their function, and their relationship with random access memory (RAM). 

CPUs are the heart of the computer; they might be tiny, but they are powerful. Some common components CPUS comprises are a register, a special wire call clock, and a quartz oscillator. 

Registers are tiny storage areas on microscopic semiconductor circuits holding charges on the CPU. It is a worktable for the CPU, and a special wire called a clock (CLK) lets the CPU perform a command. A quartz oscillator is a system crystal that determines the speed at which a CPU and the rest of the PC operate. 

The CPU connects with the RAM through the external data bus (EDB), so they can talk. However, since RAM is a data set, there is a middleman between CPU and RAM that handles data transfer between CPU and RAM; the middleman is called the memory controller chip (MCC). 

Although modern CUPs are more complex, with multiple cores and threads, and efficient in handling the overall process, the gist is the same. The CPU goes through multiple pipeline stages like fetch, decode, execute, write, etc. 

The computing world has come a long way since the early days; as we speak, the two major CPU manufacturers, Intel and AMD, compete with each other. produce better, faster, and more efficient chipsgen of computers.

Week1: Introduction and Cloud Computing

Image
Hello everyone, my name is Santosh Pradhan, and I am currently pursuing an undergraduate degree in information technology at Bellevue University. Prior to pursuing my degree, I had no prior experience, except for the basic troubleshooting that everyone learns. So far, I have learned a great deal about networking, basic information technology, and some cybersecurity concepts. Although most of the courses have covered virtualization and cloud computing to some extent, none of them have provided full details. I am excited to learn about cloud computing and its governance.  As the semester progresses, I will update the blog on a weekly basis and share my experiences with you.

Week 12: Tools for Monitoring Network and Blog Wrap-up

There are various tools to monitor a network; monitoring a network can help detect issues, be aware of the problems, or make sure the network does not have any anomaly in the network. Here are some of the tools that can help to monitor the network: ·        Packet Sniffers – a software tool that tracks and collects internet packets. The packets that are collected will be stored in a file called a capture file.  Usually, the packet sniffer software also comes with a packet analyzer to analyze the packets that were captured. ·        Protocol Analyzer – this is a program that analyzes the packets that packet sniffers capture. A good program can let the network administrator filter information based on their needs. One of the well-known software is Wireshark. ·         Packet Flow Monitoring – this tool tracks traffic and packet flow between devices. This helps to track the volume and ...

Week 3: Migration to the Cloud

Image
  This week, we learned about the various decision-making processes involved in migrating to the cloud. The book talks about five major phases of the migration process: Assess, Plan, Migrate, Validate, and Manage . While assessing and before initiating the migration process, it is essential to establish a baseline of the network, operating system, and other key performance indicators. It is essential to minimize the impact of downtime and maximize network bandwidth availability during the migration. After the planning process is done, there are various ways to execute it; the common migration processes are P2V, V2V, V2P & P2P. Amazon also provides a migration truck to make the process. The book also discusses deploying the migration and validating it to ensure that it is working through various types of testing, including functional testing, performance testing, load testing, and others.
