Grandpa was always on the move, and once he decided to go, he didn't waste time looking back. He was only four when his mother died, and as soon as he was old enough, he left Irwin, Missouri, and traveled the world before settling in Kansas City in the early 1920s.

"Okay, good night, God bless you, see you tomorrow, Della Kay." Curiosity got the best of him, and he decided to pay her a surprise visit.

For 60 years.

I'm the firstborn child of that marriage.

Because we were always together, I was quickly dubbed his "little buddy." My sister arrived five years after I did, and things seemed to fit perfectly when she and my grandmother bonded in much the same way.

My sister and I tried to fill the void in their lives and became even richer for it.

Understanding Tense Changes in Reported Speech

When converting direct speech to reported (or indirect) speech, verb tenses often shift backward. This process is known as "backshift." Below are common tense transformations:

1. Processes

A process is a program in execution. It is a unit of work within the system. A program is a passive entity, while a process is an active one. A process needs resources to accomplish its task (CPU, memory, I/O, files). Process termination requires the reclamation of any reusable resources. A single-threaded process has one program counter, specifying the location of the next instruction to execute. The process executes instructions sequentially, one at a time, until completion. A multithreaded process has one program counter per thread. Concurrency is achieved by multiplexing the CPUs among the processes or threads.

2. Process States

As a process executes, it changes its state:

• New: The process is being created.
• Running: Instructions

1. Non-Volatile Memory

Non-volatile memory retains stored information even when not powered. It is used for secondary storage or long-term persistent storage. Examples include:

• CD
• Hard Disk (similar reading and writing time)
• Solid-State Drive (SSD): No moving mechanical components, no difference for sequential vs. random reading, but a significant difference between reading and writing.
• ROM
• Flash Memory
• Magnetic Tape: Natural sequential reading and writing, suitable for backups.

2. File System

A file is a contiguous logical address space that can be written to, read from, opened, closed, and deleted. It has the following attributes:

• Name
• Unique ID
• Type
• Location
• Size
• Protection
• Date

Information about files is stored in file system structures.

3. Directory

A directory... Continue reading "File Systems: Structure, Management, and Optimization" »

It is said that using computers and the internet develops important skills in young people, and that makes them more concentrated in doing different things at the same time. It seems to me that the majority of young people have more skills than the previous generation, and they are so used to hearing and investigating different kinds of electronic machines. To start with, the use of computers and the internet can improve skills like logic, reasoning, motor skills, coordination, etc. It depends on what kind of use the young people give to the computer. For instance, the young people who usually play games develop many of these skills, especially those related to coordination. Another case would be young people who use social networks; they enhance... Continue reading "Developing Skills with Computers and the Internet in Youth" »
