1. Consultar los comandos que permiten hacer lo siguiente en PowerShell:

• Información del hardware 🡪Get-WmiObject -Class Win32_ComputerSystem

[pic 24]

• Información de la BIOS🡪  Get-WmiObject Win32_BIOS

[pic 25]

• Muestra el usuario que está conectado en el sistema. 🡪 Get-WmiObject Win32_ComputerSystem

[pic 26]

• Aplicaciones Instaladas 🡪 Get-WmiObject -Class Win32_Product -ComputerName . | Format-Wide

[pic 27]

• Mostrar IP 🡪 Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter IPEnabled=TRUE -ComputerName . | Format-Table -Property IPAddress

[pic 28]

• TOP 5 Procesos con más consume 🡪 ps | sort -p ws | select -last 5

[pic 29]

• Listar Ítems de directorio 🡪 Get-ChildItem -Force

[pic 30]

• renombrar varios archivos a la vez🡪 dir | rename-item -newname {$_.name -replace “prueba”, “intento”}

[pic 31]

[pic 32]

• Mostrar fecha y diferencias de dias entre dos fechas

[pic 33]

EJERCICIO 2

1. Explain the differents methods for memory management

• First In First Out - FIFO
• Shortest Remaining Time (S.R.T.)
• Shortest-Job-First (S.J.F.)
• Round Robin

Make a comparative table between the different algorithms of memory management, explaining the advantages and disadvantages of each of them

• First In First Out - FIFO

The processes are serviced in the order in which they entered the Ready list. The process is assigned the CPU until it finishes its execution.[pic 34]

• Shortest Remaining Time (S.R.T.)

Once a process begins its execution, it can be displaced by a new one with a lower estimated execution time.

• Shortest-Job-First (S.J.F.)

The standby process that has the next shortest estimated execution time runs first, until it terminates.

• Round Robin

It consists of assigning the CPU to the first process on the Ready list during a run time (Quantum), which is the same for all processes.

[pic 35]

1. Make the analysis of four different processes initiated and the operation of each algorithm of.

• First In First Out - FIFO
• Shortest Remaining Time (S.R.T.)
• Shortest-Job-First (S.J.F.)
• Round Robin

• First In First Out - FIFO

• Shortest Remaining Time (S.R.T.)
