SYS AD FINALS REVIEWER

Can be defined as an interface between user and the hardware.

The Operating System Tutorial is divided into various parts based on its functions such as Process Management, Process Synchronization, Deadlocks and File Management.

A Computer System consists of:

Refers to management of Primary Memory or Main Memory. Main memory is a large array of words or bytes where each word or byte has its own address.

In multiprogramming environment, the OS decides which process gets the processor when and for how much time.

An Operating System manages device communication via their respective drivers.

A file system is normally organized into directories for easy navigation and usage. These directories may contain files and other directions.

It is important functions of OS are that prevents unauthorized access to programs and data.

It is important functions of OS are that records the delays between request for a service and response from the system.

It is important functions of OS are that keeps track of time and resources used by various jobs and users.

It is important functions of OS are: Production of dumps, traces, error messages, and other debugging and error detecting aids.

___________ access is given to more than one person; they submit their respective jobs to the system for the execution.

______________ is an extension to the batch processing where the CPU is kept always busy. Each process needs two types of system time: CPU time and IO time.

This type of operating system that Parallel computing is achieved. There are more than one processors present in the system which can execute more than one process at the same time. This will increase the throughput of the system.

This type of operating system that each job carries a certain deadline within which the Job is supposed to be completed, otherwise the huge loss will be there or even if the result is produced then it will be completely useless.

Batch processing suffers from _____________.

One of the Disadvantage of Batch Processing is not suitable for the jobs which are dependent on the user's input

In the era of 1970s, the _________ processing was very popular.

What is the unique characteristic of RAID 6?

Which of the following is correct about hardware RAID controllers?

RAID initials mean?

RAID 0 does not improve safety compared to conventional hard disk.

A regular file is used to represent hardware devices such as hard disks, terminals, printers, mouse and keyboard.

_____ provide a large number of services to application programs with a unified view of the network.

Which RAID type doesn’t use parity for data protection?

Which of the following combinations can support RAID 5?

Which one of these is characteristic of RAID 5?

It is a structure used to organize programs and data on a computer's storage device.

One of the configurations allows reading the data more efficient?

RAID 10 is applicable from three combined hard drives.

Which of these RAID modes makes the most of the storage capacity of hard drives?

_____ and _____ are the two type of files.

The set of protocols that define communication over the Internet.

_____ is required to provide full security for a Windows file server.

What is the minimum number of disks required for RAID1?

Can you help decide on the RAID level to use – we are a media house and we use lot of graphics/video applications – we need large throughputs for videos to get played without any jitter and since we are in publishing business we can’t afford downtimes. Even if there is any downtime we would like our data to be quickly reconstructed and enable us to continue without work in less time.

A _____ is a set of network protocol layers that work together.

How is called RAID 0 mode?

An array of disks is more likely to fail compared to a single disk. How is it that RAID arrays still manage to provide more data protection compared to a single disk?

_____ and _____ are the advantages of a client/server network.

types of multitasking NOS,where the processes are assigned CPU time slices by the operating system

Types of multitasking NOS, where the operating system has no control over the processes

Older file system

Modern replacement file system

The most modern file system

____________ is a brand name for a group of server operating systems released by Microsoft.

The first Windows server edition to be released under that brand was __________.

What is the the first server edition of Windows?

____________ is the fifth version of the Windows Server operating system by Microsoft, as part of the Windows NT family of operating systems.

What are the two pre-release versions of windows?

Windows Server 2012 runs only on x64 processors. Unlike its predecessor, Windows Server 2012 does not support Itanium.

Upgrades from Windows Server 2008 and Windows Server 2008 R2 are supported, upgrades from prior releases/

___________ is an emulation of a computer system.

VMware Workstation is a virtual machine software that is used for x86 and x86-64 computers to run multiple operating systems over a single physical host computer.

Each virtual machine can run a single instance of any operating system (Microsoft, Linux, etc.) simultaneously.

VMware Workstation strongly supports hardware compatibility and works as a bridge between the host and virtual machine for all kinds of hardware resources including hard disks, USB devices and CD-ROMs.

All device drivers are not installed via the host machine.

Windows Server is a brand name for a group of server operating systems released by Apple.

Windows Server 2013 is the fifth version of the Windows Server operating system by Microsoft

It is the server version of Windows based on Windows 8 and succeeds Windows 7-based Windows Server 2008 R2, released two years prior.
