Computer Operating System Questions and Answers

Answer: A

Correct answer: you can set different size for each recycle bin

Each drive keeps its own recycle bin, and the settings dialog lets you configure the drives independently, giving each one a different percentage of its capacity for deleted files. What you cannot do is choose which bin a deleted file goes to - that is decided by the drive it was deleted from - or nominate one as a default.

Answer: D

Correct answer: Control panel

The system clock is set from the Control Panel’s date and time settings - or by double-clicking the clock in the taskbar, which opens the same dialog. Write is a text editor and Calendar merely displays dates.

Answer: D

Correct answer: All of the above

All three are hostile programs a machine must be defended against: a virus attaches itself to a file or boot sector and spreads when that is used; a worm propagates across a network by itself; and a time bomb lies dormant until a set date and then does its damage.

Answer: D

Correct answer: Process Control

A process control system is real-time: it must respond to sensor readings within a deadline set by the plant it controls, since a late correction is useless. MS-DOS, Windows XP and Lynx’s desktop products aim at convenience and throughput, with no guaranteed response time.

Answer: D

Correct answer: MS DOS

MS-DOS is single-tasking: it runs one program at a time and offers no scheduler, which is why background behaviour had to be faked with terminate-and-stay-resident tricks. Windows 98, NT and XP all schedule several processes genuinely concurrently.

Answer: C

Correct answer: Windows XP

Windows XP was the first of these released in a 64-bit edition - XP 64-bit Edition for Itanium, then XP Professional x64 for AMD64 and Intel 64 processors. Windows 95, 98 and 2000 Professional shipped only as 32-bit systems.

Answer: D

Correct answer: MS DOS

MS-DOS is single-tasking: it runs one program at a time and has no scheduler, which is why background behaviour had to be faked with terminate-and-stay-resident tricks. Windows 98, NT and XP all schedule several processes genuinely concurrently.

Answer: D

Correct answer: Windows 2000

Windows 2000 Server is the one built for the role: it carries Active Directory, domain authentication, DNS and DHCP services, and centrally managed file and print sharing. MS-DOS and the Windows 9x line offer only peer-to-peer sharing, with no domain and no central account database.

Answer: D

Correct answer: Windows 2000

Windows 2000 is the only one of these with a server edition, bringing Active Directory, domain logon, and centrally administered file, print and application services. Windows 95 and 98 support peer-to-peer sharing but have no domain controller and no central security database, and MS-DOS has no networking of its own at all.

Answer: C

Correct answer: Windows 8

Windows 8 dropped the Start button from the desktop taskbar, replacing the Start menu with the full-screen Start screen - a change so unpopular that Windows 8.1 restored the button and Windows 10 restored the menu. Vista and 7 both have it.
