5. Why is the distinction between wide area networks (waNs) and local area networks (laNs)?

Local area networks and wide area networks are essentially the same in many aspects. They only differ in the area that is covered by the network. LANs are networks that are limited to a small geographic location. The computers connected to the network could be in a single room, a few rooms, or spread out in an entire building. WANs, on the other hand, cover great distances and are not limited to a single location. The biggest and most popular example of a WAN is the internet, which spans the whole globe and has millions of computers connected to it.

LAN covers a small area while WAN covers a significantly larger area.

LAN speeds are also significantly faster than WAN.

LAN is more secure than WAN.

WAN is much more expensive to implement than LAN.

6. How is it possible to differentiate spell checkers from grammar checkers?

7. What are the main functions of spell checkers?

8. What are the main functions of grammar checkers?

Grammar checkers are ubiquitous tools of many writers who use word processing software. Their main function is to detect language errors in written form found within software-written documents and to offer suggested corrections. Grammar checkers differ in implementation and features. Writers who rely on word processors would benefit from knowing how grammar checkers function and perform

9. Could you compare such operating systems as MS DOS and Windows XP?

During the 20th century, Windows operating systems (OS) effectively overtook DOS for nearly all home computer users. However, this was not always the case. Many programs originally appeared only in DOS or with a viable DOS version. WordPerfect is a prominent example. Although Microsoft released the last version of MS-DOS in 1994, Windows owes much of its functionality to the existence of DOS.

What is DOS?

DOS is an acronym that stands for disk operating system. The original name was MS-DOS, which is also an acronym, with MS being an abbreviation for Microsoft. DOS was developed as the original OS for IBM-compatible computers in 1981. It is a compact program that requires limited conventional memory, and almost no video resources or drivers. However, MS-DOS is a 16-bit program with limited graphics capacity. It also does not support multitple users or multitasking.

What is Windows?

Windows is a graphical user interface (GUI) based program. It differs from DOS in that DOS requires command-line entries for execution. Windows, on the other hand, provides an ostensibly user-friendly means for the user to execute commands through mouse clicks and menu choices rather than command-line commands. However, early versions of Windows were dependent upon DOS to operate. Later versions of Windows did not share this dependence, although they did allow users to execute limited DOS commands.

10. Could you interpret the meaning “multi-tasking’ in the work of an operating system?

When a single program is allowed to run at a time, the system is grouped under a single-tasking system, while in case the operating system allows the execution of multiple tasks at one time, it is classified as a multi-tasking operating system. Multi-tasking can be of two types namely, pre-emptive or co-operative. In pre-emptive multitasking, the operating system slices the CPU time and dedicates one slot to each of the programs. Unix-like operating systems such as Solaris and Linux support pre-emptive multitasking. Cooperative multitasking is achieved by relying on each process to give time to the other processes in a defined manner. MS Windows prior to Windows 95 used to support cooperative multitasking.
