Microsoft Word is a widely used word processing application that allows users to create, edit, and format documents. It is not a system software, which refers to the operating system and other low-level programs that manage the computer's hardware and software resources. It is also not shareware or freeware, as these terms refer to software distribution models rather than software types.

7. The Dean of Education wants the operating system (currently Windows 8.1) and the memory (currently 4Gb) of the PCs in the Faculty computer lab upgraded. Which combination will produce the best results?

Windows 8.2; 6Gb RAM

Windows 8.3; 8Gb RAM

Windows 10: 8Gb RAM

Windows 11; 8Gb RAM

This is a trick question because there is no Windows 8.2; Windows 8.3 and Windows 11 is not yet in view. So we are left with Windows 10 and an upgrade from 4Gb to 8Gb.

17. If you have N100,000 and you want to buy a very fast PC which of the following will you buy?

Atom

Celeron

Pentium

Corei7

The Corei7 processor would be the best choice for buying a very fast PC with N100,000. Corei7 processors are known for their high performance and speed, making them ideal for demanding tasks such as gaming, video editing, and multitasking. They have multiple cores and threads, allowing them to handle intensive processes efficiently. Atom, Celeron, and Pentium processors are generally less powerful and are more suitable for basic tasks such as web browsing and word processing.

18. You are given a choice of PC as New Year (2017) present. Your main goal is to have a machine with storage for your files that is fast to access and relatively noiseless. What will be your best choice?

500Gb SSD

500Gb HDD

1TB HDD

2TB HDD

The Solid State Drive (SSD) is the quiet drive and fast to access. Three of the machines in the list have HDD drives even though of huge storage capacity. 500Gb SSD is tolerably huge.

19. The hard drive (disk) of your laptop is full. What will be your best line of action?

Reformat the drive.

Install an extra drive.

Offload some content into a flash drive.

Remove the full drive and install a new one

The best line of action when the hard drive of your laptop is full is to offload some content into a flash drive. This will free up space on the hard drive and allow you to continue using your laptop without any issues. Reformatting the drive would erase all the data, installing an extra drive may not be necessary if you can free up space, and removing the full drive and installing a new one would require additional hardware and may not be the most cost-effective solution.

20. The Vice-Chancellor has ordered laptops for all staff in LASU. A Committee has recommended the four options below. Which of the options will be best value for money?

13”, 8Gb SRAM, 500 SSD, Corei7

13”, 8Gb DRAM, 500 HDD, Corei3

15”, 8GB DRAM, 1TB HDD, Corei3

20”, 16Gb DRAM, 500Gb HDD, Pentium 4

All others except B will be an overkill for staff. SSD is super expensive (more than double cost of HDD). Most staff do not need more than 500Gb HDD storage. Corei3 processor will be just fine for staff as it is fast enough. Corei7 processors are expensive. Contributions by many staff to the Discussion Forum of Wednesday support this.
