Which of the following sleep modes is also known as Hibernation in Windows operating systems?
Answer: C Explanation:
The S4sleep mode is also known as Hibernation or hibernate mode in Windows operating systems. Hibernate mode is a power saving feature for computers. In hibernate mode, the current state of a computer is saved to the hard disk, and the computer shuts down. A user will have to power on the computer to restore the previous settings. When a computer resumes from hibernate mode, it reads the saved settings from the disk and restores the system state as it was before it entered hibernate mode. By default, hibernate mode is disabled. If a computer is not ACPI-enabled or APM-enabled, users will have to enter hibernate mode manually. Users cannot set the computer to automatically hibernate after a certain time. With ACPI-enabled and APM-enabled computers, users are able to set hibernate mode automatically.
Answer option D is incorrect. The S1 mode is the most power hungry sleep mode. In this mode, the
CPU stops executing instructions and the processor cash is flushed, but power is still supplied to the CPU and memory. Allother unused devices are powered down.Answer option B is incorrect. The S2 mode uses less power than S1 mode. In this mode, the computer#39;s processor is powered down. Answer option A is incorrect. The S3 mode is also known as Stand by mode. In this mode, the computer supplies power only to the RAM. This mode is also known as Suspend to RAM.

Your client currently has Windows 98 and wishes to upgrade to Windows XP. What is the most efficient way to accomplish this goal?
Buy and installthe Windows XP Upgrade.
Install a full copy of Windows XP.
First upgrade to Windows 2000, then to Windows XP.
You cannot upgrade from Windows 98 to XP.
Answer: A Explanation:
Windows 98 can be upgraded directly to Windows XP.
Answer option C is incorrect. This is not necessary (but would work).
Answer option B is incorrect. Installing a fresh new copy does not keep the configurations, programs, etc. from the old copy. Upgrading is the best approach here. Answer option D is incorrect. You can upgrade from Windows 98 to XP.

In which of the following sizes are the Express Card modules available? Each correct answer represents a complete solution. Choose two.
54 mm Wide
64 mm Wide
20 mm Wide
34 mm Wide
Answer: A,D Explanation:
Express Card is a thinner, faster, and lighter modular expansion for desktops and laptops. Users can add memory, wired or wireless communication cards, and security devices by inserting these modules into their computers.
Express Card slots are designed to accommodate modules that use either Universal Serial Bus (USB) 2.0 or the PCI Express standard. Express Card modules are available in two sizes, i.e., 34 mm wide (Express Card/34) and 54 mm wide (Express Card/54). Both modules are 75 mm long and 5 mm high.
An Express Card/34 module can be inserted in either a 54 mm slot or a 34 mm slot, but an Express Card/54 requires a Universal (54 mm) slot. However, an extender can be used with Express Card/34 slot to connect the Express Card/54 module from outside of the computer.
Both the modules are identical in performance. They take full advantage of the features of the PCI Express or USB 2.0 interfaces. The only difference between them is that the Express Card/54 formor, due to its larger surface area, allows for greater thermal dissipation than does an Express Card/34. As the performance does not vary with module size, module developers usually prefer to fit their applications into the smaller Express
Card/34 form or. But some applications, such as
SmartCard readers, and CompactFlash readers, require the extra width of an Express Card/54 module. Reference. quot;http.//en.wikipedia.org/wiki/Express Cardquot;

Which of the following expansion slots can be used to plug a SCSI adapter? Each correct answer represents acomplete solution. Choose all that apply.
Answer: A,C,E Explanation:
Small Computer System Interface (SCSI) adapters can fit on PCI, EISA, and VESA slots. Unlike IDE, SCSI interface is generally not built-in onthe motherboard. However, some motherboards do come with integrated SCSI adapters. In most cases, you have to purchase a SCSI adapter and install it into a bus slot. Once the SCSI adapter is installed, you can connect the SCSI devices to the host adapter.
What is SCSI?
Small Computer System Interface (SCSI) is the second most popular drive interface in use today after the Integrated Drive Electronics (IDE) interface. SCSI is faster than IDE and supports more devices.
SCSI devices, such as hard disk drive and CD-ROM drive, are better suited in a network environment in which many users access shared drives simultaneously. SCSI has three standards. SCSI-1, SCSI- 2,and SCSI-3.
What is a VESA bus?
VESA is an expansion bus standard developed by Video Electronics Standards Association to provide high-performance video and graphics capabilities.
What is a PCI bus?
Peripheral Component Interconnect (PCI) is a high-performance, 32-bit or 64-bit bus designed to be used with devices that have high bandwidth requirements,such as the display subsystem.
What is an EISA bus?
Extended Industry Standard Architecture (EISA) is a 32-bit PC expansion bus designed as a superset of a 16-bit ISA bus.
The EISA bus is designed to increase the speed and expand the data width of the legacy
expansion bus while still supporting older ISA cards. This is accomplished by providing the slot with two layers of connectors. The top layer is identical to a 16-bit ISA slot. The bottom layer is used by an EISA device but ignored by an ISA device. Therefore, both ISA and EISA devices can work in an EISA slot.
Answer options B and D are incorrect. Slot1 and Slot2 are used for Pentium III processors and Pentium Xeon processors, respectively.

Which of the following terms refers to proprietary software that is provided to users without payment on a trial basis and isoften limited by any combination of functionality, vailability or convenience?
Answer: B Explanation:
Shareware is a term refers to proprietary software that is provided to users without payment on a trialbasis and is often limited by any combination of functionality, vailability or convenience. Answer option A is incorrect. Spyware is a program that takes partial control over a user#39;s computer without user#39;s permission. Spyware programs can collect varioustypes of personal information, such as Internet surfing habits, and Web sites that the user has visited. Spyware programs can also interfere with the control of a user#39;s computer, such as installing additional software, redirecting Web browser activities,accessing Web sites blindly, etc.
Answer option C is incorrect. Freeware is term for computer software that is available for use at no cost or for an optional fee. Answer option D is incorrect. Adware is software that automatically downloads and display advertisements in the Web browser without user permission. When a user visits a site or downloads software, sometimes a hidden adware software is also downloaded to display advertisement automatically. This can be quite irritating to user. Some adware can also be spyware.

Which of the following ports on a computer are used to connect a keyboard? Each correct answer represents a complete solution. Choose two.
Answer: A,C Explanation:
The PS/2 and USB ports on a computer are used to connect a keyboard. What is USB?
Universal Serial Bus (USB) is a high speed bus standard developed by Compaq, IBM, DEC, Intel, Microsoft, NEC, and Northern Telecom. It provides the Plug and Play capabilityof Windows to external hardware devices. USB supports hot plugging, which means that a USB device can be installed or removed while the computer is running. A single USB port can be used to connect up to
127 peripheral devices, such as CD-ROM drives, tapedrives, keyboards, scanners etc. USB 1.1 has a maximum data transfer rate of 12 Mbps, whereas USB 2.0 has a maximum data transfer rate of 480
Mbps. USB 2.0 is fully backward compatible with USB 1.1.
Answer options D and B are incorrect. The DB-9 and DB-25port types on the computer are used as serial ports. A DB-9 male type port has 9 pins, whereas a DB-25 male type port has 25 pins.
What is a serial port?
Serial port is the primary means for connecting modems and mouse to a computer. There are two types ofserial port connectors, 9-pin and 25-pin. The word serial refers to the data is sent in series, one bit at a time, over a single wire. This design is significantly slower than sending 8 bits at a time via a parallel channel, but serial signals can travelmuch farther without degradation.
