True or False? If there are no empty memory expansion sockets on the system board, you will need to remove an existing module and replace it with a module that contains more memory.
-
True
-
False
Correct Answer
A. TrueExplanation
If there are no empty memory expansion sockets on the system board, it means that there is no available space to add more memory modules. In this case, the only way to increase the memory capacity of the system is to remove an existing module and replace it with a module that has more memory. Therefore, the statement is true.Rate this question:

What is WiFi
-
Select Bluetooth for short-range communications when you cannot establish a line-of-sight connection between two devices and you can tolerate relatively slow data transfer speeds
-
Use infrared for short-range communications when you want to take advantage of its relatively fast transfer speeds and you are able to establish a line of sight connection between devices. Ideally, infrared devices work best when you place them from 5 cm (2 inches) to 60 cm (24 inches) apart.

Wireless radio communications following the IEEE 802.11b “WiFi” standard are the most common choice for ordinary wireless LAN connectivity for portable computers inside homes, offices, and, increasingly, public buildings. Choose WiFi when you need to connect portable computer systems to a wired or wireless Ethernet LAN and enable users to move from place to place freely without a line of site connection to the WAP.
-
Use a cellular Wireless WAN (WWAN) when you have users that have no other way to connect to the Internet, your company’s VPN, or both. Cellular WWANs are typically more expensive than Ethernet WANs
Correct Answer
A. Wireless radio communications following the IEEE 802.11b “WiFi” standard are the most common choice for ordinary wireless LAN connectivity for portable computers inside homes, offices, and, increasingly, public buildings. Choose WiFi when you need to connect portable computer systems to a wired or wireless Ethernet LAN and enable users to move from place to place freely without a line of site connection to the WAP.Explanation
WiFi, or wireless radio communications following the IEEE 802.11b standard, is the most common choice for ordinary wireless LAN connectivity for portable computers. It is ideal for use inside homes, offices, and public buildings. WiFi allows users to connect their portable computer systems to a wired or wireless Ethernet LAN, enabling them to move freely without requiring a line of sight connection to the wireless access point (WAP).Rate this question:

Where is the system BIOS stored?
-
On a ROM chip.
-
In standard RAM.
-
In CMOS RAM.
-
On the primary hard drive.
Correct Answer
A. On a ROM chip.Explanation
The system BIOS is stored on a ROM chip. ROM stands for Read-Only Memory, which means that the data stored in it cannot be modified or erased. The BIOS (Basic Input/Output System) is responsible for initializing and controlling the hardware components of a computer system. It contains the instructions that allow the computer to start up and perform basic functions before the operating system takes over. Storing the BIOS on a ROM chip ensures that it remains intact even when the computer is powered off, providing a stable and reliable source of instructions for the system.Rate this question:

When installing a pata hard disk in a computer, which of the following jumper setting do not apply?
-
Master
-
Slave
-
Cable select
-
Chkdsk
Correct Answer
A. ChkdskExplanation
The jumper settings Master, Slave, and Cable select are used to specify the role of the PATA hard disk in the computer's IDE (Integrated Drive Electronics) interface. The Master setting is used when the hard disk is the primary drive, the Slave setting is used when it is the secondary drive, and the Cable select setting allows the computer to automatically determine the roles based on the physical cable connections. On the other hand, chkdsk is a command used in Windows operating systems to check and repair file system errors on a disk, but it is not a jumper setting for the hard disk.Rate this question:

Correct Answer
A. Cleaning, Conditioning,Writing ,Developing,Transferring,FusingExplanation
The correct order of operation for a laser printer is as follows: Cleaning, Conditioning, Writing, Developing, Transferring, Fusing. This order ensures that the printer is properly cleaned before the printing process begins. Conditioning prepares the paper for printing, while writing refers to the laser beam creating the image on the drum. Developing involves applying toner to the drum, transferring transfers the toner to the paper, and fusing uses heat to bond the toner to the paper.Rate this question:

...........................terminal emulation protocol that enables a user at one site to simulate a session on a remote host.
-
Telnet
-
FTP
-
HTTP
-
POP3
Correct Answer
A. TelnetExplanation
Telnet is the correct answer because it is a terminal emulation protocol that allows a user to establish a remote connection to a host computer. It enables the user to simulate a session on the remote host, giving them access to the command line interface and the ability to execute commands as if they were physically present at the remote site. FTP, HTTP, and POP3 are not terminal emulation protocols and do not provide the same level of remote access and control as Telnet.Rate this question:

-
CLASS 4
-
CLASS 3
-
CLASS 1
Correct Answer
A. CLASS 4Explanation
Class 4 lasers pose danger to eyes and skin, as well as being fire hazards. Unlike Class 1, 2, and 3 lasers, Class 4 lasers have the highest power output and can cause immediate damage to the eyes and skin upon exposure. They are also capable of starting fires due to their high energy levels. Therefore, it is important to handle Class 4 lasers with caution and use appropriate safety measures to prevent any accidents or injuries.Rate this question:

MR. Tej want to apply for ip address for a small compny having not more than 100 computerinb their network. which class of ip address he should apply for?
-
Class D
-
Class A
-
Class B
-
Class C
Correct Answer
A. Class CExplanation
For a small company with not more than 100 computers in their network, MR. Tej should apply for a Class C IP address. Class C IP addresses are designed for small networks and can support up to 254 hosts per network. They have a default subnet mask of 255.255.255.0, which allows for 256 possible network addresses. This is sufficient for MR. Tej's company as it falls within the range of 1 to 126, making it suitable for small-scale networks. Class A and Class B addresses are typically used for larger networks, while Class D addresses are reserved for multicast addresses.Rate this question:

The least sensitive to EMI of any cable type
Correct Answer
A. The least sensitive to EMI of any cable typeExplanation
IEEE 1394 is a high-speed serial bus standard used for connecting devices such as computers, audio/video equipment, and storage devices. It is known for its ability to transmit data quickly and efficiently. However, it is not true that IEEE 1394 is the least sensitive to electromagnetic interference (EMI) of any cable type. While it does have some resistance to EMI, there are other cable types that are specifically designed to be more resistant to interference, such as shielded twisted pair cables.Rate this question:
