What does the x stand for in AGP 8x?

What does the x stand for in AGP 8x?

• Times Graphic Speed
• Times FSB Speed
• Times CPU Speed
• Times original AGP Speed [Times the bus speed ]

EXPLANATION

AGP (Accelerated Graphics Port) is a high-speed 32-bit port from Intel for attaching a display adapter to a PC. It provides a direct connection between the card and memory, and only one AGP slot is on the motherboard.
AGP was introduced as a higher-speed alternative to PCI display adapters, and it freed a PCI slot for another peripheral device. The brown AGP slot is slightly shorter than the white PCI slot and is located about an inch farther back. AGP is superseded by PCI Express.

What range of values does Hexadecimal use?

What range of values does Hexadecimal use?

• 0-9 and A-F
• 1-17
• 0-16
• 1-10 and A-E 

 

EXPLANATION

In mathematics and computing, hexadecimal (also base 16, or hex) is a positional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the symbols 0–9 to represent values zero to nine, and A, B, C, D, E, F(or alternatively a, b, c, d, e, f) to represent values ten to fifteen.

Macro, Micro, Pico, Femto and Umbrella are all types of what?

Macro, Micro, Pico, Femto and Umbrella are all types of what?

• Cell sizes in a GSM network
• GSM filters
• GSM interfaces
• Uplink and downlink channels 

EXPLANATION

GSM mobile phone networks are "cellular," which means that mobile phones connect to it by nearest cell.
MACRO cells can be regarded as cells where the base station antenna is installed on a mast or larger building structures that are taller than an average roof-top level. Cell radius is typically from 1 up to 35 km.
MICRO cells are cells whose antenna height below average rooftop level and are typically used in urban areas. Size is from 400 m to 2 km. 
PICO cells are small cells whose diameter is only few dozen meters; they are used mainly in indoor applications.
UMBRELLA cells: A layer with micro cells is covered by at least one macro cell, and a micro cell can in turn cover several pico cells. A covering cell is called an umbrella cell.

Which of the following is not a requirement of an elastic system?

Which of the following is not a requirement of an elastic system?

• CPU, GPU, RAM, storage availability
• Provision/deprovision resources
• Monitor resource usage
• Leprechauns

 

EXPLANATION

According to a paper from Karlsruhe Institute of Technology, "Elasticity is the degree to which a system is able to adapt to workload changes by provisioning and deprovisioning resources in an autonomic manner, such that at each point in time the available resources match the current demand as closely as possible." https://sdqweb.ipd.kit.edu/publications/pdfs/HeKoRe2013-ICAC-Elasticity.pdf
Resources such as CPU cycles, RAM, and storage are all necessary to provision to a client account. What makes elasticity different from simply being scale-able is that systems can be automated to add or remove these resources pending the outcome of a monitoring routine. Generally speaking, an elastic system doesn't require a Leprechauns to operate.

Which type of RAID configuration requires minimum six drives?

Which type of RAID configuration requires minimum six drives?

• RAID 60 (RAID 6 + 0)
• RAID 50 (RAID 5 + 0)
• RAID 100 (RAID 10+0)
• RAID 6 

 

EXPLANATION

RAID 50, also called RAID 5+0, combines the straight block-level striping of RAID 0 with the distributed parity of RAID 5.[3] As a RAID 0 array striped across RAID 5 elements, minimal RAID 50 configuration requires six drives.

When it comes to associative memory, how does the memory locate the address of the data?

When it comes to associative memory, how does the memory locate the address of the data?

• The address of the data is supplied by the users
• The address of the data is generated by the CPU
• The data are accessed sequentially
• There is no need for an address, the data is used as an address 

 

EXPLANATION

Associative memory is memory capable of determining whether a given datum (the search word) is contained in one of its addresses or locations. Associative memory  is also referred to as content-addressable memory.
Unlike standard computer memory (random access memory or RAM) in which the user supplies a memory address and the RAM returns the data word stored at that address, associative memory is designed such that the user supplies a data word and the computer searches its entire memory to see if that data word is stored anywhere in it.
