Definition
the motherboard is the computer component that interconnects all other components

Serial (COM) ports come in two flavors: DB9-male and DB25-male. Parallel ports come only in DB25-female ports.

two main types of cache memory are L1 and L2 cache. L1 cache memory is integrated into the processor, and L2 cache is contained outside the processor but in the processor casing or on the motherboard.

IDE supports two devices in the IDE chain, whereas EIDE has two channels with two devices in each channel (totaling four devices).

A number of major motherboard form factors are available: Full AT, Baby AT, NLX, and ATX. Motherboard form factors differ in the size of the board and the layout of the components stored on the board.

you may add components, such as a sound card or network card, to the computer by inserting an expansion card into one of the expansions slots in the system.

ISA was the popular bus architecture for years, but because of its limitations (16-bit architecture and speed of 8 MHz), it has been replaced by the PCI bus architecture. PCI is a 32-bit/64-bit architecture with speeds of 33MHz

AGP and PCI express are the common bus architectures used to insert a video card in todays systems.

you may increase the performance of the system by using a faster motherboard or by purchasing better-performing expansion cards.

When CPU requests data from memory it verifies that the parity bit that was stored with said memory matches with the one it generated. If match, integrity of info is considered OK.

If no match, it's Parity Error: problem with integrity of the data stored in memory.
Term

- half stores frequently accessed program 'data'
Term

Definition
Read-only Memory (ROM): memory that can be read from but not written to. Info here is permanent.

Random access memory (RAM): volatile memory that can be written to and read; info stored here is flushed out when power is lost.

Dynamic RAM (DRAM): emory that needs constant refreshing of its memory cells; it is also typically upgraded on systems

Static RAM (SRAM): static memory, does not need refreshing as often as DRAM. SRAM is faster and is used for cache memory.

Cache memory: todays processors have L1 and L2 cache unique to each processor core as well as an L3 pool for all the cores.

memory modules: 72-pin SIMMs used to be popular on Pentium systems. DIMMs are now the main type for desktops and SODIMMS are laptops.

- Authentication is the process of proving an identity to the network, but Authorization is the process of determining whether accessing a resource is allowed after authentication takes place.

- Hackers take many different approaches to compromise a system. Protect your environment from both network-based and software-based attacks, and make sure that physical security is in place.

- a denial of service (DoS) is an attack on a system or network that prevents the system or network from performing it's regular function.

- Social engineering is a popular type of attack involving the hacker compromising security by tricking an employee through social contact.

- You secure network traffic by encyrpting traffic between two systems by using technologies such as SSL and IPSec. Admins typically use SSL to encrypt web traffic and IPSec to encrypt internal or VPN traffic.

- securing your data involves not only protecting resources with permissions but also protecting your data by following proper data destruction procedures and backup strategies as well as creating redundant disk solutions.
