Unit 2 Computer Systems HND in Computing and Systems Development Introduction Unit 2 Computer Systems HND in Computing and Systems Development

Approach You will already know most of this unit as specified by Pearson The computer systems are desktops We will start with LO3 and LO4 Build, configure, test and maintain systems Witness statements wherever possible, photographic evidence Individuals for desktop Pairs for server For LO1 and LO2 we will cover the basics rapidly, then go more into depth on architecture

Criteria LO1 Understand the function of computer systems 1.1 explain the role of computer systems in different environments 1.2 explain the hardware, software and peripheral components of a computer system 1.3 compare different types of computer systems LO2 Be able to design computer systems 2.1 produce a system design specification to meet a client’s needs 2.2 evaluate the suitability of a system design specification LO3 Be able to build and configure computer systems 3.1 build and configure a computer system to meet a design specification 3.2 test and document a computer system LO4 Be able to undertake routine maintenance on computer systems 4.1 perform routine maintenance tasks on a computer system 4.2 upgrade the hardware and software on a computer system.

Activity Write a test plan Carry out the tasks on the witness statement ACTIVITY  Safe working area   Configure BIOS (date/time, power, security) Electrostatic precautions Install OS (Note 3) Disassemble desktop PC (Note 1 and 2) Install security applications Install motherboard, CPU, heatsink, fan, memory Configure desktop Install power supply unit Configure storage including permissions Install drives Connect and install a peripheral Install graphics card Complete all tests on your test plan Note 1: Check correct operation before dismantling. Note 2: One person only to remove CPU, heatsink and fan, document for everybody. Cleaner and thermal paste available for refitting Note 3: Not required if already witnessed in Unit 26

Test plan Normal format Content Table of tests Table of problems POST Mouse/keyboard/monitor/USB ports OS boot, checkdisk, device manager, disk management, event logs, SMART disk analysis (Hiren’s boot USB), device drivers Installed software (AV, firewall, camera utilities) Configurations (desktop, storage) Operation of the peripheral

Configuration Date/time Security password on BIOS Boot order: USB, HDD, DVD Screen resolution, large fonts/icons Create additional admin user Create additional standard user Create folder for use by admins only Create task bar shortcut to admin folder
